The objective of this article is to describe surgical techniques for the management of localized penile cancer concurrent with adult acquired buried penis. Penile cancer, while rare, invariably impacts quality of life as the primary surgical management ranges from local excision to total penectomy. Penile cancer has recently been linked to adult acquired buried penis (AABP) with the hypothesis that chronic inflammation of the penis contributes to risk of penile malignancy. Buried penis reconstruction is now a well-described procedure involving escutcheonectomy and split thickness skin grafting which has been shown to improve quality of life in individuals with adult acquired buried penis.This report describes a patient with AABP requiring partial penectomy and inguinal node dissection who also underwent adult acquired buried penis repair during his procedure. A review of cases of buried penis cases was carried out and four other cases of penile cancer were identified who were managed with penile preserving procedures.This combination of surgical techniques strives to improve quality of life and facilitate cancer surveillance without compromising oncologic outcomes.

We found that the systematic use of Delphi consensus diagnostic criteria resulted in substantial changes in management patterns in cases of suspected pyoderma gangrenosum (PG), including a reduction in systemic corticosteroid use, and significantly improved clinical outcomes. This improvement may have resulted from a combination of reduced misdiagnosis, optimized management and reduced iatrogenic harm. Increased utilization of validated diagnostic criteria for PG could optimize provider heuristics, increase diagnostic accuracy, and optimize management and clinical outcomes.

Background: The European post-authorisation study (EU PAS) register is a repository launched in 2010 by the European Medicines Agency (EMA). All EMA-requested PAS, commonly observational studies, must be recorded in this register. Multi-database studies (MDS) leveraging secondary data have become an important strategy to conduct PAS in recent years, as reflected by the type of studies registered in the EU PAS register. Objectives: To analyse and describe PAS in the EU PAS register, with focus on MDS. Methods: Studies in the EU PAS register from inception to 31st December 2018 were described concerning transparency, regulatory obligations, scope, study type (e.g., observational study, clinical trial, survey, systematic review/meta-analysis), study design, type of data collection and target population. MDS were defined as studies conducted through secondary use of >1 data source not linked at patient-level. Data extraction was carried out independently by 14 centres with expertise in pharmacoepidemiology, using publicly available information in the EU PAS register including study protocol, whenever available, using a standardised data collection form. For validation purposes, a second revision of key fields for a 15% random sample of studies was carried out by a different centre. The inter-rater reliability (IRR) was then calculated. Finally, to identify predictors of primary data collection-based studies/versus those based on secondary use of healthcare databases) or MDS (vs. non-MDS), odds ratios (OR) and 95% confidence intervals (CI) were calculated fitting univariate logistic regression models. Results: Overall, 1426 studies were identified. Clinical trials (N = 30; 2%), systematic reviews/meta-analyses (N = 16; 1%) and miscellaneous study designs (N = 46; 3%) were much less common than observational studies (N = 1227; 86%). The protocol was available for 63% (N = 360) of 572 observational studies requested by a competent authority. Overall, 36% (N = 446) of observational studies were based fully or partially on primary data collection. Of 757 observational studies based on secondary use of data alone, 282 (37%) were MDS. Drug utilisation was significantly more common as a study scope in MDS compared to non-MDS studies. The overall percentage agreement among collaborating centres that collected the data concerning study variables was highest for study type (93.5%) and lowest for type of secondary data (67.8%). Conclusions: Observational studies were the most common type of studies in the EU PAS register, but 30% used primary data, which is more resource-intensive. Almost half of observational studies using secondary data were MDS. Data recording in the EU PAS register may be improved further, including more widespread availability of study protocols to improve transparency.

Since 2014, valproate has not been recommended for use in girls and women of childbearing potential unless other treatments are ineffective or not tolerated. Risk minimization measures (RMMs) of valproate were implemented to reduce the potential risks of developmental disorders among pregnant women. A drug utilization study was carried out to assess the effectiveness of RMMs.This was a multinational, non-interventional cohort study. For the UK, existing data from the Clinical Practice Research Datalink database were used. The primary study endpoint was a change in the proportion of valproate initiations preceded by other medications relevant for valproate indications before and after implementation of RMMs.The proportion of valproate initiations preceded by medications related to valproate indications increased after RMM implementation in incident female users in the UK from 66.4% to 72.4%. The proportion of incident prescriptions for epilepsy and bipolar disorder with prior medication related to valproate indications increased, from 36.2% to 44.1% and 72.9% to 77.8%, respectively. The incidence rate of valproate-exposed pregnancies decreased from 16.9 to 10.9 per 1000 person-years in the pre- and post-implementation periods, respectively.Results from this study indicated some improvement in physician prescribing and a potential reduction in valproate-exposed pregnancies in the UK. Given only modest improvement has been achieved, additional RMMs were implemented in 2018.

Background Supportive care is the cornerstone of management of adult and paediatric Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). However, consensus on the modalities of supportive care is lacking.Objectives Our aim in this international multicentric Delphi exercise was to establish a multidisciplinary expert consensus to standardize recommendations regarding supportive care in the acute phase of SJS/TEN.Methods Participants were sent a survey via the online tool SurveyMonkey, consisting of 103 statements organized into 11 topics: multidisciplinary team composition, suspect drug management, infection prevention, fluid resuscitation and prevention of hypothermia, nutritional support, pain and psychological distress management, management of acute respiratory failure, local skincare, ophthalmological management, management of other mucosa, and additional measures. Participants evaluated the level of appropriateness of each statement on a scale of 1 (extremely inappropriate) to 9 (extremely appropriate). The results were analysed according to the RAND/UCLA Appropriateness Method.Results Forty-five participants from 13 countries (on three continents) participated. After the first round, a consensus was obtained for 82.5% of the 103 initially proposed statements. After the second round, a final consensus was obtained for 102 statements.Conclusions We have reached an international Delphi-based consensus on best supportive care practice for SJS/TEN. Our expert consensus should help guide physicians in treating patients with SJS/TEN and thereby improve short-term prognosis and the risk of sequelae.

Refereed/Peer-reviewed Objectives: Ambiguity in communication of key study parameters limits the utility of real-world evidence (RWE) studies in healthcare decision-making. Clear communication about data provenance, design, analysis, and implementation is needed. This would facilitate reproducibility, replication in independent data, and assessment of potential sources of bias. Methods: The International Society for Pharmacoepidemiology (ISPE) and ISPOR–The Professional Society for Health Economics and Outcomes Research (ISPOR) convened a joint task force, including representation from key international stakeholders, to create a harmonized protocol template for RWE studies that evaluate a treatment effect and are intended to inform decision-making. The template builds on existing efforts to improve transparency and incorporates recent insights regarding the level of detail needed to enable RWE study reproducibility. The over-arching principle was to reach for sufficient clarity regarding data, design, analysis, and implementation to achieve 3 main goals. One, to help investigators thoroughly consider, then document their choices and rationale for key study parameters that define the causal question (e.g., target estimand), two, to facilitate decision-making by enabling reviewers to readily assess potential for biases related to these choices, and three, to facilitate reproducibility. Strategies to Disseminate and Facilitate Use: Recognizing that the impact of this harmonized template relies on uptake, we have outlined a plan to introduce and pilot the template with key international stakeholders over the next 2 years. Conclusion: The HARmonized Protocol Template to Enhance Reproducibility (HARPER) helps to create a shared understanding of intended scientific decisions through a common text, tabular and visual structure. The template provides a set of core recommendations for clear and reproducible RWE study protocols and is intended to be used as a backbone throughout the research process from developing a valid study protocol, to registration, through implementation and reporting on those implementation decisions.

Background Alopecia areata (AA) is an immune-mediated disease resulting in nonscarring hair loss. Systematic reviews on the psychosocial and psychiatric comorbidities, health-related quality of life, and interventions targeting psychosocial well-being are limited. Objective To conduct a systematic review of the psychosocial comorbidities, health-related quality of life, and treatment options targeting psychosocial well-being in adult and pediatric AA patients. Methods A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines within the PubMed database. Specific search terms included, but were not limited to, alopecia areata, psychosocial, psychiatry, and quality of life. Studies were then evaluated for their design and categorized into corresponding levels of evidence according to the guidelines adapted from the Oxford Center for Evidence Based Medicine. Findings Seventy-three reports met inclusion criteria, involving approximately 414,319 unique participants. AA patients were found to have psychiatric comorbidities, particularly anxiety and depression. Health-related quality of life is reduced in AA patients, but data on pediatric AA quality of life are limited. Psychotherapy is often recommended as adjuvant treatment. Conclusion AA has substantial psychosocial impact on patients and results in reduced health-related quality of life. Addressing this should be an active part of treatment.

Summary Background & aims Malnutrition is prevalent in upper gastrointestinal cancer patients. The purpose of this study was a comprehensive assessment of nutritional status in newly diagnosed patients with esophageal cancer. Methods Newly diagnosed esophageal cancer patients were referred to a chemo-radiation referral center in Mashhad, Iran, between February 2017 to February 2019. Anthropometric indices, a Patient-Generated Subjective Global Assessment (PG-SGA) tool, body composition, dietary intake, nutritional-related complications, and laboratory tests were assessed. Results One hundred and eighty-nine patients with a mean age of 67.1 ± 12 and a male to female ratio of 98 to 91 were included. Ninety-seven (51.3%) of patients had experienced significant weight loss and 56 (29.6%) were underweight at diagnosis. According to PG-SGA, 179 (94.7%) needed nutritional interventions. Reduced muscle mass and low handgrip strength were observed in 70 (39.4%) and 26 (14.4%) of patients, respectively. Inadequate intakes of energy (less than 24 kcal/kg/day) and protein (less than 1.2 g/kg/day) were found in 146 (77.8%) and 171 (91%) patients, respectively. The mean total daily energy and protein intakes of subjects were 943.8 ± 540 kcal/day, and 30.6 ± 21 g/day, respectively. The most common nutritional-related complications were as follows: dysphagia (84.8%), anorexia (31.6%), constipation (62.1%), esophageal pain (48.4%), and dyspepsia (41.1%). Conclusion Our study demonstrated a high prevalence of malnutrition in newly diagnosed esophageal cancer patients. This fact demonstrates the importance of early screening of nutritional status via PG-SGA tool, clinical evaluation, dietary intake evaluations, and laboratory tests, based on which effective nutritional interventions and Symptoms management may be introduced in these patients.

The epidermis is the outermost layer of skin. Here, we used targeted lipid profiling to characterize the biogeographic alterations of human epidermal lipids across 12 anatomically distinct body sites, and we used single-cell RNA-Seq to compare keratinocyte gene expression at acral and nonacral sites. We demonstrate that acral skin has low expression of EOS acyl-ceramides and the genes involved in their synthesis, as well as low expression of genes involved in filaggrin and keratin citrullination (PADI1 and PADI3) and corneodesmosome degradation, changes that are consistent with increased corneocyte retention. Several overarching principles governing epidermal lipid expression were also noted. For example, there was a strong negative correlation between the expression of 18-carbon and 22-carbon sphingoid base ceramides. Disease-specific alterations in epidermal lipid gene expression and their corresponding alterations to the epidermal lipidome were characterized. Lipid biomarkers with diagnostic utility for inflammatory and precancerous conditions were identified, and a 2-analyte diagnostic model of psoriasis was constructed using a step-forward algorithm. Finally, gene coexpression analysis revealed a strong connection between lipid and immune gene expression. This work highlights (a) mechanisms by which the epidermis is uniquely adapted for the specific environmental insults encountered at different body surfaces and (b) how inflammation-associated alterations in gene expression affect the epidermal lipidome.

Proprotein convertase subtilisin/kexin type-9 (PCSK9) is a posttranslational regulator of the LDL receptor (LDLR). Recent studies have proposed a role for PCSK9 in regulating immune responses. Using RNA-Seq-based variant discovery, we identified a possible psoriasis-susceptibility locus at 1p32.3, located within PCSK9 (rs662145 C > T). This finding was verified in independently acquired genomic and RNA-Seq data sets. Single-cell RNA-Seq (scRNA-Seq) identified keratinocytes as the primary source of PCSK9 in human skin. PCSK9 expression, however, was not uniform across keratinocyte subpopulations. scRNA-Seq and IHC demonstrated an epidermal gradient of PCSK9, with expression being highest in basal and early spinous layer keratinocytes and lowest in granular layer keratinocytes. IL36G expression followed the opposite pattern, with expression highest in granular layer keratinocytes. PCSK9 siRNA knockdown experiments confirmed this inverse relationship between PCSK9 and IL36G expression. Other immune genes were also linked to PCSK9 expression, including IL27RA, IL1RL1, ISG20, and STX3. In both cultured keratinocytes and nonlesional human skin, homozygosity for PCSK9 SNP rs662145 C > T was associated with lower PCSK9 expression and higher IL36G expression, when compared with heterozygous skin or cell lines. Together, these results support PCSK9 as a psoriasis-susceptibility locus and establish a putative link between PCSK9 and inflammatory cytokine expression.

Lupus miliaris disseminatus faciei (LMDF) is a chronic inflammatory dermatosis of unknown aetiology, most often seen in young adults. Although many treatments for LMDF exist, treatment guidelines have not been developed, and response to therapy is generally unpredictable. We present the results of transcriptomic analysis of LMDF lesional skin, which revealed a variety of differentially expressed genes linking LMDF to alterations in innate and adaptive T helper 1 immunity. Immunohistochemical analysis was also performed, identifying similar changes in T-cell immune responses. Given evidence for increased tumour necrosis factor (TNF) pathway activity, our patient, who had previously been refractory to multiple treatments, was initiated on TNF inhibitor therapy with excellent response. This characterization of the LMDF immune response may lead to improved treatment of this condition.

Daratumumab, a monoclonal antibody targeting CD38, is approved to treat multiple myeloma. Red blood cells express low levels of CD38, which can result in a false-positive antibody screen in daratumumab-treated patients. Educational materials were developed to inform healthcare professionals (HCPs) and blood transfusion management department personnel (BTMDP) about this risk and recommended measures to mitigate that risk. Materials were distributed in European countries where daratumumab was commercially available. This post-authorization safety study was designed to evaluate whether HCPs and BTMDP understood the materials. An anonymous, cross-sectional, non-interventional, web-based survey was distributed in 12 European countries. Four key questions were identified, for which a correct answer from at least 80% of respondents was considered indicative of satisfactory effectiveness. A total of 408 participants completed the questionnaires (62.3% (n = 254) HCPs and 37.7% (n = 154) BTMDP). Responses were consistent between groups. All respondents were aware of the educational materials (the first key question) and at least 80% correctly answered three of the four key questions. A key question regarding which blood typing test(s) daratumumab interferes with did not achieve satisfactory effectiveness (60% correct responses). In a weighted analysis, 79% of respondents correctly identified the recommended measures for daratumumab-treated patients requiring transfusion. This was attributed to an error in the survey’s German translation; in a sensitivity analysis, 90% of participants correctly responded to this question. Results suggest that participants were aware of the educational materials, the risk of daratumumab interference with blood testing, and recommended measures to mitigate that risk.

Nirmatrelvir coadministered with ritonavir is highly efficacious in reducing the risk of coronavirus disease 2019 (COVID-19) adverse outcomes among patients at increased risk of progression to severe disease, including patients with chronic kidney disease. Because nirmatrelvir is eliminated by the kidneys when given with ritonavir, this phase I study evaluated the effects of renal impairment on pharmacokinetics, safety, and tolerability of nirmatrelvir/ritonavir. Participants with normal renal function (n = 10) or mild, moderate, or severe renal impairment (n = 8 each) were administered a single 100-mg nirmatrelvir dose with 100 mg ritonavir given 12 hours before, together with and 12 and 24 hours after the nirmatrelvir dose. Systemic nirmatrelvir exposure increased with increasing renal impairment, with mild, moderate, and severe renal impairment groups having respective adjusted geometric mean ratio areas under the plasma concentration-time profile from time 0 extrapolated to infinite time of 124%, 187%, and 304% vs. the normal renal function group. Corresponding ratios for maximum plasma concentration were 130%, 138%, and 148%. Apparent clearance was positively correlated with estimated glomerular filtration rate, and geometric mean renal clearance values were particularly lower for the moderate (47% decrease) and severe (80% decrease) renal impairment groups vs. the normal renal function group. Nirmatrelvir/ritonavir exhibited an acceptable safety profile; treatment-related adverse events were mild in severity, and there were no significant findings regarding laboratory measurements, vital signs, or electrocardiogram assessments. These findings led to a dose reduction recommendation for nirmatrelvir/ritonavir in patients with moderate renal impairment (150/100 mg nirmatrelvir/ritonavir instead of 300/100 mg twice daily for 5 days). NCT04909853.

Typically human absorption, distribution, metabolism, and excretion (ADME) studies are executed using radiolabeled (e.g., carbon-14) material, the synthesis of which is a time-consuming activity. In this study, we were able to assess the metabolism and excretion of unlabeled nirmatrelvir (PF-07321332) within the first-in-human study via a novel application of quantitative fluorine (

Purpose The purpose of this study was to evaluate the effectiveness of the risk minimisation measures (RMMs) implemented in Europe in 2014 for valproate‐containing products to mitigate their risk during pregnancy and to characterise valproate prescribing patterns in women of childbearing potential (WCBP) before and after implementation of RMMs. Methods A multinational cohort study based on existing data sources using a pre‐/post‐ design was performed in five European countries (France, Germany, Spain, Sweden, UK) in an outpatient setting. Effectiveness of RMMs was assessed by comparing the proportion of valproate initiations as second (or subsequent) line therapy before and after implementation of RMMs (primary outcome) with an increase in this proportion indicating success of RMMs. Overall use of valproate and incidence of pregnancies in WCBP were also examined. Results The proportion of valproate initiations as second line therapy increased after implementation of RMMs in incident female users in Sweden (from 81.1%, 95% CI 79.9%‐82.3% to 84.5%, 95% CI 83.5%‐85.5%) and the UK (from 66.4%, 95% CI 64.5%‐68.3% to 72.4%, 95% CI 70.0%‐74.9%), it remained the same in Germany and Spain and decreased in France from 48.7% (95% CI 45.6%‐51.9%) to 40.6% (95% CI 37.6%‐43.7%). In Sweden and the UK, the incidence of pregnancies exposed to valproate decreased in the post‐implementation period: 8.0 vs 9.5 and 10.9 vs 16.9 per 1000 person‐years, respectively. Conclusion The results on primary outcome of this study suggest limited effectiveness of the RMMs. Additional RMMs were implemented in 2018.

Purpose This study evaluated the effectiveness of risk minimisation measures (RMMs) implemented following the 2014 referral for valproate in Europe. Methods Cross‐sectional survey was conducted over 2‐month period in 2016 among physicians who prescribed valproate in France, Germany, the United Kingdom, Spain and Sweden. The web‐based questionnaire included five endpoints to evaluate physicians' knowledge on (a) prescribing valproate only for epilepsy and bipolar disorder in women if other treatments were ineffective or not tolerated; (b) ensuring supervision by experienced physicians while treating these conditions; (c) considering alternative treatments for women planning pregnancy, regular review of treatment needs and re‐assessing the benefit–risk balance in women and girls reaching puberty; (d) informing patients about the risks of taking valproate during pregnancy and (e) advising women on effective contraception during their treatment. Results Among 1153 physicians, 95.5% responded prescribing valproate for epilepsy and bipolar disorder in women only if other treatments are ineffective/not tolerated; 66.5% supervised while treatment; 76.6% considered alternative treatments for women planning pregnancy; 92.1% informed patients about the risks of taking valproate during pregnancy and 94.4% advised patients on the use of effective contraception during its treatment. Overall, 25.8% physicians recalled receiving both educational material (EM) and Dear Healthcare Professional Communication (DHPC). All endpoint rates were higher for physicians who acknowledged receipt of both DHPC and EM compared to physicians who did not receive them. Conclusions Although results varied across geography and physician speciality, majority of physicians had good knowledge about the indication and safety aspects of prescribing and using valproate.

Background: Malnutrition is prevalent in esophageal cancer patients which affects cancer prognosis. The purpose of this study was a comprehensive assessment of nutritional status during Chemoradiation (CRT). Methods: Newly diagnosed adults with esophageal cancer were recruited for this study. Patient-Generated- Subjective Global Assessment (PG-SGA), anthropometric indices, body composition, dietary intake, laboratory tests, and nutritional-related complications were assessed before, after, and 4 to 6 weeks after CRT. Results: Seventy-one cases were enrolled. The mean age was 66.8±12 years. Patients’ mean weight loss was 2.42±2.4 kilograms during treatment. A significant reduction observed in mean MUAC (26.68±4.9 vs. 25.42±5.1 cm), fat mass percentage (24.11±11.8 vs. 22.8±12.5), fat free mass index (16.87±2.4 vs. 16.47±2.6 kg/m2) and hand grip strength (43.2±19 vs. 36.1±20 kg) during CRT (all p-values

Nearly 15% of melanomas occur in patients with a family history and a subset of these patients have a germline mutation in a melanoma predisposing gene. CDKN2A mutations are responsible for the majority of hereditary melanoma, but many other susceptibility genes have been discovered in recent years, including CDK4, TERT, ACD, TERF2IP, POT1, MITF, MC1R, and BAP1. Additionally, melanoma risk is increased in mixed cancer syndromes caused by mutations in PTEN, BRCA2, BRCA1, RB1, and TP53. While early onset, multiple tumors, and family cancer history remain the most valuable clinical clues for hereditary melanoma, characteristic epithelioid cytology of melanocytic tumors may suggest an underlying BAP1 mutation. Herein, we review the clinical and histopathologic characteristics of melanocytic tumors associated with these germline mutations and discuss the role of genetic counseling.

Background Single-port robotic surgery is being adopted for various surgical procedures. There have been interest in and clinical use of single-port robot-assisted radical prostatectomy (spRARP), but little reported data on feasibility and early outcomes. Objective To describe our institution's initial experience with spRARP utilizing the da Vinci single-port (SP) robotic system. Design, setting, and participants A retrospective review of the initial experience of three high-volume robotic prostate surgeons performing an spRARP utilizing the da Vinci SP robotic system was carried out. Surgical procedure An spRARP using the da Vinci SP robotic system was performed following the traditional retropubic or Retzius-sparing approach. Measurements Patient demographics, operative time, blood loss, postoperative hospital stay, complications, and catheter duration were obtained and analyzed. Results and limitations In a cohort of 49 patients undergoing spRARP, median age was 62yr and prostate-specific antigen 6.4. Of the patients, 35 (71%) had cT1c disease on presentation, 92% had Gleason grade group ≥2 disease, and 85% were pT2 on final pathology. Median operative time was 161min. Median blood loss was 200ml. Seven Retzius-sparing cases were performed. Four Clavien 2 complications occurred (complication rate 8.1%). Median hospital stay was 1d and median catheter duration 7d. Operative time was Conclusions The da Vinci SP system spRARP is safe and feasible, with acceptable operative time and blood loss. Further research is needed to establish noninferiority to the da Vinci Xi and Si systems, and impact of spRARP on patient-assessed cosmesis and pain. Patient summary Robotic prostatectomy using a purpose-built da Vinci single-port robotic system is safe and feasible, and warrants further study to determine whether it can improve patient outcomes.

Studies on targeted antivirals for treatment of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the cause of the ongoing pandemic, are limited. PF-07304814 (lufotrelvir) is the phosphate prodrug of PF-00835231, a protease inhibitor targeting the 3C-like protease of SARS-CoV-2. This phase 1 study evaluated the safety, tolerability, and pharmacokinetics (PK) of single ascending intravenous doses of lufotrelvir (continuous 24-hour infusion of 50, 150, 500, or 700 mg) versus placebo in healthy volunteers (2 interleaving cohorts: 1, n = 8; 2, n = 7). Each dosing period was separated by a washout interval (≥5 days). Treatment-emergent adverse events, PK, and biomarker concentrations were estimated from plasma/urine samples. Lufotrelvir was administered to 15 volunteers (mean [SD] age 39.7 [11.8] years). No serious adverse events, discontinuations, or deaths were reported. Mean maximum observed concentration of PF-00835231 (active moiety; 97.0 ng/mL to 1288 ng/mL) were observed between median time to maximum concentration of 14 to 16 hours after the start of the lufotrelvir infusion. Near-maximum plasma concentrations of PF-00835231 were observed ≈6 hours after infusion start and sustained until infusion end. PF-00835231 plasma concentrations declined rapidly after infusion end (mean terminal half-life: 500 mg, 2.0 hours; 700 mg, 1.7 hours). Approximately 9%-11% of the dose was recovered in urine as PF-00835231 across doses. A continuous, single-dose, 24-hour infusion of lufotrelvir (50-700 mg) was rapidly converted to PF-00835231 (active moiety), with dose-proportional PK exposures and no significant safety concerns. A daily, 24-hour continuous infusion of 270 to 350 mg is expected to maintain PF-00835231 concentration at steady state/above effective antiviral concentrations. Further studies exploring lufotrelvir efficacy in patients with coronavirus disease 2019 are ongoing.

We evaluated the effectiveness of additional risk minimisation measures (aRMMs; i.e., educational materials) distributed to prescribers to ensure that only individuals with evidence of prior dengue infection (PDI, i.e., dengue seropositive) would be vaccinated with the tetravalent dengue vaccine (CYD-TDV; Dengvaxia®).A survey was conducted in 2020 among 300 CYD-TDV prescribers in Brazil and Thailand to ascertain three success criteria: prescribers' awareness of the materials (receiving and reading them); knowledge of the key messages; and whether their self-reported behaviour regarding practice-related scenarios was aligned with the updated guidance.The aRMMs were not generally effective as80% of prescribers in both countries met two of the three predefined success criteria. In Brazil, 98.7% were aware of the aRMMs whereas in Thailand this criterion was fulfilled by 74.0%. Almost all prescribers knew that CYD-TDV was recommended only in individuals with PDI (98.7% and 96.7% in Brazil and Thailand, respectively). In Brazil, where vaccination was restricted to those with a documented history of PDI, 11.3% considered that confirmation should be done through a blood test. More than 75% in both countries considered additional signs of dengue, as early warning signs, and not only those regarded as such by the 2009 WHO guidelines.These results do not support that the aRMMs were effective as the predefined success criteria were not met. The use of reliable rapid diagnosis tests together with the revised prescribing information and educational materials will facilitate the implementation and compliance with pre-vaccination screening for CYD-TDV eligibility.

The current guidelines for malaria prevention and control during pregnancy in Africa is predicated on the prevention of infection and/or disease through intermittent preventive treatment in pregnancy (IPTp), insecticide-treated nets (ITNs) and effective malaria case diagnosis and management. Concerns that increasing SP resistance in some areas of SSA may have compromised IPTp-SP efficacy prompted this contemporaneous study, designed to assess the prevalence and risk factors of sub-microscopic infection in parturient women during the low transmission season in Mutengene, a rapidly growing semi-urban area in Southwest Region, Cameroon. Pregnant women originally reporting for the establishment of antenatal clinic care during the dry season were followed-up to term and their pregnancy outcomes recorded. About 2 ml of venous blood was collected for malaria diagnosis using PfHRP2/pLDH malaria rapid diagnostic kit and light microscopy. DNA was extracted from dried blood spots by the Chelex-100 method and the Plasmodium falciparum status detected by nested PCR amplification of the 18SrRNA gene using specific predesigned primers. Of the 300 women enrolled, the proportion of malaria parasite infected as determined by microscopy, RDT and PCR was 12.9%, 16.4% and 29.4% respectively, with 39.9% overall infected with P. falciparum by microscopy and/or RDT and/or PCR and a very low-density infection, averaging 271 parasites per microliter of blood. About 25.0% (68/272) of women who were negative by microscopy were positive by PCR (submicroscopic P. falciparum infection), with primigravidae and IPTp-SP non usage identified as independent risk factors for submicroscopic P. falciparum parasitaemia while fever history (aOR = 4.83, 95% CI = 1.28–18.22, p = 0.020) was associated with risk of malaria parasite infection overall. IPTp-SP use (p = 0.007) and dosage (p = 0.005) significantly influenced whether or not the participant will be malaria parasite negative or carry submicroscopic or microscopic infection. Although Infant birthweight and APGAR score were independent of the mother’s P. falciparum infection and submicroscopic status, infant’s birthweight varied with the gravidity status (p = 0.001) of the mother, with significantly lower birthweight neonates born to primigravidae compared to secundigravidae (p = 0.001) and multigravidae (p = 0.003). Even in holo-endemic dry season, there exists a large proportion of pregnant women with very low density parasitaemia. IPTp-SP seems to be relevant in controlling submicroscopic P. falciparum infections, which remains common in pregnant women, and are hard to diagnose, with potentially deleterious consequences for maternal and fetal health. Future studies should be carried out in hyperendemic malaria foci where the parasitemia levels are substantially higher in order to confirm the efficacy of IPTp-SP.

Risk minimisation measures for valproate were implemented in Spain in 2015.The objective of this study is to assess the effectiveness of valproate risk minimisation measures in Spain intended to decrease the use of valproate as a first-line therapy, and to evaluate the prescribing patterns of valproate in women, including women of childbearing potential, in the pre- and post-implementation risk minimisation measures periods.The prescribing patterns of valproate in females and women of childbearing potential before and after risk minimisation measures implementation were examined using the longitudinal patient data database, which includes patient information from two panels: primary care physicians and neurologists/psychiatrists. Primary endpoint was the proportion of initial valproate prescriptions with at least one medication related to the valproate indications before the valproate initiation date.The proportion of incident valproate prescriptions with previous use of medication related to valproate indications was 78.0% (95% CI, 73.9%; 81.5%), and 78.2% (74.5%; 81.4%) in the main pre-and post-implementation periods in the primary care physician panel. The corresponding figures for women of childbearing potential were 79.6% (73.6%; 84.5%) and 75.5% (69.7%; 80.6%), respectively. The incidence rate of pregnancies exposed to valproate (per 1,000 person-years) in women of childbearing potential decreased from 17.4 the entire pre-implementation to 8.5 in the entire post-implementation periods.After the implementation of risk minimisation measures for valproate in Spain, no meaningful change in prescribing was observed regarding the proportion of valproate initiations preceded by prior medication related to valproate indications. The preventative measures recommended for use of valproate in women of childbearing potential should be considered.Eficacia de las medidas de minimización de riesgos del ácido valproico: estudio de utilización del fármaco en Europa, análisis de datos de España.Introducción. En 2015 se aplicaron en España distintas medidas para la minimización de los riesgos (MMR) del ácido valproico. Objetivo. El objetivo de este estudio es evaluar la eficacia de las MMR del ácido valproico en España, con el fin de reducir el uso de ácido valproico como terapia de primera línea y evaluar los patrones de prescripción de ácido valproico en las mujeres, incluidas las mujeres en edad fértil (MEF), en los períodos previos y posteriores a la implementación de las MMR. Materiales y métodos. Los patrones de prescripción del ácido valproico en mujeres y MEF antes y después de la implementación de las MMR se examinaron utilizando la base de datos longitudinales de pacientes (longitudinal patient data, LPD por sus siglas en inglés), que incluye información de pacientes de dos paneles: médicos de atención primaria (MAP) y neurólogos/psiquiatras. El criterio principal de valoración fue la proporción de prescripciones iniciales de ácido valproico con al menos un medicamento relacionado con indicaciones de ácido valproico antes de la fecha de inicio del ácido valproico. Resultados. La proporción de prescripciones de ácido valproico secundarias con uso previo de medicamentos relacionados con indicaciones de ácido valproico fue del 78% –intervalo de confianza (IC) al 95%: 73,9-81,5%– y del 78,2% (IC al 95%: 74,5-81,4%) en los períodos principales previo y posterior a la implementación en el panel de MAP. Las cifras correspondientes a MEF fueron del 79,6% (IC al 95%: 73,6-84,5%) y del 75,5% (IC al 95%: 69,7-80,6%), respectivamente. La tasa de incidencia de embarazos expuestos al ácido valproico (por 1.000 personas-años) en MEF disminuyó de 17,4 en el período completo previo a la implementación a 8,5 en el período completo posterior a la implementación. Conclusión. Tras la implementación de las MMR del ácido valproico en España no se observó ningún cambio significativo en las prescripciones respecto a la proporción de iniciaciones de ácido valproico precedidas por medicación previa relacionada con indicaciones de ácido valproico. Se deben tener en cuenta las medidas preventivas recomendadas para el uso de ácido valproico en MEF.

Porphyria cutanea tarda (PCT) is a phototoxic cutaneous disease linked to elevated liver iron levels and photosensitizing heme precursors. Here, we report a 65-year-old man with a history of hypertension and heavy alcohol and tobacco use who presented to clinic for evaluation of an intensely pruritic rash on his arms present for 6 years. A biopsy completed 3 years prior demonstrated a lichenoid drug eruption.

Aims Two post-authorisation studies assessed the safety and persistence of patients’ use of nalmefene. Methods The START study (EUPAS5678) was a non-interventional, multi-country, prospective, 18-month (8 follow-up visits) cohort study including outpatients initiating nalmefene for the first time. The multi-database retrospective cohort study (MDRC, EUPAS14083) included baseline and follow-up data from German, Swedish and UK healthcare databases. Both studies permitted ‘all comers’ without explicit exclusion criteria; predefined subgroups of interest included the elderly (≥65 years) as well as patients with significant psychiatric and/or somatic comorbidities. Results START study: Overall, the mean duration of nalmefene treatment was 10.3 ± 7.3 months (N = 1348), with 49.0% of patients treated for ≥1 year; frequent reasons for treatment discontinuation were ‘goal reached’ and ‘drug cost’. The most frequently reported adverse drug reactions (ADRs) were nausea (4.7%), dizziness (3.2%) and insomnia (2.0%). ADR rates appeared higher in the elderly subpopulation (18.6% reported ≥1 ADR vs. 12.0% in the total population) but were not higher in the other predefined subgroups. MDRC study: The database follow-up analysis followed 2892 patients over 18 months for whom the duration of nalmefene treatment was between 2 and 3 months and, Short Summary: Two studies were used to evaluate the safety and persistence of nalmefene in the routine management of alcohol dependence in Europe as part of the overall risk management plan. Although adverse events appeared more common in over 65-year olds, there were no major differences in safety outcomes between the total population, and those with psychiatric and somatic comorbidities or those with a history of seizures. Findings were in line with those from previous clinical studies. The differing rates of persistence beyond 1 year (49% in the prospective study and

Background/objective Patients with juvenile idiopathic arthritis (JIA) often present with signs and symptoms suggestive of serious bacterial infection (SBI). Procalcitonin (PCT) is a biomarker that is elevated in SBI. We conducted a comparative cohort study to test the hypothesis that PCT levels will differ between active JIA, quiescent JIA, and bacteremic patients and healthy controls. Methods From October 2016 to May2018, consecutive children 6 months to 18 years of age with (a) active untreated JIA, (b) quiescent JIA, and (c) healthy elective presurgical candidates were recruited from clinics at a musculoskeletal specialty hospital. Juvenile idiopathic arthritis was defined according to the International League of Associations for Rheumatology criteria. Clinical data and serum samples meeting the same criteria were included from a prior study. Consecutive bacteremic patients were identified over the same period. Procalcitonin and other common measures of inflammation were measured. Descriptive statistics and univariate logistic analyses were performed. Results Ninety-two study subjects were recruited. Erythrocyte sedimentation rate, C-reactive protein (CRP), and PCT levels were all elevated in bacteremic patients in comparison to the other groups. Erythrocyte sedimentation rate and CRP both had wide ranges that overlapped between groups; however, the PCT concentration was 0.15 μg/mL or greater in 1 of 59 patients with JIA, whereas it was 0.15 μg/mL or less in only 1 bacteremic patient. Conclusions Our study indicates that serum erythrocyte sedimentation rate, CRP, and PCT levels are all biomarkers that can be used to distinguish SBI versus active JIA at presentation. However, PCT is the most accurate, with the least overlap between patients with infection and noninfectious inflammatory arthritis. This finding can help clinicians direct therapy.

Introduction Hypersensitivity reactions (HSRs) are among the known adverse events of intravenous (i.v.) iron products. Of these, particularly severe HSRs such as anaphylaxis are of great clinical concern due to their life-threatening potential. Methods This was a retrospective pharmacoepidemiological study with a case-population design evaluating the number of reported severe HSRs following administration of the two i.v. iron products—ferric carboxymaltose and iron (III) isomaltoside 1000—in relation to exposure in European countries from January 2014 to December 2017. Exposure to both products was estimated using IQVIA MIDAS sales data in European countries. Information on spontaneously reported severe HSRs was obtained from and analysed separately for the two established safety surveillance databases EudraVigilance and VigiBase™ using the MedDRA® Preferred Terms anaphylactic reaction, anaphylactic shock, anaphylactoid reaction and anaphylactoid shock associated with administration of either product. Results Between 2014 and 2017, the reporting rate of severe HSRs per 100,000 defined daily doses (100 mg dose equivalents of iron) varied from 0.3 to 0.5 for ferric carboxymaltose and from 2.4 to 5.0 for iron (III) isomaltoside 1000. The reporting rate ratio for iron (III) isomaltoside 1000 versus ferric carboxymaltose was between 5.6 (95% CI 3.5–9.0) and 16.2 (95% CI 9.4–27.8). Conclusions Findings suggest that iron (III) isomaltoside 1000 is associated with a higher reporting rate of severe HSRs related to estimated exposure than ferric carboxymaltose in European countries. Future research investigating the occurrence of severe HSRs associated with i.v. ferric carboxymaltose and iron (III) isomaltoside 1000 is needed to broaden the evidence for benefit-risk assessment.

Diagnostic ureteroscopic biopsy for upper tract urothelial carcinoma (UTUC) has been hypothesized to increase intravesical recurrence of urothelial carcinoma after radical nephroureterectomy (RNU). Moreover, the impact of ureteroscopy without biopsy or percutaneous biopsy on intravesical recurrence remains unknown. Herein, we compared post-RNU intravesical recurrences across UTUC diagnostic modalities.Patients undergoing RNU at our institution between 1995 and 2019 were categorized by UTUC diagnostic modality: 1) no ureteroscopy or percutaneous biopsy; 2) percutaneous biopsy; 3) ureteroscopy without biopsy; 4) ureteroscopic biopsy. Intravesical recurrences were compared using Kaplan-Meier analyses and Cox-proportional hazard models. Results of group 4 vs 1 were pooled with the literature using a fixed effects meta-analysis.In a cohort of 834 RNU patients, 210 (25.2%) had undergone no ureteroscopy, 57 (6.6%) percutaneous biopsy, 125 (15.0%) ureteroscopy without biopsy, and 442 (53.0%) ureteroscopic biopsy. Two-year intravesical recurrence rates were 15.0%, 12.7%, 18.4%, and 21.9% for groups 1 through 4, respectively (p=0.09). Multivariable analysis found that group 4 had increased intravesical recurrences (HR 1.40, p=0.04) relative to group 1 while group 2 (HR 1.07, p=0.87) and group 3 (HR 1.15, p=0.54) did not. Group 4 remained associated with intravesical recurrence on subset analyses accounting for post-RNU surveillance cystoscopy frequency. On meta-analysis including 11 other series, ureteroscopic biopsy was associated with intravesical recurrence (HR 1.47, p0.01).Ureteroscopic biopsy before RNU, but not percutaneous biopsy or ureteroscopy without biopsy, was associated with increased intravesical recurrence. Clinical trials of intravesical chemotherapy after ureteroscopic biopsy are warranted to reduce intravesical recurrences.

This study aimed to narratively summarize the literature reporting on the effect of teamwork and communication training interventions on culture and patient safety in emergency department (ED) settings.We searched PubMed, EMBASE, Psych Info CINAHL, Cochrane, Science Citation Inc, the Web of Science, and Educational Resources Information Centre for peer-reviewed journal articles published from January 1, 1988, to June 8, 2018, that assessed teamwork and communication interventions focusing on how they influence patient safety in the ED. One additional search update was performed in July 2019.Sixteen studies were included from 8700 screened publications. The studies' design, interventions, and evaluation methods varied widely. The most impactful ED training interventions were End-of-Course Critique, Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS), and crisis resource management (CRM)-based training. Crisis resource management and TeamSTEPPS CRM-based training curriculum were used in most of the studies. Multiple tools, including the Kirkpatrick evaluation model, the Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture, the TeamSTEPPS Teamwork Attitudes Questionnaire, the Safety Attitudes Questionnaire, and the Communication and Teamwork Skills Assessment, were used to assess the impact of such interventions. Improvements in one of the domains of safety culture and related domains were found in all studies. Four empirical studies established improvements in patient health outcomes that occurred after simulation CRM training (Kirkpatrick 4), but there was no effect on mortality.Overall, teamwork and communication training interventions improve the safety culture in ED settings and may positively affect patient outcome. The implementation of safety culture programs may be considered to reduce incidence of medical errors and adverse events.

Iatrogenic vascular occlusion secondary to filler injection, such as with hyaluronic acid, is a known but rare, entity. It typically occurs in the setting of facial cosmetic procedures but has also been described in the setting of osteoarthritis. We present a patient with ankle osteoarthritis who developed an asymmetric, reticular, livedoid eruption after intraarticular injection with hyaluronic acid. She was diagnosed with livedo racemosa secondary to vascular occlusion and placed on low molecular weight heparin. Later, a transition to low-dose daily aspirin maintained the improvement.

IMPORTANCE: Palmoplantar pustulosis (PPP) is a is a chronic, orphan disease with limited epidemiological data. OBJECTIVE: To describe the clinical characteristics, treatments, longitudinal disease course, and health care utilization in adults with PPP across the US. DESIGN, SETTING, AND PARTICIPANTS: This retrospective, longitudinal case series from 20 academic dermatology practices in the US included a consecutive sample of 197 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for PPP between January 1, 2007, and December 31, 2018. Data analysis was performed June 2020 to December 2020. MAIN OUTCOMES AND MEASURES: The primary outcome was to describe the patient characteristics, associated medical comorbidities, treatment patterns, complications, and PPP-specific health care utilization. RESULTS: Of 197 patients, 145 (73.6%) were female, and the mean (SD) age at presentation was 53.0 (12.6) years, with a mean (SD) follow-up time of 22.1 (28.0) months. On initial presentation, 95 (48.2%) patients reported skin pain, and 39 (19.8%) reported difficulty using hands and/or feet. Seventy patients (35.5%) were treated with systemic treatments, and use of more than 20 different systemic therapies was reported. In patients with at least 6 months of follow-up (n = 128), a median (IQR) of 3.7 (4-10) dermatology visits per year were reported; 24 (18.8%) patients had 5 or more visits during the study period. CONCLUSIONS AND RELEVANCE: In this case series, PPP was associated with persistent symptoms, continued health care utilization, and a lack of consensus regarding effective treatments, emphasizing the unmet medical need in this population. Additional research is necessary to understand treatment response in these patients.

IMPORTANCE: Generalized pustular psoriasis (GPP) is a chronic, orphan disease with limited epidemiological data. OBJECTIVE: To describe the clinical characteristics, treatments, longitudinal disease course, and disease-specific health care utilization among patients with GPP across the United States. DESIGN, SETTING, AND PARTICIPANTS: A retrospective longitudinal case series involving 95 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for GPP and were treated at 20 US academic dermatology practices between January 1, 2007, and December 31, 2018. MAIN OUTCOMES AND MEASURES: The primary outcome is to describe the patient characteristics, associated medical comorbidities, treatment patterns complications, and GPP–specific health care utilization. RESULTS: Sixty-seven of 95 patients (70.5%) were women (mean age, 50.3 years [SD, 16.1 years]). In the initial encounter, 35 patients (36.8%) were hospitalized and 64 (67.4%) were treated with systemic therapies. In total, more than 20 different systemic therapies were tried. During the follow-up period, 19 patients (35.8%) reported hospitalizations at a median rate of 0.5 hospitalizations per year (IQR, 0.4-1.6). Women had a decreased risk of an emergency department or hospital encounter (odds ratio, 0.19; 95% CI, 0.04-0.83). CONCLUSIONS AND RELEVANCE: Generalized pustular psoriasis is a rare, chronic disease without standard treatment and is associated with continued health care utilization over time.

Recent reports show a correlation between renal tumor radiographic characteristics and pathologic features. We hypothesize that a more central location within the relatively hypoxic renal medulla might confer a more aggressive tumor phenotype. To test this, radiographic tumor characteristics were compared with tumor grade and histology.We retrospectively reviewed renal masses 4 cm in diameter that underwent resection between 2008 and 2013. Tumor location was recorded using standard R.E.N.A.L. Nephrometry Score. Multivariate logistic regression was performed to compare independent anatomic features with incidence of malignancy and high nuclear grade.A total of 334 renal tumors had information available for analysis. Univariate analysis showed that increasing endophycity and proximity to the collecting system (4 mm) were predictors of malignancy and high-grade features. In multivariate analysis, proximity to the collecting system 4 mm remained the as the only anatomical variable predictive of malignancy (odds ratio [OR], 3.58; 95% confidence interval [CI], 1.06-12.05; P = .04) and high nuclear grade (OR, 2.81; 95% CI, 1.44-5.51; P = .003).Malignancy and high tumor grade occur with much greater frequency when tumors are located deep in the kidney, in close proximity to the collecting system and renal sinus. Ninety-six percent of small renal masses in this region were cancers and nearly half were Fuhrman Grade 3 or 4, suggesting that these small centrally located tumors should be targeted for early intervention.

OBJECTIVE To better understand the safety and diagnostic yield of percutaneous core-needle biopsy (PCNB) for upper tract urothelial carcinoma (UTUC). METHODS Of 444 patients undergoing radical nephroureterectomy (RNU) for UTUC between 2009 and 2017 at our institution, 42 who had PCNB prior to RNU were identified for analysis. Endpoints included safety, diagnostic yield, and concordance with RNU pathology. PCNB specimens were deemed histologically concordant with RNU specimens for cases when cytologic evaluation of biopsy specimen and corresponding pathologic evaluation of RNU specimen both made a histologic diagnosis of urothelial carcinoma. RESULTS Median tumor size was 3.8 cm (1.2-10.2 cm). All lesions arose from the pelvicalyceal system. CT-guidance was utilized in 52% (n = 22), and ultrasound-guidance in 48% (n = 20). Relative to RNU pathology, 95% of PCNBs demonstrated histologic concordance. Histologic grade was provided in 69% (n = 29) of PCNBs, with a 90% (n = 26) concordance with surgical pathology. Grades 1-2 and 3 complications occurred in 14.3% (n = 6) and 2.4% (n = 1), respectively. At a median follow-up of 28.2 months (range, 1.2-97.1 months) after biopsy, no cases of radiographic tract seeding were identified. CONCLUSION In our cohort of 42 patients undergoing RNU for UTUC, PCNB appeared a safe diagnostic tool with high histologic yield and grade concordance. With greater than 2 years of follow-up, no cases of tract seeding were identified.

Background Previous studies of penile traction therapy (PTT) devices have demonstrated limited/no efficacy when combined with intralesional therapies for Peyronie’s disease (PD). Recently, randomized data have demonstrated the efficacy of a novel PTT device, RestoreX, developed in cooperation with the Mayo Clinic, in men with PD. Aim To assess the safety and efficacy of treatment with the RestoreX device plus collagenase Clostridium histolyticum (CCH) compared with CCH alone and CCH with other PTT devices. Methods A prospective registry has been maintained of all men undergoing CCH injections for PD between March 2014 and January 2019. Assessments were performed at baseline, during each series, and after completion of treatment. Those completing therapy (8 injections or sooner if satisfied) were categorized into group 1 (CCH alone), group 2 (CCH plus any PTT device other than RestoreX), or group 3 (CCH plus RestoreX). Outcomes Changes in penile length, curvature, and subjective perception and the occurrence of adverse events. Results Of 287 men with data on PTT use, 113 had completed therapy with all objective data available and compose the current cohort. Baseline demographic and pathophysiological variables were similar among the 3 groups except penile length and previous PD medications. Following treatment, group 3 demonstrated significantly greater improvements in curvature (mean, 20.3°/31% for group 1, 19.2°/30% for group 2, and 33.8°/49% for group 3), length (-0.7 cm/-4%, -0.4 cm/-2%, and +1.9 cm/+17%, respectively), and subjectively estimated curvature improvement (44%, 32%, and 63% respectively), despite shorter daily PTT use (0.9 vs 1.9 hours/day). Group 3 was more likely than the other groups to experience ≥20°, ≥20%, and ≥50% curvature improvements, ≥1 cm length gain, and ≥20% length improvement. All results were statistically significant for group 3 versus groups 1 and 2, but not between groups 1 and 2, even after controlling for baseline features and isolating a subset of ≥3 hours/day PTT use (group 2). Group 3 was 6.9 times more likely to achieve ≥20° curvature improvement, and 3.5 times more likely to achieve ≥50% curvature improvement, and 10.7 times more likely to experience ≥20% length improvement. Adverse events were similar among the 3 groups. Clinical Implications Use of the RestoreX device enhances mean curvature outcomes by 71% and increases penile length in men with PD receiving CCH therapy. Strengths & Limitations Study strengths include a prospective registry, consistent assessments, the largest single-site series with complete posttreatment outcomes reported to date, the largest PTT series reported to date, and a true-to-life clinical design. Limitations include the nonrandomized methodology and single-site setting. Conclusion The combination of RestoreX and CCH is associated with significantly greater curvature and length improvements compared with CCH alone or CCH with other PTT devices.

To evaluate clinicopathologic features associated with the risk of urinary tract infection (UTI) after radical cystectomy (RC), and determine the underlying organisms responsible for these events.We reviewed 1248 patients treated with RC for bladder cancer from 2000 to 2010 at Mayo Clinic. UTIs diagnosed within 90 days of surgery were recorded. Multivariable logistic regression analysis was performed to evaluate the association of clinicopathologic features with postoperative UTI.UTI was diagnosed in 129 (10.3%) patients within 90 days of RC. Median time to UTI was 22.5 days (interquartile range 14,42). On multivariable analysis, factors associated with a significantly increased UTI risk were diabetes (odds ratio [OR] 2.27; P .001), receipt of a perioperative blood transfusion (OR 1.58; P = .03), continent urinary diversion (OR 2.17;P .001), and development of a urine leak (OR 3.42;P .001). Culture-specific infection data were available for 88 of the patients, with a total of 113 UTIs diagnosed among this cohort. Of these, 36.8% of UTIs were polymicrobial. Drug-resistant Staphylococcus aureus and Enterococcus were isolated in 45.0% and 12.8% of infections, respectively. Fungal elements were present in 27 (23.9%) cultures, and were the sole organism in 15 (13.3%). No significant differences in microbial distribution or timing of infections were detected between patients who underwent conduit vs continent diversion.We found that diabetes, perioperative blood transfusion, continent diversion, and urine leak were associated with UTI risk following RC. Multiple organisms, drug resistance, and fungal elements were commonly identified, supporting the use of initial broad-spectrum coverage, including consideration of antifungal therapy, upon diagnosis of UTI after RC.

Background: Neomycin contact sensitization rates in North America range from 7% to 13%, whereas in Europe they average approximately 1.9%. Objectives: Given that topical neomycin products are no longer readily available in Canada, the aim of this study was to examine what influence this may have had on neomycin sensitization rates in the 3 western provinces. Methods: On the basis of an observation originally communicated by L. M. Parsons and C. Zhang of the University of Calgary, which suggested significantly reduced rates of neomycin sensitization in Calgary, Alberta, Canada, a multicenter study of patch test results from 5690 patient charts was undertaken. Data from 3 other western Canadian Universities (the University of Saskatchewan, the University of Alberta, and the University of British Colombia) were analyzed. Data were available from 2001 to 2013 for the University of Saskatchewan (except 2006), whereas the University of Alberta and the University of British Columbia had data from 2009 to 2013. Descriptive statistics, trend analysis, and risk estimates were determined using SPSS version 20. Results: Sensitization rates for neomycin have decreased in western Canada and are now similar to those of Europe. Conclusions: This trend is likely influenced by the reduced availability of over-the-counter and prescription neomycin products in Canada.

Summary The aim of this study was to evaluate prospectively cytokine levels and disease activity in juvenile idiopathic arthritis (JIA) patients treated with and without tumour necrosis factor (TNF)-α inhibitors. TNF-α inhibitor-naive JIA subjects were followed prospectively for 6 months. Cytokine levels of TNF-α, interleukin (IL)−1β, IL-6, IL-8, IL-10 and IL-17 were measured at baseline for JIA subjects and healthy controls (HCs). Cytokine levels were then measured at four time-points after initiation of TNF-α inhibition for anti-TNF-α-treated (anti-TNF) JIA subjects, and at two subsequent time-points for other JIA (non-TNF) subjects. JIA disease activity by Childhood Health Assessment Questionnaire (CHAQ) disability index/pain score and physician joint count/global assessment was recorded. Sixteen anti-TNF, 31 non-TNF and 16 HCs were analysed. Among JIA subjects, those with higher baseline disease activity (subsequent anti-TNFs) had higher baseline TNF-α, IL-6 and IL-8 than those with lower disease activity (non-TNFs) (P

Psoriatic arthritis (PsA) is a large volume of our clinical practice and its management can be challenging. Traditional DMARDs have been used over last six decades and observational studies have substantiated an effective use of many of these drugs. However, in last two decades use of anti-TNF agents has brought a new dimension in treatment of PsA and in many other autoimmune diseases. Regulatory role of the Th17 cells and its cytokines in the pathogenesis of PsA has successfully paved the foundations of anti-IL antibody based therapies in PsA. Newer therapies targeting the IL-23/IL-17 cytokines and its signaling proteins are now in development and bringing new promises for management of PsA. Herein, we provide an overview of the landscape of drug therapies, including IL-17, IL-12/23, IL-23 inhibitors, and janus kinase (JAK) inhibitors, as well as those in development, such as RORγt inhibitors, anti-NGF agents, mTOR inhibitors and T cell ion-channel blockers.

Psoriasis (PsO) and psoriatic arthritis (PsA) are chronic immune-mediated inflammatory diseases of multifactorial etiology. In addition to genetic and environmental factors, evidence supports involvement of a dysregulated human microbiome in the pathogenesis of psoriatic disease. In particular, alterations in the composition of the microbiome, termed dysbiosis, can result in downstream proinflammatory effects in the gut, skin, and joints. Both the cutaneous and intestinal microbial populations are implicated in the pathogenesis of psoriatic disease, although exact mechanisms are unclear. Herein, we review the relationship between the human microbiome and psoriatic disease. Further insight into the functions of the microbiome may allow for greater understanding of inflammatory disease processes and identification of additional therapeutic targets.
