BackgroundCampylobacter is the main pathogen involved in zoonotic gastrointestinal diseases. In 2018, European Regulation 2017/1495 on Campylobacter in broiler carcases came into force. In this context, the aim of the study was to assess the potential risk factors associated with exceeding the 1000 cfu/g (colony-forming units per gram) limit set by the EC in several slaughterhouses in Spain.MethodsData relating to 12 factors were collected using questionnaires. Samples were collected from 12 Spanish abattoirs in June, July and August 2017 (n=1725) and were analysed following the ISO 10272-2:2006 method.ResultsThe proportion of Campylobacter-positive samples was 23.7 per cent (n=409). Analysis of flock age (41–50 days) revealed a significantly increased odds ratio (OR) in Campylobacter enumeration (OR=7.41). Moreover, scalding temperature (51.9°C–54°C) was positively associated with an increase in OR (OR=2.75). Time in transit to slaughter for 1–1.5 hours showed a significant decrease in OR (OR=0.25), while time in transit for more than two hours showed an increase in OR (OR=4.44). With regard to carcase weight, a weight of 3.21–3.58 kg showed a decrease in OR (OR=0.01).ConclusionThe outcomes of this study suggest that although most chickens are contaminated by the bacterium, the prevalence of those exceeding the 1000 cfu/g limit is not so high as thought.

SUMMARYDuring 2007–2009 a UK-wide, 3-year stratified randomized survey of UK chicken broiler flocks was conducted to estimate the prevalence ofCampylobacter-infected batches of birds at slaughter. Thirty-seven abattoirs, processing 88·3% of the total UK slaughter throughput, were recruited at the beginning of the survey. Of the 1174 slaughter batches sampled, 79·2% were found to be colonized withCampylobacter, the majority of isolates beingC. jejuni. Previous partial depopulation of the flock [odds ratio (OR) 5·21], slaughter in the summer months (categorized as June, July and August; OR 14·27) or autumn months (categorized as September, October and November; OR 1·70) increasing bird age (40–41 days, OR 3·18; 42–45 days, OR 3·56; ⩾46 days, OR 13·43) and higher recent mortality level in the flock (1·00–1·49% mortality, OR 1·57; ⩾1·49% mortality, OR 2·74) were all identified as significant risk factors forCampylobactercolonization of the birds at slaughter. Time in transit to the slaughterhouse of more than 2·5 h was identified as a protective factor (OR 0·52).

Infantile anaemia has been a severe public health problem in China for decades. However, it is unclear whether there are regional differences in the prevalence of anaemia. In this study, we used data from the China Nutrition and Health Surveillance (CNHS) to assess the prevalence of anaemia and the risk factors associated with its prevalence in different regions. We included 9596 infants aged 0–23 months from the CNHS 2013 database. An infant was diagnosed with anaemia if he/she had a haemoglobin concentration of <110 g/L. We used multivariate logistic regression to investigate the potential risk factors associated with the development of anaemia. We found that anaemia was present in 2126 (22.15%) of the infants assessed. Approximately 95% of these cases were classified as mild anaemia. Based on the guidelines laid out by the World Health Organization, 5.5% and 43.6% of the surveillance sites were categorized as having severe and moderate epidemic levels of anaemia, respectively. The prevalence of infantile anaemia in Eastern, Central and Western China was 16.67%, 22.25% and 27.44%, respectively. Premature birth, low birth weight, breastfeeding and residence in Western China were significantly associated with higher odds of developing anaemia. Female sex and having mothers with high levels of education and maternal birth age >25 years were associated with lower odds of developing anaemia. In conclusion, we observed significant regional disparities in the prevalence of infantile anaemia in China. Western China had the highest prevalence of infantile anaemia, and rural regions showed a higher prevalence of anaemia than urban regions.

AbstractCervical insufficiency (CI) is a mainly disease leading to recurrent abortions and preterm birth which may present in about 1% of obstetric populations. Recurrent pregnancy losses caused by CI incur serious economic burdens on society as well as huge psychological burdens to family members. However, many patients even clinicians in some areas of the world still remain confused about this disease. At the same time, the etiology of CI is still uncertain and it is still a controversial disease in diagnosis and treatment. This article summarizes the potential risk factors associated with CI, which could be worthy of attention and helpful for future research. It also reviews the methods for diagnosis and treatment of CI to better understand this noteworthy disease, as well as presents the related consensus and controversies according to the newly updated guidelines, which has practical significance for conducting more in-depth investigations in the future.

Background: Hypotensive bradycardic events (HBEs) are a frequent adverse event in patients who underwent shoulder arthroscopic surgery under interscalene block (ISB) in the sitting position. This retrospective study was conducted to investigate the independent risk factors of HBEs in shoulder arthroscopic surgery under ISB in the sitting position. Methods: A total of 2549 patients who underwent shoulder arthroscopic surgery under ISB and had complete clinical data were included in the study. The 357 patients who developed HBEs were included in the HBEs group, and the remaining 2192 in the non-HBEs group. The potential risk factors for HBEs, such as age, sex, past medical history, anesthetic characteristics, and intraoperative medications were collected and compared between the groups. Statistically significant variables were included in a logistic regression model to further evaluate the independent risk factors for HBEs in shoulder arthroscopic surgery under ISB. Results: The incidence of HBEs was 14.0% (357/2549). Logistic regression analysis revealed that the intraoperative use of hydralazine (odds ratio [OR] 4.2; 95% confidence interval [CI] 2.9–6.3), propofol (OR 2.1; 95% CI 1.3–3.6), and dexmedetomidine (OR 3.9; 95% CI 1.9–7.8) before HBEs were independent risk factors for HBEs in patients who received shoulder arthroscopic surgery under ISB. Conclusions: The intraoperative use of antihypertensives such as hydralazine and sedatives such as propofol or dexmedetomidine leads to increased risk of HBEs during shoulder arthroscopic surgery under ISB in the sitting position.

Abstract Background: Novel agents such as proteasome inhibitors have been developed for several years to treat multiple myeloma. Although multiple myeloma is a low-risk disease for developing tumor lysis syndrome (TLS), treatment with these novel therapies might increase TLS risk. Previous studies, mostly case reports or case series, have reported bortezomib-induced TLS in patients with multiple myeloma. This study aimed to investigate risk factors associated with TLS development in multiple myeloma patients.Methods: We retrospectively investigated incidences of laboratory and clinical TLS (LTLS and CTLS, respectively) in patients who received primary therapy for treatment-naive, symptomatic multiple myeloma between May 2007 and January 2018. We used multivariate logistic regression analyses to evaluate the associations between TLS and several parameters previously reported to be associated with increased risk.Results: This study included 210 patients with multiple myeloma, of which ten (4.8%) had LTLS and seven (3.3%) had CTLS. The characteristics of the administered anticancer or prophylactic antihyperuricemic agents were similar between patients with and without TLS. Multivariate analyses revealed that TLS was most strongly associated with bortezomib-containing therapy (odds ratio = 3.40, P = 0.069), followed by male sex (odds ratio = 2.29, P = 0.153). In a subgroup analysis focused on men, treatment with bortezomib-containing therapy was significantly associated with increased risk of TLS (odds ratio = 8.51, P = 0.046).Conclusion: In the present study, we investigated the risk factors associated with TLS development in 210 multiple myeloma patients, which, to the best of our knowledge, is the largest number of patients reported to date. Furthermore, this study is the first to evaluate TLS risk factors in MM by adjusting for the effects of potential confounding factors in patients’ backgrounds. Consequently, we found that bortezomib-containing therapy increases the risk of TLS in male patients with multiple myeloma. TLS risk should be evaluated further in low-risk diseases such as multiple myeloma, since a significant number of novel therapies can achieve high antitumor responses.

Abstract Background: The aims of this study were to describe the epidemiology and demographic characteristics of critically ill children requiring continuous renal replacement therapy (CRRT) at our pediatric intensive care unit (PICU) and to explore risk factors associated with mortality. Methods: A retrospective cohort of 121 critically ill children who received CRRT from May 2015 to May 2020 in the PICU of a tertiary healthcare institution was evalauted. The demographic information, admission diagnosis, indication for CRRT, clinical variables at the initiation of CRRT, time related variables and the laboratory results at initiation of CRRT were compared between survivors and non-survivors.Results: The most common diagnoses were renal disease (30.6%), hemato-oncological disease (12.4%), and sepsis (11.6%). The overall mortality was 29.8%. When compared according to diagnosis at admission, we found that patients with hemato-oncologic disease (73.3%) and those with pneumonia/respiratory failure (72.7%) had the highest mortality, while patients with renal disease had the lowest mortality (5.4%). The most common CRRT indications were: electrolyte or acid base imbalance (38.8%), acute kidney injury (29.8%) and fluid overload (14.9%). There was no relationship between mortality and indication for CRRT. The time interval between PICU admission and CRRT initiation was also unassociated with mortality (p=0.146). In patients diagnosed with sepsis, time until the initiation of CRRT was significantly shorter in survivors compared to non-survivors (p=0.004). Based on multivariate logistic regression, presence of comorbidity (odds ratio: 5.71; %95 CI: 1.16-27.97), being diagnosed with pneumonia/respiratory failure at admission (odds ratio: 16.16; %95 CI: 1.56-167.01), and high lactate level at the initiation of CRRT (odds ratio: 1.43; %95 CI: 1.17-1.79) were independently associated with mortality.Conclusions: In the context of the population studied mortality rate was lower than previously reported. In critically ill children requiring CRRT, mortality seems to be related to underlying disease, presence of comorbidity, and high lactate levels at CRRT initiation. We also found that early initiation of CRRT in sepsis can reduce mortality.

Campylobacter jejuni is an important food-borne pathogen. The main source of this pathogen is poultry and poultry products. Poultry farms of low biosecurity level plays major role in disseminating this pathogen. The objectives of this study were to investigate the occurrence of Campylobacter and identify potential risk factors associated with their presence in layer farms in Northern Jordan. A total of 2524 samples from chickens, litter, water and feed were collected from 35-layer farms. Samples underwent conventional and enrichment isolation methods for Campylobacter. Confirmation was done morphologically, biochemically and by PCR typing. The flock-level prevalence of C. jejuni was 40%, 37%, 20% in chicken cloacae, drinking water and litter respectively. C. jejuni was the only confirmed isolated species. None of the feed samples revealed presence of Campylobacter. The concentration of free residual chlorine was below the recommended standard levels. The risk factors were identified using modified semi-structured questionnaire. There was no significant association between evaluated risk factors and isolation status potentially reflecting small number of study farms. The prevalence rate for C. jejuni is within commonly reported range. High stocking density, short distance between farms, improper hygienic practice and low water chlorine level seems to increase occurrence rate of Campylobacter in layer farms. Educational biosecurity programs regarding C. jejuni transmission and their public health importance needs to be established.

ObjectiveTo determine the risk factors for blood contamination during cerebrospinal fluid (CSF) collection in dogs.Study design and methodsThis is a prospective study of 170 CSF samples. Data collected included signalment of the patient, body condition score, site of CSF collection (cerebellomedullary cistern (CMC) or lumbar cistern (LC)), number of attempts, clinician expertise, final diagnosis, time of day, skull conformation and day of the week. Analysis of the CSF samples was then performed, and the presence of blood contamination (red blood cells >500/µl) was recorded. Logistic regression was used to quantify the association of potential risk factors of the procedure. Multivariate analysis was performed on the variables that were statistically significant.ResultsOf the 170 CSF samples, 53 per cent were collected from the CMC (n=90) and 47 per cent from the LC (n=80). Blood contamination was seen in 20 per cent (n=34) of the samples, 8.9 per cent (n=8) in CMC and 32.5 per cent (n=26) in LC samples. Increased odds of obtaining a contaminated CSF sample were associated with lower level of clinician expertise (odds ratio: 2.5; 95 per cent confidence interval: 0.9–6.7; P=0.046) and with LC versus CMC collection site (odds ratio: 8.1; 95 per cent confidence interval: 2.1–12.9; P=0.001).Clinical significanceThere is increased likelihood of blood contamination when collecting CSF from the LC compared with the CMC site. Increased clinician experience reduced the risk of CSF blood contamination, but none of the other variables examined significantly influenced this.
