A comparative study of three fishery methods for sampling the invasive topmouth gudgeon (Pseudorasbora parva) in ponds.

Invasive fish threaten ponds' ecological status and their ecosystem services, therefore obtaining a representative sample of fish community composition is fundamental to fishery management, research and nature conservation. Estimates of the size distribution, density and biomass of the topmouth gudgeon (Pseudorasbora parva) model species of invasive fish in three ponds were compared among three sampling methods: electrofishing, fish-trapping and throw-netting. The study illustrates that the invasive fish, P. parva, can be detected by all tested fishing methods, yet our results clearly showed that there are pronounced differences among methods in population characteristic estimates. Electrofishing and throw-netting gave biased information on the size distribution of P. parva. Fish-trapping and throw-netting gave reasonable P. parva density and biomass estimates, while electrofishing clearly underestimated it. All tested methods showed a body size increment of P. parva between summer and autumn sampling sessions, yet neither throw-netting nor electrofishing recorded an increment in its density. Our study showed that fish-trapping is the most reliable and affordable method to estimate invasive P. parva population characteristics in ponds despite more time-demanding sampling. The success depends on the mesh size of sampling gear, operator skill and habitat structure. The cost-effectiveness of the selected methods and the importance of invasive fish monitoring in ponds is discussed. The sampling gear must be considered carefully according to the aim of the monitoring.

Resumen Objetivo: Comparar características poblacionales y hallazgos placentarios asociados a óbito, en mujeres con infección asintomática por coronavirus 2 del síndrome respiratorio agudo grave (SARS-CoV-2) al momento de la resolución del embarazo. Material y métodos: Estudio transversal analítico, mujeres con diagnóstico de óbito e infección asintomática por SARS-CoV-2. Se excluyeron pacientes con patología ginecológica y aquellas con más de una prueba RT-PCR. Resultados: No hay diferencia estadísticamente significativa entre las pacientes con infección asintomática por SARS-CoV-2 comparadas con pacientes sin infección para las características poblacionales como edad materna, antecedentes obstétricos, edad gestacional, escolaridad, estado civil, hábito tabáquico y enfermedades crónico-degenerativas. Tampoco hubo diferencia en los hallazgos placentarios de corioamnionitis, vasculitis, deciduitis, trombosis, aterosis aguda y necrosis fibrinoide. Conclusiones: No hay diferencia estadísticamente significativa en las características poblacionales y placentarias en embarazadas con diagnóstico de óbito, con y sin infección asintomática por SARS-CoV-2. Tenemos datos insuficientes para afirmar alguna característica asociada a óbito en pacientes con infección por SARS-CoV-2 asintomática.

Abstract Objective: To compare population characteristics and placental findings associated with stillbirth, in women with asymptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection at the time of delivery. Materials and methods: Analytical cross-sectional study women with a diagnosis of stillbirth and with asymptomatic SARS-CoV-2 infection. Patients with gynecological pathology and those with more than one RT-PCR test were excluded. Results: There is no statistically significant difference between patients with asymptomatic SARS-CoV-2 infection compared to patients without infection for population characteristics such as maternal age, obstetric history, gestational age, education, marital status, smoking habit, chronic-degenerative diseases. There was no difference in placental findings of chorioamnionitis, vasculitis, deciduitis, thrombosis, acute atherosis, and fibrinoid necrosis. Conclusions: There is no statistically significant difference in the population and placental characteristics, in pregnant women diagnosed with stillbirth with and without confirmed asymptomatic SARS-CoV-2 infection. For the moment, we have insufficient data to affirm any population characteristic associated with stillbirth in patients with asymptomatic SARS-CoV-2 infection.

Trajectory of the development of caries in the permanent dentition of 12- to 16-year-old students based on a latent class growth model analysis in Liuyang / 口腔疾病防治

Objective@# To explore the trajectory of the development of permanent caries in 12- to 16-year-old students in Liuyang and to provide a reference for the prevention and management of caries.@*Methods@#Primary and secondary school students who were registered within the Liuyang jurisdiction were screened for caries from September to November by the Liuyang Center for Disease Control and Prevention. A total of 7 297 students between the ages of 12 and 16 years with complete permanent dentition caries monitoring records and traceable deciduous dentition caries monitoring records were selected from 2013 to 2019, and a zero-inflated negative binomial-latent class growth model (ZINB-LCGM) was established to describe the trajectory of the development of individual caries using the decayed missing filled teeth (DMFT) indicators. @*Results@# DMFT of 12- to 16-year-old students in Liuyang were mainly decayed teeth (DT), with the majority occurring in the first permanent molar. According to the ZINB-LCGM model, the students were classified into three latent categories, "slow growth pattern" (28.55%), "rapid growth pattern" (6.59%), and "stable pattern" (64.86%), which followed different nonlinear caries growth trajectories. Females with deciduous teeth caries were more likely to have trajectories showing a “rapid growth pattern” and a “slow growth pattern”. There were significant differences in the trajectories between men and women, as well as between those with and without primary dentition caries. @*Conclusion @# The trajectory of the development of caries in 12-16-year-old students shows heterogeneity in terms of different developmental patterns of latent categories, suggesting that females with deciduous dental caries should receive more attention.

Characteristics, efficacy and influencing factors of RA patients treated with iguratimod in the real world / 西安交通大学学报(医学版)

【Objective】 To conduct a retrospective study of the population characteristics, efficacy and influencing factors of rheumatoid arthritis (RA) patients who received iguratimod (IGU) treatment for at least 6 months from July 2015 to October 2020 and had more than 3 follow-up records. 【Methods】 In this study, 105 patients with RA were enrolled, and all the patients received IGU treatment for at least 6 months and were followed up three times. We observed their clinical manifestations before and after treatment, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), disease activity index (DAS28), rheumatoid factor (RF), anticyclic citrullinated peptide (ACPA), immunoglobulins (IgG, IgA, and IgM), lymphocyte subsets, and observed and recorded adverse reactions. 【Results】 The course of disease and the positive rate of ACPA were significantly lower in IGU group than in the group of IGU combined with (MTX) treatment (P<0.05). The DAS28-ESR of the patients in IGU group was significantly lower than that in the IGU+MTX treatment group and IGU+leflunomide (LEF) treatment group (P<0.05). After 6 months of continuous treatment, visual analogue scale/score (VAS), CRP and DAS28 (ESR/CRP) in IGU group were significantly reduced. As the treatment time was extended to one year, the above indicators further improved, and the number of joint swelling (SW) and the number of joint tenderness (TEN) also significantly improved. After one year’s continuous treatment, the incidence of adverse reactions in IGU group was 32.3%(10/31). 【Conclusion】 For RA patients with early onset, short-course, and antibody-negative, IGU is an effective therapeutic drug and a treatment option for RA patients with interstitial lung disease. IGU is well tolerated and is also an effective and a safe combination therapy option.

Changing ethnic and clinical trends and factors associated with successful home haemodialysis at Auckland District Health Board.

BACKGROUND: The health and diversity of the population in New Zealand (NZ) is changing under the influence of many socio-economic factors. This may have shifted the landscape of home haemodialysis (HHD). AIMS: To examine the demographic and clinical changes, determinants of HHD training and technique outcome and mortality between 2008 and 2015 at Auckland District Health Board, NZ. METHODS: We compared three incident cohorts of HHD patients between 2008 and 2015. Relevant factors, including demographic and clinical characteristics, training failure, technique failure and mortality were recorded. Factors associated with training and technique failure were examined by multivariate logistic regression. RESULTS: Of 152 patients, 133 completed training, 13 (10%) experienced technique failure and 15 (11%) died. Significant changes in ethnicity (increased: Maori 1.7-fold, Asian 1.7-fold and Pasifika 1.4-fold; decreased: NZ European 2.7-fold, P = 0.001), and major comorbidities, ≥2 major comorbidities (1.8-fold increase, P = 0.03), diabetes (2.1-fold increase, P = 0.013) and heart failure (P = 0.04) were seen. HHD as first renal replacement therapy modality increased 15-fold (P = 0.0001) and training time increased by 4.5 weeks (P = 0.004). Death and technique failure were unchanged over time. Shorter training time, employment and lower C-reactive protein were associated with 'Successful HHD'. 'Unsuccessful HHD' patient characteristics differed by ethnicity. CONCLUSIONS: The HHD population has become more representative of the NZ population, but significantly more comorbid over time. Patient training time has increased, but mortality and technique failure remain stable. 'Successful HHD' is predicted by social and clinical factors, and 'unsuccessful HHD' may have different mechanisms in different patient groups.

Analysis of the clinical characteristics of perianal fistulising crohn's disease in a single center / Análise das características clínicas da doença de crohn fistulizante perianal em um único centro

ABSTRACT Background: Clinical characteristics are keys to improve identification and treatment of Crohn´s disease (CD) so that large sample analysis is of great value. Aim: To explore the clinical characteristics of perianal fistulising CD. Methods: Analysis of 139 cases focused on their clinical data. Results: The proportion of males and females is 3.3:1; the mean age is 28.2 years; 47.5% of patients had anal fistula before CD diagnosis. Patients with prior perianal surgery and medication accounted for 64.7% and 74.1% respectively. The L3 type of lesion was present in 49.6% and the B1 and B2 types for 51.8% and 48.2% respectively; complex anal fistula was diagnosed in 90.6%. Symptoms of diarrhea were found in 46% and perianal lesions alone in 29.5% of patients. Abnormal BMI values was present in 44.6%; active CD activity index in 64.7%; and 94.2% had active perianal disease activity index. A proportion of patients manifest abnormal C-reactive protein, erythrocyte sedimentation rate, platelet, hemoglobin and albumin. Conclusion: We suggest that patients with anal fistula associated to these clinical features should alert the medical team to the possibility of CD, which should be further investigated through endoscopy and imaging examination of alimentary tract to avoid the damage of anal function by routine anal fistula surgery.

RESUMO Racional: As características clínicas são fundamentais para melhorar a identificação e o tratamento da doença de Crohn (DC), de modo que a análise da amostra seja de grande valor. Objetivo: Explorar as características clínicas da DC fistulizante perianal. Métodos: Análise de 139 casos focados em seus dados clínicos. Resultados: A proporção de homens e mulheres foi de 3,3: 1; a média de idade de 28,2 anos; 47,5% dos pacientes tiveram fístula anal antes do diagnóstico de DC. Pacientes com cirurgia perianal prévia e medicação representaram 64,7% e 74,1%, respectivamente. O tipo de lesão L3 estava presente em 49,6% e os tipos B1 e B2, em 51,8% e 48,2%, respectivamente; fístula anal complexa foi diagnosticada em 90,6%. Sintomas de diarréia foram encontrados em 46% e lesões perianais isoladas em 29,5% dos pacientes. Valores anormais de IMC estavam presentes em 44,6%; índice de atividade DC ativa em 64,7%; e 94,2% tinham índice de atividade de doença perianal ativo. Proporção significativa de pacientes tinha proteína-C reativa, taxa de sedimenta do eritrócito, plaquetas hemoglobina e albumina anormais. Conclusão: Sugere-se que pacientes com fístula anal associada às essas características clínicas alertem a equipe médica para a possibilidade de DC, que deve ser investigada por endoscopia e exame de imagem do trato digestivo para evitar dano na função anal pela operação que rotineiramente é realizada no tratamento da fístula anal.

Comparing schizophrenia symptoms in the Iban of Sarawak with other populations to elucidate clinical heterogeneity.

INTRODUCTION: The symptom profile of schizophrenia can vary between ethnic groups. We explored selected symptom variables previously reported to be characteristic of schizophrenia in the Iban of Sarawak in transethnic populations from Australia, India, and Sarawak, Malaysia. We tested site differences to confirm previous research, and to explore implications of differences across populations for future investigations. METHODS: We recruited schizophrenia samples in Australia (n = 609), India (n = 310) and Sarawak (n = 205) primarily for the purposes of genetic studies. We analyzed seven identified variables and their relationship to site using logistic regression, including: global delusions, bizarre delusions, thought broadcast/insertion/withdrawal delusions, global hallucinations, auditory hallucinations, disorganized behavior, and prodromal duration. RESULTS: We identified a distinct symptom profile in our Sarawak sample. Specifically, the Iban exhibit: low frequency of thought broadcast/insertion/withdrawal delusions, high frequency of auditory hallucinations and disorganized behavior, with a comparatively short prodrome when compared with Australian and Indian populations. DISCUSSION: Understanding between-site variation in symptom profile may complement future transethnic genetic studies, and provide important clues as to the nature of differing schizophrenia expression across ethnically distinct groups. A comprehensive approach to subtyping schizophrenia is warranted, utilizing comprehensively ascertained transethnic samples to inform both schizophrenia genetics and nosology.
