    Full Text Available Today, in spite of the developments in imaging methods and antibiotherapy, childhood pleural empyema is a prominent cause of morbidity and mortality. In recent years, it has been shown that there has been an increase in the frequency of pleural empyema in children, and antibiotic resistance in microorganisms causing pleural empyema has made treatment difficult. Despite the many studies investigating thoracoscopic debridement and fibrinolytic treatment separately in the management of this disease, there is are not enough studies comparing these two treatments. The aim of this study was to prospectively compare the efficacy of two different treatment methods in stage II and III empyema cases and to present a perspective for treatment options. We excluded from the study cases with: i thoracoscopic intervention and fibrinolytic agent were contraindicated; ii immunosuppression or additional infection focus; iii concomitant diseases, those with bronchopleural fistula diagnosed radiologically, and Stage I cases. This gave a total of 54 cases: 23 (42.6% in stage II, and 31 (57.4% cases in stage III. These patients were randomized into two groups of 27 cases each for debridement or fibrinolytic agent application by video-assisted thoracoscopic decortication (VATS. The continuity of symptoms after the operation, duration of thoracic tube in situ, and the length of hospital stay in the VATS group were of significantly shorter duration than in the streptokinase applications (P=0.0001. In 19 of 27 cases (70.37% in which fibrinolytic treatment was applied and in 21 cases of 27 (77.77% in which VATS was applied, the lung was fully expanded and the procedure was considered successful. There was no significant difference with respect to success rates between the two groups (P=0.533. The complication rate in our cases was 12.96% and no mortality was observed. Similar success rates in thoracoscopic drainage and enzymatic debridement, and the low cost of enzymatic

    Over a 20-year period, 34 patients with FIGO stage II ovarian carcinoma were treated with postoperative pelvic irradiation at the University of Michigan. Complications of radiation treatment were minimal. The overall actuarial disease-free 5-year survival was 53%. This was not significantly different for substages IIA, IIB, or IIC. Patients with well-differentiated tumors had a significantly better survival than patients with moderate or poorly differentiated tumors (P less than 0.05). The implications for managing stage II ovarian carcinoma are discussed

    Co-expression of ERBB2 and ERBB4, reported in 75% of pediatric ependymomas, correlates with worse overall survival. Lapatinib, a selective ERBB1 and ERBB2 inhibitor has produced prolonged disease stabilization in patients with ependymoma in a phase I study. Bevacizumab exposure in ependymoma xenografts leads to ablation of tumor self-renewing cells, arresting growth. Thus, we conducted an open-label, phase II study of bevacizumab and lapatinib in children with recurrent ependymomas. Patients ≤ 21 years of age with recurrent ependymoma received lapatinib orally twice daily (900 mg/m(2)/dose to the first 10 patients, and then 700 mg/m(2)/dose) and bevacizumab 10 mg/kg intravenously on days 1 and 15 of a 28-day course. Lapatinib serum trough levels were analyzed prior to each course. Total and phosphorylated VEGFR2 expression was measured in peripheral blood mononuclear cells (PBMCs) before doses 1 and 2 of bevacizumab and 24-48 h following dose 2 of bevacizumab. Twenty-four patients with a median age of 10 years (range 2-21 years) were enrolled; 22 were eligible and 20 evaluable for response. Thirteen had anaplastic ependymoma. There were no objective responses; 4 patients had stable disease for ≥ 4 courses (range 4-14). Grade 3 toxicities included rash, elevated ALT, and diarrhea. Grade 4 toxicities included peri-tracheostomy hemorrhage (n = 1) and elevated creatinine phosphokinase (n = 1). The median lapatinib pre-dose trough concentration was 3.72 µM. Although the combination of bevacizumab and lapatinib was well tolerated in children with recurrent ependymoma, it proved ineffective.

    Twenty eight patients with stage II A and twenty patients with stage II B testicular seminoma were treated at this institute between January 1982 and December 1988. The three year crude survival observed in this retrospective analysis was 82% and 75% respectively. Post orchiectomy infradiaphragmatic radiotherapy was the mainstay of the treatment. In stage II A, 4 patients were administered adjuvant chemotherapy as well. Prophylactic mediastinal irradiation (PMI) was not employed as a routine in this subgroup. Eight patients (28%) relapsed (mediastinal nodes - 4, pulmonary - 3, scrotal - 1). In stage II B, twelve patients were treated with primary abdominal radiotherapy and of them 4 were delivered PMI as well. Induction chemotherapy was administered in remaining 8 patients. Seven patients (35%) relapsed (pulmonary-4, mediastinal nodes-3). Mediastinal recurrence was noted only in those who were treated with abdominal radiotherapy alone. Though salvage chemotherapy proved successful in 5 of the seven patients (70%) with nodal relapse, none of the patients with extranodal relapse responded to subsequent chemotherapy. For stage II A abdominal radiotherapy alone is recommended and for stage II B induction chemotherapy is advised keeping radiotherapy reserved for residual mass. PMI as a routine in stage II testicular seminoma is not advocated as no survival benefit is observed. (author) 15 refs., 6 tabs

    A review of the Princess Margaret Hospital (Toronto, Canada) experience over the last 20 years in treating clinically staged patients with stage I and II Hodgkin's disease was performed to analyse the impact of patient selection and extended field radiation on relapse and survival. Of the 878 patients with stage I and II Hodgkin's disease, 521 with clinical stages I and II received radiation alone as the initial treatment. The actuarial survival for all stage I and II patients was 85.1% at 5 years and 76.2% at 10 years, and for clinically stages patients treated with radiation alone, 87.2 and 77.6%, respectively. The relapse-free rate (RFR) for all clinical stage I and II patients treated with radiotherapy (RT) alone was 70.1% at 5 years and 65.8% at 10 years. Significant prognostic factors for RFR and survival included age, stage and histology. In addition, the extent of radiation was identified as an independent prognostic factor for survival as well as for relapse. (Author)

    Full Text Available Aim: to develop a system of evaluation of liver failure stage in children based on the International classification of functioning, disability and health (ICF. Patients and methods: based on the retrospective analysis of 14 biochemical markers, characterizing hepatic role in proteins, lipids and carbohydrates metabolism, of 115 children without liver diseases, 15 children who died of liver failure and 220 patients with various hepatic disorders, being followed-up in the SCCH of RAMS, a score system of evaluation of liver failure stage in children as an additional diagnostic tool was developed. Each of the biochemical markers was assessed according to the 5-point rating scale in dependence of its changes intensity. Results: the sum of points was considered to be a criterion of liver failure stage. According to the ICF recommendations, decrease of points on 0–4% (54–56 points corresponds with absence of liver failure; 5–24% (43–53 points — as mild dysfunction, 25–49% (29–42 points — as moderate; 50-95% (3–28 points — as severe; and 96–100% (0-2 points — as absolute failure. Conclusions: score system of evaluation of liver failure stage can be applied at any step of diagnostics and treatment of children of any age, due to independence of the used markers from the age. It can be used in assessment of the severity of disorder in dynamics, in determination of the prognosis and as criterion of indications to liver transplantation, as well as during medico-social examination.

    Full Text Available Abstract Background Although evaluation of at least 12 lymph nodes (LNs is recommended as the minimum number of nodes required for accurate staging of colon cancer patients, there is disagreement on what constitutes an adequate identification of such LNs. Methods To evaluate the minimum number of LNs for adequate staging of Stage II and III colon cancer, 490 patients were categorized into groups based on 1-6, 7-11, 12-19, and ≥ 20 LNs collected. Results For patients with Stage II or III disease, examination of 12 LNs was not significantly associated with recurrence or mortality. For Stage II (HR = 0.33; 95% CI, 0.12-0.91, but not for Stage III patients (HR = 1.59; 95% CI, 0.54-4.64, examination of ≥20 LNs was associated with a reduced risk of recurrence within 2 years. However, examination of ≥20 LNs had a 55% (Stage II, HR = 0.45; 95% CI, 0.23-0.87 and a 31% (Stage III, HR = 0.69; 95% CI, 0.38-1.26 decreased risk of mortality, respectively. For each six additional LNs examined from Stage III patients, there was a 19% increased probability of finding a positive LN (parameter estimate = 0.18510, p Conclusions Thus, the 12 LN cut-off point cannot be supported as requisite in determining adequate staging of colon cancer based on current data. However, a minimum of 6 LNs should be examined for adequate staging of Stage II and III colon cancer patients.

    The design presented in this paper is in response to the revolution in private space activities, the increasing public interest in commercial flights to space and the utilization of structures such as space hotels or private orbital habitats. The baseline for the Omicron design concept is the Russian Salyut derived space station module. Salyut was the first space station to orbit the Earth. Its unique design and technical features were what made the development of space stations Salyut 1-7, MIR and the International Space Station (ISS) Zwezda service module possible. Due to its versatility and the reliable operating launch vehicle Proton, this space module series has the potential to be adapted for space hotel development. This paper proposes a conceptual design of the space habitat called Omicron, with particular focus on interior design for the microgravity environment. The Omicron concepts address the needs of space tourism with a strong emphasis on the safety and comfort of the spaceflight participants. The Omicron habitat supports three inhabitants in nominal conditions (e.g., two passengers and one astronaut). The habitat provides a flexible interior, facilities and spaces dynamically transforming in order to accommodate various types of activities, which will be performed in an organically formed interior supporting spatial orientation and movement in microgravity. The future development potential of Omicron is also considered. The baseline version is composed solely of one rigid module with an inverted cupola for observations. An alternative version offers more space using an inflatable structure. Finally, a combination of multiple Omicron modules enables the creation of a larger orbital habitat. The Omicron's subsystems support a few days visit by trained passengers. The transport to the habitat would be provided e.g., by the Soyuz TMA spacecraft carried by the Soyuz launch vehicle in the early stage of Omicron's development, before a fully reusable

    Seminoma represents about 60 % of all testicular germ cell tumors. At presentation about 80 % of patients have stage I and about 15 % have stage II disease. The last three decades have seen a substantial change in the philosophy of management with the success of surveillance as a strategy to minimize unnecessary treatment, recognition of the late effects of radiation therapy, and the success of cisplatin-based chemotherapy as curative treatment either in the first-line or salvage setting. Overall, in stage I disease where 80-85 % are cured with orchiectomy alone, efforts now are directed at reducing the burden of the disease and its diagnosis on patients with increasing utilization of surveillance and decreased employment of adjuvant therapy. For stage II disease, balancing the relative toxicities of radiation and chemotherapy while avoiding the use of multimodality therapy due to the additive long-term toxicity has become the priority.

    The decision to treat a patient with stage II colon cancer with adjuvant chemotherapy can be challenging. Although the benefit of treatment is clear in most patients with stage III disease, the decision to provide chemotherapy after surgical resection in stage II disease must be made on an individual basis. Several trials have demonstrated the small but absolute benefits of receiving adjuvant chemotherapy for stage II colon cancer for disease-free survival and overall survival. In an attempt to better understand the role of chemotherapy, several studies were performed that identified high-risk characteristics that can be used prognostically and predictively to aid in the clinical decision making process. ASCO, the National Comprehensive Cancer Network, and the European Society of Medical Oncology have published guidelines describing these high-risk characteristics. Since then, several other molecular markers have emerged that may offer more information on a given patient's risk for recurrence. The decision to treat a patient with stage II colon cancer must be made on an individual basis, considering the risks and benefits of treatment. In this short review, we will present the available evidence and offer possible directions for future study.

    2001-07-01

    For Stage II of the European Dioxin Project the following objectives were set: - Amendment of existing emission data collected for most relevant emission sources in order to reduce uncertainties of emission estimates. Collecting first emission data from countries not yet performing dioxin emission measurement programs. Extending the inventory of dioxin emissions to ambient air produced in Stage I by a complementary study on emissions to land and water. Extending the regional scope of data collection to countries in Central Europe. The report of Stage II of the European Dioxin Project is presented in 3 Volumes. Volume 1 contains an overview on the background and approach of different activities carried out and on the results obtained. These results are put into a broader view regarding the dioxin reduction measures in Europe leading to conclusions and recommendation for future work. Volume 2 of the report contains a detailed presentation of the sub-projects carried out. The chapters of Volume 2 are structured in a similar manner and start with a short summary in order to allow for a fast cross-reading. In the case of the desk-top studies an overview of the main results or statements is given. Regarding emission measurements details on the experimental set-up and the facilities being investigated are presented. Volume 3 contains a re-evaluation of the dioxin emission inventory presented for the most relevant sources types in the Stage I report. New data gathered from the projects of Stage II as well as from independent activities in the European countries are considered for a revision of the 1995 emission estimates. Additionally, based on current trends and activities the PCDD/F emissions for the years 2000 and 2005 are estimated. Finally, an attempt is made to evaluate the PCDD/F emission reduction rates which might be possible to achieve by the year 2005 compared to 1985. (orig.)

    From 1981 to 1988, 265 patients with breast cancer stages I and II (UICC-1987), were evaluated after conservative treatment with quadrantectomy plus axillectomy, radiotherapy and chemotherapy. After surgical treatment, the patients were submitted to radiation therapy in the breast. One hundred and fifty six (58,8%) patients were submitted to adjuvant chemotherapy. The median clinical follow-up period was 42.8 months with a minimum of 24 and a maximum of 99 months. Six (2,3%) patients presented local recurrence and 48 (18,1%) presented distant metastasis. After five years the total survival rate was 89,7% and the disease free survival rate was 75% in the same period. The study did not show significant differences among the clinical stages classified after surgery and the use of adjuvant chemotherapy did not influence the results of the many stages.

    74 cases of primary ovarian cancer treated here previously were classified into three groups, no residual (corresponding to Stage Ia, Ib), cell residual (Ic-IIc) and mass residual (III,IV), and prognoses were compared. The 5 year survival rates were 83.3%, 29.4% and 12.6% respectively. In Stage I and II cases, almost all of the tumor mass would be removed by operation. Therefore the target of postoperative treatment should be the residual cancer as cell units spread widely throughout the abdominal cavity. For this purpose, IPCP. has been performed on 35 cases of Stage I and II since 1977. The 3 year survival rate for this series is as good as 88.6%, and the sites of recurrence were localized in the small pelvic cavity adjacent to the Douglas pouch in 5 out of 6 relapsed cases. This fact suggests that IPCP is capable of controlling the cancer cells in the upper abdominal cavity, but still insufficient to control them in the pelvic cavity where deeper invasion is suspected. In order to improve the local control ability, utilization of the uterus as the applicator for prophylactic intracavitary irradiation came to be considered. The spread of cancer to the uterus was found in 5 out of 38 cases in Stage I and II(13.2%), but silent invasion was found in only one case. These results suggests that the utilization of the uterus as the applicator for prophylactic intracavitary irradiation would be feasible if no macroscopical cancer extention to the uterus exists and the uterus is suitable for application. Several combinations with Tandem and Ovoid have been tested and an adequate method has been proposed. (author)

    The AIM of this retrospective study is to analyse the indications and the results of treatment of endometrial carcinomas by preoperative radiotherapy. MATERIAL: From 1976 to 1995, 183 patients FIGO stage I or II were treated by preoperative radiotherapy consisting in 95 cases of external radiotherapy (XRT) and brachytherapy (BT) followed by surgery (S) and, in 88 cases of BT alone before surgery, XRT was indicated in cases of grade 2 or 3 and/or cervical involvement. METHODS: XRT was delivered with a 4-fields technique to 40 Gy in 20 fractions with a medial shielding at 30 Gy. BT was done with low dose rate Cs137 and Fletcher-Suit-Delclos applicators with two intra-uterine tubes and vaginal ovoieds. Complications were scored using the French-Italian syllabus. RESULTS: Five-year actuarial survival rates per stage are: Ia=91%, Ib=83%, II=71%, and per grade: G1=80%, G2=79%, G3=90%. Failures were pelvic in 5/183 (2.7%), vaginal in 4 cases (2%) and nodal in 2 cases (1%). Twelve patients developed metastases (6.5%). Complications were analysed during the radiotherapy, after the surgery and with unlimited follow-up. After BT/S, 12 grade 1, 1 grade 2 and 1 grade 3 complications were observed. In the group of patients treated by RT/BT/S, 22 grade 1, 11 grade 2, 4 grade 3 occurred. There is no statistical correlation between complications and parameters of treatment (XRT, hwt, HWT, reference dose to the bladder and rectum, dose rate of brachytherapy). SUMMARY: Preoperative irradiation is an effective and safe treatment of high risk stage I/II endometrial carcinomas. Results seem independent of the pathology grade

    Conclusions. The level of oral hygiene in patients of both groups was low due to incorrect selection of personal hygiene products or their untimely replacement. In patients with generalized periodontitis of II degree and stage II hypertension, the level of oral hygiene was lower than in somatically healthy persons: the worse status of oral cavity hygiene – the more pronounced changes in the periodontal tissues. We can suppose that high blood pressure affects the status of the oral cavity, creates a higher risk and exacerbates the periodontal diseases.

    The clinical and prognostic value of transcutaneous oxygen pressure measurements at rest has been established in Leriche Stage III and IV occlusive peripheral arterial disease but is controversial in Stage II because there is an overlap of transcutaneous pO2 (Tc pO2) values with those of normal subjects. The authors report the results of Tc pO2 measurements during exercise testing in a group of patients with Stage II occlusive arterial disease of the lower limbs. Seventy-eight patients with an average age of 53 years (range 40 to 65 years) whose claudication perimeter and site of pain had been carefully assessed and who had also recently undergone Doppler arterial examination and arteriography and 35 control subjects with an average age of 54 years (range 45 to 70 years) were studied. The Tc pO2 was continuously measured with a multimodular Kontron Supermon at 4 different sites simultaneously: precordium (reference probe), thigh, calf and foot in the dorsal recumbent position after 30 minutes rest, during a standardised exercise stress test at 50 watts and during the recovery phase. The results were expressed as ratio of tissue oxygenation (RTO): thigh, calf or foot Tc pO2/precordial Tc pO2 X 100 in order to take into account the patients cardiorespiratory status and adaptation to exercise. The RTO in normal subjects remained at the upper limits of the resting value throughout exercise and then returned slowly to basal values during the recovery phase.(ABSTRACT TRUNCATED AT 250 WORDS)

    The self-concept is composed through the interaction with others (Mead,1934). As selfconceptual study in early childhood, most targets the same age others. However, it is thought that the existence of the others at other stages of development brings the influence to the self-concept if the self-concept is composed by the interaction with others. The present study aimed to search for children's understanding of stages of human development and children's self-concept by the comparisons between ...

    Several clinical studies analyze axillary treatment in women with early-stage breast cancer because of changes in the indication for axillary lymph node dissection. The aim of the study is to analyze the impact of axillary radiotherapy in disease-free and overall survival in women with early breast cancer treated with lumpectomy. Retrospective study in women with initial stages of breast carcinoma treated by lumpectomy. A comparative analysis of high-risk women with axillary lymph node involvement who received axillary radiotherapy with the group of women with low risk without radiotherapy was performed. Logistic regression was used to determine factors influencing survival and lymphedema onset. A total of 541 women were included in the study: 384 patients (71%) without axillary lymph node involvement and 157 women (29%) with 1-3 axillary lymph node involvement. Patients with axillary radiotherapy had a higher number of metastatic lymph node compared to non-irradiated (1.6±0.7 vs. 1.4±0.6, P=.02). The group of women with axillary lymph node involvement and radiotherapy showed an overall and disease-free survival at 10 years similar to that obtained in patients without irradiation (89.7% and 77.2%, respectively). 3 lymph nodes involved multiplied by more than 7 times the risk of death (HR=7.20; 95% CI: 1.36 to 38.12). The multivariate analysis showed axillary lymph node dissection as the only variable associated with the development of lymphedema. The incidence of axillary relapse on stage I and II breast cancer is rare. In these patients axillary radiotherapy does not improve overall survival, but contributes to regional control in those patients with risk factors. Copyright © 2016 AEC.

    Considerable progress has been made in the prevention and treatment of pressure ulcers but they remain a significant healthcare problem, particularly among the elderly. Treatment may include the use of wound dressings such as hydrogels as well as debridement products that contain relatively high concentrations of various enzymes. Unlike enzymes found in debridement products, low concentrations of endopeptidase enzymes can cleave to denatured proteins. Many endopeptidases have been reported to enhance the healing process. To evaluate the effect of a hydrogel wound dressing containing a combination of endopeptidases on pressure ulcers, a 12-week prospective preliminary study was conducted involving 10 nursing home patients with Stage II (n = 3) or Stage III (n = 7) ulcers that had failed to respond to previous treatments. Seven subjects (three with Stage II ulcers and four with Stage III ulcers) completed the study. Healing was based on wound closure by re-epithelialization as determined by area measurement and clinical assessment. All three Stage II ulcers and two of the Stage III ulcers healed completely; four Stage III ulcers were categorized as healing (>60% improvement) after 12 weeks of care. No dressing-related adverse events occurred and subject acceptance of the product, including comfort, was high. These results suggest that additional studies designed to define the possible contribution of endopeptidase enzymes in wound healing are warranted.

    Difficult airway situations both expected and unexpected, present major challenges to every anesthesiologist, especially in pediatric anesthesia. However, the integration of extraglottic airway devices, such as the laryngeal mask, into the algorithm of difficult airways has improved the handling of difficult airway situations. A device for establishing a supraglottic airway, the laryngeal tube (LT), was introduced in 1999. The LT is an extraglottic airway designed to secure a patent airway during either spontaneous breathing or controlled ventilation. The design of the device has been revised several times and a further development is the LTS II/LTS-D, which provides an additional channel for the insertion of a gastric drain tube. This article reports on the successful use of the LTS II in 12 children aged from 2 days to 6 years when endotracheal intubation, alternative mask or laryngeal mask ventilation failed. Use of the LTS II was associated with a high level of success, securing the airway when other techniques had failed. The potential advantage of the LTS II over the standard LT is an additional suction port, which allows gastric tube placement and can be used as an indirect indicator of correct placement. With a modified insertion technique using an Esmarch manoeuvre, placement was simple and fast to perform. In emergency situations when direct laryngoscopy fails or is too time-consuming the LTS II tube is recommended as an alternative device to secure the airway. As with all extraglottic airway devices, familiarity and clinical experience with the respective device and the corresponding insertion technique are essential for safe and successful use, especially in emergency situations.

  18. Type II fatty acid synthesis is essential only for malaria parasite late liver stage development.

    Intracellular malaria parasites require lipids for growth and replication. They possess a prokaryotic type II fatty acid synthesis (FAS II) pathway that localizes to the apicoplast plastid organelle and is assumed to be necessary for pathogenic blood stage replication. However, the importance of FAS II throughout the complex parasite life cycle remains unknown. We show in a rodent malaria model that FAS II enzymes localize to the sporozoite and liver stage apicoplast. Targeted deletion of FabB/F, a critical enzyme in fatty acid synthesis, did not affect parasite blood stage replication, mosquito stage development and initial infection in the liver. This was confirmed by knockout of FabZ, another critical FAS II enzyme. However, FAS II-deficient Plasmodium yoelii liver stages failed to form exo-erythrocytic merozoites, the invasive stage that first initiates blood stage infection. Furthermore, deletion of FabI in the human malaria parasite Plasmodium falciparum did not show a reduction in asexual blood stage replication in vitro. Malaria parasites therefore depend on the intrinsic FAS II pathway only at one specific life cycle transition point, from liver to blood.

    Full Text Available Background: Around 30% of all stage II colon cancer patients will relapse and die of their disease. At present no objective parameters to identify high-risk stage II colon cancer patients, who will benefit from adjuvant chemotherapy, have been established. With traditional histopathological features definition of high-risk stage II colon cancer patients is inaccurate. Therefore more objective and robust markers for prediction of relapse are needed. DNA copy number aberrations have proven to be robust prognostic markers, but have not yet been investigated for this specific group of patients. The aim of the present study was to identify chromosomal aberrations that can predict relapse of tumor in patients with stage II colon cancer.

    Purpose: The present retrospective study assessed the role of proton beam therapy (PBT) in the treatment of patients with Stage II or III non-small-cell lung cancer who were inoperable or ineligible for chemotherapy because of co-existing disease or refusal. Patients and Methods: Between November 2001 and July 2008, PBT was given to 35 patients (5 patients with Stage II, 12 with Stage IIIA, and 18 with Stage IIIB) whose median age was 70.3 years (range, 47.4-85.4). The median proton dose given was 78.3 Gy (range, 67.1-91.3) (relative biologic effectiveness). Results: Local progression-free survival for Stage II-III patients was 93.3% at 1 year and 65.9% at 2 years during a median observation period of 16.9 months. Four patients (11.4%) developed local recurrence, 13 (37.1%) developed regional recurrence, and 7 (20.0%) developed distant metastases. The progression-free survival rate for Stage II-III patients was 59.6% at 1 year and 29.2% at 2 years. The overall survival rate of Stage II-III patients was 81.8% at 1 year and 58.9% at 2 years. Grade 3 or greater toxicity was not observed. A total of 15 patients (42.9%) developed Grade 1 and 6 (17.1%) Grade 2 toxicity. Conclusion: PBT for Stage II-III non-small-cell lung cancer without chemotherapy resulted in good local control and low toxicity. PBT has a definite role in the treatment of patients with Stage II-III non-small-cell lung cancer who are unsuitable for surgery or chemotherapy.

    Colorectal cancer (CRC) is the third most common cancer worldwide. Accurately identifying stage II CRC patients at risk for recurrence is an unmet clinical need. KCNQ1 was previously identified as a tumour suppressor gene and loss of expression was associated with poor survival in patients with CRC liver metastases. In this study the prognostic value of KCNQ1 in stage II and stage III colon cancer patients was examined. KCNQ1 mRNA expression was assessed in 90 stage II colon cancer patients (AMC-AJCCII-90) using microarray gene expression data. Subsequently, KCNQ1 protein expression was evaluated in an independent cohort of 386 stage II and stage III colon cancer patients by immunohistochemistry of tissue microarrays. Low KCNQ1 mRNA expression in stage II microsatellite stable (MSS) colon cancers was associated with poor disease-free survival (DFS) (P=0.025). Loss of KCNQ1 protein expression from epithelial cells was strongly associated with poor DFS in stage II MSS (PKCNQ1 seemed an independent prognostic value in addition to other high-risk parameters like angio-invasion, nodal stage and microsatellite instability-status. We conclude that KCNQ1 is a promising biomarker for prediction of disease recurrence and may aid stratification of patients with stage II MSS colon cancer for adjuvant chemotherapy.

    Colorectal cancer (CRC) is one of the leading causes of cancer deaths. Twenty-five percent of the patients radically treated for a stage II CRC (no lymph node or distant metastasis) later develop recurrence and dies from the disease. MicroRNAs (miRNAs) are aberrantly expressed or mutated in human...... cancers, and function either as tumour suppressors or oncogenes. Additionally, they also appear to have both diagnostic and prognostic significance. The aim of the present study was to identify miRNAs associated with recurrence of stage II CRC, followed up by an investigation of how these potential...... biomarkers functionally influence tumour cell behaviour. TaqMan® Human MicroRNA Array Set v2.0 was use to profile the expression of more than 600 miRNAs in 46 stage II CRC tumours (23 without recurrence and 23 with recurrence).

    In our center limited centro pelvic invasive carcinomas of the uterine cervix (less than 4 cm) are treated with brachytherapy and surgery. With these therapeutic modalities no residual carcinoma was observed for 80% of the patients. The purpose of this study was to evaluate our results with this treatment, and to evaluate the prognostic value of the pathological status of the cervix. From 1976 to 1987 we have treated 115 patients with these modalities. Staging system used was the FIGO classification modified for Stage II (divided in early Stage II and late Stage II). Patients were Stage IB (70 cases) and early Stage II (45 cases); 60 Gy were delivered with utero vaginal brachytherapy before any treatment. Six weeks later a radical hysterectomy with pelvic lymphadenectomy was performed. Twenty-one patients with positive nodes received a pelvic radiotherapy (45 to 55 Gy). Local control rate was 97% (100% for Stage IB and 93% for early Stage II). Uncorrected 10-year actuarial survival rate was 96% for Stage IB and 80% for early Stage II patients. No treatment failure was observed for Stage IB patients. Ninety-two patients (80%) had no residual carcinoma in the cervix (group 1) and 23 patients (20%) had a residual tumor (group 2). The sterilization rate of the cervix was 87% for Stage IB tumors versus 69% for early Stage II, and was 82% for N- patients versus 68% for N+ patients. Ten year actuarial survival rate was 92% for group 1 and 78% for group 2 (p = 0, 1). Grade 3 complications rate was 6%. We conclude that brachytherapy + surgery is a safe treatment for limited centro pelvic carcinomas of the uterine cervix (especially Stage IB) and that pathological status of the cervix after brachytherapy is not a prognostic factor

    The role of adjuvant chemotherapy for patients with stage II colon adenocarcinoma remains controversial. The high surgical cure rate for patients with "low-risk" stage II colon cancer, ranging from 75% to 80%, and the available clinical trials and meta-analyses provide conflicting recommendations for or against adjuvant chemotherapy for this group of patients. For fit "high-risk" stage II patients with clinical obstruction or perforation at presentation, in which the 5-year survival rate is 60% to 70%, there is little controversy, as these patients are routinely treated with adjuvant chemotherapy. Other potential high-risk factors, including high histologic grade, microsatellite instability, and loss of 18q, have yet to be validated in prospective trials. Patients with fewer than 12 regional lymph nodes identified in the surgical specimen have a statistically unclear risk of lymph node involvement. These patients may have stage III disease and should receive adjuvant therapy. The decision to use adjuvant chemotherapy to treat low-risk stage II colon cancer patients (no obstruction or perforation) should be an informed decision weighing the magnitude of a net 2% to 5% survival benefit, a 0.5% to 1.0% risk of mortality with chemotherapy in addition to 6 months of chemotherapy-related toxicities, other coexisting patient morbidities, and the anticipated life expectancy of each patient. As adjuvant chemotherapy is therapy addressing local or metastatic microscopic disease, and the effectiveness of systemic and biologically targeted therapy for advanced macroscopic colon cancer continues to improve rapidly, it remains to be determined by clinical trials whether therapies including newer agents such as cetuximab and bevacizumab administered in the adjuvant setting may affect survival for stage II cancer patients.

    The role of adjuvant radiation for Masaoka stages II and III thymoma remains controversial. The aim of this study was to evaluate the clinical benefit of radiation therapy for resected stages II and III thymoma patients. We retrospectively reviewed the medical records of 175 thymoma patients treated from July 1996 to January 2013 at University of Washington Medical Center; 88 patients with adequate follow-up and who met histologic criteria were included. We evaluated progression-free survival (PFS) and overall survival (OS), and compared these outcomes in patients treated by surgery (S) alone versus surgery plus radiotherapy (S+RT). Cox regression models and log-rank tests were used to compare PFS and OS for S versus S+RT, and they were further assessed by margin-positive versus margin-negative subgroups using Kaplan-Meier curves. Among the 88 thymoma patients, 22 were stage II and 18 were stage III. For all stages II and III patients, adjuvant radiation was not identified as a significant predictor for PFS (P=0.95) or OS (P=0.63). A positive surgical margin predicted for a worse OS (hazard ratio=7.1; P=0.004). Further investigation revealed for resection margin-positive patients; S+RT had higher OS than S alone (P=0.006). For stages II and III thymoma, postoperative adjuvant radiation was not associated with statistically significant differences in PFS or OS in this study. Our results indicated a potential OS benefit of adjuvant RT in patients with positive resection margins, and therefore may be considered in this patient population.

    Purpose Role of adjuvant radiation for Masaoka stage II and III thymoma remains controversial. The aim of this study was to evaluate the clinical benefits of radiation therapy for resected stages II and III thymoma. Methods and Materials We retrospectively reviewed the medical records of 175 thymoma patients treated from July 1996 to January 2013 at University of Washington Medical Center; 88 patients with adequate follow-up and who met histologic criteria were included. We evaluated progression-free survival (PFS) and overall survival (OS), and compared these outcomes in patients treated by surgery (S) alone versus surgery plus radiotherapy (S + RT). Cox regression models and log-rank tests were used to compare PFS and OS for S versus S + RT, and they were further assessed by margin-positive versus margin-negative subgroups using Kaplan-Meier curves. Results Among the 88 thymoma patients, 22 were stage II and 18 were stage III. For all stages II and III patients, adjuvant radiation was not identified as a significant predictor for PFS (P = 0.95) or OS (P = 0.63). A positive surgical margin predicted for a worse OS (hazard ratio = 7.1; P = 0.004). Further investigation revealed for resection margin-positive patients; S + RT had higher OS than S alone (P = 0.006). Conclusions For stages II and III thymoma, postoperative adjuvant radiation was not associated with statistically significant differences in PFS or OS in this study. Our results indicated a potential OS benefit of adjuvant RT in patients with positive resection margins, and therefore may be considered in this patient population. PMID:24517958

    From 1981 to 1988, 265 patients with breast cancer stages I and II (UICC-1987), were evaluated after conservative treatment with quadrantectomy plus axillectomy, radiotherapy and chemotherapy. After surgical treatment, the patients were submitted to radiation therapy in the breast. One hundred and fifty six (58,8%) patients were submitted to adjuvant chemotherapy. The median clinical follow-up period was 42.8 months with a minimum of 24 and a maximum of 99 months. Six (2,3%) patients presented local recurrence and 48 (18,1%) presented distant metastasis. After five years the total survival rate was 89,7% and the disease free survival rate was 75% in the same period. The study did not show significant differences among the clinical stages classified after surgery and the use of adjuvant chemotherapy did not influence the results of the many stages.

    Full Text Available This study was designed to investigate the expression of the T-box transcription factor 4 (TBX4, a tumor biomarker that was previously identified by proteomics, in pancreatic ductal adenocarcinoma (PDAC and evaluate its clinical utility as a potential prognostic biomarkers for PDAC. The expression of TBX4 was detected in 77 stage II PDAC tumors by immunohistochemistry, and the results were analyzed with regard to clinicopathological characteristics and overall survival. Moreover, Tbx4 promoter methylation status in primary PDAC tumors and normal adjacent pancreas tissues was measured by bisulfite sequencing. Among 77 stage II PDAC tumors, 48 cases (62.3% expressed TBX4 at a high level. No significant correlation between TBX4 expression and other clinicopathological parameters, except tumor grade and liver metastasis recurrence, was found. The survival of patients with TBX4-high expression was significantly longer than those with TBX4-low expression (P = 0.010. In multivariate analysis, low TBX4 expression was an independent prognostic factor for overall survival in patients with stage II PDAC. TBX4 promoter methylation status was frequently observed in both PDAC and normal adjacent pancreas. We conclude that a low level of TBX4 expression suggests a worse prognosis for patients with stage II PDAC. Down-regulation of the TBX4 gene in pancreas is less likely to be regulated by DNA methylation.

    Clinical and pathological indicators are inadequate for prognosis of stage II and III colorectal carcinoma (CRC). In this study, we utilized the activity of regulatory factors, univariate Cox regression and random forest for variable selection and developed a multivariate Cox model to predict the overall survival of Stage II/III colorectal carcinoma in GSE39582 datasets (469 samples). Patients in low-risk group showed a significant longer overall survival and recurrence-free survival time than those in high-risk group. This finding was further validated in five other independent datasets (GSE14333, GSE17536, GSE17537, GSE33113, and GSE37892). Besides, associations between clinicopathological information and risk score were analyzed. A nomogram including risk score was plotted to facilitate the utilization of risk score. The risk score model is also demonstrated to be effective on predicting both overall and recurrence-free survival of chemotherapy received patients. After performing Gene Set Enrichment Analysis (GSEA) between high and low risk groups, we found that several cell-cell interaction KEGG pathways were identified. Funnel plot results showed that there was no publication bias in these datasets. In summary, by utilizing the regulatory activity in stage II and III colorectal carcinoma, the risk score successfully predicts the survival of 1021 stage II/III CRC patients in six independent datasets.

    The role of adjuvant chemotherapy in patients with stage II colon cancer remains to be elucidated and its use varies between patients and institutions. Currently, clinical guidelines suggest discussing adjuvant chemotherapy for patients with high-risk stage II disease in the absence of conclusive randomized controlled trial data. To further investigate this relationship, the objective of the current study was to determine whether an association exists between overall survival (OS) and adjuvant chemotherapy in patients stratified by age and pathological risk features. Data from the National Cancer Data Base were analyzed for demographics, tumor characteristics, management, and survival of patients with stage II colon cancer who were diagnosed from 1998 to 2006 with survival information through 2011. Pearson Chi-square tests and binary logistic regression were used to analyze disease and demographic data. Survival analysis was performed with the log-rank test and Cox proportional hazards regression modeling. Propensity score weighting was used to match cohorts. Among 153,110 patients with stage II colon cancer, predictors of receiving chemotherapy included age clinically relevant OS was associated with the receipt of adjuvant chemotherapy in all patient subgroups regardless of high-risk tumor pathologic features (poor or undifferentiated histology, colon cancer evaluated to date, improved OS was found to be associated with adjuvant chemotherapy regardless of treatment regimen, patient age, or high-risk pathologic risk features.

    Full Text Available Aims. To evaluate the prognostic significance of serum interleukin-6 (IL-6 in colorectal cancer (CRC. Patients and Methods. Preoperative serum IL-6 was measured in 233 CRC patients and 13 healthy controls. Relationships between IL-6 and various clinicopathological factors were evaluated, and the overall survival (OS and disease-free survival (DFS rates according to IL-6 status were calculated for all patients and according to disease stage. Results. The mean IL-6 level was 6.6 pg/mL in CRC patients and 2.6 pg/mL in healthy controls. Using a cutoff of 6.3 pg/mL, obtained using receiver operating characteristic curve analysis, 57 patients had a high IL-6 level. The mean value was higher for stage II disease than for stage III disease. IL-6 status correlated with C-reactive protein (CRP and carcinoembryonic antigen levels, obstruction, and pT4 disease. The OS differed according to the IL-6 status for all patients, whereas the DFS differed for all patients and for those with stage II disease. The Cox proportional hazards model showed that pT4 disease was an independent risk factor for recurrence in all CRC patients; IL-6, CRP, and pT4 were significant risk factors in stage II patients. Conclusions. The preoperative IL-6 level influences the risk of CRC recurrence.

    Despite complete resection of the early stage of oral tongue cancer by partial glossectomy, late cervical lymph node metastasis is frequently observed. Gene amplification of ACTN4 (protein name: actinin-4) is closely associated with the metastatic potential of various cancers. This retrospective study was performed to demonstrate the potential usefulness of ACTN4 gene amplification as a prognostic biomarker in patients with stage I/II oral tongue cancer. Fifty-four patients with stage I/II oral tongue cancer were enrolled retrospectively, in accordance with the reporting recommendations for tumour marker prognostic studies (REMARK) guidelines. The copy number of ACTN4 and the protein expression of actinin-4 were evaluated by fluorescence in situ hybridization (FISH) and immunohistochemistry (IHC), respectively. The overall survival time of patients with gene amplification of ACTN4 was significantly shorter than that of patients without gene amplification (P=0.0010, log-rank test). Gene amplification of ACTN4 was a significant independent risk factor for death in patients with stage I/II oral tongue cancer (hazard ratio 6.08, 95% confidence interval 1.66-22.27). Gene amplification of ACTN4 is a potential prognostic biomarker for overall survival in oral tongue cancer. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Full Text Available AIM: To evaluate the effect of intravitreal ranibizumab injection for retinopathy of prematurity (ROP in Zone II Stage 3+. METHODS: Data was collected for ROP patients with Zone II Stage 3+ who received intravitreal ranibizumab injections between October 2014 and Janu­ary 2017 at the Department of Ophthalmology in our hospital. No prior laser or other intravitreal treatment was done. Prior to the intervention and at each follow-up visit, fundus examination was performed. Gestational age at birth, sex, birth weight, ROP zone, ROP stage, post menstrual age (PMA at treatment, and follow-up pe­riod were recorded. The final clinical status of the retina was evaluated for each patient. The primary outcome mea­sures included ROP recurrences requiring re-treatment, complete or incomplete peripheral vascularization. RESULTS: Eighty-six eyes of 46 premature infants with Zone II Stage 3+ ROP were enrolled in the study. The mean gestational age at birth was 28.18±1.67 (range: 25 to 33wk and the mean birth weight was 1070.57±226.85 (range: 720.00 to 1650.00 g. The mean PMA at treatment was 38.32±2.99 (range: 32.29 to 46.00wk. Seventy-one eyes (82.56% were treated success­fully with intravitreal ranibizumab as monotherapy. Fifteen eyes (17.44% developed recurrent disease. The mean interval between the treatment and retreatment was 5.96±3.22 (range: 1.86 to 11.71wk. All eyes vascularized into zone III at the end of the study and among them 62 eyes (72.09% achieved complete vascu­larization. CONCLUSION: Intravitreal ranibizumab injection is an effective treatment in Zone II Stage 3+ ROP patients. More patients with longer follow-up duration are necessary to confirm the safety and efficacy of this treatment.

  9. Stage II Chronic Maxillary Atelectasis Associated with Subclinical Visual Field Defect

    2013-09-01

    Full Text Available Introduction: Chronic maxillary atelectasis (CMA is characterized by a persistent decrease in the maxillary sinus volume due to inward bowing of its walls. According to its severity, it may be classified into three clinical-radiological stages. Objective: To report a case of stage II CMA associated with subclinical visual field defect. Case Report: A 34-year-old woman presented with a 15-year history of recurrent episodes of sinusitis and intermittent right facial discomfort for the past 5 years. She denied visual complaints, and no facial deformities were observed on physical examination. Paranasal sinus computed tomography (CT demonstrated a completely opacified right maxillary sinus with inward bowing of its walls, suggesting the diagnosis of stage II CMA. A computerized campimetry (CC disclosed a scotoma adjacent to the blind spot of the right eye, indicating a possible damage to the optic nerve. The patient was submitted to functional endoscopic sinus surgery, with drainage of a thick mucous fluid from the sinus. She did well after surgery and has been asymptomatic since then. Postoperative CT was satisfactory and CC was normal. Discussion: CMA occurs because of a persistent ostiomeatal obstruction, which creates negative pressure inside the sinus. It is associated with nasosinusal symptoms but had never been described in association with any visual field defect. It can be divided into stage I (membranous deformity, stage II (bony deformity, and stage III (clinical deformity. The silent sinus syndrome is a special form of CMA. This term should only be used to describe those cases with spontaneous enophthalmos, hypoglobus, and/or midfacial deformity in the absence of nasosinusal symptoms.

  10. A Bayesian predictive strategy for an adaptive two-stage design in phase II clinical trials.

    Phase II clinical trials are typically designed as two-stage studies, in order to ensure early termination of the trial if the interim results show that the treatment is ineffective. Most of two-stage designs, developed under both a frequentist and a Bayesian framework, select the second stage sample size before observing the first stage data. This may cause some paradoxical situations during the practical carrying out of the trial. To avoid these potential problems, we suggest a Bayesian predictive strategy to derive an adaptive two-stage design, where the second stage sample size is not selected in advance, but depends on the first stage result. The criterion we propose is based on a modification of a Bayesian predictive design recently presented in the literature (see (Statist. Med. 2008; 27:1199-1224)). The distinction between analysis and design priors is essential for the practical implementation of the procedure: some guidelines for choosing these prior distributions are discussed and their impact on the required sample size is examined.

    It remains controversial whether patients with Stage II colorectal cancer would benefit from adjuvant chemotherapy after radical resection. The aim of this study was to establish two mathematical models to identify the suitable patients for adjuvant chemotherapy. The current study comprised of two steps. In the first step, 353 patients with Stage II colorectal cancer who underwent surgical procedures at the Third Affiliated Hospital of Sun Yat-sen University between June 2006 and December 2015 were entered and followed up for 6-120 months. Their clinical data were collected and enrolled into the database. We established two mathematical models by univariate and multivariate Cox regression analysis to identify the target patients; in the second step, 230 patients under the same standard between January 2012 and December 2016 were entered and followed up for 3-62 months to verify the two models' validation. In the first step, totally 340 surgical patients with Stage II colorectal cancer were finally enrolled in this study. Statistical analysis showed that tumor differentiation (TD) (P models: (1) OS risk score = 1.116 × TD + 2.202 × LVI + 3.676 × UPM + 1.438 × LN - 0.493; (2) DFS risk score = 0.789 × TD + 2.074 × LVI + 3.183 × UPM + 1.329 × LN - 0.432. According to the models and cutoff points [(0.07, 1.33) and (-0.04, 1.30), respectively], patients can be divided into three groups: low-risk, moderate-risk, and high-risk. Moreover, the high-risk group patients could benefit from adjuvant chemotherapy. In the second step, totally 221 patients were finally used to verify the models' validation. The results proved that the models were accurate and feasible (Ppredictive models, patients with Stage II colorectal cancer in the high-risk group are strongly recommended for adjuvant chemotherapy, thus facilitating the individualized and precise treatment.

  12. Resistance Torque Based Variable Duty-Cycle Control Method for a Stage II Compressor

    2017-07-01

    The resistance torque of a piston stage II compressor generates strenuous fluctuations in a rotational period, and this can lead to negative influences on the working performance of the compressor. To restrain the strenuous fluctuations in the piston stage II compressor, a variable duty-cycle control method based on the resistance torque is proposed. A dynamic model of a stage II compressor is set up, and the resistance torque and other characteristic parameters are acquired as the control targets. Then, a variable duty-cycle control method is applied to track the resistance torque, thereby improving the working performance of the compressor. Simulated results show that the compressor, driven by the proposed method, requires lower current, while the rotating speed and the output torque remain comparable to the traditional variable-frequency control methods. A variable duty-cycle control system is developed, and the experimental results prove that the proposed method can help reduce the specific power, input power, and working noise of the compressor to 0.97 kW·m-3·min-1, 0.09 kW and 3.10 dB, respectively, under the same conditions of discharge pressure of 2.00 MPa and a discharge volume of 0.095 m3/min. The proposed variable duty-cycle control method tracks the resistance torque dynamically, and improves the working performance of a Stage II Compressor. The proposed variable duty-cycle control method can be applied to other compressors, and can provide theoretical guidance for the compressor.

    Free-radical oxidation was studied in 40 patients with hypertension stage II. The oxidation was found activated as blood and red cell levels of dien, trien conjugates, malon dialdehyde increased. The antioxidant protection was depressed: catalase, glutathione reductase activity reduced as did alpha-tocopherol deposits. This led to a growth of cerebral BB-creatine phosphatase and, consequently, to impairment of cerebral membranes.

    The circadian timing system has a rhythm and one of the roles of this system is the mediation of hormonal and metabolic adaptations to lactation. This study was conducted to determine whether the time to stage II lactogenesis differed in women who underwent cesarean section (CS) in the daytime (DT) or night-time (NT). This study was conducted at Süleymaniye Research and Education Hospital between June and December 2016. Two hundred and eighty-eight mothers who had a cesarean delivery and their healthy singleton neonates were included. Clinical and demographic data of the mothers and neonates, time of initiation of breastfeeding and time to stage II lactogenesis were analyzed according to DT or NT CS groups. There were no statistically significant differences in age, gravida, parity, body mass index, week of gestation at birth, postoperative hemoglobin level, cesarean indications, anesthesia type, previous history of breastfeeding, transfusion need, Apgar scores or birth weight-height of neonates between the DT and NT CS groups. While the time of initiation of breastfeeding did not differ statistically in terms of DT or NT CS groups, the time to stage II lactogenesis was significantly longer in the NT CS group. NT cesarean delivery is a risk factor for the delayed onset of lactogenesis. The results of this study may be useful to clinical practitioners counseling mothers who undergo NT cesarean delivery. © 2018 Japan Society of Obstetrics and Gynecology.

    The role of clusterin in tumor growth and progression remains unclear. Overexpression of cytoplasmic clusterin has been studied in aggressive colon tumors; however, no correlation between clusterin expression and survival in colorectal cancer has been identified to date. We assessed levels of clusterin expression in a group of stage II colorectal cancer patients to assess its utility as a prognostic marker. The study included 251 patients with stage II colorectal cancer. Tissue microarrays were constructed and immunohistochemistry done and correlated with clinical features and long term outcome. Dual immunofluorescence and confocal microscopy were used with terminal deoxynucleotidyl-transferase-mediated dUTP nick-end labeling probes and clusterin antibody to assess the degree of co localization. Percentage epithelial cytoplasmic staining was higher in tumor compared with nonadjacent normal mucosa (P < 0.001). Within the stromal compartment, percentage cytoplamic staining and intensity was lower in tumor tissue compared with normal nonadjacent mucosa (P < or = 0.001). Survival was significantly associated with percentage epithelial cytoplasmic staining (P < 0.001), epithelial cytoplasmic staining intensity (P < 0.001), percentage stromal cytoplasmic staining (P = 0.002), and stromal cytoplasmic staining intensity (P < 0.001). Clusterin levels are associated with poor survival in stage II colorectal cancer.

    Full Text Available BACKGROUND: Cancer stem cells (CSCs are a subset of tumor cells with capacity to self-renew and generate the diverse cells that make up the tumor. The aim of this study is to evaluate the prognostic value of CSCs in a highly homogeneous population of stage II colon cancer. METHODS: One hundred stage II colon cancer patients treated by the same surgical team between 1977 and 2005 were retrospectively analyzed. None of the patients received adjuvant chemotherapy. Inmunohistochemistry expression of CD133, NANOG and CK20 was scored, using four levels: 50% positivity. Kaplan-Meier analysis and log rank test were used to compare survival. RESULTS: The average patient age was 68 years (patients were between 45-92 years of age and median follow up was 5.8 years. There was recurrent disease in 17 (17%; CD133 expression (defined by >10% positivity was shown in 60% of the tumors, in 95% for NANOG and 78% for CK20. No correlation was found among expression levels of CD133, NANOG or CK20 and relapse-free survival (RFS or overall survival (OS. However, a statistical significant correlation was found between established pathological prognostic factors and RFS and OS. CONCLUSIONS: Stem Cell quantification defined by CD133 and NANOG expression has no correlation with RFS or OS in this cohort of Stage II colon cancer.

  17. Analyzing proteasomal subunit expression reveals Rpt4 as a prognostic marker in stage II colorectal cancer.

    LENUS (Irish Health Repository)

    2012-02-01

    Colorectal cancer is a leading cause of cancer-related deaths worldwide. Early diagnosis and treatment of colorectal cancer is the key to improving survival rates and as such a need exists to identify patients who may benefit from adjuvant chemotherapy. The dysregulation of the ubiquitin-proteasome system (UPS) has been implicated in oncogenesis and cancer cell survival, and proteasome inhibitors are in clinical use for a number of malignancies including multiple myeloma. In our study, we examined the protein expression of several key components of the UPS in colorectal cancer using immunohistochemistry to determine expression levels of ubiquitinylated proteins and the proteasomal subunits, 20S core and Rpt4 in a cohort of 228 patients with colon cancer. Multivariate Cox analysis revealed that neither the intensity of either ubiquitinylated proteins or the 20S core was predictive in either Stage II or III colon cancer for disease free survival or overall survival. In contrast, in Stage II patients increased Rpt4 staining was significantly associated with disease free survival (Cox proportional hazard ratio 0.605; p = 0.0217). Our data suggest that Rpt4 is an independent prognostic variable for Stage II colorectal cancer and may aid in the decision of which patients undergo adjuvant chemotherapy.

    Juvenile osteochondritis dissecans (OCD) has a better prognosis than the adult type. We postulated that the excellent prognosis of juvenile OCD could be explained, at least in part, by the erroneous diagnosis of some developmental variants of ossification as stage-I OCD. Knee MRIs of 38 children, ages 7.5-17.7 years (mean and median age 13 years), were retrospectively reviewed to look for features that might separate normal variants of ossification from stage-I OCD. These included age, gender, site, configuration of the lesion, residual cartilaginous model and presence of edema. Twenty-three patients (32 condyles) had ossification defects with intact articular cartilage suggestive of stage-I lesions. No stage-II lesions were seen in the posterior femoral condyles. Accessory ossification centers were seen in 11/16 posterior condyles and 3/16 central condyles. Spiculation of existing ossification was seen in 12/16 posterior condylar lesions and 1/16 central condyles. There was a predominance of accessory ossifications and spiculations in the patients with 10% or greater residual cartilaginous model. No edema signal greater than diaphyseal red-marrow signal was seen in the posterior condyles. Clinical follow-up ranged from 0.5 to 38 months, with clinical improvement in 22 out of 23 patients. Inclusion of normal variants in the stage-I OCD category might explain, in part, the marked difference in published outcome between the juvenile and adult forms of OCD. Ossification defects in the posterior femoral condyles with intact overlying articular cartilage, accessory ossification centers, spiculation, residual cartilaginous model, and lack of bone-marrow edema are features of developmental variants rather than OCD.

    A retrospective analysis was done for 69 patients with Stage I and II non-Hodgkin lymphoma who were treated from May 1981 to December 1990, in the Department of Radiadtion Oncology, Korea University Hospital. We used Ann Arbor Staging system and Working Formulation for histological classification. Forty-three patients(43/69, 62.3%) were Stage I and 26 patients (26/69, 37.7%) were Stage II, and B symptom was found in 10.1%(7/69). Local control rate for all patients was 88.4%(61/69), with 80% (12/15) for nodal lymphoma and 90.7%(49/54) for extra nodal lymphoma. The total failure rate was 34.8%(24/69). Five of 24 (20.8%) patients who were failed developed local failure only, 12.5%(3/24) local failure with distant failure, and distant failure only were found in 66.7%(16/24). Between nodal lymphoma and extra nodal lymphoma, there was no significant survival difference, but extra nodal lymphoma showed higher incidence

    Mucopolysaccharidosis (MPS) diseases lead to a profound disruption in normal mechanisms of growth and development. This study was undertaken to determine the general growth of children with MPS I and II. The anthropometric data of patients with MPS I and II (n=76) were retrospectively analyzed. The growth patterns of these patients were analyzed and then plotted onto Polish reference charts. Longitudinal analyses were performed to estimate age-related changes. At the time of birth, the body length was greater than reference charts for all MPS groups (Hurler syndrome, P=0.006; attenuated MPS II, P=0.011; severe MPS II, Pgrowth patterns for all patients were similar. Afterwards, these growth patterns start to differ for individual groups. The body height below the 3rd percentile was achieved around the 30th month for boys with Hurler syndrome, between the 4th and 5th year for patients with severe MPS II and between the 7th and 8th year for patients with attenuated MPS II. The growth pattern differs between patients with MPS I and II. It reflects the clinical severity of MPS and may assist in the evaluation of clinical efficacy of available therapies.

    Src belongs to a family of cytoplasmic tyrosine kinases that play a key role in tumor initiation and progression. Src activation has been associated with a more aggressive neoplastic phenotype and induces resistance to platinum agents in preclinical models. The aim of our study was to assess the prognostic and/or predictive value of Src activation in patients with stage II-III colon cancer. pSrc expression was assessed in paraffin-embedded tumor samples by immunohistochemistry (phospho-Y418, ab4816; Abcam). Cases were classified by staining intensity in 4 categories: no staining (0), weak (1+), moderate (2+), and intense (3+) staining. A total of 487 patients were evaluated (240 stage II, 247 stage III), of whom 298 (61%) had received adjuvant chemotherapy. Staining was absent in 78 (16%), weak in 262 (54%), moderate in 103 (21%), and intense in 44 (9%). High pSrc expression was significantly associated with decreased 5-year disease-free survival (39% versus 63% for patients with high versus low pSrc expression; hazard ratio, 0.56; P=.005) and overall survival (58% versus 74%; hazard ratio, 0.55; P=.02). Multivariate analysis confirmed pSrc expression as a significant prognostic factor both for disease-free survival and overall survival, independent of age, sex, tumor stage, bowel obstruction/perforation, or adjuvant chemotherapy. These findings illustrate the relevance of Src activation in colon cancer biology, conferring a poor prognosis to patients with early stage colon cancer regardless of adjuvant chemotherapy. Our findings may help improve prognostic stratification of patients for clinical decisions and open new avenues for potential pharmacologic manipulation that may eventually improve patients' outcomes.

    Stage for stage, rectal cancer has historically been associated with inferior survival compared with colon cancer. Randomized trials of rectal cancer have generally demonstrated improvements in locoregional relapse but not survival. We compared therapy and outcomes of colon versus rectal cancer in 2 time cohorts to determine if relative improvements have occurred. Patients with resected stage II/III colorectal cancer referred to the British Columbia Cancer Agency in 1989/1990 and 2001/2002 were identified. The higher of clinical or pathologic stage was used for patients receiving preoperative chemoradiation. Disease-specific survival (DSS) and overall survival (OS) were compared for rectal and colon cancer between the 2 cohorts. Kaplan-Meier method was used for survival analysis. A total of 1427 patients were included, with 375 from 1989/1990 and 1052 from 2001/2002. Between 1989/1990 and 2001/2002 there were significant increases in the use of perioperative chemotherapy for both rectal and colon cancer (Prectal cancer. DSS significantly improved for rectal (Pcolon cancer (P=0.069). Five-year OS was significantly inferior for rectal versus colon cancer in 1989/1990 (46.1% vs. 57.2%, P=0.023) and was similar to that of colon cancer in 2001/2002 (63.7% vs. 66.2%, P=0.454). Advances in locoregional and systemic therapy significantly improved survival among patients with rectal cancer. DSS and OS are now similar between colon and rectal cancer for both stage II and III disease.

    Full Text Available Colorectal cancer (CRC is one of the leading causes of cancer mortality. Metastasis remains the primary cause of CRC death. Predicting the possibility of metastatic relapse in early-stage CRC is of paramount importance to target therapy for patients who really need it and spare those with low-potential of metastasis. Ninety-six stage II CRC cases were stratified using high-resolution array comparative genomic hybridization (aCGH data based on a predictive survival algorithm and supervised clustering. All genes included within the resultant copy number aberrations were each interrogated independently at mRNA level using CRC expression datasets available from public repositories, which included 1820 colon cancers, and 167 normal colon tissues. Reduced mRNA expression driven by copy number losses and increased expression driven by copy number gains revealed 42 altered transcripts (29 reduced and 13 increased transcripts associated with metastatic relapse, short disease-free or overall survival, and/or epithelial to mesenchymal transition (EMT. Resultant genes were classified based on gene ontology (GO, which identified four functional enrichment groups involved in growth regulation, genomic integrity, metabolism, and signal transduction pathways. The identified 42 genes may be useful for predicting metastatic relapse in stage II CRC. Further studies are necessary to validate these findings.

    Purpose : To analyze survival rate and late rectal and bladder complication for patients with stage with stage I and II carcinoma of uterine cervix treated by radiation alone or combined with chemotherapy. Materials and Methods : Between November 1984 and December 1993, 127 patients with stage I and II carcinoma of uterine cervix treated by radiation alone or combined therapy of radiation and chemotherapy. Retrospective analysis for survival rate was carried out on eligible 107 patients and review for complication was possible in 91 patients. The median follow-up was 47 months (range 3-118) and the median age of patients was 56 years (range 31-76). 26 patients were stage IB by FIGO classification. 40 were stage IIA and 41 were stage IIB. 86 cases were treated by radiation alone and 21 were treated by radiation and chemotherapy. 101 patients were treated with intracavitary radiation therapy (ICRT), of these, 80 were received low dose rate (LDR) ICRT and 21 were received high dose rate (HDR) ICRT. Of the patients who received LDR ICRT, 63 were treated by 1 intracavitary insertion and 17 were underwent 2 insertions. And we evaluated the external radiation dose and midline shield. Results : Acturial survival rate at 5 years was 92% for stage IB, 75% for stage IIA, 53% for stage IIB and 69% in all patients. Grade 1 rectal complications were developed in 20 cases(22%), grade 2 were in 22 cases (24%), 22 cases (24%) of grade 1 urinary complications and 17 cases (19%) of grade 2 urinary complications were observed But no patients had severe complications that needed surgical management or admission care. Maximum bladder dose for the group of patients with urinary complications was higher than that for the patients without urinary complications(7608cGy v 6960cGy, p<0.01). Maximum rectal dose for the group of patients with rectal complications was higher than that for the patients without urinary complications (7041cGy v 6269cGy, p<0.01).

    Purpose: To determine whether patients with Masaoka stage II thymoma benefit from adjuvant radiation therapy after complete tumor resection. Methods and Materials: A total of 107 patients with stage II thymoma who underwent complete resection of their tumors between September 1964 and October 2006 were retrospectively analyzed. Sixty-six patients were treated with adjuvant radiotherapy, and 41 patients received surgery alone. Results: Eight patients (7.5%) had a relapse of their disease, including two patients (4.5%) who had surgery alone, and 6 patients (9.5%) who had adjuvant radiation therapy. Disease-free survival rates at 5 and 10 years were 92.3% and 82.6%, respectively, for the surgery-plus-radiation group, and 97.6% and 93.1%, respectively, for the group that underwent surgery alone (p = 0.265). Disease-specific survival rates at 5 and 10 years were 96.4% and 89.3%, respectively, for the surgery-plus-radiation group and 97.5% and 97.5% for the surgery group (p = 0.973). On univariate analysis, patients with type B3 thymomas had the lowest disease-free survival rates among all subtypes (p = 0.001), and patients with large thymomas (>7 cm) had lower disease-specific survival rates than those with small tumors (<7 cm) (p = 0.017). On multivariate analysis, histological type (type B3) thymoma was a significant independent prognostic factor. Conclusions: Adjuvant radiotherapy after complete tumor resection for patients with stage II thymoma did not significantly reduce recurrence rates or improve survival rates. Histological type (type B3) thymoma was a significant independent prognostic factor. Further investigation should be carried out using a multicenter randomized or controlled study.

  11. Statistical issues for design and analysis of single-arm multi-stage phase II cancer clinical trials.

    Phase II trials have been very widely conducted and published every year for cancer clinical research. In spite of the fast progress in design and analysis methods, single-arm two-stage design is still the most popular for phase II cancer clinical trials. Because of their small sample sizes, statistical methods based on large sample approximation are not appropriate for design and analysis of phase II trials. As a prospective clinical research, the analysis method of a phase II trial is predetermined at the design stage and it is analyzed during and at the end of the trial as planned by the design. The analysis method of a trial should be matched with the design method. For two-stage single arm phase II trials, Simon's method has been the standards for choosing an optimal design, but the resulting data have been analyzed and published ignoring the two-stage design aspect with small sample sizes. In this article, we review analysis methods that exactly get along with the exact two-stage design method. We also discuss some statistical methods to improve the existing design and analysis methods for single-arm two-stage phase II trials. Copyright © 2015 Elsevier Inc. All rights reserved.

    Since one third of the patients with Stage II endometrial carcinoma have occult extrauterine pelvic metastases at diagnosis, adequate treatment must include the pelvic lymph nodes and parametria. Eighty-three patients with Stage II endometrial carcinoma were treated between January 1964 and December 1983. Sixty-nine patients (83%) received combined whole-pelvic irradiation and surgery, five (6%) had surgery alone and nine (11%) had radiotherapy alone. Five-year actuarial survival rates were 67%, 60%, and 38%, respectively. No pelvic recurrence occurred in the 69 patients who received the combined therapy, and there was no vaginal recurrence in the 80 patients treated with intracavity radium. There was a significantly lower incidence of pelvic lymph node metastases (P = 0.03) in patients treated with preoperative irradiation. The median time to recurrence was 17 months, with 67% of the recurrences diagnosed before 2 years, and 88% within 5 years. Ten patients (12%) incurred severe complications and three died as a result. Whole-pelvic irradiation, intracavity radium, and hysterectomy are effective treatment for occult pelvic and vaginal disease

    The clinical behaviour of colon cancer is heterogeneous. Five-year overall survival is 50-65% with all stages included. Recurring somatic chromosomal alterations have been identified and some have shown potential as markers for dissemination of the tumour, which is responsible for most colon cancer deaths. We investigated 115 selected stage II-IV primary colon cancers for associations between chromosomal alterations and tumour dissemination. Follow-up was at least 5 years for stage II-III patients without distant recurrence. Affymetrix SNP 6.0 microarrays and allele-specific copy number analysis were used to identify chromosomal alterations. Fisher's exact test was used to associate alterations with tumour dissemination, detected at diagnosis (stage IV) or later as recurrent disease (stage II-III). Loss of 1p36.11-21 was associated with tumour dissemination in microsatellite stable tumours of stage II-IV (odds ratio = 5.5). It was enriched to a similar extent in tumours with distant recurrence within stage II and stage III subgroups, and may therefore be used as a prognostic marker at diagnosis. Loss of 1p36.11-21 relative to average copy number of the genome showed similar prognostic value compared to absolute loss of copies. Therefore, the use of relative loss as a prognostic marker would benefit more patients by applying also to hyperploid cancer genomes. The association with tumour dissemination was supported by independent data from the The Cancer Genome Atlas. Deletions on 1p36 may be used to guide adjuvant treatment decisions in microsatellite stable colon cancer of stages II and III.

  15. A Bayesian predictive two-stage design for phase II clinical trials.

    Science.gov (United States)

    Sambucini, Valeria

    2008-04-15

    In this paper, we propose a Bayesian two-stage design for phase II clinical trials, which represents a predictive version of the single threshold design (STD) recently introduced by Tan and Machin. The STD two-stage sample sizes are determined specifying a minimum threshold for the posterior probability that the true response rate exceeds a pre-specified target value and assuming that the observed response rate is slightly higher than the target. Unlike the STD, we do not refer to a fixed experimental outcome, but take into account the uncertainty about future data. In both stages, the design aims to control the probability of getting a large posterior probability that the true response rate exceeds the target value. Such a probability is expressed in terms of prior predictive distributions of the data. The performance of the design is based on the distinction between analysis and design priors, recently introduced in the literature. The properties of the method are studied when all the design parameters vary.

  16. Statistical inference for extended or shortened phase II studies based on Simon's two-stage designs.

    2015-06-07

    Simon's two-stage designs are popular choices for conducting phase II clinical trials, especially in the oncology trials to reduce the number of patients placed on ineffective experimental therapies. Recently Koyama and Chen (2008) discussed how to conduct proper inference for such studies because they found that inference procedures used with Simon's designs almost always ignore the actual sampling plan used. In particular, they proposed an inference method for studies when the actual second stage sample sizes differ from planned ones. We consider an alternative inference method based on likelihood ratio. In particular, we order permissible sample paths under Simon's two-stage designs using their corresponding conditional likelihood. In this way, we can calculate p-values using the common definition: the probability of obtaining a test statistic value at least as extreme as that observed under the null hypothesis. In addition to providing inference for a couple of scenarios where Koyama and Chen's method can be difficult to apply, the resulting estimate based on our method appears to have certain advantage in terms of inference properties in many numerical simulations. It generally led to smaller biases and narrower confidence intervals while maintaining similar coverages. We also illustrated the two methods in a real data setting. Inference procedures used with Simon's designs almost always ignore the actual sampling plan. Reported P-values, point estimates and confidence intervals for the response rate are not usually adjusted for the design's adaptiveness. Proper statistical inference procedures should be used.

    Full Text Available Vulvar cancer is a gynecological cancer whose incidence rate is relatively low. Patients generally were admitted at advanced stage, and radiation therapy at advanced stage does not provide favorable prognosis. Two main modalities in the treatment of vulvar cancer are surgery and radiation therapy. However, radiation can be performed in early stage vulvar cancer but surgery is thought to have more benefits, such as in side effect on the ovary/ reproductive function disorder, patient's hygiene factor, and the ease in performing therapy if recurrence occurs. There are various techniques of vulvar cancer surgery, such as radical vulvectomy with butterfly incision (RVBI and radical vulvectomy with separated incision (RVSI. The objective of this study was to identify the benefits of radical vulvectomy with separated incision in comparison with radical vulvectomy with butterfly incision in terms of the length of surgery, wound recovery, infection incidence, length of hospital stay. This study was a clinical trial performed during the period of 1990-2000. Fifteen cases of vulvar cancer were found and underwent surgery. Fourteen cases were at stage II and 14 cases were histologically defined as squamous-cell carcinoma and 1 case was adenocarcinoma. The average length of surgery in RVSI was 168 minutes, this was shorter than that in VRBI which reached an average of 275 minutes. The incidence of infection in RVSI group was 3 of 11 cases (27.27%, while in RVBI group all cases had infection in surgical wound. Failure of surgical wound approximation was 1 of 12 cases (9.99%, while in RVBI all cases experienced the failure such that cosmetic surgery was required. Length of postoperative care in RVSI group was 12.3 days, while in RVBI 21.5 days. Thus, complications in VRBI were lower, and length of surgery and length of postoperative care were shorter.

    Objective: MRI findings of cerebral paragonimiasis in early stage is important to improve the diagnosis and therapy of this disease. Accordingly, this study was undertaken to evaluate the MRI features of early cerebral paragonimiasis. Methods: MRI features in 4 cases between 6 and 13 years old with cerebral paragonimiasis in the early stage were retrospectively reviewed. The diagnosis was based on a positive antibody test by enzyme-linked immunosorbent assay (ELISA) for paragonimiasis in serum and effective therapy. Conventional MRI was performed by using spin echo (SE) pulse sequences in 4 cases and MRA was performed in one case. Results: The common findings were multiple irregular hemorrhage, part of them surrounded with edema signals which often showed large unsuitable edematous area centered with small hemorrhagic lesion. Lesions of two cases were just localized in cerebral lobes and the other two cases could be found in cerebrum, cerebellum and brain stem which showed the lesions distributed in random ways, Most lesions showed the shapes of assembling and migrating. The characteristic appearance was 'tunnel sign' which showed the migrating track of adult worm. 'Tunnel sign' on T 1 WI showed tunnel-like high signal in early stage and low signal in later stage. Conclusion: MRI findings of multiple irregular hemorrhage, unsuitable surrounding edema, assembling and migrating lesions and 'tunnel sign' are suggestive of early active cerebral paragonimiasis

    According to the Procedural Deficit Hypothesis (PDH), difficulties in the procedural memory system may contribute to the language difficulties encountered by children with Specific Language Impairment (SLI). Most studies investigating the PDH have used the sequence learning paradigm; however these studies have principally focused on initial sequence learning in a single practice session. The present study sought to extend these investigations by assessing the consolidation stage and longer-term retention of implicit sequence-specific knowledge in 42 children with or without SLI. Both groups of children completed a serial reaction time task and were tested 24h and one week after practice. Results showed that children with SLI succeeded as well as children with typical development (TD) in the early acquisition stage of the sequence learning task. However, as training blocks progressed, only TD children improved their sequence knowledge while children with SLI did not appear to evolve any more. Moreover, children with SLI showed a lack of the consolidation gains in sequence knowledge displayed by the TD children. Overall, these results were in line with the predictions of the PDH and suggest that later learning stages in procedural memory are impaired in SLI. Copyright © 2015 Elsevier Ltd.

    PURPOSE: To determine whether patients with early-stage SBBC can be safely and effectively treated with bilateral BCT. MATERIALS and METHODS: We retrospectively reviewed records of 26 patients with clinical Stage I-II SBBC treated between 1968-1989 with bilateral BCT. SBBC was defined as tumors diagnosed no more than one month apart, with both sides demonstrating invasive cancer. Maximum (max) clinical stage was based on the more advanced breast tumor. Median age at diagnosis was 56 years (range, 32-85 years); menopausal status was 6 pre-, 16 post-, 3 peri-, and 1 unknown at diagnosis. Median follow-up for surviving pts is 95 months (range, 68-157). Outcome was compared to 1325 pts with unilateral Stage I or II breast cancer, within the same age range, treated during the same time period. There were no significant differences in median age, median total dose, tumor size, estrogen receptor (ER) status, pathologic nodal status, and use of systemic therapy between the study population and the comparison group. Local recurrence (LR) was evaluated as true recurrence (TR, i.e., in the original tumor bed), marginal miss (MM, at the edge of the boost field), or elsewhere (E). Median total dose to the primary was 6100 cGy (range, 5000-7000). Pathology was available for review in 19 cases. Cytology (nuclear and cytoplasmic features) was similar in (7(19)) evaluable cases, and architecture (growth pattern, ie, papillary, solid) was similar in (5(19)) cases. The presence of either cytologic or architectural similarity was noted in(9(19)) cases. 7 of 19 pts who had axillary lymph node evaluation on at least one side had pathological confirmation of lymph node metastasis. Stage was the same in both breasts in 13 cases (10 Stage I, 3 Stage II); ER status data was complete in 11 pts, and the same in both primaries in 9 cases. Cosmetic results and complications after BCT were scored. Statistical significance was evaluated by use of the Fisher exact test. RESULTS: The 5-yr actuarial

    The records of 690 Stage I and II breast cancer patients (31% of them with transfusions), who underwent mastectomy with axillary dissection were examined whether perioperative blood transfusion might be detrimental to survival. The overall 5- and 1-year survival rates for 477 patients who had not received transfusions were 75% and 63% respectively, compared with 66% and 49% for those who had transfusions (p=0.005). There was no significant difference between the group in any other of the most important prognostic factors. An analysis of the subpopulation of patients with favorable prognostic factors yielded similar results. A multivariate analysis indicated that blood transfusion was one of the four variables significantly related to survival. (author)

    Progress in the management of non-Hodgkin's lymphomata has been impeded by lack of information on the natural history of these diseases. Confusion about the significance of histopathology, extranodal presentations and routes of spread renders much of previously published data relatively uninterpretable. To evaluate the relative prognostic significance of presentation, histopathology and lymphography, a retrospective study was undertaken on 226 patients with Stage I and II disease, who were treated with intensive irradiation to the involve regions. The slides on these patients were reviewed and reclassified in terms of the Rappaport system. The results of this study demonstrated that a nodular histopathological pattern was the most important prognostic factor. The significance of this finding and other factors are discussed in terms of possible new approaches to treatment.

    To (1) evaluate rates of surgery for clinical stage I-II pancreatic ductal adenocarcinoma (PDAC), (2) identify predictors of not undergoing surgery, (3) quantify the degree to which patient- and hospital-level factors explain differences in hospital surgery rates, and (4) evaluate the association between adjusted hospital-specific surgery rates and overall survival (OS) of patients treated at different hospitals. Curative-intent surgery for potentially resectable PDAC is underutilized in the United States. Retrospective cohort study of patients ≤85 years with clinical stage I-II PDAC in the 2004 to 2014 National Cancer Database. Mixed effects multivariable models were used to characterize hospital-level variation across quintiles of hospital surgery rates. Multivariable Cox proportional hazards models were used to estimate the effect of adjusted hospital surgery rates on OS. Of 58,553 patients without contraindications or refusal of surgery, 63.8% underwent surgery, and the rate decreased from 2299/3528 (65.2%) in 2004 to 4412/7092 (62.2%) in 2014 (P < 0.001). Adjusted hospital rates of surgery varied 6-fold (11.4%-70.9%). Patients treated at hospitals with higher rates of surgery had better unadjusted OS (median OS 10.2, 13.3, 14.2, 16.5, and 18.4 months in quintiles 1-5, respectively, P < 0.001, log-rank). Treatment at hospitals in lower surgery rate quintiles 1-3 was independently associated with mortality [Hazard ratio (HR) 1.10 (1.01, 1.21), HR 1.08 (1.02, 1.15), and HR 1.09 (1.04, 1.14) for quintiles 1-3, respectively, compared with quintile 5] after adjusting for patient factors, hospital type, and hospital volume. Quality improvement efforts are needed to help hospitals with low rates of surgery ensure that their patients have access to appropriate surgery.

    To study and summarize the etiology of children patients with chronic kidney disease (CKD) stage 2 to 5 seen in Children's Hospital of Fudan University from Jan. 2004 to Dec. 2013. By complying with the NKF-K/DOQI guidelines, we collected data of 264 cases of children patients with CKD stage 2-5 from Jan. 2004 to Dec. 2013 in the medical record system of Children's Hospital of Fudan University. And we retrospectively analyzed their age and CKD stage at first diagnosis, primary diseases, complications, etc. In the collected 264 cases, 52 cases (19.7%) were diagnosed at stage 2, 67 (25.4%) at stage 3, 52 (19.7%) at stage 4 and 93 (35.2%) at stage 5. For disease causes, 116 cases (43.9%) had congenital anomalies of the kidney and urinary tract (CAKUT), 61 cases (23.1%) had glomerular disease, 15 (5.7%) had hereditary kidney disease, 14 (5.3%) had other diseases and in 58 cases (22.0%) the causes of disease were unknown. In the group with age between 0 and 3.0 and 3.1 and 6.0 years, 57.1% (24 cases) and 60.0% (30 cases) had primary disease with CAKUT. In the group with age older than 10 years, 49.2% (30 cases) had primary disease with glomerular disease and 32.0% (32 cases) with unknown causes. The major cause of CKD stage 2-5 in children in our hospital during the last ten years was CAKUT (43.9%), followed by glomerular disease (23.1%). The primary diseases of CKD were significantly different between the 2 age groups. CAKUT was more common in infants and preschool children while for adolescents, glomerular disease was the major cause.

    Elevated intact parathyroid hormone (iPTH) levels can contribute to morbidity and mortality in children with chronic kidney disease (CKD). We evaluated the pharmacokinetics, efficacy, and safety of oral paricalcitol in reducing iPTH levels in children with stages 3-5 CKD. Children aged 10-16 years with stages 3-5 CKD were enrolled in two phase 3 studies. The stage 3/4 CKD study characterized paricalcitol pharmacokinetics and compared the efficacy and safety of paricalcitol with placebo followed by an open-label period. The stage 5 CKD study evaluated the efficacy and safety of paricalcitol (no comparator) in children with stage 5 CKD undergoing dialysis. In the stage 3/4 CKD study, mean peak plasma concentration and area under the time curve from zero to infinity were 0.13 ng/mL and 2.87 ng•h/((or ng×h/))mL, respectively, for 12 children who received 3 μg paricalcitol. Thirty-six children were randomized to paricalcitol or placebo; 27.8% of the paricalcitol group achieved two consecutive iPTH reductions of ≥30% from baseline versus none of the placebo group (P = 0.045). Adverse events were higher in children who received placebo than in those administered paricalcitol during the double-blind treatment (88.9 vs. 38.9%; P = 0.005). In the stage 5 CKD study, eight children (61.5%) had two consecutive iPTH reductions of ≥30% from baseline, and five (38.5%) had two consecutive iPTH values of between 150 and 300 pg/mL. Clinically meaningful hypercalcemia occurred in 21% of children. Oral paricalcitol in children aged 10-16 years with stages 3-5 CKD reduced iPTH levels and the treatment was well tolerated. Results support an initiating dose of 1 μg paricalcitol 3 times weekly in children aged 10-16 years.

    This is a retrospective analysis of 233 evaluable patients with stage I-II squamous cell carcinoma of the oral cavity treated by definitive brachytherapy. Minimum follow-up is 3 years. Treatment of the neck was chosen by a multidisciplinary team, according to age, medical status and availability for follow-up. One hundred and ten patients (47 percent) underwent elective neck dissection (END), 28 (25 percent) had positive nodes and received neck irradiation post-operatively. One hundred and twenty-three patients (53 percent) were regularly followed up only, with therapeutic neck dissection (TND) reserved for cases of node relapses. In the END group, there were 19 neck relapses (17 percent): 12/60 (20 percent) in patients with mobile tongue carcinoma and 7/50 (14 percent) in patients with floor of the mouth carcinoma. Salvage treatment was successful in 13-21 (62 percent) cases. Ten-year survival is 37 percent for the END-group and 31 percent for the TND group. Tumour stage and infiltration into underlying tissues increased the probability of neck relapse and death. Furthermore, a multivariate analysis showed that patients treated in the TND group had a higher probability of death than patients treated in the END group (p<0.04).

    Purpose: To assess the role of radiation therapy in the treatment of primary localized (Stage I: 24 cases and Stage II: 13 cases) non-Hodgkin's Lymphoma (NHL) of the oral cavity. Methods and Materials: In total, 37 patients (27 male, 10 female) with primary localized NHL of the oral cavity have been treated with radiotherapy alone (23 cases) or radiation with chemotherapy (14 cases). The age range was 29 to 86 years (median: 65). Clinical and treatment variables with potential prognostic significance for survival were evaluated by univariate and multivariate analysis. Of the 37 patients, 31 (84%) had intermediate-grade lymphomas and six (14%) had high-grade lymphomas. Four patients showed necrotic ulcer in the central portion of the hard palate. Results: The 5-year actuarial survival rate for all cases was 73%. The 5-year survival rates for intermediate-grade and high-grade lymphoma were 85% and 14%, respectively. Significant prognostic factors identified by the multivariate analysis were histologic grade of malignancy (p = 0.02) and central necrotic ulcer in the tumor (p = 0.02). Chemotherapy did not improve survival (p = 0.41). Conclusions: Our analysis suggests that radiotherapy alone may be approved as the treatment for localized oral NHL with no ulceration and intermediate histology. However, patients with high-grade lymphoma and/or necrotic ulcer are difficult to cure with radiation alone and aggressive treatment should be advocated to improve survival

    Peripheral arterial obstructive disease (PAOD) of the lower limbs affects 5% of the adult population. Uncontrolled arteriopathy is established due to a microcirculatory deficit, which may be present despite a good Winsor index and which leads to exhaustion of the functional microcirculatory reserve. The target of this study was to examine possible improvements in microvascular and tissue homeostasis by the administration of propionyl-L-carnitine (PLC). A total of 26 patients were enrolled in this study, aged 65 +/- 15 years; two males were diagnosed at stage IIA and 17 males and seven females at stage IIB PAOD. The main criterion of inclusion was the worsening of walking distance during the last month. In this study the duration of therapy was 33 days. PLC was administered in three flasks, each containing 300 mg in 250 cc saline by continuous infusion. The following parameters were measured before and after treatment: pain-free and maximum walking distance (measured on a treadmill at 3.2 km/hr with a gradient of 12%), recovery time from pain after maximum walking distance, ankle-brachial index by means of the Doppler apparatus, and evaluation of the microcirculation using capillaroscopy. The results showed that therapy with PLC was effective at restoring activity of skeletal muscle in ischemic conditions. In particular, capillaroscopy showed improvement in the angioarchitecture in the microcirculation fields, expressed as increased numbers of visible capillaries and diminution in the time of loss of sodium fluorescein marker. The clinical data showed increased walking distance and diminished time to recover from pain, and the clinical improvement correlated with improved microcirculatory function. From these preliminary data has emerged an indication of therapy with PLC for chronic obstructive arteriopathy of the lower limbs at stage II. Further studies with higher numbers of patients and more controlled variables are planned.

    Phase II clinical trials in oncology are performed to evaluate the therapeutic efficacy of a new treatment regimen. A common measure of efficacy for these trials is the proportion of patients who obtain a response measured by tumor shrinkage. It is standard practice to classify this response into the following categories: (1) complete response (CR); (2) partial response (PR); (3) stable disease; and (4) progression of disease. Tumor response is then treated as a binary variable whereby patients who achieve either a CR or a PR are considered responders and all others nonresponders. A two-stage design that allows for early termination of the trial if the treatment shows little efficacy such as Gehan or Simon gives equal weight to a CR and a PR. However, a CR, defined as complete disappearance of the tumor, is more likely than a PR to signal an important antitumor effect and result in a survival advantage. We argue that CRs and PRs should be considered separately, and hence we propose a two-stage design with a multilevel endpoint (i.e., CR, PR, and nonresponders). This design is an extension of Simon's optimal two-stage design and is based on a trinomial model. For most scenarios the proposed design results in an improvement in expected sample size compared to Simon's optimal design. Design optimization was performed by a direct search based on enumerating exact trinomial probabilities. Sample size tables are provided for parameter sets commonly used in the oncologic setting.

    Full Text Available Objective: To assess the prognostic value of DNA‐image cytometry in cervical carcinoma of the uterus and its relation to other established prognostic factors. Study design: The study included 116 cases of cervical carcinoma FIGO stages IB and II which were treated with radical abdominal hysterectomy. The median follow‐up was 55 months (range 1–162 months. DNA image cytometry was performed on cytologic specimens prepared by enzymatic cell separation from formalin‐fixed, paraffin‐embedded tissues. DNA stemline ploidy, DNA stemline aneuploidy, 5c exceeding rate, 9c exceeding rate, 2c deviation index, and DNA malignancy grade were computed. DNA‐variables as well as various clinical and histological variables were related to survival rates. Results: In multivariate statistical analysis DNA stemline ploidy using 2.2c as a cut‐off value and FIGO stage showed to be statistically significant available presurgery predictors of survival, whereas the postsurgical parameters lymphonodal status, tumor size and parametrial involvement were significantly correlated with survival. The synopsis of all parameters in a multivariate Cox model indicated that – with declining relevance – the number of positive pelvic lymph nodes, DNA stemline ploidy using a cut‐off level at a modal value of 2.2c, largest pelvic lymph node, 5c exceeding rate, and ratio of carcinoma area to cervix area, were of predictive value for survival. Conclusions: Our results suggest that prognostic information deducted from classical staging parameters is successfully complemented by DNA image cytometry which can be applied pretherapeutically.

    Purpose/Objectives(s): Early-stage endometrial cancer patients are at higher risk of noncancer mortality than of cancer mortality. Competing event models incorporating comorbidity could help identify women most likely to benefit from treatment intensification. Methods and Materials: 67,397 women with stage I-II endometrioid adenocarcinoma after total hysterectomy diagnosed from 1988 to 2009 were identified in Surveillance, Epidemiology, and End Results (SEER) and linked SEER-Medicare databases. Using demographic and clinical information, including comorbidity, we sought to develop and validate a risk score to predict the incidence of competing mortality. Results: In the validation cohort, increasing competing mortality risk score was associated with increased risk of noncancer mortality (subdistribution hazard ratio [SDHR], 1.92; 95% confidence interval [CI], 1.60-2.30) and decreased risk of endometrial cancer mortality (SDHR, 0.61; 95% CI, 0.55-0.78). Controlling for other variables, Charlson Comorbidity Index (CCI) = 1 (SDHR, 1.62; 95% CI, 1.45-1.82) and CCI >1 (SDHR, 3.31; 95% CI, 2.74-4.01) were associated with increased risk of noncancer mortality. The 10-year cumulative incidences of competing mortality within low-, medium-, and high-risk strata were 27.3% (95% CI, 25.2%-29.4%), 34.6% (95% CI, 32.5%-36.7%), and 50.3% (95% CI, 48.2%-52.6%), respectively. With increasing competing mortality risk score, we observed a significant decline in omega (ω), indicating a diminishing likelihood of benefit from treatment intensification. Conclusion: Comorbidity and other factors influence the risk of competing mortality among patients with early-stage endometrial cancer. Competing event models could improve our ability to identify patients likely to benefit from treatment intensification.

    The DNA cleavage produced by 4'-(9-acridinylamino)methanesulfon-m-anisidide (m-AMSA) in mammalian cells is putatively mediated by topoisomerase II. The authors found that in synchronized HeLa cells the frequency of such cleavage was 4-15-fold greater in mitosis than in S while the DNA of G 1 and G 2 cells exhibited an intermediate susceptibility to cleavage. The hypersensitivity of mitotic DNA to m-AMSA-induced cleavage was acquired relatively abruptly in late G 2 and was lost similarly abruptly in early G 1 . The susceptibility of mitotic cells to m-AMSA-induced DNA cleavage was not clearly paralleled by an increase in topoisomerase II activity in 350 mM NaCl extracts from mitotic cells compared to similar extracts from cells in G 1 , S, or G 2 . Furthermore, equal amounts of decatenating activity from cells in mitosis and S produced equal amounts of m-AMSA-induced cleavage of simian virus 40 (SV40) DNA; i.e., the interaction between m-AMSA and extractable enzyme was similar in mitosis and S. The DNA of mitotic cells was also hypersensitive to cleavage by 4'-demethylepipodophyllotoxin 4-(4,6-O-ethylidene-β-D-glucopyranoside) (etoposide), a drug that produces topoisomerase II mediated DNA cleavage without binding to DNA. Cell cycle stage dependent fluctuations in m-AMSA-induced DNA cleavage may result from fluctuations in the structure of chromatin per se that occur during the cell cycle. Surprisingly, cell cycle stage dependent differences in m-AMSA-induced DNA cleavage did not correlate with differences in the susceptibility to the cytotoxic effects of the drug. In fact, cells in S were most sensitive to these effects. These results are an exception to the previously observed parallel between the susceptibility of mammalian cells to drug-induced DNA cleavage and the susceptibility of the cells to drug-induced cytotoxicity and indicate the complexity of any relationship between the two phenomena

    Quality of life in addition to various medical problems in children with end-stage renal disease (ESRD) should be objectively assessed to accomplish normal growth and development during childhood. However, unfortunately, studies of quality of life (QoL) in children with ESRD have been not popular yet and there are only fewer suitable assessment tools compared with adults. Recently, disease-specific modules to evaluate QoL in children with chronic disease such as ESRD have been developed. This review was made to introduce these QoL instruments for children and help the clinical application of them.

    Treatment results of 244 patients with stage I-II cancer of the mobile tongue were analyzed according to the modalities employed (implantation, surgery, cryosurgery and intraoral irradiation). Overall local control rates at 3 years were 90+-3 percent for implant, 89+-7 percent for cryosurgery, and 84+-9 percent for surgery. Local control rates in stage II patients treated with intraoral electron irradiation, however, were only 50+-13 percent. Five-year survival rates were 72+-3 percent with no significant differences observed in patients with either stage I or stage II regardless of treatment modality. Sixty percent (29/48) of the patients with local recurrences were salvaged by the 2nd treatment. Since the local control and survival achieved by these modalities were similar, with the exception of patients with stage II treated by intraoral electron irradiation, authors recommend inter-stitial implantation with iridium, intraoral electron irradiation or surgery for patients with T 1 tumors, and iridium implantation or surgery for patients with T 2 tumors. For those with superficial lesions measuring 5 mm or less in thickness, cryosurgery is being offered as an alternative. The patient can choose the treatment modality taking into account his/her age, sex and profession. (author). 13 refs.; 1 fig.; 4 tabs

    Full Text Available The purpose of the present study was to establish a non-surgical breast-conserving treatment (BCT using KORTUC II radiosensitization treatment. A new radiosensitizing agent containing 0.5% hydrogen peroxide and 0.83% sodium hyaluronate (a CD44 ligand has been developed for intra-tumoral injection into various tumors. This new method, named KORTUC II, was approved by our local ethics committee for the treatment of breast cancer and metastatic lymph nodes. A total of 72 early-stage breast cancer patients (stage 0, 1 patient; stage I, 23; stage II, 48 were enrolled in the KORTUC II trial after providing fully informed consent. The mean age of the patients was 59.7 years. A maximum of 6 mL (usually 3 mL for tumors of less than approximately 3 cm in diameter of the agent was injected into breast tumor tissue twice a week under ultrasonographic guidance. For radiotherapy, hypofraction radiotherapy was administered using a tangential fields approach including an ipsilateral axillary region and field-in-field method; the energy level was 4 MV, and the total radiation dose was 44 Gy administered as 2.75 Gy/fraction. An electron boost of 3 Gy was added three times. Treatment was well tolerated with minimal adverse effects in all 72 patients. No patients showed any significant complications other than mild dermatitis. A total of 24 patients under 75 years old with stage II breast cancer underwent induction chemotherapy (EC and/or taxane prior to KORTUC II treatment, and 58 patients with estrogen receptor-positive tumors also received hormonal therapy following KORTUC II. The mean duration of follow-up as of the end of September 2014 was 51.1 months, at which time 68 patients were alive without any distant metastases. Only one patient had local recurrence and died of cardiac failure at 6.5 years. Another one patient had bone metastases. For two of the 72 patients, follow-up ended after several months following KORTUC II treatment. In conclusion, non

    To analyze the clinicopathologic factors related to recurrence and metastasis of stage II or III colon cancer after radical resection. The clinical and pathological data of 628 patients with stage II or III colon cancer after radical resection from Jan. 2005 to Dec. 2008 in our hospital were retrospectively reviewed and analyzed. The overall recurrence and metastasis rate was 28.5% (179/628). The 5-year disease-free survival (DFS) rate was 70.3% and 5-year overall survival (OS) rate was 78.5%. Univariate analysis showed that age, smoking intensity, depth of tumor invasion, lymph node metastasis, TNM stage, gross classification, histological differentiation, blood vessel tumor embolus, tumor gross pathology, multiple primary tumors, preoperative and postoperative serum concentration of CEA and CA19-9, and the regimen of adjuvant chemotherapy were correlated to recurrence and metastasis of colon cancer after radical resection. Multivariate analysis showed that regional lymph node metastasis, TNM stage, the regimen of postoperative adjuvant chemotherapy, and preoperative serum concentration of CEA and CA19-9 were independent factors affecting the prognosis of colon cancer patients. Regional lymph node metastasis, TNM stage, elevated preoperative serum concentration of CEA and CA19-9, the regimen of postoperative adjuvant chemotherapy with single fluorouracil type drug are independent risk factors of recurrence and metastasis in patients with stage II-III colon cancer after radical resection.

    Adjuvant chemotherapy has been known as a standard treatment for patients with resected colon cancer. However, in elderly colon cancer patients, the characteristics of patients are heterogeneous with regard to life expectancy and comorbidities. Thus, with regard to the effectiveness of adjuvant chemotherapy for colon cancer, it is difficult to extrapolate data of clinical trials from the younger into the older general population. Data for 382 elderly colon cancer patients were analyzed: 217 in Stage II and 165 in Stage III. The efficacy of adjuvant chemotherapy was evaluated in elderly colon cancer patients after a match by the propensity score method. For matched patients with Stage II colon cancer, there was no significant efficacy of adjuvant chemotherapy in the risk of death during all follow-up periods (P-value, 0.06-0.37). Though there was a tendency that the adjuvant chemotherapy reduces the death rate during the follow-up periods, it was not statistically significant. In the case of Stage III, the adjuvant chemotherapy was significantly effective in matched patients for 5-year (hazard ratio [HR], 0.69; 95% confidence interval [CI], 0.30-0.90) and overall survival (HR, 0.56; 95% CI, 0.34-0.94). Adjuvant chemotherapy for elderly patients with Stage II colon cancer is not effective, whereas elderly patients with Stage III with adjuvant chemotherapy appear to have a better survival rate in the general population.

    Introduction: micro satellite instability (MSI) is a good prognostic factor in colorectal cancer (CRC) located. Its value as a predictive marker against adjuvant treatment of chemotherapy (CT) has been shown fluoropyrimidine in various publications. The MSI occurs in 15% of colorectal tumors and sporadic in 90% of tumors in the context of colorectal cancer syndrome hereditary nonpolyposis. In Uruguay there are no studies about this phenomenon. Objective: To determine the incidence of micro satellite instability in a sample of patients using the Hospital Central de las fuerzas armadas oncology service, association with a compatible family history and the histological features of the tumors associated therewith. Methods: The medical records of patients were analyzed with CRC diagnosed stage II between 01/2001 and 12/2009. Data of the patients were analyzed which had complete histology and evolution. Results: 30/52 patients (57.6%) were analyzed. 40% had a detected MSI by kits for Pcr (polymerase chain reaction) to D2S123, D5S250, D17S346, BAT25 and BAT26 according to the Bethesda criteria. In those patients they filed a MSI: the median age was 70 years; 58.3% male. No patient had a family history consistent with HNPCC. 5.6% (3) they received Adjuvant chemotherapy treatment. Regarding tumor characteristics: 75% (9) were T3, and T4 were 25% (3); 8.3% histologic grade I (1) II 58.3% (7) 8.3% III (1) without Data 33% (6). This tumor lymphocyte infiltration was reported in 25% (3), absent 33.3% (4), not reported in 41.6% (5). Conclusions: This is the first analysis of these characteristics carried out in Uruguay. The same has been detected MSI percentage higher than reported in the literature International. In either case a compatible family history met HNPCC

    Purpose: To identify a cohort of women treated with neoadjuvant chemotherapy and mastectomy for whom postmastectomy radiation therapy (PMRT) may be omitted according to the projected risk of local-regional failure (LRF). Methods and Materials: Seven breast cancer physicians from University of California cancer centers created 14 hypothetical clinical case scenarios, identified, reviewed, and abstracted the available literature (MEDLINE and Cochrane databases), and formulated evidence tables with endpoints of LRF, disease-free survival, and overall survival. Using the American College of Radiology appropriateness criteria methodology, appropriateness ratings for postmastectomy radiation were assigned for each scenario. Finally, an overall summary risk assessment table was developed. Results: Of 24 sources identified, 23 were retrospective studies from single institutions. Consensus on the appropriateness rating, defined as 80% agreement in a category, was achieved for 86% of the cases. Distinct LRF risk categories emerged. Clinical stage II (T1-2N0-1) patients, aged >40 years, estrogen receptor-positive subtype, with pathologic complete response or 0-3 positive nodes without lymphovascular invasion or extracapsular extension, were identified as having ≤10% risk of LRF without radiation. Limited data support stage IIIA patients with pathologic complete response as being low risk. Conclusions: In the absence of randomized trial results, existing data can be used to guide the use of PMRT in the neoadjuvant chemotherapy setting. Using available studies to inform appropriateness ratings for clinical scenarios, we found a high concordance of treatment recommendations for PMRT and were able to identify a cohort of women with a low risk of LRF without radiation. These low-risk patients will form the basis for future planned studies within University of California Athena Breast Health Network.

    The aim of this study was to describe the impact of postoperative adjuvant treatment modalities and identify risk factors associated with recurrence and survival rates in women diagnosed with early stage type II endometrial cancer and carcinosarcoma. In this retrospective study, patients diagnosed with early stage (stages I-II) carcinosarcoma and type II endometrial cancer were reviewed. All women underwent comprehensive surgical staging. Postoperative treatment options of chemotherapy (CT), radiotherapy (RT), observation (OBS) and chemotherapy-radiotherapy (CT-RT) combination were compared in terms of recurrence and survival outcome. In CT-RT treatment arm, recurrence rate was found as 12.5% and this result is significantly lower than the other treatment approaches (P = 0.01 CT alone: 33.3%, RT alone: 26.7%, OBS: 62.5%). Three-year disease free survival(DFS) rate and overall survival (OS) rate were statistically higher for the group of women treated with combination of CT-RT (92-95%) compared to the women treated with RT alone (65-72%), treated with CT alone (67-74%) and women who received no adjuvant therapy (38-45%). The multivariate analysis revealed that carcinosarcoma histology was associated with shortened DFS and OS (P = 0.001, P = 0.002). On the other hand, being at stage Ia (P = 0.01, P = 0.04) and receiving adjuvant treatment of CT-RT combination (P = 0.005, P = 0.002) appeared to lead to increased DFS and OS rates. We identified that a combination treatment of chemotherapy and radiotherapy is superior compared to other postoperative adjuvant treatment approaches concerning PFS, OS and recurrence rates in stages I-II of type II endometrial cancers and uterine carcinosarcoma. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Thymoma has malignant potential and is the most common anterior mediastinal tumor. Video-assisted thoracic surgery (VATS), which is less invasive surgical procedure, is a good option for resecting Masaoka stage I tumors. Whether VATS is appropriate, depends on the surgeon's judgment and accurate imaging diagnosis. We introduce a technique involving a combination of video-assisted thoracoscopic thymectomy (VAT-T) and lateral thoracotomy for stage II and some stage III thymomas that have locally invaded the lung and/or pericardium.

    Full Text Available Abstract Background There is no consensus as to the prognostic model for brachytherapy of tongue carcinoma. This study was designed to evaluate the prognostic factors for local control based on a large population under a unified treatment policy. Results Between 1970 and 1998, 433 patients with stage II tongue squamous cell carcinoma were treated by low-dose-rate brachytherapy. This series included 277 patients treated with a linear source with a minimum follow-up of 3 years. A spacer was introduced in 1987. The primary local control rates were 85.6%. Conclusion In the multivariate analysis, an invasive growth pattern was a significant factor for local recurrence. The disease-related survival was influenced by old age and an invasive growth pattern. A spacer lowered mandibular bone complications. The growth pattern was the most important factor for recurrence. Brachytherapy was associated with a high cure rate and the use of spacers brought about good quality of life (QOL.

    Women at risk for delayed onset of lactation are often advised to pump their breasts before lactogenesis stage II to hasten the timing of this process. The effectiveness of this clinical practice has not been previously evaluated. This study investigates the effects of breast pumping before the onset of lactation on early milk transfer and subsequent breastfeeding duration among women giving birth by cesarean delivery. Sixty women were randomly assigned to either the pumping group (n = 30), which used a double electric breast pump for six 10- to 15-minute sessions from 24 to 72 hours postpartum, or to the control group (n = 30), which held the pump to their breasts without suction for the same amount of time. Milk transfer was assessed by test weighing infants before and after 3 breastfeeding sessions daily. Test weight data were fitted to a second-order polynomial curve, to predict milk transfer over time. Breast pumping between 24 and 72 hours after cesarean delivery did not improve milk transfer. Participants in the pumping group tended to have lower milk transfer than did controls. Primiparae in the pumping group breastfed for ~5 months less than their counterparts in the control group; however, this difference was not statistically significant. Breast pumping did not improve milk transfer during the first 72 hours postpartum and may negatively affect breastfeeding duration among primiparous women. lactation, lactogenesis, breast milk, breast pumping, milk expression, breastfeeding, cesarean delivery.

    Purpose: At least in some European Countries, there is still considerable controversy regarding the choice between surgery and radiotherapy for the treatment of patients with early laryngeal-glottic carcinoma. Methods and Materials: Two hundred and forty-six patients with laryngeal-glottic neoplasms, Stage I-II, were treated with radical radiotherapy. Before radiotherapy the patients were evaluated to determine the surgical procedure of choice. Either 66-68.4 Gy (33-38 fractions) or 63-65 Gy (28-29 fractions) of radiation therapy (RT) were administered. The overall disease free survival was determined for each subgroup of patients. Univariate and multivariate analyses were performed to determine significant prognostic variables. Results: Five- and 10-year overall survival rates were 83 and 72%, respectively. At a median follow-up of 6 years 204 patients are alive and disease free. No patient developed distant metastases. One patient died of a large local recurrence, 38 patients died of causes unrelated to their tumor, and 3 patients were lost to follow-up. The multivariate analysis confirmed that performance status (PS), macroscopic presentation of the lesion, and persistence of dysphonia after radiotherapy are significant prognostic factors. Conclusions: According to the multivariate analysis, the patients with PS >80 and with exophytic lesions are eligible for radical RT. The surgical procedure proposed for each patient was not found to be an independent prognostic factor

    To evaluate the incidences of vaginal recurrence and toxicity after vaginal brachytherapy in Stage I-II endometrial cancer. Between 2003 and 2012, 150 high-intermediate-risk Stage I and 7 Stage II patients, median age 64 years, underwent surgery, with or without lymphadenectomy, and 3D brachytherapy: 7 Gy, at 5 mm depth from applicator surface, for 3-week fractions. The effects of age, grading, number of excised lymph nodes and pathologic stage on loco-regional relapse (LRR), metastases, and tumor-related death were investigated. Vaginal toxicity was evaluated during followup visits. At 83 months of median followup, 144 patients were disease free, 2 in relapse, 7 deceased from disease, and 4 from other causes. One vaginal (0.6%), five nodal (3.2%), three pelvic over the vaginal cuff (1.9%), and one distant recurrences were seen (0.6%). The 5-year probability of LRR-free, distant metastasis-free and cause-specific survivals for all patients were 93.6% (95% confidence interval [CI]: 88.1-96.7), 97.8% (95% CI: 93.2-99.3), and 96.5% (95% CI: 93.5-99.5) and for Stage I 95.7% (95% CI: 92.2-9.1), 99.3% (95% CI: 98.0-100), and 97.7% (95% CI: 95.2-100), respectively. At multivariate analysis, Stage II disease and more than 12 lymph nodes sampled were associated with LRR (hazard ratio [HR]: 3.88; 95% CI: 1.390-10.878; p = 0.010 and HR: 6.952; 95% CI: 1.591-30.385; p = 0.010) and Stage II with metastasis and tumor-related death (HR: 23.057; 95% CI: 2.296-231.485; p = 0.008 and HR: 4.324; 95% CI: 1.223-15.290; p = 0.023). Vaginal acute and chronic toxicity was 16% and 55.4%, respectively, all only Grades 1-2. For high-to-intermediate-risk Stage I endometrial cancer, 3D vaginal brachytherapy achieved good local control and low toxicity. In Stage II, patients brachytherapy could be administered after complete surgical staging. Copyright © 2016 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

    Objective: With the optimal therapy remains unclear for nasal NK/T cell lymphoma, the aim of this study is to analyze the outcome of radiotherapy as primary treatment for localized stage I E and II E diseases. Methods: Between January. 1983 and December 2003, 105 patients with stage I E and II E primary nasal NK/T cell lymphoma were retrospectively reviewed. According to the Ann Arbor Staging System, there were 83 stage I E and 22 stage II E. Stage I E was subdivided into limited stage I E confined to the nasal cavity (37 patients), or extensive stage I E with an extension beyond the nasal cavity (46 patients). Thirty-one patients received radiotherapy alone. Thirty-four patients were treated with radiotherapy followed by 2-4 cycles of chemotherapy. Thirty-seven patients were treated with chemotherapy followed by radiotherapy and 3 with chemotherapy alone. Of 83 patients with stage I E disease, 26 were primarily treated with radiotherapy alone, 30 with. radiotherapy followed by chemotherapy, and 27 with chemotherapy followed by radiotherapy. Results: The five-year overall survival (OS) and progression-free survival rates (PIS) for all patients was 71% and 59%, respectively. The 5-year OS for stage I E and stage II E was 78% and 46% (P<0.01), while the 5-year PFS for stage I E and stage II E was 63% and 40%, respectively (P<0.01). Patients with limited stage I E had a better OS and PFS than those with extensive stage I E, with 5-year OS and PFS of 82% and 80% versus 75% and 45%, respectively. Complete response (CR) was achieved in 91 (87%) patients after radiotherapy and/or chemotherapy. Initial radiotherapy resulted in a superior CR as compared to initial chemotherapy, with 54 of 65 (83%) patients achieving CR with initial radiotherapy, versus only 8 of 40 (20%) with initial chemotherapy. For 102 patients who received radiotherapy with or without chemotherapy, the outcome of primary, treatment with radiotherapy alone was compared to that of CMT. Five-year OS and

    The aim of this cross-sectional study was to evaluate the impact of dental caries on the quality of life of preschool children and their parents/caretakers, with an emphasis on the type of tooth and stage of progression. A randomly selected sample of preschool children, 3-5 yrs of age, underwent an oral examination for the assessment of dental caries using the International Caries Detection and Assessment System II (ICDAS II) criteria. Parents/caretakers answered two questionnaires, one on the oral health-related quality of life (OHRQoL) of the child [the Early Childhood Oral Health Impact Scale (ECOHIS)], and the other on the socio-economic characteristics of the family. Statistical analyses were performed using the chi-square test, Kruskal-Wallis test, Mann-Whitney U-test, and Poisson regression. A total of 451 preschool children participated in the study. The majority of carious lesions exhibited severe decay (60.6%) and were found in both anterior (incisors/canines) and posterior (molars) teeth. The final Poisson model revealed negative impacts on quality of life from more advanced stages of dental caries, both in incisors/canines and molars. Child's age and household income were also associated with impact on quality of life. Carious lesions in more advanced stages of progression in anterior and posterior teeth were associated with a negative impact on the quality of life of preschool children. © 2014 Eur J Oral Sci.

    A small number of lymph nodes retrieved (NLNR) is a known risk factor in stage II colorectal cancer. NLNR is influenced by age, but little is known about whether the impact of small NLNR on survival differs with age. This retrospective study sought to determine such impact in elderly patients with stage II colorectal cancer. We reviewed data for 2100 patients with stage II colorectal cancer who underwent surgery without adjuvant chemotherapy between January 1997 and December 2003. The optimal cutoff value of NLNR for survival was determined, and the impact of small NLNR on survival was analyzed. The association between age and NLNR was evaluated. The relation between age and risk of small NLNR with respect to survival was then assessed to determine the impact of small NLNR on elderly patients' survival. The optimal cutoff value of NLNR was determined as 6. The small NLNR group (SNG) showed significantly worse prognosis than the large NLNR group (LNG) (p patients (41.7 and 76.4 %, respectively; p patients (75.9 and 84.6 %, respectively; p = 0.083).

    Test weighing is the "gold standard" for documenting lactogenesis stage II. However, this method is impractical for use in population studies. Maternal perception of the timing of the onset of lactation may be a useful proxy for lactogenesis stage II. This study seeks to validate maternal perception of the onset of lactation as a marker of lactogenesis stage II. Women (n = 60) were recruited after cesarean delivery. Beginning at 24 h postpartum (pp), the onset of lactation was assessed 3 times daily by both test weighing and maternal perception. Delayed onset of lactation was defined as follows: 1) milk transfer /= 72 h pp. Misclassification analyses were conducted. Multivariate logistic regression, bivariate analyses and Cox survival analyses were used to evaluate the determinants and consequences of delayed onset of lactation, using both definitions. The sensitivity and specificity of delayed maternal perception as an indicator of delayed lactogenesis were 71.4 and 79.3%, respectively. Four risk factors for low milk transfer were significant (P: lactogenesis stage II.

    High-risk patients with stage II colon cancer may benefit from adjuvant chemotherapy, but identifying this patient population can be difficult. We assessed the prognosis value for predicting tumor progression in patients with stage II colon cancer, of a panel of 2 biomarkers for colon cancer: tumor budding and preoperative carcinoembryonic antigen (CEA). Consecutive patients (N = 134) with stage II colon cancer who underwent curative surgery from 2000 to 2007 were included. Multivariate analysis was used to evaluate the association of CEA and tumor budding grade with 5-year disease-free survival (DFS). The prognostic accuracy of CEA, tumor budding grade and the combination of both (CEA-budding panel) was determined. The study found that both CEA and tumor budding grade were associated with 5-year DFS. The prognostic accuracy for disease progression was higher for the CEA-budding panel (82.1%) than either CEA (70.9%) or tumor budding grade (72.4%) alone. The findings indicate that the combination of CEA levels and tumor budding grade has greater prognostic value for identifying patients with stage II colon cancer who are at high-risk for disease progression, than either marker alone.

    This study aimed to investigate the outcome for stage II and III rectal cancer patients compared to stage II and III colonic cancer patients with regard to 5-year cause-specific survival (CSS), overall survival, and local and combined recurrence rates over time. This prospective cohort study identified 3,355 consecutive patients with adenocarcinoma of the colon or rectum and treated in our colorectal unit between 1981 and 2011, for investigation. The study was restricted to International Union Against Cancer (UICC) stages II and III. Postoperative mortality and histological incomplete resection were excluded, which left 995 patients with colonic cancer and 726 patients with rectal cancer for further analysis. Five-year CSS rates improved for colonic cancer from 65.0% for patients treated between 1981 and 1986 to 88.1% for patients treated between 2007 and 2011. For rectal cancer patients, the respective 5-year CSS rates improved from 53.4% in the first observation period to 89.8% in the second one. The local recurrence rate for rectal cancer dropped from 34.2% in the years 1981-1986 to 2.1% in the years 2007-2011. In the last decade of observation, prognosis for rectal cancer was equal to that for colon cancer (CSS 88.6 vs. 86.7%, p = 0.409). Survival of patients with colon and rectal cancer has continued to improve over the last three decades. After major changes in treatment strategy including introduction of total mesorectal excision and neoadjuvant (radio)chemotherapy, prognosis for stage II and III rectal cancer is at least as good as for stage II and III colonic cancer.

    In a naturalistic clinical study of patients in the early stages of bipolar disorders the aim was to assess differences between patients with bipolar I (BD I) and bipolar II (BD II) disorders on clinical characteristics including affective symptoms, subjective cognitive complaints, functional level, the presence of comorbid personality disorders and coping strategies. Diagnoses were confirmed using the Structured Clinical Interview for DSM-IV Disorders. Clinical symptoms were rated with the Young Mania Rating Scale and the Hamilton Depression Rating Scale, and functional status using the Functional Assessment Short Test. Cognitive complaints were assessed using the Massachusetts General Hospital Cognitive and Physical Functioning Questionnaire, the presence of comorbid personality disorders using the Standardized Assessment of Personality - Abbreviated Scale and coping style using the Coping Inventory for Stressful Situations. In total, 344 patients were included (BD I (n=163) and BD II (n=181). Patients with BD II presented with significantly more depressive symptoms, more cognitive complaints, lower overall functioning, and a higher prevalence of comorbid personality disorders. Finally, they exhibited a trend towards using less adaptive coping styles. It cannot be omitted that some patients may have progressed from BD II to BD I. Most measures were based on patient self report. Overall, BD II was associated with a higher disease burden. Clinically, it is important to differentiate BD II from BD I and research wise, there is a need for tailoring and testing specific interventions towards BD II. Copyright © 2016 Elsevier B.V.

    2011-01-01

    Background The current study sought to compare levels of overprotection and parenting stress reported by caregivers of children with disorders of sex development at four different developmental stages. Methods Caregivers (N = 59) of children with disorders of sex development were recruited from specialty clinics and were asked to complete the Parent Protection Scale and Parenting Stress Index/Short Form as measures of overprotective behaviors and parenting stress, respectively. Results Analyses of covariance (ANCOVAs) were conducted to examine differences between caregiver report of overprotection and parenting stress. Results revealed that caregivers of infants and toddlers exhibited more overprotective behaviors than caregivers of children in the other age groups. Further, caregivers of adolescents experienced significantly more parenting stress than caregivers of school-age children, and this effect was driven by personal distress and problematic parent-child interactions, rather than having a difficult child. Conclusions These results suggest that caregivers of children with disorders of sex development may have different psychosocial needs based upon their child's developmental stage and based upon the disorder-related challenges that are most salient at that developmental stage.

    Although Aboriginal adults have a higher risk of end-stage renal disease than non-Aboriginal adults, the incidence and causes of end-stage renal disease among Aboriginal children and young adults are not well described. We calculated age- and sex-specific incidences of end-stage renal disease among Aboriginal people less than 22 years of age using data from a national organ failure registry. Incidence rate ratios were used to compare rates between Aboriginal and white Canadians. To contrast causes of end-stage renal disease by ethnicity and age, we calculated the odds of congenital diseases, glomerulonephritis and diabetes for Aboriginal people and compared them with those for white people in the following age strata: 0 to less than 22 years, 22 to less than 40 years, 40 to less than 60 years and older than 60 years. Incidence rate ratios of end-stage renal disease for Aboriginal children and young adults (age diseases were less common among Aboriginal people aged less than 22 years (odds ratio [OR] 0.56, 95% CI 0.36-0.86), and glomerulonephritis was more common (OR 2.18, 95% CI 1.55-3.07). An excess of glomerulonephritis, but not diabetes, was seen among Aboriginal people aged 22 to less than 40 years. The converse was true (higher risk of diabetes, lower risk of glomerulonephritis) among Aboriginal people aged 40 years and older. The incidence of end-stage renal disease is higher among Aboriginal children and young adults than among white children and young adults. This higher incidence may be driven by an increased risk of glomerulonephritis in this population.

    1981-01-01

    Three treatment programs for Stage I and II mediastinal Hodgkin disease (established by laparotomy) were compared. Involved-field radiotherapy + MOPP gave a disease-free survival rate of 97%, significantly different from 62% and 55% for involved and extended fields, respectively. Corresponding survival figures of 97%, 88%, and 84% were not signiticantly different statistically due to salvage with radiotherapy and/or chemotherapy. Among patients given radiotherapy alone, the survival figure of 94% for limited mediastinal disease was significantly better than 63% for extensive mediastinal and hilar disease; corresponding disease-free figures of 72% and 35% were also significantly different. Constitutional symptoms were an important prognostic factor in disease-free survival following the use of involved fields; hilar disease was important only with large mediastinal masses. Most relapses were intrathoracic; MOPP alone salvaged only 47%. Treatment of State I and II Hodgkin disease should be based on symptoms, extent of mediastinal disease, and hilar involvement

    We wanted to determine the clinical characteristics and prognosis according to the VEGF expression in stage II cervical carcinoma patients treated with definitive radiotherapy. We enrolled 31 patients who were diagnosed with cervical cancer from 1995 to 2003 at Samsumg Medical Center and their paraffin block tissue samples were available for study. The median age of the patients was 65 years. The mean tumor size was 4.1 cm (range: 1.2 ∼8.2 cm). Seven patients (22.6%) were suspected of having pelvic lymph node metastasis. An external beam irradiation dose of 45-56.4 Gy was administered to the whole pelvis with a 15 MV linear accelerator, and an additional 24 Gy was given to point A by HDR intracavitary brachytherapy. VEGF staining was defined as positive when more than 10% of the tumor cells were stained. The median follow-up duration was 58 months. A positive VEGF expression was observed in 21 patients (67.7%). There was no significant correlation between the VEGF expression and pelvic lymph node metastasis, tumor size and the response of radiotherapy. During follow-up, 7 patients had recurrence. The complete response rate was not significant between the VEGF (-) and VEGF(+) tumors. However, the VEGF(+) tumors showed a significantly higher recurrence rate in comparison with the VEGF(-) tumors (ρ = 0.040). The three year disease-free survival rates were 100% and 66.7%, respectively, for patients with VEGF(-) or VEGF(+) tumor (ρ = 0.047). The VEGF expression was a significant factor for recurrence and disease-free survival. However, the significance of the VEGF expression is still controversial because of the various definitions of VEGF expression and the mismatches of the clinical data in the previous studies

    Time to onset of stage II lactogenesis varies widely, and delayed onset of lactogenesis (OL) is common among first-time mothers in the United States. Higher body mass index, older age, and larger infant birth weight are identified risk factors for delayed OL; all are known correlates with glucose metabolism. Our objective was to prenatally assess maternal biomarkers related to metabolic health and determine the extent to which these biomarkers predict timing of OL. We enrolled a population-based sample of expectant primiparas attending a single prenatal clinic. We obtained a blood sample 1-hour post-glucose load from an antenatal oral glucose challenge test and assayed for the following biomarkers: serum insulin, glucose, adiponectin, leptin, C-reactive protein, interleukin-6, resistin, and tumor necrosis factor-α. Our outcome measure was timing of OL, based on maternal report at 3-5 days postpartum. We used linear regression to model OL hour. Twenty-six of 29 (90%) agreed to screening, 18 delivered at term and initiated breastfeeding, and 16 have complete data. Median (minimum-maximum) postpartum body mass index was 27.4 (21.8-34.7) kg/m(2), and median time to OL was 64 (10-121) hours. The model, OL = 232 - 34.9(ln[ratio insulin/glucose]) - 1.4(adiponectin), explained 56% of the variation in OL hour (p = 0.005) and was not weakened by potential confounders. Higher serum insulin secretion relative to serum glucose after a glucose challenge and higher serum adiponectin are associated with earlier onset of OL. These findings suggest that factors associated with better glucose tolerance predict earlier OL.

    Two lines of psychological research have attempted to spell out the stages of adolescent smoking initiation. The first has focused on behavioral stages of smoking initiation, while the second line emphasized motivational stages. A large international sample of European adolescents (N = 10,170, mean age = 13.3 years) was followed longitudinally. Self-reported motivational and behavioral stages of smoking initiation were integrated, leading to the development of the Model of Unplanned Smoking Initiation of Children and Adolescents (MUSICA). The MUSICA postulates that youngsters experiment with smoking while they are in an unmotivated state as regards their plans for smoking regularly in the future. More than 95% of the total population resided in one of the seven stages distinguished by MUSICA. The probability of starting to smoke regularly during the 12 months follow-up period increased with advanced stage assignment at baseline. Unique social cognitive predictors of stage progression from the various stages were identified, but effect sizes of predictors of transitions were small. The integration of motivational and behavioral dimensions improves our understanding of the process of smoking initiation. In contrast to current theories of smoking initiation, adolescent uptake of smoking behavior was found to be an unplanned action.

    Full Text Available Autobiographical memory (AM is a highly constructive cognitive process that often contains memory errors. No study has specifically examined AM accuracy in children with abnormal development of the hippocampus, a crucial brain region for AM retrieval. Thus, the present study investigated AM accuracy in 68 typically and atypically developing children using a staged autobiographical event, the Children's Autobiographical Interview, and structural magnetic resonance imaging. The atypically developing group consisted of 17 children (HYPO exposed during gestation to insufficient maternal thyroid hormone (TH, a critical substrate for hippocampal development, and 25 children with congenital hypothyroidism (CH, who were compared to 26 controls. Groups differed significantly in the number of accurate episodic details recalled and proportion accuracy scores, with controls having more accurate recollections of the staged event than both TH-deficient groups. Total hippocampal volumes and anterior hippocampal volumes were positively correlated with proportion accuracy scores, but not total accurate episodic details, in HYPO and CH. In addition, greater severity of TH deficiency predicted lower proportion accuracy scores in both HYPO and CH. Overall, these results indicate that children with early TH deficiency have deficits in AM accuracy and that the anterior hippocampus may play a particularly important role in accurate AM retrieval.

    Purpose: Mucosa-associated lymphoid tissue (MALT) lymphoma is a distinct disease with specific clinical and pathologic features that may affect diverse organs. We analyzed our recent experience with Stage I/II MALT lymphoma presenting in the stomach and other organs to assess the outcome following involved field radiation therapy (RT). Patients and Methods: Seventy patients with Stage IE (62) and IIE (8) disease were treated between 1989 and 1998. Patients with transformed MALT were excluded. The median age was 62 years (range, 24-83 years), M:F ratio 1:2.2. Presenting sites included stomach, 15; orbital adnexa, 19; salivary glands, 15; thyroid, 8; lung, 5; upper airways, 3 (nasopharynx, 2; larynx, 1); urinary bladder, 3; breast, 1; and rectum, 1. Staging included site-specific imaging, CT abdomen in 66 patients (94%) and bone marrow biopsy in 54 (77%). Sixty-two patients received radiation therapy: 52 received RT alone, 7 received chemotherapy and RT, and 3 received antibiotics followed by RT. Median RT dose was 30 Gy (range, 17.5-35 Gy). Most frequently used RT prescriptions were 25 Gy (26 patients--18 orbit, 6 stomach, and 2 salivary glands), 30 Gy (23 patients), and 35 Gy (8 patients). Five patients had complete surgical excision of lymphoma and no other treatment (stomach 1, salivary 2, lung 2), whereas 2 patients with gastric lymphoma received antibiotics only. One patient refused treatment and was excluded from the analysis of treatment outcome, leaving 69 patients with a median follow-up of 4.2 years (range, 0.3-11.4 years). Results: A complete response was achieved in 66/69 patients, and 3 patients had partial response (2 lung, 1 orbit). The 5-year disease-free survival (DFS) was 76%, and the overall survival was 96%. No relapses were observed in patients with stomach and thyroid lymphoma. The 5-year DFS for these patients was 93%, in contrast to 69% for patients presenting in other sites (p 0.006). Among the 5 patients treated with surgery only, 2

    Clinical data indicate that prognostic stratification of radically resected colorectal cancer based on disease stage only may not be always be adequate. Preclinical findings suggest that cancer stem cells may influence the biological behaviour of colorectal cancer independently from stage: objective of the study was to assess whether a panel of stemness markers were correlated with clinical outcome in resected stage II and III colon cancer patients. A panel of 66 markers of stemness were analysed and thus patients were divided into two groups (A and B) with most patients clustering in a manner consistent with different time to relapse by using a statistical algorithm. A total of 62 patients were analysed. Thirty-six (58%) relapsed during the follow-up period (range 1.63-86.5 months). Twelve (19%) and 50 (81%) patients were allocated into group A and B, respectively. A significantly different median relapse-free survival was observed between the 2 groups (22.18 vs 42.85 months, p=0.0296). Among of all genes tested, those with the higher "weight" in determining different prognosis were CD44, ALCAM, DTX2, HSPA9, CCNA2, PDX1, MYST1, COL1A1 and ABCG2. This analysis supports the idea that, other than stage, biological variables, such as expression levels of colon cancer stem cell genes, may be relevant in determining an increased risk of relapse in resected colorectal cancer patients.

    Purpose: To evaluate the survival impact of postoperative radiation therapy (PORT) in stage II to IV thymomas, using systematic review and meta-analysis. Methods and Materials: A database search was conducted with EMBASE, PubMed, Web of Science, Cochrane Library, and Ovid from inception to August 2015. Thymic carcinomas were excluded, and studies comparing overall survival (OS) with and without PORT in thymomas were included. The hazard ratios (HRs) of OS were extracted, and a random-effects model was used in the pooled analysis. Results: Seven retrospective series with a total of 1724 patients were included and analyzed. Almost all of the patients underwent macroscopically complete resection, and thymoma histology was confirmed by the World Health Organization criteria. In the overall analysis of stage II to IV thymomas, OS was not altered with the receipt of PORT (HR 0.79, 95% confidence interval [CI] 0.58-1.08). Although PORT was not associated with survival difference in Masaoka stage II disease (HR 1.45, 95% CI 0.83-2.55), improved OS was observed with the addition of PORT in the discrete pooled analysis of stage III to IV (HR 0.63, 95% CI 0.40-0.99). Significant heterogeneity and publication bias were not found in the analyses. Conclusions: From the present meta-analysis of sole primary thymomas, we suggest the potential OS benefit of PORT in locally advanced tumors with macroscopically complete resection, but not in stage II disease. Further investigations with sufficient survival data are needed to establish detailed treatment indications.

    Estimation of the protein levels introduced in a biotechnology-derived product is conducted as part of an overall safety assessment. An enzyme-linked immunosorbent assay (ELISA) was used to analyze phosphinothricin acetyltransferase (PAT) and neomycin phosphotransferase II (NPT II) protein expression in a genetically modified (GM) pepper plant developed in Korea. PAT and NPT II expression levels, based on both dry weight and fresh weight, were variable among different plant generations and plant sections from isolated genetically modified organism (GMO) fields at four developmental stages. PAT expression was highest in leaves at anthesis (11.44 μg/gdw and 2.17 μg/gfw) and lowest in roots (0.12 μg/gdw and 0.01 μg/gfw). NPT II expression was also highest in leaves at anthesis (17.31 μg/gdw and 3.41 μg/gfw) and lowest in red pepper (0.65 μg/gdw and 0.12 μg/gfw). In pollen, PAT expression was 0.59-0.62 μg/gdw, while NPT II was not detected. Both PAT and NPT II showed a general pattern of decreased expression with progression of the growing season. As expected, PAT and NPT II protein expression was not detectable in control pepper plants.

    Acetylenic fatty acids are known to display several biological activities, but their antimalarial activity has remained unexplored. In this study, we synthesized the 2-, 5-, 6-, and 9-hexadecynoic acids (HDAs) and evaluated their in vitro activity against erythrocytic (blood) stages of Plasmodium falciparum and liver stages of Plasmodium yoelii infections. Since the type II fatty acid biosynthesis pathway (PfFAS-II) has recently been shown to be indispensable for liver stage malaria parasites, the inhibitory potential of the HDAs against multiple P. falciparum FAS-II (PfFAS-II) elongation enzymes was also evaluated. The highest antiplasmodial activity against blood stages of P. falciparum was displayed by 5-HDA (IC(50) value 6.6 μg/ml), whereas the 2-HDA was the only acid arresting the growth of liver stage P. yoelii infection, in both flow cytometric assay (IC(50) value 2-HDA 15.3 μg/ml, control drug atovaquone 2.5 ng/ml) and immunofluorescence analysis (IC(50) 2-HDA 4.88 μg/ml, control drug atovaquone 0.37 ng/ml). 2-HDA showed the best inhibitory activity against the PfFAS-II enzymes PfFabI and PfFabZ with IC(50) values of 0.38 and 0.58 μg/ml (IC(50) control drugs 14 and 30 ng/ml), respectively. Enzyme kinetics and molecular modeling studies revealed valuable insights into the binding mechanism of 2-HDA on the target enzymes. All HDAs showed in vitro activity against Trypanosoma brucei rhodesiense (IC(50) values 3.7-31.7 μg/ml), Trypanosoma cruzi (only 2-HDA, IC(50) 20.2 μg/ml), and Leishmania donovani (IC(50) values 4.1-13.4 μg/ml) with generally low or no significant toxicity on mammalian cells. This is the first study to indicate therapeutic potential of HDAs against various parasitic protozoa. It also points out that the malarial liver stage growth inhibitory effect of the 2-HDA may be promoted via PfFAS-II enzymes. The lack of cytotoxicity, lipophilic nature, and calculated pharmacokinetic properties suggests that 2-HDA could be a useful compound to

    Full Text Available The paper gives the data available in the literature, which reflect the manifestations, diagnosis, and current treatments of the rare (orphan inherited disease glycogen storage disease type II or Pomp disease in children, as well as its classification. The infant form is shown to be most severe, resulting in death from cardiovascular or pulmonary failure generally within the first year of a child’s life. Emphasis is laid on major difficulties in the differential and true diagnosis of this severe disease. Much attention is given to the new pathogenetic treatment — genetically engineered enzyme replacement drug Myozyme®. The authors describe their clinical case of a child with the juvenile form of glycogen storage disease type II (late-onset Pompe disease. Particular emphasis is laid on the clinical symptoms of the disease and its diagnostic methods, among which the morphological analysis of a muscle biopsy specimen by light and electron microscopies, and enzyme and DNA diagnoses are of most importance. The proband was found to have significant lysosomal glycogen accumulation in the muscle biopsy specimen, reduced lymphocyte acid α-1,4-glucosidase activity to 4,2 nM/mg/h (normal value, 13,0—53,6 nM/mg/h, described in the HGMD missense mutation database from 1000 G>A p.Gly334er of the GAA in homozygous state, which verified the diagnosis of Pompe disease.

    Sleep inertia refers to impairments in cognitive/motor performance and the tendency to return to sleep after awakening. As part of a project studying the effect of different types of 100 decibel (dB) sounds on awakening children during stage 4 sleep (S4S), we hypothesized that children with the greatest impairment in auditory arousal during S4S, manifested by the inability to either awaken to 100 dB sounds or successfully perform a self-rescue sequence (SRS), would have greater impairments in reaction time (RT) upon awakening than children who awoke and successfully accomplish a SRS. Observational study. Pediatric hospital-based sleep center. Healthy children aged 6-12 years. N/A. RT was measured in 44 children approximately 90 minutes before bedtime and again after awakening by either 100 dB alarms or manually during the first and second cycles of S4S. Overall, mean and median RT slowed significantly by 37% and 22%, respectively, from baseline. Slowing of RT was most evident in the youngest children (aged 6-7 years) and after awakening from the second S4S cycle. Impairments in RT were not significantly different among children who successfully awakened to the alarm and performed a SRS compared with children who did not. The degree of slowing of RT was not significantly different among children who awakened and performed an SRS compared with children who did not. The greatest slowing of RT was seen among younger children and after awakening from the second S4S cycle.

    Adult patients with chronic kidney disease are at risk of major neurologic and cardiac complications. The purpose of this study is to review the neurological and cardiac complications in children with end-stage renal disease (ESRD). A retrospective review of medical records of children with ESRD at Jordan University Hospital was performed. All neurological and cardiac events were recorded and analyzed. Data of a total of 68 children with ESRD presenting between 2002 and 2013 were reviewed. Neurological complications occurred in 32.4%; seizures were the most common event. Uncontrolled hypertension was the leading cause of neurological events. Cardiac complications occurred in 39.7%, the most common being pericardial effusion. Mortality from neurological complications was 45%. Neurological and cardiac complications occurred in around a third of children with ESRD with a high mortality rate. More effective control of hypertension, anemia, and intensive and gentle dialysis are needed.

    The second stage of a Boeing Delta II rocket begins its move up the tower at Pad 17A, Cape Canaveral Air Station, for mating with the first stage. The rocket is targeted for launch on Feb. 6, carrying the Stardust spacecraft into space for a close encounter with the comet Wild 2 in January 2004. Using a substance called aerogel, Stardust will capture comet particles flying off the nucleus of the comet, plus collect interstellar dust for later analysis. The collected samples will return to Earth in a sample return capsule to be jettisoned as Stardust swings by Earth in January 2006.

    BACKGROUND: Angiogenesis plays a pivotal role in malignant tumour growth and the metastatic process. We analysed the prognostic value of two angiogenesis parameters, microRNA-126 (miRNA-126) and microvessel density (MVD), in a population based cohort of patients operated for stage II colon cancer...... = 0.051. The MVD estimate was not associated with either RF-CSS, p = 0.49, or OS, p = 0.94. CONCLUSION: The current population based study of patients operated for stage II colon cancer demonstrated correlations between several prognostic unfavourable characteristics and miRNA-126 and argues...... were correlated with recurrence-free cancer specific survival (RF-CSS) and overall survival (OS). RESULTS: Low miRNA-126 expression was significantly correlated to T4, high malignancy grade, tumour perforation, fixation, and the presence of microsatellite instability.

    CT is currently the mainstay in staging malignant lymphoma in children, but the risk of second neoplasms due to ionizing radiation associated with CT is not negligible. Whole-body MRI techniques and whole-body diffusion-weighted imaging (DWI) in particular, may be a good radiation-free alternative to CT. DWI is characterized by high sensitivity for the detection of lesions and allows quantitative assessment of diffusion that may aid in the evaluation of malignant lymphomas. This article will review whole-body MRI techniques for staging malignant lymphoma with emphasis on whole-body DWI. Furthermore, future considerations and challenges in whole-body DWI will be discussed. (orig.)

    Early diagnosis of gallbladder cancer (GBC) can remarkably improve the prognosis of patients. This study aimed to develop a nomogram for individualized diagnosis of stage I-II GBC in chronic cholecystitis patients with gallbladder wall thickening. The nomogram was developed using logistic regression analyses based on a retrospective cohort consisting of 89 consecutive patients with stage I-II GBC and 1240 patients with gallbladder wall thickening treated at one biliary surgery center in Shanghai between January 2009 and December 2011. The accuracy of the nomogram was validated by discrimination, calibration and a prospective cohort treated at another center between January 2012 and December 2014 (n=928). Factors included in the nomogram were advanced age, hazardous alcohol consumption, long-standing diagnosed gallstones, atrophic gallbladder, gallbladder wall calcification, intraluminal polypoid lesion, higher wall thickness ratio and mucosal line disruption. The nomogram had concordance indices of 0.889 and 0.856 for the two cohorts, respectively. Internal and external calibration curves fitted well. The area under the receiver-operating characteristic curves of the nomogram was higher than that of multidetector row computed tomography in diagnosis of stage I-II GBC (Pcholecystitis patients with gallbladder wall thickening, especially for those the imaging features alone do not allow to confirm the diagnosis.

    Diabetes is a risk factor for colorectal cancer and several reports suggest worse cancer-specific outcomes in diabetes patients. Recent studies in multiple tumour types indicate metformin may positively impact on cancer-specific and overall survival. A population-based series of stage II colorectal cancer patients treated and followed from 2000 to 2013 were analysed for baseline characteristics, treatment, and outcomes. 1116 patients with stage II colon cancer were identified, 55.5% were male and median age was 70.9 years (range 20.5-101.2). The diabetes patients (21.6%, n = 241) were older than nondiabetes patients (median 74.0 versus 69.6, p = 0.0001). There was no impact of diabetes on cancer presentation or pathology. Diabetes patients were less likely to receive adjuvant treatment (13.7 versus 24.8%, p = 0.002) but were equally likely to complete treatment (69.7 versus 67.7%, p = 1.00). Diabetes did not significantly impact cancer recurrence (HR = 1.07, 95% CI 0.71-1.63) or overall survival (HR = 1.23, 95% CI 0.88-1.72), adjusted for age. Diabetes medication did not impact cancer recurrence or survival. Cancer presentation and outcomes in diabetes patients are comparable to those of nondiabetes patients in those with stage II colon cancer. The effect of metformin merits further evaluation in patients with colon cancer.

    The value of strengthening and stretching exercises combined with orthosis treatment in a home-based program has not been evaluated. The purpose of this study was to compare the effects of augmenting orthosis treatment with either stretching or a combination of stretching and strengthening in participants with stage II tibialis posterior tendon dysfunction (TPTD). Participants included 39 patients with stage II TPTD who were recruited from a medical center and then randomly assigned to a strengthening or stretching treatment group. Excluding 3 dropouts, there were 19 participants in the strengthening group and 17 in the stretching group. The stretching treatment consisted of a prefabricated orthosis used in conjunction with stretching exercises. The strengthening treatment consisted of a prefabricated orthosis used in conjunction with the stretching and strengthening exercises. The main outcome measures were self-report (ie, Foot Function Index and Short Musculoskeletal Function Assessment) and isometric deep posterior compartment strength. Two-way analysis of variance was used to test for differences between groups at 6 and 12 weeks after starting the exercise programs. Both groups significantly improved in pain and function over the 12-week trial period. The self-report measures showed minimal differences between the treatment groups. There were no differences in isometric deep posterior compartment strength. A moderate-intensity, home-based exercise program was minimally effective in augmenting orthosis wear alone in participants with stage II TPTD.

    Adjuvant chemotherapy for stage II colon cancer is a controversial practice and is not recommended by the French Consensus Conference outside of therapeutic trial. To assess, within a well-defined population, the influence of hospital characteristics in this practice. In the Rhône-Alpes region (10% of the French population), 534 patients presenting with colon cancer stage II were operated on in 81 hospitals in the year 2000. The influence of hospital characteristics on the use of adjuvant chemotherapy was assessed using a multivariate logistic regression. Overall, 19.5% of patients received adjuvant chemotherapy. Younger age, T4 tumour, hospital volume lower than 20 colon cancer surgeries [odds ratio (OR) 2.96; Pclinical complications at diagnosis were independently associated with higher rates of chemotherapy. On the other hand, a number of examined lymph nodes lower than recommendations did not have any influence on chemotherapy use. Hospital characteristics had independently influenced the practice of adjuvant chemotherapy in stage II colon cancer. The more important institutional factor was the hospital procedure volume. The decisions of the multidisciplinary committees appeared at times paradoxical; a more comprehensive evaluation of this practice is needed.

    Purpose: To analyze retrospectively the outcome of postoperative radiation therapy with or without concurrent chemotherapy for curatively resected stage II pancreatic cancer with T3 or N1 disease. Materials and Methods: Between January 1996 and December 2005, twenty-eight patients completed adjuvant radiation therapy at Ajou University Hospital. The patients had either pathologic T3 stage or N1 stage. The radiation target volume encompassed the initial tumor bed identified preoperatively, resection margin area and celiac nodal area. In the case of N1 patients, the radiation field extended to the lower margin of the L3 vertebra for covering both para-aortic lymph nodes bearing area. The median total radiation dose was 50 Gy. Ten patients received concurrent chemotherapy. Results: Thirteen patients (46%) showed loco-regional recurrences. The celiac axis nodal area was the most frequent site (4 patients). Five patients showed both loco-regional recurrence and a distant metastasis. Patients with positive lymph nodes had a relatively high probability of a distant metastasis (57.1%). Patients that had a positive resection margin showed a relatively high local failure rate (57.1%). The median disease-free survival period of all patients was 6 months and the 1- and 2-year disease free survival rates were 27.4% and 8.2%, respectively. The median overall survival period was 9 months. The 2- and 3-year overall survival rates were 31.6% and 15.8%, respectively. Conclusion: The pancreatic cancer patients with stage II had a high risk of local failure and a high risk of a distant metastasis. We suggest the concurrent use of an effective radiation-sensitizing chemotherapeutic drug and adjuvant chemotherapy after postoperative radiation therapy for the treatment of patients with stage II pancreatic cancer.

    Full Text Available Abstract Background Actual caries figures emphasize the need to identify the risk indicators involved in the disease’s development. The hypothesis that certain risk indicators might affect the dynamic evolution of the caries process was assessed; to clarify this premise, a cross-sectional survey was performed in school children. Methods A total of 390 subjects aged 6–8 years old were randomly selected. Caries was assessed, and the subjects were stratified as follows: i highest caries score; ii most prevalent caries score; and iii number of affected teeth. Parents/guardians completed a questionnaire regarding vital statistics, socio-economic indicators, dietary habits, oral hygiene habits and oral health behaviours. Results Caries was detected in 42.31% of the subjects. Maternal nationality, parental education level, use of a sweetened pacifier at night, intake of lactose-free milk and toothbrushing frequency were statistically significant associated (p < 0.05 with subjects stratified according to the highest caries score. Parental educational level, maternal occupational status and use of a sweetened pacifier at night were associated (p < 0.05 with affected children stratified according to the most prevalent caries score. Maternal educational level and intake of lactose-free milk were associated with subjects with moderate caries stages compared to being caries-free (p = 0.01 and p = 0.02, respectively. Maternal nationality (p < 0.01 and toothbrushing frequency (p = 0.01 were associated with subjects affected by extensive lesions compared to caries-free children. In subjects affected by initial lesions as the most prevalent figure, gender (male and paternal occupation status (unemployed were statistically significant associated (p = 0.03 and p = 0.04, respectively compared to those affected by highest prevalence of extensive caries lesions.

    Chemicals targeting the liver stage (LS) of the malaria parasite are useful for causal prophylaxis of malaria. In this study, four lichen metabolites, evernic acid (1), vulpic acid (2), psoromic acid (3), and (+)-usnic acid (4), were evaluated against LS parasites of Plasmodium berghei. Inhibition of P. falciparum blood stage (BS) parasites was also assessed to determine stage specificity. Compound 4 displayed the highest LS activity and stage specificity (LS IC50 value 2.3 μM, BS IC50 value 47.3 μM). The compounds 1-3 inhibited one or more enzymes (PfFabI, PfFabG, and PfFabZ) from the plasmodial fatty acid biosynthesis (FAS-II) pathway, a potential drug target for LS activity. To determine species specificity and to clarify the mechanism of reported antibacterial effects, 1-4 were also evaluated against FabI homologues and whole cells of various pathogens (S. aureus, E. coli, M. tuberculosis). Molecular modeling studies suggest that lichen acids act indirectly via binding to allosteric sites on the protein surface of the FAS-II enzymes. Potential toxicity of compounds was assessed in human hepatocyte and cancer cells (in vitro) as well as in a zebrafish model (in vivo). This study indicates the therapeutic and prophylactic potential of lichen metabolites as antibacterial and antiplasmodial agents.

    Pelvic organ prolapse (POP) is a prevalent disorder which seriously affects the sufferer's quality of life. The main goal of this study was to evaluate biofeedback impact on quality of life in women with mild to moderate POP. 40 females in stages I and II POP were allocated into 2 groups. One group received pelvic floor muscle exercise and lifestyle advice in addition to biofeedback twice a week for 4 weeks, while the other received a lifestyle advice sheet and pelvic floor muscle exercise without biofeedback. A valid Persian version of P-QOL questionnaire was applied to assess the patients̕ quality of life at baseline, 4 weeks and 12 weeks follow up. Pressure biofeedback and Physical examination were also performed in order to determine pelvic floor muscle strength and staging of the prolapse, respectively. Collected data were analyzed by mixed ANOVA test using SPSS 22. Biofeedback improved the quality of life in seven of nine P-QOL domains. However, it had no significant impact either on pelvic floor muscle strength or on the stage of the prolapse. Biofeedback could be considered as a non-invasive treatment leading to quality of life promotion in women with stages I and II POP. Copyright © 2017 Elsevier B.V. All rights reserved.

    Non-alcoholic fatty liver disease (NAFLD) has become one of the most frequent causes of chronic liver disease. Currently, therapeutic options for NAFLD patients are limited, but new pharmacologic agents are being investigated in the course of clinical trials. Because most of these studies are focusing on patients with fibrosis stages II and III (according to Kleiner), non-invasive identification of patients with intermediate fibrosis stages (II and III) is of increasing interest. Evaluation of NAFLD Fibrosis Score (NFS) and liver stiffness measurement (LSM) for prediction of fibrosis stages II/III. Patients with histologically confirmed NAFLD diagnosis were included in the study. All patients underwent a clinical and laboratory examination as well as a LSM prior to liver biopsy. Predictive value of NFS and LSM with respect to identification of fibrosis stages II/III was assessed. 134 NAFLD patients were included and analyzed. Median age was 53 (IQR 36 - 60) years, 55 patients (41 %) were female. 82 % of our patients were overweight/obese with typical aspects of metabolic syndrome. 84 patients (66 %) had liver fibrosis, 42 (50 %) advanced fibrosis. LSM and NFS correlated with fibrosis stage (r = 0.696 and r = 0.685, respectively; p stages II/III. If both criteria were met, probability of fibrosis stage II/III was 61 %. If none of the two criteria was met, chance for fibrosis stage II/III was only 6 % (negative predictive value 94 %). Combination of LSM and NFS enables identification of patients with significant probability of fibrosis stage II/III. Accordingly, these tests, especially in combination, may be a suitable screening tool for fibrosis stages II/III in NAFLD. The use of these non-invasive methods might also help to avoid unnecessary biopsies. © Georg Thieme Verlag KG Stuttgart · New York.

    Decisions regarding adjuvant therapy in patients with stage II colorectal cancer (CRC) have been among the most challenging and controversial in oncology over the past 20 years. To develop robust combinatory cancer hallmark-based gene signature sets (CSS sets) that more accurately predict prognosis and identify a subset of patients with stage II CRC who could gain survival benefits from adjuvant chemotherapy. Thirteen retrospective studies of patients with stage II CRC who had clinical follow-up and adjuvant chemotherapy were analyzed. Respective totals of 162 and 843 patients from 2 and 11 independent cohorts were used as the discovery and validation cohorts, respectively. A total of 1005 patients with stage II CRC were included in the 13 cohorts. Among them, 84 of 416 patients in 3 independent cohorts received fluorouracil-based adjuvant chemotherapy. Identification of CSS sets to predict relapse-free survival and identify a subset of patients with stage II CRC who could gain substantial survival benefits from fluorouracil-based adjuvant chemotherapy. Eight cancer hallmark-based gene signatures (30 genes each) were identified and used to construct CSS sets for determining prognosis. The CSS sets were validated in 11 independent cohorts of 767 patients with stage II CRC who did not receive adjuvant chemotherapy. The CSS sets accurately stratified patients into low-, intermediate-, and high-risk groups. Five-year relapse-free survival rates were 94%, 78%, and 45%, respectively, representing 60%, 28%, and 12% of patients with stage II disease. The 416 patients with CSS set-defined high-risk stage II CRC who received fluorouracil-based adjuvant chemotherapy showed a substantial gain in survival benefits from the treatment (ie, recurrence reduced by 30%-40% in 5 years). The CSS sets substantially outperformed other prognostic predictors of stage 2 CRC.

    Full Text Available Purpose : theoretical and methodological justification for the existing teaching methods tennis of 5-6 years old children. Material : 17 special analysis and scientific and methodological sources. Results : the features of the existing methods of teaching children at an early stage of training. The main theses of the existing methods: 1 the training process is carried out in the form of games; 2 the level of general physical preparedness level exceeds special; 3 The first two years of the children do not participate in official competitions; 4 education of children begins with " School Ball ", with a gradual transition to employment with racket and ball; 5 training is built on two levels: theoretical - each " part" in the form of pre- formation of a mental model of rational behavior, and practical - the formation of the ability to perform motor actions. Conclusions : it was found that the existing methods of constructing the training process for children 5-6 years do not account for their physiological characteristics, therefore proposed to use computer technology and animation, that will shorten the formation of motor skills of children.

    Purpose: To evaluate the prognostic importance of T classification and maximum tumor thickness (MTT) on the treatment results of Stage I and II oral tongue cancer treated with interstitial brachytherapy. Methods and Materials: Between January 1981 and December 1993, 173 cases were eligible for this retrospective analysis. Of 173 patients, 75 were classified as Stage I and 98 as Stage II: maximum tumor length ranged from 6 to 40 mm. MTT, which ranged from 2 to 38 mm, was measured with ultrasonography and/or palpation. Brachytherapy was performed with iridium hairpins or radium needles following external irradiation in 66 patients, or exclusively in 107 patients. Results: The 5-year local recurrence rates were Stage I, 7%; Stage II, 22%; MTT < 8 mm, 8%; and MTT ≥ 8 mm, 28%. The 5-year regional recurrence rates were Stage I, 15%; Stage II, 29%; MTT < 8 mm, 18%; and MTT ≥ 8 mm, 31%, respectively. The 5-year local recurrence rates of the patients with Stage I and MTT < 8 mm of the brachytherapy only group were significantly better than those of Stage II and MTT ≥ 8 mm (5% and 6% vs. 16% and 24%). The 5-year regional recurrence rates of the patients with Stage I and MTT < 8 mm of the brachytherapy-only group were significantly better than those of Stage II and MTT ≥ 8 mm (14% and 16% vs. 34% and 46%). There was no significant difference in the 5-year regional recurrence rates between the two groups of Stage I and Stage II, MTT < 8 mm. However, there was a significant difference in the 5-year regional recurrence rates between the two groups of MTT ≥ 8 mm (p < 0.005). Conclusions: For patients with Stage I and II oral tongue cancer, tumor thickness as well as T classification were prognostic for nodal metastasis and prognosis. Patients with MTT ≥ 8 mm are more likely to fail in the neck region. These findings suggest that MTT should be considered along with T stage in determining strategies for Stage I and II oral tongue cancer

    Purpose: To evaluate the role of definitive radiation therapy (RT) in the treatment for medically inoperable patients with stage I-II non-small cell lung cancer (NSCLC). Materials and Methods: From 1976 through 1989, 84 patients with clinical stage I and II NSCLC were treated with definitive RT alone at Gunma University hospital. All patients were treated with 10 MV X-rays using antero-posterior parallel opposed fields. The total dose ranged from 60 Gy to 90 Gy (35 pts; 60-69 Gy, 39 pts; 70-74 Gy, 10 pts; ≥ 80 Gy) with once-daily standard fractionation. Results: The two and five-year survival rates were 74% and 31% for 28 patients with stage I disease, as compared with 40% and 19% for 56 patients with stage II respectively (p<0.05). Although there was no significant difference of survival rates by the histologic subtypes, in the patients with squamous cell carcinoma there were more long-term survivors. Fifty-three patients with tumors less than 5 cm in diameter had an infield progression rate of 14% at two years, in comparison with 38% of 31 patients with tumors greater than 5 cm (p<0.05). Overall distant failure occurred in 57% of the patients with smaller tumors and in 80% of the patients with larger tumors (p<0.05). The difference of survival rates for these two groups was statistically significant (p<0.005). Ten patients given a total dose of 80Gy or over had only 17% local progression at the time of last follow-up, however they had not been alive beyond three years because they developed pulmonary insufficiency due to severe stenosis of the proximal bronchus. For age and sex, there were no significant differences in survival, however, patients with performance status of 0-1 lived longer than those with a status of 2 or more (MST 24 versus 13 months; p=0.06). Conclusion: The tumor size was the most important factor not only for local control but also for distant failure. It was also suggested that the optimal radiation dose for medically inoperable stage I-II

    The rate of failure in phase III oncology trials is surprisingly high, partly owing to inadequate phase II studies. Recently, the use of randomized designs in phase II is being increasingly recommended, to avoid the limits of studies that use a historical control. We propose a two-arm two-stage design based on a Bayesian predictive approach. The idea is to ensure a large probability, expressed in terms of the prior predictive probability of the data, of obtaining a substantial posterior evidence in favour of the experimental treatment, under the assumption that it is actually more effective than the standard agent. This design is a randomized version of the two-stage design that has been proposed for single-arm phase II trials by Sambucini. We examine the main features of our novel design as all the parameters involved vary and compare our approach with Jung's minimax and optimal designs. An illustrative example is also provided online as a supplementary material to this article. Copyright © 2014 John Wiley & Sons, Ltd.

    End-stage renal disease (ESRD) in children is considered a rare, but serious condition. Epidemiological and demographic information on pediatric ESRD patients around the world is important to better understand this disease and to improve patient care. The Japanese Society for Pediatric Nephrology (JSPN) reported epidemiological and demographic data in 1998. Since then, however, there has been no nationwide survey on Japanese children with ESRD. The JSPN conducted a cross-sectional nationwide survey in 2012 to update information on the incidence, primary renal disease, initial treatment modalities, and survival in pediatric Japanese patients with ESRD aged less than 20 years during the period 2006-2011. The average incidence of ESRD was 4.0 per million age-related population. Congenital anomalies of the kidney and urinary tract were the most common cause of ESRD, present in 39.8 % of these patients. In addition, 12.2 % had focal segmental glomerulosclerosis and 5.9 % had glomerulonephritis. Initial treatment modalities in patients who commenced renal replacement therapy (RRT) consisted of peritoneal dialysis, hemodialysis, and pre-emptive transplantation (Tx) in 61.7, 16.0, and 22.3 %, respectively. The Japanese RRT mortality rate was 18.2 deaths per 1000 person-years of observation. The incidence of ESRD is lower in Japanese children than in children of other high-income countries. Since 1998, notably, there has been a marked increase in pre-emptive Tx as an initial treatment modality for Japanese children with ESRD.

    To evaluate the accuracy of self-reported Tanner (SRT) staging against a proxy method of physician's assessment of sexual maturation, using pubertal hormones in overweight African-American (AA) children. Cross-sectional data from 196 children (113 girls, 83 boys) aged 9-11 years, who were 'overweight' (>85th and 95th percentile; n = 153) were used. Children assessed their breast or genital and pubic hair development using standardized Tanner drawings representing different stages of sexual maturity. SRT data were compared to pubertal stage assessed by measuring fasting serum concentrations of luteinizing hormone (LH) in boys, and LH and estradiol (E2) in girls, which were used to stage children into pubertal stages 1-5. SRT stages of genital and pubic hair assessments in boys, and breast and pubic hair assessments in girls, yielded 15-20% concordance (kappa statistic = 0.02-0.12) compared to their hormone-derived pubertal stages. Among overweight AA 9-11 year-old children, self-assessment of Tanner staging did not accurately assess their pubertal development when compared to a hormone-derived pubertal assessment method.

    Patients with end-stage renal disease are affected by cardiovascular complications, including disturbances of the heart intraventricular conduction. Body surface potential mapping is a non-invasive electrocardiographic detection method of initial disturbances in heart activation propagation. A goal of the study was to analyze the effects of single hemodialysis (HD) session on ventricular activation time (VAT) maps obtained from hemodialyzed children. The study group consisted of 13 hemodialyzed children (age: 6-18 years). The control group is composed of 26 healthy subjects. In each HD patient, 12-lead electrocardiogram and echocardiography examinations were performed. Isochrone heart maps, reflecting body surface distribution of VAT isolines, were recorded from an 87-electrode HPM-7100 system for body surface potential mapping, before (group B) and after HD session (group A). The distribution of isochrones and VAT values, as recorded in the HD patients, differed significantly from the reference VAT map for controls. The highest VAT maximal value was noted in group B (Me: 110 vs. 62 ms in the control group; P children with end-stage renal disease exhibited disturbances of intraventricular conduction within the left bundle branch block, undetectable on standard electrocardiogram. A single HD session resulted in VAT map improvement related to overall HD treatment duration. © 2014 International Society for Hemodialysis.

    2012-05-01

    Full Text Available Abstract Background This retrospective study compared the clinicopathological results among three groups divided by time sequence to evaluate the impact of introducing laparoscopic surgery on long-term oncological outcomes for right-sided colon cancer. Methods From April 1986 to December 2006, 200 patients who underwent elective surgery with stage II and III right-sided colon cancer were analyzed. The period for group I referred back to the time when laparoscopic approach had not yet been introduced. The period for group II was designated as the time when first laparoscopic approach for right colectomy was carried out until we overcame its learning curve. The period for group III was the period after overcoming this learning curve. Results When groups I and II, and groups II and III were compared, overall survival (OS did not differ significantly whereas disease-free survival (DFS in groups I and III were statistically higher than in group II (P = 0.042 and P = 0.050. In group III, laparoscopic surgery had a tendency to provide better long-term OS ( P = 0.2036 and DFS ( P = 0.2356 than open surgery. Also, the incidence of local recurrence in group III (2.6% was significantly lower than that in groups II (7.4% and I (12.1% ( P = 0.013. Conclusions Institutions should standardize their techniques and then provide fellowship training for newcomers of laparoscopic colon cancer surgery. This technique once mastered will become the gold standard approach to colon surgery as it is both safe and feasible considering the oncological and technical aspects.

  3. Efficacy of Adjuvant 5-Fluorouracil Therapy for Patients with EMAST-Positive Stage II/III Colorectal Cancer.

    Directory of Open Access Journals (Sweden)

    Yasushi Hamaya

    Full Text Available Elevated Microsatellite Alterations at Selected Tetranucleotide repeats (EMAST is a genetic signature found in up to 60% of colorectal cancers (CRCs that is caused by somatic dysfunction of the DNA mismatch repair (MMR protein hMSH3. We have previously shown in vitro that recognition of 5-fluorouracil (5-FU within DNA and subsequent cytotoxicity was most effective when both hMutSα (hMSH2-hMSH6 heterodimer and hMutSβ (hMSH2-hMSH3 heterodimer MMR complexes were present, compared to hMutSα > hMutSβ alone. We tested if patients with EMAST CRCs (hMutSβ defective had diminished response to adjuvant 5-FU chemotherapy, paralleling in vitro findings. We analyzed 230 patients with stage II/III sporadic colorectal cancers for which we had 5-FU treatment and survival data. Archival DNA was analyzed for EMAST (>2 of 5 markers mutated among UT5037, D8S321, D9S242, D20S82, D20S85 tetranucleotide loci. Kaplan-Meier survival curves were generated and multivariate analysis was used to determine contribution to risk. We identified 102 (44% EMAST cancers. Ninety-four patients (41% received adjuvant 5-FU chemotherapy, and median follow-up for all patients was 51 months. Patients with EMAST CRCs demonstrated improved survival with adjuvant 5FU to the same extent as patients with non-EMAST CRCs (P<0.05. We observed no difference in survival between patients with stage II/III EMAST and non-EMAST cancers (P = 0.36. There is improved survival for stage II/III CRC patients after adjuvant 5-FU-based chemotherapy regardless of EMAST status. The loss of contribution of hMSH3 for 5-FU cytotoxicity may not adversely affect patient outcome, contrasting patients whose tumors completely lack DNA MMR function (MSI-H.

    Purpose: Orchiectomy followed by infradiaphragmatic irradiation is the standard treatment for Stage I-II testicular seminoma in The Netherlands. Because body image and sexual functioning can be affected by treatment, a retrospective study was carried out to assess treatment outcome, body image, and changes in sexuality after orchiectomy and radiotherapy. Methods and Materials: The medical charts of 166 patients with Stage I-II testicular seminoma were reviewed. A questionnaire on body image and current sexual functioning regarding the frequency and quality of erections, sexual activity, significance of sex, and changes in sexuality was sent to 157 patients (at a mean of 51 months after treatment). Results: Seventy-eight percent (n=123, mean age 42 years) completed the questionnaire. During irradiation, almost half of patients experienced nausea and 19% nausea and vomiting. Only 3 patients had disease relapse. After treatment, about 20% reported less interest and pleasure in sex and less sexual activity. Interest in sex, erectile difficulties, and satisfaction with sexual life did not differ from age-matched healthy controls. At the time of the survey, 17% of patients had erectile difficulties, a figure that was significantly higher than before treatment, but which correlated also with age. Twenty percent expressed concerns about fertility, and 52% found their body had changed after treatment. Cancer treatment had negatively influenced sexual life in 32% of the patients. Conclusions: Orchiectomy with radiotherapy is an effective and well-tolerated treatment for Stage I-II testicular seminoma. Treatment-induced changes in body image and concerns about fertility were detected, but the sexual problems encountered did not seem to differ from those of healthy controls, although baseline data are lacking

Methods: A total of 54 patients were retrospectively reviewed, 35 patients underwent subradical hysterectomy and 19 patients received radical hysterectomy, both with simultaneous bilateral salpingo-oophorectomy and pelvic and paraaortic lymphadenectomy. Results: Comparing the surgical outcomes in subradical hysterectomy group vs radical hysterectomy group, there were no significant differences in operative time, estimated blood loss, and hospital stay. After surgery, 37.1% vs 36.8% patients received postoperative radiotherapy in the subradical hyster­ectomy group vs radical hysterectomy group, without statistically significant difference. As for postoperative complications, the early postoperative complication rate in patients who underwent subradical hysterectomy was 14.3%, significantly lower than that in patients submitted to radical hysterectomy (14.3% vs 42.1%, with P=0.043. However, there was no significant difference in late postoperative complication rate between the two surgical procedures. Regarding the clinical prognosis, patients receiving the subradical hysterectomy showed similar survival to their counterparts undergoing the radical procedures. The relapse rate was 5.71% vs 5.26%, respectively, without significant difference. There were no deaths in both surgical groups. Conclusion: For stage II endometrial carcinoma, subradical hysterectomy presented with less early postoperative complications and similar survival duration and recurrence

    Zohar, Sarah; Chevret, Sylvie

    2003-02-01

    We propose a new design for phase I (or phase II) dose-ranging clinical trials aiming at determining a dose of an experimental treatment to satisfy safety (respectively efficacy) requirements, at treating a sufficiently large number of patients to estimate the toxicity (respectively failure) probability of the dose level with a given reliability, and at stopping the trial early if it is likely that no dose is safe (respectively efficacious). A two-stage design was derived from the Continual Reassessment Method (CRM), with implementation of Bayesian criteria to generate stopping rules. A simulation study was conducted to compare the operating characteristics of the proposed two-stage design to those reached by the traditional CRM. Finally, two applications to real data sets are provided.

    Motor imagery (MI) has been used as a complementary therapeutic tool for motor recovery after central nervous system disease and peripheral injuries. However, it has never been used as a preventive tool. We investigated the use of MI in the rehabilitation of stage II shoulder impingement syndrome. For the first time, MI is used before surgery. Sixteen participants were randomly assigned to either a MI or control group. Shoulder functional assessment (Constant score), range of motion and pain were measured before and after intervention. Higher Constant score was observed in the MI than in the control group (p=0.04). Participants in the MI group further displayed greater movement amplitude (extension (pimpingement syndrome: Helps in alleviating pain Enhances shoulder mobility Motor imagery is a valuable technique that can be used as a preventive tool before the stage III of the impingement syndrome.

    In locally advanced primary transverse colon cancer, a tumor may cause perforation or invade adjacent organs. Extensive resection is the best choice of treatment, but such procedures must be weighed against the potential survival benefits. This study was performed to identify the clinicopathological features and treatment outcomes of such tumors. We retrospectively reviewed the database of the Colorectal Cancer Registry of Chang Gung Memorial Hospital between February 1995 and December 2005. Patients with colon cancer sited between the hepatic and splenic flexure that involved an adjacent organ without distant metastasis were defined as having locally advanced transverse colon cancer. A total of 827 patients who underwent surgery for transverse primary colon cancer were enrolled in the study. Stage II and stage III colon cancer were diagnosed in 548 patients. Thirty-two (5.8%) patients were diagnosed with locally advanced tumors. Multivariate analysis revealed that stage III, preoperative carcinoembryonic antigen ≥5 ng/mL, a tumor with perforation or obstruction, and the presence of a locally advanced tumor were significant prognostic factors for both overall and cancer-specific survival. Postoperative morbidity rates differed significantly between the locally advanced and non-locally advanced tumor groups (22.7% vs. 12.3%, P transverse colon tumors (P = 0.21). Surgical resection of locally advanced transverse colon tumors resulted in a higher morbidity and mortality than that of non-locally advanced tumors, but the benefit of extensive surgery in the case of locally advanced tumors cannot be underestimated. Furthermore, this benefit is more pronounced in the case of stage II tumors.

    The purpose of this randomized pilot study was to collect preliminary data regarding the feasibility and effects of early initiation of milk expression on the onset of lactogenesis stage II and milk volume in mothers of very low birth weight (VLBW) infants. Twenty women were randomized to initiate milk expression within 60 min (group 1) or 1 to 6 h (group 2) following delivery. Milk volume and timing of lactogenesis stage II was compared between groups using Wilcoxon's rank sum tests. Group 1 produced statistically significantly more milk than group 2 during the first 7 days (P=0.05) and at week 3 (P=0.01). Group 1 also demonstrated a significantly earlier lactogenesis stage II (P=0.03). Initiation of milk expression within 1 h following delivery increases milk volume and decreases time to lactogenesis stage II in mothers of VLBW infants.

    We report on the results of a phase II clinical trial of Panagen (tablet form of fragmented human DNA preparation) in breast cancer patients (placebo group n = 23, Panagen n = 57). Panagen was administered as an adjuvant leukoprotective agent in FAC and AC chemotherapy regimens. Pre-clinical studies clearly indicate that Panagen acts by activating dendritic cells and induces the development of adaptive anticancer immune response. We analyzed 5-year disease-free survival of patients recruited into the trial. Five-year disease-free survival in the placebo group was 40 % (n = 15), compared with the Panagen arm - 53 % (n = 51). Among stage III patients, disease-free survival was 25 and 52 % for placebo (n = 8) and Panagen (n = 25) groups, respectively. Disease-free survival of patients with IIIB + C stage was as follows: placebo (n = 6)-17 % vs Panagen (n = 18)-50 %. Disease-free survival rate (17 %) of patients with IIIB + C stage breast cancer receiving standard of care therapy is within the global range. Patients who additionally received Panagen demonstrate a significantly improved disease-free survival rate of 50 %. This confirms anticancer activity of Panagen.

    Outcome of end-stage renal disease (ESRD) in children has considerably improved since the development of dialysis and kidney transplantation. This study was conducted to evaluate the management and outcome of ESRD children in a referral pediatric center in northwest Iran. A cross-sectional study of medical records of ESRD children (glomerular filtration rate less than 15 ml/min/1.73 m(2)) younger than 16 years who were admitted in Children's Hospital of Tabriz between October 1999 and October 2009 was performed. Ninety-four children with ESRD including 51 boys (54.3%) and 43 girls (45.7%) with a mean age of 7.9 ± 3.49 years were studied. Parents of nine patients (7.8%) refused treatment. Eighty patients underwent renal replacement therapy (RRT) and were followed for a mean period of 4.86 ± 2.77 years. Initial modality of RRT was hemodialysis in 81.25%, continuous ambulatory peritoneal dialysis in 16.25%, and preemptive kidney transplantation in 2.5%. Thirty-two patients (34%) underwent renal transplantation. The mean duration of staying on dialysis before transplantation was 12.4 ± 11 months. Twenty-nine of kidney donors (90.6%) were living unrelated donors. The 1-and 3-year graft survival rates were 81.2% and 68.8% and the 1- and 3-year patient survival rates were 96.9% and 93.8%, respectively. Thirty-one patients died (33%). The mortality of girls was significantly higher than boys (P=0.04). There was a significant negative correlation between age and mortality (P=0.01). Heart failure and infections were the most common cause of death. This study showed that ESRD children in our area have a poor outcome in comparison with developed countries.

    To quantify the impact of preradiotherapy 18F-fluoro-2-deoxyglucose positron-emission tomography (FDG-PET) on treatment strategy and radiotherapy planning for patients with Stage I/II Hodgkin disease included in a large prospective multicenter study. Conventional computed tomography and FDG-PET were performed just before the planned radiotherapy. The radiotherapy plan was first elaborated under blinded conditions for FDG-PET data. Then, the medical staff was asked to confirm or not confirm the treatment strategy and, if appropriate, to modify the radiotherapy plan based on additional information from FDG-PET. Between January 2004 and January 2006, 137 patients were included (124 were available for analysis) in 11 centers (108 adults, 16 children). All but 1 patient had received chemotherapy before inclusion. Prechemotherapy work-up included FDG-PET for 61 patients, and data were available for elaboration of the first radiotherapy plan. Based on preradiotherapy FDG-PET data, the radiotherapy was cancelled in 6 patients (4.8%), and treatment plan modifications occurred in 16 patients (12.9%): total dose (11 patients), CTV volume (5 patients), number of beam incidences (6 patients), and number of CTV (6 patients). The concordance between the treatment strategies with or without preradiotherapy FDG-PET was 82.3%. Concordance results were not significantly different when prechemotherapy PET-CT information was available. Preradiotherapy FDG-PET for treatment planning in Hodgkin lymphoma may lead to significant modification of the treatment strategy and the radiotherapy planning in patients with Stage I or II Hodgkin disease, even in those who have undergone FDG-PET as part of the prechemotherapy work-up.

    The end-stage renal disease (ESRD) in children has special features in terms of etiologies, therapeutic modalities and access to renal transplantation. In Tunisia, there are no data on the epidemiology of ESRD in children. The aim of our study was to describe epidemiology of ESRD among Tunisian children. This retrospective study was conducted in pediatric departments in Charles-Nicolle Hospital, Tunis and Hedi Chaker hospital, Sfax, during a period of 15 years (1st January 1998-31st December 2013). We included children who develop ESRD before the age of 15 years. In total, 166 patients were included. The median duration of follow-up was 48 months. We collected respectively 24 children (14.5%) aged less than 2 years, 24 children (14.5%) aged between 2 and 6 years and 118 children (71%) older than 6 years. The sex ratio was equal to 1.4. The mean incidence was 4.25 cases per million children. The main causes were represented by congenital anomalies of the kidneys and urinary tract (35.5%), hereditary renal disease (31.3%) and glomerular kidney disease (9.6%). All patients were treated in kidney transplant dialysis programs; the main mode of dialysis was represented by peritoneal dialysis, which represented the initial dialysis mode in 81% of cases. The transition to hemodialysis was noted in 43.4% cases. Thirty-eight patients (22.8%) were transplanted. The mortality rate was 27.1%. The leading cause of death was cardiovascular diseases (37.7%) and infections (22.2%). The creation of a national registry of kidney disease in Tunisia is necessary for a better knowledge of needs for dialysis and renal transplantation in children.

    There has been no study to evaluate the use of the Rome III criteria for diagnosis of constipation in the unselected young pediatric population. The aim of this study was to evaluate and compare the use of the Rome II and Rome III criteria for diagnosis of constipation in a group of unselected young Thai children. This cross-sectional study was conducted in 3010 healthy children aged 4 months-5 years who attended a well-baby clinic. Data concerning bowel habits and behavioral components of defecation of the children were obtained by interviewing the parents. Presence of a large fecal mass in the rectum of children with possible constipation was evaluated by abdominal palpation. Seventy-one children (2.4%) were found to have constipation, based on at least one of the two sets of criteria, at the time of interview. The prevalence of constipation as defined according to the Rome II and Rome III criteria for functional constipation (FC) was 1.9% and 1.6%, respectively. The majority of constipated children (47.9%) met the diagnostic criteria of both the Rome II and Rome III for FC, followed by the Rome II criteria for FC alone (32.4%) and the Rome III criteria for FC alone (18.3%). Twenty-one children (0.7%) whose parents reported defecation difficulties did not fulfill any diagnostic criteria for constipation. The prevalence of FC in young Thai children is low. For unselected young children, the Rome II criteria for FC are still appropriate for diagnosis of FC. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

    Full Text Available Background The aim of the present study was to determine whether serum vascular endothelial growth factor (VEGF can provide prognostic information independent of carcinoembryonic antigen levels in patients undergoing curative surgery. Methods Serum samples were collected from 158 patients with colorectal cancer and from 100 controls. Serum and tissue levels of VEGF were measured by enzyme-linked immunosorbent assay. Serum VEGF levels in colorectal cancer patients were compared with those in healthy controls, and we retrospectively assessed the association between serum VEGF levels and clinicopathologic findings and survival. Results VEGF expression was significantly higher in colorectal cancer tissue compared with nontumor tissue. Mean serum VEGF levels in patients were significantly higher than those in controls, and significantly higher in patients with large tumors, lymph node involvement, and distant metastases. Conclusion Elevated serum VEGF was significantly associated with poor survival, but was only an independent risk factor for poor survival in Stage II and/or III disease. Elevated serum VEGF is significantly associated with development of colorectal cancer, and lymph or distant invasive phenotypes and survival, especially in Stage II and III patients.

    Age estimation of young victims of natural and un-natural disasters remains a crucial and challenging task during the process of Disaster Victim Identification (DVI). The purpose of this study was to compare dental maturity using the Demirjian and Cameriere methods and to explore the relationship between dental age and cervical vertebral maturity (CVM) using the Hassel and Farman method for a group of New Zealand children. The study used lateral cephalometric and panoramic radiographs of 200 orthodontic patients aged 7-17 years. Dental age was calculated from mandibular tooth formation stages using the Demirjian and Cameriere methods by calculating the ratio of tooth length to apex width for these teeth. CVM was assessed using stages from Hassel and Farman. Reliability of maturity from reassessment of 20 radiographs showed good agreement for the three methods. Chronological and dental ages were compared using a mixed model. Descriptive statistics of dental ages by CVM stage were calculated. The results show that both dental methods were similar in assessing maturity. A disadvantage of using the Cameriere method was that all seven teeth reached maturity at 13.69 and 14.06 years in females and males respectively, compared to age 16 using the Dermijian method. Females reached CVM stages at earlier chronological and dental ages than males. Mean chronological age for CVM stages 2-5 is about 1 year earlier in females than males. The Demirjian and Cameriere methods of dental maturity and CVM are reliable and useful in assessing dental and skeletal maturity. Ideally in a DVI situation, both the methods of Demirjian and Cameriere, together with CVM, should be employed in the ageing of individuals suspected of being between 7 and 16 years.

    Classification systems developed in the field of posterior tibialis tendon dysfunction omit to include dynamic measurements. Since this may negatively affect the selection of the most appropriate treatment modality, studies on foot kinematics are highly recommended. Previous research characterised the foot kinematics in patients with posterior tibialis tendon dysfunction. However, none of the studies analysed foot segmental motion synchrony during stance phase, nor compared the kinematic behaviour of the foot in presence of different posterior tibialis tendon dysfunction stages. Therefore, we aimed at comparing foot segmental motion and coupling in patients with posterior tibialis tendon dysfunction grade 2 and 3 to those of asymptomatic subjects. Foot segmental motion of 11 patients suffering from posterior tibialis tendon dysfunction stage 2, 4 patients with posterior tibialis tendon dysfunction stage 3 and 15 asymptomatic subjects was objectively quantified with the Rizzoli foot model using an instrumented walkway and a 3D passive motion capture system. Dependent variables were the range of motion occurring at the different inter-segment angles during subphases of stance and swing phase as well as the cross-correlation coefficient between a number of segments. Significant differences in range of motion were predominantly found during the forefoot push off phase and swing phase. In general, both patient cohorts demonstrated a reduced range of motion compared to the control group. This hypomobility occurred predominantly in the rearfoot and midfoot (pfoot which should be considered in the decision making process since it may help explaining the success and failure of certain conservative and surgical interventions.

    2016-04-01

    Free muscle transfer for dynamic smile reanimation in facial paralysis is not always predictable with regard to cosmesis. Hospital stays range from 5 to 7 days. Prolonged operative times, longer hospital stays, and excessive cheek bulk are associated with free flap options. Lengthening temporalis myoplasty offers single-stage smile reanimation with theoretical advantages over free tissue transfer. From 2012 to 2014, 18 lengthening temporalis myoplasties were performed in 14 children for smile reconstruction. A retrospective chart review was completed for demographics, operative times, length of hospital stay, and perioperative complications. Fourteen consecutive patients with complete facial paralysis were included. Four patients underwent single-stage bilateral reconstruction, and 10 underwent unilateral procedures. Diagnoses included Möbius syndrome (n = 5), posterior cranial fossa tumors (n = 4), posttraumatic (n = 2), hemifacial microsomia (n = 1), and idiopathic (n = 2). Average patient age was 10.1 years. Average operative time was 410 minutes (499 minutes for bilateral lengthening temporalis myoplasty and 373 for unilateral lengthening temporalis myoplasty). Average length of stay was 3.3 days (4.75 days for bilateral lengthening temporalis myoplasty and 2.8 for unilateral lengthening temporalis myoplasty). Nine patients required minor revisions. Lengthening temporalis myoplasty is a safe alternative to free tissue transfer for dynamic smile reconstruction in children with facial paralysis. Limited donor-site morbidity, shorter operative times, and shorter hospital stays are some benefits over free flap options. However, revisions are required frequently secondary to tendon avulsions and adhesions. Therapeutic, IV.

    This paper very briefly describes criticality investigations for nuclear weapon dismantlement at the Pantex Plant. The investigations performed were for pit staging, and build on previous criticality calculations for single pits. The KENO and MCNP computer models were used for pit and container combinations. Scenarios were based on administrative limits and actual or potential physical conditions in the facilities. Essentially all of the pit configurations modeled were subcritical by a substantial amount. It was concluded that a critical configuration involving pit/container combinations is not credible

    Some uranium occurrences have been discovered as mineralized outcrops and soils at Jumbang II sector. The aim of this investigation is to find the mineralization characteristic, geometric and distribution and resources estimation. The investigation method is systematic topographic, geologic, and radiometric mapping and identification of uranium on the geological aspect. At Jumbang II have been identified four mineralization zones within total area 8.56 hectare. The mineralization zones consist of quartzite rock associations. The quartzite is characterized by the existence of some mineralized veins. The veins contain uraninite and secondary uranium mineral autunite and gummite, and it also contains monazite, tourmaline, biotite, feldspar, quartz, zircon, and some ore minerals. The ore minerals consist of molybdenite, pyrrhotite, magnetite, pyrite, hematite, chalcopyrite, galena, sphalerite and arsenopyrite. Uranium content of quartzite is about 28 ppm to 18,500 ppm U (A zone), 1,125.9 ppm U (B zone) and 515 ppm U (C and D zone). The lateral and vertical ore distributions are locally. The mineralization is veins type and is controlled by intersection WNW-ESE, NNE-EEW structure direction, which was vertical to sub vertical fractures. Resources potential within 80-m depth is 3,106.893 tons U metal

    Laser immunotherapy (LIT), a novel technique with a local intervention to induce systemic antitumor effects, was developed to treat metastatic cancers. The pre-clinical studies of LIT have shown its unique characteristics in generating a specific antitumor immunity in treating metastatic tumors in rats and mice. For late-stage, metastatic breast cancer patients, who were considered to be out of other available treatment options, we conducted a small Phase II clinical trial using LIT starting in 2009 in Lima, Peru. This Phase II study was closed in December of 2012, as acknowldged by the Ministry of Health (MOH) of Peur letter 438-2014-OGITT/INS dated March 5th, 2014. Ten patients were enrolled and received LIT in one or multiple 4-week treatment cycles. At the study closing date, four patients were alive and two of them remained cancer free. Here, following the successful conclusion of our Phase II study, we report the clinical effects of LIT on metastatic breast cancer patients. Specifically, we present the overall status of all the patients three years after the treatment and also the outcomes of two long-term surviving patients.

    This study aims to characterise the timing of referral to a paediatric nephrology unit of children who develop end-stage kidney disease (ESKD). This study also aims to determine whether late referral (LR) influences outcomes and to explore factors that may lead to LR. A retrospective case review of all incident patients with ESKD who received renal replacement therapy (RRT) at a single paediatric centre. Time between referral to a paediatric nephrologist and commencement of RRT, demographic and clinical data were collated. Estimated glomerular filtration rate (eGFR) at referral was calculated using height and creatinine. LR was defined as having an eGFR ≤ 30 mL/min/1.73 m(2) when first seen by a paediatric nephrologist. RRT was initiated for 74 patients Children referred before age 1 year (41%) had a more prolonged course before ESKD. Median (interquartile range) eGFR at referral of children > 1 year was 27.2 (9.0-52.0) mL/min/1.73 m(2) . Twenty-two (55%) of these children were referred late (LR) with an eGFR ≤ 30 mL/min/1.73 m(2) . LR patients were more likely to have glomerulonephritis or haemolytic uraemic syndrome and to live in a remote or outer regional area. LR patients had higher urea, lower haemoglobin and were more likely to receive haemodialysis via a vascular catheter. A significant proportion of children who develop ESKD are referred late to nephrology units with potentially preventable complications. Aetiology of renal disease and geographic isolation contribute to LR. © 2011 The Authors.

  14. High tumour cannabinoid CB1 receptor immunoreactivity negatively impacts disease-specific survival in stage II microsatellite stable colorectal cancer.

    Directory of Open Access Journals (Sweden)

    Sofia B Gustafsson

    Full Text Available BACKGROUND: There is good evidence in the literature that the cannabinoid system is disturbed in colorectal cancer. In the present study, we have investigated whether CB(1 receptor immunoreactive intensity (CB(1IR intensity is associated with disease severity and outcome. METHODOLOGY/PRINCIPAL FINDINGS: CB(1IR was assessed in formalin-fixed, paraffin-embedded specimens collected with a consecutive intent during primary tumour surgical resection from a series of cases diagnosed with colorectal cancer. Tumour centre (n = 483 and invasive front (n = 486 CB(1IR was scored from 0 (absent to 3 (intense staining and the data was analysed as a median split i.e. CB(1IR <2 and ≥2. In microsatellite stable, but not microsatellite instable tumours (as adjudged on the basis of immunohistochemical determination of four mismatch repair proteins, there was a significant positive association of the tumour grade with the CB(1IR intensity. The difference between the microsatellite stable and instable tumours for this association of CB(1IR was related to the CpG island methylation status of the cases. Cox proportional hazards regression analyses indicated a significant contribution of CB(1IR to disease-specific survival in the microsatellite stable tumours when adjusting for tumour stage. For the cases with stage II microsatellite stable tumours, there was a significant effect of both tumour centre and front CB(1IR upon disease specific survival. The 5 year probabilities of event-free survival were: 85±5 and 66±8%; tumour interior, 86±4% and 63±8% for the CB(1IR<2 and CB(1IR≥2 groups, respectively. CONCLUSIONS/SIGNIFICANCE: The level of CB(1 receptor expression in colorectal cancer is associated with the tumour grade in a manner dependent upon the degree of CpG hypermethylation. A high CB(1IR is indicative of a poorer prognosis in stage II microsatellite stable tumour patients.

    Two Web-based prognostic calculators (Adjuvant! and Numeracy) are widely used to individualize decisions regarding adjuvant therapy among patients with resected stage II and III colon cancer. However, these tools have not been directly compared. Hypothetical scenarios were formulated for the Numeracy calculator based on all potential combinations of age, lymph nodes status, tumor stage, and grade of tumor. These were then applied to three postsurgical therapy choices: observation, 5-fluorouracil (5-FU), or FOLFOX (5-FU, leucovorin, and oxaliplatin chemotherapy) to obtain the predicted 5-year disease-free survival (DFS) and overall survival (OS). Wilcoxon signed rank tests were used to compare the numerical predictions between the Adjuvant! and Numeracy calculators for each combination. A total of 192 hypothetical patient scenarios were obtained. For these patients, DFS and OS predictions from Adjuvant! were statistically significantly different than Numeracy (P <.05), except for four of 144 categories. While the estimated benefit in DFS and OS for 5-FU compared to surgery obtained from Adjuvant! and Numeracy were similar, the benefit in DFS and OS for FOLFOX over 5-FU, obtained from the Adjuvant! tool was slightly lower than that estimated from Numeracy. Among patients with resected stage II and III colon cancer, the DFS and OS estimates obtained from Numeracy and Adjuvant!, regarding the benefit of 5-FU over surgery, are similar, but the benefits of FOLFOX over 5-FU differ. Validation studies are needed to clarify the discrepancy and to assess the accuracy of these tools for predicting actual patient outcomes. Copyright 2010 Elsevier Inc. All rights reserved.

    Between 1976 and 1992, 32 patients aged 75 and older with stage I-II non-small cell lung cancer (NSCLC) were given definitive radiation therapy. These patients did not undergo surgery because of old age, poor cardiac/pulmonary condition, or refusal to give consent. The mean age was 79 years, and 11 patients were over 80 years old. The histologic type was squamous cell carcinoma in 25 patients and adenocarcinoma in 7. The clinical T and N stage was T1N0 in 4 patients, T2N0 in 9, and T2N0 in 19. The total dose of radiation therapy given to each patient exceeded 60 Gy using 10-MV X-rays. The treatment was completed in all 32 patients without treatment-related complications. The 2- and 5-year overall actuarial survival rates were 40% and 16%, respectively. Eleven intercurrent deaths occurred, including 7 patients who died of heart disease. The 2- and 5-year cause-specific survival rates were 57% and 36%, respectively. None of the patients developed severe pneumonitis requiring hospitalization. All but three patients received radiation therapy on an inpatient basis. The mean duration of the hospital stay for initial treatment was 56 days, and mean ratio to total survival period (mean 739 days) was 8%. Although many elderly patients have concurrent medical complications such as heart disease and chronic pulmonary disease, the present study showed that elderly patients with clinical stage I-II NSCLC can expert a realistic probability of long-term survival with definitive radiation therapy.

    The clinical records of 420 patients with diagnosis of breast cancer well documented by the pathological anatomy in clinical stage II, III and IV were reviewed. In each one of them has been done at least a bone scanning during the diagnosis. In 52 cases carried out sericeous dosages of CA 15-3 and in some cases it was necessary to administer Samarium-153 EDTMP as palliative therapy of bone pain. The presence of secondary gamma-graphic focuses was 0/84 cases (0%) in clinical stage II, 54/265 cases (20%) in III and 41/91 cases (45%) in IV. The one focus appeared in 6.7% of the cases. In 7 of the 52 cases that received sericeous dosages of CA 15-3 were detected secondary osseous lesions, and 5 of them presented a marker elevation. The bone scanning has shown in many cases the presence of getters focuses in singular places of skeleton, urinary excretory system or mammary tissue. The gamma rays from Sm-153 allowed us to get some appropriate basal views post-therapy of the secondary lesions. The results show that the great incidence of secondary lesions in the skeleton occurred in cases of stages III and IV unlike other countries. The serial repetition of the radioisotope scanning. The presence of one focus in the skeleton of a patient with a well-known neoplasia makes us to do a careful evaluation of the focus nature. The presence of tracer accumulation in the kidney, ureter and bladder allows us to infer the pathology of excretory system that is the first evidence of its presence in many cases.

    Purpose : Traditionally the patients with early stage non-Hodgkin's lymphoma of he head and neck was treated with radiotherapy. But the results were not satisfactory due to distant relapse. Although combined treatment with radiotherapy and chemotherapy was tried with some improved results and chemotherapy alone was also tried in recent years, the choice of treatment for the patients with early stage non-Hodgkin's lymphoma of the head and neck has not been defined. Therefore, in order to determine the optimum treatment method, we analysed retrospectively the outcomes of the patients with Ann Arbor stage I and II non-Hodgkin's lymphoma localized to the head and neck who were treated at Severance Hospital. Materials and Methods : 159 patients with stage I and II non-Hodgkin's lymphoma localized to the head and neck were treated at our hospital from January, 1979 to December, 1992. Of these patients, 114 patients whose primary sites were Waldeyer's ring or nodal region, and received prescribed radiation dose and/or more than 2 cycles of chemotherapy, were selected to analyze the outcomes according to the treatment methods (radiotherapy alone, chemotherapy alone, and combined treatment with radiotherapy and chemotherapy). Results : Five year overall actuarial survival of the patients whose primary site was Waldeyer's ring was 62.5%, and that of the patients whose primary site was nodal region was 53.8%. There was no statistically significant difference between survivals of both groups. Initial response rate to radiotherapy, chemotherapy, and combined treatment was 92%, 83%, 94% respectively, and 5 year relapse free survival was 49.9%, 52.4%, 58.5% respectively (statistically no significant). In the patients with stage I, 3 year relapse free survival of chemotherapy alone group was 75% and superior to other treatment groups. In the patients with stage II, combined treatment group revealed the best result with 60.1% of 3 year relapse free survival. The effect of

    The impact of chronic photoinhibition of photosystem II (PSII) on the productivity of plants remains unknown. The present study investigated the influences of persistent decline in the PSII yield on morphology and productivity of Arabidopsis plants that were exposed to lincomycin at two different developmental stages (seedling and rosette stage). The results indicated that, although retarded, the lincomycin treated plants were able to accomplish the entire growth period with only 50% of the maximum quantum yield of primary photochemistry (Fv/Fm) of the control plants. The decline in quantum yield limited the electron transport rate (ETR). The impact of lincomycin on NPQ was not significant in seedlings, but was pronounced in mature plants. The treated plants produced an above ground biomass of 50% compared to control plants. Moreover, a linear relationship was found between the above ground biomass and total rosette leaf area, and the slope was decreased due to photoinhibition. The starch accumulation was highly inhibited by lincomycin treatment. Lincomycin induced a significant decrease in seed yield with plants treated from the rosette state showing higher yield than those treated from the seedling stage. Our data suggest that the sustained decline of PSII efficiency decreases plant productivity by constraining the ETR, leaf development and starch production. Copyright © 2017 Elsevier GmbH.

    A predator-prey model with a stage structure for the predator, which improves the assumption that each individual predator has the same ability to capture prey, is proposed by Wang et al. [Wang W, Mulone G, Salemi F, Salone V. Permanence and stability of a stage-structured predator-prey model. J Math Anal Appl 2001;262:499-528]. It is assumed that immature individuals and mature individuals of the predator are divided by a fixed age and that immature predators do not have the ability to attack prey. We do economic management behavior for Wang model [Wang et al., 2001] by continuous harvesting on predator and impulsive stocking on prey. Then, a delayed stage-structured Holling type II predator-prey model with impulsive stocking prey and continuous harvesting predator is established. It is also assumed that the predating products of the predator is only to increase its bearing ability. We obtain the sufficient conditions of the global attractivity of predator-extinction boundary periodic solution and the permanence of the system. Our results show that the behavior of impulsive stocking prey plays an important role for the permanence of the system, and provide tactical basis for the biological resource management. Further, the numerical analysis is also inserted to illuminate the dynamics of the system.

    Combining {sup 18}F-FDG PET with whole-body MR for paediatric cancer staging is practically feasible if imaging protocols can be streamlined. We compared {sup 18}F-FDG PET/STIR with accelerated {sup 18}F-FDG PET/FSPGR for whole-body tumour imaging in children and young adults. Thirty-three children and young adults (17.5 ± 5.5 years, range 10-30) with malignant lymphoma or sarcoma underwent a {sup 18}F-FDG PET staging examination, followed by ferumoxytol-enhanced STIR and FSPGR whole-body MR. {sup 18}F-FDG PET scans were fused with MR data and the number and location of tumours on each integrated examination were determined. Histopathology and follow-up imaging served as standard of reference. The agreement of each MR sequence with the reference and whole-body imaging times were compared using Cohen's kappa coefficient and Student's t-test, respectively. Comparing {sup 18}F-FDG PET/FSPGR to {sup 18}F-FDG PET/STIR, sensitivities were 99.3 % for both, specificities were statistically equivalent, 99.8 versus 99.9 %, and the agreement with the reference based on Cohen's kappa coefficient was also statistically equivalent, 0.989 versus 0.992. However, the total scan-time for accelerated FSPGR of 19.8 ± 5.3 minutes was significantly shorter compared to 29.0 ± 7.6 minutes for STIR (p = 0.001). F-FDG PET/FSPGR demonstrated equivalent sensitivities and specificities for cancer staging compared to {sup 18}F-FDG PET/STIR, but could be acquired with shorter acquisition time. (orig.)

    There is controversy about the consequences of physical exercise on human sleeping behaviors. Evidence suggests that voluntary physical exercise affects brain structures and functions. However, there are inconsistent data regarding the effects of exercise on sleep architecture and sleep continuity, especially the amounts of slow wave sleep (SWS) and rapid eye movement (REM) sleep. The aim of the present study was to investigate the effects of moderate and high intense physical exercise on vigilance state and sleep patterns in school-aged children. Eleven healthy children (12.6+/-0.8 years old) were recruited for this polysomnographic study and underwent two exercise sessions. The two exercise sessions on a bicycle ergometer were performed 3-4h prior to bedtime, lasted 30min and varied in intensity. The moderate-intensity exercise was at 65-70% of maximal heart rate (HR(max)) while the high-intensity exercise was at 85-90% HR(max) to exhaustion. Polysomnographic and physiological measurements, including oximetry, were made on three nights in random order and separated by 1 week. Vigilance tests were carried out before and after the three sleep periods. Only high-intensity exercise resulted in a significantly elevated SWS proportion and less sleep in stage 2 as well as a higher sleep efficiency and shorter sleep onset latency. No significant effects on REM sleep were found. The results suggest that exercise intensity is responsible for the effects on stage 2 sleep and SWS in children and support the hypothesis of homeostatic sleep regulation.

    Auditory system abnormalities commonly occur in patients with chronic renal disease and end-stage renal disease undergoing hemodialysis. The aim of this study was to determine the relationship between cochlear sensitivity and hemodialysis in dialytic and non-dialytic chronic kidney disease patients. The study included children aged 6-18 years that were divided into 3 groups: 36 non-dialytic patients with chronic kidney disease, 16 end-stage renal disease patients undergoing hemodialysis, and 30 healthy controls. Blood urea nitrogen, serum cystatin C levels, duration of chronic kidney disease, and the duration of hemodialysis were compared between the chronic kidney disease patients and end-stage renal disease patients undergoing hemodialysis. Hearing health was measured via tympanometry, pure-tone audiometry and distortion product otoacoustic emissions testing. Distortion product otoacoustic emission amplitudes and signal-to-noise ratios were significantly lower at all frequencies tested in the non-dialytic and dialytic groups than in the control group (pchronic renal disease-both dialytic and non-dialytic-should be monitored to prevent any further deterioration by avoiding potential ototoxic agents, even if their hearing thresholds are within normal limits.

    The lifespan and outcome of end stage renal disease (ESRD) children have dramatically improved since the development of continuous ambulatory peritoneal dialysis (CAPD), it offers several advantages over hemodialysis. Percutaneous placement of CAPD catheters in children is minimally invasive, reliable, safe and cost-effective method. Percutaneous method of CAPD catheter insertion can be used in children to avoid the complications of general anesthesia and surgery. This study was done to evaluate the efficacy of CAPD in children, to find out the complication profile of CAPD & to compare the advantages of surgical versus percutaneously placed CAPD catheters in children. This prospective longitudinal comparative study was carried out in the department of Pediatric Nephrology, Dhaka Medical College Hospital (DMCH), Bangladesh from July 2011 to June 2014. A total of 8 children with ESRD were included (Age 5-14 year, M: F=1: 1). All underwent CAPD, Group I = surgically placed CAPD catheter (N=5), Group II = percutaneously placed CAPD catheter (N=3). Average duration of CAPD in Group I and Group II were 31.6 vs. 9 (months) with a total of 158 vs. 27 patient months of CAPD respectively. The rate of complications of the 2 groups and their outcome were compared. Common complications being observed were peritonitis 1 episode per 12.1 vs. 1.8 patient months (pchildren (pchildren, but percutaneous method of catheter insertion is associated with higher rate of complications. Placement of catheter by surgical method with elective omentectomy will reduce catheter related complications. Early detection of peritonitis and prompt therapy is essential for a favourable outcome.

    The general aim was to obtain piloting data for a series of experiments about the prevalence of communication impairment in preschool children in Greece. At this screening stage of the overall project, teacher perceptions of communication impairment in 57 kindergartens servicing 1113 children were examined via a questionnaire distributed in the urban region of Patras. The specific research goals were (1) to screen for specific categories of communication impairment such as articulation/phonology, receptive language, expressive language and pragmatics, hearing, stuttering, and voice, as they appear in the mainstreamed kindergarten population and (2) to offer comparative information on sex differences in communication impairment(s). The information was gathered by administration of a Greek-adapted version of the Communication Checklist for Pre-school Teachers, which was administered three times to obtain validity and reliability measures. The results were analysed separately for two studies (original and follow-up) and indicated teacher estimates of 14.4-18.7% for communication impairment in kindergarten children of the Patras region. Prevalence was higher for boys than for girls. Analysis of specific communication areas revealed that prevalence varies according to gender and category of communicative impairment. The limitations and follow-up needs of this study are discussed.

    This study was designed to investigate the impact of pediatric end-stage renal disease (ESRD) on parents, based on the PedsQL™ Family Impact Module (FIM), and the relationship to the quality of life (QOL) of pediatric ESRD patients measured by PedsQL TM 3.0 ESRD module. We performed a cross-sectional study using Korean translations of the PedsQL TM FIM and the PedsQL TM 3.0 ESRD module. In all, 79 patients were enrolled, including 47 children receiving dialysis and 32 children who underwent renal transplant. FIM scores, analyzed for every category according to treatment modality, were significantly lower in hemodialysis (HD) than in peritoneal dialysis (PD) or renal transplant patients. Mother's age, duration since diagnosis of ESRD and the existence of comorbidity were variables to have significant effects on FIM scores. The correlation between total FIM and QOL scores of pediatric patients were significant, in both parent-proxy and child-self report. The PedsQL™ FIM appears to be a useful tool for the assessment of family impact on children with ESRD. Further prospective studies focused on the QOL of parents and caregivers should be performed with the goal of improving clinical outcomes for pediatric ESRD patients.

    Growth retardation in children with chronic kidney disease (CKD) is multifactorial that include inadequate protein and calorie intake, persistent metabolic acidosis, calcitriol deficiency, renal osteodystrophy, drug toxicity, uremic toxins and growth factor abnormalities such as insulin- like growth factor (IGF) and IGF binding proteins. In this study, we compare the IGF-1 levels in normal and growth retarded CKD children. Serum IGF-1 levels were determined in 22 children with end-stage renal disease, 26 children, with CKD at different stages, 23 children with normal height and weight for age, and 23 children with constitutionally short stature. Mean serum levels of IGF-1 were 209+- ng/m1 in the ESRD group (group1), 159+-163 ng/m1 in the CKD group (group2), 420+-182 ng/ml in normal children (group3), and 360+-183 ng/ml in children with constitutional short stature (group4). The differences in the levels of IGF-1 in groups 1 and 2 were statistically significant when compared to groups 3 and 4(p<0.0001 and p< 0.02, respectively), while the levels of IGF-1 were not statistically different between groups 1 and 2. No correlation was found between IGF-1levels and glomerular filtrations are height or weight in groups 1 and 2. In conclusion, serum levels of IGF-1 in children with CKD are significantly lower than healthy children. (author)

    We previously found that administration of an interleukin 2/diphtheria toxin conjugate (DAB/IL2; Denileukin Diftitox; ONTAK) to stage IV melanoma patients depleted CD4 + CD25 HI Foxp3 + regulatory T cells and expanded melanoma-specific CD8 + T cells. The goal of this study was to assess the clinical efficacy of DAB/IL2 in an expanded cohort of stage IV melanoma patients. In a single-center, phase II trial, DAB/IL2 (12 μg/kg; 4 daily doses; 21 day cycles) was administered to 60 unresectable stage IV melanoma patients and response rates were assessed using a combination of 2-[ 18 F]-fluoro-2-deoxy-glucose (FDG)-positron emission tomography (PET) and computed tomography (CT) imaging. After DAB/IL2 administration, 16.7% of the 60 patients had partial responses, 5% stable disease and 15% mixed responses. Importantly, 45.5% of the chemo/immuno-naïve sub-population (11/60 patients) experienced partial responses. One year survival was markedly higher in partial responders (80 ± 11.9%) relative to patients with progressive disease (23.7 ± 6.5%; p value < 0.001) and 40 ± 6.2% of the total DAB/IL2-treated population were alive at 1 year. These data support the development of multi-center, randomized trials of DAB/IL2 as a monotherapy and in combination with other immunotherapeutic agents for the treatment of stage IV melanoma. http://www.clinicaltrials.gov/ct2/show/NCT00299689

    Prognostic markers that identify patients with stage II colon cancers who are at the risk of recurrence are essential to personalize therapy. We evaluated the potential of GIV/Girdin as a predictor of recurrence risk in such patients. Expression of full-length GIV was evaluated by IHC using a newly developed mAb together with a mismatch repair (MMR)-specific antibody panel in three stage II colon cancer patient cohorts, that is, a training (n = 192), test (n = 317), and validation (n = 181) cohort, with clinical follow-up data. Recurrence risk stratification models were established in the training cohort of T3, proficient MMR (pMMR) patients without chemotherapy and subsequently validated. For T3 pMMR tumors, GIV expression and the presence of lymphovascular invasion (LVI) were the only factors predicting recurrence in both training (GIV: HR, 2.78, P = 0.013; LVI: HR, 2.54, P = 0.025) and combined test and validation (pooled) cohorts (GIV: HR, 1.85, P = 0.019; LVI: HR, 2.52, P = 0.0004). A risk model based on GIV expression and LVI status classified patients into high- or low-risk groups; 3-year recurrence-free survival was significantly lower in the high-risk versus low-risk group across all cohorts [Training: 52.3% vs. 84.8%; HR, 3.74, 95% confidence interval (CI), 1.50-9.32; Test: 85.9% vs. 97.9%, HR, 7.83, 95% CI, 1.03-59.54; validation: 59.4% vs. 84.4%, HR, 3.71, 95% CI, 1.24-11.12]. GIV expression status predicts recurrence risk in patients with T3 pMMR stage II colon cancer. A risk model combining GIV expression and LVI status information further enhances prediction of recurrence. Further validation studies are warranted before GIV status can be routinely included in patient management algorithms.

    Full Text Available BACKGROUND Fluorouracil (5-FU based chemoradiotherapy represents the standard treatment option for the preoperative treatment of advanced rectal cancer. Capecitabine is an oral precursor of 5-FU with the advantage of delivering the chemotherapy in an outpatient setup. NSABP R-04 & a German phase 3 trial by Hofheinz et al showed that Capecitabine was equivalent to 5-FU. The primary objective of this study was to evaluate pathological response (PR, clinical & surgical outcomes of stage II & III patients treated with chemoradiation with Capecitabine. The secondary objective was to evaluate toxicity and compliance to treatment. MATERIALS AND METHODS This single arm prospective study included 35 patients with stages II & III adenocarcinoma of rectum who after evaluation were treated with pelvic radiotherapy and concurrent Capecitabine. Toxicities were graded using RTOG scoring criteria. Clinical response was assessed after EBRT completion, and patients were referred for surgery after 4-6 weeks. Pathologic response and completeness of resection were assessed from the histopathology report. RESULTS Growth located within 5 cm from anal verge was seen in 24 (68.5% patients and 6 were inoperable upfront. All patients completed the intended preoperative treatment and 88.6% did not have any toxicity related break in RT. Clinical response was seen in 80% of patients after Chemoradiation. Out of 35 treated 80% of them underwent surgery. APR was performed in 64.2% and 35.7% had LAR. Out of 6 upfront inoperable patients, 3 were converted to operable. Out of 23 APR cases, 7 were converted to anterior resection (30.4%, p=0.046. 96% of operated patients had an R0 resection, including all the 3 upfront inoperable patients. Minimal pathologic response was seen in 89.2% of patients and 7.14% had complete pathologic response. There were no Grade 4 or 5 toxicities. Only 2.9% had a Grade 3 event. 45.7% had maximum of Grade 1 events and 48.6% had maximum of Grade 2

    Cardiovascular morbidity and mortality are common in end stage renal disease (ESRD) patients. There is scarce data on carotid and bulb intima-media thickness (IMT-C and IMT-B) as an early marker of atherosclerosis and related factors in children on hemodialysis (HD) and peritoneal dialysis (PD). Since we did not have enough information about our patients, this study was carried on all ESRD children (hemodialysis and peritoneal dialysis) in a referral center. Data was collected from 16 ESRD children under 18 years with seven patients on PD and nine on HD. Lab tests and biochemical parameters including serum von Willebrand factor (vWF), homocystein, apo lipoprotein A, apo lipoprotein B and quantitative CRP were measured in fasting patients just before initiating dialysis. IMT-C and IMT-B were measured by gray scale ultrasound using 7.5 MHZ probe. The mean of age was 12.76+/-4.5 years. The mean duration of dialysis in HD and PD patients were not significantly different; 11.88+/-3.25 months and 10.14+/-2.4 months respectively. Mean of systolic blood pressure in HD group was significantly higher than PD group, 135.55+/-25.54 mmHg versus 121.42+/-12.14 mmHg, Phomocystein and IMT-C. However, we could not demonstrate any difference between IMT-B in case and control group. After adjusting for age, partial correlation showed significant correlation between IMT-C and following factors: N-PTH and serum alkaline phosphatase. Longitudinal studies with large size samples are needed to clarify the contributing factors with intima-media thickness in ESRD children.

    Studies have shown that it is necessary to create a database for dental maturity for every population and compare it to others. The present study is the first one for dental development in the Icelandic population the age range being 4-24 years. It will help in forensic dental age estimation and will also help dentists, physicians, anthropologists, archaeologists and other professionals who rely on developmental age assessment in children and adolescents. In this present retrospective cross-sectional study, dental maturity was determined in 1100 Icelandic children and adolescents from orthopantomograms (OPGs). The first 100 were used for a pilot study and the remaining 1000 for the main study. A total of 23 subjects were excluded. The sample consisted of 508 girls and 469 boys from the age of 4-24 years and a dental developmental scoring system was used as a standard for determination of dental maturity stages. A total of 200 OPGs were studied both on the left and right side and the remaining on the right side. Dental maturity was established for all teeth and both genders, when the sample permitted, from the beginning of crown formation to the root apex closure. The Cronbach's Alpha reliability test showed high reliability, R=0.982. Girls in Iceland reach dental maturity root completed (stage 10, Rc) at 17.81 years of age for the maxillary and at 18.47 years for the mandibular teeth. Boys reach dental maturity root completed (stage 10, Rc) at 18.00 years of age in the maxilla and 17.63 in the mandible. There was no significant difference between left and right side (r=0.95-1.00) and there was no gender difference, except in root formation in maxillary and mandibular canines where girls reached root completed earlier than boys. A reliable database has been established in Iceland for tooth development in the age range of 4-24 years, which is compatible with international studies. These results will help forensic odontologists and other professionals to estimate with

    There is a need to identify new markers to assess recurrence risk in early-stage colorectal cancer (CRC) patients. We explored the prognostic impact of ether-a-gò-gò-related gene 1 channels and some hypoxia markers, in patients with nonmetastatic (stage I, II, and III) CRC. The expression of hERG1, vascular endothelial growth factor A (VEGF-A), glucose transporter 1, carbonic anhydrase IX (CA-IX), epidermal growth factor receptor (EGF-R), and p53 was tested by immunohistochemistry in 135 patients. The median follow-up was 35 months. Clinicopathologic parameters and overall survival were evaluated. hERG1 displayed a statistically significant association with Glut-1, VEGF-A, CA-IX, and EGF-R; p53 with VEGF-A and CA-IX; Glut-1 with the age of the patients; and EGF-R with TNM and mucin content. TNM and CA-IX were prognostic factors at the univariate analysis; TNM, hERG1, and Glut-1, at the multivariate analysis. Risk scores calculated from the final multivariate model allowed to stratify patients into four different risk groups: A) stage I-II, Glut-1 positivity, any hERG1; B) stage I-II, Glut-1 and hERG1 negativity; C) stage I-II, Glut-1 negativity, hERG1 positivity; D) stage III, any Glut-1 and any hERG1. hERG1 positivity with Glut-1 negativity identifies a patient group with poor prognosis within stage I-II CRC. The possibility that these patients might benefit from adjuvant therapy, independently from the TNM stage, is discussed. More robust prognostic and predictive markers, supplementing standard clinical and pathologic staging, are needed for node-negative patients.

    Full Text Available Thrombocytosis portends adverse prognostic significance in many types of cancers including ovarian and lung carcinoma. In this study, we determined the prevalence and prognostic significance of thrombocytosis (defined as platelet count in excess of 400 × 103/μl in patients with colorectal cancer. We performed a retrospective analysis of 310 consecutive patients diagnosed at our Institution between 2004 and 2013. The patients (48.7% male and 51.3% female had a mean age of 69.9 years (+/- 12.7 years at diagnosis. Thrombocytosis was found in a total of 25 patients, with a higher incidence in those with stage III and IV disease (14.4% of patients. Although the mean platelet count increased with the depth of tumor invasion (pT, its values remained within normal limits in the whole patient cohort. No patient with stage I cancer (n=57 had elevated platelet count at diagnosis. By contrast, five of the 78 patients (6.4% with stage II cancer showed thrombocytosis, and four of these patients showed early recurrence and/or metastatic disease, resulting in shortened survival (they died within one year after surgery. The incidence of thrombocytosis increased to 12.2% and 20.6%, respectively, in patients with stage III and IV disease. The overall survival rate of patients with thrombocytosis was lower than those without thrombocytosis in the stage II and III disease groups, but this difference disappeared in patients with stage IV cancer who did poorly regardless of their platelet count. We concluded that thrombocytosis at diagnosis indicates adverse clinical outcome in colorectal cancer patients with stage II or III disease. This observation is especially intriguing in stage II patients because the clinical management of these patients is controversial. If our data are confirmed in larger studies, stage II colon cancer patients with thrombocytosis may be considered for adjuvant chemotherapy.

    Full Text Available Breast cancer is the most frequently occurring disease among women worldwide. The early stage of breast cancer identification is the key challenge in cancer control and prevention procedures. Although gene expression profiling helps to understand the molecular mechanism of diseases or disorder in the living system, gene expression pattern alone is not sufficient to predict the exact mechanisms. Current proteomics tools hold great application for analysis of cancerous conditions. Hence, the generation of differential protein expression profiles has been optimized for breast cancer and normal tissue samples in our organization. Normal and tumor tissues were collected from 20 people from a local hospital. Proteins from the diseased and normal tissues have been investigated by 2D gel electrophoresis and MALDI-TOF-MS. The peptide mass fingerprint data were fed into various public domains like Mascot, MS-Fit, and Pept-ident against Swiss-Prot protein database and the proteins of interest were identified. Some of the differentially expressed proteins identified were human annexin, glutathione S-transferase, vimentin, enolase-1, dihydrolipoamide dehydrogenase, glutamate dehydrogenase, Cyclin A1, hormone sensitive lipase, beta catenin, and so forth. Many types of proteins were identified as fundamental steps for developing molecular markers for diagnosis of human breast cancer as well as making a new proteomic database for future research.

    To investigate the nutritional status of children on maintenance hemodialysis due to stage 5 chronic kidney disease (CKD) and the clinical significance of nutritional assessment indices. A total of 21 children on maintenance hemodialysis due to stage 5 CKD were grouped according to body mass index. The nutritional status was assessed based on anthropometric parameters, biochemical parameters, inflammatory factors, residual renal function, indices of dialysis adequacy, and resting energy expenditure. Related indices were compared between the children with malnutrition and those with normal nutritional status. Of the 21 children, 10 had malnutrition and 11 had normal nutritional status. There were significant differences between the two groups in anthropometric parameters, levels of leptin, insulin-like growth factor-1, interleukin-1, interleukin-6, and tumor necrosis factor-α, and mean 24-hour residual urine volume (Pnutritional status of children with stage 5 CKD on maintenance hemodialysis. Further studies are needed to investigate the value of the measurement of resting energy expenditure in the evaluation and monitoring of nutritional status in children with stage 5 CKD on maintenance hemodialysis.

    Full Text Available Background. As to severity of the course, the incidence of complications and mortality rate, ulcerative colitis hold a position within the top of the gastrointestinal system diseases in children. Goal of research — to study peculiarities of the course of ulcerative colitis at the present stage. Materials and methods. The retrospective analysis was conducted of 184 clinical records of the children, who were on examination and treatment at the Department of the diseases of gastrointestinal system of the State Institution “Institute of Pediatrics, Obstetrics and Gynecology of the National Academy of Medical Sciences of Ukraine” between 2004 and 2014. Results and discussion. Ulcerative colitis is common in the children of all ages, among which the preschool children and teenagers are at greater risk than others. The risk factors include both the antenatal and the postnatal ones: gestational toxicosis and miscarriage threat, weight deficit at birth, artificial feeding, intestinal infections. Ulcerative colitis is characterized by chronic relapse, slow progression of the disease, and the typical clinical symptoms are: diarrhea, hemorrhagic colitis, abdominal pain syndrome, toxic syndrome, late physical development. In terms of localization, the inflammation process most often affects the entire large bowel (59.6 %, left-sided colitis (28.5 %, and proctosigmoiditis (accounts for 11.9 % are less common. The informative criteria of ulcerative colitis activity are the Pediatric Ulcerative Colitis Activity Index (PUCAI, fecal calprotectin level, a number of complete blood count values (hemoglobin, leucocytes, platelets, erythrocyte sedimentation rate and biochemical studies (C-reactive protein, alpha-2 globulins. The modern combined baseline therapy is efficient in 22 % of patients suffering from total colitis, in 42–58 % — from left-sided colitis according to the follow-up study results.

    Intracavitary Californium-252 combined with whole-pelvis photon radiotherapy was tested as the sole form of treatment for 22 patients with Stage IB carcinoma of the cervix. Californium-252 (Cf) is a fast neutron-emitting radioisotope currently being tested in trials of neutron brachytherapy (NT). The outcomes of the treated group of patients were traced for local tumor control, survival, patterns of failure, and complications. The Cf intracavitary therapy combined with whole-pelvis photon radiotherapy resulted in 95% 2-year and 91% 5-year actuarial survival. There were 9% Grade II-III complications by the Stockholm scale and 4% local failures. These results were obtained in an early clinical trial with a group of largely poor-risk patients with tumors of mean diameter of 4.3 cm.

    In this paper, we develop and study a stochastic predator-prey model with stage structure for predator and Holling type II functional response. First of all, by constructing a suitable stochastic Lyapunov function, we establish sufficient conditions for the existence and uniqueness of an ergodic stationary distribution of the positive solutions to the model. Then, we obtain sufficient conditions for extinction of the predator populations in two cases, that is, the first case is that the prey population survival and the predator populations extinction; the second case is that all the prey and predator populations extinction. The existence of a stationary distribution implies stochastic weak stability. Numerical simulations are carried out to demonstrate the analytical results.

    To evaluate the cephalometric changes in skeletal, dentoalveolar and soft tissue variables induced by Clark's Twin Block (CTB) in Class II, Division 1 malocclusion patients and to compare these changes in different cervical vertebral maturation stages. Pre- and post-treatment/observation lateral cephalograms of 53 Class II, Division 1 malocclusion patients and 60 controls were compared to evaluate skeletal, dentoalveolar and soft tissue changes. Skeletal maturity was assessed according to cervical vertebral maturation stages. Pre- and post-treatment/observation mean changes and differences (T2-T1) were compared by means of Wilcoxon sign rank and Mann-Whitney U-tests, respectively. Intergroup comparisons between different cervical stages were performed by means of Kruskal-Wallis test and Mann-Whitney U-test (p ≤ 0.05) . When compared with controls, there was a significant reduction in ANB angle (p cervical stages (p cervical stages (p cervical stages, significant differences were found for SNA, SNB and UI-SN angles and overjet. . The Twin-Block along with the normal craniofacial growth improves facial esthetics in Class II, Division 1 malocclusion by changes in underlying skeletal and dentoalveolar structures.

    The University of Minnesota Grid-ICES was divided into four identifiable programs in order to study the feasibility of each of the parts of the ICES independently. The total program involves cogeneration, fuel conversion, fuel substitution, and energy conservation by system change. This Phase II report substantiates the theory that the Basic Grid ICES is not only energy-effective, but it will become cost effective as unit operating costs adjust to supply and demand in the 1980's. The Basic Program involves the cogeneration of steam and electricity. The University of Minnesota has been following an orderly process of converting its Central Heating Plant from gas-oil to 100% coal since 1973. The first step in the transition is complete. The University is presently 100% on coal, and will begin the second step, the test burning of low Btu Western coal during the spring, summer, and fall, and high Btu Eastern coal during the high thermal winter period. The final step to 100% Western coal is planned to be completed by 1980. In conjunction with the final step a retired Northern States Power generating plant has been purchased and is in the process of being retrofitted for topping the existing plant steam output during the winter months. The Basic Plan of ICES involves the add-on work and expense of installing additional boiler capacity at Southeast Steam and non-condensing electric generating capability. This will permit the simultaneous generation of electricity and heat dependent upon the thermal requirements of the heating and cooling system in University buildings. This volume presents an overview of the Community and the ICES. (MCW)

    2011-05-01

    Full Text Available Abstract Background The presence of lymph node metastases remains the most reliable prognostic predictor and the gold indicator for adjuvant treatment in colon cancer (CC. In spite of a potentially curative resection, 20 to 30% of CC patients testing negative for lymph node metastases (i.e. pN0 will subsequently develop locoregional and/or systemic metastases within 5 years. The presence of occult nodal isolated tumor cells (ITCs and/or micrometastases (MMs at the time of resection predisposes CC patients to high risk for disease recurrence. These pN0micro+ patients harbouring occult micrometastases may benefit from adjuvant treatment. The purpose of the present study is to delineate the subset of pN0 patients with micrometastases (pN0micro+ and evaluate the benefits from adjuvant chemotherapy in pN0micro+ CC patients. Methods/design EnRoute+ is an open label, multicenter, randomized controlled clinical trial. All CC patients (age above 18 years without synchronous locoregional lymph node and/or systemic metastases (clinical stage I-II disease and operated upon with curative intent are eligible for inclusion. All resected specimens of patients are subject to an ex vivo sentinel lymph node mapping procedure (SLNM following curative resection. The investigation for micrometastases in pN0 patients is done by extended serial sectioning and immunohistochemistry for pan-cytokeratin in sentinel lymph nodes which are tumour negative upon standard pathological examination. Patients with ITC/MM-positive sentinel lymph nodes (pN0micro+ are randomized for adjuvant chemotherapy following the CAPOX treatment scheme or observation. The primary endpoint is 3-year disease free survival (DFS. Discussion The EnRoute+ study is designed to improve prognosis in high-risk stage I/II pN0 micro+ CC patients by reducing disease recurrence by adjuvant chemotherapy.

    Perinatal asphyxia with hypoxic ischemic encephalopathy (HIE) causes significant mortality and morbidity in developing countries. There is limited information about long term neurodevelopmental outcome of infants with neonatal encephalopathy. Term infants with the diagnosis of perinatal asphyxia were followed up in neurodevelopmental clinics of Manipal Teaching hospital, Nepal. Study design was prospective mixed longitudinal study. Prematurity, major congenital malformations, other intracranial pathology, birth weight <2500g and chromosomal abnormalities were excluded. After consent and enrollment their detailed perinatal history, Apgar score, resuscitation measures and outcome parameters were recorded on a predesigned proforma. Developmental assessment was done with Denver Developmental Screening Tool 2nd edition (DDST 2) at the age of 3months, 6months, 9months, 1year, 18months and 2years. Total 187 assessments done in the age group of 3months to 2years among HIE stage 2 patients. Impaired hearing and vision was noted in 5.3% while language delay was observed in 19.2% of infants. Abnormal tone and deep tendon reflexes were noted in 46.2% infants at 3months. Abnormal tone and reflexes were noted only in 18.8% and 9.4% respectively at the age of 2years. Overall, gross motor delay was noted in 55(29.4%) of patient, 34(18.2%) showed fine motor delay and 17.1% social delay. Seizures were persistent in 15.6% patients at 2years age. Infants affected with HIE have delay in all sectors of developmental milestones. Motor abnormalities are common and tend to improve with advancing age.

    Increased plasma Urotensin II (UII) levels have been found in adults with renal diseases. Studies in children are scarce. The objective of the study is to estimate plasma UII levels in subjects with chronic kidney disease (CKD) stages 3 to 5 and renal transplant recipients (RTR). In addition, the correlation of UII with anthropometric features and biochemical parameters was assessed. Fifty-four subjects, aged 3 to 20 years old, 23 with CKD, 13 with end-stage kidney disease (ESKD) undergoing hemodialysis (HD) and 18 RTR were enrolled. A detailed clinical evaluation was performed. Biochemical parameters of renal and liver function were measured. Plasma UII levels were measured in all patients and in 117 healthy controls, using a high sensitive enzyme immunoassay (EIA) kit. All data were analyzed using STATA™ (Version 10.1). Median UII and mean log-transformed UII levels were significantly higher in CKD and RTR patients compared to healthy subjects (p Children and adolescents with CKD, particularly those who are not on HD and RTR, have significantly higher levels of UII than healthy subjects. UII levels increase significantly at the end of the HD session. The presence of metabolic acidosis affects significantly plasma UII levels.

    The aim of the present study was to evaluate whether angiogenic parameters as assessed by transvaginal color Doppler ultrasound and by enhanced cervix ultrasound may predict prognostic factors of stage IB greater than 4 cm and II cervical cancer treated by radiochemotherapy. A total of 40 patients with histologically proven advanced stage invasive cervical cancer will be evaluated by color Doppler, contrast ultrasound, and MRI before radiotherapy, after the second chemotherapy cycle and prior to surgery. Subjective assessment of the amount of vessels within the tumor (scanty-moderate or abundant) and resistance index (RI) will be recorded for Doppler, enhancement and washout period will be studied after injection of SonoVue for contrast ultrasound. All patients will have radical hysterectomy and pelvic lymph node dissection. Comparison with MRI results will be done. The main parameter studied will be persistence of tumor cells in the analysis of the radical hysterectomy. We expected to correlate contrast parameters with persistent disease in order to confirm ultrasound parameters that will be useful to monitor radiochemotherapy and to predict therapeutic answer of such treatment.

    1983-01-01

    Between May, 1973 and December, 1980, 78 Stage I and II breast carcinomas in 76 patients were treated by biopsy and radiotherapy with curative intent. With a maximum follow-up of 10 years, a minimum of 2 1/2 years and a median follow-up of 3 1/2 years, a loco-regional control rate of 97% was obtained. Cosmetic results and treatment complications were studied. Patient characteristics, tumor size, excisional biopsy technique, axillary staging procedure and radiotherapy techniques were analyzed and all found to be important factors affecting cosmesis and complications. The most common complications included transient breast edema observed in 51% of patients, breast fibrosis (usually mild) seen in 23% of the population, axillary hematoma or seroma formation in 15%, mild arm edema in 14% and basilic vein thrombosis in 10% of patients. The causes of these and other less frequent complications are discussed. The overall cosmetic result was excellent in 78%, satisfactory in 18% and unsatisfactory in 4% of patients. Recommendations for improving cosmetic results and minimizing complications are made

    2011-08-01

    The objective of the study was to evaluate the prognostic effect of p53, PTEN, and concomitant p53 PTEN status on clinicopathologic features, recurrent disease, and disease-free survival (DFS) of 131 patients in FIGO stages I to II with epithelial ovarian cancer. The technique of tissue microarray and immunohistochemistry was used for the detection of positivity of the biologic markers p53 and PTEN. In the complete series, the 5-year DFS rate was 68%, and the overall survival rate was 71%. Positive staining for p53 and PTEN was detected in 25% and 22% of cases, respectively. Positivity of p53 was associated with tumor grade in the total series but not in the subgroup of serous tumors. In survival analysis, there was worse survival (P = 0.003) in the group of patients with p53-positive tumors compared with the group of patients with p53-negative tumors with DFS of 62% and 82%, respectively. Furthermore, DFS was 15% for the subgroup of patients with concomitant p53-positivity and PTEN-negativity of tumors compared with DFS of 62% for others in 1 group (p53+PTEN+, p53-PTEN+, p53-PTEN-) at 100 months. The difference was highly significant (P = 0.006). FIGO stage (odds ratio = 8.0) and p53 PTEN status (odds ratio = 0.6) were predictive factors for tumor recurrences in a logistic regression and prognostic factors with hazard ratios (HRs) of 4.0 and 0.6, respectively, in a multivariate Cox regression analysis. In a separate Cox regression analysis, FIGO stage (HR = 3.6) and p53 status (HR = 2.0) were prognostic factors for DFS. For serous tumors (n = 51) recurrent disease was associated with FIGO stage (P = 0.013), and p53 loss (P = 0.029) but not with FIGO grade (P = 0.169). p53 status divides ovarian carcinomas into 2 subgroups after prognosis, also in serous tumors. Presence of PTEN in p53-positive tumors seems to protect from bad prognosis and absence of PTEN seems to worsen prognosis in early stages.

    Full Text Available Background & Objectives: Hypertension is one of the most important and common health problems in societies. Hypertension is often asymptomatic and can be simply treated. Many of drugs are available for treatment of hypertension i ncluding d iuretics, beta blockers, blockers of calcium channel, angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists, alpha blockers and arterial dilators. This research was performed to evaluate the efficacy of some of these drugs on the hypertension. This may help to choose an appropriate medication for the treatment of stage 2 hypertension.   Methods: A total of 150 patients with hypertension who were not under antihypertensive treatment and didn’t have contraindications for using hydrochlorothiazide , enalapril and atenolol were randomly allocated into three groups. These groups received atenolol 50 mg daily, hydrochlorothiazide 50 mg daily and enalapril 5 mg twice daily, respectively . After three weeks blood pressure of patients was measured and results were analyzed using SPSS.   Results: Atenolol reduced systolic blood pressure (26.7±6.7 mm Hg 16.1%, diastolic blood pressure (10.3±1.2 mm Hg 10.4% and mean arterial blood pressure (16.1±6.4 mm Hg 13.1%. Enalapril reduced systolic blood pressure (30.6±8.8 mm Hg 17.4%, diastolic blood pressure (11.5±4.4 mm Hg 11.4% and mean arterial blood pressure (17.9±7.0 mm Hg 14.2%. Hydrochlorothiazide reduced systolic blood pressure (25.1±5.8 mm Hg 14.6%, diastolic blood pressure (9.2±2.3 mm Hg 9.3% and mean arterial blood pressure (14.5±6.4 mm Hg 11.8%.   Conclusion: Despite recommendations the use of hydrochlorothiazidein the treatment of hypertension, seems lower effect only use of this drug groups in comparison with other groups, and maybe add this category to other drugs and combined treatment is better than monotherapy with these groups .

    Transcobalamin II is a serum transport protein for vitamin B12. Small variations in TC-II affinity were recently linked to a high homocysteine level and increased frequency of neural tube defects. Complete absence of TC-II or total functional abnormality causes tissue vitamin B12 deficiency resulting in a severe disease with megaloblastic anemia and immunologic and intestinal abnormalities in the first months of life. This condition was described in hereditary autosomal-recessive form. Low serum TC-II without any symptoms or clinical significance was noted in relatives of affected homozygotes. To study 23 members of a four-generation family with hereditary vitamin B12 deficiency and neurologic disorders. Thorough neurologic, hematologic and family studies were supplemented by transcobalamin studies in 20 family members. Partial TC-II deficiency was found in 19 subjects. Apo TC-II (free TC-II unbound to vitamin B12) and total unsaturated B12 binding capacity were low in all tested individuals but one, and holo TC-II (TC-II bound by vitamin B12) was low in all family members. The presentation of the disease was chronic rather than acute. Early signs in children and young adults were dyslexia, decreased IQ, vertigo, plantar clonus and personality disorders. Interestingly, affected children and young adults had normal or slightly decreased serum vitamin B12 levels but were not anemic. Low serum B12 levels were measured in early adulthood. In mid-late adulthood megaloblastic anemia and subacute combined degeneration of the spinal cord were diagnosed. Treatment with B12 injections resulted in a significant improvement. The pedigree is compatible with an autosomal-dominant transmission. This family study suggests a genetic heterogeneity of TC-II deficiency. We report the first family with a hereditary transmitted condition of low serum TC-II (partial TC-II deficiency) associated with neurologic and mental manifestations in childhood. Partial TC-II deficiency may decrease

    Full Text Available Apical Membrane Antigen-1 (AMA1 is one of the leading blood stage malaria vaccine candidates. AMA1-C1/Alhydrogel consists of an equal mixture of recombinant AMA1 from FVO and 3D7 clones of P. falciparum, adsorbed onto Alhydrogel. A Phase 1 study in semi-immune adults in Mali showed that the vaccine was safe and immunogenic, with higher antibody responses in those who received the 80 microg dose. The aim of this study was to assess the safety and immunogenicity of this vaccine in young children in a malaria endemic area.This was a Phase 1 dose escalating study in 36 healthy children aged 2-3 years started in March 2006 in Donéguébougou, Mali. Eighteen children in the first cohort were randomized 2 ratio 1 to receive either 20 microg AMA1-C1/Alhydrogel or Haemophilus influenzae type b Hiberix vaccine. Two weeks later 18 children in the second cohort were randomized 2 ratio 1 to receive either 80 microg AMA1-C1/Alhydrogel or Haemophilus influenzae type b Hiberix vaccine. Vaccinations were administered on Days 0 and 28 and participants were examined on Days 1, 2, 3, 7, and 14 after vaccination and then about every two months. Results to Day 154 are reported in this manuscript.Of 36 volunteers enrolled, 33 received both vaccinations. There were 9 adverse events related to the vaccination in subjects who received AMA1-C1 vaccine and 7 in those who received Hiberix. All were mild to moderate. No vaccine-related serious or grade 3 adverse events were observed. There was no increase in adverse events with increasing dose of vaccine or number of immunizations. In subjects who received the test vaccine, antibodies to AMA1 increased on Day 14 and peaked at Day 42, with changes from baseline significantly different from subjects who received control vaccine.AMA-C1 vaccine is well tolerated and immunogenic in children in this endemic area although the antibody response was short lived.Clinicaltrials.gov NCT00341250.

    Introduction Maximal oxygen uptake (VO2 max) is associated with cardiovascular and metabolic risks but it is difficult to assess in obese children. The objective of this study was to develop an equation to estimate VO2 (mL/kg/min) and to check the % of tests that were maximal according to recommended criteria. Methods Stress tests were analyzed of 222 subjects (94 male and 128 female with a BMI above the 85 percentile for age and sex), and repeated 4 months later. Mean age was 9.4 ± 1.1 years and weighed 52.4 ± 13.3 kg. Body fat % (40.5 + 6.2) was determined by DXA (Hologic QDR 4500W). The protocol on the treadmill started with a warm up at 2.5 and 3 mph with a slope of 0% and 2%. The speed was kept at 3 mph for all the stages and the slope was increased 2% every 2 minutes. Statistical analysis (descriptive, t-test and ANOVAS 2×2×2) was done with SPSS 15.0. Results Only 35% of the tests were maximal. The equation calculates was Y = 2.6x + 22.3 (x = protocol stage). Data pre and post treatment were not statistically different Discussion Increments in VO2 were consistent despite subject diversity (sex, % body fat, physical fitness, treatment). Conclusion To be able to estimate VO2 at the different stages of the test without complex equipment or specialized staff, will facilitate the performance of stress tests on a daily basis.

    Feeding breastmilk to premature infants decreases morbidity but is often limited owing to an insufficient milk supply and delayed attainment of lactogenesis stage II. Early initiation of milk expression following delivery has been shown to increase milk production in mothers of very low-birth-weight (VLBW) infants. Although recommendations for milk expression in this population include initiation within 6 hours following delivery, little evidence exists to support these guidelines. This study compared milk volume and timing of lactogenesis stage II in mothers of VLBW infants who initiated milk expression within 6 hours following delivery versus those who initiated expression after 6 hours. Forty mothers of VLBW infants were grouped according to when they initiated milk expression following delivery. Group I began milk expression within 6 hours, and Group II began expression after 6 hours. Milk volume was measured daily for the first 7 days and on Days 21 and 42. Timing of lactogenesis stage II was determined through mothers' perceptions of sudden breast fullness. Group I produced more breastmilk during the initial expression session and on Days 6, 7, and 42. No difference in timing of lactogenesis stage II was observed. When mothers who began milk expression prior to 1 hour following delivery were removed from analysis, benefits of milk expression within 6 hours were no longer apparent. Initiation of milk expression within 6 hours following delivery may not improve lactation success in mothers of VLBW infants unless initiated within the first hour.

    The prognostic significance of chemokine receptors in stage I/II colon cancer is unclear. We assessed the prognostic value of chemokine receptor CXCR3 and CXCR4 in stage I/II colon cancer. 145 patients with stage I/II colon cancer who underwent curative surgery alone from 2000 to 2007 were investigated. Chemokine receptor expression was assessed by immunohistochemistry. The associations between CXCR3, CXCR4 and clinicopathological variables were analysed using the χ2 test, and the relationships between chemokine receptors and a 5-year disease-free survival were analysed by univariate and multivariate analyses. The high-expression rates of CXCR3 and CXCR4 were 17.9% (26/145) and 38.6% (56/145), respectively. There were no significant associations between the expressions of CXCR3, CXCR4 and clinicopathological factors including gender, age, tumour location, histological differentiation, pathological stage, lymphovascular invasion and pretreatment serum carcinoembryonic antigen (CEA). The 5-year disease-free survival was not significantly different between low-expression groups and high-expression groups of CXCR3 and CXCR4. Multivariate analysis revealed that serum CEA and a number of retrieved lymph nodes, rather than chemokine receptors, were independent prognosticators. CXCR3 and CXCR4 are not independent prognosticators for stage I/II colon cancer after curative surgery.

    Full Text Available Aims: (1 To map the extent of disease in women with stage I and II carcinoma cervix by multislice spiral computed tomography (CT, magnetic resonance imaging (MRI and sentinel nodes. (2 To assess accuracy of each modality individually and in conjunction with FIGO clinical staging. Design and Setting: Prospective, single-blind study. Departments of Obstetrics and Gynaecology, Radiodiagnosis, and Pathology, UCMS and GTBH and Division of Radiological Imaging and Bioinformatics, INMAS, Delhi. Material and Method: The study was conducted on 25 women with cervical cancer FIGO stage I and II. Each woman underwent clinical staging, multislice spiral CT and MRI which was compared to the gold-standard histopathology/cytology. The overall accuracy of each modality and improvement of clinical staging by CT/MRI were noted. Sentinel nodes were evaluated by intracervical Patent Blue V dye injection. Statistical Analysis: Sensitivity, specificity, positive and negative predictive values were calculated by 2Χ2 contingency tables. Results: The accuracy of staging by FIGO, CT and MRI was 68%, 52% and 80%, respectively. MRI and CT improved the overall accuracy of FIGO staging to 96% and 80%, respectively. Sentinel nodes were identified in 89% of patients with 91% accuracy. Conclusion: MRI emerges as the most valuable stand-alone modality improving accuracy of FIGO staging to 96%. Sentinel lymph-node evaluation appears promising in evaluating spread beyond cervix.

    Cardiovascular disease (CVD) is an important complication of chronic kidney disease (CKD) in children. However, it is not well known when and how cardiovascular alterations start. This cross-sectional, controlled study consisted of 25 patients and 28 healthy controls. 24-h ambulatory blood pressure monitoring, aortic pulse wave velocity (aPWV), carotid intima-media thickness (cIMT) and carotid distensibility (distensibility coefficient and β stiffness index), and echocardiography were assessed to evaluate CVD. Routine biochemical parameters, fibroblast growth factor-23 (FGF23) and high sensitive C- reactive protein were measured to determine cardiovascular risk factors. Hypertension was found in 12 patients (48 %). Patients had higher FGF23 levels and aPWV-standard deviation score (SDS) as compared to the controls (p = 0.003 and p = 0.002, respectively). Aortic PWV-SDS was predicted by increased daytime systolic blood pressure load (β = 0.512, p = 0.009, R 2  = 0.262). Neither cIMT nor distensibility differed between the groups; however, older age and high level of FGF23 were independent predictors of β stiffness index in patients (β = 0.507, p = 0.005, R 2  = 0.461 and β = 0.502, p = 0.005, R 2  = 0.461, respectively). As compared to controls, patients had worse left ventricular diastolic function [lower E/A ratio p = 0.006) and increased left atrial dimension (p children with stage-2 CKD. Good control of BP and decreasing the level of FGF23 may be useful to slow down the progression of cardiovascular complications.

    Full Text Available Growth failure is one of the most common and profound clinical manifestation of chronic kidney disease (CKD in infants, children and adolescents. The aim of this study was to assess the nutritional status of Egyptian children with end-stage renal disease (ESRD on regular hemodialysis (HD. The study included 50 Egyptian children with ESRD on regular HD, following-up at the Pediatric Nephrology unit, Cairo University. History, including dietary history, was taken for all patients and clinical examination was performed on all of them. Body weight, standing height, height or length SD score, the skin fold thickness, mid-arm circumference, mid-arm muscle circumference and mid-arm muscle circumference area were also assessed. The height of the patients was the most affected anthropometric parameter, as 78% of the patients were shorter (height SDS below -3. Body weight is less affected than height, as body weight SDS of 34% of patients was less than -3 SDS. In addition, the body mass index of 16% of the patients was 97 th percentile. Although most ESRD patients received adequate protein and caloric intake, their growth was markedly affected, especially with longer period on HD. We suggest that assessment of growth parameters should be performed at a minimum period of every six months in children with CKD stages 2-3. For children with more advanced CKD (stages 4-5 and 5D, more frequent evaluation may be warranted due to the greater risk of abnormalities.

    Treatment guidelines for colon cancer recommend colectomy with lymphadenectomy of at least 12 lymph nodes for patients with stage I to stage III disease as surgery adherence (SA) and adjuvant chemotherapy for individuals with stage III disease. Herein, the authors evaluated adherence to these guidelines among older patients in Texas with colon cancer and the associated survival outcomes. Using Texas Cancer Registry data linked with Medicare data, the authors included patients with AJCC stage II and III colon cancer who were aged ≥66 years and diagnosed between 2001 and 2011. SA and adjuvant chemotherapy adherence rates to treatment guidelines were estimated. The chi-square test, general linear regression, survival probability, and Cox regression were used to identify factors associated with adherence and survival. The rate of SA increased from 47.2% to 84% among 6029 patients with stage II or stage III disease from 2001 to 2011, and the rate of adjuvant chemotherapy increased from 48.9% to 53.1% for patients with stage III disease during the same time period. SA was associated with marital status, tumor size, surgeon specialty, and year of diagnosis. Patient age, sex, marital status, Medicare state buy-in status, comorbidity status, and year of diagnosis were found to be associated with adjuvant chemotherapy. The 5-year survival probability for patients receiving guideline-concordant treatment was the highest at 87% for patients with stage II disease and was 73% for those with stage III disease. After adjusting for demographic and tumor characteristics, improved cancer cause-specific survival was associated with the receipt of stage-specific, guideline-concordant treatment for patients with stage II or stage III disease. The adherence to guideline-concordant treatment among older patients with colon cancer residing in Texas improved over time, and was associated with better survival outcomes. Future studies should be focused on identifying interventions to

    The objective of this study was twofold: 1) to evaluate the reliability of the Walking Index for Spinal Cord Injury II (WISCI-II) and Spinal Cord Independence Measure (SCIM) indoor mobility item (#12) when used with children with spinal cord injury (SCI) and 2) to examine the concurrent validity between the WISCI-II and the SCIM indoor mobility item in children with SCI. A convenience sample of 10 children with SCI between 4-16 years of age was recruited to complete 2 videotaped trials of ambulation for 10 meters. Six licensed physical therapists trained in the use of the WISCI-II and SCIM served as raters; each rater independently scored the WISCI-II and SCIM indoor mobility item for each of the subjects' two trials by reviewing the videotape. The viewing and scoring of Trial 1 and Trial 2 were separated by at least 3 weeks. Inter- and intra-rater reliability was calculated using Intraclass Correlation Coefficients (ICC) and 95% Confidence Intervals (CI). Concurrent validity was evaluated using the Spearman Correlation Coefficient (r_{s}). Intra-rater and inter-rater reliability of repeated WISCI-II scores was high (ICC=0.98, CI=0.95-0.99; ICC=0.97, CI=0.96-0.99, respectively). Intra- and inter-rater reliability for the SCIM mobility score was equally high (ICC=0.96, CI=0.95-0.98, ICC=0.97, CI=0.95-0.98). There was strong correlation between WISCI-II scores and the SCIM indoor mobility item (r_{s}=0.99). In this sample of 10 children and six trained raters, intra- and inter-rater reliability of WISCI-II scores and the SCIM mobility indoors scores was high, providing preliminary indication for their utility with children. The high correlation between the WISCI-II and SCIM mobility item further supports concurrent validity.

    Pretreatment lymphocyte count (LC) has been associated with prognosis and chemotherapy response in several cancers. The predictive value of LC for stage II colorectal cancer (CRC) and for high-risk patients treated with adjuvant chemotherapy (AC) has not been determined. A retrospective review of prospectively collected data from 1332 consecutive stage II CRC patients who underwent curative tumor resection was conducted. A pretreatment LC value risk, 459 (62.2%) of whom received AC. Patients with low LCs had significantly worse 5-year OS (74.6% vs. 90.2%, p risk patients with low LCs had the poorest DFS (p value or combined with high-risk status were both independent prognostic factors(p risk, AC-treated patients with high LCs had significantly longer DFS than untreated patients (HR, 0.594; 95% CI, 0.364-0.970; p = 0.035). There was no difference or trend for DFS or OS in patients with low LCs, regardless of the use of AC (DFS, p = 0.692; OS, p = 0.522). Low LC was also independently associated with poorer DFS in high-risk, AC-treated patients (HR, 1.885; 95% CI, 1.112-3.196; p = 0.019). Pretreatment LC is an independent prognostic factor for survival in stage II CRC. Furthermore, pretreatment LC reliably predicts chemotherapeutic efficacy in high-risk patients with stage II CRC.

    To evaluate factors associated with the lack of adjuvant chemotherapy after curative surgery in patients with stage II and III colon cancer based on national population-based data. A total of 8,412 patients diagnosed with stage II or III disease who underwent curative resection were included. Adjuvant chemotherapy was not administered in 3,057 cases (36.34%). Factors associated with the lack of chemotherapy were older age [hazard ratio (HR)=1.50 in patients 65-74 years and 5.23 in patients ≥75 years of age], female sex (HR=1.15), tumor-node-metastasis (TNM) stage II (HR=4.28), emergency surgery (HR=1.45), American Society of Anesthesiologists (ASA) score of 3 or higher (HR=1.62), fewer than 12 lymph nodes examined (HR=1.19), a greater quantity of transfusion (HR=1.08), and hospital type (tertiary referral center) (HR=1.62). Patient-related (older age, female sex, and ASA score of 3 or higher) and treatment-related factors (TNM stage II, emergency surgery, fewer than 12 lymph nodes examined, a greater quantity of transfusion, and hospital type) influenced the lack of adjuvant chemotherapy. Given that the use of adjuvant chemotherapy improves overall survival, physicians should make an effort to increase the proportion of patients receiving chemotherapy after surgery.

    Approximately 25% of all patients with stage II colorectal cancer will experience recurrent disease and subsequently die within 5 years. MicroRNA-21 (miR-21) is upregulated in several cancer types and has been associated with survival in colon cancer. In the present study we developed a robust...... in situ hybridization assay using high-affinity Locked Nucleic Acid (LNA) probes that specifically detect miR-21 in formalin-fixed paraffin embedded (FFPE) tissue samples. The expression of miR-21 was analyzed by in situ hybridization on 130 stage II colon and 67 stage II rectal cancer specimens. The mi...... relative to the nuclear density (TBR) obtained using a red nuclear stain. High TBR (and TB) estimates of miR-21 expression correlated significantly with shorter disease-free survival (p = 0.004, HR = 1.28, 95% CI: 1.06-1.55) in the stage II colon cancer patient group, whereas no significant correlation...

    The primary prevention measure for influenza infection has been the use of influenza vaccines. However, even when the vaccine and circulating strains are well-matched, some healthy children do not respond to the vaccine, likely due to a genetic basis for immune hyporesponsiveness. The primary objective of this study was to identify HLA class II genes associated with clinical hyporesponsiveness after trivalent inactivated influenza vaccine (TIV) in children. We conducted a case-control study nested within a retrospective cohort of children that were screened at birth for HLA-DR,DQ genotypes by the Diabetes Autoimmunity Study in the Young (DAISY) and were subsequently followed for up to 8 years by Kaiser Permanente, Colorado (KPCO). Hyporesponsiveness was clinically defined as the occurrence of influenza or influenza-like illness (ILI) in peak influenza weeks in children fully vaccinated with TIV. Each child with clinical hyporesponse (n=252) was matched to 4 randomly selected controls (n=1006) by age and season. Children with clinical hyporesponse to TIV were identified using the Kaiser electronic clinical and immunization databases. Fully vaccinated children within the KPCO-DAISY cohort who did not have a diagnosis of ILI during the entire influenza season were eligible to be controls for that season. Class II HLA-DRB1 and HLA-DQB1 genes were the primary exposure variables. We used conditional logistic regression to calculate the matched odds ratios. In non-Hispanic white children, HLA-DR7/4,DQB1 0302 genotype was significantly associated (OR=5.15; 95% CI=1.94, 13.67; p=0.001), while in Hispanic children, HLA-DRB1 15 or 16 allele (OR=0.31; 95% CI=0.14, 0.69; p=0.004) and HLA-DR7/Y (DRB1 11, DRB1 13 and DRB1 14) genotype (OR=5.84; 95% CI=1.68, 20.28; p=0.006) were significantly associated with clinical hyporesponsiveness after TIV. HLA class II genes are associated with clinical hyporesponsiveness to TIV. This finding is important as it may help identify a group of

    To develop and crossvalidate new equations for predicting basal metabolic rate (BMR) in obese children and adolescents in relation to pubertal stages, anthropometric characteristics or body composition. A total of 1696 obese Caucasian children and adolescents (mean body mass index z-score: 3.5±0.8) participated in this study. BMR was determined by indirect calorimetry and fat-free mass (FFM) and fat mass (FM) by bioelectrical impedance analysis. Equations were derived by stepwise multiple regression analysis using a calibration cohort of 848 subjects, and the equations were crossvalidated with a Bland and Altman method in the remaining 848 subjects. Two new specific equations based on gender (1: males; 0: females), pubertal stages (from 1 to 5, assessed according Marshall & Tanner methods) and body weight (BW, kg), stature (m) or body composition (kg) were generated as follows: (1) BMR=(BW × 0.044)+(stature × 2.836)-(pubertal stage × 0.148)+(gender × 0.781)-0.551 (adjusted coefficient of determination (R(2)adj)= 0.69 and root mean squared error (RMSE)=0.954 MJ); (2) BMR=(FFM × 0.082)+(FM × 0.037)-(pubertal stage × 0.125)+(gender × 0.706)+2.528 (R(2)adj= 0.70 and RMSE=0.943 MJ). In the crossvalidation group, mean-predicted BMR was not significantly different from the mean-measured BMR (MBMR) for all children and adolescents, as well as for boys and girls (differenceBMR was predicted accurately (90-110% of MBMR) in 67% of subjects. The new prediction equations considering the pubertal stages allow an accurate and more appropriate (vs equations using chronological age) estimation of BMR in obese children and adolescents.

    Time-to-surgery from cancer diagnosis has increased in the United States. We aimed to determine the association between time-to-surgery and oncologic outcomes in patients with resectable pancreatic ductal adenocarcinoma undergoing upfront surgery. The 2004-2012 National Cancer Database was reviewed for patients undergoing curative-intent surgery without neoadjuvant therapy for clinical stage I-II pancreatic ductal adenocarcinoma. A multivariable Cox model with restricted cubic splines was used to define time-to-surgery as short (1-14 days), medium (15-42), and long (43-120). Overall survival was examined using Cox shared frailty models. Secondary outcomes were examined using mixed-effects logistic regression models. Of 16,763 patients, time-to-surgery was short in 34.4%, medium in 51.6%, and long in 14.0%. More short time-to-surgery patients were young, privately insured, healthy, and treated at low-volume hospitals. Adjusted hazards of mortality were lower for medium (hazard ratio 0.94, 95% confidence interval, .90, 0.97) and long time-to-surgery (hazard ratio 0.91, 95% confidence interval, 0.86, 0.96) than short. There were no differences in adjusted odds of node positivity, clinical to pathologic upstaging, being unresectable or stage IV at exploration, and positive margins. Medium time-to-surgery patients had higher adjusted odds (odds ratio 1.11, 95% confidence interval, 1.03, 1.20) of receiving an adequate lymphadenectomy than short. Ninety-day mortality was lower in medium (odds ratio 0.75, 95% confidence interval, 0.65, 0.85) and long time-to-surgery (odds ratio 0.72, 95% confidence interval, 0.60, 0.88) than short. In this observational analysis, short time-to-surgery was associated with slightly shorter OS and higher perioperative mortality. These results may suggest that delays for medical optimization and referral to high volume surgeons are safe. Published by Elsevier Inc.

    Full Text Available Today diseases of the cardiovascular system are called the problem number 1in the world, including Ukraine. Every year more than 500 thousand Ukrainians dye from CVDs, i.e. 1370 people on average dye every day. Smoking is one of the most serious threats to health, especially with regard to cardiovascular disease. Every year, smoking kills more than 1.2 million people in Europe (of which 450 thousand - due to cardiovascular diseases and about 650 thousand people of the EU countries (including from cardiovascular problems - 185 thousand. Analysis of the literature suggests paucity and contradictory information about changes in the functional status of the various systems of the body while smoking. The aim of the work was to study the peculiarities of cerebral hemodynamics in patients with hypertension stage II depending on smoking status. Material and methods. We examined 100 patients with essential hypertension stage II low additional cardiovascular risk, 53 men and 47 women. Depending on the smoking status (at least 10 years, all patients were divided into 2 groups: a group of smokers included 30 patients, in the group of non-smokers there were 70 patients. To assess cerebral hemodynamic Doppler ultrasound and duplex scanning methods were used. Statistical processing of the material was performed using the software package Statistica 6.0 («Statsoft», USA, № license AXXR712D833214FAN5. Results and discussion. Analysis of the data shows the predominance of authentic vascular resistance index in the right CCA by 3.3% (p = 0.033, in the right MCA by 8.5% (p = 0.05, in the left MCA by 7.1% (p = 0.042 in hypertensive patients with smoking status, compared with non-smoking hypertensive patients. In smokers with hypertension statistically significant increasing of the indicator "reserve vasoconstriction" by 4.63 times (p = 0.029 in the left ICA and by 3.01 times (p = 0.031 in the right ICA was also found compared with data rates in nonsmokers

    Preoperative oral capecitabine plus radiotherapy has been progressively adopted in oncology units to provide more convenient care to patients with rectal cancer, but little is known about adherence to this therapy. Prospective, multicentre observational study in six hospitals in metropolitan Barcelona (Spain), in patients with stage II and III rectal cancer. Assessment of adherence was based on the medical report in the clinical history, a patient questionnaire and a pill count in the pharmacy service upon finalization of treatment. Patients were considered adherent if they had taken 80%-110% of the prescribed treatment. We evaluated clinical variables, adverse effects, anxiety and depression (using the hospital anxiety depression scale [HADS]), and quality of life (EORTC QLQ-30). We analysed adherence-associated variables using a logistic regression model and concordance between adherence measures by means of the modified Kappa index. We included 119 participants. Adherence measures showed little concordance between the assessment methods used: adherence was 100% according to the clinical history, 83.2% according to self-report and 67.9% according to the pill count. In the multivariable analysis, the most relevant variable associated with non-adherence was anxiety prior to treatment (adjusted odds ratio [ORa] 6.96, 95% confidence interval [CI] 1.48-32.7). We did not observe any relevant association between adherence and clinical variables and baseline quality of life parameters. Adherence to short-term oral neoadjuvant treatment in rectal cancer may be a clinical problem, and it should be acknowledged and systematically evaluated by clinicians during treatment. The limited concordance between different measures of adherence highlights the challenges in monitoring it and the need to use different approaches to assess its impact in clinical practice. © The Author 2017.

    End stage renal disease (ESRD) is a worldwide devastating health problem due to its increased prevalence in the population and high association with several pathologic conditions including immunodeficiency, which makes a significant contribution to morbidity and mortality. The present study aimed at analysis of T and B lymphocyte subpopulation and the detection of flowcytometric apoptosis markers on peripheral B and T lymphocytes in a cohort of children with ESRD. A case-control study was conducted on 28 children with ESRD. In addition, 30 age and sex matched healthy children were included as a control group. We used Annexin V-FITC binding assay as a sensitive probe for identifying cells undergoing apoptosis. Circulating neutrophils, T and B lymphocytes were lower in patient group. In addition, apoptotic B and T lymphocytes occurred more frequently in children with ESRD than in the control group. Our finding of low numbers of circulating neutrophils, T and B lymphocytes, and increased portion of apoptotic B and T lymphocytes in children with ESRD, may emphasize the fact that these derangements are the main mechanisms responsible for the impairment of the immune system in ESRD children, also it adds to the fact that both cellular and humoral immunity affected in ESRD children. Finally, uremia and increased peripheral lymphocyte apoptosis were the major causes of lymphocyte populations' depletion in our ESRD patients.

    The aim of this study was to determine whether pretreatment status of thymidine phosphorylase (TP), and hypoxia-inducible factor alpha (HIF-1α) could predict pathologic response to neoadjuvant chemoradiation therapy with oxaliplatin and capecitabine (XELOXART) and outcomes for clinical stage II/III rectal cancer patients. A total of 180 patients diagnosed with clinical stage II/III rectal cancer received XELOXART. The status of TP, and HIF-1α were determined in pretreatment biopsies by immunohistochemistry (IHC). Tumor response was assessed in resected regimens using the tumor regression grade system and TNM staging system. 5-year disease free survival (DFS) and 5-year overall survival (OS) were evaluated with the Kaplan-Meier method and were compared by the log-rank test. Over expression of TP and low expression of HIF-1α were associated with pathologic response to XELOXART and better outcomes (DFS and OS) in clinical stage II/III rectal cancer patients (P rectal cancer received XELOXART. Additional well-designed, large sample, multicenter, prospective studies are needed to confirm the result of this study.

    OBJECTIVE To determine histologic and clinical factors associated with survival time in dogs with stage II splenic hemangiosarcoma treated by splenectomy and a chemotherapy protocol in which an anthracycline was alternated with lomustine. DESIGN Retrospective case series. ANIMALS 30 dogs with stage II splenic hemangiosarcoma. PROCEDURES Medical records of 3 facilities were reviewed to identify dogs treated for stage II splenic hemangiosarcoma between June 2011 and October 2014. Information collected included signalment, disease staging data, whether anemia was present, date of splenectomy, chemotherapy protocol, adverse effects, and date of death or last follow-up. Histologic slides were reviewed and scored by pathologists. Associations between variables of interest and survival data were evaluated statistically. RESULTS Median survival time for all dogs was 158 days (range, 55 to 560 days), and the 1-year survival rate was 16%. On multivariate analysis, only the histologically determined mitotic score was significantly associated with survival time. The median survival time of 292 days for dogs with a mitotic score of 0 (hemangiosarcoma.

    Health-related quality of life (HRQOL) is an essential subject for children with end-stage renal disease (ESRD) and their families. We performed a cross-sectional investigation of HRQOL in children undergoing renal replacement therapies, such as dialysis and renal transplantation, using the 34-item Pediatric Quality of Life Inventory 3.0 End-Stage Renal Disease (PedsQL 3.0 ESRD) module. We assessed 92 ESRD patients aged 2-18 from four Korean university hospitals. The male:female ratio was 44:48, and the most common cause of ESRD was chronic glomerulonephritis. Fifty-five children were treated by dialysis, and 37 received renal transplantation. Transplant patients had better HRQOL than dialysis patients in two domains in parent proxy reports: "About my kidney disease" and "Worry." In child self-reports, transplant patients had better HRQOL than dialysis patients in one domain: Treatment problems. However, there were no significant differences in total QOL scores between peritoneal dialysis (PD) and transplant patients in child self-reports. In addition, there were differences in the ESRD module scores between child self- and parent proxy reports. Children usually reported better QOL than their parents. Child self-reports showed significantly higher QOL scores than parent proxy reports in the domains of General fatigue, Family & peer interaction, and Worry. Children on PD self-reported a significantly higher QOL than children on hemodialysis (HD). The PedsQL 3.0 ESRD module may be useful as an ESRD-specific instrument to evaluate HRQOL in children; however, a larger, longitudinal prospective study is warranted.

    Full Text Available Statement of Problem: Considerable response to functional orthopedic appliances treatment in class II skeletal patients occurs during pubertal growth spurt. Therefore, it seems necessary to investigate indices indicating mandibular growth pattern. It has been proved that analyzing cervical vertebral maturation stage is a more valid index than that of hand wrist. Purpose: The aim of this study was to evaluate the time status of functional orthopedic treatment in class II skeletal patients using CVMS index. Materials and Methods: In this descriptive-inferential study, lateral cephalometric radiographs of 153 class II skeletal patients with mandibular deficiency, before treatment, were studied by an oral and maxillofacial radiologist using the index of cervical vertebral maturation stage (CVMS and were categorized in three phases: CVMS I (desirable phase of treatment, CVMS II (ideal phase, and CVMS III (undesirable phase of treatment. Results: Statistical analysis ranked the prevalence of treatment phases as: 41.8% in desirable phase (CVMS I, 28.1% in ideal phase (CVMA II and 30% in undesirable phase (CVMS III. No significant differences were found between the three phases using Chi-square analysis. Time status of functional orthopedic treatment was also evaluated based on age and sex. The results showed significant differences between two sexes (P=0.032. Conclusion: The present study suggests the analysis of CVMS index, along with clinical criteria, in the determination of an ideal time for functional orthopedic treatment to prevent patients’ exhaustion during treatment Period.

    2012-07-01

    Full Text Available Abstract Background Adjuvant chemotherapy for stage III colon cancer is internationally accepted as standard treatment with established efficacy, but the usefulness of adjuvant chemotherapy for stage II colon cancer remains controversial. The major Western guidelines recommend adjuvant chemotherapy for “high-risk stage II” cancer, but this is not clearly defined and the efficacy has not been confirmed. Methods/design SACURA trial is a multicenter randomized phase III study which aims to evaluate the superiority of 1-year adjuvant treatment with UFT to observation without any adjuvant treatment after surgery for stage II colon cancer in a large population, and to identify “high-risk factors of recurrence/death” in stage II colon cancer and predictors of efficacy and adverse events of the chemotherapy. Patients aged between 20 and 80 years with curatively resected stage II colon cancer are randomly assigned to a observation group or UFT adjuvant therapy group (UFT at 500–600 mg/day as tegafur in 2 divided doses after meals for 5 days, followed by 2-day rest. This 1-week treatment cycle is repeated for 1 year. The patients are followed up for 5 years until recurrence or death. Treatment delivery and adverse events are entered into a web-based case report form system every 3 months. The target sample size is 2,000 patients. The primary endpoint is disease-free survival, and the secondary endpoints are overall survival, recurrence-free survival, and incidence and severity of adverse events. In an additional translational study, the mRNA expression of 5-FU-related enzymes, microsatellite instability and chromosomal instability, and histopathological factors including tumor budding are assessed to evaluate correlation with recurrences, survivals and adverse events. Discussion A total of 2,024 patients were enrolled from October 2006 to July 2010. The results of this study will provide important information that help to improve the

    We adopted ABVD chemotherapy with risk-adapted radiation therapy (RT) as first-line therapy for children, adolescents and young adults with Hodgkin lymphoma (HL) in British Columbia in 2004. Patients ≤ 25 years diagnosed from 2004 to 2013 with all stages of HL who received ABVD as initial therapy were included. Among 55 children (age young adults (18-25 year), there were no significant differences among age groups for sex, histologic subtype, tumour bulk, B symptoms, prognostic risk groups or treatment received. The rates of complete response, partial response and progressive disease were 84%, 7% and 10% for children and 95%, 4% and 1% for young adults (P=0.01), respectively. Treatment failures in children all occurred within one year of completion, while 8/21 (38%) relapses in young adults occurred later (P=0.04). With a median follow-up of 66 months the 5-year progression-free (PFS) and overall survival (OS) were 85 ± 3% and 97 ± 1%, respectively. For limited stage disease, PFS was 90 ± 7% for children and 93 ± 3% for young adults (P=0.65); OS was 100% for both. For advanced stage patients, PFS and OS were also similar for the children and young adults (77 ± 7% versus 81 ± 4%; P=0.38 and OS 90 ± 6% versus 97 ± 2%; P=0.17). The rate of consolidative RT was low (21%) and did not differ between age groups. ABVD is an effective treatment in children, adolescents and young adults with HL. Children were less likely to achieve complete response and demonstrated earlier relapses compared to young adults. RT may be omitted for the majority of patients while maintaining excellent 5-year OS. © The Author 2017. Published by Oxford University Press on behalf of the European Society for Medical Oncology.

    This study aimed to demonstrate that dietary intake, anthropometric indicators, and body composition in children with end-stage kidney disease differs between those on peritoneal dialysis (PD) and those on hemodialysis (HD). This was a cross-sectional and consecutive study that included 55 children and adolescents with end-stage kidney disease who were undergoing replacement therapy (22 PD patients and 33 HD patients). Two 24-hour dietary recall surveys were conducted for each patient. Anthropometric, biochemical, and body composition indicators were estimated. A Student's t-test and a Mann-Whitney U test were used for the parametric variables, whereas association tests were estimated for the nonparametric variables (i.e., χ 2 , Fisher exact test, and odds ratio). Regression models were designed to predict dietary intake on anthropometric and body composition indicators. The mid-upper arm circumference was greater on the patients undergoing HD than on the PD patients (odds ratio = 15.8 [95% confidence interval (CI): 2.9, 85.1], P nutritional status in children on PD and 28% to 60% in children on HD. Nutritional status is affected in most patients on dialysis treatment, which differs significantly among those who are undergoing PD or HD. Copyright © 2017 National Kidney Foundation, Inc.

    The identification of early-stage colorectal cancer (CRC) with high risk of progression is one major clinical challenge, mainly due to lack of validated biomarkers. The aims of the present study were to analyze the prognostic impact of three molecular markers belonging to the ion channels and transporters family: the ether-à-go-go-related gene 1 (hERG1) and the calcium-activated KCa3.1 potassium channels, as well as the glucose transporter 1 (Glut-1); and to define the impact of adjuvant chemotherapy in conjunction with the abovementioned biomarkers, in a cohort of radically resected stage I-III CRC patients. The expressions of hERG1, KCa3.1, and Glut-1 were tested by immunohistochemistry on 162 surgical samples of nonmetastatic, stage I-III CRC patients. The median follow-up was 32 months. The association between biological markers, clinicopathological features, and survival outcomes was investigated by evaluating both disease-free survival and overall survival. Although no prognostic valence emerged for KCa3.1, evidence of a negative impact of hERG1 expression on survival outcomes was provided. On the contrary, Glut-1 expression had a positive impact. According to the results of the multivariate analysis, patients were stratified in four risk groups, based on TNM stage and hERG1/Glut-1 expression. After adjusting for adjuvant therapy, stage I and II, Glut-1-negative, and hERG1-positive patients showed the worst survival experience. This study strongly indicates that the combination of hERG1 positivity and Glut-1 negativity behaves as a prognostic biomarker in radically resected CRC patients. This combination identifies a group of stage I and II CRC patients with a bad prognosis, even worse than that of stage III patients, regardless of adjuvant therapy accomplishment.

    Background and Aims. As a first step toward understanding the increasing incidence of colorectal cancer (CRC) in younger (age < 50) populations, we examined demographic, clinicopathologic, and socioeconomic characteristics and treatment receipt in a population-based sample of patients newly diagnosed with stages II and III CRC. Methods. Patients were sampled from the National Cancer Institute's Patterns of Care studies in 1990/91, 1995, 2000, 2005, and 2010 (n = 6, 862). Tumor characteristics...

    In Stage II colon cancer, multiple independent studies have shown that a dense intratumoural immune infiltrate (local inflammation) is associated with improved outcomes, while systemic inflammation, measured by various markers, has been associated with poorer outcomes. However, previous studies have not considered the interaction between local and systemic inflammation, nor have they assessed the type of inflammatory response compared with standard clinicopathologic criteria. In order to evaluate the potential clinical utility of inflammatory markers in Stage II colon cancer, we examined local and systemic inflammation in a consecutive series of patients with resected Stage II colon cancer between 2000 and 2010 who were identified from a prospective clinical database. Increased intratumoural chronic inflammatory cell (CIC) density, as assessed by pathologist review of hematoxylin and eosin stained slides, was used to represent local inflammation. Neutrophil-to-lymphocyte ratio (NLR) >5, as calculated from pre-operative full blood counts, was used to represent systemic inflammation. In 396 eligible patients identified, there was a non-significant inverse relationship between local and systemic inflammation. Increased CIC density was significantly associated with improved overall (HR 0.45, p = 0.001) and recurrence-free survival (HR 0.37, p = 0.003). High NLR was significantly associated with poorer overall survival (HR 2.56, p < 0.001). The combination of these markers further stratified prognosis independent of standard high-risk criteria, with a dominant systemic inflammatory response (low CIC/high NLR) associated with the worst outcome (5-year overall survival 55.8%). With further validation this simple, inexpensive combined inflammatory biomarker might assist in patient selection for adjuvant chemotherapy in Stage II colon cancer. © 2015 UICC.

  3. Atypical Bilateral Brain Synchronization in the Early Stage of Human Voice Auditory Processing in Young Children with Autism.

    Full Text Available Autism spectrum disorder (ASD has been postulated to involve impaired neuronal cooperation in large-scale neural networks, including cortico-cortical interhemispheric circuitry. In the context of ASD, alterations in both peripheral and central auditory processes have also attracted a great deal of interest because these changes appear to represent pathophysiological processes; therefore, many prior studies have focused on atypical auditory responses in ASD. The auditory evoked field (AEF, recorded by magnetoencephalography, and the synchronization of these processes between right and left hemispheres was recently suggested to reflect various cognitive abilities in children. However, to date, no previous study has focused on AEF synchronization in ASD subjects. To assess global coordination across spatially distributed brain regions, the analysis of Omega complexity from multichannel neurophysiological data was proposed. Using Omega complexity analysis, we investigated the global coordination of AEFs in 3-8-year-old typically developing (TD children (n = 50 and children with ASD (n = 50 in 50-ms time-windows. Children with ASD displayed significantly higher Omega complexities compared with TD children in the time-window of 0-50 ms, suggesting lower whole brain synchronization in the early stage of the P1m component. When we analyzed the left and right hemispheres separately, no significant differences in any time-windows were observed. These results suggest lower right-left hemispheric synchronization in children with ASD compared with TD children. Our study provides new evidence of aberrant neural synchronization in young children with ASD by investigating auditory evoked neural responses to the human voice.

    Nearly 20% patients with stage II A colon cancer will develop recurrent disease post-operatively. The present study aims to develop a scoring system based on Artificial Neural Network (ANN) model for predicting 10-year survival outcome. The clinical and molecular data of 117 stage II A colon cancer patients from Sun Yat-sen University Cancer Center were used for training set and test set; poor pathological grading (score 49), reduced expression of TGFBR2 (score 33), over-expression of TGF-β (score 45), MAPK (score 32), pin1 (score 100), β-catenin in tumor tissue (score 50) and reduced expression of TGF-β in normal mucosa (score 22) were selected as the prognostic risk predictors. According to the developed scoring system, the patients were divided into 3 subgroups, which were supposed with higher, moderate and lower risk levels. As a result, for the 3 subgroups, the 10-year overall survival (OS) rates were 16.7%, 62.9% and 100% (P < 0.001); and the 10-year disease free survival (DFS) rates were 16.7%, 61.8% and 98.8% (P < 0.001) respectively. It showed that this scoring system for stage II A colon cancer could help to predict long-term survival and screen out high-risk individuals for more vigorous treatment. PMID:27008710

    Compared with white children, the oral health of Latino children in the United States is much worse. One factor contributing to oral health is tooth brushing. Few studies have addressed the formation of the tooth brushing habit in children, and only one of them studied a Latino population. The purpose of this study is to explore the development of the tooth brushing habit in children of Mexican immigrant families and develop hypothesis based on its results. This is an exploratory qualitative study, with a case study design based on 20 in-depth interviews. Participants were Mexican immigrant mothers living in Pittsburgh and Philadelphia, PA. Participants had at least one child six-years-old or younger. Interviews were recorded, transcribed verbatim, and analyzed using qualitative analysis procedures. Four stages were identified in the tooth brushing learning process: initiation and entirely dependent tooth brushing, assisted tooth brushing, road to tooth brushing independence, and independent tooth brushing. Two factors influenced parents' teaching approaches: parents' perceptions of their child's achievement of physical, cognitive, and motor developmental milestones and parents' knowledge about oral hygiene. We identified four distinct stages and found evidence to hypothesize that transitions from one stage to the next are triggered not by the age of the child but by parents' knowledge about oral hygiene and their perceptions of their child's achievement of physical, cognitive, and motor developmental milestones. Future quantitative research studies should be conducted to test this hypothesis in larger groups of Latinos as well as other ethnic groups. © 2015 American Association of Public Health Dentistry.

    Purpose: To investigate influence of various pretreatment prognostic factors in patients with early stage (I/II) non-small-cell lung cancer (NSCLC) treated with hyperfractionated radiation therapy alone. Patients and Methods: One hundred and sixteen patients were treated with tumor doses of 69.6 Gy, 1.2-Gy, twice-daily fractionation. There were 49 patients with Stage I and 67 patients with Stage II. Eighty patients had Karnofsky performance status (KPS) 90-100 and 95 patients had <5% weight loss. Peripheral tumors were observed in 57 patients. Squamous histology was observed in 70 patients and the majority of patients had concomitant disease (n = 72). Results: The median survival time for all patients was 29 months; 5-year survival was 29%. The median time to local progression and the distant metastasis were not achieved, whereas 5-year local progression-free and distant metastasis-free survivals were 50% and 72%, respectively. Multivariate analysis identified KPS, weight loss, location, histology, and the reason for not undergoing surgery as prognostic factors for survival. KPS, location, and histology influenced local progression-free survival, whereas only KPS and weight loss influenced distant metastasis-free survival. Conclusions: This retrospective analysis identified KPS and weight loss as the most important prognostic factors of outcome in patients with early-stage NSCLC treated with hyperfractionation radiation therapy

    The optimal surgical approach (wide local excision (WLE) vs. Mohs micrographic surgery (MOHS)) for treating Merkel cell carcinoma (MCC) is yet to be determined. To compare survival outcomes in patients with early stage MCC treated with MOHS versus WLE. A retrospective review of all cases in the National Cancer Data Base (NCDB) of MCC of clinical Stage I-II MCC treated with WLE or MOHS was performed. 1,795 cases of Stage I-II MCC were identified who underwent WLE (N=1,685) or MOHS (N=110). There was no difference in residual tumor on surgical margins between the two treatment groups (p=0.588). On multivariate analysis, there was no difference in overall survival between the treatment modalities (adjusted HR 1.02; 95% CI 0.72-1.45, p=0.897). There was no difference in overall survival between the two groups on propensity score matched analysis. Disease specific survival was not reported as this data in not available in the NCDB. MOHS appears to be as effective as WLE in treating early stage MCC. Copyright © 2018. Published by Elsevier Inc.

    The risk of progressing to end-stage kidney disease (ESKD) and factors associated with progression in children with chronic kidney disease (CKD) are unclear, especially in Asian children. We started a nationwide, prospective cohort study of 447 Japanese children with pre-dialysis CKD in 2010, with follow-up in 2011. Progression to ESKD was analyzed by Kaplan-Meier analysis according to CKD stage. Cox regression analysis was used to identify risk factors for progression. Data were analyzed for 429/447 children. Five patients died, of which four died before progression to ESKD. Fifty-two patients progressed to ESKD (median follow-up 1.49 years), including 9/315 patients with stage 3 CKD, 29/107 with Stage 4 CKD and 14/25 with Stage 5 CKD. One-year renal survival rates were 98.3, 80.0 and 40.9%, for Stages 3, 4 and 5 CKD, respectively. Risk factors for progression to ESKD included CKD stage [versus Stage 3; Stage 4: hazard ratio (HR) 11.12, 95% confidence interval (CI) 4.22-29.28, P 2.0 g/g urine creatinine; HR 7.56, 95% CI 3.22-17.77, P children with pre-dialysis CKD progressed to ESKD with a median-follow-up of 1.49 years. Children with advanced (Stage 4/5) CKD were particularly likely to progress. To our knowledge, this is the first, nationwide, prospective cohort study of children with pre-dialysis CKD in Asia.

    Cardiovascular disease is the leading cause of death in children with end-stage renal disease (ESRD). Isolated aortic dilation (AD) is rare in children. We aimed to determine the prevalence and the risk factors for AD in children with ESRD. We reviewed records of all ESRD patients followed mat our institution from January 2007 to October 2012. AD was defined as Z-score > 2 in the dimension of at least one of the following echocardiographic aortic parameters: annulus, root at the sinus, sino-tubular junction, or ascending aorta. The records of 78 patients on dialysis and 19 kidney transplant recipients were available. 30 patients (30.9%) had AD. Multivariate analysis revealed independent associations of AD with body mass index (BMI) Z-score (OR = 0.52, 95% confidence interval (CI): 0.35 - 0.78) and ESRD secondary to glomerular disease (OR = 4.58, 95% CI: 1.45 - 14.46). We developed a classification and regression tree (CART) model to identify patients at low vs. high AD risk. Our model classified 62 patients of the cohort (64%) to be high- or lowrisk, with a positive predictive value of 89% and a negative predictive value of 100%. Our data suggest that AD, as a possible marker of aortopathy and early aneurysm formation, is a novel and prevalent cardiovascular complication in ESRD children. Glomerular disease and low BMI Zscore appear to be potent predictors. CART modeling helps identify high-risk children, potentially guiding decisions regarding targeted echocardiographic evaluations.

    A major obstacle in treating colorectal cancer (CRC) is the acquired resistance to chemotherapeutic agents. An important protein in the regulation of cancer cell death and clinical outcome is Raf kinase inhibitor protein (RKIP). In contrast, activated signal transducer and activator of transcription 3 (STAT3) is a protein that promotes tumor cell survival by inhibiting apoptosis and has an important role in cancer progression in many of cancer types. The aim of this study was to evaluate the regulation of RKIP and STAT3 after treatment with clinically relevant chemotherapeutic agents (camptothecin (CPT) and oxaliplatin (OXP)) and the cytokine interleukin-6 (IL-6) in HCT116 colon cancer cells as well as evaluate the association between RKIP and STAT3 with clinical outcome of Stage II colon cancer patients. HCT-116 colon cancer cells were treated with CPT, OXP, and IL-6 separately or in combination in a time and dose-dependent manner and examined for phosphorylated and non-phosphorylated RKIP and STAT3 via Western blot analysis. STAT3 transcriptional activity was measured via a luciferase reporter assay in HCT116 cells treated with CPT, IL-6 or transfected with JAK 1, 2 separately or in combination. We extended these observations and determined STAT3 and RKIP/ pRKIP in tumor microarrays (TMA) in stage II colon cancer patients. We demonstrate IL-6-mediated activation of STAT3 occurs in conjunction with the phosphorylation of RKIP in vitro in human colon cancer cells. OXP and CPT block IL-6 mediated STAT3 activation and RKIP phosphorylation via the inhibition of the interaction of STAT3 with gp130. We determined that STAT3 and nuclear pRKIP are significantly associated with poor patient prognosis in stage II colon cancer patients. In the analysis of tumor samples from stage II colon cancer patients and the human colon carcinoma cell line HCT116, pRKIP and STAT3, 2 proteins potentially involved in the resistance to conventional treatments were detected.

    Many studies have shown altered neuropsychological functioning of children with epilepsy even in the absence of intellectual disability, with notable concerns for both patients and their families. Although studies have described the cognitive profiles associated with specific epilepsy syndromes, there is incomplete agreement on the relation between spared and impaired abilities in different cognitive domains and on how deficits in one neuropsychological ability can secondarily affect performance in other cognitive domains. The aim of this study was to investigate the neuropsychological profile and vulnerabilities of children with epilepsy without intellectual disability or borderline intellectual functioning. 23 children aged 7-15 years, with a diagnosis of epilepsy of genetic or unknown cause and average intellectual functioning (IQ >85), were administered all age-appropriate tests of the Italian-language version (Urgesi, Campanella, & Fabbro, 2011) of a comprehensive neuropsychological battery (NEPSY-II: A Developmental Neuropsychological Assessment, Second Edition; Korkman, Kirk, & Kemp, 2007). Their performance was compared with that of a control group matched for gender, age, handedness and education. Children with epilepsy showed significant impairments as compared to the control group in tests of attention and executive functions and sensorimotor skills. Notably, particular difficulties were observed also in social perception tasks that require affect recognition, an ability that has been so far poorly considered in children with epilepsy. The results highlight the importance of performing extensive evaluation of cognitive functions, including social cognition processes, in children with epilepsy with average intelligence in order to design appropriate interventions aimed at minimizing long-term consequences on educational and behavioral outcome.

    Full Text Available Objectives: Foot arch reduces the exposure of weight and buf load due to its bufer function. in longitudinal platypodia foot looses this function and articular menisci have to take the role of the bufers (shock absorbers. Materials and Methods: Ultrasound assessment of meniscus thickness was performed on the joint space level. Results: varus type (43.4% of the meniscus complex adaptation was dominant in 5-7 years old patients with the 1st stage longitudinal platypodia; symmetric type (51.9% – in 8-12 years old patients; valgus type (56% – in 13-17 years old ones. Healthy children showed the valgus type in all age periods. Conclusions: in our opinion the dominance of the varus type of the meniscus complex in 5-7 aged children and its further conversion into the valgus type in case of the 1st stage longitudinal platypodia refects the reduction of the lower extremities transformation processes from the varus into the most functional convenient valgus position at the age of 13-17.

    Purpose: We performed a retrospective study to determine the long-term outcome, patterns of failure, and prognostic factors for patients with pathologic Stage I or II Hodgkin's disease (HD) who were treated with mantle irradiation alone. Methods and Materials: The medical records of 145 patients with pathologic Stage I or II supradiaphragmatic Hodgkin's disease treated with mantle irradiation alone between June 1967 and June 1991 were reviewed. Patterns of failure, overall survival (OS) rate, and progression-free survival (PFS) rate were determined. Univariate and multivariate analyses were performed to identify adverse prognostic factors for OS and PFS. The number of adverse prognostic factors per patient was counted, and a prognostic score was assigned to each patient. The log-rank test was used to compare the OS or PFS rates among patients with prognostic scores 0, 1, and 2. Results: The median patient age was 27 years (range 10-66), with almost even male to female distribution. Every patient had splenectomy and negative laparotomy (LAP). Fifty-one patients had Stage I disease (IA-49, IB-2) and 94 Stage II (IIA-89, IIB-5). The histologic subtypes were nodular sclerosing in 110, mixed cellularity in 28, lymphocyte predominance in 5, lymphocyte depleted in 1, and unclassified in 1. Twelve patients with Stage II disease had ≥ 3 sites of nodal involvement. Fifty-four patients had a prognostic score of 0, 70 of 1, and 21 of 2. The median follow-up time for the 109 surviving patients was 146 months (range 25-381). The 10- and 20-year actuarial OS rates for the whole group were 87.6% and 65.3%, respectively. The corresponding actuarial PFS rates were 75.3% and 74.2%, respectively. Thirty-six patients (9 Stage I, 27 Stage II) had relapses in a total of 41 sites. Failures by histology were 29 patients with nodular sclerosing, 6 with mixed cellularity, and 1 with lymphocyte predominance. Failures by sites were: trans-diaphragmatic, 22 (para-aortic nodes, 15; as the only

    Objective: A phase I study was conducted to determine the maximal tolerated dose (MTD) and the dose-limiting toxicity (DLT) of chemotherapy of oral doxifluridine (5-dFUR) and leucovorin with concurrent standard radiotherapy(RT) as adjuvant treatment in patients with rectal cancer. Methods: Patients aged 18-75 years old, Kamofsky scored ≥70%, stage II/III rectal cancer after curative surgery were eligible. Total RT dose was delivered as DT 50 Gy in the fraction of 2.0 Gy per day for 5 weeks to the pelvic area. 5-dFUR was administered concurrently with radiotherapy in escalating doses, and oral leucovorin was administered in a fixed dose of 30 mg/(m 2 ·d), both 3 times daily, from the 1 st day of RT to the last day. The DLTs included grade 3 or grade 4 hematologic and nonhematologie toxicity. Results: From Aug. 2005 to Mar. 2007, 16 patients were enrolled at the following dose levels: 450 mg/(m 2 ·d) (3 patients), 550 mg/(m 2 ·d) (6 patients) and 650 mg/(m 2 ·d) (7 patients). Diarrhea, neutropenia and nausea/vomit were the most common side effects although all neutropenia was less grade 3. The DLT was observed in 1 patient at 550 mg/(m 2 ·d) (grade 4 diarrhea), but none in the following 3 patients at the same dose level. At 650 mg/(m 2 ·d) level, the first patient quitted the study due to a severe abdominal cramp pain in the 3rd week of RT. In the following 3 enrolled patients, one suffered grade 3 abdominal cramp pain, diarrhea, fatigue, nausea/vomit and grade 2 neutropenia and fever. Grade 3 diarrhea was also observed in all the additional 3 patients at 650 mg/(m 2 ·d) dose level. So the dose escalation was ended up to 650 mg/(m 2 ·d). Four of 16 patients didn't complete the scheduled concurrent chemoradiotherapy due to severe side effects, including 1 at 550 mg/(m 2 ·d) dose level, and 3 at 650 mg/(m 2 ·d). The DLTs were observed as grade 3/4 diarrhea, grade 3 abdominal cramp pain, fatigue and nausea/vomit. Conclusions: Diarrhea is the most common and

    Purpose: We report our results using MRT for clinical stage I-II HD and assess the value of published prognostic criteria in our study population. Pts and Methods: Between 1969 and 1994, 261 pts were treated with MRT alone for clinical stage I-II supradiaphragmatic HD. Pt characteristics: median age-30; M-54%/F-46%; stage IA-52%, IB-2%, IIA-37%, IIB-8%; histology LP-21%, NS-51%, MC-23%, other 5%; median ESR 18. CT abdomen and LAG were performed in 61% and 60% respectively. No pt had prior staging laparotomy. No pt received infradiaphragmatic RT. Central axis dose was 32 Gy-36 Gy. Univariate analysis was performed for prognostic factors for progression-free (PFS) and overall survival(OS). Outcome was assessed in favourable subsets as defined by: EORTC (v. favourable: CSIA, LP or NS histology, age < 40, female, no bulk, ESR < 50; favourable: CSI-II, age < 50, < 4 sites, no bulky mediastinal mass, ESR < 50 with no B symptoms or ESR < 30 with B symptoms); Princess Margaret Hospital (PMH) (IA-IIA, LP or NS histology, ESR < 40, age < 50, no large mediastinal mass, no E lesion). Results: 261 pts completed RT, with 5% requiring treatment interruption for toxicity. Significant factors (P<0.05) for PFS were stage, performance status, histology, B symptoms, number of sites, ESR and bulk. Significant factors (P<0.05) for OS were age, performance status, histology and B symptoms. (The results of a multivariate analysis will be presented.) Results in our study population using published prognostic criteria (in %): Thirty-six percent progressed following RT: 8% in-field; 24% out of field only (including 10% in the paraaortic/splenic region alone); 4% marginal; Fifty-seven percent of relapsed pts remain progression free after subsequent salvage treatment. Two cases of acute leukaemia, 8 cases of non-Hodgkin's lymphoma and 14 (non-skin) carcinomas occurred, of which 11 were in-field. Seventy pts have died. The cause was: HD 41%; other malignancy 20%; cardiovascular 17%; other 15

    We investigated whether maximum standardized uptake value (SUVmax), metabolic tumour volume (MTV), total lesion glycolysis (TLG) and whole-body (WB) SUVmax, WB MTV and WB TLG measured by {sup 18}F-FDG PET/CT could improve prognostic stratification in patients with stage II/III breast cancer (BC). We prospectively enrolled 99 consecutive women (median age 50 years, range 27 - 77 years) with pathologically proven stage II/III BC who underwent pretreatment FDG PET/CT. WB SUVmax, WB MTV and WB TLG were measured in all malignant lesions. Survival was analysed using the Kaplan-Meier method. Cox proportional hazards models were constructed to test for relationships among WB SUVmax, WB MTV, WB TLG, and overall survival (OS) and disease-free survival (DFS), after adjustment for age, and histopathological and immunohistochemical features (oestrogen/progesterone and HER2 expression, proliferation index and grade). The median values of WB SUVmax, WB MTV and WB TLG were 16.2 (range 1.5 - 33.1), 14 cm{sup 3} (range 0.03 - 708.6 cm{sup 3}) and 62.5 (0.06 - 3869.4), respectively. All WB semiquantitative values were higher in patients with higher TNM stage, although not significantly (all p > 0.05). The median follow-up for surviving patients was 30 months, with a range of 13 - 45 months. Both PFS and OS of patients with low WB SUVmax, WB MTV and WB TLG were longer than that of patients with high WB values for progression, although not statistically significant. However, stratifying the patients in accordance with the stage of disease, both PFS and OS were significantly lower in patients with high WB TLG and stage III than in patients with stage II (p < 0.05). In multivariate analyses, WB MTV and WB TLG were independent prognostic factors for PFS (hazard ratio 1.004, 95 % confidence interval 1.002 - 1.006, p < 0.001, and hazard ratio 1.001, 95 % confidence interval 1.000 - 1.001, p = 0.011, respectively). The addition of WB TLG to clinical data may provide a more detailed

    In stage II colon cancer, patients with many retrieved lymph nodes (LNs) have been reported to have better oncological outcomes. We tested the hypothesis that the greater number of retrieved LNs is related to a larger LN size. The subjects comprised 320 patients with stage II colon cancer who underwent curative resection. All operations were elective and were performed by the same surgeons. The maximum long axis and short axis diameters of LNs were measured on hematoxylin-eosin-stained specimens. A total of 4,744 LNs were evaluated. The number of retrieved LNs was 14.8 ± 10.1 (mean ± SD). The long axis diameter was 4.8 ± 2.6 mm, with a median value of 4.3 mm, a maximum value of 20.4 mm, and a minimum value of 0.6 mm. The corresponding short axis diameters were 3.4 ± 1.7, 3.0, 15.1, and 0.5 mm, respectively. The highest correlation coefficient for the association with the number of LNs was obtained for the maximum value of the long axis diameter (0.59). Multivariate analysis revealed that age, tumor location, pathological T stage, and the maximum long axis diameter were independent prognostic factors. The number of LNs was not a significant factor. Patients with less than 12 LNs and a maximum long axis diameter of less than 10 mm had significantly poorer outcomes (p patients with stage II colon cancer, the maximum long axis diameter of LNs correlated with the number of LNs and was an independent prognostic factor.

    This paper examines the complex questions that arise around the appearance of children in contemporary performance. Drawing on performances by Nottingham-based theatre company Zoo Indigo and Tim Etchells and the Flemish theatre company Victoria, I consider the extent to which Hannah Arendt’s theorisation of natality as ‘the new beginning inherent in birth’ that gives rise to the political potential to ‘begin something anew’ can help us to understand the ethico-political dimensions of children...

    Full Text Available Background/Aims: We investigated the recently described family of proteinases, a disintegrin and metalloproteinase with thrombospondin motifs (ADAMTs, and matrix metalloproteinases (MMPs as inflammatory mediators in inflammatory kidney damage by studying ADAMTS-1, -4, and -7 and MMP-9 expression in elderly mouse kidneys after angiotensin II (Ang II administration. Methods: Ang II (2.5 µg/kg/min or norepinephrine (8.3 µg/kg/min was subcutaneously infused in old mice. Renal injury was assessed by hematoxylin-eosin staining, 24-h albuminuria, and immunohistochemistry to evaluate inflammatory cell markers. The mRNA and protein expression of ADAMTS-1, -4, and -7 and MMP-9 were determined using real-time PCR, Western blot, and immunohistochemistry 3 days after Ang II or norepinephrine administration. Results: Elderly mice in the Ang II group developed hypertension and pathological kidney damage. The mRNA and protein levels of ADAMTS-7 in the Ang II group were 3.3 ± 1.1 (P = 0.019 and 1.6 ± 0.1 (P = 0.047 vs. 1.0 ± 0.1 and 1.0 ± 0.1 in the control group on day 3. In contrast, treatment with the hypertensive agent norepinephrine did not lead to obvious renal damage or an increase in renal ADAMTS-7 expression. Conclusions: Renal ADAMTS-7 expression was induced by Ang II in elderly mice. The overexpression of ADATMTS-7 might contribute to early inflammatory kidney damage associated with aging.

    The mortality of patients with end-stage renal disease (ESRD) is much higher than that of the general population. To date no data has been published on the mortality of children with ESRD in Poland. The aim of this study was to compare the risk of death for pediatric patients on renal replacement therapy (RRT) with that of the general pediatric population and to identify the risk factors of death. Data of 779 children with ESRD registered in the Polish Registry of Children on RRT was analyzed. The relative risk of death was calculated as the ratio of the mortality rate in ESRD patients to the mortality rate in age-adjusted general population. The mortality rate of children with ESRD was 74-fold higher than that of the age- and gender-adjusted general pediatric population (4.05 vs. 0.05/100 person-years). The highest mortality rate (4.53/100 patient-years) was found in the youngest age group. Younger age and duration of dialysis therapy were identified as mortality risk factors. The major causes of death in ESRD patients were infections and cardiovascular complications, whereas deaths in general child population were mainly due to accidents or congenital defects. The mortality in Polish children with ESRD is 74-fold higher than that of the general pediatric population. Infections, followed by cardiovascular complications, constitute the main causes of mortality in children subjected to RRT. The risk of death is the highest among children who started RRT at a younger age and in those subjected to long-term dialysis treatment. Copyright © 2014 Medical University of Bialystok.

    Typically pediatric end-of-life decision-making studies have examined the decision-making process, factors, and doctors' and parents' roles. Less attention has focussed on what happens after an end-of-life decision is made; that is, decision enactment and its outcome. This study explored the views and experiences of bereaved parents in end-of-life decision-making for their child. Findings reported relate to parents' experiences of acting on their decision. It is argued that this is one significant stage of the decision-making process. A qualitative methodology was used. Semi-structured interviews were conducted with bereaved parents, who had discussed end-of-life decisions for their child who had a life-limiting condition and who had died. Data were thematically analysed. Twenty-five bereaved parents participated. Findings indicate that, despite differences in context, including the child's condition and age, end-of-life decision-making did not end when an end-of-life decision was made. Enacting the decision was the next stage in a process. Time intervals between stages and enactment pathways varied, but the enactment was always distinguishable as a separate stage. Decision enactment involved making further decisions - parents needed to discern the appropriate time to implement their decision to withdraw or withhold life-sustaining medical treatment. Unexpected events, including other people's actions, impacted on parents enacting their decision in the way they had planned. Several parents had to re-implement decisions when their child recovered from serious health issues without medical intervention. Significance of results A novel, critical finding was that parents experienced end-of-life decision-making as a sequence of interconnected stages, the final stage being enactment. The enactment stage involved further decision-making. End-of-life decision-making is better understood as a process rather than a discrete once-off event. The enactment stage has particular

    We aimed to clarify the relationships of the different stages of behavior change in dietary habits followed by the mothers of school-age children with the actual breakfast intake of these children and the health-associated behavior of the family. We carried out a questionnaire-based survey of 1949 children at 18 elementary schools and of 881 families with children attending seven elementary schools in Kagoshima prefecture. We were supplied with information about children's breakfast intake and content on the day they took the survey and information about mothers' breakfast intake and the stage of behavior change in dietary habits to which they belonged, for which five stages were defined using the stage-of-change model. The collection rates were 83.3% and 83.1% among children and mothers respectively. Of the children, 83.1% ate breakfast every day, while 15.1% were not in the habit of having breakfast. Furthermore, 98.6% children had eaten breakfast on the day of the survey, but 15.1% had eaten only staple foods such as rice or bread; only 34.0% children combined staple foods, a main dish, and vegetables/fruits in their breakfast. Regarding dietary stage, 28.1% of the mothers belonged to the "maintenance" stage; 24.0%, the "action" stage; 6.9%, the "preparation" stage; 9.8%, the "contemplation" stage; and 5.7%, the "precontemplation" stage. Mothers belonging to the first two stages constituted the "action group," because they were already taking care of their dietary habits, and mothers belonging to the latter three stages constituted the "no-action group", because they were not taking care of their dietary habits. The mothers who could provide no answers to the question constituted the "no-answer group" (25.5%). A comparison of the three groups revealed that mothers belonging to the no-answer group had more children who went without breakfast than the action group (P = 0.000). The children of mothers belonging to the no-action group (P = 0.003) and the no

    Full Text Available Abstract Background Prognostic factors in locally advanced breast cancer treated with neoadjuvant chemotherapy differ from those of early breast cancer. The purpose of this study was to identify the clinical significance of potential predictive and prognostic factors in breast cancer patients treated by neoadjuvant chemotherapy. Methods A total of 145 stage II and III breast cancer patients received neoadjuvant docetaxel/doxorubicin chemotherapy were enrolled in this study. We examined the clinical and biological factors (ER, PR, p53, c-erbB2, bcl-2, and Ki-67 by immunohistochemistry. We analyzed clinical outcome and their correlation with clinicopathologic parameters. Results Among the clinicopathologic parameters investigated, none of the marker was correlated with response rate (RR except triple negative phenotype. Patients with triple negative phenotype showed higher RR (83.0% in triple negative vs. 62.2% in non-triple negative, p = 0.012 and pathologic complete RR (17.0% in triple negative vs. 3.1% in non-triple negative, p = 0.005. However, relapse free survival (RFS and overall survival (OS were significantly shorter in triple negative breast cancer patients (p p = 0.021, respectively. Low histologic grade, positive hormone receptors, positive bcl-2 and low level of Ki-67 were associated with prolonged RFS. In addition, positive ER and positive bcl-2 were associated with prolonged OS. In our homogeneous patient population, initial clinical stage reflects RFS and OS more precisely than pathologic stage. In multivariate analysis, initial clinical stage was the only significant independent prognostic factor to impact on OS (hazard ratio 3.597, p = 0.044. Conclusion Several molecular markers provided useful predictive and prognostic information in stage II and III breast cancer patients treated with neoadjuvant docetaxel/doxorubicin chemotherapy. Triple negative phenotype was associated with shorter survival, even though it was associated

    Annually, 5000 children younger than 20 years of age and 200 younger than two-years require treatment for chronic kidney disease (CKD). The objective was to estimate the incidence rate of infectious complications in children requiring renal replacement therapy. Retrospective cohort. Patients with a minimum of three months of follow-up in programs of peritoneal dialysis and hemodyalisis were included. The incidence rate for infections associated to replacement therapy was calculated. 67 patients were analysed. In 88 %, initial therapy for CKD was peritoneal dialysis. A total of 52 episodes of peritonitis occured, with an incidence rate of 0.63 episodes/patient-year. Thirty children (48 %) never had an episode of peritonits during the folow-up. At six months, 90 % of the children had the same peritoneal dialysis catheter, decreasing to 84, 74 and 50 % at 12, 18 and 24 months, respectively. Forty-five children were on hemodialysis, 82 % preceded by peritoneal dialysis. Dialysis treatment time in 25 % of them was longer than 19 months. Twenty-two episodes of catheter-related bacteremia occurred, with an incidence rate of 1 episode/1000 catheter-days or 2.5/1000 hemodyalisis sesions. Twenty-nine patients received a transplant (43 %); two of them died. Median waiting time to transplant was 15 months. Incidence rate of infectious complications was similar to the rates reported in the literature by other centers. At 20 months, half of the patients had at least one infectious complication.

    Purpose: Rituximab (Rit) therapy added to involved-field radiation therapy (RT) has been proposed as an effective treatment for stage I-II follicular lymphoma (FL). The results of an observational multicenter study on the Rit-RT combination in limited-stage FL are here reported. Methods and Materials: Data have been collected from 2 consecutive cohorts of 94 patients with stage I-II FL treated between 1985 and 2011 at 5 Italian institutions. All patients had grade 1-3a FL, a median age of 54 years (range: 25-82). The first 51 patients received RT alone (control group), while the subsequent series of 43 patients received 4 rituximab courses (375 mg/m{sup 2}, days 1, 8, 15, 22) before RT (Rit-RT). Molecular disease was evaluated by nested bcl-2/IgH PCR or clonal IgH rearrangement was available in 33 Rit-RT patients. Results: At a median follow-up of 10.9 years (range: 1.8-22.9), the 10-year progression-free survival (PFS) and overall survival (OS) projections for the whole cohort were 57% and 87.5%, respectively. The 10-year PFS was significantly longer (P<.05) in the Rit-RT group (64.6%) compared to RT alone (50.7%), whereas the 10-year OS projections were not significantly different. On bivariate analysis controlling for stage, there was only a trend toward improved PFS for Rit-RT (HR, 0.55; P=.081). Follicular lymphoma international prognostic index and age were associated with OS but not with PFS on Cox regression analysis. Bone marrow molecular analysis showing PCR positivity at diagnosis was strongly associated with relapse risk upon univariate and multivariate analysis. Conclusions: This multicenter observational study suggests a potential benefit of adding rituximab to radiation therapy for stage I-II FL. The results of the currently ongoing randomized studies are required to confirm these results. The study underlines the importance of molecular disease monitoring also for patient with limited-stage disease.

    To evaluate the side effects, pattern of failure, and survival rate according to the sequence of postoperative adjuvant radiotherapy and chemotherapy, patients with stages II and III rectal cancer who had undergone curative resection were randomized to early radiotherapy group(am II), then we intend to determine the most effective sequence of the radiotherapy and chemotherapy. From January 1996 to March 1999, 313 patients with curatively resected stages II and III rectal cancer have been randomized to 'early' or 'late' radiation therapy group and received combined chemotherapy (5-FU 375 mg/m{sup 2}, IV bolus daily D1-5, 8 cycles) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Arm I received radiation therapy from day 1 with first cycle of chemotherapy and arm II received radiation therapy from day 57 with third cycle of chemotherapy after completion of first two cycles. Preliminary analysis was performed with 228 patients registered up to Jun 1998. Two out of the 228 patients were excluded because of double primary cancer. Median follow-up period was 23 months. Local recurrence occurred in 11 patients (9.7%) for arm l and 9 patients (8%) for arm II. There was no significant difference between both groups (p=0.64). However, distant metastasis was found in 22 patients (19.5%) for arm l and 35 patients (31.0%) for arm II and which showed statistically significant difference between the two groups (p=0.046). And neither 3-year disease-free survival (70.2% vs 59.2%, p=0.2) nor overall survival (89.4% vs 88.0%, p=0.47) showed significant differences. The incidence of leukopenia during radiation therapy and chemotherapy was 78.3% and 79.9% respectively but leukopenia more than RTOG grade 3 was only 2.1% and 6.0% respectively. The incidence of diarrhea more than 10 times per day was significantly higher in the patients for arm k than for arm II (71.2% vs 41.6%, p=0.02) but this complication was controlled with supportive cares

    Full Text Available Introduction: This is an empirical article aiming at defining the changes of motor fitness in children practicing swimming at early stage of training in year-long training cycle. Proper selection of candidates to practice certain sports is a very complex process. One needs to select from the very large population of children, girls and boys, characterized by certain features, including somatic and motor features, which developed in a longstanding process of training, will lead them to become champions. The purpose of the research: The purpose of the research was to define the changes of motor fitness in girls’ practicing swimming at early stage of training in year-long training cycle. Material and Methods: The subjects to the research were 85 girls aged 7 (1st year of primary school, including 36 girls in swimming group and 49 girls in control group. 36 of them belonged to swimmers’ group- all girls were members of the Municipal Swimming Club in Szczecin. Control group consisted of 49 girls, who attended the same elementary schools. The examinations were carried out twice in the 2009-2010 academic year. The most reliable and accurate indirect test- EUROFIT Test Battery-was used. Results : The research revealed changes in both groups (Sw, C in terms of all eight tests. Examination II proved statistically significant improvement of results in both groups (Sw, C in comparison to Examination I. The dynamics of changes in general balance, flexibility, static force, functional force, running agility, was bigger in the girls who practiced swimming. As the speed of movement of upper limb, explosive force and thorax force are concerned; the differences of results in both examinations were similar in both groups (swimming group and control group. Progressive changes in motor fitness of the examined groups are a positive phenomenon in the development of child’s young organism. Conclusions: Swimming training significantly affected the dynamics of

The aim was to analyze the complication rates and uroflow data of boys who have previously undergone a two-stage graft urethroplasty procedure for proximal and complicated hypospadias. We retrospectively reviewed the clinical outcomes of 52 boys with proximal (n = 44) and complicated (n = 8) hypospadias who underwent two-stage graft urethroplasty repair (median age of 15 months and 3 years respectively) between 2004 and 2015. Fifteen toilet-trained boys without fistulas underwent uroflowmetry. The uroflow data were plotted on age-volume-dependent normograms with normal controls. The median follow-up was 34 months (8 months-8 years). Complications were identified in three patients (6%) after the first stage (i.e. contracture of the graft) and in 20 patients (38.4%) after the second stage, including meatal stenosis (n = 8, 15.3%), urethral stricture (n = 4, 7.6%), urethrocutaneous fistula (n = 8, 15.3%), glandular dehiscence (n = 1, 1.9%), and diverticulum (n = 1, 1.9%). The patients with failed hypospadias experienced fewer complications than those who underwent the two-stage procedure for primary repair (25% and 45%, respectively). The reoperation rate was 36.8%. Eleven of the 15 toilet-trained boys were asymptomatic but exhibited flow rates below the normal range (median Q max  = 7 mL/s, range 3.5-16.7). Only one of the boys with a low flow rate was confirmed to have urethral stenosis under general anesthesia. In our study, primary hypospadias repair requiring urethral plate transection elicited worse outcomes than those observed in the prior failed hypospadias cases. However, because of our study's retrospective design, we were unable to accurately assess the initial position of the meatus in the redo hypospadias cases. Our data also demonstrated that the majority

    To evaluate FDG-PET for staging, grading, preoperative response assessment and posttherapeutic evaluation in children with Wilms tumour (WT). In this study, 23 FDG-PET examinations in 12 paediatric patients (female, n=5; male, n=7; age, 1-19 years) with WT (primary, n=9; relapsed, n=3) were analysed. All patients were examined with conventional imaging methods (CIM) according to the SIOP2001/GPOH trial protocol. Additionally, FDG-PET/PET-CT was performed for staging (n = 12), preoperative response assessment (n=6) and posttherapeutic evaluation (n=5). Imaging results of FDG-PET and CIM were analysed regarding the accuracy in tumour visualisation, impact on therapeutic management and preoperative response assessment, with clinical follow-up and histopathology as the standard of reference. FDG-PET and CIM showed concordant results for staging of primary WT, whereas FDG-PET was superior in 1/3 cases with recurrent WT. Concerning histological differentiation, one case with anaplastic WT had an standard uptake value (SUV) of 12.3, which was remarkably higher than the average SUV in the eight cases with intermediate risk histology. No parameter analysed for PET or CIM was reliably predictive for histological regression or clinical outcome. After completion of therapy, FDG-PET was superior to CIM in 2/5 cases in detecting residual disease with therapeutic relevance. FDG-PET does not provide additional information to the traditional imaging work-up for staging WT patients, preoperative response assessment and clinical outcome. FDG-PET was advantageous in ruling out residual disease after completion of first line treatment and in pretherapeutic staging of relapse patients. Furthermore, there seems to be a good correlation of initial SUV and histological differentiation. (orig.)

  20. Advantages of adjuvant chemotherapy for patients with triple-negative breast cancer at Stage II: usefulness of prognostic markers E-cadherin and Ki67

    Science.gov (United States)

    2011-01-01

    Introduction Triple-negative breast cancer (TNBC), which is characterized by negativity for estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2 (HER2), is a high risk breast cancer that lacks specific targets for treatment selection. Chemotherapy is, therefore, the primary systemic modality used in the treatment of this disease, but reliable parameters to predict the chemosensitivity of TNBC have not been clinically available. Methods A total of 190 TNBC patients who had undergone a curative resection of a primary breast cancer were enrolled. The adjuvant chemotherapy was performed for 138 (73%) of 190 TNBC cases; 60 cases had an anthracyclin-based regimen and 78 a 5-fluorouracil-based regimen. The prognostic value of E-cadherin, Ki67 and p53 expression in the outcome of TNBC patients with adjuvant chemotherapy was evaluated by immunohistochemistry. Results The adjuvant therapy group, especially those with Stage II TNBC, had a more favorable prognosis than the surgery only group (P = 0.0043), while there was no significant difference in prognosis between the anthracyclin-based regimen and 5-fluorouracil-based regimen. Patients with E-cadherin-negative and Ki67-positive expression showed significantly worse overall survival time than those with either E-cadherin-positive or Ki67-negative expression (P Ki67-positive expression was strongly predictive of poor overall survival (P = 0.004) in TNBC patients receiving adjuvant chemotherapy. In contrast, p53 status was not a specific prognostic factor. Conclusions Adjuvant therapy is beneficial for Stage II TNBC patients. The combination of E-cadherin and Ki67 status might be a useful prognostic marker indicating the need for adjuvant chemotherapy in Stage II TNBC patients. PMID:22126395

    Full Text Available BACKGROUND: To evaluate the prognostic value of E-cadherin, CD44, and MSH2 expression for colorectal cancer (CRC and construct nomograms that can predict prognosis. METHODS: We retrospectively analyzed the expression of E-cadherin, CD44, and MSH2 in 223 paraffin-embedded stage II and III CRC specimens using immunohistochemistry in the training cohort. Their prognostic values were assessed using Kaplan–Meier curves and univariate and multivariate COX regression models. Moreover, a number of risk factors were used to form nomograms to evaluate survival, and Harrell's concordance index (C-index was used to evaluate the predictive accuracy. Further validation of the nomograms was performed in an independent cohort of 115 cases. RESULTS: Low E-cadherin expression and low CD44 expression were significantly associated with diminished overall survival (OS and disease-free survival (DFS in stage II and III CRC patients and patients with negative MSH2 expression had better clinical outcomes. Moreover, the multivariate COX analysis identified E-cadherin, CD44 and MSH2 expression as independent prognostic factors for DFS and OS. Using these three markers and three clinicopathological risk variables, two nomograms were constructed and externally validated for predicting OS and DFS (C-index: training cohort, 0.779 (95% CI 0.722–0.835 and 0.771 (0.720–0.822, respectively; validation cohort, 0.773 (0.709–0.837 and 0.670 (0.594–0.747, respectively. CONCLUSION: The expression levels of E-cadherin, CD44 and MSH2 were independent prognostic factors for stage II and III CRC patients. By incorporating clinicopathological features and these biomarkers, we have established two nomograms that could be used to make individualized predictions for OS and DFS.

    This study was aimed at identifying prognostic biomarkers for stage II-IIIA non-small cell lung cancer (NSCLC) according to histology and at investigating the effect of vorinostat on the expression of these biomarkers. Expression levels of cyclin D1, cyclin A2, cyclin E, and p16 proteins that are involved in the G1-to-S phase progression of cell cycle were analyzed using immunohistochemistry in formalin-fixed paraffin-embedded tissues from 372 samples of stage II-IIIA NSCLC. The effect of vorinostat on the expression of these proteins, impacts on cell cycle, and histone modification was explored in lung cancer cells. Abnormal expression of cyclin A2, cyclin D1, cyclin E, and p16 was found in 66, 47, 34, and 51 % of 372 cases, respectively. Amongst the four proteins, only cyclin D1 overexpression was significantly associated with poor recurrence-free survival (adjusted hazard ratio = 1.87; 95 % confidence interval = 1.12 - 2.69, P = 0.02) in adenocarcinoma but not in squamous cell carcinoma (P = 0.44). Vorinostat inhibited cell cycle progression to the S-phase and induced down-regulation of cyclin D1 in vitro. The down-regulation of cyclin D1 by vorinostat was comparable to a siRNA-mediated knockdown of cyclin D1 in A549 cells, but vorinostat in the presence of benzo[a]pyrene showed a differential effect in different lung cancer cell lines. Cyclin D1 down-regulation by vorinostat was associated with the accumulation of dimethyl-H3K9 at the promoter of the gene. The present study suggests that cyclin D1 may be an independent prognostic factor for recurrence-free survival in stage II-IIIA adenocarcinoma of lung and its expression may be modulated by vorinostat.

    The usefulness of the developmental status of the third molar has been studied in assessment of the chronological age of adolescents in whom the development of the other permanent teeth is nearly complete. However, little is known about the timing and pattern of third-molar development in the Indian population. This study aimed to stage the third molar development in relation to chronological age of 5-16year old Indian children. In this cross-sectional observational study, the status of third molar development in relation to chronological age of 1139 Indian children aged 5-16 years was evaluated radiographically, using Orhan's modification of Demirjian's method. The frequency of occurrence of the third molars varied from 47% to 70%. Crypt formation, crown completion and root completion occurred as early as 5.4, 8.7 and 15.0 years, respectively. No significant differences based on gender or side were observed in third-molar development (p>0.05). For most stages, maxillary third molars were slightly more advanced than their mandibular counterparts (p>0.05). Considering the high degree of variability observed in third molar genesis and development, the usefulness of this tooth in age determination studies may be very limited in the age group studied.

    To prospectively study the value of PET-CT with fluorine-18 fluorodeoxyglucose (FDG) to predict neoadjuvant chemotherapy (NAC) response of locoregional disease of stages II and III breast cancer patients. A written informed consent and approval were obtained from the Ethics Committee. PET-CT accuracy in the prediction of pathologic complete response (pCR) after NAC was studied in primary tumors and lymph node metastasis in 43 women (mean age: 50 years: range: 27-71 years) with histologically proven breast cancer between December 2009 and January 2011. PET-CT was performed at baseline and after NAC. SUV(max) percentage changes (ΔSUV(max)) were compared with pathology findings at surgery. Receiver-operator characteristic (ROC) analysis was used to discriminate between locoregional pCR and non-pCR. In patients not achieving pCR, it was investigated if ΔSUV(max) could accurately identify the residual cancer burden (RCB) classes: RCB-I (minimal residual disease (MRD)), RCB-II (moderate RD), and RCB-III (extensive RD). pCR was obtained in 11 patients (25.6%). Residual disease was found in 32 patients (74.4%): 16 (37.2%) RCB-I, 15 (35.6%) RCB-II and 2 (4.7%) RCB-III. Sensitivity, specificity, and accuracy to predict pCR were 90.9%, 90.6%, and 90.7%, respectively. Specificity was 94.1% in the identification of a subset of patients who had either pCR or MRD. Accuracy of ΔSUV(max) in the locoregional disease of stages II and III breast cancer patients after NAC is high for the identification of pCR cases. Its specificity is potentially sufficient to identify a subgroup of patients who could be managed with conservative surgery. Copyright © 2013 Elsevier España, S.L. and SEMNIM. All rights reserved.

    Full Text Available Background and objective Increased macrophage inhibitory cytokine-1 (MIC-1, member of transforming growth factor-β (TGF-β superfamily, was found in patients serum with epithelial tumors. Therefore, our aim was to delineate the diagnostic and prognostic value of serum MIC-1 in patients with stage I-II non-small cell lung cancer (NSCLC. Methods A total of 152 consecutive patients with stage I–II NSCLC were prospectively enrolled and underwent follow up after total resection of tumor. Serum MIC-1 level was detected in lung cancer patients by ELISA, 48 benign pulmonary disease patients and 105 healthy controls, and was correlated with clinical features and prognosis of patients. Results The level of MIC-1 of NSCLC patients was significantly higher than that of controls (P<0.001 and benign pulmonary disease patients (P<0.001. A threshold of 1,000 pg/mL could be used to diagnose early-stage NSCLC with 70.4% sensitivity and 99.0% specificity. The level of MIC-1 was associated with elder age (P=0.001, female (P=0.03 and T2 (P=0.022. A threshold of 1,465 pg/mL could identify patients with early poor outcome with 72.2% sensitivity and 66.1% specificity. The overall 3-year survival rate in patients with high level of MIC-1 (≥1,465 pg/mL was significantly lower than that of patients with low MIC-1 level (77.6% vs 94.8%. Multivariable Cox regression revealed that a high level of MIC-1 was an independent risk factor for compromised overall survival (HR=3.37, 95%CI: 1.09-10.42, P=0.035. Conclusion High level of serum MIC-1 could be served as a potential biomarker for diagnosis and poorer outcome in patients with early-stage NSCLC.

    Background: The role of surveillance studies in limited-stage diffuse large B-cell lymphoma (DLBCL) in the rituximab era has not been well defined. We sought to evaluate the use of imaging (computed tomography [CT] and positron emission tomography [PET]-CT) scans and lactate dehydrogenase (LDH) in surveillance of patients with stage I to II DLBCL. Methods: A retrospective analysis was performed of patients who received definitive treatment between 2000 and 2013. Results: One hundred sixty-two consecutive patients with stage I to II DLBCL were treated with chemotherapy +/− rituximab, radiation, or combined modality therapy. The 5-year rates of overall survival (OS) and freedom from progression (FFP) were 81.2% and 80.8%, respectively. Of the 162 patients, 124 (77%) were followed up with at least 1 surveillance PET scan beyond end-of-treatment scans; of those, 94 of 124 (76%) achieved a complete metabolic response on PET scan after completion of chemotherapy, and this was associated with superior FFP (P=.01, HR=0.3) and OS (P=.01, HR 0.3). Eighteen patients experienced relapse after initial response to therapy. Nine relapses were initially suspected by surveillance imaging studies (8 PET, 1 CT), and 9 were suspected clinically (5 by patient-reported symptoms and 4 by symptoms and physical examination). No relapses were detected by surveillance LDH. The median duration from initiation of treatment to relapse was 14.3 months among patients with relapses suspected by imaging, and 59.8 months among patients with relapses suspected clinically (P=.077). There was no significant difference in OS from date of first therapy or OS after relapse between patients whose relapse was suspected by imaging versus clinically. Thirteen of 18 patients underwent successful salvage therapy after relapse. Conclusions: A complete response on PET scan immediately after initial chemotherapy is associated with superior FFP and OS in stage I to II DLBCL. The use of PET scans as

    Purpose: Mantle cell lymphoma (MCL) is a rare, albeit aggressive subset of non-Hodgkin lymphoma, resulting in varied treatment approaches. Given the paucity of data defining the optimal management for early-stage MCL, we conducted an analysis using the National Cancer Data Base (NCDB) to identify practice patterns and outcomes. Methods and Materials: The NCDB was queried for patients with stage I to II MCL diagnosed from 1998 to 2012 receiving chemotherapy (CT) or radiation therapy (RT), or both (CT+RT). Univariate and multivariable analyses for factors associated with treatment selection were completed using logistic regression. Propensity scores with inverse probability treatment weighting (IPTW) were calculated based on the conditional probability of receiving CT+RT. The log-rank test and Cox proportional hazards modeling with IPTW adjustment were conducted for the survival analyses. Results: In total, 2539 patients were identified. The key characteristics were as follows: 69% were male, 71% were aged ≥60 years, 28% had extranodal involvement, and 51% had stage I disease. Of the 2539 patients, 70% underwent CT, 11% underwent RT, and 19% underwent CT+RT. The use of CT+RT decreased from 23.1% to 14.1% in 1998 to 2002 and 2010 to 2012 (P<.001). CT+RT usage was lower for patients with the following characteristics: age ≥60 years, female sex, stage II disease, and the presence of B symptoms. With a median follow-up period of 42.8 months, the unadjusted 3-year overall survival estimates for patients receiving CT, RT, or CT+RT were 67.8%, 72.4%, and 79.8%, respectively (P<.001). After correcting for indication bias through IPTW-adjusted modeling, CT+RT reduced the risk of overall mortality compared with monotherapy (hazard ratio 0.65, P=.029). Conclusions: Although uncommon, patients with stage I-II MCL can have favorable outcomes. Despite a continued decline in the usage of consolidative RT, combined modality therapy improves survival in this cohort compared

    Purpose: Congenital portosystemic shunts (CPSS) with portal venous hypoplasia cause hyperammonemia. Acute shunt closure results in portal hypertension. A transcatheter method of staged shunt reduction to afford growth of portal vessels followed by shunt closure is reported. Methods: Pressure measurements and angiography in the CPSS or superior mesenteric artery (SMA) during temporary occlusion of the shunt were performed. If vessels were diminutive and the pressure was above 18 mmHg, a staged approach was performed, which included implantation of a tailored reducing stent to reduce shunt diameter by {approx}50 %. Recatheterization was performed approximately 3 months later. If the portal pressure was below 18 mmHg and vessels had developed, the shunt was closed with a device. Results: Six patients (5 boys, 1 girl) with a median age of 3.3 (range 0.5-13) years had CPSS portal venous hypoplasia and hyperammonemia. Five patients underwent staged closure. One patient tolerated acute closure. One patient required surgical shunt banding because a reducing stent could not be positioned. At median follow-up of 3.8 (range 2.2-8.4) years, a total of 21 procedures (20 transcatheter, 1 surgical) were performed. In all patients, the shunt was closed with a significant reduction in portal pressure (27.7 {+-} 11.3 to 10.8 {+-} 1.8 mmHg; p = 0.016), significant growth of the portal vessels (0.8 {+-} 0.5 to 4.0 {+-} 2.4 mm; p = 0.037), and normalization of ammonia levels (202.1 {+-} 53.6 to 65.7 {+-} 9.6 {mu}mol/L; p = 0.002) with no complications. Conclusion: Staged CPSS closure is effective in causing portal vessel growth and treating hyperammonemia.

    The RADLAC II Self Magnetically Insulated Transmission LinE ''SMILE'' is a coaxial wave guide structure that is composed of two regions: (a) a 9.5-m voltage adder and (b) a 3-m long extension section. The adder section provides for the addition of the input voltages from the individual water-dielectric pulse forming line feeds. The extension section isolates the adder from the magnetically immersed foilless diode electron source load and efficiently transports the pulsed power out from the deionized water tank of the device. The SMILE modification of the RADLAC II accelerator enabled us to produce high quality beams of up to 14 MV, 100 kA. The design and the experimental evaluation of SMILE will be presented and compared with numerical simulation predictions. 12 refs., 9 figs., 1 tab

The adder section provides for the addition of the input voltages from the individual water-dielectric pulse forming line feeds. The extension section isolates the adder from the magnetically immersed foilless diode electron source load and efficiently transports the pulsed power out from the deionized water tank of the device. The SMILE modification of the RADLAC II accelerator enabled us to produce high quality beams of up to 14 MV, 100 kA. The design and the experimental evaluation of SMILE will be presented and compared with numerical simulation predictions. 12 refs., 9 figs., 1 tab.

    This study investigated the growth trajectories and the relative relevance levels of nutrition, disease, and hormonal status at various developmental stages among children in adverse environments to provide population-based empirical evidence for the life history theory. Three years of longitudinal anthropometric data in 1-year intervals were obtained from 418 boys and girls aged 0 to 12 years at recruitment. Following the final measurement, the main survey, which included blood and feces sampling, 3-h interval food consumption recall surveys for energy and nutrient intakes and anthropometry, was performed. Blood and feces were used for detecting, respectively, anemia and hormonal (IGF-I and IGFBP-3) levels as well as intestinal helminthiasis (Ascaris, Trichuris, and hookworm). The major findings of this study are summarized as follows: 1) the growth velocity of the subject children lagged behind international standards during childhood and juvenility but caught up during early adolescence; 2) diseases, both intestinal helminths and anemia, had significant effects on growth in childhood but not at older ages; and 3) hormonal status significantly affected growth in the children, with its highest significance in early adolescence. A larger growth than international standards in early adolescence likely follows programmed hormonal mechanisms after the onset of puberty. The onset of puberty might be associated with adequate amounts of nutrient intake and be mediated by hormonal function, because the IGF-IZ score was significantly correlated with energy and protein intakes at the transitional period from juvenility to adolescence, when puberty occurs. © 2015 Wiley Periodicals, Inc.

    The efficacy of postoperative radiotherapy (PORT) for thymic epithelial tumors is still controversial. Using the Japanese Association for Research on the Thymus (JART) database, this study was aimed at clarifying the efficacy of PORT for Masaoka stage II and III thymic carcinoma and thymoma. The JART database registered the records of 2835 patients collected from 32 Japanese institutions from 1991 to 2010. Thymic carcinoma and thymoma at stage II or III were extracted. The efficacy of PORT with respect to relapse-free survival (RFS) and overall survival (OS) was evaluated with the Kaplan-Meier method and Cox regression analysis. There were 1265 patients in all: 155 thymic carcinoma cases (12.3%) and 1110 thymoma cases (87.7%). Eight hundred ninety-five (70.8%) were at stage II, and 370 (29.2%) were at stage III. Four hundred three cases (31.9%) underwent PORT. PORT for stage II and III thymic carcinoma was associated with increasing RFS (hazard ratio, 0.48; 95% confidence interval, 0.30-0.78; P = .003) but was not associated with OS (hazard ratio, 0.94; 95% confidence interval, 0.51-1.75; P = .536). PORT for stage II and III thymoma was not associated with RFS or OS (P = .350). A subgroup analysis of stage III thymoma showed no factor associated with the efficacy of PORT. In this study, PORT did not increase RFS or OS for stage II or III thymoma but increased RFS for stage II and III thymic carcinoma. © 2015 American Cancer Society.

    Background: Primary mediastinal B cell lymphoma (PMBCL) is an uncommon lymphoma for which trials are few with small patient numbers. The role of radiation therapy (RT) after standard immunochemotherapy for early-stage disease has never been studied prospectively. We used the Surveillance, Epidemiology, and End Results (SEER) database to evaluate PMBCL and the impact of RT on outcomes. Methods and Materials: We queried the SEER database for patients with stage I-II PMBCL diagnosed from 2001 to 2011. Retrievable data included age, gender, race (white/nonwhite), stage, extranodal disease, year of diagnosis, and use of RT as a component of definitive therapy. Kaplan-Meier overall survival (OS) estimates, univariate (UVA) log-rank and multivariate (MVA) Cox proportional hazards regression analyses were performed. Results: Two hundred fifty patients with stage I-II disease were identified, with a median follow-up time of 39 months (range, 3-125 months). The median age was 36 years (range, 18-89 years); 61% were female; 76% were white; 45% had stage I disease, 60% had extranodal disease, and 55% were given RT. The 5-year OS for the entire cohort was 86%. On UVA, OS was improved with RT (hazard ratio [HR] 0.446, P=.029) and decreased in association with nonwhite race (HR 2.70, P=.006). The 5-year OS was 79% (no RT) and 90% (RT). On MVA, white race and RT remained significantly associated with improved OS (P=.007 and .018, respectively). The use of RT decreased over time: 61% for the 67 patients whose disease was diagnosed from 2001 to 2005 and 53% in the 138 patients treated from 2006 to 2010. Conclusion: This retrospective population-based analysis is the largest PMBCL dataset to date and demonstrates a significant survival benefit associated with RT. Nearly half of patients treated in the United States do not receive RT, and its use appears to be declining. In the absence of phase 3 data, the use of RT should be strongly considered for its survival benefit in early-stage

    Diagnostic markers for recurrence of colorectal cancer have not been established. The aim of the present study was to identify new diagnostic markers for recurrence after curative surgery of stage II colon cancer. In this study, the prognostic values of the preoperative lymphocyte count and the post/preoperative lymphocyte count ratio (PPLR) were evaluated in 142 patients with localized colon cancer treated with surgery at a single medical center. The associations of patient demographics, blood chemistry, and serum biochemical indices with recurrence-free survival (RFS) and cancer-specific survival (CSS) were examined by univariate and multivariate analyses. Receiver operating characteristic (ROC) curve analysis showed that the optimal cut-off values of the lymphocyte count and PPLR were, respectively, 1555.2/μl and 1.151 for RFS. On univariate analysis, tumor depth of invasion, carbohydrate antigen 19-9 (CA19-9), and preoperative low lymphocyte count (≤1555.2/μl) were all correlated with poorer RFS ( p preoperative lymphocyte count high/low and PPLR high/low. Patients with a low preoperative lymphocyte count and low PPLR had the poorest RFS and CSS compared to the other patients. The combination of the preoperative lymphocyte count and the PPLR appears to be a potential marker for predicting recurrence of stage II colon cancer.

    This study aimed to assess prospectively the efficacy of sequential [18F]fluorodeoxyglucose positron emission tomography (FDG PET) to evaluate early response to neoadjuvant chemotherapy in stage II and III breast cancer patients. Images were acquired with a PET/computed tomography scanner in 64 patients after administration of FDG (5 MBq/kg) at baseline and after the first, second, third, and sixth course of chemotherapy. Ultrasound and mammography were used to assess tumor size. Decrease in the standardized uptake value (SUV) with PET was compared with the pathologic response. Surgery was performed after six courses of chemotherapy and pathologic analysis revealed gross residual disease in 28 patients and minimal residual disease in 36 patients. Although SUV data did not vary much in nonresponders (based on pathology findings), they decreased markedly to background levels in 94% (34 of 36) of responders. When using 60% of SUV at baseline as the cutoff value, the sensitivity, specificity, and negative predictive value of FDG PET were 61%, 96%, and 68% after one course of chemotherapy, 89%, 95%, and 85% after two courses, and 88%, 73%, and 83% after three courses, respectively. The same parameters with ultrasound (US) and mammography were 64%, 43%, and 55%, and 31%, 56%, and 45%, respectively. Assessment of tumor response with US or mammography was never significant whatever the cutoff. Pathologic response to neoadjuvant chemotherapy in stage II and III breast cancer can be predicted accurately by FDG PET after two courses of chemotherapy.

    The prognosis of patients with non-small cell lung cancer (NSCLC) is important, as patients with resectable disease and poor prognostic variables might benefit from neoadjuvant therapy. The goal of this study is to evaluate SUVmax, SUVmax ratio, CT volume (CTvol), metabolic tumour volume (MTV) and total lesion glycolisis (TLG) as survival prognostic markers. In addition, we defined two variables; MTV x SUVmax (MTVmax) and CTvol x SUVmax (CTvolmax) and assessed whether they can be used as prognostic markers. Patients with stage I-II NSCLC who underwent 18 F FDG PET/CT and surgery were evaluated. Cox proportional-hazard model was used to determine the association between variables and survival. Similar analysis was performed in cases with no lymph node (LN) involvement. One hundred and eighty-one patients were included (at the end of the study, 140 patients were alive). SUVmax with a cut-off value of 8.2 was significant survival prognostic factor regardless of LN involvement (P = 0.012). In cases with no LN involvement, SUVmax and CTvol (≥7.1 ml) were significant survival prognostic factors with P = 0.004 and 0.03, respectively. SUVmax may be a useful prognostic variable in stage I-II NSCLC while morphologic tumour volume might be useful in cases with no lymph node involvement. (orig.)

    Several studies suggest that general exercise (GE) and physical therapy programmes (PT) improve the outcomes of Parkinson's disease (PD) patients; however, the available data do not allow a determination of which treatment is more effective. Our study aims to compare the effects of physiotherapy and general exercise in Parkinson's disease. Design and setting: Randomized controlled trial -general hospital outpatient clinic. The participants were patients with Hoehn Yahr stage II PD. Two randomized groups: one receiving PT and one receiving GE. The outcome measures were the FIM, Hamilton Rating Scale, TUG test, and UPDRS. FIM median scores improved by 3 points in the PT group after treatment, and the improvements were maintained at follow-up. The GE FIM median scores were unchanged after treatment and were reduced by 1 point at follow-up (p < 0.05). The TUG test time was reduced in the PT group but increased in the GE group with a 3-second difference between groups at follow-up, suggesting improved functional mobility after specific physiotherapy (p < 0.05). The UPDRS median score change from baseline was significantly different between the two groups at the end of treatment (6.5 points) and at follow-up (11 points), with a benefit for the physiotherapy group. Physiotherapy seems to be more effective than a generic exercise programme in patients with Hoehn Yahr stage II PD.

  2. A two-stage design for phase II trials with time-to-event endpoint using restricted follow-up

    Full Text Available In phase II oncology trials, the use of new cytostatic drugs raises some questions regarding the endpoint. Time-to-event endpoints such as Progression-Free Survival have been recommended and led to new designs. In 2003, Case and Morgan proposed a design based on the comparison of the cumulative hazards at a clinically relevant timepoint. In 2013, Kwak proposed a design based on the one-sample log-rank test. If all the patients are followed from their entry time to the analysis date, the Kwak and Jung’s design leads to a smaller sample size as compared to the Case-Morgan’s design. However, the Case and Morgan’s design requires less information since it only needs to follow every patient during a fixed interval of time. We propose a trade-off between these two approaches that corresponds to an adaptation of Kwak and Jung’s design when the follow-up is expected to be restricted. Our proposal is based on the one-sample log-rank test as the Kwak and Jung’s design but it uses the same follow-up information as the Case-Morgan’s design. Simulation study shows that our proposal allows reducing the sample size as compared to the Case-Morgan’s design (median difference of 23% [15%-33%]. Type I and type II error rates are close to their nominal rates planned in the protocol. A real phase II clinical trial in cervical cancer illustrated the interest of this new design. Thus, our proposal can be recommended as an alternative to the Kwak’s design when patients’ follow-up is restricted.

    The aim of this study was to evaluate the association of serum intact fibroblast growth factor 23 (FGF23) concentrations with indexed left ventricular mass in children with non-dialysis stages 3-5 of chronic kidney disease (CKD). The study cohort comprised 83 children (51 boys; mean age 12.1 ± 3.2 years) with a mean estimated glomerular filtration rate (eGFR) of 32.3 ± 14.6 ml/min/1.73 m(2) who underwent clinic and ambulatory blood pressure measurement (ABPM), echocardiography and evaluation of biochemical markers of CKD-associated mineral bone disease. The mean left ventricular mass index (LVMI) was 35.9 ± 8.5 g/m(2.7) (± standard deviation), with 30 (36.1 %) children showing left ventricular hypertrophy (LVH), all eccentric, as defined using age-specific criteria. For all subjects, the mean FGF23 concentration was 142.2 ± 204.4 ng/l and the normalised distribution following log transformation was 1.94 ± 0.39. There was significant univariate correlation of LVMI with GFR, body mass index (BMI) z-score and calcium intake, but not with 24-h systolic ABPM z-score, log intact parathyroid hormone or log FGF23. On multivariate analysis following adjustment for confounders, only elemental calcium content (g/kg/day) estimated from prescribed calcium-based phosphate binder dose (β = 154.9, p children are needed to clarify the roles of calcium-containing phosphate binders and FGF23 with LV mass and their roles in the evolution of the development of adverse cardiovascular outcomes.

    Lipids are essential components of cell membranes, contributing to cell fuel, myelin formation, subcellular organelle function, and steroid hormone synthesis. Children with chronic kidney disease (CKD) and end-stage renal disease (ESRD) exhibit various co-morbidities, including dyslipidemia. The prevalence of dyslipidemias in children with CKD and ESRD is high, being present in 39-65% of patients. Elevated lipid levels in children without renal disease are a risk factor for cardiovascular disease (CVD), while the risk for CVD in pediatric CKD/ESRD is unclear. The pathogenesis of dyslipidemia in CKD features various factors, including increased levels of triglycerides, triglyceride-rich lipoproteins, apolipoprotein C3 (ApoC-III), decreased levels of cholesterylester transfer protein and high-density lipoproteins, and aberrations in serum very low-density and intermediate-density lipoproteins. If initial risk assessment indicates that a child with advanced CKD has 2 or more co-morbidities for CVD, first-line treatment should consist of non-pharmacologic management such as therapeutic lifestyle changes and dietary counseling. Pharmacologic treatment of dyslipidemia may reduce the incidence of CVD in children with CKD/ESRD, but randomized trials are lacking. Statins are the only class of lipid-lowering drugs currently approved by the U.S. Food and Drug Administration (FDA) for use in the pediatric population. FDA-approved pediatric labeling for these drugs is based on results from placebo-controlled trial results, showing 30-50% reductions in baseline low-density lipoprotein cholesterol. Although statins are generally well tolerated in adults, a spectrum of adverse events has been reported with their use in both the clinical trial and post-marketing settings.

    African American (AA) colon cancer patients have a worse prognosis than Caucasian (CA) colon cancer patients, however, reasons for this disparity are not well understood. To determine if tumor biology might contribute to differential prognosis, we measured recurrence risk and gene expression using the Oncotype DX® Colon Cancer Assay (12-gene assay) and compared the Recurrence Score results and gene expression profiles between AA patients and CA patients with stage II colon cancer. We retrieved demographic, clinical, and archived tumor tissues from stage II colon cancer patients at four institutions. The 12-gene assay and mismatch repair (MMR) status were performed by Genomic Health (Redwood City, California). Student's t-test and the Wilcoxon rank sum test were used to compare Recurrence Score data and gene expression data from AA and CA patients (SAS Enterprise Guide 5.1). Samples from 122 AA and 122 CA patients were analyzed. There were 118 women (63 AA, 55 CA) and 126 men (59 AA, 67 CA). Median age was 66 years for AA patients and 68 for CA patients. Age, gender, year of surgery, pathologic T-stage, tumor location, the number of lymph nodes examined, lymphovascular invasion, and MMR status were not significantly different between groups (p = 0.93). The mean Recurrence Score result for AA patients (27.9 ± 12.8) and CA patients (28.1 ± 11.8) was not significantly different and the proportions of patients with high Recurrence Score values (≥41) were similar between the groups (17/122 AA; 15/122 CA). None of the gene expression variables, either single genes or gene groups (cell cycle group, stromal group, BGN1, FAP, INHBA1, Ki67, MYBL2, cMYC and GADD45B), was significantly different between the racial groups. After controlling for clinical and pathologic covariates, the means and distributions of Recurrence Score results and gene expression profiles showed no statistically significant difference between patient groups.

    Early detection of cardiovascular disease in children with end-stage renal disease is essential in order to prevent cardiovascular morbidity and mortality in early adulthood. Tissue Doppler imaging has shown to be a promising method to detect and quantify subtle abnormalities in diastolic function. We therefore compared assessment of diastolic function by conventional echocardiography and tissue Doppler imaging. We performed conventional echocardiography and tissue Doppler imaging in 38 children with end-stage renal disease and 76 healthy controls. We compared outcomes on parameters related to diastolic function (E/a ratio for conventional echocardiography and E/E' ratio for tissue Doppler imaging) for both groups using multiple linear regression analysis. Diastolic dysfunction was defined as E/a ratio 95th percentile for age. To assess the intra-observer reproducibility, the coefficient of variation was calculated. Children with end-stage renal disease had on average a lower E/a ratio (p = 0.004) and a higher mitral and septal E/E' ratio (both p children with end-stage renal disease (5%) had diastolic dysfunction according to the E/a ratio, 11 according to the mitral E/E' ratio (29%), and 16 according to the septal E/E' ratio (42%) compared with none of the controls (p = 0.109, p children with end-stage renal disease.

    To illustrate the multidetector computed tomography (MDCT) findings in patients with end-stage biliary atresia (BA). The study group consists of 45 consecutive patients with BA who underwent MDCT before liver transplantation from February 2005 to February 2008. Mean age was 36 months, 24 patients were female, and 22 had undergone a previous Kasai procedure. MDCT detected a total of 15 hepatocellular nodules in 7 patients. Intrahepatic biliary cysts were detected in 14 patients and were significantly associated with a Kasai procedure. Intrahepatic porto-systemic shunts were found in 14 patients (31%), intrahepatic communicating vessels between hepatic veins were found in 24 patients (53%). Anatomical variants of hepatic artery were detected in 21 patients. Seven patients (15%) had portal vein thrombosis; in 12 cases (26%) portal vein diameter was 3 mm or less. MDCT can provide accurate morphological and vascular assessment of patients with end-stage biliary atresia and should be used for precise surgical planning. To the best of our knowledge this is one of the first studies to show the presence of numerous veno-venous communications in BA. (orig.)

    Purpose: Conventional radiation fractionation of 1.8-2 Gy per day for early stage breast cancer requires daily treatment for 6-7 weeks. We report the 5-year results of a phase II study of intensity modulated radiation therapy (IMRT), hypofractionation, and incorporated boost that shortened treatment time to 4 weeks. Methods and Materials: The study design was phase II with a planned accrual of 75 patients. Eligibility included patients aged {>=}18 years, Tis-T2, stage 0-II, and breast conservation. Photon IMRT and an incorporated boost was used, and the whole breast received 2.25 Gy per fraction for a total of 45 Gy, and the tumor bed received 2.8 Gy per fraction for a total of 56 Gy in 20 treatments over 4 weeks. Patients were followed every 6 months for 5 years. Results: Seventy-five patients were treated from December 2003 to November 2005. The median follow-up was 69 months. Median age was 52 years (range, 31-81). Median tumor size was 1.4 cm (range, 0.1-3.5). Eighty percent of tumors were node negative; 93% of patients had negative margins, and 7% of patients had close (>0 and <2 mm) margins; 76% of cancers were invasive ductal type: 15% were ductal carcinoma in situ, 5% were lobular, and 4% were other histology types. Twenty-nine percent of patients 29% had grade 3 carcinoma, and 20% of patients had extensive in situ carcinoma; 11% of patients received chemotherapy, 36% received endocrine therapy, 33% received both, and 20% received neither. There were 3 instances of local recurrence for a 5-year actuarial rate of 2.7%. Conclusions: This 4-week course of hypofractionated radiation with incorporated boost was associated with excellent local control, comparable to historical results of 6-7 weeks of conventional whole-breast fractionation with sequential boost.

    Several different approaches for restoring sight in subjects who are blind due to outer retinal degeneration are currently under investigation, including stem cell therapy, gene therapy, and visual prostheses. Although many different types of visual prostheses have shown promise, to date, the Argus II Epiretinal Prosthesis System, developed in a clinical setting over the course of 10 years, is the world's first and only retinal prosthesis that has been approved by the United States Food and Drug Administration (FDA) and has been given the CE-Mark for sale within the European Economic Area (EEA). The incidence of serious adverse events from Argus II implantation decreased over time after minor changes in the implant design and improvements in the surgical steps used for the procedure had been made. In order to further decrease the scleral incision-related complications and enhance the assessment of the tack position and the contact between the array and the inner macular surface, we used an ophthalmic endoscope during the regular course of Argus II implantation surgery in 2 patients with late-stage retinitis pigmentosa in an attempt to improve the anatomical and functional outcomes.

    Colorectal carcinoma (CRC) with CpG island methylator phenotype (CIMP) is recognized as a distinct subgroup of CRC, and CIMP status affects prognosis and response to chemotherapy. Identification of CIMP status in CRC is important for proper patient management. In Eastern countries, however, the clinicopathologic and molecular characteristics and prognosis of CRCs with CIMP are still unclear. A total of 245 patients who underwent their first surgical resection for sporadic CRC were enrolled and CIMP status of the CRCs was determined using the quantitative MethyLight assay. The clinicopathologic and molecular characteristics were reviewed and compared according to CIMP status. In addition, the three-year recurrence-free survival (RFS) of 124 patients with stage II or stage III CRC was analyzed in order to assess the effectiveness of fluoropyrimidine-based adjuvant chemotherapy with respect to CIMP status. CIMP-high CRCs were identified in 34 cases (13.9%), and were significantly associated with proximal tumor location, poorly differentiated carcinoma, mucinous histology, and high frequencies of BRAF mutation, MGMT methylation, and MSI-high compared to CIMP-low/negative carcinomas. For patients with stage II or III CIMP-low/negative CRCs, no significant difference was found in RFS between those undergoing surgery alone and those receiving surgery with fluoropyrimidine-based adjuvant chemotherapy. However, for patients with CIMP-high CRCs, patients undergoing surgery with fluoropyrimidine-based adjuvant chemotherapy (n = 17; three-year RFS: 100%) showed significantly better RFS than patients treated with surgery alone (n = 7; three-year RFS: 71.4%) (P = 0.022). Our results suggest that selected patients with CIMP-high CRC may benefit from fluoropyrimidine-based adjuvant chemotherapy with longer RFS. Further large scale-studies are required to confirm our results

    Preimaginal stages of the six species of Hydraenidae presently known from Cuba were obtained by rearing adults in the laboratory. Eggs of Hydraena perkinsi Spangler, 1980, H. decui Spangler, 1980 and H. franklyni Deler-Hernández & Delgado, 2012 are described and illustrated for the first time. The first instar larva of Gymnochthebius fossatus (LeConte, 1855) is redescribed, adding some new remarkable morphological characters including what could be the first abdominal egg-burster reported for this family. All larval instars of H. perkinsi, H. guadelupensis Orchymont, 1923 and Ochthebius attritus LeConte, 1878 are described and illustrated for the first time, with a special emphasis on their chaetotaxy. The second instar larva of G. fossatus along with first and third instar larvae of H. decui and H. franklyni are also studied for the first time. The pupal morphology and vestiture of a species belonging to the genus Hydraena are described for the first time, based on the pupa of H. perkinsi. Biological notes for several preimaginal stages of the studied species are also given.

    We aimed to describe survival in European pediatric dialysis patients and compare the differential mortality risk between patients starting on hemodialysis (HD) and peritoneal dialysis (PD). Data for 6473 patients under 19 years of age or younger were extracted from the European Society of Pediatric Nephrology, the European Renal Association, and European Dialysis and Transplant Association Registry for 36 countries for the years 2000 through 2013. Hazard ratios (HRs) were adjusted for age at start of dialysis, sex, primary renal disease, and country. A secondary analysis was performed on a propensity score-matched (PSM) cohort. The overall 5-year survival rate in European children starting on dialysis was 89.5% (95% confidence interval [CI] 87.7%-91.0%). The mortality rate was 28.0 deaths per 1000 patient years overall. This was highest (36.0/1000) during the first year of dialysis and in the 0- to 5-year age group (49.4/1000). Cardiovascular events (18.3%) and infections (17.0%) were the main causes of death. Children selected to start on HD had an increased mortality risk compared with those on PD (adjusted HR 1.39, 95% CI 1.06-1.82, PSM HR 1.46, 95% CI 1.06-2.00), especially during the first year of dialysis (HD/PD adjusted HR 1.70, 95% CI 1.22-2.38, PSM HR 1.79, 95% CI 1.20-2.66), when starting at older than 5 years of age (HD/PD: adjusted HR 1.58, 95% CI 1.03-2.43, PSM HR 1.87, 95% CI 1.17-2.98) and when children have been seen by a nephrologist for only a short time before starting dialysis (HD/PD adjusted HR 6.55, 95% CI 2.35-18.28, PSM HR 2.93, 95% CI 1.04-8.23). Because unmeasured case-mix differences and selection bias may explain the higher mortality risk in the HD population, these results should be interpreted with caution.

    2018-01-01

    Acquired cystic kidney disease (ACKD) is a condition that occurs predominantly in patients with end-stage renal disease (ESRD). In contrast to hereditary cystic kidney disease, ACKD is characterized by the presence of multiple small cysts in bilaterally small kidneys. Limited pediatric data suggest a high incidence (21.6-45.8%) of ACKD in children on dialysis, comparable to that in adults, with an increased frequency associated with a longer duration of dialysis. Recent research has shed light on the pathogenesis of ACKD, such as activation of proto-oncogenes. Although most patients with ACKD are asymptomatic, the condition can be complicated by renal cell carcinoma. Routine surveillance should therefore be considered in at-risk populations.

    To retrospectively analyze the nutritional status and growth and development situation of the children with chronic kidney disease stage 3 to 5 when they were diagnosed at the first visit. After searching for the data of all the hospitalized cases during January 2007 to September 2015 in the Department of Nephrology of Children's Hospital Affiliated to the Capital Institute of Pediatrics from the medical record system, data of 37 cases with complete clinical data were collected; all these cases were diagnosed as chronic kidney disease stage 3 to 5 according to the diagnostic criteria.We recorded these children's age, height, weight, body mass index, albumin, blood lipids and acidosis situation when they were first diagnosed, and then, analyzed and summarized their nutritional status and growth and development situation. In these 37 cases, 24 cases were boys and 13 cases were girls; 23 cases (62%) were shorter than the third percentile of age-sex-specific height; 18 cases (49%) exhibited lower weight than the third percentile of age-sex-specific weight; 5 cases (13.5%) showed lower BMI than the third percentile of height-age BMI, and 5 cases (13.5%) had obesity. The level of albumin was (37.0±8.7) g/L, and no statistically significant difference was observed within each stage. In all of these cases, 10 cases were hypoalbuminemia (27%), and the difference of its frequency between stage 3-4 and stage 5 was not statistically significant. Triglyceride was (2.2±1.1) mmol/L. The mean level was higher than the normal range, but with no statistically significant difference within each stage; 21 cases (62%) were diagnosed as hypertriglyceridemia, which were more frequent compared with the occurrence of the hypercholesterolemia (32%), the high low density lipoprotein (26%) and the low high density lipoprotein(12%). And the occurrence of decompensated metabolic acidosis in stage 5 (69%) was significantly higher than that in stage 3-4 (38%) (P=0.036 6, Growth retardation is

    Tumor tissue can be re-oxygenated by inactivating peroxidase/catalase in the tumor tissue through application of hydrogen peroxide. The hydrogen peroxide in turn is then degraded to produce oxygen. In this way, low-LET (linear energy transfer) radioresistant tumors can be transformed into radiosensitive ones (Ogawa Y, et al: Int J Mol Med 12: 453-458, 845-850, 2003, Ogawa Y, et al: Int J Mol Med 14: 397-403, 2004, Kariya S, et al: Int J Radiat Oncol Biol Phys 75: 449-454, 2009). The purpose of the present study was to establish a non-surgical breast-conservation treatment (KORTUC-BCT) by utilizing a novel Kochi Oxydol-Radiation Therapy for Unresectable Carcinomas, Type II (KORTUC II) radiosensitization treatment. KORTUC I was shown to remarkably enhance radiotherapeutic effects in various types of superficially exposed and locally advanced neoplasms (Ogawa Y, et al: Oncol Rep 19: 1389-1394, 2008). Based on clinical experiences using KORTUC I, a new radiosensitizing agent containing hydrogen peroxide and sodium hyaluronate has been developed for intra-tumoral injection in various tumors which are not superficially exposed. The agent is composed of 0.5% hydrogen peroxide and 0.83% sodium hyaluronate (CD44 molecule). Sodium hyaluronate mixed with hydrogen peroxide attaches to CD44-positive tumor cells, which are generally reported to be breast cancer stem cells. This new method, named KORTUC II, was approved by our local ethics committee for treatment of advanced skin cancer (including malignant melanoma), bone/soft tissue malignant neoplasm, breast cancer and metastatic lymph node. A total of 39 early stage breast cancer patients (stage I: 12 patients and stage II: 27) were enrolled in the KORTUC II trial upon fully informed consent. Mean age of the patients was 61.1 years old. All 39 patients were unable or unwilling to undergo surgery and therefore undertook non-surgical breast-conservation treatment (KORTUC-BCT) by KORTUC II. A maximum of 6 ml of the agent was

    To investigate potential associations between dose to heart (sub)structures and non-cancer death, in early stage non-small cell lung cancer (NSCLC) patients treated with stereotactic body radiation therapy (SBRT). 803 patients with early stage NSCLC received SBRT with predominant schedules of 3×18Gy (59%) or 4×12Gy (19%). All patients were registered to an average anatomy, their planned dose deformed accordingly, and dosimetric parameters for heart substructures were obtained. Multivariate Cox regression and a sensitivity analysis were used to identify doses to heart substructures or heart region with a significant association with non-cancer death respectively. Median follow-up was 34.8months. Two year Kaplan-Meier overall survival rate was 67%. Of the deceased patients, 26.8% died of cancer. Multivariate analysis showed that the maximum dose on the left atrium (median 6.5Gy EQD2, range=0.009-197, HR=1.005, p-value=0.035), and the dose to 90% of the superior vena cava (median 0.59Gy EQD2, range=0.003-70, HR=1.025, p-value=0.008) were significantly associated with non-cancer death. Sensitivity analysis identified the upper region of the heart (atria+vessels) to be significantly associated with non-cancer death. Doses to mainly the upper region of the heart were significantly associated with non-cancer death. Consequently, dose sparing in particular of the upper region of the heart could potentially improve outcome, and should be further studied. Copyright © 2017 Elsevier B.V. All rights reserved.

    Flexor digitorum longus transfer and medial displacement calcaneal osteotomy have shown favourable results in the treatment of adult acquired flat foot deformity stage 2. Little is known about the resorbable interference screw for tendon fixation and postoperative patient satisfaction though. Moreover possible changes of radiographic parameters at final follow-up, possible implant-associated complications and differences concerning clinical results at final follow-up to other studies using bone tunnel techniques for fixation of the FDL tendon were investigated. 21 feet in 21 patients with a mean age of 51 years were evaluated pre- and postoperatively after a standardised operative procedure using MDCO and FDL transfer with interference screw fixation. Patients were evaluated with the American Orthopaedic Foot and Ankle Society Hindfoot Score and the Visual Analogue Scale at an average follow-up of 20 months. Hindfoot radiographic parameters were evaluated according to AOFAS guidelines. For statistical analysis SPSS v.15.0.1 was used. The average AOFAS Score (from 42 to 95 points) and VAS (from 0.5 to 8 points) both increased significantly (p screw fixation for FDL transfer is a safe and promising operative technique, allowing a smaller skin incision without disrupting the normal interconnections at the knot of Henry, while achieving very high patient satisfaction and improving postoperative function as well as relieving pain. This method is technically easy to perform, has a low complication risk and we, therefore, recommend this fixation technique in patients with adult acquired flatfoot deformity stage 2.

    Carnitine palmitoyltransferase II (CPT-II) deficiency is an autosomal recessively inherited disorder involving the β-oxidation of long-chain fatty acids, which leads to rhabdomyolysis and subsequent acute renal failure. The clinical phenotype varies from a severe infantile form to a milder muscle form. Here, we report a 9-year-old boy referred to our hospital for the investigation of hematuria with a 2-day history of dark urine and malaise. As no erythrocytes in the microscopic examination of the urine and hemoglobinuria were present, myoglobinuria due to rhabdomyolysis was the most probable cause of dark urine. After excluding the other causes of rhabdomyolysis, with the help of metabolic investigations, the patient was suspected to have CPT-II deficiency, the most common cause of metabolic rhabdomyolysis. Our aim in presenting this case is to emphasize considering rhabdomyolysis in the differential diagnosis of dark urine in order to prevent recurrent rhabdomyolysis and renal injury.

Patients and methods: The study period was from June 2002 to March 2014. The subjects were 28 patients with a stage II bulky mass in the NAC group and 17 such patients in the Ope group. The chi-square test was used to compare operative time, volume of intraoperative blood loss, use of blood transfusion, and time from surgery to discharge between the two groups. Moreover, the log-rank test using the Kaplan–Meier method was performed to compare disease-free survival (DFS and overall survival (OS between the groups. Results: There were no statistically significant differences between the two groups in operative time, volume of intraoperative blood loss, or use of blood transfusion. However, the time from surgery to discharge was 18 days (14–25 days in the NAC group and 25 days (21–34 days in the Ope group; the patients in the NAC group were discharged earlier (P=0.032. The hazard ratio for DFS in the NAC group as compared with that in the Ope group was 0.36 (95% CI 0.08–0.91, and the 3-year DFS rates were 81.2% and 41.0%, respectively (P=0.028. Moreover, the hazard ratio for OS was 0.39 (95% CI 0.11–1.24, and the 3-year OS rates were 82.3% and 66.4%, respectively (P=0.101. Conclusion: NAC with cisplatin and irinotecan was confirmed to prolong DFS as compared with RH alone. The results of this study suggest that NAC might be a useful adjunct to surgery in the treatment of stage II squamous

    The evaluation of adaptive behavior is informative in children with attention-deficit/hyperactivity disorder (ADHD) or specific learning disorders (SLD). However, the few investigations available have focused only on the gross level of domains of adaptive behavior. To investigate which item subsets of the Vineland-II can discriminate children with ADHD or SLD from peers with typical development. Student's t-tests, ROC analysis, logistic regression, and linear discriminant function analysis were used to compare 24 children with ADHD, 61 elementary students with SLD, and controls matched on age, sex, school level attended, and both parents' education level. Several item subsets that address not only ADHD core symptoms, but also understanding in social context and development of interpersonal relationships, allowed discrimination of children with ADHD from controls. The combination of four item subsets (Listening and attending, Expressing complex ideas, Social communication, and Following instructions) classified children with ADHD with both sensitivity and specificity of 87.5%. Only Reading skills, Writing skills, and Time and dates discriminated children with SLD from controls. Evaluation of Vineland-II scores at the level of item content categories is a useful procedure for an efficient clinical description. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Objective: To examine the association between rs10938397 polymorphism in glucosamine-6-phosphate deaminase 2 ( GNPDA2 ) and risk of obesity in children at different stages of development and analyze the differences in the association. Methods: A total of 3 503 school-aged children were selected from the Beijing Child and Adolescent Metabolic Syndrome (BCAMS) study in Beijing and their complete anthropometry weight, height, fat mass percentage (FMP), fat mass index (FMI) and free fat mass index (FFMI) and sexual maturation (SM) data were used. The developmental stages were evaluated using male testicular volume and female breast Tanner staging. FMP, FM and FFM were measured by bioelectrical impedance analysis. General obesity and adiposity were respectively defined according to Chinese sex-age-specific body mass index (BMI) cutoffs and sex-age-specific FMP cutoffs. The SNP rs10938397 were genotyped by the TaqMan Allelic Discrimination Assay with the GeneAmp 7900 sequence detection system (Applied Biosystems, Foster city, CA, USA). Relationships between rs10938397 polymorphism and BMI, FMP, FMI and FFMI and different types of obesity were tested using multivariate linear regression and logistic regression models. Results: After age adjustment and correction for multiple testing, the rs10938397-G was associated with BMI and risk of general obesity in boys in early puberty ( β =0.328, P =0.001; OR =1.420, 95% CI : 1.126-1.790), and the rs10938397-G was associated with BMI in girls in late puberty ( β =0.266, P =0.001). The associations of GNPDA2 rs10938397-G with FFMI and FMI were observed in boys in early puberty ( β =0.137, P =0.016; β =0.202, P =0.007) and the associations of rs10938397-G with FMP and FMI were observed in girls in late puberty ( β =0.153, P =0.002; β =0.168, P =0.001). The rs10938397-G was also associated with adiposity in girls in late puberty ( OR =1.339, 95% CI : 1.093-1.637). Conclusion: The rs10938397 polymorphism in GNPDA2 is associated

    1978-03-22

    In this preliminary report for Phase II of Health Education Authority of Louisiana's (HEAL) ICES program, specific elements of the basic intitutional issues were readdressed, as requested by the U.S. Department of Energy. The draft environmental assessment was reassessed and updated. Thermal energy demand profiles for the major community sectors, i.e., the five institutions comprising the HEAL Complex, were refined on a month-by-month basis and resulted in establishing ICES plant systems design capacities of 121,500 pounds per hour demand and 418,175,000 pounds per year for steam; 10,000 tons demand and 38,885,000 ton-hours per year for cooling. From these values the concept of the plant was developed. The Phase I capital cost estimate was updated. Total capital cost is now indicated as $29,960,500. The Phase I operating cost estimate was updated, with that figure now $8,468,479. The Phase I financial analysis was updated, producing an estimated annual revenue level of $9,907,062.

    The therapeutic options related to chronic organ failure are interconnected to the variability of human biological responses and the personal history and choices of the chronically ill patient on one hand, and with the variable human answers to therapies on the other hand. All these aspects may explain the small number and low quality of studies aimed to define the clinical criteria useful in identifying end-stage chronically ill patients, as highlighted through the 2012-2013 Medline survey performed by the task force. These results prevented the grading of scientific evidence. However, taking into account the evidence based medicine definition, the task force believes the clinical reasoning and the individual experience of clinicians as well as the patients and families preferences cannot be replaced "tout court" with a strict methodological research. Accordingly, the working method selected by the task force members was to draw up a set of clinical parameters based on the available scientific literature, submitting it to a peer review process carried out by an expert panel. This paper discusses a set of clinical parameters included in the clinical decision-making algorithm and shared by nine medical societies. For each chronic organ failure these clinical parameters should be intended not as a rigid cutoff system to make a choice between two selected care options (intensive vs palliative), rather as the starting point for a joint and careful consideration regarding the opportunity to adopt the clinical decision-making algorithm care proposed in Part I.

    In this study, the in vitro activities of a natural sesquiterpene, alpha-cyperotundone, isolated from the root bark of Maytenus retusa and a cobalt(II)-complex of a natural occurring prenyl hydroxynaphthoquinone (lapachol) were evaluated against the trophozoite stage of Acanthamoeba castellanii Neff using a previously developed colorimetric 96-well microtiter plate assay, based on the oxido-reduction of Alamar Blue(R). The obtained activities showed that these two compounds were able to inhibit the in vitro growth of the amoebae at relatively low concentrations. Further identification of the molecular targets of these products and their effects on acanthamoebae should be determined to evaluate their possible therapeutic use. Copyright 2010.

    Morphometric and catecholamine-binding properties of erythrocytes were studied as were their changes in monotherapy with Renitec, an inhibitor of the angiotensin-converting enzyme, of patients with stage II hypertensive disease, using the image digital analysis computing system VIDAS-386 (Kontron Electronik, Germany). Patients with hypertensive disease were shown to develop degenerative changes in their erythrocytes, with catecholamine accumulation in them being a prominent feature, these events taking their course against the background of abnormalities in primary parameters characterizing cardiochemodynamics and regulation of the heart's rhythm. The above patients derived apparent benefit from treatment with Renitec, which fact was evidenced by improvement in parameters associated with the cardiochemodynamics and regulation of the cardiac rhythm, by alleviating the degree of severity of degenerative changes in erythrocytes, and by increase in their content of catecholamines.

    To identify the prognostically highest risk patients, DNA content and p53 nuclear or cytoplasmic accumulation, evaluated by monoclonal antibody DO7 and polyclonal antibody CM1, were determined in 94 surgically resected stage II (Dukes B2) colorectal cancers, treated or not with adjuvant 5-fluorouracil-based chemotherapy. Sixty-one (65%) of the tumors were aneuploid, 16 (17%) of which had a multiploid DNA content; 50 (53%) displayed DO7 nuclear p53 accumulation, and 44 (47%) showed cytoplasmic CM1 positivity. In multivariate analysis, only multiploidy and p53 nuclear positivity emerged as independent prognostic indicators of a poorer outcome. Positivity for p53 was associated with shorter survival in 5-fluorouracil-treated and untreated patients. Therefore, in patients with Dukes B2 colorectal cancer, a biologic profile based on the combined evaluation of DNA multiploidy and p53 status can provide valuable prognostic information, identifying patients to be enrolled in alternative, more aggressive therapeutic trials.

  14. Evidence for transitional stages in the evolution of euglenid group II introns and twintrons in the Monomorphina aenigmatica plastid genome.

    Full Text Available Photosynthetic euglenids acquired their plastid by secondary endosymbiosis of a prasinophyte-like green alga. But unlike its prasinophyte counterparts, the plastid genome of the euglenid Euglena gracilis is riddled with introns that interrupt almost every protein-encoding gene. The atypical group II introns and twintrons (introns-within-introns found in the E. gracilis plastid have been hypothesized to have been acquired late in the evolution of euglenids, implying that massive numbers of introns may be lacking in other taxa. This late emergence was recently corroborated by the plastid genome sequences of the two basal euglenids, Eutreptiella gymnastica and Eutreptia viridis, which were found to contain fewer introns.To gain further insights into the proliferation of introns in euglenid plastids, we have characterized the complete plastid genome sequence of Monomorphina aenigmatica, a freshwater species occupying an intermediate phylogenetic position between early and late branching euglenids. The M. aenigmatica UTEX 1284 plastid genome (74,746 bp, 70.6% A+T, 87 genes contains 53 intron insertion sites, of which 41 were found to be shared with other euglenids including 12 of the 15 twintron insertion sites reported in E. gracilis.The pattern of insertion sites suggests an ongoing but uneven process of intron gain in the lineage, with perhaps a minimum of two bursts of rapid intron proliferation. We also identified several sites that represent intermediates in the process of twintron evolution, where the external intron is in place, but not the internal one, offering a glimpse into how these convoluted molecular contraptions originate.

    STUDY DESIGN Controlled laboratory, repeated measures. BACKGROUND Posterior tibial tendon dysfunction is a common musculoskeletal problem that includes tendon degeneration and collapse of the medial arch of the foot (flatfoot deformity). Ankle-foot orthoses (AFOs) typically are used to correct flatfoot deformity. Correction of flatfoot deformity involves increasing forefoot adduction, forefoot plantar flexion, and hindfoot inversion. OBJECTIVES To test whether a foot orthosis with a lateral extension reduces forefoot abduction in patients with stage II posterior tibial tendon dysfunction while walking. METHODS The gait of 15 participants with stage II posterior tibial tendon dysfunction was evaluated under 3 conditions: a standard AFO, an AFO with a lateral extension, and a shoe-only control condition. Kinematic variables of interest were evaluated at designated time points in the gait cycle and included hindfoot inversion/eversion, forefoot plantar flexion/dorsiflexion, and forefoot abduction/adduction. A 3-by-4, repeated-measures analysis of variance (brace condition by gait phase) was used to compare variables across conditions. RESULTS The AFO with a lateral extension resulted in a significantly greater change in forefoot adduction compared to the standard AFO (2.6°, P = .02) and shoe-only conditions (4.1°, P<.01) across all phases of stance. Forefoot plantar flexion was significantly increased when comparing the standard AFO and AFO with a lateral extension to the shoe-only condition. The AFO with the lateral extension also demonstrated significantly increased hindfoot inversion during the loading response and terminal stance phases. CONCLUSION Off-the-shelf and standard AFOs have been shown to improve forefoot plantar flexion and hindfoot eversion, but not forefoot adduction. A lateral extension added to a standard AFO along the forefoot significantly improved forefoot adduction in participants with posterior tibial tendon dysfunction while walking. PMID

    Purpose: A possible association between thyroid diseases (TD) and breast cancer (BC) has been debated. We examined prevalence and development of TD in women after multimodal treatment for Stage II/III BC compared with women from a general population. Secondarily, we explored the impact of two different radiotherapy (RT) techniques (standardized field arrangements vs. computed tomography [CT]-based dose planning) on TD in BC patients examined 35-120 months after primary BC treatment. Methods and Materials: A total of 403 BC patients completed a questionnaire about TD and had blood samples taken for analyses of thyroid function. All had undergone postoperative RT with or without (2%) adjuvant systemic treatment. The results in the BC patients were compared with a cancer-free, age-matched control group from a general population (CGr). Results: There was higher prevalence of self-reported hypothyroidism in the BC patients as compared with the CGr (18% vs. 6%, p < 0.001). The raised prevalence was predominantly due to a substantial increase in the development of hypothyroidism after BC diagnosis, whereas the prevalence of hypothyroidism before BC diagnosis was similar to that observed in the CGr. Patients treated with CT-based RT showed a trend for increased post-BC development of hypothyroidism as compared with those treated with standardized field arrangements (p = 0.08). Conclusions: Hypothyroidism is significantly increased in women after multimodal treatment for Stage II/III BC. Radiation to the thyroid gland may be a contributing factor. BC patients should be routinely screened for hypothyroidism.

    Elderly patients with non-small cell lung cancer (NSCLC) are frequently treated with radiation therapy (RT) alone, due to poor performance status or underlying disease. We investigated the effectiveness of RT over 60 Gy administered alone to NSCLC patients who were unfit or rejecting for combination treatment. From April 2002 to July 2010, 83 patients with stage II-III NSCLC, aged over 60 years, treated by RT alone with a curative aim were analyzed. Radiation was targeted to the primary tumor and clinically involved lymph nodes. A total dose of 66 Gy in 30 fractions (2.2 Gy/fraction) was delivered once daily (5 fractions weekly). One month after completing RT, initial tumor responses were evaluated. Median age of patients was 73 years (range, 60 – 82 years). The median survival time was 18.6 months (range, 2–135). The actuarial overall survival rates at 2 and 3 years were 39 % and 23 %, and cause-specific survival rate at 2 and 3 years were 57 % and 47 %, respectively. When primary tumor was controlled, the 2- and 3-year CSS were 56 % and 45 %, but 32 % and 23 % in those patients with local failure, respectively (P = 0.017). Additionally, the local control rate was associated with the initial tumor response (P = 0.01). No patient experienced grade 4+ toxicity. For stage II-III NSCLC patients aged over 60 years and unfit or rejecting for combination treatment, RT alone showed promising result. Long-term disease control can be expected if an early tumor response to radiation is achieved, which could result in improved overall survival rates

    Cancer stem cells (CSCs) are notorious for their capacity of tumor progression, metastasis or resistance to chemo-radiotherapy. However, the undisputed role of cancer stem marker, CD133, in colorectal cancers (CRCs) is not clear yet. We assessed 271 surgically-resected stage II and III primary CRCs with (171) and without (100) adjuvant therapy after surgery. CD133 expression was analyzed by immunohistochemical (IHC) staining and real-time RT-PCR. CD133 promoter methylation was quantified by pyrosequencing. The CD133 IHC expression was significantly correlated with mRNA expression (p=0.0257) and inversely correlated with the promoter methylation (p=0.0001). CD133 was expressed more frequently in rectal cancer (p=0.0035), and in moderately differentiated tumors (p=0.0378). In survival analysis, CD133 expression was not significantly correlated with overall survival (OS) (p=0.9689) as well as disease-free survival (DFS) (p=0.2103). However, CD133+ tumors were significantly associated with better OS in patients with adjuvant therapy compared to those without adjuvant therapy (p<0.0001, HR 0.125, 95% CI 0.052-0.299). But the patients with CD133- tumors did not show any significant difference of survival according to adjuvant therapy (p=0.055, HR 0.500, 95% CI 0.247-1.015). In stage II and III CRCs, CD133 IHC expression may signify the benefit for adjuvant therapy although it is not an independent prognostic factor

    The purpose of this study was to clarify the relationships between upper airway factors (nasal resistance, adenoids, tonsils, and tongue posture) and maxillofacial forms in Class II and III children. Sixty-four subjects (mean age, 9.3 years) with malocclusion were divided into Class II and Class III groups by ANB angles. Nasal resistance was calculated using computational fluid dynamics from cone-beam computed tomography data. Adenoids, tonsils, and tongue posture were evaluated in the cone-beam computed tomography images. The groups were compared using Mann-Whitney U tests and Student t tests. The Spearman rank correlations test assessed the relationships between the upper airway factors and maxillofacial form. Nasal resistance of the Class II group was significantly larger than that of the Class III group (P = 0.005). Nasal resistance of the Class II group was significantly correlated with inferior tongue posture (P Class III group was significantly correlated with anterior tongue posture (P Class III group was significantly correlated with mandibular protrusion. The relationships of upper airway factors differ between Class II and Class III children. Copyright © 2017 American Association of Orthodontists. Published by Elsevier Inc. All rights reserved.

  20. COLLISIONS BETWEEN GRAVITY-DOMINATED BODIES. II. THE DIVERSITY OF IMPACT OUTCOMES DURING THE END STAGE OF PLANET FORMATION

    Numerical simulations of the stochastic end stage of planet formation typically begin with a population of embryos and planetesimals that grow into planets by merging. We analyzed the impact parameters of collisions leading to the growth of terrestrial planets from recent N-body simulations that assumed perfect merging and calculated more realistic outcomes using a new analytic collision physics model. We find that collision outcomes are diverse and span all possible regimes: hit-and-run, merging, partial accretion, partial erosion, and catastrophic disruption. The primary outcomes of giant impacts between planetary embryos are approximately evenly split between partial accretion, graze-and-merge, and hit-and-run events. To explore the cumulative effects of more realistic collision outcomes, we modeled the growth of individual planets with a Monte Carlo technique using the distribution of impact parameters from N-body simulations. We find that fewer planets reached masses >0.7 M Earth using the collision physics model compared to simulations that assumed every collision results in perfect merging. For final planets with masses >0.7 M Earth , 60% are enriched in their core-to-mantle mass fraction by >10% compared to the initial embryo composition. Fragmentation during planet formation produces significant debris (∼15% of the final mass) and occurs primarily by erosion of the smaller body in partial accretion and hit-and-run events. In partial accretion events, the target body grows by preferentially accreting the iron core of the projectile and the escaping fragments are derived primarily from the silicate mantles of both bodies. Thus, the bulk composition of a planet can evolve via stochastic giant impacts.

    In patients with high risk stage II and stage III colon cancer (CC), curative surgery followed by adjuvant FOLFOX-4 chemotherapy has become the standard of care. However, for 20 to 30 % of these patients, the current curative treatment strategy of surgical excision followed by adjuvant chemotherapy fails either to clear locoregional spread or to eradicate distant micrometastases, leading to disease recurrence. Preoperative chemotherapy is an attractive concept for these CCs and has the potential to impact upon both of these causes of failure. Optimum systemic therapy at the earliest possible opportunity may be more effective at eradicating distant metastases than the same treatment given after the delay and immunological stress of surgery. Added to this, shrinking the primary tumor before surgery may reduce the risk of incomplete surgical excision, and the risk of tumor cell shedding during surgery. PRODIGE 22 - ECKINOXE is a multicenter randomized phase II trial designed to evaluate efficacy and feasibility of two chemotherapy regimens (FOLFOX-4 alone and FOLFOX-4 + Cetuximab) in a peri-operative strategy in patients with bulky CCs. Patients with CC deemed as high risk T3, T4 and/or N2 on initial abdominopelvic CT scan are randomized to either colectomy and adjuvant chemotherapy (control arm), or 4 cycles of neoadjuvant chemotherapy with FOLFOX-4 (for RAS mutated patients). In RAS wild-type patients a third arm testing FOLFOX+ cetuximab has been added prior to colectomy. Patients in the neoadjuvant chemotherapy arms will receive postoperative treatment for 4 months (8 cycles) to complete their therapeutic schedule. The primary endpoint of the study is the histological Tumor Regression Grade (TRG) as defined by Ryan. The secondary endpoints are: treatment strategy safety (toxicity, primary tumor related complications under chemotherapy, peri-operative morbidity), disease-free and recurrence free survivals at 3 years, quality of life, carcinologic quality and

    Full Text Available Background. Evidence of the effects of HIV infection and clinical stage on the duration of refeeding and treatment (DRT and the rate of weight gain (RWG in severely malnourished children remains inconclusive. Objectives. To determine whether the RWG and DRT differ by baseline clinical characteristics, and to assess the effect of HIV status and disease stage on the relationship between these two clinical outcomes. Methods. This was a retrospective record review of 346 patiens discharged between 2009 and 2013 following treatment for severe acute malnutrition (SAM at two rural hospitals in South Africa. Results. A third of the sample was HIV-positive, the RWG (measured as g/kg/day was significantly slower in HIV-positive patients compared with HIV-negative cases (mean 5.2, 95% confidence interval (CI 4.47 - 5.93 v. mean 8.51; CI 7.98 - 9.05; p<0.0001 and cases at stage IV of HIV infection had a significantly slower RWG (mean 3.97; CI 2.33 - 5.61 compared with those at stages I (mean 7.64; CI 6.21 - 9.07 (p<0.0001 and II (mean 5.87; CI 4.74 - 6.99. The mean DRT was longer in HIV-positive cases and those at advanced stages of HIV infection. HIV-positive cases were renourished and treated for almost 3.5 times longer than their HIV-negative counterparts to achieve a moderate RWG (5 - 10 g/kg/day. Conclusion. This study highlights the need to reconsider energy requirements for HIV-positive cases at different clinical stages, for more rapid nutritional recovery in under-resourced settings where prolonged hospitalisation may be a challenge.

    The G1 stage of chronic kidney disease (CKD) is defined in the 2012 KDIGO Guideline as kidney damage characterized by structural or functional kidney abnormalities without deterioration of glomerular filtration rate. Albuminuria and electrolyte abnormalities due to tubular disorders are considered functional markers of kidney damage. Changes in renal water handling are not explicitly cited in these guidelines. A large sample of children with abnormal dimercaptosuccinic acid (DMSA) scan located in the G1 stage was used in this study. Ambispective, cross-sectional study to evaluate the clinical histories of 116 pediatric patients. 100 patients were included in the first group (G1 stage) and 16 patients in the G2-G5 stages according to the classification of CKD Guideline KDIGO. All the patients had a renal pathologic DMSA scan. GFR, maximum urine osmolality and albumin/creatinine and NAG/creatinine ratios were determined. The patients with normal GFR, in relation to those with reduced GFR, had significantly higher values of maximum urine osmolality and significantly reduced values of urine volume and albumin/creatinine and NAG/creatinine ratios. The most frequently observed alterations in children in the KDIGO G1 stage were those involving the water renal management such as urinary concentrating ability defect (29%) and increased urinary volume (20%). The frequency of children with increased urinary elimination of albumin (12%) and NAG (3%) was more lower. All children in KDIGO G2-G5 stages had alterations in water renal management. The parameters related with the water renal management are affected more frequently than albumin urinary excretion in children who have loss of parenchyma and normal GFR.

    The aims of UKWT2 included consolidating the results for stage III patients obtained in UKWT1 and improving the outcome for patients with inoperable tumours by giving vincristine, actinomycin-D and doxorubicin in an intensive schedule (Intensive AVA). The second UK WT trial (UKWT2) ran between July 1986 and September 1991 accruing 448 patients. One hundred and six patients were diagnosed and treated for stage III disease. Six had clear cell sarcoma of the kidney (CCSK) and seven had rhabdoid tumours of the kidney (RTK) and are analysed separately. One other patient was excluded from overall analysis. Ninety-two patients were followed for a median of 115 months. Seventy-five received standard chemotherapy and abdominal radiotherapy according to protocol. Seventeen had stage III disease at immediate nephrectomy, but radiotherapy was omitted by physician choice. Thirty-three patients had inoperable disease at diagnosis and received pre-nephrectomy chemotherapy. Overall survival (OS) at 4 years for stage III favourable histology (FH) patients receiving abdominal RT was 83% (CI: 73-89). For children with stage III disease in whom RT was omitted the OS was 82% (CI: 59-97) and for inoperable disease 94% (CI: 78-98). The overall and event-free survival (EFS) of children with stage III CCSK was 100% and was achieved with the majority of patients not receiving radiotherapy (CI: 48-100). Three of seven children with RTK are alive EFS and OS 43% (CI: 10-73). For patients treated by abdominal radiotherapy the overall local control rate was 94.4% (CI: 86.4-98.5*%), 96.7% (CI: 88.5-99.6%) for flank RT and 83.3% (51.6-98.0%) for whole abdominal radiotherapy (WRT). The outcome for stage III FH disease was similar to that reported for UKWT1 and NWTS-3. The combination of abdominal RT together with 3-drug chemotherapy achieves a high abdominal tumour control rate. Flank RT is probably sufficient for localised tumour rupture. The high cure rates for children in this trial with

    Simon's two-stage design is one of the most commonly used methods in phase II clinical trials with binary endpoints. The design tests the null hypothesis that the response rate is less than an uninteresting level, versus the alternative hypothesis that the response rate is greater than a desirable target level. From a Bayesian perspective, we compute the posterior probabilities of the null and alternative hypotheses given that a promising result is declared in Simon's design. Our study reveals that because the frequentist hypothesis testing framework places its focus on the null hypothesis, a potentially efficacious treatment identified by rejecting the null under Simon's design could have only less than 10% posterior probability of attaining the desirable target level. Due to the indifference region between the null and alternative, rejecting the null does not necessarily mean that the drug achieves the desirable response level. To clarify such ambiguity, we propose a Bayesian enhancement two-stage (BET) design, which guarantees a high posterior probability of the response rate reaching the target level, while allowing for early termination and sample size saving in case that the drug's response rate is smaller than the clinically uninteresting level. Moreover, the BET design can be naturally adapted to accommodate survival endpoints. We conduct extensive simulation studies to examine the empirical performance of our design and present two trial examples as applications. © 2018, The International Biometric Society.

    2011-01-01

    This paper describes the use of targeted Loci/CHEM CFD simulations to evaluate the effects of a dual-engine first-stage hot-fire test on an evolving integrated launch pad/test article design. This effort was undertaken as a part of the NESC Independent Assessment of the Taurus II Stage Test Series. The underlying conceptual model included development of a series of computational models and simulations to analyze the plume induced environments on the pad, facility structures and test article. A pathfinder simulation was first developed, capable of providing quick-turn around evaluation of plume impingement pressures on the flame deflector. Results from this simulation were available in time to provide data for an ongoing structural assessment of the deflector. The resulting recommendation was available in a timely manner and was incorporated into construction schedule for the new launch stand under construction at Wallops Flight Facility. A series of Reynolds-Averaged Navier-Stokes (RANS) quasi-steady simulations representative of various key elements of the test profile was performed to identify potential concerns with the test configuration and test profile. As required, unsteady Hybrid-RANS/LES simulations were performed, to provide additional insight into critical aspects of the test sequence. Modifications to the test-specific hardware and facility structures thermal protection as well as modifications to the planned hot-fire test profile were implemented based on these simulation results.

    Purpose/Objective: The treatment of inoperable Stage III NSCLC with conventional RT alone results in a high incidence of local and distant failures and in very limited long-term survival rates. In two consecutive phase II cooperative trials, we evaluated the combination of alternating hyperfractionated accelerated radiotherapy and cisplatin-based chemotherapy. Materials and Methods: A total of one hundred and thirty two patients were enrolled. Between 2/86 and 9/89, 65 patients were entered in the first trial (G.I) and between 12/89 and 10/92 67 were enrolled in the second trial (G.II). In both protocols, RT was administered twice daily, with 6 hours interval, 5 days a week, to a total dose of 63 Gy in 42 fractions of 1.5 Gy. RT was given during weeks 2, 3 and 6, 7, over an elapsed time of 6 weeks. In G.I, 3 cycles of cisplatin, 60 mg/m2 d.1, mitomycin, 8 mg/m2 d.1 and vindesin 3 mg/m2 d.1 and 8, were given during weeks 1, 5 and 9, whereas in G.II, cisplatin 70 mg/m2 d.1 and vinblastin 5 mg/m2 d.1 and 8 were given during weeks 1, 5, 9, 13, 17 and 21. Patients' characteristics included the following : median age was 55.5 years (28-70), male to female ratio was 7.3 : 1, tumor Stage were III A in 44% and III B in 56%, performance status (P.S.) were 0 in 36%, 1 in 52% and 2 in 12%. Histologic type consisted in squamous cell carcinoma in 60%, adenocarcinoma in 22%, large cell carcinoma in 14% and undifferentiated NSCLC in 4%. Results: With a minimum follow-up of 3 years, the 1, 2, 5 and 8 year overall survival probability was 56% (95% C.I. 47% - 64%), 27% (20% - 35%), 12% (7% - 18%) and 9% (3% - 16%) respectively, with a median survival of 13.6 months (11.4 - 16.8). Median follow-up for survivors was 6 years (3.3 - 9.9). There were no survival differences between Stage III A and III B (p = .84), PS 0, ,, 2 (p = .87), sex (p = .45) or between the two treatment protocols. At this time, 14 patients are alive, and 118 have died : 102 from NSCLC, 4 from acute toxicity, 2

    Full Text Available Abstract Background Early relapse in colorectal cancer (CRC patients is attributed mainly to the higher malignant entity (such as an unfavorable genotype, deeper tumor invasion, lymph node metastasis and advance cancer stage and poor response to chemotherapy. Several investigations have demonstrated that genetic polymorphisms in drug-targeted genes, metabolizing enzymes, and DNA-repairing enzymes are all strongly correlated with inter-individual differences in the efficacy and toxicity of many treatment regimens. This preliminary study attempts to identify the correlation between genetic polymorphisms and clinicopathological features of CRC, and evaluates the relationship between genetic polymorphisms and chemotherapeutic susceptibility of Taiwanese CRC patients. To our knowledge, this study discusses, for the first time, early cancer relapse and its indication by multiple genes. Methods Six gene polymorphisms functional in drug-metabolism – GSTP1 Ile105Val, ABCB1 Ile1145Ile, MTHFR Ala222Val, TYMS double (2R or triple (3R tandem repeat – and DNA-repair genes – ERCC2 Lys751Gln and XRCC1 Arg399Gln – were assessed in 201 CRC patients using a polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP technique and DNA sequencing. Patients were diagnosed as either high-risk stage II (T2 and 3 N0 M0 or III (any T N1 and 2 M0 and were administered adjuvant chemotherapy regimens that included 5-fluorouracil (5FU and leucovorin (LV. The correlations between genetic polymorphisms and patient clinicopathological features and relapses were investigated. Results In this study, the distributions of GSTP1 (P = 0.003, ABCB1 (P = 0.001, TYMS (P ERCC2 (P XRCC1 (P = 0.006 genotypes in the Asian population, with the exception of MTHFR (P = 0.081, differed significantly from their distributions in a Caucasian population. However, the unfavorable genotype ERCC2 2251A>C (P = 0.006, tumor invasion depth (P = 0.025, lymph node metastasis (P = 0

    The blood-stage malaria vaccine FMP2.1/AS02A, comprised of recombinant Plasmodium falciparum apical membrane antigen 1 (AMA1) and the adjuvant system AS02A, had strain-specific efficacy against clinical malaria caused by P. falciparum with the vaccine strain 3D7 AMA1 sequence. To evaluate a potential correlate of protection, we measured the ability of participant sera to inhibit growth of 3D7 and FVO strains in vitro using high-throughput growth inhibition assay (GIA) testing. Sera from 400 children randomized to receive either malaria vaccine or a control rabies vaccine were assessed at baseline and over two annual malaria transmission seasons after immunization. Baseline GIA against vaccine strain 3D7 and FVO strain was similar in both groups, but more children in the malaria vaccine group than in the control group had 3D7 and FVO GIA activity ≥15% 30 days after the last vaccination (day 90) (49% vs. 16%, pvaccine group was 7.4 times the mean increase in the control group (pvaccination (day 364) and did not correlate with efficacy in the extended efficacy time period to day 730. In Cox proportional hazards regression models with time-varying covariates, there was a slight suggestion of an association between 3D7 GIA activity and increased risk of clinical malaria between day 90 and day 240. We conclude that vaccination with this AMA1-based malaria vaccine increased inhibition of parasite growth, but this increase was not associated with allele-specific efficacy in the first malaria season. These results provide a framework for testing functional immune correlates of protection against clinical malaria in field trials, and will help to guide similar analyses for next-generation malaria vaccines. Clinical trials registry: This clinical trial was registered on clinicaltrials.gov, registry number NCT00460525.

    The aim of this study was to determine whether postoperative radiation therapy (PORT) is associated with an overall survival (OS) benefit in patients with completely resected Masaoka or Masaoka-Koga stage II and III thymoma. All patients with completely resected (R0) stage II or III thymoma were identified in a large database of the International Thymic Malignancy Interest Group. Clinical, pathologic, treatment, and follow-up information were extracted. OS was the primary end point. A univariate analysis using the log-rank test was performed, and a multivariate Cox model was created to identify factors associated with OS. Of 1263 patients meeting the selection criteria, 870 (69%) had stage II thymoma. The WHO histologic subtype was A/AB in 360 patients (30%) and B1/B2/B3 in 827 (70%). PORT was given to 55% of patients (n = 689), 15% (n = 180) received chemotherapy, and 10% (n = 122) received both. The 5- and 10-year OS rates for patients having undergone an operation plus PORT were 95% and 86%, respectively, compared with 90% and 79% for patients receiving an operation alone (p = 0.002). This OS benefit remained significant when patients with stage II (p = 0.02) and stage III thymoma (p = 0.0005) were analyzed separately. On multivariate analysis, earlier stage, younger age, absence of paraneoplastic syndrome, and PORT were significantly associated with improved OS. We observed an OS benefit with the use of PORT in completely resected stage II and III thymoma. In the absence of a randomized trial, this represents the most comprehensive analysis of individual patient data and strong evidence in favor of PORT in this patient population.

    This study aimed to compare the quality of life of children and adolescents in various stages of their chronic kidney disease (CKD) who were managed with different treatment modalities to that of children and adolescents without any chronic disease. The study included 18 renal transplant and 21 dialysis patients (8 on hemodialysis, 13 on peritoneal dialysis) and 16 patients who did not yet require renal replacement therapy. The control group consisted of 37 children without any chronic disease. Psychosocial Health Summary scores, Physical Health Summary scores, and Total Scale scores of Pediatric Quality of Life Inventory scores were estimated for the groups. CKD patients had lower scores in all scales of Pediatric Quality of Life Inventory than the control group. There were no differences in self-reported scores on the Pediatric Quality of Life scale scores between treatment groups; however, parents of the transplant patients had reported higher (more favorable) Physical Health Summary scores than those of the dialysis patients. Reports of parents and their children differed only in Physical Health Summary scores in the dialysis group; self-reports of the children were more favorable. These findings show that children and adolescents with CKD experience impaired quality of life on the physical and psychosocial functioning domains in comparison with healthy controls. The study findings implicate the need for further studies to investigate the quality of life in CKD patients at different stages as well as the perceptional differences between pediatric and adolescent CKD patients and caregiver proxy-reports about their quality of life.

    Purpose/Objective: To report on two consecutive Phase II cooperative trials in which we evaluated the combination of alternating hyperfractionated accelerated radiotherapy and cisplatin-based chemotherapy in inoperable Stage III non-small cell lung cancer (NSCLC). Patients and Methods: Between February 1986 and September 1989, 65 patients were entered in the first trial (GOTHA I), and between December 1989 and October 1992 67 were enrolled in the second trial (GOTHA II). In both protocols, radiotherapy (RT) was administered twice daily, at 6 h intervals, 5 days a week, to a total dose of 63 Gy in 42 fractions of 1.5 Gy. RT was given during weeks 2, 3, 6, and 7, over an elapsed time of 6 weeks. In GOTHA I, three cycles of cisplatin, 60 mg/m 2 day 1, mitomycin, 8 mg/m 2 day 1, and vindesin 3 mg/m 2 day 1 and the first day of the following week, were given during weeks 1, 5, and 9; in GOTHA II, cisplatin 70 mg/m 2 day 1 and vinblastin 5 mg/m 2 day 1 and the first day of the following week were given during weeks 1, 5, 9, 13, 17, and 21. Results: With a minimum follow-up of 3 years, the 1-, 2-, 5-, and 8-year overall survival probability was 56% (95% CI 47-64%), 27% (20-35%), 12% (7-18%) and 9% (3-16%), respectively, with a median survival of 13.6 months (11.4-16.8). Median follow-up for survivors was 6 years (3.3-9.9). There were no survival differences between Stages IIIA and IIIB (p = 0.84), performance status 0, 1, 2 (p = 0.87), sex (p = 0.45) or between the two treatment protocols. At this time, 14 patients are alive, and 118 have died: 102 from NSCLC, 4 from acute toxicity, 2 from secondary surgery, 4 from other medical causes, and 6 from unknown causes. Correlation between response and long-term survival was poor, since of the 24 patients who survived 3 years or more, only 6 (25%) were classified as having a complete response; the remainder having either a partial response (11, 46%), no change (6, 25%), or 'progressive disease' (1, 4%).

    To assess the oral health status of the child population and its evolution over the 2004-2010 period. A descriptive cross-sectional study of the entire schoolchild population of the Valencia region of Spain was conducted using cluster sampling. Seventy schools were selected. The sample size was 1373 pupils, aged 6, 12 and 15 years. The children were examined in November and December 2010, at their schools, by 6 examiners calibrated in the ICDAS II method. The descriptive statistics, comparison of means and comparison of proportions (p0) was 30% in primary dentition at 6 years and 37.7% and 43.6% in permanent dentition at 12 and 15 years respectively. At 6, 12 and 15 years, the df.t/DMF. TICDASII 4-6 scores were 0.98, 0.83 and 1.08, the df.s/DMF.SICDASII 4-6 scores were 1.43, 1.27 and 1.64 and the care index results were 14.3%, 59% and 71.3% respectively. Both the caries indices (df.t at 6 years and DMF.T at 12 and 15) and caries prevalence have improved, as the values obtained were lower than in 2004. Using the comparison at 95% CI, between both years, the improvement was only noticeable in the 15 year-old group. The care index continued to be low at 6 years of age but higher values than in 2004 were found at 12 and 15 years. Social class continued to influence the child caries indicators.

    Poststreptococcal sequelae, especially acute rheumatic fever/rheumatic heart disease continues to occur in significant proportions in many parts of the world, especially in less developed countries. An important factor in the study of rheumatic heart disease is the human genetic susceptibility to the disease. The aim of the present study was to detect the most prevalent HLA class I and class II types associated with risk of rheumatic heart disease in Egyptian children. Our study was performed on 100 patients with rheumatic valvular heart diseases and 71 control subjects. Patients were recruited from the Heart Institute, Embaba, Egypt. HLA typing for HLA class I was performed by serotyping and HLDR allele genotyping was performed using INNO-LiPA kits. In the study of HLA class I, there was a statistically significant increase in the B5 allele (P = 0.03; odds ratio, 3.46 [1.12-10.72]) in patients compared to controls, while B49 and B52 alleles (P = 0.004 and P = 0.02) were found in controls only. There was a statistically significant increase in HLA DR* 04-02, 3.46 (1.12-10.72) and HLA DR *10-0101 5.75 (1.27-25.98) in patients. Meanwhile HLA DR*1309120 was found only in controls (P = 0.02). Our study provides further information on the genetic predisposition for rheumatic valvular disease and the protective genotypes in rheumatic heart disease. Further insight into the molecular mechanisms of the disease will be a useful tool for predicting clinical outcome in those patients and, thus, potentially offer new means and approaches to treatment and prophylaxis, including a potential vaccine.

    Klotho G-395-A gene polymorphism may impact children with end-stage renal disease (ESRD). We investigated the relevance of Klotho G-395-A on ESRD development and progression, and its relationship with evolution of cardiovascular complications in pediatric dialysis patients. Fifty-five children with chronic kidney disease (CKD) and seventy healthy children were genotyped for Klotho G-395A. Incidence of GA/AA genotypes and A allele were higher in ESRD patients compared with controls (54.5 vs. 7.1%, P children with GA/AA genotypes were 15.6 times more likely to develop ESRD than with GG genotype (95% CI 5.4-44.7, P disease (CVD), as carriers have 161 times higher risk of cardiovascular complications than non-carriers (95% CI 21-1233, P children with LVH, whereas G allele frequency was significantly higher among ESRD children without LVH. The A allele of the G-395A Klotho gene polymorphism shows a significantly higher frequency among children with CKD and those with CVD and LVH. This mutant allele could be used as a risk marker for the development of ESRD as well as a predictor of CVD in these children.

    This study explored the association between pubertal stage and anthropometric and cardiometabolic risk factors in youth. A cross-sectional study was conducted in 2877 Colombian children and adolescents (9–17.9 years of age). Weight, height, and waist circumference were measured and body mass index (BMI) was calculated. A biochemical study was performed to determine the cardiometabolic risk index (CMRI). Blood pressure was evaluated and pubertal stage was assessed with the Tanner criteria. Hierarchical multiple regression analyses were performed. The most significant variable (p < 0.05) in the prognosis of cardiometabolic risk was found to be the BMI in both boys and girls. In the case of girls, the pubertal stage was also a CMRI predictive factor. In conclusion, BMI was an important indicator of cardiovascular risk in both sexes. Pubertal stage was associated with cardiovascular risk only in the girls. PMID:28640231

    Monitoring of response to neoadjuvant chemotherapy (NCT) is important for optimal management of patients with breast cancer. {sup 99m}Tc-3PRGD{sub 2} SPECT is a newly developed imaging modality for evaluating tumor vascular status. In this study, we investigated the application of {sup 99m}Tc-3PRGD{sub 2} SPECT in evaluating therapy response to NCT in patients with stage II or III breast cancer. Thirty-three patients were scheduled to undergo {sup 99m}Tc-3PRGD{sub 2} SPECT at baseline, after the first and second cycle of NCT. Four patients had extremely low {sup 99m}Tc-3PRGD{sub 2} uptake at baseline, and were not included in the subsequent studies. Changes in tumor to nontumor (T/N) ratio were compared with pathological tumor responses classified using the residual cancer burden system. Receiver operator characteristic analysis was used to compare the power to identify responders between the end of the first and the end of the second cycle of NCT. The impact of breast cancer subtype on {sup 99m}Tc-3PRGD{sub 2} uptake was evaluated. The correlation between {sup 99m}Tc-3PRGD{sub 2} uptake and pathological tumor response was also evaluated in each breast cancer subtype. Surgery was performed after four cycles of NCT and pathological analysis revealed 18 responders and 15 nonresponders. In patients with clearly visible {sup 99m}Tc-3PRGD{sub 2} uptake at baseline, the sensitivity, specificity, and negative predictive value of {sup 99m}Tc-3PRGD{sub 2} SPECT were 86.7 %, 85.7 % and 86.7 % after the first cycle of NCT, and 92.9 %, 93.3 % and 93.3 % after the second cycle, respectively. Among these patients, the HER-2-positive group demonstrated both higher T/N ratios and a greater change in T/N ratio than patients with other breast cancer subtypes (P < 0.05). A strong correlation was found between changes in T/N ratio and pathological tumor response in the HER-2-positive group (P < 0.03). {sup 99m}Tc-3PRGD{sub 2} SPECT seems to be useful for determining the pathological

    Full Text Available Abstract Background Health-related quality of life (HRQOL assessment is a key component of clinical oncology trials. However, few breast cancer trials comparing adjuvant conventional radiotherapy (CR and hypofractionated tomotherapy (TT have investigated HRQOL. We compared HRQOL in stage I-II breast cancer patients who were randomized to receive either CR or TT. Tomotherapy uses an integrated computed tomography scanner to improve treatment accuracy, aiming to reduce the adverse effects of radiotherapy. Methods A total of 121 stage I–II breast cancer patients who had undergone breast conserving surgery (BCS or mastectomy (MA were randomly assigned to receive either CR or TT. CR patients received 25 × 2 Gy over 5 weeks, and BCS patients also received a sequential boost of 8 × 2 Gy over 2 weeks. TT patients received 15 × 2.8 Gy over 3 weeks, and BCS patients also received a simultaneous integrated boost of 15 × 0.6 Gy over 3 weeks. Patients completed the EORTC QLQ-C30 and BR23 questionnaires. The mean score (± standard error was calculated at baseline, the end of radiotherapy, and at 3 months and 1, 2, and 3 years post-radiotherapy. Data were analyzed by the 'intention-to-treat' principle. Results On the last day of radiotherapy, patients in both treatment arms had decreased global health status and functioning scores; increased fatigue (clinically meaningful in both treatment arms, nausea and vomiting, and constipation; decreased arm symptoms; clinically meaningful increased breast symptoms in CR patients and systemic side effects in TT patients; and slightly decreased body image and future perspective. At 3 months post-radiotherapy, TT patients had a clinically significant increase in role- and social-functioning scores and a clinically significant decrease in fatigue. The post-radiotherapy physical-, cognitive- and emotional-functioning scores improved faster in TT patients than CR patients. TT patients also had a better

    The prognosis for patients with advanced FIGO stage III epithelial ovarian cancer remains poor despite the aggressive standard treatment, consisting of maximal cytoreductive surgery and platinum-based chemotherapy. The median time to recurrence is less than 2 years, with a 5-years survival rate of -20-25%. Recurrences of the disease occur mostly intraperitoneally. Ovarian cancer is a radiosensitive tumor, so that the use of whole abdominal radiotherapy (WAR) as a consolidation therapy would appear to be a logical strategy. WAR used to be the standard treatment after surgery before the chemotherapy era; however, it has been almost totally excluded from the treatment of ovarian cancer during the past decade because of its high toxicity. Modern intensity-modulated radiation therapy (IMRT) has the potential of sparing organs at risk like kidneys, liver, and bone marrow while still adequately covering the peritoneal cavity with a homogenous dose. Our previous phase I study showed for the first time the clinical feasibility of intensity-modulated WAR and pointed out promising results concerning treatment tolerance. The current phase-II study succeeds to the phase-I study to further evaluate the toxicity of this new treatment. The OVAR-IMRT-02 study is a single-center one arm phase-II trial. Thirty seven patients with optimally debulked ovarian cancer stage FIGO III having a complete remission after chemotherapy will be treated with intensity-modulated WAR as a consolidation therapy. A total dose of 30 Gy in 20 fractions of 1.5 Gy will be applied to the entire peritoneal cavity including the liver surface and the pelvic and para-aortic node regions. Organ at risk are kidneys, liver (except the 1 cm-outer border), heart, vertebral bodies and pelvic bones.

    Purpose: To determine the factors associated with the use of radiation therapy and associated survival outcomes in early-stage marginal zone lymphoma of the mucosa-associated lymphoid tissue (MALT). Methods and Materials: We extracted data on adult patients with stage I/II MALT lymphoma diagnoses between 1998 and 2010 recorded in the Surveillance, Epidemiology, and End Results (SEER) database. We studied factors associated with radiation therapy administration in a logistic regression model and described the cumulative incidence of lymphoma-related death (LRD) according to receipt of the treatment. The association of radiation therapy with survival was explored in multivariate models with adjustment for immortal time bias. Results: Of the 7774 identified patients, 36% received radiation therapy as part of the initial course of treatment. Older patients; black or Hispanic men; white, Hispanic, and black women; and socioeconomically disadvantaged and underinsured patients had a significantly lower chance of receiving radiation therapy. Radiation therapy administration was associated with a lower chance of LRD in most sites. In cutaneous, ocular, and salivary MALT lymphomas, the 5-year estimate of LRD after radiation therapy was 0%. The association of radiation therapy with overall survival in different lymphoma sites was heterogeneous, and statistically significant in cutaneous (hazard ratio 0.45, P=.009) and ocular (hazard ratio 0.47, P<.0001) locations after multivariate adjustment. Conclusions: Demographic factors are associated with the use of radiation therapy in MALT lymphoma. Clinicians should be sensitive to those disparities because the administration of radiation therapy may be associated with improved survival, particularly in cutaneous and ocular lymphomas.

    Chronic kidney disease (CKD) is a common medical condition among children and obsessive-compulsive disorder (OCD) is a frequent, chronic, costly, and disabling disorder among them. The aim of this study was to investigate obsessive-compulsive disorder (OCD) in children with early stages of CKD, and to compare it with the occurrence of OCD in healthy children. In this case-control study, we evaluated 160 children aged 7 to 17 years old who were visited in the pediatric clinics of Amir-Kabir hospital, Arak, Iran. The control group consisted of 80 healthy children and the case group included 80 children with Stage 1 to 3 CKD. The ages and sex of the children in the two groups were matched. OCD in children was evaluated using the obsessive compulsive inventory-child version (OCI-CV). The mean scores of doubting/checking (case: 3.52 ± 2.54, control: 2.5 ± 2.32, P = 0.007) and ordering (case: 2.59 ± 1.81, control: 1.5 ± 2.56, P = 0.005) in the children with CKD was significantly higher than in the healthy ones. Moreover, the mean total scores for the OCI-CV of the children with CKD at 15.32 ± 7.69 was significantly higher than the scores of the healthy ones at 11.12 ± 2.54 (P = 0.021). There was a significant correlation between the CKD duration and doubting/checking (P = 0.004, correlation coefficient (CC): 0.4), obsessing (P = 0.06, CC: 0.02), washing (P = 0.031, CC: 0.8), ordering (P = 0.001, CC: 0.2), and the total scores of the OCI-CV questionnaire (P = 0.04, CC: 0.4). The risk of OCD in children with CKD is significantly higher than that in healthy children. Although the results seem to suggest that psychiatric intervention can be helpful in treating OCD in children with CKD, further investigation into the medical condition is required so as to obtain more definitive conclusions.

    Prominent upper front teeth are a common problem affecting about a quarter of 12-year-old children in the UK. The condition develops when permanent teeth erupt. These teeth are more likely to be injured and their appearance can cause significant distress. Children are often referred to an orthodontist for treatment with dental braces to reduce the prominence of their teeth. If a child is referred at a young age, the orthodontist is faced with the dilemma of whether to treat the patient early or to wait and provide treatment in adolescence. To assess the effects of orthodontic treatment for prominent upper front teeth initiated when children are seven to 11 years old ('early treatment' in two phases) compared to in adolescence at around 12 to 16 years old ('late treatment' in one phase); to assess the effects of late treatment compared to no treatment; and to assess the effects of different types of orthodontic braces. Cochrane Oral Health's Information Specialist searched the following databases: Cochrane Oral Health's Trials Register (to 27 September 2017), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library, 2017, Issue 8), MEDLINE Ovid (1946 to 27 September 2017), and Embase Ovid (1980 to 27 September 2017). The US National Institutes of Health Ongoing Trials Registry (ClinicalTrials.gov) and the World Health Organization International Clinical Trials Registry Platform were searched for ongoing trials. No restrictions were placed on the language or date of publication when searching the electronic databases. Randomised controlled trials of orthodontic treatments to correct prominent upper front teeth (Class II malocclusion) in children and adolescents. We included trials that compared early treatment in children (two-phase) with any type of orthodontic braces (removable, fixed, functional) or head-braces versus late treatment in adolescents (one-phase) with any type of orthodontic braces or head-braces, and trials that compared any

    Full Text Available When both parasite species are co-endemic, Plasmodium vivax incidence peaks in younger children compared to P. falciparum. To identify differences in the number of blood stage infections of these species and its potential link to acquisition of immunity, we have estimated the molecular force of blood-stage infection of P. vivax ((molFOB, i.e. the number of genetically distinct blood-stage infections over time, and compared it to previously reported values for P. falciparum.P. vivax (molFOB was estimated by high resolution genotyping parasites in samples collected over 16 months in a cohort of 264 Papua New Guinean children living in an area highly endemic for P. falciparum and P. vivax. In this cohort, P. vivax episodes decreased three-fold over the age range of 1-4.5 years.On average, children acquired 14.0 new P. vivax blood-stage clones/child/year-at-risk. While the incidence of clinical P. vivax illness was strongly associated with mol FOB (incidence rate ratio (IRR = 1.99, 95% confidence interval (CI95 [1.80, 2.19], (molFOB did not change with age. The incidence of P. vivax showed a faster decrease with age in children with high (IRR = 0.49, CI95 [0.38, 0.64] p<0.001 compared to those with low exposure (IRR = 0.63, CI95[0.43, 0.93] p = 0.02.P. vivax (molFOB is considerably higher than P. falciparum (molFOB (5.5 clones/child/year-at-risk. The high number of P. vivax clones that infect children in early childhood contribute to the rapid acquisition of immunity against clinical P. vivax malaria.

    Metabolic syndrome (MetS) is a major risk factor for cardiovascular disease and diabetes. Previous studies in obese children demonstrating a positive association between serum uric acid (sUA) and components of MetS are confounded by lack of uniformity in age and pubertal status of children. Therefore, we have examined the role of sUA in MetS and its components in pre-pubertal children (Tanner Stage I, age ≤ 9 years). Pre-pubertal obese children (32 boys, 27 girls, age 6-9 years) were recruited from Nuevo Leon, Mexico. For comparison, an equal number of children with normal body mass index (BMI) in the same age range (22 Boys, 39 girls, age 6-9 years) were also recruited from the same community. Presence of MetS and its components was defined according to the criteria of International Diabetes Federation. Fasting blood was analyzed for lipids, glucose, insulin, and uric acid. Among the obese children, sUA was positively associated with insulin resistance and hypertriglyceridemia and negatively associated with high density lipoprotein-cholesterol (HDLc). Subjects were three times more likely to have a MetS diagnosis per one unit (md/dL) difference in sUA. Of the 59 obese pre-pubertal children, 20 were classified as having MetS defined by the presence of abdominal obesity and two or more of other components described under methods. Of these, 57.1% (20/61) had sUA between 5.1 and 7.1 mg/dl. The findings of this study clearly indicate a positive relationship between uric acid and MetS and its components in pre-pubertal obese children with Tanner stage I and ≤9 years of age.

    The incidence of oropharyngeal squamous cell carcinoma (OPSCC) has markedly increased over the last three decades due to newly found associations with human papillomavirus (HPV) infection. Primary radiotherapy (RT) is the treatment of choice for OPSCC at most centers, and over the last decade, the addition of concurrent chemotherapy has led to a significant improvement in survival, but at the cost of increased acute and late toxicity. Transoral robotic surgery (TORS) has emerged as a promising alternative treatment, with preliminary case series demonstrating encouraging oncologic, functional, and quality of life (QOL) outcomes. However, comparisons of TORS and RT in a non-randomized fashion are susceptible to bias. The goal of this randomized phase II study is to compare QOL, functional outcomes, toxicity profiles, and survival following primary RT (± chemotherapy) vs. TORS (± adjuvant [chemo] RT) in patients with OPSCC. The target patient population comprises OPSCC patients who would be unlikely to require chemotherapy post-resection: Tumor stage T1-T2 with likely negative margins at surgery; Nodal stage N0-2, ≤3 cm in size, with no evidence of extranodal extension on imaging. Participants will be randomized in a 1:1 ratio between Arm 1 (RT ± chemotherapy) and Arm 2 (TORS ± adjuvant [chemo] RT). In Arm 1, patients with N0 disease will receive RT alone, whereas N1-2 patients will receive concurrent chemoradiation. In Arm 2, patients will undergo TORS along with selective neck dissections, which may be staged. Pathologic high-risk features will be used to determine the requirement for adjuvant radiotherapy +/- chemotherapy. The primary endpoint is QOL score using the M.D. Anderson Dysphagia Inventory (MDADI), with secondary endpoints including survival, toxicity, other QOL outcomes, and swallowing function. A sample of 68 patients is required. This study, if successful, will provide a much-needed randomized comparison of the conventional strategy of primary RT

    Purpose: Radiotherapy (RT) planning for breast cancer using lung density correction improves dose homogeneity. Its use obviates the need for a medial wedge, thus reducing scatter to the opposite breast. Although lung density correction is used at many centers in planning for early-stage breast cancer, long-term results of local control and survival have not been reported. Since 1984, we have used lung density correction for dose calculations at the University of Michigan. We now present our 10-year and 15-year results. Methods and Materials: The records of 867 patients with Stage I/II breast cancer treated with breast-conserving surgery and RT with or without systemic therapy were reviewed. Tangential fields delivering 45-50 Gy to the whole breast calculated using lung density correction were used. A boost was added in 96.8% of patients for a total median dose of 61.8 Gy. Results: With a median follow-up of 6.6 years (range, 0.2-18.9 years), 5-, 10-, and 15-year actuarial rates of in-breast tumor recurrence as only first failure were 2.2%, 3.6%, and 5.4%, respectively. With surgical salvage, the 15-year cumulative rate of local control was 99.7%. Factors that significantly predicted for increased rate of local recurrence in multivariate analysis were age ≤ 35 years, hazard ratio 4.8 (95% confidence interval [CI], 1.6-13.9) p = 0.004; negative progesterone receptor status, hazard ratio 6.8 (95% CI, 2.3-20.3) p = < 0.001; negative estrogen receptor status, hazard ratio 4.0 (95% CI, 1.5-11.1) p = 0.007; and lack of adjuvant tamoxifen therapy, hazard ratio 7.7 (95% CI, 1.7-33.3) p = 0.008. Relapse-free survival rates at 5, 10, and 15 years were 84.6%, 70.8%, and 55.9%, respectively; breast cancer-specific survival rates were 94.4%, 90.5%, and 86.9%, respectively; and corresponding estimates for overall survival were 89.7%, 75.7%, and 61.3%. Conclusions: Use of lung density correction was associated with high rates of local control, relapse-free survival, breast

    Full Text Available Children with chronic kidney disease are at high risk for growth retardation and decreased adult height. Growth hormone (GH treatment is known to stimulate growth in children with short stature suffering from chronic kidney disease. However, the extent to which this the-rapy affects final adult height is not known. This study was performed on 15 patients with end-stage renal disease (ESRD on regular hemodialysis to detect the effect of using recombinant human growth hormone (rhGH on growth of patients with ESRD on regular hemodialysis and compa-ring this effect with the growth velocity in the same group without using rhGH in the year before therapy. There were eight females and seven males with mean age 10.6 ± 2.8 (range 5-14 years. For each patient, recombinant GH was given for one year, three-times weekly. The data of these 15 patients was compared with the year before treatment versus data of the same group of patients after six months and after one year of rhGH therapy. Our results showed that, in the year before therapy, height of these patients increased from a mean of 112.1 ± 11.6 cm to 112.7 ± 11.5 cm, which is a non-significant increase statistically (P >0.05 as well as clinically (mean growth velocity 0.6 cm/year, while height of these patients increased from a mean of 112.7 ± 11.5 cm at the start of therapy to 116.8 ± 11 cm after therapy for one year, which, although statically not significant (P >0.05, was of clinical significance as it makes rate of increase, i.e. the mean growth velocity, 4.1 cm/year close to the normal growth velocity, which is 5 cm/year, before puberty. rhGH therapy for patients with ESRD on regular hemodialysis is helpful in height gain and catch-up growth even when given three-times per week instead of five- or six-times per week. We recommend giving
