Long-term treatment in chronic noncancer pain: Results of an observational study comparing opioid and nonopioid therapy

Background and aimsRecent studies reveal high prevalence rates of patients receiving long-term opioids. However, well designed studies assessing effectiveness with longer than 3 months follow-up are sparse. The present study investigated the outcomes of long-term opioid therapy compared to nonopioid treatment in CNCP patients with respect to measures of pain, functional disability, psychological wellbeing, and quality of life (QoL). MethodsThree hundred and thirty three consecutive patients at our pain clinic were included and divided into patients with continuous opioid treatment for at least 3 months (51%) and patients receiving nonopioid analgesics (49%). Further, outcome of different doses of opioid (<120mg vs. >120mg morphine equivalents) and differences between high and low potency opioids were examined. ResultsThe opioid and nonopioid groups did not differ with regard to pain intensity or satisfaction with analgesic. Patients with continuous opioids treatment reported higher neuropathic like pain, longer duration of pain disorder, lower functional level, wellbeing, and physical QoL in comparison to patients receiving nonopioid analgesics. Higher opioid doses were associated with male gender, intake of high potency opioids and depression but there were no differences with regard to pain relief or improvement of functional level between high and low doses. Similarly, patients on high potency opioids reported more psychological impairment than patients on low potency opioids but no advantage with regard to pain relief. Overall, remaining level of pain, functional disability and poor QoL were quite high irrespective of the analgesic used or opioid dosing. ConclusionIn the long-term no clear advantage of opioid vs. non-opioid analgesics could be revealed. In terms of remaining pain intensity, functional disability and quality of life, treatment with pain medication proved insufficient. Additionally, with higher doses of opioids the benefit to risk relationship becomes worse and patients on high potency opioids reported more psychological impairment than patients on low potency opioids but no advantage with regard to pain relief. ImplicationsOur results raise questions about the long-term effectiveness of analgesic treatment regimens irrespective of analgesics type employed and call for more multidisciplinary treatment strategies.

Apolipoprotein E4, Gender, Body Mass Index, Inflammation, Insulin Resistance, and Air Pollution Interactions: Recipe for Alzheimer's Disease Development in Mexico City Young Females.

Given the epidemiological trends of increasing Alzheimer's disease (AD) and growing evidence that exposure and lifestyle factors contribute to AD risk and pathogenesis, attention should be paid to variables such as air pollution, in order to reduce rates of cognitive decline and dementia. Exposure to fine particulate matter (PM2.5) and ozone (O3) above the US EPA standards is associated with AD risk. Mexico City children experienced pre- and postnatal high exposures to PM2.5, O3, combustion-derived iron-rich nanoparticles, metals, polycyclic aromatic hydrocarbons, and endotoxins. Exposures are associated with early brain gene imbalance in oxidative stress, inflammation, innate and adaptive immune responses, along with epigenetic changes, accumulation of misfolded proteins, cognitive deficits, and brain structural and metabolic changes. The Apolipoprotein E (APOE) 4 allele, the most prevalent genetic risk for AD, plays a key role in the response to air pollution in young girls. APOE 4 heterozygous females with >75% to <94% BMI percentiles are at the highest risk of severe cognitive deficits (1.5-2 SD from average IQ). This review focused on the relationships between gender, BMI, systemic and neural inflammation, insulin resistance, hyperleptinemia, dyslipidemia, vascular risk factors, and central nervous system involvement in APOE4 urbanites exposed to PM2.5 and magnetite combustion-derived iron-rich nanoparticles that can reach the brain. APOE4 young female heterozygous carriers constitute a high-risk group for a fatal disease: AD. Multidisciplinary intervention strategies could be critical for prevention or amelioration of cognitive deficits and long-term AD progression in young individuals at high risk.

MicroRNA-181b-5p, ETS1, and the c-Met pathway exacerbate the prognosis of pancreatic ductal adenocarcinoma after radiation therapy.

Preoperative chemoradiation therapy (CRT) for pancreatic ductal adenocarcinoma (PDAC) has emerged as a reasonable strategy that shows good prognostic impact. However, after preoperative CRT, resected specimens show remnant tumor cells, which indicate that some tumor cells had acquired or were selected for resistance to CRT. Recently, two oncological mechanisms, the EMT and the presence of CSCs, were reported to be associated with resistance in various cancers. Previous reports showed that HGF could induce EMT in PDAC cells; moreover, the HGF receptor, c‐Met, was identified as a dominant pancreatic CSC marker. However, the clinical significance of c‐Met expression remains unclear. So, we hypothesized that remnant PDAC tissue after CRT might harbor cells with high c‐Met expression, and these cells may exacerbate patients’ prognosis. In the immunohistochemical analysis, we showed that preoperative CRT was significantly associated with high c‐Met expression; moreover, high c‐Met expression was a significant marker of a dismal prognosis. Next, we investigated mechanisms of c‐Met upregulation in PDAC cells. We established GEM‐resistant and radioresistant PDAC cells to analyze the transcriptome involved in c‐Met expression. The microarray data for the established radiation‐resistant PDAC cells indicated miR‐181b‐5p downregulation, which targets ETS1, one of the transcription factors for c‐Met, and it was shown that radiation exposure induced c‐Met expression through ETS1 increase by the suppression of miR‐181b‐5p. These results suggested that targeting these mechanisms may promote the development of a novel multidisciplinary treatment strategy for improving preoperative CRT efficiency.

Appetite self-regulation: Environmental and policy influences on eating behaviors.

Appetite regulation is influenced by the environment, and the environment is shaped by food-related policies. This review summarizes the environment and policy research portion of an NIH Workshop (Bethesda, MD, 2015) titled "Self-Regulation of Appetite-It's Complicated." In this paper, we begin by making the case for why policy is an important tool in efforts to improve nutrition, and we introduce an ecological framework that illustrates the multiple layers that influence what people eat. We describe the state of the science on how policies influence behavior in several key areas: the federal food programs, schools, child care, food and beverage pricing, marketing to youth, behavioral economics, and changing defaults. Next, we propose novel approaches for multidisciplinary prevention and intervention strategies to promote breastfeeding, and examine interactions between psychology and the environment. Policy and environmental change are the most distal influences on individual-level appetite regulation, yet these strategies can reach many people at once by changing the environment in which food choices are made. We note the need for more research to understand compensatory behavior, reactance, and how to effectively change social norms. To move forward, we need a more sophisticated understanding of how individual psychological and biological factors interact with the environment and policy influences.

Retrospective analysis of the effects of systemic chemotherapy to the ovarian metastases from colorectal cancer.

731 Background: Ovarian metastases from colorectal cancers are relatively rare. Since most ovarian metastases are also associated with other metastatic sites, the prognosis is reported to be poor. It is not fully understood whether the response to systemic chemotherapy of ovarian metastases differs from that to other metastatic sites. Methods: We retrospectively reviewed the clinical data of patients with ovarian metastases from colorectal cancer treated at our hospital between January 2006 and December 2015. Results: Among the 635 female patients with relapsed or metastatic colorectal cancer, 57 (9.0%) had ovarian metastases before the first-line treatment; 37 patients received palliative chemotherapy, and 20 patients were initially treated by surgical resection. In addition, 38 cases of ovarian metastases developed after the initiation of first-line chemotherapy. Overall, 95 patients (15.0%) with ovarian metastases were treated during this period. The objective response rate for systemic chemotherapy of ovarian metastases was lower than that for other metastatic sites (22.9 % vs 60.9 % for first-line, 3.4 % vs 13.6 % for second-line, 11.1 % vs 26.6 % for third-line, and 0% vs 18.2 % for fourth-line, respectively). After the initiation of chemotherapy, surgical resection of ovarian metastases was positively associated with a longer overall survival (26.8 months for cytoreductive surgery and 17.0 months for only systemic chemotherapy, p &lt; 0.001), especially when the other metastatic sites had not progressed after chemotherapy. Conclusions: Ovarian metastases are less responsive to systemic chemotherapy compared to the extra-ovarian metastases. Our data also suggest that multi-disciplinary treatment strategy including systemic chemotherapy and cytoreductive surgery might improve the prognosis of ovarian metastases.

Sex-based differences in pain distribution in a cohort of patients with persistent post-traumatic neck pain

Objectives: To analyze a cohort of 745 consecutive patients referred to a regional specialist clinic for evaluation of post-traumatic neck pain during a five-year period.Methods: A cross-sectional observational study of baseline assessments performed by multi-professional rehabilitation teams according to a standardized checklist.Results: The cohort contained nearly twice as many females as males (64% versus 36%). The type of injury did not differ between sexes. Of the entire cohort, 38% were diagnosed with widespread pain, 50% with regional pain, and 12% with local pain. The pain distribution among the females was 43% widespread, 48% regional, and 9% local, and corresponding figures among males were 29%, 53%, and 18%. Longer time between trauma and assessment did not affect pain distribution among the men, but a tendency towards more widespread pain was observed among the women.Discussion: The importance of "female sex" as risk factor for the development of persistent pain after neck trauma needs to be discussed further. The high frequency of regional and widespread pain among patients with persistent neck pain after trauma calls for both multidisciplinary assessments and treatment strategies. The relationships between different pain distribution patterns, disability, activity, and psychological factors need to be studied further.Implications for rehabilitationPatients suffering from pain and disability after neck trauma constitute a significant proportion of patients with persistent pain.The importance of the risk factor “female sex" should be further discussed in the development of persistent pain after neck trauma.The high frequency of regional and widespread pain among patients with persistent neck pain after trauma calls both for multidisciplinary assessments and treatment strategies.The relationships between different pain distribution patterns, disability, activity, and psychological factors need to be studied further.

HIV and fatigue – is there a role for physiotherapists?

Background: Fatigue has been identified as one of the most common and most bothersome symptoms of HIV. It is prevalent at all stages of the disease, although the exact aetiology remains unclear. Yet as current treatment for HIV allow for longer, healthier lives, the management of its long-term symptoms has become important.Objectives: The purpose of this article was to review the recent research on HIV and fatigue across the life span and to describe current knowledge on the causes and treatment of fatigue in people living with HIV.Major findings: Despite great improvements in the medical management of HIV with combination antiretroviral therapy 95% of individuals infected with HIV still experience very high levels of fatigue. The causes of fatigue in HIV are multifactorial, with physiological, sociodemographic and psychological factors all playing a role. Although fatigue affects both adults and children living with HIV, there is a paucity of research on fatigue in the paediatric population.The assessment and management of fatigue is complex given the interplay between its contributing factors. However, antidepressants, exercise and relaxation techniques all hold promise in the management of HIV-related fatigue.Conclusions: Fatigue is one of the main concerns of people living with HIV. More research is needed to identify the causes of fatigue and effective treatment modalities in this population. Holistic assessment and multi-disciplinary intervention strategies are needed in order to better meet the needs of people living with HIV as they live longer, healthier lives.

Research progress of sleep status and intervention strategies in patients with nasopharyngeal carcinoma

Sleep is closely related to the process of treatment and rehabilitation in patients with nasopharyngeal carcinoma (NPC). This paper was summarized from the sleep status and its influencing factors in patients with NPC, adverse effects of sleep disorders, and intervention strategies of sleep for patients with NPC. Intervention strategies were further demonstrated through optimization of nursing strategy, improvement of time management, application of various pharmaceutical nursing, syndrome differentiation based on traditional Chinese medicine, and psychological intervention. In order to improve sleep patterns and enhance quality of life of patients with NPC, several factors such as multidisciplinary joint intervention strategies based on alien breast cancer and prostate cancer abroad; and overall consideration of cultural background, national policy, and expert teams, etc., should be proposed to explore multidisciplinary joint intervention strategies. Key words: Nasopharyngeal carcinoma; Sleep disorder; Strategy; Review

Interactive and additive influences of Gender, BMI and Apolipoprotein 4 on cognition in children chronically exposed to high concentrations of PM2.5 and ozone. APOE 4 females are at highest risk in Mexico City

Children's air pollution exposures are associated with systemic and brain inflammation and the early hallmarks of Alzheimer's disease (AD). The Apolipoprotein E (APOE) 4 allele is the most prevalent genetic risk for AD, with higher risk for women. We assessed whether gender, BMI, APOE and metabolic variables in healthy children with high exposures to ozone and fine particulate matter (PM2.5) influence cognition. The Wechsler Intelligence Scale for Children (WISC-R) was administered to 105 Mexico City children (12.32±5.4 years, 69 APOE 3/3 and 36 APOE 3/4). APOE 4v 3 children showed decrements on attention and short-term memory subscales, and below-average scores in Verbal, Performance and Full Scale IQ. APOE 4 females had higher BMI and females with normal BMI between 75–94% percentiles had the highest deficits in Total IQ, Performance IQ, Digit Span, Picture Arrangement, Block Design and Object Assembly. Fasting glucose was significantly higher in APOE 4 children p=0.006, while Gender was the main variable accounting for the difference in insulin, HOMA-IR and leptin (p<.05).Gender, BMI and APOE influence children's cognitive responses to air pollution and glucose is likely a key player. APOE 4 heterozygous females with >75% to <94% BMI percentiles are at the highest risk of severe cognitive deficits (1.5–2SD from average IQ). Young female results highlight the urgent need for gender-targeted health programmes to improve cognitive responses. Multidisciplinary intervention strategies could provide paths for prevention or amelioration of female air pollution targeted cognitive deficits and possible long-term AD progression.

Optimizing ADHD Treatment? Results of a Pilotstudy of the ADHD Selective Contract in Bremerhaven, Germany

The attention deficit hyperactivity disorder (ADHD) is associated with substantial impairment and psychiatric comorbidities. Thus, an optimized treatment is essential. In 2011, a new multidisciplinary treatment strategy (so-called Versorgungsvertrag) was contracted for the model region of Bremerhaven, Germany. This manuscript describes the results of the feasibility testing, focusing on the effects of the Versorgungsvertrag on patients' ADHD symptoms and on the treatment satisfaction of patients' kins. Patients with ADHD (4-17 years) were assessed at baseline and at 9 months follow-up. Kins documented the current symptomatology using the FBB-ADHS questionnaire on both occasions, and rated their satisfaction with the Versorgungsvertrag at follow-up. The FBB-ADHS gives information on the severity of the ADHD core symptoms (0=normal, 3=very noticeable). 69 patients (77 kins) were included. At follow-up, data from 59 patients (67 kins) were available. FBB-ADHS data of both occasions was available for 44 patients. Improvements regarding the ADHD total score (1.27 at follow-up vs. 1.59 at baseline, p=0.003) and the subdomains inattention (1.42 vs. 1.81, p=0.001) and hyperactivity (0.96 vs. 1.22, p=0.032) were documented. In the subgroup of boys (n=34), inattention (p=0.001), impulsivity (p=0.019) and the ADHD total score (p=0.002) improved, while no changes were observed in the subgroup of girls (n=10). The majority of kins (52.4 to 68.4%) rated the treatment as helpful. Our study shows improvements for the ADHD core symptoms after 9 months and a high satisfaction of kins with the treatment strategy. Due to the lack of a control group from routine care, no certain statement about the additional benefit of the treatment strategy can be made. The null effect in the subgroup of girls might be explained by the underrepresentation of girls, but the gender distribution observed in our study is commonly observed in patients with ADHD. The positive effects during the observation period should be confirmed in further studies including a control group from routine care.

The following manuscript summarizes the most important trial results of the ASCO Meeting 2015 for gastrointestinal cancers. Besides trials on perioperative treatment of esophageal-, pancreatic- and colon cancer, we will present impressive data on new therapeutic strategies such as immunotherapy in gastric-, liver and microsatellite instable colorectal cancer. The trials will be put into context by the authors.

Gallbladder cancer presenting with jaundice: Uniformly fatal or still potentially curable?

336 Background: The prognosis of patients with gallbladder cancer (GBC) who present with jaundice has historically been considered dismal, however recent Eastern literature has demonstrated that surgical resection can be associated with long-term survival. The objective of this study was to utilize a contemporary, Western, multi-institutional dataset to examine the prognostic significance of preoperative jaundice on short- and long-term outcomes after GBC resection. Methods: Patients with GBC managed surgically from 2000 to 2015 in 10 academic institutions participating in the U.S. Extrahepatic Biliary Malignancy Consortium were stratified based on the presence of preoperative jaundice (bilirubin &gt; 3 mg/ml or requiring preoperative biliary drainage). Postoperative morbidity, mortality, and overall survival were compared. Results: Of 449 patients with GBC evaluated for resection, 301 (67%) eventually underwent curative-intent resection. Resectability for cure was much lower in patients with preoperative jaundice (48% vs. 79%, p &lt; 0.001). Of 273 patients who underwent curative-intent resection and had available preoperative bilirubin levels, 53 (19%) had preoperative jaundice and were noted to have tumors of T3/4 stage (63% vs 42%, P = 0.008), with lymph node metastasis (63% vs. 41%; p = 0.014), lymphovascular invasion (68% vs 39%; p = 0.003), and R1 margins (37 vs. 9%; p &lt; 0.001). Patients with jaundice more commonly required CBD (55% vs 32%, P = 0.004), major liver (25% vs. 7%; p &lt; 0.001) and portal vein resection (8% vs. 0.5%; p = 0.006), as well as intraoperative blood transfusion (29 % vs. 11%; p = 0.002). Overall morbidity (57% vs. 38%; p = 0.031) and in-hospital mortality (7.5% vs. 1.4%; p = 0.029) rates were higher in patients with jaundice. Overall survival after curative-intent resection was worse in patients with jaundice (median 12 vs 33 months; p &lt; 0.001). Conclusions: Half of GBC patients presenting with jaundice are not resectable for cure and when they are, their 5-year survival is 12%. These patients should not be excluded from multidisciplinary treatment strategies that include surgery, however expectations should be clearly set and selection should be cautious.

Oral and Oropharyngeal Reconstruction with a Free Flap.

Extensive surgical resection of the aerodigestive track can result in a large and complex defect of the oropharynx, which represents a significant reconstructive challenge for the plastic surgery. Development of microsurgical techniques has allowed for free flap reconstruction of oropharyngeal defects, with superior outcomes as well as decreases in postoperative complications. The reconstructive goals for oral and oropharyngeal defects are to restore the anatomy, to maintain continuity of the intraoral surface and oropharynx, to protect vital structures such as carotid arteries, to cover exposed portions of internal organs in preparation for adjuvant radiation, and to preserve complex functions of the oral cavity and oropharynx. Oral and oropharyngeal cancers should be treated with consideration of functional recovery. Multidisciplinary treatment strategies are necessary for maximizing disease control and preserving the natural form and function of the oropharynx.

Efficacy of traditional Chinese medicine in treating cancer.

The morbidity associated with cancer has rapidly increased in recent years, and in the previous 5 years has had a tendency to be the leading cause of fatality compared with cardiovascular disease. Therefore, effective measures are required with an aim to reduce the incidence. Based on the results of clinical investigation, a multidisciplinary treatment strategy for cancer, which includes radiotherapy, chemotherapy, surgery, targeted therapy and immunotherapy, are prominently used in clinical practice. However, the therapies are insufficient due to multidrug resistance, adverse effects and the presence of the root of the cancer. Therefore, there is a necessity to develop more effective or adjunctive therapies for cancer prevention and treatment. Cancer is now widely recognized as a systemic humoral disease. Similarly, the function of herbal drugs is to modulate the whole body system in a more holistic way. Recently, herbal drugs have been applied to one of the efficient approaches for cancer therapy. Furthermore, there is evidence that various herbal medicines have been proven to be useful and effective in sensitizing the conventional agents against the various factors at the cellular and molecular levels that are associated with the occurrence of cancer and in prolonging survival time, alleviating side effects of chemotherapy and radiotherapy and improving the quality of life in cancer patients.

Adherens junctions associated protein 1 serves as a predictor of recurrence of squamous cell carcinoma of the esophagus.

Esophageal squamous cell carcinoma (ESCC), the most common esophageal cancer in East Asia, is among the six cancers with the highest fatality rates worldwide. Unfortunately, multidisciplinary treatment strategies have not achieved satisfactory outcomes. Therefore, novel insights into the molecular biology of ESCC are required to improve treatment. The gene encoding the transmembrane adherens junctions-associated protein-1 (AJAP1) expressed by epithelial cells resides in chromosome 1p36, which is frequently lost or epigenetically silenced in several malignancies. Here, we investigated the expression levels and regulatory mechanism of AJAP1 transcription. We determined the levels of AJAP1 mRNA and the genes encoding potentially interacting proteins expressed by ESCC cell lines, as well as the chromosomal copy number of AJAP1 and the methylation status of its promoter region. AJAP1 mRNA levels of 78 pairs of surgically resected specimens were determined to evaluate the association of AJAP1 expression and clinicopathological factors. Nine ESCC cell lines differentially expressed AJAP1 mRNA, and demethylation of hypermethylated AJAP1 genomic DNA reactivated AJAP1 mRNA expression. The copy number of sequences upstream or downstream of the AJAP1 transcriptional start site was not detectably altered. AJAP1 mRNA levels correlated inversely with those of ezrin (EZR) and were significantly lower in ESCC tissues compared with adjacent normal tissues. AJAP1 mRNA levels decreased gradually with increasing tumor stage. Patients with downregulated AJAP1 transcription were more likely to experience shorter overall and disease-free survival. Multivariate analysis of disease-free survival identified downregulated AJAP1 transcription as an independent prognostic factor. These results suggest that in ESCC, AJAP1 acts as a putative tumor suppressor and that AJAP1 transcription is regulated by promoter hypermethylation. These findings indicate that downregulated AJAP1 transcription may serve as a novel tumor biomarker to predict recurrence of ESCC after esophagectomy.

Cervical radiculitis presenting as shoulder pain

Background: Although cervical radiculitis is a well-known cause of referred shoulder pain, there is little information concerning its frequency and treatment. Methods: Retrospective review of the records of all new patients presenting to a single orthopaedic shoulder surgeon at a tertiary referral center from 2009 to 2012 identified 1169 patients with a chief complaint of shoulder pain; 60 (4%) with an isolated diagnosis of cervical radiculitis were included in the study; 48 were available for follow-up evaluation. If conservative therapy failed, MRI was done, followed by cervical epidural corticosteroid injection by a physiatrist (11 patients); three with persistent symptoms had anterior cervical fusion. Visual analog pain scores (VAS) were recorded at the initial visit, and VAS and National Disability Index Questionnaire (NDIQ) scores were obtained at a minimum of 1 yr. Results: Of 1169 patients with a chief complaint of shoulder pain, 60 (4%) were diagnosed with isolated cervical radiculitis. Of 48 available for follow-up evaluation, 34 were treated conservatively, 11 had cervical epidural injections, and three required anterior cervical discectomy and fusion (ACDF). At mean follow-up of 27 mo, the average overall pain score was 2 compared to 5.2 at the initial visit (P<0.0001). The differences between initial and follow-up VAS scores demonstrated improvements with all three treatments. Fifteen patients reported no disability, and 32 reported minimal disability. Conclusions: These findings suggest that, if correctly diagnosed and treated, patients with cervical radiculitis presenting as shoulder pain can obtain marked reductions in pain and disability with a step-wise multidisciplinary treatment strategy.

Porphyrin Derivatives-Mediated Sonodynamic Therapy for Malignant Gliomas In Vitro

Because it is highly infiltrative, malignant glioma is a cancer with a poor prognosis despite multidisciplinary treatment strategies, such as aggressive surgery and chemoradiotherapy, necessitating new therapeutic approaches to control migration of tumor cells. In our study, we investigated the efficacy of sonodynamic therapy of glioma cells in vitro using porphyrin derivatives, including 5-aminolevulinic acid, protoporphyrin IX and talaporfin sodium, as sonosensitizers. These substances have been known to accumulate in glioma cells and are expected to have cytotoxic effects on sonication. Our study found that the cytotoxicity of sonication of glioma cells is enhanced by each sonosensitizer and that the efficacy of sonodynamic therapy may depend on the degree of intracellular accumulation of sonosensitizer. Also, the study suggests that induction of apoptosis is a major mechanism underlying cell death. Though further investigations are necessary, our preliminary result indicates a potential for sonodynamic therapy with sonosensitizers in glioma treatment.
