Hidradenitis suppurativa (HS) is a chronic, inflammatory, recurrent disease, usually presenting after puberty with inflammatory lesions that mainly affect the apocrine gland-bearing areas of the body, most commonly the axillary, inguinal and anogenital regions. The treatment of HS is associated with certain challenges due to intrinsic resistance to various treatments and the presence of comorbidities and complications. The antibiotic dapsone is an established treatment for HS, but the current evidence base is limited. The aim of this review is to systematically review the literature on the efficacy of dapsone in the treatment of HS.

The Cochrane, PubMed and CINAHL databases were searched for relevant articles to be included in the systematic review.

A total of seven studies, with a cumulative patient population of 135 patients, were included. Of these 135 patients, 62.2% demonstrated various degrees of improvement following treatment. However, as only three of the seven studies used dapsone monotherapy it is difficult to assess the effectiveness of dapsone because the benefits observed may be due to concurrently administered treatment.

Overall, the quality of evidence supporting the use of dapsone is weak. However, it is a well established treatment recommended in current, various national guidelines. There is a crucial need for well-designed randomized controlled trials to support its usage.

Following the 2009 H1N1 pandemic, focus has been directed on the burden of influenza globally. Country and regional disease burden estimates play important roles in helping inform decisions on national influenza intervention programmes. Despite improvements in influenza surveillance following the 2009 pandemic, many opportunities remain unexplored in the Eastern Mediterranean and North African (EMNA) region, which has a high prevalence of patients with chronic disease and thus a population at high risk of influenza complications. We conducted a systematic literature review of Embase, Medline, Scopus and the Cochrane Database of Systematic Reviews from 1 January 1998 to 31 January 2020 covering the EMNA region with the aim to describe the epidemiology of influenza in the region and assess the influenza epidemiological surveillance research landscape.

Advances in rheumatoid arthritis (RA) management have made disease remission achievable. We evaluated trends in total hip replacement (THR) and postoperative outcomes in patients with RA in Western Australia (WA) over more than three decades.

This was a retrospective analysis of routinely collected prospective data from a state-wide registry containing longitudinally linked administrative health data based on International Classification of Diseases (ICD) diagnostic and procedural codes. We included patients with two or more diagnostic codes for RA (between 1980 and 2015) and studied THR incidence rates (THR IR) and complication rates (revision, peri-prosthetic fracture, infection, venous thrombosis, and mechanical loosening). Survival rates were estimated by Kaplan-Meier method and predictors analyzed by Cox regression.

We followed 9201 RA patients over 111,625 person-years, during which 1560 patients (16.9%) underwent THR. From 1985 to 2015, THR IR (per 1000 RA patient-years) decreased from 20.8 (95% CI 20.1-21.5) to 7.3 (95% CI 7.2-7.5), and 5-year THR-free survival increased from 84.3 to 95.3% (1980-2015). Ten-year prosthetic survival was 91.2%. Complication rates in the first 5years post-THR decreased significantly from 13.1 to 3.7% (p < 0.001). Mechanical complications such as loosening and periprosthetic fracture rates decreased significantly (> 35%, P < 0.05), while infection and revision did not change over the observation period (p > 0.05).

Over the last 30years in RA patients, THR IR and mechanical complication rates decreased significantly, but the medical complication of infection has not changed significantly.

Pegloticase, a PEGylated uricase for uncontrolled gout, rapidly lowers serum urate (SU). Selleckchem Zeocin Not all patients complete a full-therapy course because anti-pegloticase antibodies can develop, causing efficacy loss and infusion reactions. The literature and clinical trial data indicate that methotrexate co-administration markedly improves pegloticase response rates from the established monotherapy response rate of 42%. Unfortunately, methotrexate use is restricted by kidney disease, which is often present in uncontrolled gout patients. Leflunomide is less restricted in patients with renal dysfunction. This study examined the treatment response rate of pegloticase co-administered with leflunomide.

Patients co-treated with pegloticase (8mg biweekly infusion) and oral leflunomide (20mg/day) were included. Patient/treatment characteristics and safety parameters (adverse events [AEs], laboratory parameters) were examined. Pre-infusion prophylaxis was administered (day of infusion IV solumedrol, night before and morniapy to pegloticase in uncontrolled gout patients. Heterogeneity and high comorbidity burden in uncontrolled gout patients makes having a variety of immunomodulators options important.

This study supports leflunomide as co-therapy to pegloticase in uncontrolled gout patients. Heterogeneity and high comorbidity burden in uncontrolled gout patients makes having a variety of immunomodulators options important.

We examined prescription medication use and identified correlates of polypharmacy-taking multiple medications-in adolescent and young adult cancer survivors (AYAs), who experience early-onset chronic conditions.

Our cross-sectional study pooled data (2008-2017) from the national Medical Expenditure Panel Survey. We estimated prevalence of polypharmacy (≥ 5 unique prescription medications over an approximate 1-year period) in AYAs (age 18-39years with a history of cancer) and age- and sex-matched controls, overall and by sociodemographics, clinical factors, and health indicators. We compared survivors' and controls' medication use across therapeutic classes. To identify correlates of polypharmacy among AYAs, we included factors with p < 0.20 in bivariable analysis in a multivariable logistic regression model.

AYAs (n = 601) had a higher prevalence of polypharmacy than controls (n = 2,402), overall (31.5% vs. 15.9%, p < .01) and by all sociodemographics, clinical factors, and health indicators. A majority of AYAs with multiple chronic conditions (58.8%, 95% CI 47.3-70.4) or disability (61.3%, 95% CI 52.6-70.0) had polypharmacy. Patterns of AYAs' medication use across therapeutic classes were consistent with their chronic conditions. Nearly one-third used opioid/narcotic analgesics (32.2% vs. 13.7% of controls, p < 0.01). Among AYAs, multiple chronic conditions (aOR 4.68, 95% CI 2.23-9.83) and disability (aOR 3.70, 95% CI 2.23-6.14) were correlated with polypharmacy.

Chronic conditions and disabilities, including aftereffects of cancer treatment, may drive polypharmacy in AYAs. Future research should examine adverse outcomes of polypharmacy and opioid/narcotic use in AYAs.

AYAs with chronic conditions or disabilities should be monitored for polypharmacy.

RAPN is a minimally invasive surgery, and the spreading of RAPN in partial nephrectomy (PN) performed annually is expected to reduce the number of blood transfusions in Japan. The number of PN surgery in Japan was calculated using the Japanese NDB open data in 2018. We extracted articles comparing the transfusion rates of RAPN and OPN from 2017 to 2021 using PubMed, Web of Science, and Ichu-shi, and integrated the ratios of transfusion rates by meta-analysis. We estimated the reduction in the annual transfusion cases in PN due to the widespread use of RAPN. The total number of renal cancer surgeries in 2018 was 21,298, of which 3,876 (18.2%) were RAPN and 4,384 (20.6%) were OPN. For the comparison of transfusion implementation rate between RAPN and OPN, 871 articles were screened and 27 articles were included. The pooled ratio in transfusion rate of RAPN compared with OPN was 0.49 [0.46, 0.52]; the introduction of RAPN was estimated to have reduced the annual number of transfusions in PN by 9.1% compared with that of unintroduced RAPN. This study showed quantitatively evaluated the impact of the introduction of RAPN on the decrease in the annual number of transfusions in Japan. This method has the potential to evaluate the impact of robot-assisted surgery on the use of blood products for transfusion.

Dealing with variants of unknown significance (VUS) is an important issue inthe clinical application of NGS-based cancer gene panel tests. We detected a novel ERBB2 extracellular domain VUS, c.1157A > G p.(E401G), in a cancer gene panel test. Since the mechanisms of activation by ERBB2 extracellular domain (ECD) variants are not fully understood, we aimed to clarify those mechanisms and the biological functions of ERBB2 E401G.

ERBB2 E401G was selected as VUS for analysis because multiple software tools predicted its pathogenicity. We prepared ERBB2 expression vectors with the E401G variant as well as vectors with S310F and E321G, which are known to be activating mutations. On the basis of wild-type ERBB2 or mutant ERBB2 expression in cell lines without ERBB2 amplification or variants, we evaluated the phosphorylation of human epidermal growth factor receptor 2 and related proteins, and investigated with molecular dynamics (MD) simulation the mechanisms conferred by the variants. The biological effects of ERBB2 E401G were also investigated, both in vitro and in vivo.

We found that ERBB2 E401G enhances C-terminal phosphorylation in a way similar to S310F. MD simulation analysis revealed that these variants maintain the stability of the EGFR-HER2 heterodimer in a ligand-independent manner. Moreover, ERBB2 E401G-transduced cells showed an increased invasive capacity in vitro and an increased tumor growth capacity in vivo.

Our results provide important information on the activating mechanisms of ERBB2 extracellular domain (ECD) variants and illustrate a model workflow integrating wet and dry bench processes for the analysis of VUS detected with cancer gene panel tests.
