Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

ABSTRACT Obesity is a chronic disease associated with impaired physical and mental health. A widespread view in the treatment of obesity is that the goal is to normalize the individual's body mass index (BMI). However, a modest weight loss (usually above 5%) is already associated with clinical improvement, while weight losses of 10%-15% bring even further benefits, independent from the final BMI. The percentage of weight reduction is accepted as a treatment goal since a greater decrease in weight is frequently difficult to achieve due to metabolic adaptation along with environmental and lifestyle factors. In this document, the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Society for the Study of Obesity and Metabolic Syndrome (ABESO) propose a new obesity classification based on the maximum weight attained in life (MWAL). In this classification, individuals losing a specific proportion of weight are classified as having “reduced” or “controlled” obesity. This simple classification – which is not intended to replace others but to serve as an adjuvant tool – could help disseminate the concept of clinical benefits derived from modest weight loss, allowing individuals with obesity and their health care professionals to focus on strategies for weight maintenance instead of further weight reduction. In future studies, this proposed classification can also be an important tool to evaluate possible differences in therapeutic outcomes between individuals with similar BMIs but different weight trajectories.

Abstract Specific pathogenic mutations associated with breast cancer development can vary between ethnical groups. One example is BRCA1 c.5266dupC that was first described as a founder mutation in the Ashkenazi Jewish population, but was later also found in other populations. In Brazil, this mutation corresponds to 20% of pathogenic BRCA1 variants reported. Our objective was to investigate the haplotype component of a group of Brazilian families who inherited c.5266dupC in the BRCA1 gene and to verify the ancestry contribution from European, African, and Amerindian origins. Fourteen probands carrying c.5266dupC and 16 relatives (carriers and non-carriers) were investigated. The same haplotype was observed segregating within all the families analyzed, revealing no recombinants in a region of 0.68 Mb. Ancestry analysis demonstrated that the European component was predominant among probands. The BRCA1 c.5266dupC analysis indicates that there was a founder effect in the Brazilian population.

Abstract Pathogenic microbial detection and control in laboratory animal facilities is essential to guarantee animal welfare, data validity and reproducibility. Helicobacter spp. are known to affect mice health, what may interfere with experimental outcomes. This study aimed to screen for Helicobacter spp. in mice from animal facilities in Rio de Janeiro, Brazil using a PCR-based method. Primers designed to specifically identify Helicobacter spp. were used to amplify feces or intestine DNA extracted of mice from four different animal facilities. The expected 375 base pairs (bp) amplicon was purified, sequenced and a similarity of 95% was observed when compared to deposited sequences of H. hepaticus and H. bilis. In our screening, Helicobacter spp. was detected in ~59% of fecal and ~70% of intestine samples. Our study is the first to screen for Helicobacter spp. in mouse facilities of a Rio de Janeiro University using a low cost, rapid molecular diagnostic test. Although Helicobacter spp. screening is not mandatory according to Brazilian animal welfare regulation it is recommended by institutional animal health monitoring programs guidelines worldwide, including ARRIVE, AAALAC and FELASA.

ABSTRACT Objective This study sought to investigate the effects of vitamin D supplementation and aquatic exercise on pulmonary function in postmenopausal women. Materials and methods This prospective and controlled study included 104 women (62 ± 6.5 years) divided into three groups: a control group lacking vitamin D and calcium supplementation which remained sedentary (CG; n = 17); a control group receiving vitamin D and calcium supplementation which remained sedentary (CDG, n = 33); and a group that completed aquatic exercises three times a week and received vitamin D and calcium supplementation (DTG, n = 54). Data before and after 6 months of the study were analyzed, including serum 25-hydroxyvitamin D (25(OH)D) and calcium concentrations, peak expiratory flow (PEF), forced vital capacity (FVC), and cirtometry. Results We observed significant increases in 25(OH)D concentrations in CDG (52.9 ± 2.4 to 69.1 ± 2.2; nmol/L; p < 0.0001) and DTG groups (55.5 ± 3 to 71.5 ± 3 nmol/L; p < 0.0001). PEF increased by 7 ± 2% (p = 0.0080) in CDG group and 11 ± 2% (p < 0.0001) in DTG group, whereas FVC increased by 7 ± 2% (p = 0.0016) in the CDG group and 10 ± 2% (p < 0.0001) in the DTG group, whereas CG had no changes in any of these parameters. The increment value of cirtometry in DTG group (+43 ± 3%) were significantly (p < 0.0001) higher than those in CG (−4 ± 8%) and CDG (+4 ± 9%) groups. Conclusion Our data suggest that vitamin D supplementation improves pulmonary function parameters in postmenopausal women.

A introdução da vacinação no mundo reduziu drasticamente a incidência de doenças causadas por bactérias e vírus patogênicos. Apesar das estratégias de vacinação de grande sucesso, o número de casos de doenças que podem ser prevenidas por vacinas tem aumentado na última década e algumas destas doenças permanecem endêmicas em diferentes países. Aqui discutimos alguns aspectos epidemiológicos e possíveis argumentos que possam explicar porque doenças da antiguidade como, sarampo, pólio, coqueluche, difteria e tuberculose, permanecem entre nós.

The introduction of vaccination worldwide dramatically reduced the incidence of pathogenic bacterial and viral diseases. Despite the highly successful vaccination strategies, the number of cases among vaccine preventable diseases has increased in the last decade and several of those diseases are still endemic in different countries. Here we discuss some epidemiological aspects and possible arguments that may explain why ancient diseases such as, measles, polio, pertussis, diphtheria and tuberculosis are still with us.

INTRODUÇÃO: Estudos prévios sugeriram que os níveis plasmáticos da retinol binding protein (RBP4), uma proteína do tecido adiposo, estão associados com a resistência à insulina (RI). A lipodistrofia congênita generalizada (LCG) é uma doença rara caracterizada por ausência de tecido adiposo e RI. O objetivo é determinar os níveis de RBP4 em pacientes com LCG. SUJEITOS E MÉTODOS: Seis (6) pacientes com LCG e um grupo controle saudável foram selecionados para participar no estudo. As variáveis antropométricas e bioquímicas foram comparadas quando comparados os grupos. RESULTADOS: Nenhuma diferença foi observada entre os níveis de RBP4 log entre os grupos (LCG 42,5 [12,5 - 127] vs. controle 57,4 [15,9 - 165]; p = 0,78). Por outro lado, os níveis de leptina foram menores em pacientes com LCG (LCG 0,65 [0,2 - 0,7] vs. controle 10.9 [0,9 - 38,6]; p = 0,015). Nenhuma correlação foi encontrada entre RBP4 e cintura (r = 0,18, p = 0,57) ou IMC (r = 0,24, p = 0,45). CONCLUSÃO: RBP4 não está diminuída na LCG. Esses resultados sugerem que o tecido adiposo pode não ser a principal fonte de RBP4.

INTRODUCTION: Previous studies have suggested that Retinol Binding Protein 4 (RPB4), a protein produced by the adipose tissue, is associated with insulin resistance (IR). Congenital Generalized Lipodystrophy (CGL) is a rare disease characterized by IR and paucity of adipose tissue. Our objective was to determine RBP4 levels in patients with CGL. SUBJECTS AND METHODS: Six (6) patients with CGL and a healthy control group were selected to participate in the study. Anthropometric and biochemical variables were compared between groups. RESULTS: No difference was observed in RBP4 levels between the two groups (CGL 42.5 [12.5 - 127] vs. control 57.4 [15.9 - 165]; p = 0.78). On the other hand, leptin levels were significantly lower in CGL patients (CGL 0.65 [0.2 - 0.7] vs. control 10.9 [0.9 - 38.6]; p = 0.015). No correlation was found between RBP-4 and waist circunference (r = 0.18, p = 0.57), or BMI (r = 0.24, p = 0.45). CONCLUSION: RBP4 is not decreased in CGL. These results suggest that adipose tissue may not be the main source of RBP4.

OBJETIVO: Avaliar o impacto dos sintomas depressivos e da dor neuropática na qualidade de vida (QV) de pacientes diabéticos com polineuropatia distal diabética (PNDD). MÉTODOS: Foram avaliados 204 pacientes com diabetes melito tipo 2. O diagnóstico de PNDD foi realizado por meio do Escore de Sintomas Neuropáticos e Escore de Comprometimento Neuropático. A gravidade da dor neuropática foi avaliada por meio da Escala Visual Analógica (EVA); os sintomas depressivos, por meio do Inventário Beck de Depressão (IBD); a QV, com o World Health Organization Quality of Life abreviado (WHOQOL-bref). RESULTADOS: Pacientes com PNDD apresentaram escores mais altos no IBD (12,6 ± 7,2 versus 9,9 ± 7,3; p = 0,018) e no EVA (5,0 ± 2,4 versus 2,6 ± 2,9, p < 0,001). Em relação à QV, apresentaram escores mais baixos no domínio físico (52,8 ± 15,5 versus 59,2 ± 17,0; p = 0,027) e ambiental (56,6 ± 12,3 versus 59,6 ± 13,6; p = 0,045). CONCLUSÕES: Pacientes diabéticos com PNDD apresentam pior QV nos domínios físico e ambiental do WHOQOL-bref, provavelmente devido à maior sintomatologia depressiva e gravidade de dor.

OBJECTIVE: To investigate the impact of depressive symptoms and neuropathic pain in the quality of life (QL) of diabetic patients with diabetic distal polyneuropathy (DDP). METHODS: Two hundred and four patients with type 2 diabetes mellitus were evaluated. The diagnosis of DDP was achieved using the Neuropathy Disability Score and Neuropathy Symptom Score questionnaires. The severity of neuropathic pain was assessed by means of a Visual Analogue Scale (VAS); the severity of depression, by means of the Beck Depression Inventory (BDI); and QL was assessed by means of the World Health Organization Quality of Life Instrument-bref (WHOQOLbref). RESULTS: Patients with DDP presented significant higher scores in BDI (12.6 ± 7.2 versus 9.9 ± 7.3; p = 0.018) and in VAS (5.0 ± 2.4 versus 2.6 ± 2.9; p < 0.001). They also presented significant lower scores in the physical (52.8 ± 15.5 versus 59.2 ± 17.0; p = 0.027) and environmental domains (56.6 ± 12.3 versus 59.6 ± 13.6; p = 0,045). CONCLUSIONS: Diabetic patients with DDP presented a worse QL in the physical and environmental domains of the WHOQOL-bref, probably due to more depressive symptoms and the severity of pain.

OBJECTIVES: Gemcitabine and cisplatin (GC) is an active combination in the treatment of metastatic bladder cancer. We have prospectively analyzed the efficacy and tolerability of GC as neoadjuvant treatment of invasive bladder cancer MATERIALS AND METHODS: In this single-institution phase II trial, patients with muscle-invasive transitional cell carcinoma received three cycles of gemcitabine 1200 mg/m² on days 1 and 8 with cisplatin 75 mg/m² on day 1 prior to surgery. Radiologic response was evaluated by computed tomography and magnetic resonance imaging. All patients were referred to surgery after chemotherapy completion RESULTS: Between June 2002 and March 2005, 22 patients (19 males) were enrolled. Median age was 63 years. Initial stage was II (T2) in 11 and III (T3-4) in 11 patients. Median follow-up is 26 months (4-43). Partial or complete radiologic response rate was documented in 13 out of 20 assessable patients (70%). One patient was excluded due to sarcomatoid carcinoma at definitive pathologic examination. Cystectomy was performed in 15 patients and pelvic radiotherapy in four patients. Nine out of 21 patients (43%) relapsed and four (19%) died due to disease progression. Complete pathologic response was observed in four patients (26.7% of 15). Median progression-free survival was 27 months (CI 95% not reached) with median overall survival of 36 months (CI 95%: 28.7 - 43.3). Grade III/IV toxicity was infrequent, with no deaths due to chemotherapy CONCLUSIONS: The combination of GC is effective and well-tolerated when used as neoadjuvant therapy in muscle-invasive bladder cancer. Longer follow-up is necessary to evaluate its impact on the overall survival of these patients.
