Purpose: The household composition is important for adolescents and understanding its relationship with their lifestyle habits is essential. This study aimed to analyze the relationship of household composition with sedentary behavior and eating habits of adolescents. Methods: This study analyzed data from the Brazilian National Scholar Health Survey—PeNSE 2015. The sample was composed by 102,072 adolescents (11–17 years). The independent variable of the study was the household composition (living with both parents versus living with only one parent or none of them), whereas outcome variables were eating habits and sedentary behavior patterns. Logistic regression models were used to analyze the association between variables. Results: Adolescents living with both parents were less likely to have high sedentary behavior (≥2 h OR = 0.89; ≥4 h OR = 0.86), eat while watching TV for ≥5 days/week (OR = 0.88), frequent fried foods (OR = 0.89), sweets (OR = 0.92), soft drinks (OR = 0.86) and ultra processed foods (OR = 0.97) consumption, as were more likely to have lunch with parents (OR = 1.87), frequent vegetables (OR = 1.12), beans (OR = 1.14) and fruits (OR = 1.11) consumption than those who live with one parent or none of them. Conclusion: Households composed by both father and mother was associated with lower sedentary behavior and healthy eating habits in Brazilian adolescents. [ABSTRACT FROM AUTHOR]

Marsupials belonging to the Didelphis genus are widely distributed in the American Continent, and Didelphis albiventris and Didelphis aurita, are common in all of their areas of distribution in Brazil. Here we describe the bacterial and viral diversity of samples from opossums captured in three forest fragments in the State of São Paulo, Brazil. Microbiomes from the same body site were more similar across species and sampling sites while oral swabs presented higher bacterial diversity than rectal swabs. We also identified sequences related to bacterial species involved in zoonotic diseases. The detection of pathogens in such abundant mammal species warns for the possibility of emergence in other species. [ABSTRACT FROM AUTHOR]

The parasitoid wasps Clistopyga misionensis Bordera & Sääksjärvi and Hymenoepimecis pucallpina Pádua & Sääksjärvi were described recently and were known only from Peru and Argentina, respectively. The males of both species remain unknown. Here, we provide the first record of H. pucallpina for Brazil, Mato Grosso, and its male is described and illustrated for the first time. We also provide a new distribution record of C. misionensi for Brazil, Minas Gerais. A distribution map and images are provided. [ABSTRACT FROM AUTHOR]

Background: The first case of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection in Rio Grande do Norte, northeastern Brazil, was diagnosed on March 12, 2020; thereafter, multiple surges of infection occurred, similar to what was seen elsewhere. These surges were mostly due to SARS-CoV-2 mutations leading to emergence of variants of concern (VoC). The introduction of new VoCs in a population previously exposed to SARS-CoV-2 or after vaccination has been a challenge to understanding the kinetics of the protective immune response against this virus. The aim of this study was to investigate the outbreak of SARS-CoV-2 reinfections observed in mid-January 2022 in Rio Grande do Norte state, Brazil. It describes the clinical and genomic characteristics of nine cases of reinfection that occurred coincident with the introduction of the omicron variant. Methodology/Principal findings: Of a total of 172,965 individuals with upper respiratory symptoms tested for SARS-CoV-2, between March 2020 through mid-February 2022, 58,097 tested positive. Of those, 444 had documented a second SARS-CoV-2 infection and nine reinfection cases were selected for sequencing. Genomic analysis revealed that virus lineages diverged between primary infections and the reinfections, with the latter caused by the Omicron (BA.1) variant among individuals fully vaccinated against SARS-CoV-2. Conclusions/Significance: Our findings suggest that the Omicron variant is able to evade both natural and vaccine-induced immunity, since all nine cases had prior natural infection and, in addition, were fully vaccinated, emphasizing the need to develop effective blocking vaccines. Author summary: The pattern of the COVID-19 pandemic has been characterized by multiple surges of infection with a variety of outcomes. By December 2021, about 75.3% of the population of the state of Rio Grande do Norte in northeastern Brazil, had been fully vaccinated against SARS-CoV-2 and a decrease in case detection from a mean of 32% of positives to about 8% of cases tested. Nevertheless, with the introduction of the Omicron variant at the end of 2021, the number of new SARS-CoV-2 infections reached its highest peak, with 75% of the suspected cases testing positive. Among the positive cases diagnosed in the Institute of Tropical Medicine between March 2020 to mid-February 2022 a total of 444 reinfections were identified; of which 62.3% (n = 277) occurred during the Omicron outbreak. Of the reinfection cases, nine were sequenced as part of genomic surveillance. Analysis showed that the reinfections' lineages belonged to BA.1 introduced multiple times into the region; whereas, the isolates from the first infection belonged to different lineages. Thus, our data suggest that the Omicron variant evades immunity from natural infection from any other SARS-CoV-2 variants as well as from the available vaccines, indicating the need for development of effective blocking vaccines.

To investigate the associations of maternal excess weight before pregnancy with (1) weaning at 3 months of age, (2) duration of exclusive breast-feeding at 6 months of age, (3) duration of any breast-feeding at 12 months of age and (4) to compare the magnitude of these associations over four decades. Data were from participants in the Pelotas (Brazil) Birth Cohorts born in 1982 (n 5334), 1993 (n 1442), 2004 (n 4092) and 2015 (n 4102). Maternal pre-pregnancy weight was collected after the delivery and breast-feeding status was assessed when children were 3 and 12 months old. Only in the most recent cohort (2015), women with excess weight (BMI ≥ 25 kg/m2) before pregnancy had higher risk of discontinuing exclusive breast-feeding within the first 6 months postpartum than women with normal weight (hazard ratio = 1·22 (95 % CI 1·15, 1·30)). Duration of any type of breast-feeding until 12 months of age was not affected by pre-pregnancy weight. Excess weight before pregnancy is associated with exclusive breast-feeding only in the most recent birth cohort coinciding with increases in excess weight and breast-feeding over time.

Physical activity has been associated with enhanced mental health among adults. However, it is not clear in the literature which domains (occupational, transport and leisure-time exercise) and intensities (moderate, vigorous and moderate-to-vigorous) of activity provide the greatest benefits. The aim of the present study was to describe the association of different domains and intensities of physical activity with depressive symptoms in adults. This was a cross-sectional observational study conducted among 209 adults (≥18 years) in Brazil. Depressive symptoms were assessed using the HADS questionnaire (Hospital Anxiety and Depression Scale). Physical activity intensities (moderate, vigorous and moderate-to-vigorous) were device-measured by accelerometry. Physical activity in different domains (occupational, transport, and leisure-time exercise) was self-reported using a questionnaire. Chronological age, ethnicity, body mass index, highest academic achievement, employment status, alcohol consumption, tobacco smoking, chronic morbidity and soft-drink ingestion were adopted as adjustment confounding factors. Linear regression analysis revealed that total self-reported physical activity [β = –0.100 (95%CI: –0.180 to –0.019)] and leisure-time exercise [β = –0.311 (95%CI: –0.468 to –0.155)] were negatively associated with depressive symptoms, but only leisure-time exercise remained significant after adjustment for confounding factors [β = –0.243 (95%CI: –0.409 to –0.076)]. Thus, leisure-time exercise was cross-sectionally associated with lower depressive symptoms in community-dwelling adults. Leisure-time physical activity was the only physical activity domain associated with lower depressive symptoms. This association appears to be independent of potential confounders. Potential interventions should focus on leisure-time domain. [ABSTRACT FROM AUTHOR]

Background: Small mammals (rodents and marsupials) have been poorly explored for the occurrence of apicomplexan (genus Hepatozoon and genera of the order Piroplasmorida) and Anaplasmataceae agents in Brazil. Thus, this study investigated the occurrence of Hepatozoon spp., Piroplasmorida, and Anaplasmataceae agents in small mammals in seven forest fragments in Brazil. Methods: During 2015–2018, small mammals were captured in six forest fragments in the State of São Paulo (Cerrado and Atlantic Forest biomes) and one fragment in the State of Mato Grosso do Sul (Pantanal biome). Mammal blood, liver, spleen, and lung samples were tested molecularly for the presence of DNA of Hepatozoon, Piroplasmorida, and Anaplasmataceae agents. Results: A total of 524 mammals were captured, comprising seven species of marsupials, 14 rodents, two carnivores, and one Cingulata. Four novel haplotypes (1, 2, 3, 4) of Hepatozoon spp. were detected in small mammals from different biomes. In São Paulo state, haplotype 1 was detected in rodents from Cerrado and a transition area of Cerrado and Atlantic Forest biomes, whereas haplotype 2 was detected in rodents from the Atlantic Forest biome. On the other hand, haplotypes 3 and 4 were restricted to rodents and marsupials, respectively, from the Pantanal biome of Mato Grosso do Sul. No host species shared more than one haplotype. Despite these distinct geographical and host associations, our phylogenetic analyses indicated that the four Hepatozoon haplotypes belonged to the same clade that contained nearly all haplotypes previously reported on rodents and marsupials, in addition to several reptile-associated haplotypes from different parts of the world. No mammal samples yielded detectable DNA of Piroplasmorida agents. On the other hand, the Anaplasmataceae-targeted polymerase chain reaction (PCR) assay amplified a sequence 100% identical to the Wolbachia pipientis endosymbiont of the rodent filarid Litomosoides galizai. Conclusions: We report a variety of Hepatozoon haplotypes associated with small mammals in three Brazilian biomes: Cerrado, Atlantic Forest, and Pantanal. Through phylogenetic analyses, the Hepatozoon agents grouped in the rodent-marsupial-reptile large clade of Hepatozoon spp. from the world. The detection of a W. pipientis associated with the rodent filarid L. galizai indicates that the rodent was infected by filarial nematodes. [ABSTRACT FROM AUTHOR]

In this study we report the first case of an introduced alien host spider species being parasitized and manipulated by an ichneumonid wasp. Hymenoepimecis bicolor, previously described parasitizing exclusively Trichonephila clavipes (Araneidae), was observed parasitizing the European species Cyrtophora citricola (Araneidae) in southeastern Brazil. The cocoon web built by the parasitized spider is composed of a reduced horizontal sheet, which maintains the radial structure. The reduced number of radii and spirals probably reduce the chances of insect interception by these modified structures. In addition, the density of supporting threads is apparently very different between normal and modified webs. The cocoon web spun by C. citricola lacks the protective barrier structure usually observed in cocoon webs spun by parasitized females of T. clavipes. Our observations are in agreement with several predictions of the ecdysteroid hypothesis and represent an interesting opportunity for further investigation of interactions between these parasitoids and their spider hosts.

Purpose: To investigate the association of sedentary behavior and physical activity from childhood to adolescence with prevalence of low back pain in adolescents. In addition, we also explored whether sleep quality influences this association. Methods: This is a cross-sectional epidemiological study. Participants (aged 10–17 years) were recruited from public and private schools in Brazil. Sedentary behavior and previous and current engagement in physical activity were assessed through questionnaires. Low back pain and sleep quality were assessed by the Nordic questionnaire and Mini-Sleep Questionnaire, respectively. Sex, age, body mass index, abdominal obesity, socioeconomic status and sleep quality were used as potential confounders. Binary logistic regression models were used to generate values of odds ratio (OR) and 95% confidence intervals (95%CI). Results: A total of 1,001 (44,5% boys; n = 446) were included. Overall prevalence of low back pain was 18%, with higher rates among inactive and sedentary participants. Physical inactivity from childhood to adolescence in combination with high sedentary behavior doubled the likelihood of having low back pain (OR = 2.40 [95%CI: 1.38–4.18]), independent of potential confounders. Sleep quality attenuates, but not eliminates, this association (OR = 2.19 [95%CI: 1.25–3.84]). Conclusion: Being inactive from childhood to adolescence in combination with high sedentary behavior is associated with low back pain in adolescents. Sleep quality seems to attenuate, but not eliminate, this association. [ABSTRACT FROM AUTHOR]

The first autochthonous case of chikungunya virus (CHIKV) infection in Brazil was in September 2014 in the State of Amapá, and from there it rapidly spread across the country. The present study was conducted in 2016 in the state of Rio Grande do Norte, and the aims were to describe the epidemiological and the clinical aspects of the CHIKV outbreak. Biological samples from 284 chikungunya suspected cases were screened for CHIKV and Flavivirus (FV) RNA using qRT-PCR. Negative PCR samples were also screened for anti-CHIKV and anti-FVIgM by ELISA. CHIKV RNA were detected in 125 samples mostly occurring from January through March (46%), mainly affecting adults and older adults. We found a gradual decrease in viral RNA over the disease time. Anti-CHIKV IgM was found in 47.5% after negative CHIKV qRT-PCR. Interestingly, 45.0% simultaneously had positive results for CHIKV and FV IgM, suggesting the occurrence of virus co-circulation. The most frequent symptom was fever (91%). Women presented more chance to develop nausea and abdominal pain compared to men. Our data described and allows us to better understand the clinical and epidemiological aspects of the 2016 chikungunya outbreak in Rio Grande do Norte and can help in the early clinical diagnosis of the virus.

Borrelia burgdorferi sensu lato (Bbsl) spirochetes include the agents of Lyme borreliosis in temperate regions of the Northern Hemisphere, and merge their transmission cycles mainly with ticks of the Ixodes ricinus complex. Twenty genospecies compose Bbsl currently, and with the exception of Borrelia chilensis, and Borrelia garinii, all have been described only for North America, Europe, North Africa, and Asia. Here, we collected specimens of Ixodes paranaensis, a tick associated with swifts in a Brazilian natural park from the state of Minas Gerais, and performed a molecular characterization of 11 borrelial genes. Based on comparisons of inter and intraspecific genetic divergences, and Bayesian phylogenetic trees inferred for 16S rRNA, flaB, p66, and concatenated clpA, clpX, pepX, pyrG, recG, nifS rlpB, and uvrA genes, we demonstrate the occurrence of a new genospecies of Bbsl. "Candidatus Borrelia ibitipoquensis" Ip37 is closely related to Borrelia sp. Am501, and Borrelia valaisiana, a spirochete transmitted by ticks of the I. ricinus complex in Eurasia that uses birds as reservoirs. In a similar ecological scenario involving ticks and avian hosts, the migratory swift Streptoprocne biscutata is the sole-documented bird associated with I. paranaensis, and, although not assessed in this study, could correspond to the vertebrate reservoir of this newly described genospecies in Brazil. Pathogenic roles of "Ca. B. ibitipoquensis" are still unknown. However, its possible vector I. paranaensis is not an anthropophilic tick, so human infections would be unlikely to occur. Our finding enhances the knowledge on Bbsl in South America, highlights the occurrence of ecologically and genetically related genospecies with vastly separated geographical distributions, and calls for the attention to explore a barely known diversity of spirochetes of this group in the region.

This study analyzed the association of body size dissatisfaction with body mass index, dietary pattern, and physical activity in adolescents. A sample of 1074 participants between 10 and 17 years of age was recruited. Body size dissatisfaction was assessed with the silhouettes' scale. Dietary pattern, physical activity, and socioeconomic status were assessed with questionnaires. Body mass index was measured objectively. The prevalence of body size dissatisfaction was 77.0%, where 29.8% desired to increase body size and 47.2% desired to decrease body size. Adolescents who desired to increase body size were more likely to consume vegetables and sweets and less likely to be in the highest quartile of physical activity than satisfied adolescents. Adolescents who desired to reduce body size were more likely to report lower fruit and vegetable consumption than satisfied adolescents. Health actions aiming to reduce body dissatisfaction in adolescents should address improvement in dietary pattern and physical activity engagement, considering that desires to increase or decrease body size were differently associated in this study.

Birds are recognized hosts of ticks, especially for the immature stages which may harbor various species and strains of Rickettsia. To explore landscapes inhabited by birds and their ticks would expand the knowledge on host-parasite relationships and the rickettsiae. The aim of this paper was to record the diversity of ticks collected on wild birds and assess the phylogenetic position of a novel Rickettsia strain detected in immature ticks. Birds were captured in the Ibitipoca State Park, located in the Minas Gerais state, southeastern Brazil, as part of a long-term research project on the ecology of ticks, birds and Rickettsia. We found three tick species parasitizing birds: Amblyomma aureolatum (63 larvae, 10 nymphs), Haemaphysalis leporispalustris (28 larvae, seven nymphs) and Amblyomma romarioi (27 larvae). Among these, A. aureolatum was the most abundant species including 54% (73/135) of the collected ticks. New tick-host records were: A. romarioi on Turdus amaurochalinus and H. leporispalustris on Thamnophilus caerulescens, Saltator similis and Zonotrichia capensis. Of the 82 ticks tested for Rickettsia spp. by PCR, two larvae (2.5%) of A. romarioi were infected with 'Candidatus Rickettsia paranaensis', a novel putative Rickettsia species closely related to Rickettsia africae, Rickettsia sibirica and Rickettsia parkeri, as corroborated by our phylogenetic analysis. Finally, we present a list of all records of immature stages of H. leporispalustris on passerine birds in Brazil. [ABSTRACT FROM AUTHOR]

Background: Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, has been associated with the transmission by the tick Amblyomma sculptum, and one of its main hosts, the capybara (Hydrochoerus hydrochaeris). Methods: During 2015–2019, we captured capybaras and ticks in seven highly anthropic areas of São Paulo state (three endemic and four nonendemic for BSF) and in two natural areas of the Pantanal biome, all with established populations of capybaras. Results: The BSF-endemic areas were characterized by much higher tick burdens on both capybaras and in the environment, when compared to the BSF-nonendemic areas. Only two tick species (A. sculptum and Amblyomma dubitatum) were found in the anthropic areas; however, with a great predominance of A. sculptum (≈90% of all ticks) in the endemic areas, in contrast to a slight predominance of A. dubitatum (≈60%) in the nonendemic areas. Tick species richness was higher in the natural areas, where six species were found, albeit with a predominance of A. sculptum (≈95% of all ticks) and environmental tick burdens much lower than in the anthropic areas. The BSF-endemic areas were characterized by overgrowth populations of A. sculptum that were sustained chiefly by capybaras, and decreased populations of A. dubitatum. In contrast, the BSF-nonendemic areas with landscape similar to the endemic areas differed by having lower tick burdens and a slight predominance of A. dubitatum over A.sculptum, both sustained chiefly by capybaras. While multiple medium- to large-sized mammals have been incriminated as important hosts for A. sculptum in the natural areas, the capybara was the only important host for this tick in the anthropic areas. Conclusions: The uneven distribution of R. rickettsii infection among A. sculptum populations in highly anthropic areas of São Paulo state could be related to the tick population size and its proportion to sympatric A. dubitatum populations.

This study analyzed the associations between physical activity (PA) and motor proficiency (MP) to determine what level of moderate PA might help avoid low MP in 8-10-year-old Brazilian children. We assessed MP of 98 children using the Bruininks-Oseretsky Motor Proficiency, Second Edition Short Form (BOT-2 SF), and we assessed PA using the GT3X + accelerometer. We analyzed data using means, standard deviations, frequency distribution, spearman correlation coefficients, Mann--Whitney U test, and the Receiver Operating Characteristics curve. There was a difference between groups of children with adequate or better versus low MP in minutes/day of moderate PA (defined as 2,296-4,011 accelerometer counts/minute; U = 666.0, p = .045) such that those with less time engaged in moderate PA had lower MP scores than peers with adequate MP. There was also a positive correlation between moderate PA and the strength and agility MP domain (rs = .226; p = .025). In addition, minutes/day of moderate PA less than or equal to 142.56 minutes showed predictive capacity for low MP (area under the curve = 0.635; p = .027). Thus, objective measures of PA were able to predict low MP in 8-10-year-old Brazilian children, with an approximate guideline of about 2.5 hours per day of moderate PA needed to protect against low MP.

The trematodes belonging to the genus Platynosomum are biliary parasites of birds and mammals (domestic and wildlife) in tropical and subtropical areas of the globe. Despite several reports on platynosomosis in captive nonhuman primates, mainly in South America, the taxonomy of species of Platynosomum that infect these hosts remains confused, and it is not clear whether the species found in cats is the same that infects nonhuman primates. Because a detailed morphological study of Platynosomum from nonhuman primates is lacking, in this study we analyzed specimens of Platynosomum recovered from the biliary system of Callithrix penicillata kept in captivity in an animal facility. The helminths were submitted to morphological and morphometric analyses in a light microscope and measurements of 16 morphological traits were taken. A kernel density estimation (KDE) was used to estimate density distributions of the measurements obtained as well as the occurrence of overlap with the ranges of the measurements known to 2 other species of Platynosomum previously described from South American marmosets, Platynosomum amazonensis and Platynosomum marmoseti. A principal component analysis (PCA) was also performed in order to evaluate the position of each of the 3 species in the multivariate gradient of morphometric measurements. The occurrence of a growth gradient was also evaluated by analysis of correlation between the measurements. Besides a great morphological variability, all specimens obtained from marmosets in this study were identified as Platynosomum illiciens (Braun, 1901). In addition, the published ranges of the measurements of P. amazonensis and P. marmoseti were completely contained within the ranges found in this study as revealed by KDE. The PCA did not show the formation of groups, and the 3 species were distributed along a growth continuum, also corroborated by correlation analysis. Therefore, P. amazonensis and P. marmoseti are here synonymized with P. illiciens. The involvement of wildlife hosts to the epidemiology of feline platynosomosis and implications for its control are briefly discussed. [ABSTRACT FROM AUTHOR]

The aim of this study was to estimate the prevalence and correlates of blood pressure (BP) according to somatic maturation in Southern Brazilian adolescents. A total of 1321 adolescents participated in the study (732 girls), aged between 10 and 16 years, enrolled in public schools. The assessment of BP was performed using oscillometric equipment. Measurements of body weight, height, waist circumference, and skinfold thickness were performed. Somatic maturation was estimated by the age at peak height velocity. Behavioral and hereditary variables were obtained using a questionnaire. Early-maturing adolescents had the highest prevalence of high BP (28%; 95% confidence interval, 24.6-33.5) compared with other maturational groups (P=.003). In late-maturing adolescents, the variables associated with BP were paternal hypertension (systolic BP: β=4.9; diastolic BP: β=5.3) and early physical activity (systolic BP: β=-4.0; diastolic DBP: β=-3.6). In average-maturing adolescents, waist circumference (systolic BP: β=0.3), body mass index (diastolic BP: β=0.5), and mother's hypertension (diastolic BP: β=1.8) were positively related to BP. In early-maturing adolescents, only waist circumference (systolic BP: β=0.3; diastolic BP: β=0.3) was associated with BP. The authors conclude that the prevalence of high BP is greater in adolescents with early maturity and the outcome appears to be related to biological indicators in this group. On the other hand, in late-maturing adolescents, behavioral and hereditary variables are more related to BP. [ABSTRACT FROM AUTHOR]

The aim of this study was to analyze the relationship between physical activity (PA) and total body (BLM), leg (LLM) and arm lean mass (ALM) in menopausal women. Sixty two 62 menopausal women were included (61.2±7.6 years). Their practice of PA was assessed by Actigraph GT3X accelerometer, and is reported as minutes per week of light or moderate-vigorous PA, and total PA. The sample was dichotomized into two groups according to their weekly practice of PA moderate-vigorous; physically active (≥150 minutes) and insufficiently active (<150 minutes). Body composition measures were assessed by DXA and were reported as percentages. Comparisons between the groups of PA and total and segmentai lean body mass were performed by independent t test. Association between the tertile of BLM and the groups of PA were performed by chi-square test. Physically active women showed significantly higher mean values for BLM (52.8±5.4 vs 49.8±4.7; p=0.028) and LLM (17.1 ±2.2 vs 15.9±1.8; p=0.026), whereas the difference in the ALM was not significant. When the BLM was categorized into tertiles, it was significantly greater in physically active women (higher tertile=44.7%), compared with the insufficiently active women (higher tertile = 16.7%). Menopausal women who spent more minutes engaged in moderate-vigorous PA can showed higher BLM and LLM. [ABSTRACT FROM AUTHOR]

A new species of Horismenus Walker, H. liturgusae Hansson & Schoeninger (Hymenoptera: Eulophidae), is described from material reared from an ootheca of an unidentified mantid species of genus Liturgusa Saussure (Mantodea: Liturgusidae). The new species is compared to H. argus Hansson, a species it is very similar to. Horismenus liturgusae sp. n. is gregarious and 49 adult specimens developed in the ootheca. This is the first record of a Horismenus species parasitizing mantids, and the first record of a Horismenus species from an ootheca. [ABSTRACT FROM AUTHOR]

Background: The prevalence of child sexual abuse (CSA) in the population has been poorly described in developing countries. Population data on child sexual abuse in Brazil is very limited. This paper aims to estimate lifetime prevalence of child sexual abuse and associated factors in a representative sample of the population aged 14 and over in a city of southern Brazil. Methods: A two-stage sampling strategy was used and individuals were invited to respond to a confidential questionnaire in their households. CSA was defined as non-consensual oral-genital, genital-genital, genital-rectal, hand-genital, hand-rectal, or hand-breast contact/intercourse between ages 0 and 18. Associations between socio-demographic variables and CSA, before and after age 12, were estimated through multinomial regression. Results: Complete data were available for 1936 respondents from 1040 households. Prevalence of CSA among girls (5.6% 95%CI [4.8;7.5]) was higher than among boys (1.6% 95%CI [0.9;2.6]). Boys experienced CSA at younger ages than girls and 60% of all reported CSA happened before age 12. Physical abuse was frequently associated with CSA at younger (OR 5.6 95%CI [2.5;12.3]) and older (OR 9.4 95%CI [4.5;18.7]) ages. CSA after age 12 was associated with an increased number of sexual partners in the last 2 months. Conclusion: Results suggest that CSA takes place at young ages and is associated with physical violence, making it more likely to have serious health and developmental consequences. Except for gender, no other socio-demographic characteristic identified high-risk sub-populations. [ABSTRACT FROM AUTHOR]

Objective: To investigate the validity of the Brief Infant Sleep Questionnaire (BISQ), in assessing sleep quality in childhood.Methods: This was a validation study with children from the Pelotas 2015 Birth Cohort. BISQ was applied to mothers when their children were 3, 6, 12, and 24 months of age. The poor sleep indicators analysed, as defined by BISQ, were >3 wakings per night, nocturnal wakefulness >1 h and total sleep duration <9/24 h, compared to number of wakings per night and nocturnal and total sleep duration defined by actigraphy taken as the gold standard. The Actiwatch wGT3X-BT device was used by the child consecutively during five days at three and six months and for three days at 12 and 24 months. At each age the prevalence, sensitivity, specificity, accuracy, and positive (PPV) and negative predictive values (NPV) of each sleep indicator was calculated.Results: A total of 586 children were enrolled in the study. Nocturnal wakefulness >1 h was the most frequent indicator at all ages, with higher sensitivity (varying from 27.5% at six months to 54.8% at three) and lower specificity (53.4% at three months to 79.4% at six months), in comparison to the other sleep indicators. Specificity for >3 wakings and total sleep duration <9 h was greater than 85.0% at all the ages. Higher accuracies were observed for total sleep <9 h at 3 (85.6%), 6 (88.2%) and 12 months (73.6%) and for > 3 wakings at 24 months (84.5%). The sensitivity for the presence of at least one indicator decreased with age from 56.0% at three months to 35.8% at 24 months, whereas the specificity increased from 50.6% at three months to 63.8% at 24 months.Conclusion: The high specificity of the BISQ sleep parameters supports the validity of parents' reports on sleep-related problems in childhood for use in epidemiological studies.

During the revision of the southern South American species of Praxelis, populations of P. clematidea were found in northwestern Uruguay. In this study, we provide the first record of the genus and the species for the Uruguayan flora, along with taxonomic and morphological analyses based on herbarium specimens and field observations. In addition, uses of P. clematidea, its distribution and habitat, common names, an illustration and a key to differentiate the species of Praxelis of Uruguay and surrounding areas of Argentina and Brazil are presented.

Background: We utilised data from the 2015 Pelotas Birth Cohort, a large prospective cohort in southern Brazil, to examine the association of moderate and severe antenatal depression with child birth outcomes and explore interactions with sociodemographic characteristics.Methods: Data was available for n = 3046 participants and their infants. We measured antenatal depression using the Edinburgh Postnatal Depression Scale (EPDS, ≥13 for moderate and ≥17 for severe depression). Outcome measures included gestational age, birth weight, length and head circumference, using the Intergrowth-21st standards. We controlled for known confounders including obstetric risk.Results: We did not find differences in childbirth outcomes by maternal depression status for participants with at least moderate depression, although there was an increased risk for female offspring to be small for gestational age (SGA, OR 2.33[1.37,3.97]). For severe depression (EPDS≥17) we found an increased risk for lower APGAR scores (OR 1.63[1.02,2.60]) and being SGA (OR 1.77[1.06,2.97], with an increased risk for female offspring in particular to be in lower weight centiles (-10.71 [-16.83,-4.60]), to be SGA (OR 3.74[1.89, 7.44]) and in the lower 10th centile for length (OR 2.19[1.25,3.84]).Limitations: include the use of a maternal report questionnaire to ascertain depressive symptoms.Conclusions: In this recent large longitudinal cohort in Brazil we did not find independent effects of depression on adverse birth outcomes or interactions with sociodemographic characteristics. We found an increased risk of being SGA for female offspring of women with moderate and severe depression, in line with other research suggesting females may be more susceptible to antenatal disturbances.Funding: This work was supported by the Wellcome Trust, United Kingdom (095582), the Brazilian National Research Council (CNPq) and the Coordination for the Improvement of Higher Education Personnel (CAPES).

Background: Cardiac risk stratification is related to the risk of the occurrence of events induced by exercise. Despite the existence of several protocols to calculate risk stratification, studies indicating that there is similarity between these protocols are still unknown. Objective: To evaluate the agreement between the existing protocols on cardiac risk rating in cardiac patients. Method: The records of 50 patients from a cardiac rehabilitation program were analyzed, from which the following information was extracted: age, sex, weight, height, clinical diagnosis, medical history, risk factors, associated diseases, and the results from the most recent laboratory and complementary tests performed. This information was used for risk stratification of the patients in the protocols of the American College of Sports Medicine, the Brazilian Society of Cardiology, the American Heart Association, the protocol designed by Frederic J. Pashkow, the American Association of Cardiovascular and Pulmonary Rehabilitation, the Société Française de Cardiologie, and the Sociedad Española de Cardiología. Descriptive statistics were used to characterize the sample and the analysis of agreement between the protocols was calculated using the Kappa coefficient. Differences were considered with a significance level of 5%. Results: Of the 21 analyses of agreement, 12 were considered significant between the protocols used for risk classification, with nine classified as moderate and three as low. No agreements were classified as excellent. Different proportions were observed in each risk category, with significant differences between the protocols for all risk categories. Conclusion: The agreements between the protocols were considered low and moderate and the risk proportions differed between protocols. [ABSTRACT FROM AUTHOR]

Background: Evidence shows that lack of physical activity and sedentary time are associated with higher prevalence of low back pain (LBP)., Objective: To investigate the association between replacing sedentary time and light physical activity with a higher physical activity level with the prevalence of LBP., Methods: Two hundred and sixty-six individuals from a city in southeastern Brazil were recruited to this cross-sectional study. Sedentary behavior and physical activity level were evaluated using an ActiGraph GT3X tri-axial accelerometer during 7 days. The prevalence of LBP was assessed using the Nordic questionnaire. Isotemporal substitution using logistic regression analyses were performed to investigate the association between replacing an activity with another in the prevalence of LBP., Results: Replacing time spent in sedentary behavior with moderate physical activity slightly reduced the prevalence of LBP (odds ratio [OR]= 0.97; 95% CI: 0.95, 0.98). In addition, replacing time spent in light physical activity with moderate physical activity also slightly reduced the prevalence of LBP (OR= 0.97; 95% CI: 0.95, 0.98). There was no association for replacing sedentary time and light or moderate physical activity with vigorous physical activity on the prevalence of LBP., Conclusions: The results suggest a small protective effect for LBP when replacing time in sedentary activities or light physical activity with moderate physical activity., Competing Interests: Conflicts of interest The author declares no conflicts of interest., (Copyright © 2024 Associação Brasileira de Pesquisa e Pós-Graduação em Fisioterapia.

As it flows through the city of São Paulo, the Tietê River receives heavy discharges of industrial effluents and domestic sewage, resulting from the city's continuous urban expansion and the inadequacy of its sanitary sewage system. This study focused on an analysis of the efficiency of PGα21Ca and quaternary ammonium tannate, water purification products, based on coagulation-flocculation and sedimentation tests, followed by treatment with a hydrodynamic cavitation reactor associated with ozonation in the treatment of Tietê River water. The removal of turbidity, apparent color, and chemical oxygen demand (COD) were evaluated. Jar testing assays were conducted, and the best turbidity removal rates were obtained with a concentration of 300 mg L-1 for PGα21Ca and 150 mg L-1 for quaternary ammonium tannate. The coagulation-flocculation treatment removed approximately 93% of turbidity for both coagulants. After combining coagulation-flocculation with hydrodynamic cavitation with ozonation, the final COD removal rate applying PGα21Ca was 47.63% in 1 hour of reaction, while that of quaternary ammonium tannate was 40.13% in 2 hours of reaction. Although the results appear to indicate the superior performance of PGα21Ca, it should be noted that the treatment with quaternary ammonium tannate also provided good results in reducing turbidity, COD, and apparent color, using a smaller dose of this coagulant and that its use may be more advantageous from an environmental point of view, due to its natural composition.

Background and Objective: To compare high-sensitivity C-reactive protein (hsCRP) levels according to smoking status and physical activity (PA) changes in adults., Methods: The sample consisted of 6028 participants (4833 men) who underwent a voluntary routine health evaluation at the Preventive Medicine Center at the Hospital Israelita Albert Einstein, Sao Paulo, Brazil, from January 2007 to December 2013. Data were collected at baseline and follow-up (2.7±1.6 years). Plasma hsCRP (in mg/L) was analyzed in both moments. Smoking status was obtained through a self-reported questionnaire, being participants classified as non-smokers, once smokers (report smoking at baseline or follow-up), and persistently smokers (reported smoking at both baseline and follow-up). PA was assessed by questionnaire in both moments, being participants classified as persistently inactive, became inactive, became active, and persistently active. The Rank Analysis of Covariance was used to compare hsCRP follow-up values according to smoking and physical activity status., Results: Persistently smokers showed significantly higher median values of hsCRP at follow-up (1.3 mg/L, IQR:0.6-2.8) than once smokers (1.1 mg/L, IQR: 0.6-2.4) and non-smokers (1.0 mg/L, IQR: 0.5-2.2), even considering covariates (p<0.001). Persistently actives had lower levels of hsCRP at follow-up when compared to persistently inactive in the three smoking status groups (non-smokers p<0.001, once smokers p = 0.001, and persistently smokers p = 0.037)., Conclusion: Persistently active participants had lower hsCRP values at follow-up than those persistently inactive in all the smoking status groups. Regular practice of PA is an important strategy for facing low-grade inflammation, even among smokers., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Christofaro et al.

Objective: Longitudinal patterns of growth in early childhood are associated with health conditions throughout life. Knowledge of such patterns and the ability to predict them can lead to better prevention and improved health promotion in adulthood. However, growth analyses are characterized by significant variability, and pattern detection is affected by the method applied. Moreover, pattern labelling is typically performed based on ad hoc methods, such as visualizations or clinical experience. Here, we propose a novel pipeline using features extracted from growth trajectories using mathematical, statistical and machine-learning approaches to predict growth patterns and label them in a systematic and unequivocal manner., Methods: We extracted mathematical and clinical features from 9577 children growth trajectories embedded with machine-learning predictions of the growth patterns. We experimented with two sets of features (CAnonical Time-series Characteristics and trajectory features specific to growth), developmental periods and six machine-learning classifiers. Clinical experts provided labels for the detected patterns and decision rules were created to associate the features with the labelled patterns. The predictive capacity of the extracted features was validated on two heterogenous populations (The Applied Research Group for Kids and the 2004 Pelotas Birth Cohort, based in Canada and Brazil, respectively)., Results: Features predictive ability measured by accuracy and F1 score was ≥ 80% and ≥ 0.76 respectively in both cohorts. A small number of features (n = 74) was sufficient to distinguish between growth patterns in both cohorts. Slope, intercept of the trajectory, age at peak value, start value and change of the growth measure were among the top identified features., Conclusion: Growth features can be reliably used as predictors of growth patterns and provide an unbiased understanding of growth patterns. They can be used as tool to reduce the effort to repeat analysis and variability concerning anthropometric measures, time points and analytical methods, in the context of the same or similar populations., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

The peroxisome proliferator-activated receptor gamma ( PPARG ) gene encodes a transcription factor involved in the regulation of complex metabolic and inflammatory diseases. We investigated whether single nucleotide polymorphisms (SNPs) and haplotypes of the PPARG gene could contribute with susceptibility to develop periodontitis alone or together with type 2 diabetes mellitus (T2DM). Moreover, we evaluated the gene-phenotype association by assessing the subjects' biochemical and periodontal parameters, and the expression of PPARG and other immune response-related genes. We examined 345 subjects with a healthy periodontium and without T2DM, 349 subjects with moderate or severe periodontitis but without T2DM, and 202 subjects with moderate or severe periodontitis and T2DM. PPARG SNPs rs12495364, rs1801282, rs1373640, and rs1151999 were investigated. Multiple logistic regressions adjusted for age, sex, and smoking status showed that individuals carrying rs1151999-GG had a 64% lower chance of developing periodontitis together with T2DM. The CCGT haplotype increased the risk of developing periodontitis together with T2DM. The rs1151999-GG and rs12495364-TC were associated with reduced risk of obesity, periodontitis, elevated triglycerides, and elevated glycated hemoglobin, but there was no association with gene expression. Polymorphisms of the PPARG gene were associated with developing periodontitis together with T2DM, and with obesity, lipid, glycemic, and periodontal characteristics.

Physical activity has been linked to higher cardiac autonomic modulation. However, it is not clear in the literature which type of intensity of physical activity (sedentary, light, moderate, or vigorous) could be related to better cardiac autonomic modulation and whether this relationship is similar in men and women. The aim of this study was to analyze the relationship between cardiac autonomic modulation and the different intensities of physical activity in men and women. The sample included 100 men and 131 women. Cardiac autonomic modulation was obtained by heart rate variability (SDNN, RMSSD, LF un, HF un, SD1, and SD2). Time spent in different intensities (sedentary, light, moderate, and vigorous intensity physical activity) was measured using a waist-worn accelerometer for seven days. Linear regression was used to verify the relationship between physical activity and cardiac autonomic modulation, considering the adjustment for age, ethnicity, and socioeconomic level. Among men, a significant relationship of moderate intensity was observed with SDNN (β = 2.442; p  = 0.021) and SD2 (β = 2.936, p  = 0.028), and of vigorous intensity with SDNN (β = 12.826, p  = 0.028), RMSSD (β = 16.370, p  = 0.018), and SD1 (β = 12.344, p  = 0.025) indices. Among women, light-intensity physical activity was significantly related with LFnu (β =  .655, p  = 0.005) and HFnu (β =  -.590, p  = 0.010) . Moderate and v igorous physical activity was associated with better cardiac autonomic modulation in men. Light physical activity was associated with lower sympathetic modulation in women.

The management of colorectal cancer liver metastasis (CRLM) has become complex because of the increasing availability of medical, radiological, and surgical treatment options applied either alone or in combination. However, resection remains the only evidence-based curative therapy. These Brazilian Society of Surgical Oncology surgical standards are intended to guide clinicians in the decision-making process for modern surgical management of CRLM within a multidisciplinary team in an evidence-based framework, focusing on resectable disease., (© 2022 Wiley Periodicals LLC.)

We studied communities of small mammals and their ticks in endemic (E) and non-endemic (NE) areas for Brazilian spotted fever (BSF), aiming to infer if diversity parameters of parasites and hosts could be related to occurrence and prevalence of rickettsial infection, especially Rickettsia rickettsii. We compared E and NE areas in human-modified landscapes (HMLs) and natural areas (BIO) with no report of BSF cases. Composition and equitability were important components of diversity explaining differences among areas. The marsupial Didelphis albiventris was dominant in HMLs, but not in natural areas, and this opossum was the main host for the tick Amblyomma sculptum, principal vector of R. rickettsii, especially in E areas. Communities of ticks were dominated by A. sculptum, followed by Amblyomma dubitatum in E areas. In NE areas, this dominance was inverted, with more A. dubitatum than A. sculptum infesting small mammals, but the numbers of ticks were much lower than in E areas. Composition and abundance of ticks in natural areas were very dissimilar from HMLs, with the lowest tick burdens. Didelphis albiventris in E areas presented higher seroprevalence and endpoint titres against R. rickettsii than in other areas. At least three Rickettsia species, non-pathogenic to humans, were detected in natural areas (Rickettsia bellii, Rickettsia amblyommatis and 'Candidatus Rickettsia andeanae'), and only one non-pathogenic species in HMLs (R. bellii). Our results suggest that higher diversity of ticks, hosts and rickettsiae could be relevant factors in buffering the effect in BSF occurrence. Particularly for D. albiventris, its importance has to be quantified in further studies considering the epidemiological scenario of BSF., (Copyright © 2021 Elsevier GmbH. All rights reserved.)

In this work, 37 growth promoters were quantitatively determined in bovine urine using a QuEChERS approach with acetonitrile, NaCl, and MgSO 4 :PSA for sample extraction. The analytes were separated and detected by liquid chromatography coupled to hybrid high-resolution mass spectrometry. The method was validated in accordance with the Decision 657/2002/EC guidelines, in which recoveries fell within the range 84-113%, relative standard varied between 2 and 32%, and detection limit between 0.1 and 2.5 μg L -1 . An adequate performance was evidenced during a proficiency test evaluation, and the developed method has been applied to routine analysis of growth promoters in Brazil. A highlight is the easiness of sample extraction combined with a quantitative determination of forbidden drugs using high-resolution mass spectrometry, which enables retrospective analysis in a surveillance perspective.

Adequate health literacy is important for strong health outcomes during pregnancy, particularly among mothers with high risk of adverse outcomes related to pregnancy and childbirth. Understanding the health literacy of young pregnant women in low-income settings could support strategies to reduce adverse outcomes in this population. This exploratory study assessed the health literacy of young pregnant adolescents and young adults from a rural area in Northeast Brazil and associated factors such as socioeconomic conditions, adequacy of prenatal care, and social support from family and friends. In this cross-sectional study, 41 pregnant adolescents (13-18 years) and 45 pregnant adults (23-28 years) from the Rio Grande do Norte state, Brazil, were assessed regarding health literacy through the Short Assessment of Health Literacy for Portuguese-Speaking Adults (SAHLPA, score from 0-18, inadequate if <15). Income sufficiency, self-perceived school performance, compliance with recommendations for adequate prenatal care, and social support were also assessed. A linear regression analysis was conducted to evaluate the variables associated with the SAHLPA score. Ninety-five percent of the adolescents and 53.3% of the adults ( p < 0.001) presented inadequate health literacy. Adolescent age (β - 3.5, p < 0.001), poorer self-perceived school performance (β - 2.8, p < 0.001), and insufficient income for basic needs (β - 2.8, p = 0.014) were associated with worse SAHLPA scores. Adolescent mothers have higher rates of inadequate health literacy in this population. Policies are needed to improve access to health information for young populations from rural low-income areas.

Some Ichneumonidae wasps, including the genus Acrotaphus Townes, 1960 (Ephialtini: Pimplinae), induce behavioral modification in their spider hosts. Acrotaphus is a New World parasitoid wasp genus with 26 described species. This genus belongs to the Polysphincta genus group, which are ectoparasitoids of spiders of the Araneidae. In this study, we describe a new species (Acrotaphus wagnerianae sp. n.) found in the Brazilian Amazon. In addition, we discuss for the first time the behavioral modification of spiders of the Wagneriana genus (Araneidae) by wasps of the Polysphincta genus group.

Aim: The aim of this study was to analyze the association between longitudinal physical activity patterns (persistently inactive, became active, became inactive, and persistently active) and the incidence of Metabolic Syndrome (MS) among adults., Methods: Our cohort included 5766 adults (18-59y) undergoing repeated routine health screening examinations, with a mean follow-up period of three years. Only subjects without MS at baseline were included in the study. MS was defined according to the ATP III definition, including assessments of fasting blood samples for the collection of HDL-C, triglycerides and glucose, blood pressure, and waist circumference. Physical activity was estimated using the international physical activity questionnaire and four patterns were created (persistently active, became active, became inactive, and persistently inactive). Information on tobacco smoking and alcohol consumption (through structured validated questionnaires), age, interval between baseline and follow-up, anti-hypertensive drugs, statin, anti-diabetic drugs were used as covariates. Logistic regression was conducted., Results: The mean age of participants at baseline was 41.6 ± 7.9 years. We identified 1701 subjects who were active at both moments, 1246 who became active, 709 who became inactive, and 2210 who were inactive at both moments. Persistently inactive subjects presented a higher incidence of MS [10.4% (95%CI = 9.2-11.8%)]. In the adjusted logistic regression analyses, subjects that became active [OR = 0.55(95%CI = 0.40-0.74)] and persistently active [OR = 0.35(95%CI = 0.26-0.46)] were less likely to develop MS when compared with persistently inactive subjects., Conclusion: Persistently active subjects demonstrated the lowest likelihood of developing MS, while subjects who became active presented an attenuated risk., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier B.V.

Objective: To explore the associations between the eating habits of sons and daughters and the eating habits, sedentary behavior, and physical activity of their fathers and mothers., Design: A cross-sectional survey of adolescents., Setting: The 6 largest schools in Londrina, Brazil., Participants: A total of 842 adolescents, 842 mothers, and 842 fathers participated in this study., Main Outcomes Measures: Eating habits of adolescents and sedentary behavior, physical activity, and eating habits of their fathers and mothers, measured by questionnaire., Analysis: The associations were identified by binary logistic regression, adjusted by adolescent's age, family's socioeconomic status, parents' educational level, and the other parental behavior., Results: Independent of educational level and socioeconomic condition, mothers' eating behaviors seem to be more closely related to their adolescent children's eating behavior (vegetables, fruits, fried foods, soft drinks, and sweets [P = .001]) than fathers' behaviors (fried foods and sweets [P = .01], soft drinks [P = .001]). In addition, the behaviors of mothers were more associated to the behaviors of daughters than to the behaviors of sons (7 vs 5 associated behaviors), while behaviors of fathers were more associated with the behaviors of sons than to the behaviors of daughters (4 vs 2 associated behaviors). No associations were noted for sedentary and physical activity behavior and eating behaviors between adolescents and their parents., Conclusions and Implications: Many eating habits of adolescents were associated with eating habits of both fathers and mothers, emphasizing the importance of family-focused health promotion actions. Future research is needed incorporating into the analyses, among others, the nutritional statuses and the clustering of healthy and unhealthy behaviors of parents and their children., (Copyright © 2019 Society for Nutrition Education and Behavior.

Background: Over-the-counter analgesic use during pregnancy, particularly acetaminophen, may be associated with negative developmental outcomes in children., Objective: Estimate associations of prenatal and early-life exposure to acetaminophen in early childhood with cognitive, motor, and language skills in two birth cohorts., Methods: The American Project Viva cohort (1217 mother-child pairs enrolled 1999-2002) assessed cognition at approximately 3 years using the Peabody Picture Vocabulary Test and the Wide Range Achievement of Visual Motor Abilities (WRAVMA). The Brazilian 2015 Pelotas Birth Cohort (3818 mother-child pairs) assessed cognition at 2 years using the INTERGROWTH-21st Neurodevelopment Assessment. We used linear regression to estimate associations of acetaminophen use during pregnancy (Project Viva and Pelotas) and infancy (Project Viva) with children's cognitive scores adjusted for maternal age, pre-pregnancy body mass index, education, parity, race/ethnicity, smoking and alcohol use during pregnancy, depression during pregnancy, antibiotic and ibuprofen use during pregnancy, household income, and child's sex., Results: In Project Viva, exposure to acetaminophen in both the 1st and 2nd trimester of pregnancy was associated with lower WRAVMA drawing scores (β -1.51, 95% CI -2.92, -0.10). However, in Pelotas, exposure to acetaminophen in both the 1st and 2nd trimester of pregnancy was not associated with INTER-NDA motor scores (β 0.02; 95% CI -0.05, 0.09) and was associated with higher INTER-NDA total scores (β 0.08, 95% CI 0.01, 0.16). Other comparisons did not show evidence for any associations., Conclusions: Inconsistencies and lack of specificity of the findings did not clarify the research question considering that we still have a large variability and uncertainty to define the risk or safety in the use of acetaminophen related to cognition in early childhood. More studies using better exposure assessment and better confounding variables are needed to clarify these associations., (© 2020 John Wiley & Sons Ltd.)

Background: Hepatic metastases are a major cause of death in patients with colorectal cancer. A comprehensive assessment of the prognostic factors associated with long-term survival could improve patient selection for surgical approaches and decrease morbidity and futile locoregional treatments., Methods: We performed a retrospective analysis of patients who underwent hepatectomy for colorectal liver metastases at a single center from 2000 to 2012., Results: To identify factors associated with 5- and 10-year overall (OS) and disease-free survival (DFS), we analyzed 280 patients and 150 patients in the 5- and 10-year cohorts, respectively. Only seven relapses occurred after 5 years of follow-up, and no relapses occurred after 10 years. Multivariable analysis indicated that bilobar disease and extra-hepatic disease before hepatectomy were independent 5- and 10-year predictors of OS, and major postoperative complications predicted OS in the 5-year survival cohort only. Our analysis indicated that prognostic factors associated with DFS included some confounders and was therefore inconclusive., Conclusions: Taken together, our results suggest that the predictors of 5- and 10-year OS rates of colorectal cancer patients with hepatic metastases are similar, differing only by postoperative complications that influenced exclusively 5-year survival. Since no relapse occurred 10 years after hepatic resection, oncological remission is likely., (© 2020 Wiley Periodicals, Inc.)

Brazilian spotted fever (BSF), caused by the bacterium Rickettsia rickettsii, is transmitted to humans mainly by the tick Amblyomma sculptum in southeastern Brazil. In most BSF-endemic areas A. sculptum populations are sustained chiefly by capybaras (Hydrochoerus hydrochaeris), which are also the host of another tick species, Amblyomma dubitatum, not implicated in R. rickettsii transmission. Herein, we evaluated the effects of relative humidity (RH), temperature, and water immersion on the successful development of the engorged stages of A. dubitatum and compared them with recently published data under the same experimental conditions for A. sculptum. We showed that free-living developmental stages (engorged larvae, nymphs and females, and eggs) of A. dubitatum had higher survival rates when these stages were submerged in water for different periods of times (24-72 h). On the other hand, higher survival rates were observed for A. sculptum when ticks were incubated at lower RH values, 65 or 78 %, regardless of summer or winter mean temperatures. These results suggest that A. dubitatum is more adapted to humid habitats and seasonally flooding soils than A. sculptum, whereas this latter species should be more adapted than A. dubitatum to drier habitats. The implications of these results for the spatial distribution of A. dubitatum and A. sculptum, in relation to BSF epidemiology, are discussed., (Copyright © 2019 Elsevier GmbH.

Background: Teachers perform repetitive movements all day, which can cause pain in body regions. This article analyzes the association of pain with sleep quality in this population., Objective: The objective of the study was to analyze the relationship of musculoskeletal pain and sleep quality in teachers from public schools., Methods: The sample consisted of 242 teachers, selected in a random process. Musculoskeletal pain and sleep quality were evaluated by using a questionnaire. The association between sleep quality and musculoskeletal pain was evaluated using the chi-square test. The magnitude of the associations was verified by Binary Logistic Regression, adjusted by sex, age, BMI, and socioeconomic status., Results: Teachers with poor sleep quality presented higher body mass index (BMI) values when compared to teachers with good sleep quality (27.9 vs 26.0, p = 0.012). Teachers with poor sleep quality were approximately twice as likely to report thoracic pain (OR = 2.16[95% CI = 1.12-4.16]), wrist pain (OR = 3.28[95% CI = 1.18-9.07]), low back pain (OR = 3.09[95% CI = 1.29-7.41]), and ankle/foot pain (OR = 2.83[95% CI = 1.32-6.08])., Conclusions: Teachers with poor sleep quality were approximately twice as likely to present pain in several body parts. Our findings revealed that poor sleep quality was significantly associated with musculoskeletal pain in Brazilian teachers of public schools, regardless of confounding factors.

Although most childbirth care in Brazil is financed by the Brazilian Unified National Health System (SUS), there are out-of-pocket expenditures (private personal costs) involved in births. This study aims to compare maternal out-of-pocket expenditures in births of children from the Pelotas Birth Cohorts of 2004 and 2015. The study drew on information collected right after birth and at three months of age. The target variables include sociodemographic and economic data, private health plan coverage, and expenditures related to the birth. Values from 2004 were adjusted to 2015 by the general price index. There was an increase in private health plan coverage from 33.4% (95%CI: 31.9-34.9) to 45.1% (95%IC: 43.6-46.7) in the target period, directly associated with the families' socioeconomic status (p < 0.001). There was an increase in mean expenditures on hospitalization for the birth, from BRL 60.38 (SD = 288.66) to BRL 171.15 (SD = 957.07), and in additional medical expenditures, from BRL 191.60 (SD = 612.86) to BRL 1,424.80 (SD = 4,459.16) among mothers admitted to hospital under their private health plans (and there was no significant difference in these expenditures for mothers that opted for direct payment). There was an important increase in expenditures for childbirth care, especially among mothers admitted to hospital under private health plans.

Importance: Poor sleep during early childhood is associated with adverse outcomes, including obesity, cognitive impairment, and mental and behavioral disorders., Objective: To assess the efficacy of an educational intervention in the promotion of nighttime sleep duration., Design, Setting, and Participants: This single-blind, intent-to-treat randomized clinical trial included participants in Pelotas, Brazil, aged 3 months who were followed up until age 24 months. Eligibility criteria included healthy infants aged approximately 3 months who slept less than 15 hours per 24 hours. Infants were randomized to the intervention group or control group., Interventions: Information on sleep characteristics, improvements in the environment, establishment of a nighttime sleep routine, and waiting before attending nocturnal awakenings was delivered to mothers in the intervention group by trained home-visitors at baseline. The intervention group received a telephone call on the first and second day after the intervention and a home visit on the third day after the intervention. The intervention's content was reinforced at health care visits for ages 6 months and 12 months. Mothers allocated to the control group were counseled on the benefits of breastfeeding for the mother's and child's health and given written material with content on breastfeeding., Main Outcomes and Measures: Nighttime sleep duration was measured by interview and actigraphy at baseline and ages 6, 12, and 24 months and diaries at baseline and age 6 months. At ages 3 and 6 months, nighttime sleep self-regulation was calculated by subtracting nighttime sleep duration recorded by actigraphy from nighttime sleep duration recorded in the diaries and at ages 12 and 24 months by subtracting nighttime sleep duration recorded by actigraphy from nighttime sleep duration obtained by interview., Results: Among 1812 mother-infant dyads invited to participate, 798 met the inclusion criteria and 586 agreed to participate. The intervention group included 298 infants (154 [52.9%] boys), and the control group included 288 infants (164 [58.2%] boys). At age 6 months, mean (SD) nighttime sleep duration recorded in diaries was 9.80 (1.85) hours in the intervention group and 9.49 (2.07) hours in the control group, a difference of 19 minutes longer for the intervention group. At age 12 months, mean (SD) nighttime sleep duration based on the Brief Infant Sleep Questionnaire was 8.43 (1.35) hours in the intervention group and 8.52 (1.35) hours in the control group, a difference of 5 minutes shorter for the intervention group. At age 24 months, compared with information from the interview, actigraphy records showed that children in the intervention group stayed awake at night without signalizing for a mean (SD) of 0.52 (2.52) hours, whereas children in the control group stayed awake at night without signalizing for a mean (SD) of 0.23 (2.43) hours. There were no statistically significant difference between groups in any of the sleep parameters investigated., Conclusions and Relevance: This randomized clinical trial found that the educational intervention did not achieve longer nighttime sleep duration among infants in the intervention group., Trial Registration: ClinicalTrials.gov identifier: NCT02788630.

Background: Studies of healthcare service use during the pregnancy-postpartum cycle often rely on self-reported data. The reliability of self-reported information is often questioned as administrative data or medical records, such as antenatal care cards, are usually preferred. In this study, we measured the agreement of antenatal care indicators from self-reported information and antenatal care cards of pregnant women in the 2015 Pelotas Birth Cohort, Brazil., Methods: In a sample of 3923 mothers, indicator agreement strengths were estimated from Kappa and prevalence-and-bias-adjusted Kappa (PABAK) coefficients. Maternal characteristics associated with indicator agreements were assessed with heterogeneity chi-squared tests., Results: The self-reported questionnaire and the antenatal care card showed a moderate to high agreement in 10 of 21 (48%) antenatal care indicators that assessed care service use, clinical examination and diseases during pregnancy. Counseling indicators performed poorly. Self-reported information presented a higher frequency data and a higher sensitivity but slightly lower specificity when compared to the antenatal card. Factors associated with higher agreement between both data sources included lower maternal age, higher level of education, primiparous status, and being a recipient of health care in the public sector., Conclusions: Self-reported questionnaire and antenatal care cards provided substantially different information on indicator performance. Reliance on only one source of data to assess antenatal care quality may be questionable for some indicators. From a public health perspective, it is recommended that antenatal care programs use multiple data sources to estimate quality and effectiveness of health promotion and disease prevention in pregnant women and their offspring.

Recent studies have reported several larvae of an unidentified Amblyomma species on passerine birds in Atlantic rainforest fragments in southeastern Brazil. These larvae yielded a unique 16S rRNA haplotype designated as Amblyomma sp. haplotype Nazaré, which showed nucleotide identity levels of 91% to Amblyomma parkeri Fonseca & Aragão, 1952 and 88% to Amblyomma longirostre (Koch, 1844). Herein, we describe Amblyomma sp. haplotype Nazaré as a new species, Amblyomma romarioi n. sp. Martins, Luz & Labruna, through a formal description of the male and female adult stages. Amblyomma romarioi is morphologically and genetically most closely related to A. parkeri, A. longirostre and Amblyomma geayi Neumann, 1899. Among males, the rectangular basis capituli and rounded coxa I spurs separates A. romarioi from A. parkeri, A. longirostre, and A. geayi, which have basis capituli triangular or slightly hexagonal, and pointed coxa I spurs. Among females, the V-shaped genital aperture and coxa I rounded spurs of A. romarioi contrasts to the U-shaped genital aperture and coxa I pointed spurs in A. parkeri, A. longirostre, and A. geayi. Larvae of A. romarioi have been collected on 24 species of passerines. The few records of nymphs and adults were on the black-fronted titi monkey Callicebus nigrifrons (Spix, 1823). The current distribution of A. romarioi is restricted to the Brazilian Atlantic rainforest, southeastern Brazil, in areas with altitude between 363 and 1600 m, within the distribution of C. nigrifrons. We discuss ecological features of Amblyomma romarioi, comparatively to A. parkeri, A. longirostre and A. geayi. The present study increases the Brazilian tick fauna to 74 species., (Copyright © 2019 Elsevier GmbH. All rights reserved.)
