The available studies indicate that AfB1 impairs the reproductive performance of females hair loss cure 51 cheap finpecia 1mg fast delivery, resulting in adverse effects on sexual maturation hair loss while breastfeeding discount finpecia 1mg, growth and maturation of the follicles hair loss cure boots order finpecia 1mg fast delivery, levels of hormones bio herbal anti-hair loss cheap finpecia 1 mg without a prescription, gestation and growth of the fetus (Gupta hair loss zyprexa buy generic finpecia 1mg, 2011) hair loss cure israel finpecia 1mg discount. Male reproductive toxicity studies with aflatoxins in vivo and in vitro have reported testicular degeneration and decreased sperm production (Gupta, 2011). In a related study, decreased conception rate and litter size, and increases in fetal resorption and implantation loss were seen in rats gavaged with AfB1 at 7. Alternatively, the observations on day 8 may reflect factors other than AfB1 exposure. However, no threshold for 78 immunotoxicity has been defined for any species (Williams et al. The primary immunosuppressive effect of aflatoxins is on cell-mediated immunity, particularly delayed-type hypersensitivity. Aflatoxins were also reported to reduce antibody titers to some infectious bacteria in rabbits (Williams et al. Aflatoxin has also been shown to reduce phagocytic activity in rabbit alveolar macrophages and to inhibit phagocytic cell function in normal peripheral blood monocytes in vitro (Williams et al. Results from these studies indicate that AfB1 is a very potent carcinogen in many species, including nonhuman primates and rodents. The main target organ for carcinogenicity is the liver, causing hepatocellular carcinomas in rats. This conjugation is important in reducing the tumor burden in experimental animals. It is also suggested that the formation of reactive oxygen species and lipid peroxidation also play a major role in aflatoxin toxicity (Ezekiel et al. Although the effects in humans are consistent with those seen in experimental animals, data on effect levels in humans is limited. Aflatoxins are primary skin irritants (Joffe and Ungar, 1969), but data were not available on the potential of aflatoxins to cause skin sensitization. There are no standard reproductive or developmental toxicity studies for the aflatoxins. Although malformations were also seen at high parenteral doses, the reliability of the report is low. Dose-response data are limited, but effects were seen in mice at an oral dose of 0. AfB1 is a potent liver carcinogen in a number of animal species, although wide species variability exists. It causes liver tumors in mice, rats, fish, marmosets and monkeys following administration by various routes. These differences have been attributable to the differences in activation and detoxification activities of the aflatoxin-metabolizing enzymes. The Toxicology of Aflatoxins: Human Health, Veterinary, and Agricultural Significance. Comparative acute and combinative toxicity of aflatoxin B1 and fumonisin B1 in animals and human cells. Mutagenic effects of selected trichothecene mycotoxins and their combinations with aflatoxin B1. Human aflatoxicosis in developing countries: a review of toxicology, exposure, potential health consequences, and interventions. Furthermore, only a small proportion have been chemically characterized and reported to cause health effects in humans and animals. Alternaria toxins are divided into different classes based on their chemical structures. The third class is the tetramic acids, which include tenuazonic acid (TeA) and iso-tenuazonic acid (iso-TeA). The level of radioactivity in tissues was very low, and the study was not designed to evaluate distribution at early time points (apparently no blood sampling or interim sacrifices were performed). Theoretically, it is possible that the high fecal excretion reflects biliary excretion. The four major catechol metabolites and their O-methyl ethers reported by the same authors as being formed by microsomal incubation systems and by liver slices were present in the bile. Diarrhea, muscle tremor and convulsions were reported symptoms from these studies. Necropsy findings, including "examination of the reproductive tracts for estrogenic effects," were negative, but additional details were not provided. The groups with TeA in the diet at 145 ppb and higher had signs of toxicity, including decreased food consumption, weight loss, and death. In addition, one animal had bloody diarrhea and become moribund after 2 days at the high dose. The other monkey continued vomiting after treatment, but "tolerated the treatment" at the high dose for 15 days. The actual high dose is unknown, since the vomiting may have eliminated much of the TeA. Diarrhea, vomiting and hemorrhages in the lung and gastrointestinal tract were also reported, along with microscopic evidence of hemorrhage in other organs and degenerative changes in the liver. As for the monkey study, the actual dose is unknown, since the vomiting may have eliminated much of the TeA. Fetal survival, "runts" (not further defined), and malformations (visceral and skeletal) were reported. The authors reported no evidence of fetotoxicity and no statistically significant increase in malformed fetuses at the single dose tested. However, study reporting is limited, and the group sizes were small (4-14 dams, depending on dose and control). In contrast, there was evidence of fetotoxicity at sufficiently high doses following parenteral administration (Pero et al. Other studies investigated specific Alternaria mycotoxins, as opposed to mold extracts. The concentration in drinking water was adjusted based on the water consumption to maintain constant dosing. Precancerous changes ranging from mild dysplasia to severe dysplasia were reported in the esophageal mucosa. Sphingolipids are structural components of cell membranes and play a role in proliferation and cell death. The mechanism of cytotoxicity for TeA is reported to be the inhibition of protein synthesis by inhibiting protein release from the ribosomes. It bound to cell-free recombinant human estrogen receptor and functioned in some assays as a weak estrogen receptor antagonist, although results differed in different test systems. Limited data also suggest that TeA affects the gastrointestinal tract and causes hemorrhaging in the lung, gastrointestinal tract, and other organs. Oxidative metabolism of the mycotoxins alternariol and alternariol-9-methyl ether in precision-cut rat liver slices in vitro. Scientific Opinion on the risks for animal and public health related to the presence of Alternaria toxins in feed and food. Analysis of toxic effects of Alternaria toxins on esophagus of mice by light and electron. A recent study conducted a careful screen of the metabolites formed from 25 strains of C. Minor metabolites included 94 chaetomugilin I, chaetoviridin E, azaphilones, and other chaetoglobosins. Other strains have been reported to produce chetomin, chaetocin, and cochliodinol, but McMullin et al. Chaetochromin is a polyphenolic compound that is reported to be isolated from several Chaetomium species (Ito and Ohtsubo, 1987). Other metabolites that have been identified include epipolythiodioxopiperazines, xanthones, anthraquinones, chromones, depsidones, terpenoids, and steroids (Zhang et al. Physical and Chemical Characteristics of Chaetomium Toxins Characteristic Chaetoglobosin A Molecular formula Molecular weight Physical State Chaetoglobosin F Molecular formula Molecular weight Physical State Chaetoglobosin C Molecular formula Molecular weight Physical State Chaetomugilin D Molecular formula Molecular weight Physical State Chaetoviridin A Molecular formula Molecular weight Physical State Reference McMullin et al. These studies found high toxicity and rapid death following parenteral injection, but much lower toxicity via oral exposure. Toxic effects noted included hypokinesis, coldness and edematous swelling at the site of injection. Toxic effects noted included pulmonary congestion, scattered necrosis of the spleen and depletion of thymocytes, as well as spermatocyte degeneration. After 3 days of recovery, only effects on the thymus and testes were noted, and no histological abnormalities were seen after 7 days of recovery (Ohtsubo et al. There was no maternal toxicity, based on changes in body weight, organ weight, or histological findings, although there was an increase in mitotic figures in the liver at both doses. Fetal data were reported only as average results, not in the more appropriate form of per litter analyses. Statistically significant decreases in living fetuses and increased resorptions were seen at the high dose. Malformations, including exencephaly were observed in 10 of the 97 fetuses on the diet containing 30 ppm of the fungal toxin. There was no clear positive response, although there was a slight increase in mutation frequency. Isolates from 14 different Chaetomium strains inhibited ciliary beating in a chick tracheal organ culture (Pieckova, 2003), but the significance of this observation is unclear in the absence of reported doses. The results suggest chaetoglobosin F may act as an immunosuppressor at sufficiently high doses (Hua et al. In addition, insufficient data are available to make generalizations by class of toxin. However, a single incompletely reported study suggests that chaetochromin may cause developmental effects. There are also inconsistent reports of liver and immunotoxicity with chaetochromin, with differences observed across mouse strains. The limited data available on chaetoglobosin A suggests that its oral toxicity may be low. Teratogenicity of oral Chaetochromin, a polyphenolic mycotoxin produced by Chaetomium spp. Chaetoglobosins and azaphilones produced by Canadian strains of Chaetomium globosum isolated from the indoor environment. Acute toxic effects of Chaetoglobosin A, a new cytochalasan compound produced by Chaetomium globosum, on mice and rats. Cyclosporine is used clinically as an immunosuppressant, and so data are available from both extensive animal toxicity testing and controlled human exposure. In human blood, cyclosporine is extensively distributed in erythrocytes (Tedesco and Haragsim, 2012). Bioavailability after an oral dose reflects inter-individual variability in intestinal absorption, which is affected by factors, such as food ingestion, disease, stomach problems, and diarrhea. The peak blood concentration of cyclosporine following oral pharmacologic dosing occurs between 1 and 8 hours. The immunosuppressive effects of cyclosporine are attributed to the parent compound. Metabolism in humans is primarily via the hepatic cytochrome P450 system, followed by biliary excretion with a half- life of 6. Hydroxylation via the P450 system is followed by secondary metabolism, either to further oxidation products or via demethylation of the primary metabolites. Cyclosporine given orally to dogs and rats is absorbed and widely distributed throughout the animal. In rats, slow elimination occurred and even after 5 days significant amounts were observed. There was no evidence of accumulation in dogs following repeated dosing for a year (Ryffel et al. Cyclosporine is a potent immunosuppressant, and is used to prevent organ and tissue rejection following transplantation. Dosing and length of time for treatment depend on the type of treatment, with transplant patients receiving higher doses than other therapeutic applications. For example in patients being treated for rheumatoid arthritis, the initial dosing is 1. For patients with kidney dysfunction or disease, the dose is much lower, starting with 2. While oral and iv administration are most common, cyclosporine formulations are also available for parenteral, rectal, ophthalmic and pulmonary aerosol administration (Ragab et al. These doses for typical treatments (at which varying levels of immunosuppression occur) provide perspective on the doses at which adverse side effects are reported. Nephrotoxicity is one of the most frequent toxic side effects observed following therapeutic dosing with cyclosporine. Cyclosporine as an immunosuppressive drug has a narrow therapeutic index (Da Silva et al. Acute nephrotoxicity caused by cyclosporine is characterized by renal vasoconstriction and renal dysfunction, and is reversible with discontinuation or reduction of the cyclosporine dose. Chronic nephrotoxicity, on the other hand, is irreversible and involves serious structure damage such as arteriolopathy and tubulointerstitial fibrosis (Lee, 2010). Several of these effects are likely associated with impaired kidney function, and these effects in general are consistent with the animal observations described below. Although it is a primary reference, it provides much less detail than is typically standard for such studies. Adverse effects noted include hyperventilation, drowsiness, muscular spasms, weight loss and diarrhea. At the two highest doses, adverse effects in both species included degenerative changes in the kidney and liver, changes in serum chemistry consistent with the liver and kidney effects, decreases in red blood cell markers but not white blood cells, marked neurological effects (sedation, ataxia), and atrophy of lymphoid tissue (Ryffel et al.
Because the half-life of normeperidine is 16 hours hair loss cure 51 discount finpecia 1mg with visa, it may take 2 or 3 days for the signs of central nervous system hyperirritability to clear completely hair loss 55 cheap 1mg finpecia amex. Meperidine is contraindicated in patients with chronic renal disease hair loss cure man finpecia 1mg cheap, but these complications noted in cancer pain occurred in patients with normal renal function hair loss shampoo for women order 1mg finpecia overnight delivery. Opioid hyperexcitability and hyperalgesia have been reported with the use of increasing opioid doses by the parenteral acute and epidural routes hair loss 3 months after stress buy discount finpecia 1 mg on-line. It has most often been observed in patients on high doses of morphine and hydromorphone and is characterized by uncontrolled pain hair loss in men at 50 cheap 1 mg finpecia free shipping, hypervigilance, total body hyperalgesia, and allodynia. It is best managed by rapid dose reduction and substitution with an alternative opioid such as methadone. It is suggested that high doses of morphine or its metabolites may act via a spinal antiglycinergic effect, reducing postsynaptic inhibition causing allodynia and myoclonus. For reasons not yet understood, the rate of development of tolerance varies greatly among cancer patients. Studies in an outpatient clinic population, a hospitalized population, and a home care population revealed three patterns of drug use: those who rapidly increase their opioid requirements, those who stabilize at one dose for several weeks or months, and those who decrease or eliminate opioids. With the development of tolerance, increases in the frequency of the dose of the opioid are required to provide continued pain relief. Because the analgesic effect is a logarithmic function of the dose of opioid, a doubling of the dose may be needed to restore full analgesia. There appears to be no limit to the development of tolerance, and with appropriate dose adjustments patients can continue to obtain pain relief. Similarly, the use of bolus or continuous epidural local anesthesia in patients with perineal pain can dramatically reduce the need for systemic opioids and reverse tolerance. The appearance of abstinence symptoms from the time of drug withdrawal is related to the elimination half-life for the particular drug. For example, with morphine, withdrawal symptoms occur within 6 to 12 hours after drug cessation. Intentional overdose in cancer patients occurs rarely, and concern for this is overemphasized. Overdose in patients previously stabilized on a opioid regimen for cancer pain rarely is caused by drug intake alone. More commonly, it is the medical deterioration of the patient with a superimposed metabolic encephalopathy. Eagel studied the use and misuse of naloxone and identified that sedation was the most common reason for naloxone use. Patients who have taken an unintentional drug overdose should be scrutinized carefully to rule out other causes of excessive sedation, confusion, or respiratory depression. In such cases a reversal of these effects with naloxone is more therapeutic than diagnostic. Psychological dependence or addiction is characterized by a concomitant behavioral pattern of drug abuse evidenced by craving a drug for other than pain relief and overwhelming involvement in the use and procurement of the drug. This is a state distinct from tolerance and physical dependence, which are responses to the pharmacologic effects of long-term opioid administration. Patients may share this fear, consistently taking less analgesic drug than is effective to control their pain. Increasing evidence suggests that cancer patients with pain can take opioid analgesics for prolonged periods but can discontinue such drugs when adequate pain relief is achieved from other approaches. In almost all instances, dramatic escalation of drug intake is associated with progression of disease and subsequent death. Few patients with cancer and pain become psychologically dependent on the drugs and participate in drug-seeking and illicit drug use. Careful evaluation of patients who might be at risk for this complication is necessary, but such concern should not be punitive to the patient with severe cancer pain. Out-of-control aberrant drug taking among oncology patients with or without a prior history of substance abuse represents a serious and complex clinical occurrence. Such patients need a multidisciplinary approach usually focused on a harm-reduction concept that attempts to enhance social support for the patient to maximize treatment compliance. It is often most useful to see the patient on a regular basis, often every several days, and to limit prescribing of opioids to that basis until the patient has demonstrated his or her willingness to be compliant and to follow an appropriate drug regimen. Such approaches can be helpful on an outpatient basis, but on an inpatient basis when patients demonstrate manipulative behaviors in the inappropriate use of medication, direct discussion with the patient about the drug use in an open manner is a first step. As well, the use of daily urine specimens is another method to evaluate compliance. Because of the lack of well-defined guidelines for their use, sequential drug trials are necessary to identify the most useful drug and dose titration to find a safe effective dose. Adjuvants to Enhance Analgesia Adjuvants to enhance analgesia have been previously discussed in the section on combinations of drugs (see Use a Combination of Drugs, earlier in this chapter). Adjuvant Analgesics for Neuropathic Pain the common neuropathic pain syndromes in patients with cancer include injury to peripheral nerves and plexus by tumor invasion, chemotherapy, surgery, or viral agents. Depending on the intensity of pain, nonopioid and opioid analgesics are the first-line agents. However, as previously discussed, there is evidence to suggest that such neuropathic pains are less responsive to nonopioid and opioid approaches. Some of the commonly used adjuvant drugs for managing this population of patients are described in the following sections. Antidepressants the tricyclic antidepressants may be the most useful group of psychotropic drugs used in pain management. Data from controlled trials indicate that both the tertiary amine tricyclic antidepressants (amitriptyline, doxepin, imipramine and clomipramine), and the secondary amine compounds (desipramine and nortriptyline) have analgesic effects. More recently, one of the serotonin selective reuptake inhibitors, paroxetine, has also been shown to have analgesic properties in patients with neuropathic pain. The doses used for analgesia are far below those needed to produce an antidepressant effect. The analgesic properties of these drugs appear to occur independent of their mood-altering effects. Patients should be started on low doses of 10 to 25 mg and titrated up to achieve adequate analgesia in a 2- to 4-week trial. Blood levels should be measured to determine both patient compliance and drug absorption, because of wide individual variation. Patients who are unable to tolerate amitriptyline, or who are predisposed to its sedative, anticholinergic or hypotensive effects, should be considered for a trial with a secondary amine tricyclic antidepressant, or a serotonin selective reuptake inhibitor such as paroxetine. In the management of cancer patients with pain, the antidepressant drugs are the first-line therapeutic approach for neuropathic pain, and every attempt should be made to provide the patient with a several-week trial before discontinuing these drugs. Anticonvulsants the role of anticonvulsants in the management of patients with neuropathic pain is based, in part, on the fact that the mode of action is to stabilize membranes and alter sodium and calcium influx. The drugs most commonly used include gabapentin, carbamazepine, phenytoin, valproate, and clonazepam. Gabapentin is considered the first-line anticonvulsant to manage neuropathic pain. Controlled trials in diabetic neuropathy, postherpetic neuralgia, and acquired immunodeficiency syndrome neuropathy demonstrate the effectiveness of this agent in reducing pain. Clinical studies with carbamazepine demonstrate efficacy, but the utility of this drug in the cancer population is limited by its potential to produce bone marrow suppression, particularly leukopenia. The dosing guidelines used for the treatment of seizures are suggested in managing neuropathic pain. There is anecdotal experience to suggest that using intravenous loading doses of phenytoin for patients in an acute crisis with severe lancinating pain may be of clinical value. Both valproate and clonazepam have been reported anecdotally to be useful in neuropathic pain, but these are considered third-line agents in this patient population. Currently, there are no data to relate the plasma level and pain relief with any of these drugs. As previously stated, sequential trials are necessary to identify the most useful agent. Mexiletine is the oral local anesthetic for which there are pilot data to support its analgesic efficacy. Electrocardiograms should be monitored at higher doses, and blood levels of mexiletine may be useful to prevent toxicity. Currently, there are no good data available to predict what patient might respond to the use of oral local or intravenous anesthetics, as have been done in the use of brief local anesthetic infusions to determine control of cardiac arrhythmias. Epidural local anesthetics (bupivacaine, lidocaine) have been most widely used to manage neuropathic pain either alone or in combination with opioid. Alternatively, the use of brief intravenous infusions of lidocaine may be helpful in patients who have an opioid-refractory continuous dysesthesia that has not responded to an antidepressant or anticonvulsant. The use of cutaneous anesthesia has been suggested to be most helpful in patients who have significant allodynia and marked hyperesthesia. The use of the topical application of a local anesthetic, such as a eutectic mixture of local anesthetics, has been demonstrated to be efficacious in patients with postherpetic neuralgia. The risk of adverse effects associated with corticosteroid therapy varies with the duration. Long-term use may be associated with gastrointestinal toxicity and acute psychosis. As stated, with epidural cord compression, initial doses of 100 mg with maintenance doses of 16 mg have been associated with effective analgesia. Of the benzodiazepines, clonazepam is commonly used in patients with lancinating or paroxysmal pain. They serve as second- to third-line therapy in patients who have not responded to antidepressant or anticonvulsant drug therapy. Of the neuroleptics, pimozide has been reported to be analgesic in patients with trigeminal neuralgia. Coadministration of these drugs with opioids can often be effective in patients with neuropathic pain. Of the a 2-adrenergic agonist drugs, clonidine has been demonstrated to be analgesic in controlled trials. Following intrathecal administration, clonidine was reported to improve pain in patients with intolerable neuropathic pain. Case reports have suggested that dextromethorphan has been beneficial in selected patients, although a controlled trial of low-dose dextromethorphan had negative results. Studies of dextromethorphan combined with opioids demonstrated added analgesia, suggesting an opioid-sparing effect of the drug. The use of ketamine infusions have been previously well established to produce analgesia, and they have been reintroduced into clinical use as brief infusions for the management of patients with refractory neuropathic pain. Further studies are necessary to demonstrate the safety and efficacy of these treatment approaches in long-term management for chronic neuropathic pain. Oral ketamine in case reports has demonstrated efficacy in cancer patients with pain uncontrolled by other approaches. Calcitonin has been reported to provide analgesia in patients with sympathetically maintained pain and in the management of acute phantom pain. Its use chronically has not been assessed, and further studies are necessary to define its place in the treatment of patients with neuropathic pain. Adjuvants for Bone Pain Metastatic disease to bone is the most common cause of pain in patients with cancer. Analgesic drug therapy is commonly used to manage the pain during the initial treatment with either chemotherapy or radiation therapy. Numerous investigators have identified a management approach for bone pain, which includes the use of specific surgical palliative approaches, radiotherapeutic approaches, hormonal therapies, and bone resorption inhibitors. Multifocal metastatic bone disease that is refractory to routine treatments may benefit from the use of a series of agents, including the bisphosphonate compounds, gallium nitrate, calcitonin, and strontium 89. The current bisphosphonates most widely studied for the treatment of bone pain include pamidronate and clonidronate. Analgesia, if it occurs, usually appears within days, but may accrue for many weeks with repeated infusions. Current recommendations include a regimen of intravenous pamidronate, 60 mg every 2 weeks for at least two or three treatments. A study of pamidronate, 120 mg intravenously, versus placebo in patients with painful bone metastases revealed a correlation between analgesic response and collagen cross-links suggesting such peptide cross-links may be used to select those patients more likely to achieve improvement in pain with bisphosphonate therapy. The major indication of these drugs is to prevent skeletal morbidity, with data in breast cancer patients and patients with multiple myeloma showing efficacy in reduction of fractures and reduction in bone pain. Clonidronate may be administered orally and has been demonstrated to be efficacious in patients with breast cancer and multiple myeloma. Calcitonin has also been reported anecdotally to be useful in patients with malignant bone pain, but the appropriate dose and dosing frequency have not been well defined. The onset of effect is slow and may require several weeks, with peak effects at 2 to 3 months. Bone marrow suppression is the major adverse effect, with irreversible thrombocytopenia. The selection of any one of these treatments in metastatic bone pain needs to be individualized, with evidence that both the bisphosphonates and strontium 89 have clearly demonstrated efficacy in certain patients. Adjuvants to Treat Side Effects Nausea and vomiting, confusion, sedation, and constipation are common opioid-induced side effects. The use of drugs to manage these have been previously discussed (discussed earlier, in Anticipate and Treat Side Effects). The use of caffeine, methylphenidate, and dextroamphetamine have all been demonstrated in clinical trials to reduce opioid-induced sedation. Haloperidol is the treatment of choice to manage hallucinations and agitated delirium in patients receiving opioid analgesics. The use of bowel regimens to manage depressed gastrointestinal motility have also been discussed. A series of psychological variables contribute to the cancer pain experience and suffering, such as perception of control, the meaning of pain, fear of death, depressed mood, and hopelessness. The level of psychological distress experienced by each patient varies depending on personality, coping ability, social support, and medical factors. Pain has a profound effect on levels of emotional distress, and psychological factors such as depression and anxiety intensify the pain experience.

High sensitivity is required not to overlook early lung cancer but simultaneously acceptable specificity have to be ensured in order to reduce futile invasive diagnostics and treatment procedures related to false positive diagnoses (1 hair loss in men michael order 1 mg finpecia with mastercard,2 himalaya anti hair loss purchase 1 mg finpecia amex,3) hair loss reviews finpecia 1 mg with amex. The experience of the multidisciplinary team and adoption of the specific radiological protocol that is strictly followed is a mainstay of successful lung cancer screening program yves rocher anti hair loss buy finpecia 1 mg otc. Thoracic radiologist is responsible for the reduction of false positive rate to a safe minimum. This goal can only be achieved by strict adherence to the guidelines and protocol for the assessment of nodules. LungRads or volumetry with assessment of volume doubling time should be applied to minimize false positive rate. The multidisciplinary discussion on tumor board meeting of the suspected cases is another element leading to the reduction of unnecessary invasive diagnostics and surgery in non-malignat leasions that produces harm, entails risk of complictions and increases costs (3). In Gdask where two screening programs were conducted during last 10 years most harmfull aspects were reduced almost doublefold (tab. This method has great potential in the future treatment of small nodules detected in lung cancer screening programs. The minimally invasive techniques in the future treatment of screening detected cancers are the only treatment options that could be accepted in this context.

There continues to be a dearth of research studies by allied health professionals, particularly in the area of oncology and more specifically lung cancer. For our professions to continue to grow in this speciality area and demonstrate our benefit, we need to engage and support clinicians to bring research into their daily clinical practice, to ensure a robust evidence base in oncology, and more specifically lung cancer, is developed. Keywords: Nursing, Allied health, Clinical research the nursing and allied health professions include a diverse range of disciplines, such as many different specialist nurses, physiotherapy, occupational therapy, speech and language pathology, dietetics, social work, and others. The foundation of modern health service interventions is that of evidence-based practice, to ensure that patients are receiving interventions that have been proven, through robust research, to provide benefit for the patient. Nursing interventions have a longer history of research underpinning them than allied health. In the allied health professions, there remains a dearth of robust research providing a clear evidence base for interventions routinely used. This presentation will focus on the challenges faced by both nurses and allied health professionals, particularly clinicians, in undertaking research and, once a research study is completed, how to get the research published. This is even more challenging in the general speciality of oncology and within the sub-specialty of lung cancer. The lack of research among nursing and the allied health professions is not a new phenomenon. The aim of this research was to ensure the scientific knowledge base of the interventions being utilised were valid and reliable. The outcome of the research demonstrated a significant limitation in the replication of research, with many interventions being utilised by these professions not having a strong evidence base, or any evidence base at all. Twenty-five years later the scientific base for these professions, as well as dieticians and new and emerging allied health professions, has improved. In the field of occupational therapy most national professional bodies now have a focus on supporting research through funding and the dissemination of research findings. How does a novice clinical researcher go about funding, designing, implementing and publishing a research study? One of the keys for novice researchers is to find an academic or clinical research mentor, who is able to support you in navigating the muddy waters of clinical research. Clinical research is key to ensuring research projects are designed to meet the needs of our rapidly changing clinical environment, emerging clinical areas and interventions. These include a lack of research competency and training, the pressure of large clinical caseloads, a lack of support from within nursing and allied health departments, as well as at a hospital level, where the priority is primarily for patient intervention, not research. In this presentation I will outline how I navigated my initial clinical research in lung cancer and progressed over time to become an applied public health researcher in cancer control. Throughout this research progression I have had the support of mentors and supervisors while completing higher degrees, as well as clinical champions in my workplaces. I will outline the steps required to develop a research project, including protocol development, practical tips for managing Human Research Ethics and Governance Committee applications, data collection and management. Publish or perish remains a key concept for nursing and allied health professionals. While in some health conditions, such as paediatrics, spinal cord injury, and acquired brain injury to name a few, there is a strong body of evidence for allied health interventions, in oncology, specifically lung cancer, a dearth of evidence from the allied health professions continues. There has been an improvement in research in some specific areas of lung cancer management which involves allied health professionals, such as in exercise, rehabilitation, and psychosocial support. However, significant gaps in the evidence base for allied health interventions for people living with lung cancer remain. There has been a growth in nursing research, particularly in lung cancer, but how robust is this research output? Internationally, both nursing and allied health professionals may be completing research or quality improvement activities that are building on their evidence base. One of the most important and indeed respected means of disseminating information is publish your results in a peer reviewed journal. While this may sound very straightforward, those who have tried to publish their data will be familiar with the frustration with peer reviewers, of rejection without peer review, rejection following extensive peer review or the need to submit a completely revised manuscript. Here I will discuss some of the key principles of getting your paper published, based on my experience as an author, reviewer and associate editor. I will go cover a range of areas from writing a good cover letter, what to include in the paper, to how to respond to reviewers. There are no guarantees to getting your paper published where you want the first time round, but these pointers will hopefully enable you to pick the right type of publication, the right journal and the best way to frame your paper. Consequently, an increasing number of post-treatment resistance mechanisms have also been identified. Adequate molecular testing is therefore critical for the identification of such alterations for appropriate treatment planning. The necessity for this was due not only to the rapid advances in identification of targetable mutations but also to improved technologies with which genetic variants could be identified. The guidelines were recommended for advanced stage adenocarcinomas or tumors with an adenocarcinoma component. Much latitude was left to individual practices in regard to testing early stage cancers and tumors with non-adenocarcinoma histology. In the time since the publications of these guidelines in 2018, the number of therapeutic targets has continued to increase. Additionally, there has been increased focus on neoadjuvant use of targeted therapies. While misconceptions remain, cytology specimens are perfectly adequate for molecular testing provided sufficient material is present, an issue which can be a factor in any small biopsy specimen. In spite of these advances, it is recognized that significant knowledge gaps and limitations exists in regard to testing. As such, a significant number of lung cancer specimens do not undergo appropriate molecular testing. Further, access to testing, debates regarding cost-effectiveness, issues with reimbursement and optimal approaches in resource-limited areas remain a challenge. Each of these steps has a major influence on the assay output, including breadth of coverage (how much of the genome to sequence? The drawback to the approach, however, is high cost, limited analytic sensitivity, and suboptimal capture and sequencing of highly repetitive regions, leading to poorly-covered or uncovered areas of the genome. In addition, introns tend to contain a much higher proportion of repetitive elements, thus the tools used for rearrangement detection must be able to discern the presence of these variants despite low sequencing coverage and nonspecific sequence mismatches. In practice, these issues lead to reduced clinical sensitivity for detection of large deletions and rearrangement events. Improvements in assay design, chemistry, bioinformatics and variant interpretation will continue to increase its reliability and use across tumor and specimen types.

Somatostatin receptor expression in small cell lung cancer as a prognostic marker and a target for peptide receptor radionuclide therapy. It is a rare but very severe complication which requires prompt treatment because of the involved disruption of the natural tissue barriers against infection. Significant dyspnea can occur because of increased dead space ventilation if there is a massive air leak. The diagnosis can be made by bronchoscopy and if the bronchoscopist cannot see a fistula, deposition of methylene blue at the site of the stump can help. In case of persistent air leak and no identifiable airway fistula, an alveolar-pleural fistula (more common) should be considered. Reconstruction of the stump or anastomosis can be followed by adding a muscle flap to improve perfusion. In case of complex empyema, open window thoracostomy can be necessary, especially if more conservative measures have been unsuccessful. Symptoms include cough, especially during intake of food or liquids, infection (bronchitis, pneumonia), recurrent aspiration and weight loss. In patients with lung cancer, the most important causes are malignant invasion of the membranous part of the trachea or bronchi and highdose radiotherapy with involvement of airways in close proximity to the esophagus (trachea and proximal left main bronchus). The diagnosis can be made with contrast-enhanced esophagography, demonstrating displacement of the contrast into the lung. Bronchoscopy can be used to localize the fistula, to determine its extent, to assess the vitality of the surrounding airway wall and to evacuate aspirated liquids and mucus from the central airways. To minimize further aspiration, oral intake should be eliminated and adequate measures should be taken to minimize reflux and ensure adequate feeding. Small fistulas (up to 5 mm) can be treated endoscopically with cyanoacrylate glue or clips. Larger fistulas can be treated with an esophageal stent, airway stent or a combination: double stenting. Often multiple endoscopic interventions are required to achieve and maintain adequate palliation. During this presentation the management of airway fistulas will be discussed, with emphasis on the bronchoscopic techniques such as (double) stenting and the application of cyanoacrylate glue. Selection of patients, alternative solutions and specific endoscopic techniques will be important topics.

Commonly Used Radiopharmaceuticals Technetium-99m Imaging Considerations Primarily used to evaluate global and regional ventricular function and to determine ejection fraction(s) May be used in the evaluation of intracardiac shunting or diastolic function First-pass studies display initial transit of the radiotracer bolus passing through the cardiopulmonary and central systemic circulations. First pass studies should be acquired on a high count-rate camera in order that images have sufficient temporal resolution. While it is possible to acquire images during exercise in patients undergoing bicycle exercise testing, image quality during treadmill exercise is suboptimal. Thus, the laboratory must be set up in a manner that allows imaging to be completed within 45 to 60 seconds after peak exercise.
