Abstract
BACKGROUND Pancreatic fluid collections (PFCs) may recur after resolution with endoscopic transmural drainage (ETD) and standard stent removal (SSR). Herein, we compared the efficacy and safety of leaving long-term indwelling plastic stents (LTIS) vs. standard stent removal after PFC resolution with ETD. METHODS We performed a systematic review of MEDLINE, EMBASE, CINAHL, Scopus, and Cochrane databases from inception to September 2022. Full-text articles comparing long-term (> 6 months) outcomes of LTIS and SSR were eligible, as well as single-arm studies with ≥ 10 patients with LTIS. Two independent reviewers selected studies, extracted data, and assessed the risk of bias using the Newcastle-Ottawa Scale. Measured outcomes included the following: (A) PFC recurrence; (B) interventions for PFC recurrence; (C) technical success; and (D) adverse events (AEs). Meta-analysis was carried out using random-effects models. RESULTS We included 16 studies, encompassing 1285 patients. Compared to SSR after PFC resolution with ETD, LTIS was associated with significantly lower risk of PFC recurrence (3% vs. 23%; OR 0.22 [95%CI 0.09-0.52]; I2 = 45%) and need for interventions (2% vs. 14%; OR 0.35 [95%CI 0.16-0.78]; I2 = 0%). The superiority of LTIS on reducing PFC recurrence was found with walled-off necrosis, with or without disconnected pancreatic duct, and with placement of ≥ 2 LTIS. When using LTIS, the pooled proportion of AEs was 8% (95%CI 4-11%) and technical success was 93% (95%CI 86-99%). CONCLUSIONS Our results show that LTIS after PFC resolution with ETD is feasible, safe, and superior to SSR in reducing the risk of PFC recurrence and need for interventions.

Abstract
BACKGROUND & AIMS Understanding the burden of pancreatic cystic lesions (PCLs) in the general population is important for clinicians and policymakers. In this systematic review, we sought to estimate the global prevalence of PCLs using magnetic resonance imaging (MRI) and to investigate factors that contribute to its variation. METHODS We searched MEDLINE, EMBASE, and Cochrane Central, from database inception through February 2023. We included full-text articles that reported the prevalence of PCLs using MRI in the general population. A proportional meta-analysis was performed, and the prevalence of PCLs was pooled using a random-effects model. RESULTS Fifteen studies with 65,607 subjects were identified. The pooled prevalence of PCLs was 16% (95% confidence interval [CI], 13%-18%; I2 = 99%), most of which were under 10 mm. Age-specific prevalence of PCLs increased from 9% (95% CI, 7%-12%) at 50 to 59 years, to 18% (95% CI, 14%-22%) at 60 to 69 years, 26% (95% CI, 20%-33%) at 70 to 79 years, and 38% at 80 years and above (95% CI, 25%-52%). There was no difference in prevalence between sexes. Subgroup analysis showed higher PCL prevalence when imaging findings were confirmed by independent radiologist(s) (25%; 95% CI, 16%-33%) than when chart review alone was used (5%; 95% CI, 4%-7%; P < .01). There was no independent association of PCL prevalence with geographic location (Europe, North America, or Asia), MRI indication (screening vs evaluation of non-pancreatic pathology), enrollment period, sample size, magnet strength (1.5 vs 3 tesla), and MRI sequence (magnetic resonance cholangiopancreatography vs no magnetic resonance cholangiopancreatography). CONCLUSION In this systematic review, the global prevalence of PCLs using a highly sensitive noninvasive imaging modality ranged between 13% and 18%.

Abstract
BACKGROUND Dual targeted therapy (DTT) has emerged as an attractive therapeutic option for select patients with active inflammatory bowel disease (IBD) who are unable to achieve remission with biologic or small molecule monotherapy. We conducted a systematic review of specific DTT combinations in patients with IBD. METHODS We conducted a systematic search of MEDLINE, EMBASE, Scopus, CINAHL Complete, Web of Science Core Collection, and Cochrane Library to identify articles related to the use of DTT for the treatment of Crohn Disease (CD) or ulcerative colitis (UC) published before February 2021. RESULTS Twenty-nine studies were identified comprising 288 patients started on DTT for partially or non-responsive IBD. We identified 14 studies with 113 patients receiving anti-tumor necrosis factor (TNF) and anti-integrin therapies (i.e., vedolizumab and natalizumab), 12 studies with 55 patients receiving vedolizumab and ustekinumab, nine studies with 68 patients receiving vedolizumab and tofacitinib, five studies with 24 patients receiving anti-TNF therapy and tofacitinib, six studies with 18 patients receiving anti-TNF therapy and ustekinumab, and three studies with 13 patients receiving ustekinumab and tofacitinib. CONCLUSION DTT is a promising approach to improve IBD treatment for patients with incomplete responses to targeted monotherapy. Larger prospective clinical studies are needed to confirm these findings as is additional predictive modeling to identify the patient subgroups most likely to require and benefit from this approach.

Abstract
BACKGROUND/AIMS Thromboelastography (TEG) and Rotational Thromboelastometry (ROTEM) analyze hemostatic function in patients with coagulopathy. We sought to quantify the impact of TEG and ROTEM-guided transfusion algorithms on blood product utilization in patients with cirrhosis undergoing non-surgical procedures. METHODS We performed a systematic review and meta-analysis on the utility of viscoelastic testing prior to non-surgical procedures to determine their impact on pre-procedural blood product use and post-procedural bleeding events. Studies comparing TEG or ROTEM-guided transfusions with standard-of-care (SOC) prior to non-surgical procedures in adult patients with cirrhosis were included. Primary outcomes were fresh frozen plasma (FFP) and platelet transfusion and secondary outcomes of post-procedure bleeding, transfusion-related complications, and mortality; and were reported as standardized mean differences (SMD) and risk ratios (RR). RESULTS Six studies (five randomized controlled trials and one cohort study) involving 367 patients met inclusion criteria. Compared with SOC, TEG/ROTEM-guided transfusions led to an overall decreased number of patients who received FFP transfusions (SMD = -0.93, 95% CI [-1.54, -0.33], p < 0.001) and platelets transfusions (SMD = -1.50, CI [-1.85, -1.15], p < 0.001). Total amount of FFP (SMD-0.86, p < 0.001) and platelet (SMD = -0.99, p < 0.001) transfused in the TEG/ROTEM group were also lower. Decreased pre-procedure transfusion in the TEG/ROTEM group did not result in increased post-procedure bleeding (RR = 0.61, p = 0.09) or in mortality (RR = 0.91, p = 0.93). CONCLUSION In patients with cirrhosis, TEG or ROTEM significantly reduces blood product utilization prior to non-surgical procedures, with no increase in post-procedure bleeding or mortality. TEG and ROTEM utilization can promote high-value care and improve transfusion stewardship in this population.

Abstract
BACKGROUND AND OBJECTIVES Alzheimer disease (AD) and other forms of dementia represent a rising global public health crisis. Because effective treatments to prevent, cure, or slow progression of dementia are unavailable, identification of treatable risk factors that increase dementia risk such as obstructive sleep apnea (OSA) could offer promising means to modify dementia occurrence or severity. Here, we systematically reviewed the impact of positive airway pressure (PAP) therapy on the incidence of cognitive disorders and cognitive decline among middle-aged and older adults with OSA. METHODS We performed a systematic search of MEDLINE, EMBASE, Scopus, and CINAHL before May 2021 to identify articles that focused on associations between PAP therapy use and cognitive disorders. We included studies that examined the effects of PAP treatment on (1) the incidence of cognitive disorders among individuals ≥40 years of age diagnosed with OSA and (2) the progression of cognitive decline among people with preexisting cognitive disorders and OSA. RESULTS We identified 11 studies (3 clinical trials and 8 observational studies). In these studies, 96% participants had OSA (n = 60,840) and 9% had baseline cognitive impairment (mild cognitive impairment [MCI] or AD) (n=5,826). Of all study participants, 43,970 obtained PAP therapy, and 16,400 were untreated or in a placebo group. Nine out of 11 studies reported a protective effect of PAP therapy on MCI and AD incidence, e.g., delayed age at MCI onset, reduced MCI or AD incidence, slower cognitive decline, or progression to AD. DISCUSSION These findings suggest a role for OSA as a modifiable risk factor for cognitive decline. Identification of modifiable risk factors is imperative for alleviating the impact of cognitive disorders on aging adults and their family members. Future research should build on this review and focus on PAP interventions as a potential means to alleviate the incidence of cognitive disorders and cognitive decline, particularly among ethnoracial groups who have been underrepresented and underinvestigated in the extant literature.

Abstract
BACKGROUND AND AIMS Intestinal strictures are a common complication of Crohn's disease (CD). Biomarkers of intestinal strictures would assist in their prediction, diagnosis, and monitoring. Herein we provide a comprehensive systematic review of studies assessing biomarkers that may predict or diagnose CD-associated strictures. METHODS We performed a systematic review of PubMed, EMBASE, ISI Web of Science, Cochrane Library, and Scopus to identify citations pertaining to biomarkers of intestinal fibrosis through July 6, 2020, that used a reference standard of full-thickness histopathology or cross-sectional imaging or endoscopy. Studies were categorized based on the type of biomarker they evaluated (serum, genetic, histopathologic, or fecal). RESULTS Thirty-five distinct biomarkers from 3 major groups were identified: serum (20 markers), genetic (9 markers), and histopathology (6 markers). Promising markers include cartilage oligomeric matrix protein, hepatocyte growth factor activator, and lower levels of microRNA-19-3p (area under the curves were 0.805, 0.738, and 0.67, respectively), and multiple anti-flagellin antibodies (A4-Fla2 [odds ratio, 3.41], anti Fla-X [odds ratio, 2.95], and anti-CBir1 [multiple]). Substantial heterogeneity was observed and none of the markers had undergone formal validation. Specific limitations to acceptance of these markers included failure to use a standardized definition of stricturing disease, lack of specificity, and insufficient relevance to the pathogenesis of intestinal strictures or incomplete knowledge regarding their operating properties. CONCLUSIONS There is a lack of well-defined studies on biomarkers of intestinal stricture. Development of reliable and accurate biomarkers of stricture is a research priority. Biomarkers can support the clinical management of CD patients and aid in the stratification and monitoring of patients during clinical trials of future antifibrotic drug candidates.

Abstract
BACKGROUND Pain is commonly experienced by patients with inflammatory bowel disease (IBD). Unfortunately, pain management is a challenge in IBD care, as currently available analgesics are associated with adverse events. Our understanding of the impact of opioid use on healthcare utilization among IBD patients remains limited. METHODS A systematic search was completed using PubMed, Embase, the Cochrane Library, and Scopus through May of 2020. The exposure of interest was any opioid medication prescribed by a healthcare provider. Outcomes included readmissions rate, hospitalization, hospital length of stay, healthcare costs, emergency department visits, outpatient visits, IBD-related surgeries, and IBD-related medication utilization. Meta-analysis was conducted on study outcomes reported in at least 4 studies using random-effects models to estimate pooled relative risk (RR) and 95% confidence interval (CI). RESULTS We identified 1969 articles, of which 30 met inclusion criteria. Meta-analysis showed an association between opioid use and longer length of stay (mean difference, 2.25 days; 95% CI, 1.29-3.22), higher likelihood of prior IBD-related surgery (RR, 1.72; 95% CI, 1.32-2.25), and higher rates of biologic use (RR, 1.38; 95% CI, 1.13-1.68) but no difference in 30-day readmissions (RR, 1.17; 95% CI, 0.86-1.61), immunomodulator use (RR, 1.13; 95% CI, 0.89-1.44), or corticosteroid use (RR, 1.36; 95% CI, 0.88-2.10) in patients with IBD. On systematic review, opioid use was associated with increased hospitalizations, healthcare costs, emergency department visits, outpatient visits, and polypharmacy. DISCUSSION Opioids use among patients with IBD is associated with increased healthcare utilization. Nonopioid alternatives are needed to reduce burden on the healthcare system and improve patient outcomes.

Abstract
INTRODUCTION Health researchers from low-income and middle-income countries (LMICs) are under-represented in the academic literature. Scientific writing and publishing interventions may help researchers publish their findings; however, we lack evidence about the prevalence and effectiveness of such interventions. This review describes interventions for researchers in LMICs aimed at strengthening capacity for writing and publishing academic journal articles. METHODS We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to report literature searches in PubMed, Embase, Global Health, Scopus and ERIC. Our keywords included LMICs, low-income and middle-income countries, health research and writing/publication support interventions, with no restrictions on publication date. Our screening process consisted of title screening, abstract review and full-text review. We collected information about the content, implementation and evaluation of each intervention, if included. RESULTS We identified 20 interventions designed to strengthen capacity for scientific writing and publishing. We summarised information from the 14 interventions that reported submitted or published papers as outcomes separately, reasoning that because they provide quantifiable metrics of success, they may offer particular insights into intervention components leading to publication. The writing and publishing components in this 'Publications Reported' group were an average length of 5.4 days compared with 2.5 days in the other group we refer to as 'Other Interventions.' Whereas all 14 Publications Reported interventions incorporated mentors, only two of five in the Other Interventions group incorporated mentors. Across interventions, leaders expressed the importance of a high ratio of mentors to participants, the need to accommodate time demands of busy researchers, and the necessity of a budget for open access fees and high-quality internet connectivity. CONCLUSION Writing and publishing interventions in LMICs are an underutilised opportunity for capacity strengthening. To facilitate the implementation of high-quality interventions, future writing and publishing interventions should share their experiences by publishing detailed information about the approach and effectiveness of the interventions.

Abstract
IMPORTANCE Individuals with chronic pain who use long-term opioid therapy (LTOT) are at risk of opioid use disorder and other harmful outcomes. Rotation to buprenorphine may be considered, but the outcomes of such rotation in this population have not been systematically reviewed. OBJECTIVE To synthesize the evidence on rotation to buprenorphine from full μ-opioid receptor agonists among individuals with chronic pain who were receiving LTOT, including the outcomes of precipitated opioid withdrawal, pain intensity, pain interference, treatment success, adverse events or adverse effects, mental health condition, and health care use. EVIDENCE REVIEW PubMed, CINAHL, Embase, and PsycInfo were searched from inception through November 3, 2020, for peer-reviewed original English-language research that reported the prespecified outcomes of rotation from prescribed long-term opioids to buprenorphine among individuals with chronic pain. Two independent reviewers extracted data as well as assessed risk of bias and study quality according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Quality of evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. FINDINGS A total of 22 studies were analyzed, of which 5 (22.7%) were randomized clinical trials, 7 (31.8%) were case-control or cohort studies, and 10 (45.5%) were uncontrolled pre-post studies, which involved 1616 unique participants (675 female [41.8%] and 941 male [58.2%] individuals). Six of the 22 studies (27.3%) were primary or secondary analyses of a large randomized clinical trial. Participants had diverse pain and opioid use histories. Rationale for buprenorphine rotation included inadequate analgesia, intolerable adverse effects, risky opioid regimens (eg, high dose and/or sedative coprescriptions), and aberrant opioid use. Most protocols were adapted from protocols for initiating treatment in patients with opioid use disorder and used buccal or sublingual buprenorphine. Very low-quality evidence suggested that buprenorphine rotation was associated with maintained or improved analgesia, with a low risk of precipitating opioid withdrawal. Steady-dose buprenorphine was better tolerated than tapered-dose buprenorphine. Adverse effects were manageable, and severe adverse events were rare. Only 2 studies evaluated mental health outcomes, but none evaluated health care use. Limitations included a high risk of bias in most studies. CONCLUSIONS AND RELEVANCE In this systematic review, buprenorphine was associated with reduced chronic pain intensity without precipitating opioid withdrawal in individuals with chronic pain who were receiving LTOT. Future studies are necessary to ascertain the ideal starting dose, formulation, and administration frequency of buprenorphine as well as the best approach to buprenorphine rotation.

Abstract
STUDY OBJECTIVES Head and neck cancers (HNCs) may modify the upper airway anatomy and thereby increase the risk for obstructive sleep apnea (OSA). If untreated, OSA is associated with adverse outcomes. Identification of risk factors for OSA in patients with HNC is essential to promote proper evaluation, treatment, and improvement of sleep-related outcomes. In this review, we assessed associations between tumor stage, cancer treatment, and OSA in the population with HNC. METHODS A systematic search of PubMed, EMBASE (Embase.com), Cochrane Library (Cochranelibrary.com), Scopus, and Web of Science was conducted to identify articles related to OSA in patients with HNC. A total of 215 articles were identified, of which 14 were included in the qualitative synthesis. These studies included 387 participants. RESULTS The most common cancer type, tumor location, and cancer therapy were squamous cell carcinoma, oropharynx, and surgery, respectively. Three of six articles reported an association between surgical treatment and OSA. Conversely, associations between tumor stage, radiotherapy, and OSA were found in only a minority of studies (15%). The prevalence of OSA was between 57% and 76% pre-cancer therapy and 12% and 96% afterward. CONCLUSIONS This review suggests a potential association between HNC surgery and OSA. An association between tumor stage, radiotherapy to the head and neck, and OSA is inconclusive. Further research is needed to examine the relationship between HNC and OSA.

Abstract
Background A peer-led exercise program is one way to empower people sharing similar characteristics to encourage others to be active, but there is a lack of evidence that these programs have physical function and other benefits when delivered to ageing adults. Methods This randomized controlled trial lasting 12 weeks proposed an exercise peer-led program offered to 31 adults aged 50 and above, twice a week, by a trained leader of the same age from March to May 2019. The program was offered for free with limited space and equipment. Valid tests of physical function (e.g., 30-s chair stand, 6-min walk test) were used to assess the functional benefits. Psychosocial outcomes were assessed using self-reported questionnaires and metabolic outcomes via a fasted blood draw. Results A significant difference was found between pre-and post-values in most physical function tests in the intervention group (all p < 0.05). When adjusted for potential confounders, the intervention group was significantly associated with a more significant improvement on the chair stand test (ß = .26; p < 0.001; r2 = 0.26), the arm curl (ß = .29; p < 0.001; r2 = 0.49), as well as the 6-min walk test (ß = -.14; p < 0.001; r2 = 0.62) compared with the control group. Using repetitive measures generalized linear model, the interaction between the changes and the group was significant for all three tests. Benefits were also observed for participants’ stress level and perceived health in the intervention group compared to the control. Finally, no significant difference was observed between groups for metabolic health. Conclusions The current work suggests that a 12-week peer-led exercise program can improve physical function for adults age 50 and above.

Abstract
The hypocretin system consists of two peptides hypocretin-1 and hypocretin-2 (HCRT1 and HCRT2). Hypocretin-containing neurons are located in the posterior and lateral hypothalamus, and have widespread projections throughout the brain and spinal cord. In addition to its presence in the cerebrospinal fluid (CSF), peripheral HCRT1 has been detected in plasma. Robust experimental evidence demonstrates functions of hypothalamic-originated HCRT1 in regulation of multiple biological systems related to sleep-wake states, energy homeostasis and endocrine function. In contrast, HCRT1 studies with human participants are limited by the necessarily invasive assessment of CSF HCRT1 to patients with underlying morbidity. Regulation by HCRT1 of energy homeostasis and reproduction in animals suggests similar regulation in humans and prompts these two systematic reviews. These reviews translate prior experimental findings from animal studies to humans and examine associations between HCRT1 and: 1) metabolic risk factors; 2) reproductive function in men, women and children. A total of 21 studies and six studies met the inclusion criteria for the two searches, respectively. Research question, study design, study population, assessments of HCRT1, reproductive, cardiometabolic data and main findings were extracted. Associations between HCRT1, metabolic and reproductive function are inconsistent. Limitations of studies and future research directions are outlined.

Abstract
In 2014, the library curriculum for the College of Pharmacy was revised, with the number of sessions increased from one per term for two terms to one per term for three terms, instruction was scaffolded, and the flipped classroom model was employed, with active learning and assessments used throughout. This article will describe how the active learning portion of one session was gamified: why a "serious game" was the correct tool to use to improve student learning, how the game was created, and what was the theory underlying this transformation.

Abstract
PURPOSE OF REVIEW Poor sleep is a risk factor for cardiometabolic morbidity. The relationship of sleep and cardiometabolic health could be confounded, mediated, or modified by diet, yet the incorporation of diet in sleep-cardiometabolic health studies is inconsistent. This rapid systematic literature review evaluates the conceptualization of diet as a confounder, mediator, or effect modifier within sleep-cardiometabolic health investigations, and the statistical approaches utilized. RECENT FINDINGS Of 4692 studies identified, 60 were retained (28 adult, 32 pediatric). Most studies included diet patterns, quality, or energy intake as confounders, while a few examined these dietary variables as mediators or effect modifiers. There was some evidence, mostly in pediatric studies, that inclusion of diet altered sleep-cardiometabolic health associations. Diet plays a diverse role within sleep-cardiometabolic health associations. Investigators should carefully consider the conceptualization of diet variables in these relationships and utilize contemporary statistical approaches when applicable.

Abstract
BACKGROUND Covered self-expandable metal stents (SEMS) are utilized for the management of benign and malignant esophageal conditions; however, covered SEMS are prone to migration. Endoscopic suture fixation may mitigate the migration risk of covered esophageal SEMS. Hence, we conducted a systematic review and meta-analysis to evaluate the effectiveness and safety of endoscopic suture fixation for covered esophageal SEMS. METHODS Following PRISMA guidelines, we performed a systematic review from 2011 to 2016 to identify studies (case control/case series) reporting the technical success and migration rate of covered esophageal SEMS following endoscopic suture fixation. We searched multiple electronic databases and conference proceedings. We calculated pooled rates (and 95% confidence intervals [CI]) of technical success and stent migration using a random effects model. RESULTS We identified 14 studies (212 patients) describing covered esophageal SEMS placement with endoscopic suture fixation. When reported, SEMS indications included leak/fistula (n = 75), stricture (n = 65), perforation (n = 10), and achalasia (n = 4). The pooled technical success rate was 96.7% (95% CI 92.3-98.6), without heterogeneity (I 2 = 0%). We identified 29 SEMS migrations at rate of 15.9% (95% CI 11.4-21.6), without heterogeneity (I 2 = 0%). Publication bias was observed, and using the trim-and-fill method, a more conservative estimate for stent migration was 17.0%. Suture-related adverse events were estimated to occur in 3.7% (95% CI 1.6-8.2) of cases. CONCLUSIONS Endoscopic suture fixation of covered esophageal SEMS appears to reduce stent migration when compared to published rates of non-anchored SEMS. However, SEMS migration still occurs in approximately 1 out of 6 cases despite excellent immediate technical success and low risk of suture-related adverse events.

Abstract
Cancer genomic research reveals that a similar cancer clinical phenotype (e.g., non-small cell lung cancer) can arise from various mutations in tumor DNA. Thus, organ of origin is not a definitive classification. Further, targeted therapy for cancer patients (precision oncology) capitalizes on knowledge of individual patient mutational status to deliver treatment directed against the protein products of these mutations with the goal of reducing toxicity and enhancing efficacy relative to traditional nontargeted chemotherapy.

Abstract
Artificial sweeteners (AS) are ubiquitous in food and beverage products, yet little is known about their effects on the gastrointestinal (GI) tract, and whether they play a role in the development of GI symptoms, especially in patients with irritable bowel syndrome. Utilizing the PubMed and Embase databases, we conducted a search for articles on individual AS and each of these terms: fermentation, absorption, and GI tract. Standard protocols for a systematic review were followed. At the end of our search, we found a total of 617 eligible papers, 26 of which were included. Overall, there is limited medical literature available on this topic. The 2 main areas on which there is data to suggest that AS affect the GI tract include motility and the gut microbiome, though human data is lacking, and most of the currently available data is derived from in vivo studies. The effect on motility is mainly indirect via increased incretin secretion, though the clinical relevance of this finding is unknown as the downstream effect on motility was not studied. The specific effects of AS on the microbiome have been conflicting and the available studies have been heterogeneous in terms of the population studied and both the AS and doses evaluated. Further research is needed to assess whether AS could be a potential cause of GI symptoms. This is especially pertinent in patients with irritable bowel syndrome, a population in whom dietary interventions are routinely utilized as a management strategy.

Abstract
Diabetic neuropathy is the most common microvascular complication of diabetes mellitus with high morbidity and mortality, and low quality of life. It has a broad spectrum of clinical forms, although distal symmetrical polyneuropathy is the most prevalent. Several oral complications including burning mouth syndrome, dry mouth, and impairment of the senses taste and smell are less-known manifestations of diabetic neuropathy and often overlooked. Periodontitis, tooth loss, and temporomandibular joint dysfunction may be also present in these patients and are equally debilitating. Periodontitis was declared the sixth complication of diabetes in 1993 and may contribute to poor glucose control. Hence, periodontitis and diabetes mutually and adversely affect each other. This review summarizes the available body of scientific literature that discusses oral manifestations in patients with diabetic neuropathy and identifies important areas where more research is needed.

Abstract
11068 Background: The primary objective of this study was to estimate the proportion of chemotherapy dose delays in a dose- dense regimen consisting of A (60mg/m2), C (600 mg/m2) x 4 cycles q2 weeks followed by T (175 mg/m2) G (1g/m2) x 4 cycles q2w with pegfilgrastim (6 mg/m2 sc d2) and darbepoetin-alfa (2.25 microg/kg if Hb < 110g/L) as treatment for patients with high-risk early stage breast cancer. Dose delay was defined by the proportion of subjects experiencing delay = 7 days in any cycle. Entry criteria path stage IIA-IIIA breast adenocarcinoma; node positive patients > 6 axillary lymph nodes removed or sentinel LN biopsy positive for metastasis. Treatment commenced within 8 weeks. Secondary endpoints included proportion of delays by cycle, causes of delay by cycle, causes of dose reduction by cycle, as well as time to haematological engraftment. Patients underwent weekly FBC, electrolytes, LFTs, with a normal baseline echo assessment. Herceptin therapy was approved in Australia 1st October 2006 and was added to TG therapy for FISH/CISH/IHC 3+ positive patients. All patients completed FACT-F QOL forms. The half-width confidence interval to predict for delay based on the AC-T data is 0.17 for n = 20 patients. Results: Twenty (20) women; median age 50 (41–66) met the criteria for treatment. No patients had treatment delays ≥ 2 days for any reason. One (5%) patient underwent a blood transfusion for a rapid decline in haemoglobin (Hb) prior to darbepoetin therapy. One (5%) patient was admitted for uncontrolled vomiting. Seven (35%) patients received darbepoetin therapy without secondary Hb rise above 130 g/L. One (5%) patient had a 20% dose reduction in A dose due to mucositis. For nausea >G1 aprepitant therapy was added. There have been no dose modifications due to hepatic toxicity. Final cycle, QOL and pharmacogenomic data will be presented at the meeting. [Table: see text] No significant financial relationships to disclose.

Abstract
OBJECTIVE To compare the efficacy, adverse effects and acceptability of the three most common misoprostol regimens used with mifepristone for medical abortion. DESIGN Randomised nonblinded trial. SETTING Three clinics associated with major research universities in Canada; two in major urban areas and one in a periurban area. POPULATION Women of reproductive age. METHODS Consenting women presenting for abortion services with gestations less than 56 days and who met inclusion criteria were given 200 mg mifepristone orally and then randomised into three misoprostol study groups: (group I) 400 micrograms of oral misoprostol, (group II) 600 micrograms of oral misoprostol, and (group III) 800 micrograms of vaginal misoprostol. Misoprostol was self-administered at home 24-48 hours following mifepristone, and participants were instructed to take a second similar misoprostol dose at 24 hours after the initial dose if bleeding was less than a normal menstrual period. MAIN OUTCOME MEASURES Successful abortion without surgery was 94.1%, with no significant differences across the three study groups (94.7% in group I, 93.4% in group II, and 94.3% in group III; P= 0.975). RESULTS Efficacy and adverse effects did not differ significantly across the three study groups. Pain increased significantly across the study and the gestational age groups and was associated with lower acceptability. CONCLUSIONS There appears to be a range of safe and effective options for early medical abortion with mifepristone including a choice between oral and vaginal administration of misoprostol.

Abstract
18591 Background: Chemotherapy-induced nausea and vomiting (CINV) remains a significant issue for patients, especially management of delayed symptoms. The Perugia 2004 antiemetic guidelines recommended that anthracycline/cyclophosphamide (A/C) combination regimens be considered as high risk emetogenic potential. The aim of our study was to determine the extent of CINV, and effect on quality of life for chemotherapy-naïve patients in a practice-based environment. Methods: Eligible patients were receiving their 1st cycle of high risk emetogenic or carboplatin chemotherapy, administered with “standard care” (5HT3 antagonist + dexamethasone) antiemetics (use of NK1 antagonists excluded). Patients completed a daily diary for 5 days post chemotherapy, capturing data on CINV activity and rescue medications usage. Emesis and nausea-specific health status was measured by the Functional Living Index - Emesis (FLIE); general health status was assessed using a 100mm VAS (EQVAS). Results: Of 74 patients, 42 received an A/C regimen, 16 cisplatin and 16 carboplatin. Overall complete response (no vomiting, no use of rescue antiemetics during the study period) was 60% in patients receiving carboplatin, 24% A/C and 21% cisplatin. During the delayed phase, mean total emesis episodes for carboplatin was 0.6, A/C 2.21 and cisplatin 4.08. Patients receiving carboplatin reported less delayed nausea, and better outcomes for FLIE and EQVAS scores. Treatment with either A/C or cisplatin was associated with similar deterioration in nausea control across the study period, and similar impact on FLIE scores (see table ). Conclusions: Our results are consistent with the recommendation that A/C regimens be considered highly emetogenic, with similar impact on patient symptoms and quality of life compared with cisplatin. Delayed CINV remains a target for antiemetic intervention. Similar studies need to be repeated in patients receiving additional NK1 antagonists to assess their impact on CINV outside clinical trials.

Abstract
OBJECTIVE To assess knowledge of abortion legislation and knowledge and attitudes about medical and surgical abortion among women seeking a legal abortion in Latvia. METHODS Data are drawn from a survey of 371 abortion clients from 16 purposively selected abortion clinics in Latvia. A semi-structured questionnaire was used to collect socio-demographic data and information on women's knowledge of and attitudes toward abortion law and abortion methods. RESULTS Most women knew that abortion is legal either under any (53%) or certain (37%) circumstances. Almost one third (31%) of women interviewed were aware of medical abortion. After hearing a description of medical abortion, respondents felt the method as described would be advantageous because it could avoid a surgical intervention (33%) or found it simple, easy, convenient, or natural (12%). Women were concerned that the method might not be completely effective (38%) or be associated with side-effects (22%). CONCLUSIONS Respondents were interested in medical abortion as a less invasive option to surgical abortion. Efforts should be undertaken to inform women about the safety and efficacy of the method.

Abstract
BACKGROUND Studies in rodents demonstrate sex differences in neuroendocrine stress axis activity after treatment with alcohol. In abstinent alcoholics, atypical depressives, and individuals with posttraumatic stress disorder, limbic-hypothalamic-pituitary-adrenal (LHPA)-axis activity is often blunted; among females in these patient populations, however, resistance to glucocorticoid feedback and increased pituitary reactivity is observed. Early parental loss is a major life stressor and is a risk factor for both affective disturbances and LHPA-axis abnormalities later in life. We wanted to determine whether sex and early life parental absence would interact to influence alcohol-induced alterations in LHPA-axis activity after exposure to ethanol in macaques. METHODS Animals were reared with their mothers in social groups (MR, n = 94) or without adults in peer-only groups (PR, n = 79). At 5 years of age, they received an intravenous infusion of alcohol (2-2.2 g/kg), and the effects of alcohol, sex, and rearing condition on ACTH and cortisol levels were analyzed by ANOVA. RESULTS Peer-reared females had higher ACTH levels than did PR males, MR females, and MR males after alcohol infusion. Alcohol-induced cortisol levels were not affected by sex and rearing condition. CONCLUSIONS These findings suggest that there are sex differences in glucocorticoid negative feedback, pituitary responsivity, or release of ACTH secretagogues among individuals exposed to early life stress and emphasize the importance of considering sex effects when studying LHPA-axis dysregulation in alcoholism and other stress-related neuropsychiatric disorders.

Abstract
Breast cancer is very rare in adolescents and very young women. Less than 1% of all breast cancer cases occur before the age of 30 years (Natl Cancer Inst Monogr 16 (1994) 69). Invasive breast cancer occurring in women before the age of 35 years has a more aggressive biological behaviour and is associated with a worse prognosis than in older premenopausal women. Breast cancers in these young women are more frequently poorly differentiated, oestrogen-receptor (ER)-negative, have lymphovascular invasion and high proliferating fractions. Breast-conserving surgery in women <35 years old is associated with a higher risk of local recurrence than in older women. All young women should be considered at moderate-high risk by virtue of their age alone and offered adjuvant therapy. The long-term toxicity of adjuvant therapies is a particular concern when treating these women. The implications of possible fertility impairment and premature menopause require consideration when discussing adjuvant chemotherapy and endocrine therapy. Adolescents and young women are particularly vulnerable to emotional distress and psychosocial problems and should be provided with appropriate support. Young women who are at a potential high-risk of developing breast cancer such as those with germline mutations of BRCA1, BRCA2, TP53, PTEN or who have previously received mantle irradiation for Hodgkin's disease need close follow-up and are candidates for screening from a young age.

Abstract
Purpose: Theoretically, patients with early breast cancer might benefit from starting adjuvant chemotherapy soon after surgery, and this would have important clinical implications. We have addressed this question from a large, single-center database in which the majority of patients received anthracyclines. Patients and Methods: A total of 1,161 patients from a prospectively maintained database treated with adjuvant chemotherapy for early breast cancer at the Royal Marsden Hospital (London, United Kingdom), including 686 (59%) receiving anthracyclines, were retrospectively analyzed. The disease-free survival (DFS) and overall survival (OS) of the 368 patients starting chemotherapy within 21 days of surgery (group A) were compared with those of the 793 patients commencing chemotherapy ≥ 21 days after surgery (group B). Median follow-up time was 39 months (range, 12 to 147 months). Results: No significant difference in 5-year DFS was found between the two groups overall (70% for group A v 72% for group B; P = .4) or in any subgroup. Likewise, there was no difference in 5-year OS (82% for group A v 84% for group B; P = .2) or when the interval to the start of chemotherapy was considered as a continuous variable (P = .4). Conclusion: We have been unable to identify any significant survival benefit from starting adjuvant chemotherapy early after surgery, either overall or in any subset of patients.

Abstract
A polymorphism in the serotonin (5-HT) transporter gene regulatory region (5-HTTLPR) is associated with measures of 5-HT transporter (5-HTT) expression and 5-HT-mediated behaviors in humans. An analogous length variation of the 5-HTTLPR has been reported in rhesus monkeys (rh5-HTTLPR). A retrospective association study was conducted on 115 rhesus macaque infants either homozygous for the long 5HTTLPR variant (l/l) or heterozygous for the short and long form (l/s). To assess contributions of genotype and early rearing environment, 36 mother-reared monkeys (l/l = 26, l/s = 10) and 79 nursery-reared monkeys (l/l = 54, l/s = 25) were assessed on days 7, 14, 21, and 30 of life on a standardized primate neurobehavioral test designed to measure orienting, motor maturity, reflex functioning, and temperament. Both mother-reared and nursery-reared heterozygote animals demonstrated increased affective responding relative to l/l homozygotes. Nursery-reared, but not mother-reared, l/s infants exhibited lower orientation scores than their l/l counterparts. These results demonstrate the contributions of rearing environment and genetic background, and their interaction, in a nonhuman primate model of behavioral development.

Abstract
PURPOSE To evaluate the activity and toxicity of gemcitabine and carboplatin in consecutive patients presenting with locally advanced or metastatic transitional cell carcinoma of the urothelium (TCC). PATIENTS AND METHODS Seventeen consecutive patients referred to a single institution with locally advanced or metastatic TCC were treated with carboplatin AUC 5 on day 1 and gemcitabine 1000 mg/m2 on day 1 and 8 of a 21-day cycle. All patients were assessable for response and toxicity. Minimal eligibility criteria were used to minimize patient selection. RESULTS Seventeen patients with measurable stage IV TCC of the urothelium were treated. The median age was 69 years (range 54-78), the median creatinine clearance was 56 ml/min (range 34-90) and 30% of patients had an ECOG performance score of two. Nine patients (53%) had visceral metastases and the majority of patients had multiple sites of metastases. There were three complete responses, seven partial responses, for an overall response rate of 58.8%. Responses were seen at all sites including the liver. One patient had a response within a previously irradiated field and three patients with prior chemotherapy had responses. Median overall survival was 10.5 months and median time to progression was 4.6 months. Toxicity was primarily haematologic with six patients having grade 3 neutropenia and six patients with grade 4 neutropenia. There were five cases of grade 3 and three cases of grade 4 thrombocytopenia. There were no episodes of febrile neutropenia and only one patient required admission for management of toxicity. Thirteen patients required dose reduction or delay due to neutropenia or thrombocytopenia. There were no treatment-related deaths. CONCLUSION The combination of carboplatin and gemcitabine is active in metastatic transitional cell carcinoma of the urothelium with manageable toxicity in a relatively elderly group of patients with some poor prognostic features.

Abstract
Data on the prevalence of asthma in children residing in remote indigenous communities in Australia are sparse, despite the many reports of high prevalence in nonindigenous children of this country. Two previous Australian studies have had poor participation rates, limiting interpretation of their results. A study of children in the Torres Strait and Northern Peninsula Area of Australia was conducted to document the prevalence of asthma symptoms. Five indigenous communities were randomly selected and trained interviewers, who were local indigenous health workers, recruited participants using a house-by-house approach. Information was collected by a structured face-to-face interview based on a standardized questionnaire constructed from the protocol International Study of Asthma and Allergy in Childhood; 1,650 children were included in the study with a 98% response rate. Overall, the prevalence of self-reported ever wheezing was 21%; 12% reported wheezing in the previous year; and 16% reported ever having asthma. There was significant variation in the prevalence of asthma symptoms between communities. It is concluded that there are significant intercommunity variations in the prevalence of asthma symptoms in remote communities and that the prevalence in these communities is as high as in nonindigenous groups.

Abstract
Accurate health information is a key component in the development of health improvement strategies. This paper provides a discussion of the challenges in improving hospital information systems in relation to indigenous patients. Based on interviews with both staff and patients of a major city hospital complex, a picture emerges of the need for bottom-up approaches to understanding perceptions of identity. Indigenous patients were found to be generally comfortable about identifying themselves on hospital records (if asked), but were often not clear why such questions were asked. On the other hand hospital staff were often uncomfortable about asking and were equally not always clear why such information was needed. Issues of accurate hospital record administration are discussed in relation to the attitudes and perceptions of both staff and patients.
