BackgroundAn argument often used to support the view that psychotic experiences (PEs) in general population samples are a valid phenotype for studying the aetiology of schizophrenia is that risk factors for schizophrenia show similar patterns of association with PEs. However, PEs often co-occur with depression, and no study has explicitly tested whether risk factors for schizophrenia are shared between PEs and depression, or are psychopathology specific, while jointly modelling both outcomes.MethodWe used data from 7030 subjects from a birth cohort study. Depression and PEs at age 18 years were assessed using self-report questionnaires and semi-structured interviews. We compared the extent to which risk factors for schizophrenia across sociodemographic, familial, neurodevelopmental, stress–adversity, emotional–behavioural and substance use domains showed different associations with PEs and depression within bivariate models that allowed for their correlation.ResultsMost of the exposures examined were associated, to a similar degree, with an increased risk of both outcomes. However, whereas female sex and family history of depression showed some discrimination as potential risk factors for depression and PEs, with stronger associations in the former, markers of abnormal neurodevelopment showed stronger associations with PEs.ConclusionsThe argument that PEs are valid markers for studying the aetiology of schizophrenia, made simply on the basis that they share risk factors in common, is not well supported. PEs seem to be a weak index of genetic and environmental risk for schizophrenia; however, studies disentangling aetiological pathways to PEs from those impacting upon co-morbid psychopathology might provide important insights into the aetiology of psychotic disorders.

Incisional hernia (IH) is a relatively common sequelae of sigmoidectomy for diverticulitis. The aim of this study was to investigate factors that may predict IH in diverticulitis patients. Two hundred and one diverticulitis patients undergoing sigmoidectomy between January 2002 and December 2012 were identified (mean follow-up 5.15 ± 2.33 years). Patients with wound infections were excluded. Thirteen patient-associated, three diverticular disease-related, and 17 operative variables were evaluated in patients with and without IH. Volumetric fat was measured on pre-operative CTs. Fischer's exact, χ2, and Mann–Whitney tests and multivariate regression analysis were used for statistics. Thirty-four (17%) patients had an IH. On multivariate analysis, wound packing (OR 3.4, P = 0.017), postoperative nonwound infection (OR 7.4, P = 0.014), and previous hernia (OR 3.6, P = 0.005) were as independent predictors of IH. Fifteen of 34 (44%) patients who developed a hernia had a history of prior hernia. Of 33 potential risk factors analyzed, including smoking, chronic obstructive pulmonary disease, and obesity, the only patient factor present preoperatively associated with increased risk of a postsigmoidectomy hernia after multivariate analysis was a history of a previous hernia. Preoperative identification of patients with a history of hernia offers the opportunity to employ measures to decrease the likelihood of IH.

BackgroundThe risk for psychotic disorders is increased for many ethnic minority groups and may develop in early childhood. This study investigated whether the prevalence of psychotic experiences (PE) with high impact is higher among ethnic minority youth compared to majority youth and examined the significance of these PE.MethodA school-based study assessed a large community sample of 1545 ethnic minority and majority children in The Netherlands (mean age 12.98 ± 1.81 years). The Dutch (n = 702, 45.4%), Moroccan-Dutch (n = 400, 25.9%) and Turkish-Dutch (n = 170, 11.0%) ethnic groups could be studied separately. Self-report questionnaires on PE, impact and cultural context were administered.ResultsPrevalence of PE with high impact was 3.1% in Dutch, 9.5% in Moroccan-Dutch and 7.1% in Turkish-Dutch youth. Compared to Dutch youth, odds ratios were 3.0 [95% confidence interval (CI) 1.7–5.1] for Moroccan-Dutch youth and 2.2 (95% CI 1.1–4.6) for Turkish-Dutch youth. Differences were not explained by cultural or religious differences.ConclusionsThe increased risk for psychotic disorders in ethnic minorities may already be detectable in childhood, since PE with high impact were more common among ethnic minority youth compared to majority youth. The additional measurement of impact of PE appears to be a valid approach to identify those children at risk to develop psychotic or other more common psychiatric disorders.

Abstract Background: Meningiomas are the most common primary central nervous system tumors. Risk factors including- obesity, height, history of allergy/atopy or autoimmune diseases, have been assessed with conflicting results. In this study, we reviewed the database of a large cohort of Israeli adolescents in order to assess potential risk factors for the development of meningiomas. Methods: This study analyzed a cohort of 2,035,915 Jewish men and women who underwent compulsory physical examination as part of screening for army drafting between the age of 16 to 19 from 1948 to 1991. Meningioma incidence was identified by linkage to the national cancer registry. Cox proportional hazard models were used to estimate the hazard ratios for meningioma according the several risk factors including sex, BMI, height, history of allergic and autoimmune disease. Results: Linkage of the adolescent military database with the Israeli cancer registry revealed 480 cases of meningioma. The median age at diagnosis of meningioma was 42.1 ± 9.4 (range 17.4–62.6). On univariate analysis, only gender (female) and height were significantly associated with the risk of meningioma for the whole study population (p<0.01 for both variables). When analyzed separately for gender- height was significant only for men. Spline analysis in the men group showed the minimum risk at a height of 1.62 meters and a statistically significant increase in the risk for meningioma at heights taller than 1.85 meters. BMI was not associated with an elevated risk of meningioma even when analyzed separately for gender. Past medical history including asthma, diabetes, and other atopic and autoimmune diseases were not found to be associated with the risk of meningioma. Conclusion: In this large population study, we found that sex and taller height in adolescent males was associated with an increased risk of meningioma.

Introduction:  We aimed to identify potential risk factors for intussusception (ISS) among children presenting to two pediatric hospitals in Egypt. Methodology: In this case-control study,  enrolled children < 3 years old with ISS (confirmed radiologically and/or surgically) were  matched by age and gender to controls admitted with acute non-abdominal surgical illnesses. Stool samples were collected and tested for various enteric bacteria, rotavirus, enteric adenoviruses (EA, 40 and 41) and astroviruses using commercially available ELISA diagnostic kits. Results: From December 2004 to May 2009, 158 cases and 425 matched controls were enrolled. A history of diarrhoea and cough over the preceding four weeks of interview were more common in cases than controls, respectively. Children with mothers who had secondary education and above were 2.2 times more likely to have ISS than those whose mothers had a lower level of education. In spite of the low detection rate of EA infection (regardless of diarrhoea history) and asymptomatic rotavirus infection, they were detected in higher frequencies in cases than controls; however, infection with astrovirus and bacterial pathogens did not appear to be associated with increased risk of ISS. Conclusions: History of diarrhoea and cough over the four weeks preceding the study and maternal education above secondary level were potential risk factors for ISS. EA and asymptomatic rotavirus infection were detected in higher frequencies among cases than controls; however, association with ISS cannot be confirmed. Additional research is needed to confirm these findings and evaluate the pathogenesis which may link such infections with ISS.

Aggression by cats towards humans is a serious behavioural, welfare and public health problem, although owners may believe it is an inevitable part of cat ownership. There has been little scientific investigation of the risk factors associated with this problem. One hundred and seven owners in the Sao Paulo region of Brazil, took part in a survey aimed at investigating the perceived prevalence of the problem, defining the most common contexts of human directed aggression and identifying associated potential risk factors. Human directed aggression occurred in 49.5% of cats and was most commonly associated with situations involving petting and play, followed by protection of a resource, when startled, when observing an unfamiliar animal and least commonly when unfamiliar people were present. Pedigree status, neuter status, a history of early trauma, sensitivity to being stroked, the absence of other cats in the home, relationship with other animals, level of background activity at home, access to the outside and tendency to be alone (meaning tendency to staying far from the family members) were all associated with an increased risk in one or more context. However, sex, age, age when acquired, source of pet, attachment to a specific household member, type of domestic accommodation, relationship with another cat if present and contact with other animals did not appear to increase the risk. The results suggest sensitivity to being stroked and background levels of stress in the home are the most pervasive risk factors, and future research should aim to investigate these factors further. These data are of relevance when advising owners about the risk and development of this problem.

Background Psychotic experiences are reported by 5–10% of young people, although only a minority persist and develop into psychotic disorders. It is unclear what characteristics differentiate those with transient psychotic experiences from those with persistent psychotic experiences that are more likely to be of clinical relevance. Aims To investigate how longitudinal profiles of psychotic experiences, created from assessments at three different time points, are influenced by early life and co-occurring factors. Method Using data from 8045 individuals from a birth cohort study, longitudinal profiles of psychotic experiences based on semi-structured interviews conducted at 12, 18 and 24 years were defined. Environmental, cognitive, psychopathological and genetic determinants of these profiles were investigated, along with concurrent changes in psychopathology and cognition. Results Following multiple imputations, the distribution of longitudinal profiles of psychotic experiences was none (65.7%), transient (24.1%), low-frequency persistent (8.4%) and high-frequency persistent (1.7%). Individuals with high-frequency persistent psychotic experiences were more likely to report traumatic experiences, other psychopathology, a more externalised locus of control, reduced emotional stability and conscientious personality traits in childhood, compared with those with transient psychotic experiences. These characteristics also differed between those who had any psychotic experiences and those who did not. Conclusions These findings indicate that the same risk factors are associated with incidence as with persistence of psychotic experiences. Thus, it might be that the severity of exposure, rather than the presence of specific disease-modifying factors, is most likely to determine whether psychotic experiences are transient or persist, and potentially develop into a clinical disorder over time.

OBJECTIVE: To evaluate potential risk factors and the incidence of bleeding following adenoidectomy or tonsillectomy, with or without adenoidectomy requiring surgical treatment under general anesthesia. STUDY DESIGN AND SETTING: Retrospective chart review of 15,218 patients who underwent surgery between January 1, 1988, and September 30, 2001, at our institution (St. Anna Hospital, Duisburg). RESULTS: A total of 229 patients experienced post-operative bleeding (1.5%). Patients of male gender and 70 years of age or older were significantly at risk for post-tonsillectomy hemorrhage. The incidence of bleeding increased with age. Of the bleeding episodes, 76% occurred on the day of surgery; immediate abscess-tonsillectomy was not associated with an increased risk of bleeding. CONCLUSIONS: Hemorrhage following tonsillectomy and adenoidectomy is rare and predominantly occurs early after surgery. Male patients, 70 years of age or older, infectious mononucleosis, and a history of recurrent tonsillitis were identified as risk factors for post-tonsillectomy hemorrhage. Delayed hemorrhage has the potential to be life-threatening.

A cross-sectional study evaluating potential risk factors for odontoclastic resorptive lesions (ORL) in feline teeth was conducted. Owners of 32 cats with ORL and 27 cats without ORL were interviewed regarding their respective cat's demographic characteristics, diet, and medical and dental histories. Four factors were identified as significantly associated with ORL using unconditional logistic regression. A history of dental disease (gingivitis, calculus, or periodontal disease; odds ratio [OR], 4.5); city residence (OR, 4.4); and being an exclusively indoor cat (OR, 4.5) were associated with an increased risk for ORL. Consumption of commercial treats (OR, 0.3) appeared protective for ORL.

Staphylococcus aureus (S. aureus) has long been recognized as an important human pathogen causing many severe diseases. It is also a part of human normal flora with its ecological niche in the human anterior nares. This study focused on screening S. aureus nasal carriage in community and its relationship to human physiological and pathological factors which have not been studied in Vietnam previously. Two hundred and five volunteers in Ho Chi Minh City from 18 to 35 and over 59 years old both male and female participated in the study. Result showed that the prevalence of S. aureus nasal carriage in southern Vietnamese community was relatively low, only 11.2% (23/205), much lower than that in other international reports on human S. aureus. In addition, nasal carriage of the older age group (> 59 years old, 13.7%) was higher than that of younger age (18-35 years old, 10.4%). Other potential risk factors such as gender, career, height, weight, history of antibiotic usage, daily nasal wash, use of nasal medication sprays, acne problems, smoking and nasal problems showed no significant impact on S. aureus carriage. The obtained S. aureus nasal isolates were all sensitive to vancomycin. Lincomycin and tetracycline had low resistance rate with 4.3 % and 17.4 %, respectively. However, the isolates showed particularly high rate of multidrug resistance (54.2%) In summary, our data provided researchers an overview on S. aureus nasal carriage and antibiotic susceptibility profile of the community- isolated S. aureus in Vietnam. This would serve as valuable information on assessing risk of community-acquired S. aureus infections.

Background. Some studies with inconclusive results have reported a link between sarcoidosis and an increased risk of pulmonary embolism (PE). This study aimed at assessing a possible correlation between potential risk factors and PE in sarcoidosis patients. Methods. A total of 256 sarcoidosis patients (84 males and 172 females; mean age at diagnosis 49 ± 13) were enrolled after giving written informed consent. Clinical evaluations, laboratory and radiology tests were performed to evaluate the presence of pulmonary embolism. Results. Fifteen sarcoidosis patients with PE (4 males and 11 females; mean age at diagnosis 50 ± 11), diagnosed by lung scintigraphy and 241 sarcoidosis patients without PE (80 males and 161 females; mean age at diagnosis 47 ± 13), were observed. There was a statistically significant increase of the presence of antiphospholipid antibodies in the sarcoidosis group with pulmonary embolism. There was no statistically significant difference between the two groups as to smoking habit, obesity or hereditary thrombophilia frequency (p > 0.05, respectively). Conclusions. This study demonstrates a significant correlation between the presence of antiphospholipid antibody positivity and the pulmonary embolism events in our sarcoidosis patients. Furthermore, we propose screening for these antibodies and monitoring, aimed at timely treatment.
