Certolizumab pegol effectiveness, survival and safety in patients with psoriasis: A multicenter retrospective analysis in daily clinical practice by the Spanish Psoriasis Group.

BACKGROUND: Certolizumab is an Fc-free PEGylated tumor necrosis factor-alpha (TNFα) inhibitor recently approved for the treatment of moderate-to-severe plaque psoriasis, although there is limited real-world evidence on the effectiveness and safety in patients with plaque psoriasis treated with certolizumab. The objective of this article is to determine the effectiveness, drug survival, and safety, including pregnancy, childbirth, and lactation, of certolizumab in moderate-to-severe plaque psoriasis under real-world conditions. METHODS: This is a retrospective, multicenter, observational study performed in 15 hospitals in Spain. It evaluates the effectiveness and safety of certolizumab in plaque psoriasis in the clinical practice setting. RESULTS: A total of 67 patients (73% female) were evaluated with a mean baseline Psoriasis Area Severity Index (PASI) of 8.9. At Week 12, the mean PASI was 2.3 (n = 67), 1.3 (n = 57) at Week 24 and 1.3 at Week 52 (n = 34). Absolute PASI < 3 was achieved in 69, 86, and 92% of patients at Weeks 12, 24, and 52, respectively, as observed. For its part, using the under-response imputation analysis, PASI < 3 at Weeks 12, 24, and 52 were achieved by 69, 73, and 49% of the patients, respectively. A total of 35 patients (52%) had concomitant psoriatic arthritis, and, in 24 of them, Disease Activity in Psoriatic Arthritis Score (DAPSA) was recorded at baseline, with a mean value of 17.9 which decreased to 8.2 at Week 12 (n = 22) and to 3.6 at Week 24 (n = 18). Certolizumab treatment was discontinued in 14 out of 67 patients (21%), due to lack/loss of cutaneous or articular effectiveness (n = 11) or patient decision (n = 2) or adverse event in only one patient who developed active tuberculosis. A lower baseline PASI [hazard ratio (HR): 1.12 (1.02-1.23); P = 0.023] and a more significant reduction in PASI at Week 12 [HR: 1.16 (1.07-1.27); P < 0.001] and Week 52 [HR: 1.47 (1.11-1.96); P = 0.007] was shown to be significantly related with better survival for the entire follow-up period. Fourteen patients were treated during pregnancy and/or lactation without reporting adverse events in either the patient or the newborn. CONCLUSIONS: Certolizumab consistently showed high effectiveness and drug survival rates in this real-life cohort. The safety demonstrated in clinical trials during pregnancy and lactation seems to be confirmed in clinical practice.

Starch/carbon nanofibers bionanocomposites via melt mixing: Effect of dispersion and compatibility on conductivity and mechanical properties.

Biodegradable polymers with conductivity and mechanical properties are required in several applications where it is necessary to substitute conductive synthetic plastics due to the high waste produced. In this study, bionanocomposites (BNCs) have been compounded by thermoplastification of rice starch via melt mixing with carbon nanofibers (NPs) and modified NPs (NPs [M]) using plasma of acrylic acid. Spectroscopy analysis, X-ray diffraction, and morphology were studied to elucidate the effect of dispersion and compatibility on the conductivity and mechanical properties. The incorporation of NPs promoted esterification reactions with starch during the melt mixing process, giving rise to changes in its crystal structure. NPs [M] showed better dispersion and compatibility because the plasma prevents reagglomeration and generates a stronger affinity. BNCs showed significative flexibility with remarked % elongation at break from 5.64 % to 248.60 %, and thermal conductivity increased from 0.10 to 0.58 W/m K, with NPs [M] at 5 %. In contrast, the electrical conductivity remained in the same magnitude order (10-4 S/cm). The better compatibility between starch-NPs [M] hinders electronic transport but increases the propagation of phonons to promote thermal conductivity. BNCs fabricated in this study by a dry and scalable process could be of interest in some application areas (intelligent food packing, electronics, textiles, etc.).

Upadacitinib effectiveness in moderate-to-severe atopic dermatitis: A real-life multicentre and retrospective study.

This was an observational and retrospective multicentre study conducted on adolescents and adults diagnosed with moderate-to-severe atopic dermatitis (AD) and treated with upadacitinib. Disease severity was measured by Eczema Area and Severity Index (EASI), validated investigator global assessment for AD and pruritus Numerical Rating Scale (NRS) at baseline and Weeks 4, 16, 24 and 52 (when available). Twenty-one patients were included. All patients had previously received topical and systemic corticosteroids. Rapid response to upadacitinib was observed: Mean (SD) EASI score was 19.8 (6.5) at baseline, and 3.1 (4.2), 0.9 (1.4), 0.6 (0.6) and 0.6 (0.6) at the Weeks 4, 16, 24 and 52, respectively. Itch was controlled at Week 4 in all patients (mean [SD] NRS score 7.6 [1.9] baseline, 1.5 [1.3] W4). Severe infections or major adverse cardiovascular events were not reported. We highlight effectiveness and rapid response of upadacitinib in achieving itch control even in long-standing recalcitrant cases.

Genome characterization of two novel deep-sea sediment fungi, Penicillium pacificagyrus sp. nov. and Penicillium pacificasedimenti sp. nov., from South Pacific Gyre subseafloor sediments, highlights survivability.

BACKGROUND: Marine deep subsurface sediments were once thought to be devoid of eukaryotic life, but advances in molecular technology have unlocked the presence and activity of well-known closely related terrestrial and marine fungi. Commonly detected fungi in deep marine sediment environments includes Penicillium, Aspergillus, Cladosporium, Fusarium, and Schizophyllum, which could have important implications in carbon and nitrogen cycling in this isolated environment. In order to determine the diversity and unknown metabolic capabilities of fungi in deep-sea sediments, their genomes need to be fully analyzed. In this study, two Penicillium species were isolated from South Pacific Gyre sediment enrichments during Integrated Ocean Drilling Program Expedition 329. The inner gyre has very limited productivity, organic carbon, and nutrients. RESULTS: Here, we present high-quality genomes of two proposed novel Penicillium species using Illumina HiSeq and PacBio sequencing technologies. Single-copy homologues within the genomes were compared to other closely related genomes using OrthoMCL and maximum-likelihood estimation, which showed that these genomes were novel species within the genus Penicillium. We propose to name isolate SPG-F1 as Penicillium pacificasedimenti sp. nov. and SPG-F15 as Penicillium pacificagyrus sp. nov. The resulting genome sizes were 32.6 Mbp and 36.4 Mbp, respectively, and both genomes were greater than 98% complete as determined by the presence of complete single-copy orthologs. The transposable elements for each genome were 4.87% for P. pacificasedimenti and 10.68% for P. pacificagyrus. A total of 12,271 genes were predicted in the P. pacificasedimenti genome and 12,568 genes in P. pacificagyrus. Both isolates contained genes known to be involved in the degradation of recalcitrant carbon, amino acids, and lignin-derived carbon. CONCLUSIONS: Our results provide the first constructed genomes of novel Penicillium isolates from deep marine sediments, which will be useful for future studies of marine subsurface fungal diversity and function. Furthermore, these genomes shed light on the potential impact fungi in marine sediments and the subseafloor could have on global carbon and nitrogen biogeochemical cycles and how they may be persisting in the most energy-limited sedimentary biosphere.

Klotho Levels and Their Relationship with Inflammation and Survival among Alcoholic Patients.

α-Klotho (Klotho) is an antiaging hormone with anti-inflammatory and antioxidative properties. Some studies suggest that Klotho increases in response to enhanced oxidative damage and inflammation. Alcoholism is a proinflammatory condition. The aim of this study was to analyze the relationship between Klotho and the serum levels of the inflammatory markers in alcoholic liver disease and to assess its prognostic value. We included 184 alcoholics and 35 age- and sex-matched controls. We determined the serum levels of Klotho, the tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-8, and malondialdehyde (MDA), and routine laboratory variables. Patients were followed-up with during 16 ± 18 months; 67 patients died. Klotho levels were higher among cirrhotics (with KW = 37.00 and p < 0.001) and were related to the Child−Pugh score (with KW = 15.96 and p < 0.001) and to the TNF-α (ρ = 0.28; p < 0.001) and MDA (ρ = 0.21; p = 0.006). The child's groups were associated with mortality, both in the univariate (with the log-rank = 13.56, p = 0.001, Breslow = 12.33, and p = 0.002) and multivariate (with ß = 0.43, p = 0.02, and OR = 1.53 (1.07−2.15)) analyses, also introducing Klotho and the TNF-α as dichotomic variables. However, the independent prognostic value of the Child's groups was displaced by Klotho when only cirrhotics were considered; Klotho, over the median (574.4 pg/mL), was associated with higher mortality (with p = 0.04 and OR = 2.68 (1.06−6.84)). We conclude that Klotho is increased in liver cirrhosis. It is directly related to TNF-α, MDA, and to mortality in cirrhotics.

Sclerostin in Excessive Drinkers: Relationships with Liver Function and Body Composition.

BACKGROUND: Sclerostin was initially described as an inhibitor of the Wnt-ß catenin bone-forming pathway, but it also exerts important effects on intermediate metabolism and body composition. Osteosarcopenia and altered body fat distribution are common findings in excessive drinkers. The role of sclerostin in these patients is uncertain. We aim to analyze the behavior of sclerostin in excessive drinkers and its relationships with body composition (fat mass, lean mass, bone mass), handgrip strength, body mass index (BMI), liver function and ethanol intake. METHODS: 107 male active heavy drinkers and 26 age-matched controls were included. Serum sclerostin was determined by ELISA. Body composition analysis was performed by double X-ray absorptiometry. Handgrip strength was recorded using a dynamometer. Liver function was assessed according to Child's classification. RESULTS: Sclerostin was higher among Child's C patients, keeping a relationship with deranged liver function. Obesity, defined according to BMI, and body fat were strongly related to sclerostin, being independent of serum creatinine and of liver function. The relationship of sclerostin with total hip bone mineral density was displaced by BMI. CONCLUSION: Deranged liver function is associated with higher sclerostin levels in alcoholics. Raised sclerostin levels are related to fat deposition and increased BMI.

Brain-derived neurotrophic factor among patients with alcoholism.

BACKGROUND: Brain-derived neurotrophic factor (BDNF) is involved in neurogenesis and in the protection against oxidative damage and neuronal apoptosis. After exercise, there is an increased expression of this myokine, especially in skeletal muscle and brain. Low BDNF levels have been described in neurodegenerative diseases. Alcoholics show both muscle atrophy and brain atrophy. Thus, this study was performed in order to analyze serum BDNF levels among alcoholics and their associations with brain atrophy and muscle strength. METHODS: Serum BDNF values were determined to 82 male alcoholics and 27 age-matched controls, and compared with handgrip strength, with the presence of brain atrophy, assessed by computed tomography, and with the intensity of alcoholism and liver function derangement. RESULTS: BDNF levels and handgrip strength were significantly lower among patients. Handgrip strength was correlated with BDNF values, both in the whole population and in alcoholics, especially in patients over 59 years of age. BDNF was poorly related to liver dysfunction but showed no relationship with brain atrophy or age. CONCLUSION: Chronic alcoholics show decreased BDNF serum levels that are related to muscle function impairment rather than to age, brain atrophy, liver dysfunction, or the amount of ethanol consumed.

Pigmentation and Degradative Activity of TiO2 on Polyethylene Films Using Masterbatches Fabricated Using Variable-Frequency Ultrasound-Assisted Melt-Extrusion.

Ultrasound-assisted melt-extrusion method (USME) is a high-quality process used to produce polymeric compounds with an adequate homogeneous dispersion. This study evaluates white-color films of linear low-density polyethylene (LLDPE) prepared using TiO2 masterbatch obtained by ultrasound-assisted melt-extrusion at variable frequencies (USME-VF). LLDPE with three different melt-flow indices (2, 20 and 50 g/10 min) were used as the polymer matrix. The films were obtained from the dilution of masterbatches of LLDPE (melt-flow index = 2) at a concentration of 7 wt% TiO2. The morphology, pigmentation, TiO2 reactivity, and the mechanical stability of the films were assessed. The masterbatch compounds were evaluated by melt-flow index (MFI) and scanning electron microscopy (SEM). The contrast ratio, yellowness index and mechanical properties of films were also measured. The properties of whiteness and elongation at break improved in the films prepared using masterbatches with higher dispersion. Though the reactivity of the TiO2 particles increased during accelerated aging, it did not affect the elongation to rupture. The yellowness index was moderately affected in films that included TiO2 particles processed using USME-VF.

COVID-19 and Advanced Practice Registered Nurses: Frontline Update.

Coronavirus disease 2019 (COVID-19) emerged in 2019 and rapidly became a global pandemic, infecting millions and killing hundreds of thousands. The disease altered the practices of hospitals, clinics, and patients. These changes have implications for advanced practice registered nurses (APRNs). APRNs must remain current on best practices for treatment and diagnosis of COVID-19 while being cognizant of changes to their scope of practice. As the pandemic continues, APRNs will remain on the front lines treating patients with COVID-19 while also caring for vulnerable populations within the community. To provide high-quality care, APRNs must use a multifaceted approach that heeds ongoing updates to evidence-based practice.

Incidence of cancer and mortality among heavy alcoholics.

BACKGROUND AND AIMS: Cancer risk is increased in alcoholics. Heavy ethanol consumption is also associated with other potentially lethal conditions such as cirrhosis, diabetes, hypertension, dyslipidemia or malnutrition, that increase mortality. The aim of the present study is to analyze the impact on mortality of new cancer development in a cohort of heavy alcoholics. METHODS: Three hundred and thirty nine heavy alcoholics (about 200 g ethanol/daily during more than 15 years), initially admitted for organic problems to our service (reference hospital) were prospectively followed up for a maximum period of 120 months (median = 26, interquartile range = 12-60 months), either as outpatients or during successive admissions. Clinical and laboratory evaluation including incidence of new cancer and drinking habits were recorded at each appointment, as well as mortality. RESULTS: During the study period 57 patients developed cancer and 151 died. Only 75 did not relapse in alcohol drinking. Mortality was related to deranged liver function, relapse of alcohol drinking, and malnutrition, whereas age, the development of new cancer, or the presence of diabetes, dyslipidemia or hypertension did not influence on mortality, especially in cirrhotics and among those who did not quit drinking. Cancer was related to mortality only among non-cirrhotics, together with ethanol abstention and age. CONCLUSIONS: Heavy drinking is associated with high mortality among alcoholic patients admitted to the hospital. If a patient is already cirrhotic or if there is drinking relapse, the development of a new cancer, the concurrent presence of diabetes, hypertension, dyslipidemia, or advanced age have no impact on survival. Mortality is only related to deranged liver function, relapse of alcohol drinking, and malnutrition.

Background matching, disruptive coloration, and differential use of microhabitats in two neotropical grasshoppers with sexual dichromatism.

Cryptic coloration is an adaptative defensive mechanism against predators. Color patterns can become cryptic through background coloration-matching and disruptive coloration. Disruptive coloration may evolve in visually heterogeneous microhabitats, whereas background matching could be favored in chromatically homogeneous microhabitats. In this work, we used digital photography to explore the potential use of disruptive coloration and background matching in males and females of two grasshopper species of the Sphenarium genus in different habitats. We found chromatic differences in the two grasshopper species that may be explained by local adaptation. We also found that the females and males of both species are dichromatic and seem to follow different color cryptic strategies, males are more disruptive than females, whereas females have a high background matching with less disruptive elements. The selective pressures of the predators in different microhabitats and the differences in mobility between sexes may explain the color pattern divergence between females and males. Nevertheless, more field experiments are needed in order to understand the relative importance of disruptive and background matching coloration in the evolution of sexual dichromatism in these grasshoppers.

Prognostic Value of Serum Iron, Ferritin, and Transferrin in Chronic Alcoholic Liver Disease.

Ethanol increases iron absorption. Therefore, increased amount of iron reaches the liver, and exerts pro-oxidant effects and stimulates ferritin synthesis and hepatic stellate cell activation, promoting fibrosis and inflammation. These mechanisms would theoretically support a role of ferritin as a marker of the transition to liver cirrhosis, and, consequently, as a prognostic factor, but there is controversy regarding its behavior in alcoholics. We analyzed among 238 severe alcoholics the prognostic value of iron, ferritin, transferrin, transferrin saturation index (TSI) and total iron binding capacity (TIBC), and the relationships of these variables with liver function, proinflammatory markers (C-reactive protein (CRP), interleukin (IL)-6, IL-8, and tumor necrosis factor α), and the presence of cirrhosis. Patients showed higher serum ferritin (Z = 2.50, p = 0.031) but lower transferrin (t(264) = 4.81, p < 0.001), TIBC (t(262) = 4.44, p < 0.001), and iron (Z = 3.19, p = 0.001) values compared with 32 age- and sex-matched controls. Ferritin was related to inflammatory cytokines such as IL-8 (ρ = 0.18, p = 0.012) and to IL-6 (ρ = 0.16, p = 0.016), but not to liver function. On the contrary, cirrhotics showed lower transferrin (t(234) = 4.77, p < 0.001) and TIBC (t(232) = 4.67, p < 0.001), but higher TSI (Z = 3.35, p < 0.001) than non-cirrhotics. Transferrin, TSI, and TIBC were related to liver function impairment (marked differences among the Child's groups regarding transferrin (KW (2) = 22.83, p < 0.001), TSI (KW (2) = 15.81, p < 0.001), and TIBC (KW (2) = 21.38, p < 0.001) but only weakly to inflammation (inverse relationships between IL-6 and total iron (ρ = - 0.16, p = 0.017), TIBC (ρ = - 0.20, p = 0.002), and transferrin (ρ = - 0.20, p = 0.003). In accordance, albumin, IL-6, alcohol quitting, and TSI, in this order, were independently related to mortality, but not ferritin or iron.

[Cutaneous metastasis of prostate adenocarcinoma: a case report]. / Metástasis cutánea de adenocarcinoma de próstata: reporte de un caso.

Cutaneous metastases are very rare events and are related to a distant tumor invasion. Prostate metastases have a 1% appearance rate; the most common locations include the genital or suprapubic region and are very rarely located at a distance. We report the case of a male patient with cutaneous metastasis of prostate adenocarcinoma located in the cervical and upper thoracic area. The patient also had a history of pulmonary tuberculosis. A CT scan revealed the presence of bone metastasis, pleural effusion, and infiltration of the soft tissues of the neck. The histopathological study confirmed the presence of cutaneous metastasis of primary prostate neoplasia. We present this case due to its unusualness and its importance in the differential diagnosis of this pathology.

A comparison of the growth performance, carcass traits, and behavior of guinea pigs reared in wire cages and floor pens for meat production.

To achieve efficient production of guinea pigs for meat, it is essential to determine the most suitable housing system. A total of 220 guinea pigs were maintained in either wire cages (n = 11, 10 animals per cage) or floor pens (n = 11, 10 animals per pen) containing a deep litter of woodchips, both housing systems having the same dimensions (2 × 1 × 0.4 m). Growth traits, food intake and feed conversion ratio were recorded weekly and expressed as the difference between the two groups. After 77 days, the animals were slaughtered, and carcass traits were evaluated. Growth performance and carcass trait parameters, as well as mortality and behavior trends, were not affected by the housing system type. Nonetheless, the use of wire cages is recommended for raising guinea pigs since water, urine and feces pass through the wire floor, resulting in cleaner animals.
