The role of transoral robotic surgery in the management of oropharyngeal cancer

Purpose of review The rising incidence of oropharyngeal squamous cell carcinoma (OPSCC), in large part as a result of the human papillomavirus (HPV), has driven a movement for the change in the management strategies. Renewed interest in minimally invasive approaches of endoscopic head and neck surgery led to introduction of transoral surgery, including transoral robotic surgery (TORS). Recent findings Several recent studies, based on large multi-institutional studies and systematic reviews of the literature, have shown excellent oncologic and functional outcomes with TORS for OPSCC. Also, a growing amount of clinical evidence supports the use of TORS in the management of carcinoma of unknown primary site and in selected patients with recurrent OPSCC with acceptable oncologic and better functional outcomes in comparison with traditional surgical approaches. Comparative studies with other therapeutic modalities (conventional surgical and nonsurgical) showed that TORS can be used to treat OPSCC, reducing morbidity and treatment costs, while providing equivalent oncologic results. Summary Large and robust data available in the literature supports the role of TORS within the multidisciplinary treatment paradigm for the management of OPSCC. Information from ongoing randomized clinical trials comparing TORS with and without dose-reduced radiotherapy or with and without intensified adjuvant treatment for high-risk OPSCC patients is necessary to determine the role of de-escalation of therapy in the era of HPV and OPSCC.
Endotoxin recognition in fish results in inflammatory cytokine secretion not gene expression

Macrophages are phagocytes that have a central role in the organization of the immune system after an infection. These cells can recognize specific molecular components of micro-organisms (pathogen-associated molecular patterns, PAMPs) via specific receptors (PRRs) and elicit specific cellular responses. In the past, the expression of immune genes in response to different PAMPs has been characterized in different fish species. However, little is known about actual cytokine release. We characterized the secretion of tumour necrosis factor (TNF)-α in primary macrophage cultures of rainbow trout (Oncorhynchus mykiss) in response to several PAMPs by Western blot and compared this to the induction of TNF-α gene expression as well as other pro-inflammatory cytokines such as interleukin (IL)-1β and IL-6 and anti-viral molecules such as INF-α and Mx protein (Mx). We show that lipopolysaccharide (LPS) and zymosan are major inducers of TNF-α secretion, which is not initially linked to the induction of TNF-α mRNA expression. The secretion of TNF-α, but intriguingly not the expression, is also stimulated by ultrapure LPS meaning that, in fish, contaminants of commercial LPS preparations are better inducers of the inflammatory response. Moreover, we have characterized the signaling pathways that are activated by different PAMPs and the link between those pathways and the final step of TNF-α secretion: TNF-α shedding by TNF-α converting enzyme (TACE/ ADAM17). For the first time, we show that, in fish macrophages, TNF-α is processed by TACE-like activity and this cleavage is dependent upon the activation of ERK, p38MAPK and JNK signaling pathways by LPS.
Prognosis of Cerebral Vein and Dural Sinus Thrombosis: Results of the International Study on Cerebral Vein and Dural Sinus Thrombosis (ISCVT)

Background and Purpose— The natural history and long-term prognosis of cerebral vein and dural sinus thrombosis (CVT) have not been examined previously by adequately powered prospective studies. Methods— We performed a multinational (21 countries), multicenter (89 centers), prospective observational study. Patients were followed up at 6 months and yearly thereafter. Primary outcome was death or dependence as assessed by modified Rankin Scale (mRS) score >2 at the end of follow-up. Results— From May 1998 to May 2001, 624 adult patients with CVT were registered. At the end of follow-up (median 16 months), 356 patients (57.1%) had no symptom or signs (mRS=0), 137 (22%) had minor residual symptoms (mRS=1), and 47 (7.5%) had mild impairments (mRS=2). Eighteen (2.9%) were moderately impaired (mRS=3), 14 (2.2%) were severely handicapped (mRS=4 or 5), and 52 (8.3%) had died. Multivariate predictors of death or dependence were age >37 years (hazard ratio [HR]=2.0), male sex (HR=1.6), coma (HR=2.7), mental status disorder (HR=2.0), hemorrhage on admission CT scan (HR=1.9), thrombosis of the deep cerebral venous system (HR=2.9), central nervous system infection (HR=3.3), and cancer (HR=2.9). Fourteen patients (2.2%) had a recurrent sinus thrombosis, 27 (4.3%) had other thrombotic events, and 66 (10.6%) had seizures. Conclusions— The prognosis of CVT is better than reported previously. A subgroup (13%) of clinically identifiable CVT patients is at increased risk of bad outcome. These high-risk patients may benefit from more aggressive therapeutic interventions, to be studied in randomized clinical trials.
Effect of Temperature on the Fitness of a Vip3A Resistant Population of Heliothis virescens (Lepidoptera: Noctuidae)

ABSTRACT Microbial insecticides derived from the soil bacterium Bacillus thuringiensis (Bt) have become increasingly important for pest management. In addition to crystal (Cry) insecticidal protein toxins formed during sporulation, vegetative insecticidal protein (Vip) toxins can be produced during the vegetative phase. Resistance to Cry toxins has been reported in laboratory- and field-selected populations of various Lepidoptera species and several studies have identified fitness costs associated with Cry toxin resistance. Here, fitness costs are examined in the first insect population to be reported with resistance to a Vip toxin, a laboratory-selected Vip3A-resistant subpopulation of the tobacco budworm, Heliothis virescens (L.) (Vip-Sel). The Vip-Sel population showed reduced survival to adult eclosion compared with an unselected subpopulation at all test temperatures, including the culture temperature (25°C). Vip3A resistance was also associated with reduced egg viability and mating success and a lower intrinsic rate of population increase (rm) at temperatures below (20°C) and above (30°C) the optimal laboratory culture temperature. The latter findings agree with previous studies, that fitness costs associated with resistance are usually greater under stressful conditions. Such data can help predict the impact of fitness costs on the rate of development of resistance in the field and in the development of resistance management strategies that more fully exploit fitness costs.
Prostatitis and male pelvic pain syndrome: diagnosis and treatment.

BACKGROUND The prostatitis syndrome is a multifactorial condition of largely unknown etiology. The new NIH classification divides the prostatitis syndrome into a number of subtypes: acute bacterial prostatitis, chronic bacterial prostatitis, inflammatory and noninflammatory chronic pelvic pain syndrome, and asymptomatic prostatitis. METHODS This article is based on a selective review of the literature regarding the assessment and management of the prostatitis syndrome and on a recently published consensus statement of the International Prostatitis Collaboration Network. RESULTS Pathogenic organisms can be cultured only in acute and chronic bacterial prostatitis. These conditions should be treated with antibiotics, usually fluoroquinolones, for an adequate period of time. 90% of patients with prostatitis syndrome, however, suffer not from bacterial prostatitis but from chronic (abacterial) prostatitis / chronic pelvic pain syndrome (CP/CPPS). It remains unclear whether CP/CPPS is of infectious origin, and therefore the utility of a trial of antimicrobial treatment is debatable. Treatment with alpha receptor blockers is recommended if functional subvesical obstruction is documented or suspected. Symptomatic therapy for pelvic pain should be given as well. CONCLUSIONS The prostatitis syndrome is a complex condition with a tendency toward chronification. It is important, therefore, that the patient be fully informed about the diagnostic uncertainties and the possibility that treatment may meet with less than complete success.

The relationship of cervical lymph node metastases to primary sites of carcinoma of the upper aerodigestive tract: a pathological study.

BACKGROUND Therapeutic and elective dissection of the neck is accepted management in the treatment of squamous cell carcinoma (SCC) of the upper aerodigestive tract (UADT). Accurate histological assessment of the levels of involvement of cervical metastatic spread from different sites within the UADT has allowed the increasing use of less than radical procedures, with associated reduced morbidity. METHODS A total of 168 necks in 126 patients were examined pathologically. All levels were identified at surgery, marked and oriented by pinning the specimen to a cork board, and examined histologically. A total of 114 necks had a comprehensive neck dissection (CND) in which all levels were dissected. The number and level of involvement and the occult rate (114 necks) for each primary site was assessed. Of the total of 168 necks, 80 had pathologically involved nodes, and the number with greater than one node involved (N2b) was compared for each primary site. The number with extracapsular spread for each nodal staging was also examined. RESULTS The sites of primary SCC were the oral cavity, oropharynx, hypopharynx, supraglottic and glottic larynx. In those patients with a primary in the oral cavity, no patient had level 5 involvement, but in two patients (7%) level 4 was involved. In the oropharynx, level 1 and 5 were involved in two patients (11%) each. In the hypopharynx, level 1 was not involved in any patient, however, level 5 contained metastasis in 7 (23%). In the supraglottic larynx, level 1 was involved in one (4%) patient and level 5 was involved in three (11%). In the glottis only one patient had bilateral multiple nodes which included level 5. In no case was level 5 involved without positive nodes in other levels. The occult rate for each primary site was 45%, 22%, 77%, 54% and 29%, respectively. The multiple node rate in the 80 necks with positive nodes was, respectively, 31%, 54%, 66%, 45% and 40%. All patients with a node larger than 3 cm had extracapsular spread of tumour. CONCLUSIONS The level of nodal involvement and therefore the type of neck dissection should be determined by the site of the primary within the UADT and the presence or absence of nodes at surgery. There is a high number (39-66%) of pathologically involved necks which have multiple nodes and also nodes with extracapsular spread of tumour, which may influence the decision for postoperative radiotherapy.
Characterizing the torque lookup table of an IPM machine for automotive application

Motor drive technologies are being incorporated into the EV and HEV automobiles with ever increasing speed. With the output torque to be the main control target, various control algorithms are developed that aim to achieve high torque accuracy while maximizing the machine energy efficiency. Most of such control algorithms entail procedures to characterize the machine under control. This paper documents a detailed, industrially practical procedure of characterizing the torque lookup table for interior permanent magnet (IPM) synchronous machines. The characterized lookup table can be utilized in open-loop torque control algorithms, and is verified to achieve high torque control accuracy and suitable for torque control of IPM in automotive applications.

Outcomes of Solid Organ Transplant Recipients With Preexisting Malignancies in Remission: A Systematic Review and Meta-Analysis

Background Solid organ transplant recipients (SOTR) with a pretransplant malignancy (PTM) are at increased risk for cancer recurrence. However, it is unclear whether differences in survival and incidence of posttransplant de novo malignancies exist between recipients with PTM and those without PTM. We designed a systematic review to synthesize all available evidence assessing these outcomes. Methods A systematic search was performed in MEDLINE, EMBASE, and Cochrane Library to identify studies comparing the following outcomes in SOTR by PTM status: (1) all-cause mortality, (2) cancer-specific mortality, and (3) incidence of posttransplant de novo malignancy. Risk of bias was assessed using the Newcastle-Ottawa Scale. Results Thirty-two cohort studies were included. Recipients with PTM were at increased risk of all-cause mortality compared to recipients without PTM (pooled hazard ratio [HR], 1.51; 95% confidence interval [CI], 1.27-1.81). Similarly, recipients with PTM were 3 times more likely to die of cancer (pooled HR, 3.13; 95% CI, 2.29-4.27). The pooled HR for developing posttransplant de novo malignancy was also increased (HR, 1.92; 95% CI, 1.52-2.42). The association of all-cause mortality and SOTR with PTM did not vary by transplanted organ. Conclusions Pretransplant malignancy is associated with increased risk of all cause-mortality, cancer-specific mortality and of developing de novo malignancies after transplantation compared with those without PTM. These results reaffirm the need for careful selection of transplant recipients with PTM. Tailored screening and management strategies should be developed for this group of patients.
Lymphokine-mediated inhibition of Chlamydia replication in mouse fibroblasts is neutralized by anti-gamma interferon immunoglobulin

Experiments were carried out to characterize immunologically mediated chlamydial persistence in cell culture. Mouse fibroblasts were activated to restrict Chlamydia psittaci 6BC replication by including mitogen (concanavalin A)-induced spleen cell supernatant fluids from immunized animals in the growth medium. When mouse fibroblasts were incubated with lymphokine for 24 h before infection and then with growth medium after infection (preinfection treatment), chlamydial replication was delayed but eventually detected. No substantial chlamydial growth occurred, even with extended incubation times when mouse fibroblasts were continuously exposed to lymphokine before and after infection. Low levels of infectious chlamydiae were produced in preinfection-treated mouse fibroblasts but not in mouse fibroblasts subjected to continuous lymphokine exposure. Incubation of lymphokine with anti-murine gamma interferon immunoglobulin neutralized the observed lymphokine-mediated activity, but incubation in the presence of anti-murine alpha plus beta interferon serum did not alter lymphokine activity. We conclude that the lymphokine components responsible for activating fibroblasts to restrict C. psittaci replication exhibits properties similar to gamma interferon.
Recursos y consecuencias de cuidar a las personas mayores de 65 años: Una revisión sistemática

Introduccion: El cuidado prestado por los cuidadores principales de personas mayores constituye el principal soporte que estas reciben. Proporcionar estos cuidados afecta de diferente manera a cada cuidador. La literatura es amplia y extensa al describir estas repercusiones de la tarea de cuidar sobre el cuidador, asi como en referencia a los recursos de apoyo utilizados. Metodo: Se ha realizado una revision sistematica de la literatura, en las principales bases de datos nacionales e internacionales, sobre las intervenciones, recursos y repercusiones de la tarea de cuidar sobre los cuidadores informales de personas mayores. Conclusiones: Los cuidadores informales espanoles de personas mayores parecen disponer de diferentes recursos de apoyo en su tarea de cuidado, aunque sigue siendo la familia la principal fuente de ayuda frente a los sistemas formales. La literatura recoge repercusiones tanto positivas como negativas derivadas de la responsabilidad del cuidado. Entre estos ultimos, encontramos como maximo exponente los estados ansioso-depresivos, asi como la sobrecarga del cuidador. Sin embargo, estas consecuencias negativas se entrelazan e interactuan con las afectaciones positivas. La revision realizada nos invita a afirmar que se precisa el desarrollo de mas estudios para tratar de esclarecer la relacion entre ambos polos de la experiencia del cuidado.
Autopsy results after surgery for non-small cell lung cancer.

OBJECTIVE To determine the percentage of metastatic and unexpected residual lung cancer at autopsy in patients considered for curative resection of non-small cell lung cancer during a time when computed tomography was available as a preoperative staging tool. MATERIAL AND METHODS Clinical data and surgical and autopsy slides of all patients who underwent curative resection of nonsmall cell lung cancer at the Mayo Clinic in Rochester, Minn, between 1985 and 1999 and who underwent autopsy within 30 days of surgery were reviewed retrospectively for the presence of residual or metastatic disease. RESULTS The study group consisted of 25 men and 7 women, with a mean age of 70 years. A pulmonary metastasis was identified at surgery in 1 patient (3%). Metastases were found in an additional 5 patients (16%) at autopsy, 1 of whom had 2 sites involved. These sites included the liver in 2 and lung, epicardium, adrenal gland, and kidney in 1 each. The average diameter of metastases was 1.6 cm. No factor studied was found to be significantly associated with the presence of unrecognized metastatic disease at autopsy. CONCLUSION The advent of computed tomography as a staging tool has decreased the percentage of patients with undiagnosed metastatic disease at surgery; however, preoperative understaging in lung cancer remains a problem.
Female reproductive strategies, paternity and community structure in wild West African chimpanzees

Although the variability and complexity of chimpanzee behaviour frustrates generalization, it is widely believed that social evolution in this species occurs in the context of the recognizable social group or community. We used a combination of field observations and noninvasive genotyping to study the genetic structure of a habituated community of 55 wild chimpanzees, Pan troglodytes verus, in the Taï Forest, Côte d'Ivoire. Pedigree relationships in that community show that female mate choice strategies are more variable than previously supposed and that the observed social groups are not the exclusive reproductive units. Genetic evidence based on nuclear microsatellite markers and behavioural obser-vations reveal that females in the Taï forest actively seek mating partners outside their social unit; noncommunity males accounted for half the paternities over 5 years. This female mating strategy increases male gene flow between communities despite male philopatry, and negates the predicted higher relatedness among community males. Kin selection seems unlikely to explain the frequent cooperation and sharing observed among group males in this population. Similarly, inbreeding avoidance is probably not the sole cause of permanent adolescent female dispersal as a combination of extragroup mating and avoidance of incest with home group males would allow females to avoid inbreeding without the hazards associated with immigration into a new community. Extragroup mating as part of chimpanzee females' reproductive strategy may allow them to choose from a wider variety and number of males, without losing the resources and support provided by their male social group partners.

Impact of climate and landuse variability based on dengue epidemic outbreak in Subang Jaya

Dengue disease has continually been a major public health problem in Malaysia. The numbers of cases have risen yearly and it had become more serious in the early of 21st century. Therefore, effort to reduce the number incidences must be taken seriously and should be supported from various agencies. Concerted effort from various agencies is vital effectively manage the dengue problem. Despite all of the effort taken by the Ministry of Health in fighting dengue in Malaysia, the numbers of cases have risen yearly and it had become more serious in the early 21st century. Subang Jaya was chosen due to its highly reported dengue cases year by year. Meteorological data and landuse pattern being consolidated using GIS software and its components as an analytical tool. As a results, weather variables including relative humidity, temperature and precipitation have significant correlation with confirmed dengue cases distribution; Rainfall (t = 0.750**), (t−1=0.649**), (t−2=0.430**). For temperature (t = −0.405**), (t−1= −0.414**), (t−2= − 0.485**). As for relative humidity, the correlation is not continuously significant throughout the year 2006 until 2010 but still have good correlation weightage in 2006 for (t−1 = 0.662**). In line with that, hotspot identification of dengue cases map was fabricated by clustering pattern analysis. So, it will benefit the decision makers as well as the planning actors in just not to concentrating on the current conventional method in controlling dengue occurrence but also to better understand other contributing factors which statistically proved to have correlation with the dengue cases distribution number in Subang Jaya.
