“…The Island of Caratateua, like the other inhabited islands in the capital of Pará, is characterized by having a socioeconomically vulnerable population, with the after-school program being a place of shelter and offering extracurricular activities mainly aimed at children from low-income and at-risk families. Historically, the area has experienced intense disorderly occupation by people looking for permanent or holiday housing, which has resulted in substandard housing ( 9 , 30 , 31 ).…”

IntroductionThe detection of leprosy in children is an important epidemiological marker of the disease, indicating the community’s early exposure to Mycobacterium leprae and active transmission of the infection.MethodsIn order to detect new cases among children by combining clinical evaluation and laboratory tests, we conducted an active case finding among individuals under 15 years old on Caratateua Island, located in the city of Belém, in the Pará state, an endemic region in the Amazon. Dermato-neurological examination, collection of 5 mL of peripheral blood for IgM anti-PGL-I antibody titration, and intradermal scraping for bacilloscopy and amplification of the specific RLEP region by qPCR were performed.ResultsOut of the 56 examined children, 28/56 (50%) new cases were identified. At the time of evaluation, 38/56 (67.8%) children presented one or more clinical alterations. Seropositivity was detected in 7/27 (25.9%) new cases and 5/24 (20.8%) undiagnosed children. DNA amplification of Mycobacterium leprae was observed in 23/28 (82.1%) of new cases and in 5/26 (19.2%) of non-cases. Out of the total cases, 11/28 (39.2%) were exclusively diagnosed by clinical evaluation performed during the active case finding. Seventeen new cases (60.8%) were detected considering the clinical alterations found in addition to positive results for qPCR. In this group, 3/17 (17.6%) qPCR-positive children presented significant clinical changes 5.5 months after the first evaluation.DiscussionOur research detected a number of cases 5.6 times higher compared to the total number of pediatric cases recorded throughout the year 2021 in the municipality of Belém, which shows a critical scenario of underdiagnosing of leprosy among children under 15 years old in the region. We propose the use of qPCR technique to identify new cases among children with oligosymptomatic or early disease in endemic areas, in addition to the training of Primary Health Care professionals and the implementation of the Family Health Strategy coverage in the visited area.

“…Na etapa para determinação da classificação do uso e ocupação do solo, foi realizada a composição falsa cor RGB 5, 4, 3 e 6, 5, 4 para imagens de satélites Landsat 5 e 8, respectivamente. Para a classificação do uso e ocupação do solo foi aplicada a técnica Máxima Verossimilhança (MAXVER), na qual se baseia na classificação, pixel a pixel da imagem, usando somente a informação espectral de cada pixel para identificar áreas homogêneas, em que se faz o procedimento de extração de informação em imagens para identificar elementos e objetos similares (Bentes et al, 2018).…”

This study had aimed to observe changes in land use and occupation and to associate with the surface temperature (ts) of the municipality of Pombal-PB for the period from 1986 to 2016. In this research, bands 3, 4 and 5 were used. TM / Landsat 5 sensor and OLI / Landsat 8 bands 4, 5 and 6 to analyze changes in land use and occupation. To determine the TS, two multispectral images (thermal infrared bands) were used, through TIRS sensors (thermal infrared sensor), referring to bands 6 and 10, Landsat 5 and 8, respectively, in which they have resolutions of 30 meters, for years 1986, 1996, 2006 and 2016. To determine the classes of land use and occupation, the maximum likelihood method (maxver) was applied. To measure the compositions of the classes determined by maxver, the statistical technique, Kappa index (k), was used. The results showed that in the surveyed time scale (1986 to 2016) that the classes of land use and occupation that showed growth were anthropized area (13.71%) and exposed soil (12.01%), in contrast, the Caatinga class thinning showed a reduction (48.76%). The results of the Kappa index indicated an excellent degree of performance for the four periods analyzed. The results showed that areas with vegetation (<28 °C) or close to bodies of water (28 to 32 °C) had the lowest average surface temperatures between the years 1986 to 2016.

This paper aimed at to evaluate the qualitative effects of climatic seasonality in a subtropical lagoon, using Discriminant Analysis, as well to identify the most sensitive and responsible parameters for these changes. The Mirim Lagoon watershed is one of the main transboundary basins in South America and is of great economic importance for the region because its waters are used for irrigation of rice fi elds and for the potable water supply to populations close to it, in this way, these uses may affect the quality of the basin waters. The data used in the study were provided and collected by the Mirim Lagoon Development Agency. Water quality parameters were selected in a fi ve-year database and submitted to statistical tests that demonstrated their distinctions throughout the climatic seasons. The results showed that the parameters temperature, pH, dissolved oxygen, biochemical oxygen demand, total nitrogen and total phosphorus differ statically between the four climatic seasons. Were also identifi ed four discriminative parameters between the seasons, being them dissolved oxygen, biochemical oxygen demand, total nitrogen and total phosphorus. In this way, it can be concluded that the seasonality mainly affects anthropogenic pollution sources such as agricultural activities and domestic discharges.
