Abstract Toxoplasmosis is a parasitic disease, which is prevalent across the world and has a strong environmental component in its transmission chain. The present study determined the seroprevalence and factors related to Toxoplasma gondii infection among free-range chickens from an Atlantic Forest area in Northeastern Brazil. A total of 550 free-range chickens were tested for T. gondii antibodies usingthe indirect fluorescent antibody test (IFAT, cut-off point 1:16), and 269 (48.9%; 95% CI = 44.7-53.1%) were positive. Among the 61 properties 57 (93.4%) had at least one seropositive animal. The robust Poisson regression model showed that the variables/categories associated with the seroprevalence of T. gondii were: region of origin of the animals/urban area (prevalence ratio [PR] = 2.346; P<0.001), management system/use of cages (PR = 1.591; P = 0.019), presence of rodents/yes (PR = 1.295; P = 0.035), and the type of food/use of food scraps (PR = 1.603; P = 0.009). The high prevalence found suggest that this scenario demands careful management, mainly regarding the use of scraps of undercooked or raw food, adequate environmental hygiene and frequent rodentcontrol.

ABSTRACT: Leptospirosis is a worldwide zoonosis caused by the bacteria Leptospira spp. that affects humans, domestic and wild animals. The present work aimed to conduct a cross-sectional survey for leptospirosis in the canine population of the Brejo Paraibano microregion, semiarid of Northeastern Brazil. From May to October 2017, blood samples from 414 dogs were collected in the counties of Alagoa Grande (n=100), Areia (n=79), Bananeiras (n=72), Alagoa Nova (n=73), Serrraria (n=25), Pilões (n=25), Borborema (n=20) and Matinhas (n=20). The tutors of the sampled dogs answered an epidemiological questionnaire, obtaining information about the animals, owner, residence and breeding of the dogs. Subsequently, the serum samples were subjected to the microscopic agglutination test (MAT), using a collection of 23 serovar pathogenic antigens and using the 1:50 dilution as the cutoff point. Of the 414 dogs analyzed 52 were seroreactive, resulting in an apparent prevalence of 12.6% and a real prevalence of 12.2%. Seroreactive dogs were found in the eight counties. Dogs were reactive for the serogroups Icterohaemorrhagiae (76.9%), Autumnalis (13.55%), Pomona (3.8%), Grippotyphosa (3.8%) and Serjoe (1.9%) Antibody titers ranged from 50 to 800. The statistical analysis (robust Poisson regression) detected six factors associated with seropositivity, including the rainy season (prevalence ratio; PR=1.94, P=0.013), male dogs (PR=2.10, P=0.005), animals with age greater than five years (PR=4.21, P=0.012), consumption of untreated water (PR=1.87, P=0.043), free access of dogs to street (PR=2.15, P=0.011) and contact with wildlife (PR=3.54, P=0.050). The serogroup Icterohaemorrhagiae has a high zoonotic potential and was the most frequent in seropositive animals. The high real prevalence of Leptospira spp. in a transmission region of the semiarid region of Paraíba and the occurrence of seroreactive animals in all the counties suggest wide distribution of the infection and reinforce the need for preventive measures to avoid infection in pets and, consequently, to humans. The analysis of factors associated with the prevalence suggest greater manegment cares with the dogs.

Background: Evidence on the effects of dietary quality on the risk of postpartum depression in the Chinese population is limited. This study aimed to examine the association between dietary quality and postpartum depression in Chinses lactating women.Methods: A total of 939 participants from 10 cities were included in this analysis. A one-time 24-h dietary recall was used to obtain the data on food consumption and dietary quality was assessed based on Diet Balance Index. The Edinburgh postnatal depression scale was considered at a cutoff point of 10 to detect postpartum depression. Poisson regression models were used to explore the association of dietary quality with postpartum depression.Results: Depressed women tended to have a more inadequate intake of vegetables and have more insufficient food variety. The median (25th, 75th) of the overall high bound score (HBS), low bound score (LBS), and diet quality distance (DQD) was 9 (5, 14), 30 (25, 37), and 40 (34, 47), respectively. Compared with subjects with the lowest quartile of LBS, those with the highest quartile of LBS had a higher risk of postpartum depression [adjusted prevalence ratio (aPR), 1.08; 95% confidence interval (95% CI), 1.01, 1.15; P for trend, 0.043]. We also observed a significant association between DQD and postpartum depression (Q4 vs. Q1: aPR, 1.07; 95% CI: 1.00, 1.14; P for trend, 0.036).Conclusion: Poor dietary quality was associated with postpartum depression in Chinese lactating women.

Abstract The aim of this study was to determine the frequency and factors associated with Toxoplasma gondii in naturally infected equids in northeastern Brazil. Serum samples from 569 equids (528 horses, 8 mules and 33 donkeys) were subjected to the indirect fluorescent antibody test. Generalized linear models were used to evaluate associated factors. Among the 569 animals sampled, 118 (30.6%) living in rural areas and 14 (26.42%) in urban areas were seropositive (p>0.05). Seropositive animals were observed on 95% of the farms and in all the municipalities. Donkeys/mules as the host, presence of domestic cats and rats on the farm, ingestion of lagoon water and goat rearing remained in the final model as factors associated with infection. Preventive measures such as avoiding the presence of domestic cats close to rearing areas, pastures and sources of water for the animals should be adopted. The wide-ranging distribution of positive animals also indicated that infection in other domestic animals and in humans, through the contaminated environment, was possible. It should be highlighted that there was the possibility that donkeys and mules would continue to have detectable titers for longer, thus explaining the prevalence found. Further studies are needed to confirm this possibility.

Seroprevalence of the antibodies of Brucella canis and Brucella abortus in dogs was assessed using a cross-sectional survey in Anambra and Enugu States, Nigeria. A total of 123 Companion dogs made up of 65 clinic dogs, 34 slaughter dogs and 24 household dogs were screened. For B. abortus antibody assay, the collected serum was used for Rose Bengal plate test (RBPT), Serum agglutination test (SAT) and Solid Phase Immunoassay technique with Immunocomb® Canine Brucellosis Antibody Test Kit was used. Out of the 123 dogs screened, none was positive for Brucella abortus antibodies while 34 (27.7%) of the dogs screened were positive for B. canis antibodies. There was a significant association (P0.05) between infection and sex, the infection was significantly higher (P0.05) in female than male dogs. Prevalence was significantly higher (P0.05) in Exotic breeds than in mixed and local dog breeds. There was no association (P0.05) between infection and antibody titre levels in the different categories of dogs. However, there was significant association (P0.05) between the presence of Brucella canis antibodies and free roaming of dogs. This study provides the first serological evidence of B. canis infection in dogs in Enugu and Anambra States. This shows that B. canis is endemic in both states, underscoring the need for further studies. Female dogs, exotic breeds and freely roaming dogs are at a higher risk of Brucella infection in the study area; therefore, preventive and control measures are strongly recommended

Abstract A cross-sectional study was carried out on a sample of 379 horses to determine the seroprevalence of Neospora spp. in Jordan using the indirect fluorescent antibody test. Five variables, namely locality (n=10), climatic zone (n=4), age group (n=3), gender, and breed were tested as risk factors for Neospora–immunoglobulin (Ig)G seropositivity at four cutoff titers (1:50, 1:200, 1:400, and 1:800) using univariate and multivariate logistic regression analyses. A total of 122 (32%; 95% CI: 28, 37) sera samples had anti-Neospora–IgG at a cutoff titer of 1:50. Increased Neospora–IgG seropositivity was found in horses in three localities (Madaba, Zarka, and Petra) and was associated with the following variables: cool temperate climate; age >14 years; and female gender. Seropositivity was found among horses from Madaba at all cutoff titers, Zarka at titers >1:200, and Petra at titers <1:200. Cool temperate climate was associated with titers <1:400. Horses aged >14 years were found to be associated with seropositivity at titers ≥1:200. Female gender was associated with high seropositivity at >1:800.

Abstract Background Screening is defined as the identification of unrecognized disease in an apparently healthy population. Symptomatic individuals are recommended to contact a physician instead of participating in screening. However, in colorectal cancer (CRC) screening this approach may be problematic as abdominal symptoms are nonspecific. This study aimed at identifying the prevalence of self-reported abdominal symptoms among screening-eligible men and women aged 50–74 years. Methods This cross-sectional survey study included 11,537 individuals aged 50–74 years invited for CRC screening from 9 to 23 September 2019. Descriptive statistics of responders experiencing alarm symptoms of CRC, Low Anterior Resection Syndrome Score (LARS) and the Patient Assessment of Constipation-Symptoms (PAC-SYM) were derived. The association between abdominal symptoms and demographic and socioeconomic variables were estimated by prevalence ratio (PR) using a Poisson regression model with robust variance. Results A total of 5488 respondents were included. The respondents were more likely women, of older age, Danish, cohabiting and had higher education and income level compared to non-respondents. Abdominal pain more than once a week was experienced by 12.0% of the respondents. Of these, 70.8% had been experiencing this symptom for >1 month. Fresh blood in the stool was experienced by 0.7% and of these 82.1% for >1 month. About one third of those experiencing alarm symptoms more than once a week for >1 month had not consulted a doctor. A total of 64.1% of the respondents had no LARS, 21.7% had minor LARS and 14.2% had major LARS. The median PAC-SYM score was 0.33 (Interquartile range (IQR): 0.17;0.75), the median abdominal score was 0.50 (IQR: 0.00;1.00), median rectal score 0.00 (IQR:0.00;0.33) and median stool score 0.40 (IQR: 0.00;0.80). Men and those aged 65–74 reported less symptoms than women and those aged 50–64 years, respectively. Conclusions This study illustrated that abdominal symptoms were frequent among screening-eligible men and women. This should be taken into account when implementing and improving CRC screening strategies. A concerning high number of the respondents experiencing alarm symptoms had not consulted a doctor. This calls for attention to abdominal symptoms in general and how those with abdominal symptoms should participate in CRC screening.

AbstractImportanceEmerging evidence suggests many people have persistent symptoms after acute COVID-19 illness.ObjectiveTo estimate the prevalence and correlates of persistent COVID-19 symptoms 30 and 60 days post onset using a population-based sample.Design & SettingThe Michigan COVID-19 Recovery Surveillance Study is a population-based cross-sectional survey of a probability sample of adults with confirmed COVID-19 in the Michigan Disease Surveillance System (MDSS). Respondents completed a survey online or via telephone in English, Spanish, or Arabic between June - December 2020.ParticipantsLiving non-institutionalized adults (aged 18+) in MDSS with COVID-19 onset through mid-April 2020 were eligible for selection (n=28,000). Among 2,000 adults selected, 629 completed the survey. We excluded 79 cases during data collection due to ineligibility, 6 asymptomatic cases, 7 proxy reports, and 24 cases missing outcome data, resulting in a sample size of 593. The sample was predominantly female (56.1%), aged 45 and older (68.2%), and Non-Hispanic White (46.3%) or Black (34.8%).ExposuresDemographic (age, sex, race/ethnicity, and annual household income) and clinical factors (smoking status, body mass index, diagnosed comorbidities, and illness severity).Main outcomes and MeasuresWe defined post-acute sequelae of SARS-CoV-2 infection (PASC) as persistent symptoms 30+ days (30-day COVID-19) or 60+ days (60-day COVID-19) post COVID-19 onset.Results30- and 60-day COVID-19 were highly prevalent (52.5% and 35.0%), even among respondents reporting mild symptoms (29.2% and 24.5%) and non-hospitalized respondents (43.7% and 26.9%, respectively). Low income was statistically significantly associated with 30-day COVID-19 in adjusted models. Respondents reporting very severe (vs. mild) symptoms had 2.25 times higher prevalence of 30-day COVID-19 (Adjusted Prevalence Ratio [aPR] 2.25, 95% CI 1.46-3.46) and 1.71 times higher prevalence of 60-day COVID-19 (aPR 1.71, 95% 1.02-2.88). Hospitalized (vs. non-hospitalized) respondents had about 40% higher prevalence of both 30-day (aPR 1.37, 95% CI 1.12-1.69) and 60-day COVID-19 (aPR 1.40, 95% CI 1.02-1.93).Conclusions and RelevancePASC is highly prevalent among cases with severe initial symptoms, and, to a lesser extent, cases with mild and moderate symptoms.

OBJECTIVE: To explore the association of occupational pesticide exposure with acute and mental health symptoms. METHODS: Cross-sectional survey carried out with 78 Brazilian family farmers, who were pesticide applicators and helpers conveniently selected. Symptoms and exposure data were collected by interviews, and mental health outcomes by the Self-Reporting Questionnaire. Blood samples were analyzed to assess cholinesterase levels. Exposure indicators and symptoms were compared between applicators and helpers, and Poisson regression was performed to estimate prevalence ratios. RESULTS: Farmers reported exposure to multiple pesticides from early ages; they worked without safety training, technical support, and full protective equipment, and they had a high prevalence of acute and mental health symptoms (e.g., headache, mucosal irritation, tachycardia, and depressive signs). Applicators had more cholinesterase changes than helpers, but less symptoms. Helpers used less personal protection and had significantly higher prevalence ratio of headache, dyspnea, wheezing, cough, poor digestion, tiredness, and feeling worthless, after adjustment. CONCLUSIONS: Acute and mental health symptoms were observed, both among farmers and helpers. Thus, surveillance actions must be reinforced in Brazil, technical support and safety training improved, focused on applicators and helpers, who are occupationally and environmentally exposed to pesticides. Agricultural practices of these groups with less pesticide use should receive incentive.

Abstract Background: There is little information about the frequency of Leishmaniainfection in asymptomatic HIV infected individuals and about the performance of laboratory diagnostic methods in coinfected patients in Latin America. The main objective of this study is to evaluate the frequency of Leishmaniaspp. infection in HIV infected patients living in an urban area from Brazil. Methods: To detect Leishmaniainfection, were performed diagnostic tests to detection of antibodies anti-Leishmania(ELISA using Leptomonas seymouriantigens; ELISA using rk39 antigens; ELISA using rK28 antigens; indirect fluorescent-antibody test (IFAT); direct agglutination test (DAT) and detection of LeishmaniaDNA by polymerase chain reaction (PCR) with the target genes kDNA and ITS-1. Results: Frequency, considering at least one positive test, was 15%. For ELISA using Leptomonasantigens and IFAT, there was an association between CD4+ T-lymphocyte counts and test positivity, with a higher positivity of these tests in more immunosuppressed patients (T CD4+ cells count < 200/mm3). Conclusions: According to our data, there was a high prevalence of Leishmaniaspp. in this population living with HIV. Although there is the possibility of cross-reaction, some tests considered highly specific for the diagnosis of Leishmania infection were positive. There was also an association between the positivity of some tests studied and lower values of T CD4+ lymphocytes.
