Aims: Giardia duodenalis is a globally distributed zoonotic protozoan. It has a variable prevalence. This study determines the prevalence of Giardia spp. in cat faecal samples from states of the Mexican Republic. Place and Duration of Study: Was carried out in 23 of the 32 states of the Mexican Republic, from June to December 2019.  Methodology: Stool samples from 1591 client-owned cats were analysed for the detection of G. duodenalis (cysts or trophozoites). Faecal samples were analysed by direct smear techniques with and without staining (Lugol) and centrifugal floatation (faust), and were examined under a light microscope.  Results: Of the cats sampled, 56.94% were positive for G. duodenalis. Its prevalence was associated and is a risk factor in cats that live with other animals (Chi2= 21.84, p= 0.0001; OR= 1.61, p= 0.0001), with hunting habits (Chi2= 5.53 p= 0.01, OR= 1.27 p= 0.01), with access to the outside (Chi2= 53.06, p= 0.0001; OR= 2.13, p=0.0001) and with the aqueous faeces (Chi2= 12.30, p=0.03; Chi2= 1.71, p= 0.03). Factors for not presenting Giardia spp. in faeces were, not brushing the cat (OR=0.74, p= 0.006), provenance (OR= 0.42, p=0.02), and median height (OR= 0.78, p= 0.01). Age, gender, hair type, coexistence with other cats and other stool findings were not associated as risk factors for infection. Conclusion: This study demonstrated a high overall prevalence of G. duodenalis in cats in Mexico, in addition to an association of its prevalence with risk factors such as cats living with other animals, hunting habits and access to outdoors.

Diarrhoea is the second leading cause of infectious mor­bidity and mortality in children under five years of age. This study aimed at identifying the most common parasites and potential risk factors for diarrhoea among children 0-5 years attending Abia State Specialist hospital and Federal Medical Centre, Umuahia, in south east­ern Nigeria. We used 400 faecal samples from children with diarrhoea –and 200 without– in combination with hospital-based case control and a questionnaire Stool samples were processed with direct normal saline and formal-ether sedimentation method for parasitological stud­ies. More males than females were infected in nearly all age groups in both diarrhoeal and control groups (X2=23.04, df=1, P<0.05: X2=11.52, df=1, P<0.05 respectively). Amachara had more infections (X2=0.15, df=1, P< 0.05). January had the highest rate of infection (22.5%). Main clinical features were watery depositions over 3 times a day, diarrhoea lasting for days, fever, vomiting, and dehydration. Mothers learned about the problem through health workers, television and in medical centers. Risk correlated with mother’s education, occupation, latrine type, waste water disposal, hand washing, kitchen cleaning; sources and storage of water; and bottle milk (P< 0.05).Ignorance greatly con­tributed to the spread of parasitic disease in the area: the government should improve education and other strategies to alleviate the spread of the disease..

Abstract Gastrointestinal parasites are involved in the health and wellbeing of cats and some of them, due to their zoonotic character represent a problem for the public health. This study aimed to assess the prevalence of parasitic infections in cats with digestive symptoms. Faecal samples collected from 137 cats were analysed by the flotation method using sodium chloride saturated solution. The overall prevalence of gastrointestinal (GI) parasites was 56.6%. GI parasites were significantly (p=0.005) more common in cats with digestive symptoms (69.8%) than in clinically healthy ones (23.0%). Toxocara cati (40.2%) was the most frequently identified GI parasite, followed by Cystoisospora spp. (10.2%), Ancylostoma tubaeforme (3.7%), Taenia spp. (2.2), Giardia duodenalis (2.2%), and Toxoplasma gondii-like oocysts (0.7%). T. cati (53.3%, p<0.0001) and Cystoisospora spp. (15.6%, p<0.001) were significantly more frequently diagnosed in cats with digestive symptoms. Lack of deworming in the last three months (OR: 15.9), outdoor access (OR: 13.8), the presence of digestive symptoms (OR: 5.4), and young age (OR: 4.2) were identified as risk factors for T. cati infection by logistic regression analysis. Regardless of the age, symptoms like vomiting, diarrhoea, and inappetence were positively associated with T. cati.

Campylobacter Spp

To improve the understanding of implications of Campylobacterspp. infections in pets and children of different environments were analysed 160 faecal samples from children and 120 from pets (103 dogs and 17 cats). Campylobacter spp. were detected in 6.87% of the children and in 18.3% of the dogs and cats. From 33 stool samples positive for Campylobacter spp., 57.6% were identified as C. jejuni, and 33.4% were identified as C. coli. More than 50% of the isolates in pets were resistant to ceftiofur, sulphazotrim, norfloxacin and tetracycline. In humans, most of the isolates were resistant to amoxicillin, cefazolin, ceftiofur, erythromycin and norfloxacin. From 19 isolates of C. jejuni, 11 isolates from children and 5 from dogs contained two to four of the virulence genes flaA, pldA, cadF or ciaB.We found an association between the presence of virulence genes and diarrhoea. Furthermore, an association was observed between the presence of Campylobacter spp. and diarrhoea in dewormed pets with blood picture suggestive of bacterial infection, and the therapeutic use of antibiotics was associated with more positive detection of Campylobacterspp. in the faeces of pets. Our data indicate that virulent strains of Campylobacter spp. can be risk factor to diarrhoea in animals, and that high resistance to antimicrobial agents is common in pets.

Faecal Consistency

Objectives The aim of the study was to describe faecal consistency, prevalence and risk factors for diarrhoea and constipation in a rescue cat population. Methods Faecal samples in litter trays from a stratified random sample of cats in pens at 25 UK rehoming centres were scored for consistency in two discrete time periods, summer and winter. A six-point scale was used, with diarrhoea ⩽3, severe diarrhoea ⩽2 and constipation as 6. The effect on faecal consistency of age, number of cats per pen and season was investigated using multivariable hierarchical logistic regression with centre and pen as random effects. Intraclass correlation coefficients were used to estimate the effect of pen and centre. Results Overall, 11.9% (95% confidence interval [CI]:10.4–13.7) of cats had diarrhoea, 2.4% (95% CI 1.6–3.7) had severe diarrhoea and 5.6% (95% CI 4.2–7.5) were constipated. The prevalence of diarrhoea (median 11.0%, interquartile range [IQR] 5.0–14.5%) and constipation (median 4.2%, IQR 1.8–5.9) varied at the centre level. Diarrhoea was associated with being a kitten (odds ratio [OR] 2.54, 95% CI 1.45–4.46; P = 0.001) and being in a multi-cat pen (OR 1.24, 95% CI 1.04–1.48; P = 0.02) but not with season (OR 0.99, 95% CI 0.55–1.77; P = 0.96). Severe diarrhoea was associated with senior cats (OR 4.66, 95% CI 1.25–17.44; P = 0.02). Constipation was associated with increasing age (OR 1.01; 95% CI 1.00–1.01; P = 0.02) and winter (OR 0.43, 95% CI 0.21–0.89; P = 0.02). Both diarrhoea and constipation showed moderate correlation with pens within a centre. Conclusions and relevance From IQRs, we suggest acceptable levels for diarrhoea and constipation of 11% and 4%, respectively, targets of 5% and 2%, and intervention at 15% and 6%. Increasing age was associated with decreased risk of diarrhoea and increased risk of constipation. However, severe diarrhoea was associated with being a senior cat. Season (winter) was a risk factor for constipation; multi-cat pens were a risk factor for diarrhoea. Describing the prevalence and risk factors for diarrhoea and constipation in cats will assist their management in this population. Understanding and managing constipation may be more important than interventions to reduce severe diarrhoea.

The objective of the present study was to characterize Giardia duodenalis infection among children living in sub-standard settlement areas in the municipality of Juiz de Fora, Minas Gerais State, Brazil. The cross-sectional epidemiological study included 590 children from 1 to 5 years of age. Data were collected from one child per selected family through home interviews with the parent or guardian and parasitological examination of stool samples. Thirty-one putative risk factors concerning family structure, socioeconomic status, and environmental factors were analyzed by multivariate logistic regression. Prevalence of G. duodenalis infection was 18% (106 children). Four potential risk factors were heavily associated with G. duodenalis infection: number of under-five children in the same household, index child's birth order, existence of a bathroom in the home, and drinking water source.

SummaryThe retrospective observational study surveys the relationship between development of inhibitors in the treatment of haemophilia patients and risk factors such as changing FVIII products. A total of 119 patients were included in this study, 198 changes of FVIII products were evaluated. Results: During the observation period of 12 months none of the patients developed an inhibitor, which was temporally associated with a change of FVIII products. A frequent change of FVIII products didn’t lead to an increase in inhibitor risk. The change between plasmatic and recombinant preparations could not be confirmed as a risk factor. Furthermore, no correlation between treatment regimens, severity, patient age and comorbidities of the patients could be found.

Return Difference

AbstractStructured products like collateralized loan obligations (CLOs) tend to offer significantly higher yield spreads than corporate bonds (CBs) with the same rating. At the same time, empirical evidence does not indicate that this higher yield is reduced by higher default losses of CLOs. The evidence thus suggests that CLOs offer higher expected returns compared to CB with similar credit risk. This study aims to analyze whether this return difference is captured by asset pricing factors. We show that market risk is the predominant risk factor for both CBs and CLOs. CLO investors, however, additionally demand a premium for their risk exposure towards systemic risk. This premium is inversely related to the rating class of the CLO.

Chd Risk Factors

Cardiovascular disease, and particularly coronary heart disease (CHD), has a low incidence in premenopausal women. Loss of ovarian hormones during the perimenopause and menopause leads to a sharp increase in incidence. Although most CHD risk factors are common to both men and women, the menopause is a unique additional risk factor for women. Sex steroids have profound effects on many CHD risk factors. Their loss leads to adverse changes in lipids and lipoproteins, with increases being seen in low density lipoprotein (LDL) cholesterol and triglycerides, and decreases in high density lipoprotein (HDL) cholesterol. There is a reduction in insulin secretion and elimination, but increases in insulin resistance eventually result in increasing circulating insulin levels. There are changes in body fat distribution with accumulation in central and visceral fat which links to the other adverse metabolic changes. There is an increase in the incidence of hypertension and of type 2 diabetes mellitus, both major risk factors for CHD. Oestrogens have potent effects on blood vessels and their loss leads to dysfunction of the vascular endothelium. All of these changes result from loss of ovarian function contributing to the increased development of CHD. Risk factor assessment in perimenopausal women is recommended, thereby permitting the timely introduction of lifestyle, hormonal and therapeutic interventions to modify or reverse these adverse changes.

Health Education And Promotion

In health education and promotion, “risk factors” for disease gathered from epidemiological research form the basis from which the majority of recommendations to individuals for lifestyle change are made. Unfortunately, many health practitioners are unaware that this type of research was never intended to be applied to individuals. The result is ongoing public confusion and anxiety concerning health recommendations and a loss of credibility for health professionals. This article: 1) briefly reviews the most commonly encountered limitations inherent in epidemiological research; 2) explores the problems and potential negative consequences of incorrectly applying epidemiological research in health education and promotion; and 3) makes recommendations to help health practitioners more skillfully interpret and incorporate into their work findings from epidemiological research.
