Prognosis after neoadjuvant chemoradiation or chemotherapy for locally advanced gastro-oesophageal junctional adenocarcinoma.

BACKGROUND: Trials typically group cancers of the gastro-oesophageal junction (GOJ) with oesophageal or gastric cancer when studying neoadjuvant chemoradiation and perioperative chemotherapy, so the results may not be fully applicable to GOJ cancer. Because optimal neoadjuvant treatment for GOJ cancer remains controversial, outcomes with neoadjuvant chemoradiation versus chemotherapy for locally advanced GOJ adenocarcinoma were compared retrospectively. METHODS: Data were collected from all patients who underwent neoadjuvant treatment followed by surgery for adenocarcinoma located at the GOJ at a single high-volume institution between 2002 and 2017. Postoperative major complications and mortality were compared between groups using Fisher's exact test. Overall survival (OS) and disease-free survival (DFS) were assessed by log rank test and multivariable Cox regression analyses. Cumulative incidence functions were used to estimate recurrence, and groups were compared using Gray's test. RESULTS: Of 775 patients, 650 had neoadjuvant chemoradiation and 125 had chemotherapy. These groups were comparable in terms of clinical tumour and lymph node categories, although the chemoradiation group had greater proportions of white men, complete pathological response to chemotherapy, and smaller proportions of diffuse cancer, poor differentiation, and neurovascular invasion. Postoperative major complications (20.0 versus 17.6 per cent) and 30-day mortality (1.7 versus 1.6 per cent) were not significantly different between the chemoradiation and chemotherapy groups. After adjustment, type of therapy (chemoradiation versus chemotherapy) was not significantly associated with OS (hazard ratio (HR) 1.26, 95 per cent c.i. 0.96 to 1.67) or DFS (HR 1.27, 0.98 to 1.64). Type of recurrence (local, regional, or distant) did not differ after neoadjuvant chemoradiation versus chemotherapy. CONCLUSION: In patients undergoing surgical resection for locally advanced adenocarcinoma of the GOJ, OS and DFS did not differ significantly between patients who had neoadjuvant chemoradiation compared with chemotherapy.

Treating advanced cancer of the gastro-oesophageal junction (GOJ) poses a challenge given its location in the distal oesophagus and proximal stomach, and whether it should be treated as oesophageal or gastric cancer. Given the indistinct location, it is unclear whether GOJ cancer should be treated with neoadjuvant chemoradiation, which is the treatment of choice for advanced oesophageal cancers, or perioperative chemotherapy, which is the treatment of choice for advanced gastric cancers. Few studies have addressed treatment options specifically for GOJ cancers. This study investigated whether there was a difference in survival between patients with GOJ cancer who were treated with chemoradiation versus chemotherapy.

Effects of Zentangle art workplace health promotion activities on rural healthcare workers.

OBJECTIVES: Workplace health promotion activities have a positive effect on emotions. Zentangle art relaxes the body and mind through the process of concentrating while painting, achieving a healing effect. This study aimed to promote the physical and mental health of rural healthcare workers through Zentangle art-based intervention. STUDY DESIGN: This was a quasi-experimental pilot study. METHODS: A Zentangle art workshop was held from November 2019 to July 2020. A total of 40 healthcare workers were recruited. The participants were asked to provide baseline data, and the Brief Symptom Rating Scale (BSRS-5), work stress management effectiveness self-rating scale, General Self-Efficacy Scale (GSES), and Workplace Spirituality Scale (WSS) were administered before and after the workshop. SPSS 22.0 statistical package software was used to conduct the data analysis. RESULTS: The median age (interquartile range [IQR]) was 32.00 years (23.00-41.75 years). The Wilcoxon signed-rank test revealed that the median (IQR) BSRS-5 postintervention score was 4.0 (1.25-5.0), which was lower than the preintervention score (P = 0.004). The postintervention score for the work stress management effectiveness self-rating scale was 36.5 (31.0-40.0), which was also lower than the preintervention score (P = 0.009). A higher score for the GSES or WSS indicated improvements in stress management and self-efficacy. The GSES postintervention score 25.00 (21.0-30.75) was significantly higher than the preintervention score (P = 0.010), and the WSS postintervention score 104.0 (88.0-111.75) was significantly higher than the preintervention score (P = 0.005). CONCLUSIONS: The study provides evidence that painting therapy can effectively relieve stress, reduce workplace stress and frustration, enhance self-efficacy, and increase commitment to work among healthcare workers, thus improving their physical, mental, and spiritual well-being. Zentangle art provides employees with multiple channels for expressing their emotions and can improve the physical and mental health of healthcare workers in the workplace. It is beneficial and cost-effective and can serve as a benchmark for peer learning.

Ustekinumab for the treatment of moderate-to-severe plaque psoriasis in paediatric patients (≥ 6 to < 12 years of age): efficacy, safety, pharmacokinetic and biomarker results from the open-label CADMUS Jr study.

BACKGROUND: Limited options are available for treatment of paediatric psoriasis. OBJECTIVES: To evaluate the efficacy and safety of ustekinumab in paediatric patients with psoriasis (≥ 6 to < 12 years of age). METHODS: CADMUS Jr, a phase III, open-label, single-arm, multicentre study, evaluated ustekinumab in paediatric patients with moderate-to-severe plaque psoriasis. Patients received weight-based dosing of ustekinumab (< 60 kg: 0·75 mg kg-1 ; ≥ 60 to ≤ 100 kg: 45 mg; > 100 kg: 90 mg) administered by subcutaneous injection at weeks 0 and 4, then every 12 weeks through week 40. Study endpoints (all at week 12) included the proportions of patients achieving a Physician's Global Assessment score of cleared/minimal (PGA 0/1) and ≥ 75%/90% improvement in Psoriasis Area and Severity Index (PASI 75/90), and change in Children's Dermatology Life Quality Index (CDLQI). Serum ustekinumab concentrations, antidrug antibodies and cytokine levels were measured through week 52. Safety was evaluated through week 56. RESULTS: In total, 44 patients (median age 9·5 years) received at least one dose of ustekinumab. Three patients discontinued the study agent through week 40. At week 12, 77% of patients achieved PGA 0/1, 84% achieved PASI 75 and 64% achieved PASI 90 response. The mean change in CDLQI was -6·3. Trough serum ustekinumab concentrations reached steady state at weeks 28-52. The incidence of antidrug antibodies was 10% (n = 4). Mean serum concentrations of interleukin-17A/F and interleukin-22 were significantly reduced at weeks 12 and 52. Overall, 34 patients (77%) had at least one adverse event and three (7%) had a serious adverse event. CONCLUSIONS: Ustekinumab effectively treated moderate-to-severe psoriasis in paediatric patients, and no new safety concerns were identified. What is already known about this topic? Ustekinumab is approved for use in adolescents (≥ 12 to < 18 years of age) and adults (≥ 18 years) with moderate-to-severe psoriasis. What does this study add? Ustekinumab effectively treats moderate-to-severe psoriasis in paediatric patients (≥ 6 to < 12 years of age), with no new safety concerns. Linked Comment: Reich. Br J Dermatol 2020; 183:606-607.

Tofacitinib in psoriatic arthritis patients: skin signs and symptoms and health-related quality of life from two randomized phase 3 studies.

BACKGROUND: Psoriatic arthritis (PsA) is a chronic, systemic immune-mediated inflammatory musculoskeletal disease. The onset of dermatologic symptoms often precedes rheumatic manifestations. Tofacitinib is an oral Janus kinase inhibitor for the treatment of PsA that has been shown to improve dermatologic symptoms in patients with PsA. OBJECTIVES: To investigate the efficacy of tofacitinib in improving dermatologic endpoints in adult patients with active PsA. METHODS: This analysis included data from two placebo-controlled, double-blind, phase 3 studies in patients with active PsA and an inadequate response (IR) to ≥1 conventional synthetic disease-modifying antirheumatic drug (csDMARD) who were tumor necrosis factor inhibitor (TNFi)-naïve (OPAL Broaden; NCT01877668) or an IR to ≥1 TNFi (OPAL Beyond; NCT01882439). Patients had active plaque psoriasis at screening and received a stable dose of one csDMARD during the study. Patients were randomized to tofacitinib 5 mg twice daily (BID), 10 mg BID, adalimumab 40 mg subcutaneous injection once every 2 weeks (OPAL Broaden only) or placebo (to Month 3). Dermatologic endpoints: Psoriasis Area and Severity Index (PASI) total score; PASI90 overall; PASI75 and PASI90 by baseline PASI severity; Physician's Global Assessment of Psoriasis; Nail Psoriasis Severity Index; Dermatology Life Quality Index total and sub-dimension scores; Itch Severity Item; and Patient's Global Joint and Skin Assessment-Visual Analog Scale-Psoriasis question. RESULTS: In patients with active PsA, including those stratified by mild or moderate/severe dermatologic symptoms, greater improvements from baseline and percentage of responders were observed in tofacitinib-treated patients vs. placebo for the majority of analyzed dermatologic endpoints at Months 1 and 3, and improvements were maintained to Month 12 in OPAL Broaden and Month 6 in OPAL Beyond. Similar effects were observed in adalimumab-treated patients vs. placebo in OPAL Broaden across dermatologic endpoints. CONCLUSIONS: Tofacitinib provides a treatment option for patients with active PsA, including the burdensome dermatologic symptoms of PsA.

Outpatient dermatology consultations for oncology patients with acute dermatologic adverse events impact anticancer therapy interruption: a retrospective study.

BACKGROUND: Dermatologic adverse events (dAEs) of anticancer therapies may negatively impact dosing and quality of life. While therapy interruption patterns due to dAEs have been studied in hospitalized cancer patients, similar outcomes in outpatient oncodermatology are lacking. OBJECTIVES: To analyse the therapy interruption patterns, clinico-histopathologic characteristics and management outcomes of outpatient dermatology consultations for acute dAEs attributed to the most frequently interrupted class of oncologic agents. METHODS: We performed a retrospective cohort study of all cancer patients who received a same-day outpatient dermatology consultation for acute dAEs at our institution from 1 January to 30 June 2015. Relevant data were abstracted from electronic medical records, including demographics, oncologic history and explicit recommendations by both the referring clinician and consulting dermatologist on anticancer therapy interruption. Consultations with the most frequently interrupted class of oncologic treatment were characterized according to clinico-histopathologic features, dermatologic management and clinical outcomes. RESULTS: There were 426 same-day outpatient dermatology consultations (median age 59, 60% female, 30% breast cancer), of which 295 (69%) had systemic anticancer therapy administered within 30 days prior. There was weak inter-rater agreement between referring clinicians and consulting dermatologists on interruption of anticancer treatment (n = 150, κ = 0.096; 95% CI -0.02 to 0.21). Seventy-three (25%) consultations involved interruption by the referring clinician, most commonly targeted therapy (24, 33%). Maculopapular rash was commonly observed in 23 consultations with 25 dAEs attributed to targeted agents (48%), and topical corticosteroids were most frequently utilized for management (22, 38%). The majority (83%) of consultations with targeted therapy-induced dAEs responded to dermatologic treatment and 84% resumed oncologic therapy, although three (19%) at a reduced dose. Rash recurred only in two instances (13%). CONCLUSIONS: A high frequency of positive outcomes in the management of targeted therapy-induced dAEs by outpatient consulting dermatologists and low recurrence of skin toxicity suggests impactful reductions in interruption of anticancer therapy.

The Global Leadership Mentoring Community: building capacity across seven global regions.

AIM: The purpose of this paper is to report on the evaluation of the online Global Leadership Mentoring Community, a programme designed to build relationships across seven global regions and promote leadership development for emerging nurse leaders. BACKGROUND: There is a pressing need and opportunity for sustainable global leadership mentoring programmes. This programme of Sigma Theta Tau International (Sigma) brought mentors and mentees together from across the world to build leadership capacity, understand global leadership issues and build networks. Community coordinators purposively selected mentors from each of Sigma's seven Global Regions, and mentees were chosen through a process of snowball sampling. Mentors and mentees met monthly with quarterly group calls. METHODS: The study followed a programme evaluation, outcomes-focused approach. All eleven pairs of mentors-mentees were invited to complete online surveys at the outset and end of programme capturing both quantitative and qualitative data. Quantitative data were analysed using descriptive statistics and for qualitative data, a thematic analysis. FINDINGS: Quantitative data confirmed that all 22 participants gained from the experience. From qualitative analysis, themes emerged illustrating the scope of achievements: 1. facilitation of successful outcomes for both mentors and mentees, 2. challenges of global mentoring and 3. strategies for successful global mentoring. DISCUSSION/CONCLUSION: Participants reported that creating global leadership is a longitudinal process that needs sustained attention to effect change. This evaluation identified many strengths of the programme and recommended its continuation to help further development of global leaders, particularly through focusing more purposefully on policy issues. IMPLICATIONS FOR NURSING POLICY: Empowerment of nurses globally through a Global Leadership Mentoring Community can improve leadership at all levels, thus emboldening their voices to influence nursing and health policy and ultimately improve patient care.

Fetal fraction-based risk algorithm for non-invasive prenatal testing: screening for trisomies 13 and 18 and triploidy in women with low cell-free fetal DNA.

OBJECTIVE: To identify pregnancies at increased risk for trisomy 13, trisomy 18 or triploidy attributable to low fetal fraction (FF). METHODS: A FF-based risk (FFBR) model was built using data from more than 165 000 singleton pregnancies referred for single-nucleotide polymorphism (SNP)-based non-invasive prenatal testing (NIPT). Based on maternal weight and gestational age (GA), FF distributions for normal, trisomy 13, trisomy 18 and triploid pregnancies were constructed and used to adjust prior risks for these abnormalities. A risk cut-off of ≥ 1% was chosen to define pregnancies at high risk for trisomy 13, trisomy 18 or triploidy (high FFBR score). The model was evaluated on an independent blinded set of pregnancies for which SNP-based NIPT did not return a result, and for which pregnancy outcome information was gathered retrospectively. RESULTS: The evaluation cohort comprised 1148 cases, of which approximately half received a high FFBR score. Compared with rates expected based on maternal age (MA) and GA, cases with a high FFBR score had a significantly increased rate of trisomy 13, trisomy 18 or triploidy combined (5.7% vs 0.7%; P < 0.001) and also of unexplained pregnancy loss (14.7% vs 10.4%; P < 0.001). For cases that did not receive a high FFBR score, the incidence of a chromosomal abnormality or pregnancy loss was not significantly different from that expected based on MA and GA. In this study cohort, the sensitivity of the FFBR model for detection of trisomy 13, trisomy 18 or triploidy was 91.4% (95% CI, 76.9-98.2%) with a positive predictive value of 5.7% (32/564; 95% CI, 3.9-7.9%). CONCLUSIONS: For pregnancies with a FF too low to receive a result on standard NIPT, the FFBR algorithm identified a subset of cases at increased risk for trisomy 13, trisomy 18 or triploidy. For the remainder of cases, the risk of a fetal chromosomal abnormality was unchanged from that expected based on MA and GA. © 2018 The Authors.

Long-term outcome of 487 patients with early-stage extra-nodal marginal zone lymphoma.

BACKGROUND: Localized early-stage extra-nodal marginal zone lymphoma (MZL) presents with heterogeneous organ involvement and is treated with various modalities, including resection, radiotherapy, and systemic therapy. We report the long-term outcome of a large cohort of extra-nodal MZL and assess the impact of patient and disease characteristics, organ site, and treatment strategy on disease control and survival. PATIENTS AND METHODS: We identified 487 consecutive patients with stage IE or IIE MZL referred between 1992 and 2012 to Memorial Sloan Kettering Cancer Center. Pathology was reviewed by hematopathologists at our institution. Patient and disease factors as well as treatment types were analyzed for association with relapse-free survival, overall survival, and cumulative incidence of relapse. RESULTS: Median follow-up after treatment was 4.7 years. Five-year relapse-free survival and overall survival were 60% and 89%, respectively. Cumulative incidence of disease-specific death at 5 years was 1.3%. Radiotherapy alone was the initial treatment in 50% of patients, followed by surgical resection (30%), observation (8%), immunotherapy (4%), and chemotherapy (2%). Initial treatment type, primary disease site, and number of involved sites were significant factors in multivariable analysis of relapse (all P < 0.05). When compared with stomach, MZL originating in other disease sites (HR > 2.0, P ≤ 0.001), except for thyroid, had higher risk of relapse. Strategies such as antibiotics or topical therapies were associated with higher risk of relapse when compared with radiation therapy (P < 0.001). Crude rate of transformation to pathologically confirmed large-cell lymphoma was 2% (11 patients). CONCLUSION: Overall and cause-specific survival are high in early-stage extra-nodal MZL. Curative-intent treatment led to fewer relapses and reduced the need for salvage. Stomach cases had lower risk of relapse than other anatomic primary sites. This study supports the use of local therapies to treat stage IE and IIE MZL.

Extension of ustekinumab maintenance dosing interval in moderate-to-severe psoriasis: results of a phase IIIb, randomized, double-blinded, active-controlled, multicentre study (PSTELLAR).

BACKGROUND: Phase III studies showed that some patients maintained response for ≥ 6 months following ustekinumab discontinuation. OBJECTIVES: To assess clinical responses with extended ustekinumab maintenance dosing intervals. METHODS: Adults with moderate-to-severe plaque psoriasis received ustekinumab at weeks 0, 4 and 16 during open-label treatment. Patients achieving a week-28 Physician's Global Assessment (PGA) score of cleared/minimal (PGA = 0/1) were randomized 1 : 4 to group 1 [approved every 12 weeks (q12 wk) maintenance] or group 2 (q12-24 wk; response-based dosing determined by time to loss of PGA = 0/1). Key end points included the number of visits with PGA = 0/1 (primary end point) and ≥ 75% improvement in Psoriasis Area and Severity Index (PASI 75) between weeks 88 and 112, and PGA/PASI responses between weeks 28 and 112. RESULTS: Overall, 378 patients achieved PGA = 0/1 at week 28 and were randomized to group 1 (n = 76) or group 2 (n = 302). Patients in group 1 had numerically greater mean numbers of visits with PGA = 0/1 than group 2 and also with PASI 75 from week 88 to 112. A higher proportion of patients in group 1 (55%) than group 2 (39%) had PGA = 0/1 at all seven visits from week 88 to 112. Maintenance of response was observed with dose-interval extension beyond q12 wk in a subset of patients. Extending the dosing interval did not affect antibody development or safety. CONCLUSIONS: Efficacy was better maintained among week-28 PGA responders randomized to continue q12 wk ustekinumab vs. extending maintenance dosing based on clinical response, although some patients maintained high levels of efficacy with up to q24 wk dosing.

Pre-stroke physical activity is associated with fewer post-stroke complications, lower mortality and a better long-term outcome.

BACKGROUND AND PURPOSE: Physical activity is associated with a reduced incidence of first-time stroke. However, few studies have examined the effect of pre-stroke physical activity on post-stroke complications and clinical outcomes. METHODS: A total of 39 835 cases of stroke registered in the nationwide stroke registry system of Taiwan between 2006 and 2009 were analyzed according to five levels of severity as determined by National Institutes of Health Stroke Scale score upon hospital admission. Pre-stroke physical activity was defined in the Taiwan Stroke Registry as dedicated leisure-time physical activity for at least 30 min/day for 3 days/week for more than 6 months. A Cox model was used to compare complications and outcomes between active and inactive groups. RESULTS: The active and inactive groups were similar in age distribution and stroke type distribution, but the active group had better National Institutes of Health Stroke Scale scores upon admission. The active group also had significantly fewer post-stroke complications. Active patients had lower hospital mortality and better functional outcomes upon discharge as per the modified Rankin Scale. Improved functional status in the active group was significant at 1, 3 and 6 months post-stroke. CONCLUSION: Dedicated leisure-time physical activity for at least 30 min/day, at least three times per week for more than 6 months was associated with decreased stroke severity, fewer post-stroke complications, lower mortality and better outcomes.

A prospective study of total plasma cell-free DNA as a predictive biomarker for response to systemic therapy in patients with advanced non-small-cell lung cancers.

BACKGROUND: While previous studies have reported on the prognostic value of total plasma cell-free deoxyribonucleic acid (cfDNA) in lung cancers, few have prospectively evaluated its predictive value for systemic therapy response. PATIENTS AND METHODS: We conducted a prospective study to evaluate the association between changes in total cfDNA and radiologic response to systemic therapy in patients with stage IIIB/IV non-small-cell lung cancers (NSCLCs). Paired blood collections for cfDNA and computed tomography (CT) assessments by RECIST v1.0 were performed at baseline and 6-12 weeks after therapy initiation. Total cfDNA levels were measured in plasma using quantitative real-time polymerase chain reaction. Associations between changes in cfDNA and radiologic response, progression-free survival (PFS), and overall survival (OS) were measured using Kruskal-Wallis and Kaplan-Meier estimates. RESULTS: A total of 103 patients completed paired cfDNA and CT response assessments. Systemic therapy administered included cytotoxic chemotherapy in 57% (59/103), molecularly targeted therapy in 17% (17/103), and combination therapy in 26% (27/103). Median change in cfDNA from baseline to response assessment did not significantly differ by radiologic response categories of progression of disease, stable disease and partial response (P = 0.10). However, using radiologic response as continuous variable, there was a weak positive correlation between change in radiologic response and change in cfDNA (Spearman's correlation coefficient 0.21, P = 0.03). Baseline cfDNA levels were not associated with PFS [hazard ratio (HR) = 1.06, 95% confidence interval (CI) 0.93-1.20, P = 0.41] or OS (HR = 1.04, 95% CI 0.93-1.17, P = 0.51), neither were changes in cfDNA. CONCLUSIONS: In this large prospective study, changes in total cfDNA over time did not significantly predict radiologic response from systemic therapy in patients with advanced NSCLC. Pretreatment levels of total cfDNA were not prognostic of survival. Total cfDNA level is not a highly specific predictive biomarker and future investigations in cfDNA should focus on tumor-specific genomic alterations using expanded capabilities of next-generation sequencing.

CT-guided percutaneous core-needle biopsy of pancreatic masses: comparison of the standard mesenteric/retroperitoneal versus the trans-organ approaches.

AIM: To compare the safety and efficacy of percutaneous computed tomography (CT)-guided core-needle biopsy (CNB) of pancreatic masses traversing the gastrointestinal tract or solid viscera versus trans-mesenteric and retroperitoneal approaches. MATERIALS AND METHODS: CT-guided CNB of pancreatic lesions performed between May 2004 and December 2014 were retrospectively analysed at a single centre. Biopsies were performed using 18- or 20-G needles with a coaxial system. CT images, histopathology reports, medical records, and procedural details for all patients were reviewed to evaluate the biopsy route, complications, and diagnostic accuracy. According to the routes, biopsies were divided into trans-mesenteric, retroperitoneal and trans-organ approaches for comparison. RESULTS: A total of 85 patients, who had undergone 89 CNBs for pancreatic masses were reviewed. The overall sensitivity, specificity, and accuracy of CNB for detecting malignancy via various routes were 88.8%, 100%, and 89.9%, respectively, with a complication rate of 20.2%. Trans-organ biopsies of pancreatic masses (n=22) were performed safely via a direct pathway traversing the stomach (n=14), colon (n=3), small bowel (n=2), liver (n=2), and spleen (n=1). The sensitivity, specificity, and accuracy were 90.5%, 100%, and 90.9%, respectively. In the trans-organ biopsy group, three biopsies (13.6%) resulted in minor haematomas, but no major complications occurred. There were no statistically significant differences in the diagnostic efficacy or complication rate among the different biopsy routes. CONCLUSION: Percutaneous CT-guided CNB using a trans-organ approach is a feasible technique for diagnosing pancreatic malignancy; however, as this series was small, more data is required.

iSlide: a 'big picture' interactive teledermatopathology e-learning system.

BACKGROUND: Dermatopathology training is often limited by facilities and a dearth of specialists. Advancements in information and communication technologies have made possible the adoption of innovative learning techniques, especially in places where specialists are lacking. OBJECTIVES: To implement and evaluate the performance of the iSlide system, which is an interactive dermatopathology training platform (http://scope.tmu.edu.tw/islide2/). METHODS: Fifty-two cases representing a variety of dermatopathology conditions and complications were used to set up the iSlide system, and virtual slides of these cases were produced. Medical students from the Dermatology Department of Taipei Medical University were taught to use the system. Performance of the system was evaluated and validated using questionnaires, the first comprising 20 questions and the second a shorter, six-question telephone-based survey on 15 of the 96 interns. Twenty cases prepared by the iSlide system were also presented at an international dermatopathology conference and evaluated by conference participants. RESULTS: Ninety-six students and 72 experts participated in the study. Ninety-two per cent of the students and 98% of the experts found the iSlide system to be a useful tool for learning dermatopathology. Of these, 82% of the students and 63% of the experts felt that iSlide was easy to use. CONCLUSIONS: iSlide is useful for dermatopathology. As only 82% of the student evaluators and 63% of the expert evaluators found the system easy to use, further work has to be done to improve the iSlide interface to make the system more user friendly.

Long-term efficacy and safety of ustekinumab, with and without dosing adjustment, in patients with moderate-to-severe psoriasis: results from the PHOENIX 2 study through 5 years of follow-up.

BACKGROUND: Evaluation of the dosing flexibility and long-term efficacy of biological agents is limited. OBJECTIVES: To evaluate the long-term efficacy and safety of ustekinumab with and without dosing adjustment in the 5-year PHOENIX 2 study. METHODS: Patients were randomized to placebo or ustekinumab (45 or 90 mg) at weeks 0, 4, then every 12 weeks; patients receiving placebo crossed-over at week 12. Dosing adjustments were permitted at/beyond week 28 for early adjusters (weeks 28 or 40 per response); late adjusters (during long-term extension per investigator judgement); and nonadjusters (maintained randomized treatment throughout the study). Efficacy and safety were evaluated through weeks 244 and 264, respectively. RESULTS: In the overall population, 70% (849 of 1212) of ustekinumab-treated patients completed treatment through week 244, with high proportions of patients responding to the 45-mg and 90-mg doses, respectively: 75% improvement in Psoriasis Area and Severity Index (PASI 75) (76·5% and 78·6%) and PASI 90 (50·0% and 55·5%). Approximately 20% of patients were early adjusters, 30% were late adjusters and 50% were nonadjusters. Approximately half of the late adjusters initiated adjustments after already achieving PASI 75. Improved response was generally observed following dosing adjustments. Through week 264, safety event rates did not increase and event rates were generally comparable between dose groups and between patients with and without dosing adjustment. CONCLUSIONS: Treatment with ustekinumab for up to 5 years was safe and effective. Improved response was generally demonstrated following dosing adjustments; further investigations are required to quantify actual incremental benefits. The results also suggest that some patients may desire treatment goals beyond PASI 75.

A higher anti-Müllerian hormone level is associated with an increased chance of pregnancy in patients undergoing controlled ovarian stimulation and intrauterine insemination.

Anti-Müllerian hormone (AMH) level has been found to be a useful marker of ovarian reserve, and a predictor of poor and hyper-responses in patients undergoing controlled ovarian stimulation (COS). The study aimed to determine the association of serum AMH level with achieving pregnancy in patients undergoing COS with intrauterine insemination. The cross-sectional study investigated 204 patients who underwent COS with intrauterine insemination at the Obstetrics and Gynecology Department of Taipei Medical University Hospital, from January 2011 to March 2012. The medical records of these patients were reviewed, and serum AMH levels were evaluated for association with successful clinical pregnancy. The AMH level in the patients who achieved clinical pregnancy was significantly higher than in patients who did not (median 2.7 vs 2.0 ng/ml, p = 0.005). Controlling for factors affecting infertility, AMH level had a significant independent influence on outcome; a higher AMH level was associated with a decreased risk of a non-pregnant outcome (odds ratio, OR = 0.895, p = 0.026). In patients undergoing COS and intrauterine insemination, a low AMH level is associated with a decreased chance of a clinical pregnancy, and this association remains irrespective of the presence or absence of endometriosis.

Impact of physician specialty on classification of physician-perceived patient severity for patients with osteoarthritis.

BACKGROUND: Physicians often classify patients' osteoarthritis (OA) severity subjectively. As treatment decisions are influenced by severity classifications, it is important to understand the factors that influence physicians' OA severity ratings. This research sought to empirically identify physician and patient characteristics that lead to a patient being perceived as having more severe OA. METHODS: Data were analyzed from the OA IX Disease Specific Program, a large cross-sectional survey of OA physicians and patients in Germany, the UK, and USA between September 2011 and January 2012. Eligible, consenting physicians completed a Patient Record Form (PRF) for 10 consecutive OA patients. The PRF asked physicians to report the patient's demographics [age, gender, body mass index (BMI), ethnicity], their assessment of the patients' symptom severity, treatment, probability for surgery, to rate their overall OA severity (mild, moderate or severe) and the factors that had influenced the rating. Chi-squared tests and analysis of variance were used to identify patient characteristics that significantly impacted physicians' OA severity ratings. Controlling for the significant patient characteristics, we then examined the impact of physician specialty on physician's OA severity ratings. Finally, we investigated the differences in physician-reported factors that influenced the physicians' rating of patients' severity between physician specialties. RESULTS: Three hundred and sixty-three physicians [220 primary care physicians (PCPs), 48 rheumatologists, 95 orthopedic surgeons] recruited 3561 patients. Patients with greater age and BMI, worse symptoms and greater health care use were given higher OA severity ratings. Controlling for these factors, orthopedic surgeons rated their OA patients as more severe than PCPs and rheumatologists [adjusted odds ratio (OR) 1.8, 95% confidence interval (CI) 1.4-2.4]. Specialists (rheumatologists and orthopedic surgeons) were more likely than PCPs to use joint spaced narrowing based on X-ray and severity of joint deterioration radiographic severity to assess patients' OA severity (joint space narrowing: 79% and 78% vs 55%, P < 0.0001). CONCLUSIONS: Patient age, BMI, presence and severity of symptoms and health care use significantly impacted physicians' OA severity ratings, but radiographic changes appeared to be given greater weight among orthopedic surgeons and rheumatologists than PCPs when assessing patient severity. Whether these differences translate into different treatment recommendations for similar patients is unknown, and warrants study.

Risk of colorectal cancer in women with pelvic inflammatory disease: a matched cohort study.

OBJECTIVE: Inflammation is an important risk factor for the development of colorectal cancer (CRC). Pelvic inflammatory disease (PID) comprises a spectrum of upper genital tract infections and inflammatory diseases. We aimed to evaluate the association between CRC and PID. DESIGN: Matched cohort study using the National Health Insurance Research Database. SETTING: Women with PID in Taiwan. POPULATION AND SAMPLE: From the Longitudinal Health Insurance Database 2005 (LHID2005) in Taiwan, we obtained data on women from 13 to 45 years of age who were diagnosed with PID. The women with PID were matched 1:4 to selected members of the population without PID based on age and year of first entry into the LHID2005. METHODS: A Cox proportional hazards model was used to evaluate the hazard ratio for CRC during the 5-year follow-up period, after adjusting for sociodemographic characteristics and selected comorbid medical disorders. MAIN OUTCOME MEASURES: Colorectal cancer. RESULTS: Of the 19,029 women with PID, 30 were diagnosed with CRC during the 78,965 person-year follow-up period. Of the 76,116 control women, 66 were diagnosed with CRC. The CRC hazard ratio during the 5-year follow-up period was 2.00 (95% CI 1.30-3.08) for women with PID relative to control women. Similarly, after adjusting for age, Charlson comorbidity index score, urbanisation level and monthly income, the adjusted CRC hazard ratio was 1.71 (95% CI 1.10-2.65) for the women with PID relative to the women in the comparison cohort. CONCLUSIONS: Here we show a weak association between PID and CRC. Additional studies are needed to further evaluate this association and examine plausible mechanisms, including the influence of specific microorganisms.

Trans-organ versus trans-mesenteric computed tomography-guided percutaneous fine-needle aspiration biopsy of pancreatic masses: feasibility and safety.

AIM: To evaluate the safety and efficacy of computed tomography (CT)-guided percutaneous fine-needle aspiration biopsy (FNAB) of pancreatic masses that traverses the gastrointestinal tract or solid viscera. MATERIALS AND METHODS: From January 2002 to December 2012, 144 patients underwent 165 CT-guided biopsies of pancreatic masses. Biopsies were performed using a 21 or 22 G needle. Cytology reports, medical records, and procedure details for all patients were retrospectively reviewed to evaluate the biopsy route, complications, and diagnostic accuracy. RESULTS: Trans-organ biopsies of pancreatic masses were safely performed via a direct pathway traversing the stomach (n = 45), colon (n = 14), jejunum (n = 4), or liver (n = 5). There were five self-limiting mesenteric haematomas along the biopsy route on immediate post-procedure CT and all patients remained asymptomatic. All haematomas occurred after a trans-mesenteric approach rather than passage through abdominal organs. Three patients had acute pancreatitis. There was no significant difference in complications and diagnostic yields between the groups. The sensitivity, specificity, positive predictive value, and negative predictive value of final FNAB cytology for malignancy were 98.3%, 100%, 100% and 71.4%, respectively. The overall accuracy was 98.4%. CONCLUSION: Percutaneous FNAB using the trans-organ approach is a safe and effective technique to diagnose pancreatic malignancy.

Long-term safety of ustekinumab in patients with moderate-to-severe psoriasis: final results from 5 years of follow-up.

BACKGROUND: Long-term safety evaluations of biologics are needed to inform patient management decisions. OBJECTIVES: To evaluate the safety of ustekinumab in patients with moderate-to-severe psoriasis treated for up to 5 years. METHODS: Safety data were pooled from four studies of ustekinumab for psoriasis. Rates of adverse events (AEs), serious AEs (SAEs) and AEs of interest [infections, nonmelanoma skin cancers (NMSCs), other malignancies and major adverse cardiovascular events (MACE)] per 100 patient-years (PY) of follow-up were analysed by ustekinumab dose (45 or 90 mg) and by year of follow-up (years 1-5) to evaluate the dose response and impact of cumulative exposure. Observed rates of overall mortality and other malignancies were compared with those expected in the general U.S. population. RESULTS: Analyses included 3117 patients (8998 PY) who received one or more doses of ustekinumab, with 1482 patients treated for ≥4 years (including 838 patients ≥5 years). At year 5, event rates (45 mg, 90 mg, respectively) for overall AEs (242·6, 225·3), SAEs (7·0, 7·2), serious infections (0·98, 1·19), NMSCs (0·64, 0·44), other malignancies (0·59, 0·61) and MACE (0·56, 0·36) were comparable between dose groups. Year-to-year variability was observed, but no increasing trend was evident. Rates of overall mortality and other malignancies were comparable with those expected in the general U.S. population. CONCLUSIONS: No dose-related or cumulative toxicity was observed with increasing duration of ustekinumab exposure for up to 5 years. Rates of AEs reported in ustekinumab psoriasis trials are generally comparable with those reported for other biologics approved for the treatment of moderate-to-severe psoriasis.

Histology and outcomes of newly detected lung lesions in melanoma patients.

BACKGROUND: Melanoma frequently metastasizes to the lung. Improved radiologic techniques may decrease the need for biopsy of such lesions. The aim of this study was to examine factors predictive of a positive biopsy of melanoma. METHODS: Using the Memorial Sloan-Kettering Cancer Center melanoma database, all patients with melanoma who had undergone biopsy of a suspicious new lung lesion from 1996 to 2009 were identified. Age, date of diagnosis, histology, and stage were obtained. Chart review was carried out to obtain medical history, smoking status, radiological appearance, and histology of lung lesions biopsied. RESULTS: Two hundred and twenty-nine patients were identified; median age was 63 years; 48% were never smokers; 27% had a prior nonmelanoma cancer; 88% of lung nodules were malignant: 69% melanoma, 19% other cancers. Among 113 patients undergoing positron emission tomography (PET), proportions of benign, melanoma, and nonmelanoma 2-[fluorine-18]fluoro-2-deoxy-D-glucose-avid nodules did not differ (P = 0.53). On multivariable analysis, >stage I melanoma, negative smoking history, multiple lung nodules, and no prior nonmelanoma cancer were significantly associated with a melanoma biopsy result rather than other cancer. CONCLUSIONS: In this study, 31% of lung lesions were not melanoma. In the subset undergoing PET, this did not differentiate between benign and malignant lesions. Biopsy is mandated in melanoma patients with new lung nodules.
