Musculoskeletal evaluation of the lower pelvic complex in women with endometriosis: A case-control study.

OBJECTIVE: Use clinical pain measurement tools to investigate and compare the prevalence of pelvic loin disoders in women with and without endometriosis. STUDY DESIGN: Chronic pelvic pain (CPP) associated with endometriosis has diverse origins, including musculoskeletal factors. Musculoskeletal dysfunction in the pelvic region is theorized to result from sustained muscular contraction, triggered by altered visceral stimuli and adoption of antalgic postures, causing secondary damage to muscles, ligaments, and joints. CPP significantly impacts quality of life, relationships, sexuality, and mental health. However, limited data exists on musculoskeletal impacts of endometriosis and CPP. It was made a case-control study at Maternidade Escola Assis Chateaubriand from August 2017 to January 2021. Evaluated 71 women: 41 in endometriosis group (EG) and 30 in control group (CG). Data collection included sociodemographic questionnaires, musculoskeletal physiotherapeutic evaluations, pain mapping, pressure pain thresholds, kinesiophobia, and disability measurements. Statistical analysis was performed using Spearman's Rho test to determine correlations. RESULTS: Mean age of participants was 31 years. EG exhibited lower pain threshold variations in lumbopelvic trigger points than CG (P < .05). Significant muscle flexibility differences between groups were observed; EG had reduced flexibility (P < .05). Most common pain areas were hypogastrium in EG (48.78 %) and left lumbar in CG (30 %). EG had higher kinesiophobia values (P = .009). There was a weak association between kinesiophobia-pressure threshold association observed in CG's lumbar pelvic region. CONCLUSION: Women with Endometriosis and CPP exhibit higher prevalence of musculoskeletal disorder, lower pain thresholds, decreased lumbopelvic muscle range of motion, higher kinesiophobia scores, and increased disability indices with low back pain compared to healthy women.

A comparative genomics study of the microbiome and freshwater resistome in Southern Pantanal.

This study explores the resistome and bacterial diversity of two small lakes in the Southern Pantanal, one in Aquidauana sub-region, close to a farm, and one in Abobral sub-region, an environmentally preserved area. Shotgun metagenomic sequencing data from water column samples collected near and far from the floating macrophyte Eichhornia crassipes were used. The Abobral small lake exhibited the highest diversity and abundance of antibiotic resistance genes (ARGs), antibiotic resistance classes (ARGCs), phylum, and genus. RPOB2 and its resistance class, multidrug resistance, were the most abundant ARG and ARGC, respectively. Pseudomonadota was the dominant phylum across all sites, and Streptomyces was the most abundant genus considering all sites.

Occurrence of contaminants of emerging concern and their risks to the Pantanal Sul-Mato-Grossense aquatic biota, Brazil.

The Aquidauana River is an important ecological corridor in the Pantanal biome. However, the growth of agricultural and urban areas along its banks has contributed to the deterioration of its water quality, consequently putting the aquatic biota at risk. Our objectives were to evaluate: 1) the composition of the landscape around six sampling sites located in the Aquidauana River middle section; and 2) the quality of its water by determining limnological parameters, concentrations of contaminants of emerging concern (CECs), and the risks to native aquatic biota. Water samples were collected in November 2020. We observed the conversion of native riparian vegetation to extensive pasture areas and anthropic occupation around the sampling sites. We observed that the chlorophyll and total ammoniacal nitrogen values were above the standards established by Brazilian legislation in all samples. Studies focused on the quantification of CECs in the Pantanal waters are scarce, and to the best of our knowledge, this is the first study that investigated the presence of pharmaceuticals in the Aquidauana River. All 30 CECs analyzed were detected in at least one water sample. Eleven CECs were quantified with eight pesticides (atrazine, diuron, hexazinone, tebuthiuron, azoxystrobin, carbendazim, tebuconazole, and fipronil) and one atrazine degradation product (atrazine-2-hydroxy), caffeine, and bisphenol A. The concentrations of atrazine herbicide observed in the water samples pose risks for protecting aquatic biota (RQs >1). Therefore, the native biota of the Pantanal biome is vulnerable to several types of toxic contaminants observed in the water, which can cause the disappearance of native and endemic species in this region. Establishing a monitoring program, improving sanitation infrastructure, and intensifying good agricultural practices are essential for reducing and controlling the entry of CECs into the Aquidauana River and the Pantanal water system.

Effect of floating macrophyte cover on the water quality in fishpond - DOI: 10.4025/actascibiolsci.v25i1.2086 / Efeito da cobertura de macrófitas flutuantes na qualidade da água em um viveiro de piscicultura - DOI: 10.4025/actascibiolsci.v25i1.2086

A study was conducted during 23 days in order to evaluate the impact of floating aquatic macrophyte on the water quality of a fishpond. Water samples were collected in four points, three inside the pond and one in water inlet. Drastic reduction of dissolved oxygen was observed in the pond, down to 0.87 mg/L. No significant differences (P > 0.05) were observed for total CO2, nitrite and ammonia with respect to inlet water (P1) and inside the pond (P2, P3 e P4). Chlorophyll a displayed an inverse relationship with phosphorus. Among nitrogen compounds, ammonia presented the highest concentrations except in water inlet where nitrate was higher, 513.33 µg/l, as well as the highest conductivity values. The pH was slightly acid. The results obtained showed that the macrophyte cover promoted an adverse effect in the medium. Under control, aquatic plants might impact positively due to its capacity to reduce total phosphorus and nitrate in the water column as observed in this study

Com o objetivo de avaliar o impacto das macrófitas aquáticas flutuantes na qualidade da água em um viveiro de piscicultura, foi realizado um estudo durante 23 dias consecutivos com coletas de água realizadas em quatro pontos, sendo três dentro do viveiro e um à entrada de água. Foi verificada uma redução drástica do oxigênio dissolvido dentro do viveiro, chegando a 0.87 mg/L. Não foram observadas diferenças significativas (P > 0.05) para o CO2 total, nitrito e amônia em relação à água de entrada (P1) e à água do viveiro (P2, P3 e P2). A clorofila a apresentou uma relação inversa com o fósforo na água. Dentre os compostos nitrogenados, a amônia apresentou as maiores concentrações, com exceção do ponto de entrada (P1), em que o nitrato foi mais elevado, com 513.33 µg/L, apresentando os maiores valores para condutividade. O pH manteve-se ligeiramente ácido no viveiro, influenciando diretamente as concentrações de CO2 livre na água. Os resultados obtidos evidenciaram que a cobertura de macrófita flutuante promoveu um efeito adverso no meio. Se esta cobertura for utilizada de forma controlada, as plantas aquáticas poderão ter um efeito de impacto positivo, devido à capacidade de redução do fósforo total e nitrato na coluna dágua, como observado neste estudo
