[(18)F]FDG-PET/CT metabolic parameters as useful prognostic factors in cervical cancer patients treated with chemo-radiotherapy.
To compare the prognostic value of different anatomical and functional metabolic parameters determined using [(18)F]FDG-PET/CT with other clinical and pathological prognostic parameters in cervical cancer (CC).
Thirty-eight patients treated with standard curative doses of chemo-radiotherapy (CRT) underwent pre- and post-therapy [(18)F]FDG-PET/CT. [(18)F]FDG-PET/CT parameters including mean tumor standardized uptake values (SUV), metabolic tumor volume (MTV) and tumor glycolytic volume (TGV) were measured before the start of CRT. The post-treatment tumor metabolic response was evaluated. These parameters were compared to other clinical prognostic factors. Survival curves were estimated by using the Kaplan-Meier method. Cox regression analysis was performed to determine the independent contribution of each prognostic factor.
After 37 months of median follow-up (range, 12-106), overall survival (OS) was 71 % [95 % confidence interval (CI), 54-88], disease-free survival (DFS) 61 % [95 % CI, 44-78] and loco-regional control (LRC) 76 % [95 % CI, 62-90]. In univariate analyses the [(18)F]FDG-PET/CT parameters unfavorably influencing OS, DFS and LRC were pre-treatment TGV-cutoff ≥562 (37 vs. 76 %, p = 0.01; 33 vs. 70 %, p = 0.002; and 55 vs. 83 %, p = 0.005, respectively), mean pre-treatment tumor SUV cutoff ≥5 (57 vs. 86 %, p = 0.03; 36 vs. 88 %, p = 0.004; 65 vs. 88 %, p = 0.04, respectively) and a partial tumor metabolic response after treatment (9 vs. 29 %, p = 0.0008; 0 vs. 83 %, p < 0.0001; 22 vs. 96 %, p < 0.0001, respectively). After multivariate analyses a partial tumor metabolic response after treatment remained as an independent prognostic factor unfavorably influencing DFS and LRC (RR 1:7.7, p < 0.0001, and RR 1:22.6, p = 0.0003, respectively) while the pre-treatment TGV-cutoff ≥562 negatively influenced OS and DFS (RR 1:2, p = 0.03, and RR 1:2.75, p = 0.05).
Parameters capturing the pre-treatment glycolytic volume and metabolic activity of [(18)F]FDG-positive disease provide important prognostic information in patients with CC treated with CRT. The post-therapy [(18)F]FDG-PET/CT uptake (partial tumor metabolic response) is predictive of disease outcome
Semi-Annual Report to Congress for the Period of April 1, 2009 to September 30, 2009
[Excerpt] I am pleased to submit this Semiannual Report to Congress, which highlights the most significant activities and accomplishments of the U.S. Department of Labor, Office of Inspector General (DOL-OIG), for the six-month period ending September 30, 2009. During this reporting period, our investigative work led to 214 indictments, 221 convictions, and 7.4 million in payroll taxes. Because of our investigative expertise, the OIG is a member of the International Organized Crime (IOC) strategy headed by the U.S. Attorney General. The IOC is committed to combating crime by international organized groups.
Finally, I would like to express my sincere gratitude to former DOL Inspector General Gordon S. Heddell, who is now serving as the Inspector General at the U.S. Department of Defense. During his leadership of more than eight years, the DOL-OIG consistently achieved significant results similar to those presented in this report. As Acting Inspector General, I look forward to continuing to work with the Secretary of Labor and her management team in ensuring the effectiveness of DOL in delivering services and protecting the rights and benefits of American workers and retirees
Fuzzy-logic-based control, filtering, and fault detection for networked systems: A Survey
This paper is concerned with the overview of the recent progress in fuzzy-logic-based filtering, control, and fault detection problems. First, the network technologies are introduced, the networked control systems are categorized from the aspects of fieldbuses and industrial Ethernets, the necessity of utilizing the fuzzy logic is justified, and the network-induced phenomena are discussed. Then, the fuzzy logic control strategies are reviewed in great detail. Special attention is given to the thorough examination on the latest results for fuzzy PID control, fuzzy adaptive control, and fuzzy tracking control problems. Furthermore, recent advances
on the fuzzy-logic-based filtering and fault detection problems are reviewed. Finally, conclusions are given and some possible future research directions are pointed out, for example, topics on two-dimensional networked systems, wireless networked control systems, Quality-of-Service (QoS) of networked systems, and fuzzy access control in open networked systems.This work was supported in part by the National Natural Science Foundation of China under Grants 61329301,

Views and Experiences of New Zealand Women with Gestational Diabetes in Achieving Glycaemic Control Targets: The Views Study
Introduction. Optimal glycaemic control in women with gestational diabetes mellitus (GDM) reduces maternal and infant morbidity. Method. A survey was administered to women diagnosed with GDM to explore their views and experiences in achieving optimal glycaemic control. Results. Sixty women participated. Enablers included being taught to test capillary blood glucose in group settings where the health professional demonstrated this on themselves first (60, 100%); health professionals listening (41, 68%); being reminded to perform blood glucose testing (33, 55%); and being provided healthy meals by friends and family (28, 47%). Barriers included not having information in a woman’s first language (33, 55%); being offered unhealthy food (19, 31%); not being believed by health professionals (13, 21%); receiving inconsistent information by health professionals (10, 16%); never being seen twice by the same health professional (8, 13%); and long waiting hours at clinics (7, 11%). Two-thirds of women (37, 62%) reported that food costs were not a barrier, but that they were always or frequently hungry. Conclusion. Optimising experiences for women with GDM for achieving glycaemic control and overcoming barriers, regardless of glycaemic targets, requires further focus on providing meaningful health literacy and support from health professionals, family, friends, and work colleague
Pain sensitivity and observer perception of pain in individuals with autistic spectrum disorder
The peer-reviewed literature investigating the relationship between pain expression and perception of pain in individuals with ASD is sparse. The aim of the present systematic PRIMSA review was twofold: first, to see what evidence there is for the widely held belief that individuals with ASD are insensitive to pain or have a high pain threshold in the peer-reviewed literature and, second, to examine whether individuals with ASD react or express pain differently. Fifteen studies investigating pain in individuals with ASD were identified. The case studies all reported pain insensitivity in individuals with ASD. However, the majority of the ten experimental studies reviewed indicate that the idea that individuals with ASD are pain insensitive needs to be challenged. The findings also highlight the strong possibility that not all children with ASD express their physical discomfort in the same way as a neurotypical child would (i.e., cry, moan, seek comfort, etc.) which may lead caregivers and the medical profession to interpret this as pain insensitivity or incorrectly lead them to believe that the child is in no pain. These results have important implications for the assessment and management of pain in children with ASD
Traffic management by using admission control methods in multiple node IMS network
The paper deals with Admission Control methods (AC) as a possible solution for traffic management in IMS networks (IP Multimedia Subsystem) - from the point of view of an efficient redistribution of the available network resources and keeping the parameters of Quality of Service (QoS). The paper specifically aims at the selection of the most appropriate method for the specific type of traffic and traffic management concept using AC methods on multiple nodes. The potential benefit and disadvantage of the used solution is evaluated
Hippocampal sclerosis affects fMR-adaptation of lyrics and melodies in songs
Songs constitute a natural combination of lyrics and melodies, but it is unclear whether and how these two song components are integrated during the emergence of a memory trace. Network theories of memory suggest a prominent role of the hippocampus, together with unimodal sensory areas, in the build-up of conjunctive representations. The present study tested the modulatory influence of the hippocampus on neural adaptation to songs in lateral temporal areas. Patients with unilateral hippocampal sclerosis and healthy matched controls were presented with blocks of short songs in which lyrics and/or melodies were varied or repeated in a crossed factorial design. Neural adaptation effects were taken as correlates of incidental emergent memory traces. We hypothesized that hippocampal lesions, particularly in the left hemisphere, would weaken adaptation effects, especially the integration of lyrics and melodies. Results revealed that lateral temporal lobe regions showed weaker adaptation to repeated lyrics as well as a reduced interaction of the adaptation effects for lyrics and melodies in patients with left hippocampal sclerosis. This suggests a deficient build-up of a sensory memory trace for lyrics and a reduced integration of lyrics with melodies, compared to healthy controls. Patients with right hippocampal sclerosis showed a similar profile of results although the effects did not reach significance in this population. We highlight the finding that the integrated representation of lyrics and melodies typically shown in healthy participants is likely tied to the integrity of the left medial temporal lobe. This novel finding provides the first neuroimaging evidence for the role of the hippocampus during repetitive exposure to lyrics and melodies and their integration into a song
“Backdoor to Eugenics”?: the Risks of Prenatal Diagnosis for Poor, Black Women
This article is situated at the intersection of three of the conference’s stated subject areas: Race and Healthcare, Reproductive Rights, and Race and the Family. My recent research has focused on the manner in which pregnant women who learn of fetal genetic abnormalities prenatally receive counseling as they decide whether to terminate or bring their fetuses to term. The decision whether to terminate on genetic grounds is particularly vexing because it often turns on speculative medical information, and it can result in elevated rates of grief, depression, and post-traumatic stress. Though the prenatal genetic counseling offered to expectant women learning of a fetal abnormality exists ostensibly to provide them with objective information rather than to encourage or discourage pregnancy terminations, the reality is that such counseling is often coercive in the direction of aborting genetic anomalous fetuses. Because genetic counseling tends to consider family factors such as wealth and perceived preparedness to raise a child with a persistent medical condition or disability—and because the vast majority of genetic counselors are highly educated white women—the pro-termination norms of prenatal genetic counseling disproportionately impact nonwhite, non-affluent pregnancies. This observation is consistent with prior state and private practices aimed at controlling black reproduction. Because the detection of prenatal genetic abnormalities will soon rise sharply due to advances in technology and increased access to prenatal genetic analysis under the Patent Protection and Affordable Care Act, far more poor, black pregnant women will receive genetic counseling that will make them more likely to abort their fetuses in future years. This article describes the scale and scope of this potentially far- reaching problem and offers suggestions for how to eliminate racial and class bias in prenatal genetic counseling
