Belém Metropolitan Region has few and incomplete informations about production and destination of sewage sludge, because just little part of the sludge generated in septic tank and collective Sewage Works is throwed away without control in Aurá Sanitary Landfill. Because of this, is usual to throw the sludge in water bodies and in the ground, worsen the problems of pollution/contamination in the urban areas. Therefore, this work has the objective of analyzing the increase of production of sludge and evaluate the impact in the Aurá Sanitary Landfill. The search was developed in Belém Metropolitan Region, composed by Belém, Ananindeua, Benevides, Marituba and Santa Bárbara do Pará. It was divided in 2 stages. In the first stage it was estimated the production of the sludge (brute and drained) of septic tanks and in the collective Sewage Works during 2009 to 2030, and the second one was the availability of an area to disposal in the Aurá Sanitary Landfill. In the period studied, it was verified that by the way of the increase of the content of sludge drainage doesn’t has too many impact in the content of the residence solid waste, the deficiency of the available areas in the Aurá Sanitary Landfill is a problem that has to be solved as soon as possible, otherwise residence solid waste and sewage sludge produced in Belém Metopolitan Region won’t be well disposal, as a matter of fact that the prevision is the fast implicate of the free content of Aurá Sanitary Landfill.

Waste management is one of the main challenges of modern society, especially when it comes to finding more sustainable and economical alternatives for the treatment and disposal of these materials. In this context, biosolids, a byproduct generated from wastewater treatment, have been identified as a possible source of nutrients and organic matter for agriculture and other sectors, thus contributing to a more circular economy. Biosolids contain a large amount of nutrients that can be used to improve soil quality and increase agricultural productivity (OLIVEIRA et al., 2018). In addition, the use of biosolids as fertilizer can reduce the need for chemical inputs, contributing to the reduction of the environmental impact associated with final disposal (RIBEIRO et al., 2015). This study was conducted in a mining company in the state of Pará, Brazil, which has eight decentralized anaerobic wastewater treatment plants. The study aimed to define the treatment route for biosolids, as well as to evaluate the economic viability of implementing a drying bed for the production of biosolids to be applied in the restoration of degraded areas. It was found that 11,776 kg of total suspended solids (TSS) per year of sludge are generated, resulting in the design of a drying bed with three cells, each with 22 m², an operation cycle of 25 days, and a Surface Application Rate of 13.30 Kg TSS/m²xdia. For sanitization, CaO was chosen. The implementation cost of the drying bed was R$ 100,358.70, operational costs were R$ 2,059.62/month, and the solution via incineration was R$ 18,415.80/month. Based on the simple and discounted payback, the investment returns in approximately 7.14 and 7.19 months, respectively, and is part of the synergistic costs with the current sanitation management. The other indicators point to the investment as viable and capable of financial surplus. Therefore, the company will have financial and environmental gains with the implementation of the project.

Protocolo de diagnóstico e tratamento da hipertensão arterial sistêmica no Diabetes Mellitus
(Universidade Federal do Pará, 2024-02-23) OLIVEIRA, Cássio Antônio Bezerra de; QUEIROZ, Natércia Neves Marques de; http://lattes.cnpq.br/5359261920325026; FELÍCIO, João Soares; http://lattes.cnpq.br/8482132737976863
Hypertension is a chronic disease that often accompanies diabetes mellitus and the relationship between the two is complex. Like diabetes, it is an important cardiovascular risk factor and microvascular complications, such as nephropathy and retinopathy, and has higher health costs than diabetes itself. The treatment of hypertension in diabetes has been widely debated and there is still a need to reach a consensus on treatment goals and strategies. The objective of the present study was to develop a clinical protocol on the diagnosis and treatment of hypertension in diabetes mellitus whose main foundation was its applicability in the Brazilian public health system, focusing on medical adherence to recommendations, the impact of applying the evidence in primary and secondary care, and the evolution of health quality in these scenarios. To this end, an integrative literature review was carried out, selecting health articles based on the quality of evidence located in the PUBMED database and published in the last 20 years (2004-2024). Five researchers were responsible for selecting those with the best quality of evidence. National and international guidelines and works published by the UFPA diabetes clinical research group were also used. In the end, 106 articles were selected as theoretical references for preparing the protocol. The results were synthesized in the form of a clinical protocol containing concise texts and teaching resources (27 tables, 3 flowcharts and 1 figure) that will guarantee safety in clinical decision-making in primary and secondary health care settings, configuring a practical guide on the topic in question.

Diabetic neuropathy (DN) is currently the most frequently observed chronic complication of diabetes mellitus (DM) and, at the same time, the most underdiagnosed, affecting up to half of these patients, depending on the diagnostic methodology used. It generally affects individuals with a long duration of the disease (>10 years), however, it may be present at diagnosis in patients with DM2 or manifest early, within the first five years of the disease, in patients with DM1. Additionally, once diagnosed, DN is usually irreversible, but its appropriate management in patients with early diagnosis increases the possibility of regression and stabilization of the disease, considerably delaying and preventing the onset of complications. The objective of this work was to create a protocol for diagnosing and treating diabetic neuropathy in an objective and didactic manner, with a focus on helping general practitioners and specialists, both in primary and tertiary care. The protocol was prepared using the integrative literature review method, which was divided into 6 phases. The first phase consisted of preparing the guiding question to define the studies to be included and then an integrative review was carried out in the PUBMED and SciElo databases with the terms “NEUROPATHY”, “TREATMENT”, “DIAGNOSIS”, “NEUROPATHY DIABETIC” and its counterparts in Portuguese. Guidelines from the main national and international diabetes scientific societies, one book and relevant information from relevant websites were also included. After data collection and analysis, 106 materials were used as theoretical references for the preparation of this protocol. This resulted in the construction of didactic and objective tables, charts and flowcharts. The clinical applicability of the study consists of providing a tool, not only for the specialist, but for the general practitioner at different levels of health care, with the aim of enabling effective care for individuals with DN. Thus, the main contributions of the protocol were the development of a total of 20 didactic and visual tools aimed at the prevention, tracking, diagnosis and treatment of DN. 5 flowcharts, 4 charts and 2 tables are authored by the author.

Fear of animals and insects is a widespread condition that affects thousands of people around the world. The disease can be so severe that it interferes considerably with a person's daily life. This study aimed to examine the limitations and perspectives of clinical experts on the application of augmented reality (AR) in the treatment of phobias. The methodology used was action research, involving cooperation and participation between researchers and participants, enabling the analysis and resolution of problems in the clinical context. Information was collected through semi-structured interviews with therapists focused on specific phobias. Thematic analysis of the data revealed main and secondary themes, addressing clinical needs, software requirements, and feasibility of implementing AR in the treatment of phobias. Based on the identified requirements, augmented reality scenarios were created and the FobiAR mobile application was developed. The findings demonstrated that AR may be a promising alternative to conventional exposure therapy, offering a more immersive and controlled environment to patients. The FobiAR application received validation from the interviewed professionals, indicating potential for clinical application.
