title: Basal cell carcinoma of the areola: a rare case report

description: ABSTRACT Basal cell carcinoma (BCC) is the most common malignant cutaneous neoplasm. It is preferentially located in areas exposed to solar radiation, since the cumulative effect of ultraviolet radiation on susceptible individuals seems to be the major triggering factor. Among the places considered unusual are breasts and glutes. According to a survey conducted in 2016, there are only 55 cases of BCC in the nipple-areola complex described in the literature. In the present report, we have a patient with areolar BCC and discuss the importance of a thorough dermatological examination.

title: Alpha and beta diversities of Trichoptera (Insecta) assemblages in natural and rural subtropical streams

description: Abstract: Aim The aim of this study was to determine the diversity of Trichoptera in subtropical streams and the effects of environmental variables and geographical position on alpha and beta diversity in natural and rural streams. Methods We collected Trichoptera with a Surber sampler in 12 small order subtropical streams (six streams with apparent absence of anthropic disturbance and six streams with rural activity in their drainage areas) and measured limnological variables. We evaluated the effects of environmental variability and geographical distance on the dissimilarity of the assemblage and calculated the contribution of alpha and beta diversity for each stream. Results We collected a total of 1,264 Trichoptera larvae distributed in 17 genera and 11 families. The genera Phylloicus and Smicridea were found in almost all streams. We observed a positive effect of environmental variability on biological variability but not of geographical distance. The environmental variability was basically generated by the influence of higher concentrations of dissolved organic carbon and nutrients. We observed the greatest contribution of the alpha diversity of the Trichoptera assemblages in natural streams and of beta diversity in the rural streams. Conclusions Our results demonstrate that the variability of Trichoptera is affected by environmental characteristics, but not by geographical position.

title: Nonconformities in clinical laboratories in Macapá, Amapá, Brazil, based on the RDC no. 302/2005/Anvisa

description: ABSTRACT Introduction: Clinical analysis laboratories are health care facilities that provide resources for outpatient and/or emergency diagnoses; they are regulated in Brazil by the Resolution of the Collegiate Board of Directors (RDC) no. 302, of October 13, 2005, of the Brazilian National Agency of Sanitary Surveillance (Anvisa). Objective: The aim of this study was to perform a normative evaluation in clinical analysis laboratories, based on RDC no. 302, of October 13, 2005. Material and method: This is a cross-sectional and descriptive study. Twelve clinical laboratories participated in the study. The data were obtained through a structured questionnaire and answered by the technical leaders of the participating laboratories, in the municipality of Macapá, Amapá, Brazil. Results: The average nonconformity found among the participants was 9.64%, which allowed an overall evaluation among them as satisfactory, in relation to the minimum requirements demanded by the standardization recommended by Anvisa. When the participants were analyzed individually, there was a variation from 4.82% to 21.69% of the nonconformities index. Other studies agree with the results, however there is disagreement in a research carried out in Porto Alegre, Rio Grande do Sul, Brazil, possibly due to the fact that the laboratories present in this study do not have a quality management system in their processes. Conclusion: Laboratories 2, 3, 4, 6, 9, 11, and 12 were rated as satisfactory. Laboratories 1, 5, 7, 8 and 10 were rated as partially satisfactory. No laboratories were rated as unsatisfactory.

title: Record of parasitic oomycetes on neotropical copepods in aquatic environments of Northwestern Patagonia (Argentina)

description: Abstract: Aim Oomycetes are one of the most widespread and destructive parasitic groups in the world. The first infection of oomycetes on copepod Parabroteas sarsi Daday 1901 was recently recorded in America. Oomycetes infection on this species makes their eggs unviable and could differentially affect the survival of females. The aim of this study was to track the incidence of oomycetes in two populations of P. sarsi. Methods Two Patagonian ponds were monitored during spring-summer of 2014-2018, measuring environmental variables and the prevalence of oomycete infections on P. sarsi populations. Taxonomic determination of the oomycetes was performed in laboratory. Sex ratios also were recorded in each survey. Results The presence of Aphanomyces ovidestruens Gicklhorn 1923 and Pythium flevoense Van der Plaats-Niterink 1972 was detected in females of P. sarsi in both ponds. We observed a decrease in the parasite prevalence over time, from ~25% (assessed on the total number of adults) to almost disappear completely. Besides, a lower proportion of females than males were observed in samples with high prevalence of parasitism. No temperature differences were found during the sampling years and the monthly temperatures between the maximum and minimum prevalences were similar. Conclusions Our study presents a new record of oomycetes parasitizing copepods in America. Temperature can play a key role in the dynamics of parasite species, but in our study this variable not affected the incidence of the infection. However, other variables could be affect the pattern of the infection such as the presence of predators of oomycetes spores (cladocerans). The lower females proportion when the infection was higher, could support the idea of differential sex/mortality induced by the infection. Recording and identification of parasites is a critical starting point for wildlife management, which will provide an early warning to prevent the spread of harmful parasites such as oomycetes.

title: Quality of life and osteomuscular symptoms in workers of primary health care

description: ABSTRACT Objectives: to evaluate the quality of life and musculoskeletal symptoms in primary care workers. Methods: descriptive, correlational and cross-sectional study with 85 workers using the WHOQOL-Bref and Nordic Osteomuscular Symptoms Questionnaire. Results: lower quality of life for the Environment domain and higher for Social Relationships. Workers reported pain in lower back, neck, shoulders, wrists/hands/fingers and knees. Neck pain influenced Physical (p=0.015) and Psychological (p=0.030) domains; shoulder pain (p=0.004) and dorsal region (p=0.013) influenced the Physical domain; pain in knees influenced Physical (p=0.000) and Environment (p=0.032) domains; pain in the ankles/feet influenced Physical (p=0.000), Psychological (p=0.032) and Environment (p=0.007) domains; pain in the dorsal region influenced the Physical domain (p=0.013). Conclusions: workers evaluated their quality of life as good or very good and reported to be satisfied or very satisfied with their health. They also reported pains in lower back, neck, shoulders, wrists/hands/fingers and knees. Pain has influenced the quality of life.

title: COVID-19: clinical and laboratory manifestations in novel coronavirus infection

description: ABSTRACT COVID-19 is a highly contagious disease caused by the coronavirus of severe acute respiratory syndrome 2 (SARS-CoV-2). In 2020, due to the outbreak, it was considered by the World Health Organization (WHO) as a pandemic. The infection caused by the novel coronavirus has high mortality in a small portion of the infected population, especially in elderly, immunosuppressed, diabetic, cardiac, and hypertensive individuals. Many infected are asymptomatic (and may be carriers) or present mild or moderate flu-like symptoms. The most severe clinical picture of COVID-19 is characterized by an inflammatory cytokine storm, with hematological changes and coagulation dysfunction, which can lead to tissue damage and death. Nonspecific laboratory biomarkers may be either increased or decreased as the course of the disease progresses and are often useful in predicting complications of the disease, such as the use of D-dimer and platelet/lymphocyte ratio. Specific laboratory diagnosis is based on the detection of viral ribonucleic acid (RNA) by real-time polymerase chain reaction (RT-PCR) of nasal and oropharyngeal swab samples; it is more effective when performed in the first days after symptom onset. Serological tests are useful in detecting the immune response, since both class M (IgM) and class G (IgG) immunoglobulin antibodies can be detected seven days after the onset of clinical symptoms, and may extend for more than 25 days, although not exempting the individual from remaining infectious, depending on their viral load and clinical presentation. The rational use of specific laboratory markers must respect the disease chronology, and the correct interpretation may provide subsidies for a better management of affected patients, as well as identifying asymptomatic carriers or those with mild symptoms.

title: Synthesis of Aurivillius Phase CaBi4Ti4O15 Doped with both La3+ and Mn3+ Cations: Crystal Structure and Dielectric Properties

description: Abstract The four-layer Aurivillius CaBi4Ti4O15 with introducing of La3+ on the A-site and Mn3+ on the B-site with the formula Ca1-xBi3+xLaTi4-xMnxO15 (x = 0, 0.2, 0.4, 0.6, 0.8, and 1) were synthesized by molten salt method using the mixture of sulfate salts K2SO4/Na2SO4 as the flux. XRD data confirmed the formation of single-phase Aurivillius with A21am orthorhombic structure for x = 0, 0.2, 0.4, and 0.6, whereas for x = 0.8 and 1, the impurity phases were observed. SEM analysis shows the anisotropic plate-like grains, which are a typical grain of Aurivillius phases. The cell volume decreases with increasing x, indicating a presence of mixed valences of Mn3+ and Mn4+. The dielectric constants increased with x, strongly correlated with the higher distortion of the structure, the 6s2 lone pair electrons of Bi3+ cation increase. The presence of Mn3+ unpaired electrons results in the increase of dielectric loss as increasing x.

title: Peripheral venous access using devices over needles with and without extension: costs and outcomes

description: ABSTRACT Objectives: to analyze the mean direct cost and peripheral venous access length outcomes using devices over needle with and without extension. Methods: quantitative, exploratory-descriptive research. Venous punctures and length of the devices were followed. The mean direct cost was calculated by multiplying the time (timed) spent by nursing professionals by the unit cost of labor, adding to the cost of materials. Results: the total mean direct cost of using devices “with extension” (US$ 9.37) was 2.9 times the cost of using devices “without extension” (US$ 4.50), US$ 7.71 and US$ 2.66, respectively. Totaling 96 hours of stay, the “device over needle with extension” showed a lower occurrence of accidental loss. Conclusions: the use of the “device over needle with extension”, despite its higher mean direct cost, was more effective in favoring adequate length of peripheral venous access.

title: Evaluation of quality indicators of cervical cytopathology tests carried out in a municipality of Paraná, Brazil

description: ABSTRACT Introduction: Although the criteria and recommendations are well defined to improve the quality of cervical cytopathology tests (Pap smear) in Brazil, the quality indicators of several laboratories are below the recommended standards. Objective: To evaluate the quality indicators of cervical cytopathology tests carried out by the Brazilian Unified Health System [Sistema Único de Saúde (SUS)]. Method: Cross-sectional study based on the results of cervical cytopathology tests conducted in the municipality of Cascavel, Paraná, Brazil, from January 2012 to December 2018. The study included 141,191 tests and the following variables were analyzed: sample suitability, cervical cytopathology tests result, and internal quality monitoring indicators recommended by the Brazilian Ministry of Health. Results: The percentage of unsatisfactory tests did not exceed 0.97%. The representation of the squamocolumnar junction ranged from 63% to 67.4%. The percentage of altered exams among the satisfactory samples ranged from 0.46% to 6.44%. The positivity index ranged from 0.46% to 6.44%, while the high-grade squamous intraepithelial lesion/satisfactory indicator ranged from 0.21% to 1.06%, atypical squamous cells of undetermined significance/altered ranged from 22.47% to 49.93%, atypical squamous cells of undetermined significance/satisfactory ranged from 0.1% to 2.57%: and atypical squamous cells of undetermined significance/squamous intraepithelial lesions ranged from 0.31 to 1.02. Conclusion: In 2012 and 2013, the high-grade squamous intraepithelial lesion/satisfactory and the positivity index indicators were below the recommended parameters, and in the remaining years, these indicators were within the parameters recommended. Consequently, a greater number of truly cancer precursor lesions were identified, demonstrating the importance of internal quality control in the prevention of cervical cancer.

title: Chemical Attributes and Carbon Fractions in Serra de Itabaiana National Park

description: Abstract This study aimed to assess soil chemical attributes, organic matter fractions and carbon stocks of forest in three different regeneration stages in the Serra de Itabaiana National Park, Sergipe. The study was conducted in three areas: open white sands, intermediate white sands, and closed white sands, with a history of differentiated degradation. Soil samples were collected at 0-20 cm depth for chemical characterization and for fractionation of soil organic matter and C stock. The open white sands obtained the best results regarding levels of macronutrients, total organic carbon, and total soil nitrogen, as well as higher carbon/nitrogen ratio compared with intermediate white sands and closed white sands, with such effects being attributed to recent exposure to fire. Carbon concentrations in humic fractions of organic matter were little influenced by different vegetation in regeneration, except the carbon fraction of humic acid, which is more sensitive to different management and soil usage.
