HPV vaccination in Croatia (2016-2023): Increased vaccine uptake and declining sex disparities

Abstract Background The Human papillomavirus (HPV) is a known cause of cervical cancer, and is associated with the development of vaginal, vulvar, anal, penile, and head and neck cancer. The availability of the HPV vaccine has enabled generations of young people to be protected from HPV-related cancers. In 2016, a national immunization program targeting 14-year-old girls and boys has been initiated in Croatia. To date, systematic data on HPV vaccination coverage (VC) in Croatia is lacking. This study aims to determine HPV VC, examine trends in HPV vaccination in Croatia from 2016 to 2023 in the context of the national vaccination program, and assess differences between sexes. Methods The study is designed as a retrospective analysis covering the data from 2016 to 2023, collected from primary healthcare providers. HPV VC within 2000-2008 birth cohorts (BC) are analyzed for all vaccinated with at least one dose and assessed by sex. The trend in HPV vaccination is shown using joinpoint regression. The chi-square for trend is used to compare the vaccination coverage of females (FVC) and males (MVC). The rate ratio between FVC and MVC is calculated. Results HPV VR increased significantly among observed BCs from 6,44 % in 2000 BC to 44,22 % in 2008 BC (FVC rose from 10,67 % to 52,78 %, and males MVC from 2,47 % to 36,05 %). Joinpoint analysis revealed a statistically significant increase in all birth cohorts, while the steeper increase is seen in 2000-2006 BCs (APC = 35,47, P < 0,05) than in 2006-2008 BCs (APC = 13,93, P < 0,05). FVC is significantly higher than MVC in all birth cohorts (Extended Mantel-Haenszel chi-square for linear trend = 809.23, P < 0,001). The highest FVC/MVC rate ratio was observed in the initial 2000 BC (4,31), and the lowest in the last 2008 BC (1,46). Conclusions In Croatia, HPV VC continuously increases among observed BCs. The positive trend is present in both sexes, and the rate ratio between female and male cohorts is decreasing. Key messages • The study presents a systematical overview of HPV vaccination coverage in Croatia from the beginning of the national immunization program, which is crucial for monitoring progress. • In the following years, if the revealed trends persist or advance, Croatia could be closer to reaching Europe’s Beating Cancer Plan concerning eliminating HPV-related diseases.

The correlation between medial pattern of intracranial arterial calcification and white matter hyperintensities

Background and aimsDespite reported correlations between intracranial arterial calcification (IAC) and white matter hyperintensities (WMH), little is known about the relationship between IAC pattern and WMH. By differentiating intimal and medial IAC, we aimed to investigate the relationship between IAC pattern and WMH. MethodsConsecutive acute stroke patients were included. IAC pattern was categorized as intimal or medial on plain brain CT. The number of cerebral arteries involved by IAC for each patient was recorded. IAC severity was defined as focal or diffuse. On brain MRI, the burden of WMH was visually graded and classified as absent mild, moderate and severe. Multiple logistic regression was performed to examine the relationship between IAC and WMH. ResultsAmong 265 patients, intimal IAC was detected in 54.7% patients and medial IAC in 48.5% patients. Diffuse IAC was present in 27.9% patients, all of which were medial. WMH was found in 75.5% patients, including 39.6% patients with mild WMH, 26.0% with moderate WMH, and 9.8% with severe WMH. The severity of medial IAC was correlated with WMH occurrence (p < 0.001). Chi-square linear trend suggested the number of arteries involved by medial IAC (p < 0.001) and the severity of medial IAC (p < 0.001) were correlated with WMH burden. Multiple ordinal logistic regression demonstrated a positive correlation of WMH burden with the number of arteries involved by medial IAC (p < 0.001) and the severity of medial IAC (p < 0.001). ConclusionsMedial IAC was correlated with WMH. The dose-effect relationship between medial IAC and WMH suggests underlying shared mechanisms of intracranial large artery disease and small vessel disease.

The Alberta Congenital Anomalies Surveillance System: a 40-year review with prevalence and trends for selected congenital anomalies, 1997-2019.

Current published long-term provincial or territorial congenital anomaly data are lacking for Canada. We report on prevalence (per 1000 total births) and trends in 1997-2019, in Alberta, Canada, for selected congenital anomalies. Associated risk factors are also discussed. We used data from the Alberta Congenital Anomalies Surveillance System (ACASS) to calculate the prevalence and perform chi-square linear trend analyses. From 1997 to 2019, the overall prevalence of neural tube defects was stable, at 0.74 per 1000 total births. The same was true for spina bifida (0.38), orofacial clefts (1.99), more severe CHDs (transposition of the great arteries, 0.38; tetralogy of Fallot, 0.33; and hypoplastic left heart syndrome, 0.32); and gastroschisis (0.38). Anencephaly, cleft palate and anorectal malformation significantly decreased with a prevalence of 0.23, 0.75 and 0.54 per 1000 total births, respectively. Significantly increasing trends were reported for anotia/microtia (0.24), limb reduction anomalies (0.73), omphalocele (0.36) and Down syndrome (2.21) and for hypospadias and undescended testes (4.68 and 5.29, respectively, per 1000 male births). Congenital anomalies are an important public health concern with significant social and societal costs. Surveillance data gathered by ACASS for over 40 years can be used for planning and policy decisions and the evaluation of prevention strategies. Contributing genetic and environmental factors are discussed as is the need for continued surveillance and research.

Rising trend of dengue in urban areas: A challenge.

Dengue, a mosquito-borne illness, is endemic over 100 countries around the world. Dengue cases have been on rise in India in the past decade. The present study was conducted to describe dengue cases of a ward in an urban area. To analyse the 5-year trend of cases of dengue fever, the 5-year trend of disease burden attributable to dengue as a proportion of all consultations, and the 5-year trend of mortality attributable to dengue as a proportion of all deaths in an urban area. The present study is a retrospective record-based study, carried out from January 2014 to December 2019. Descriptive analysis was used to describe the cases. Standard statistical tools such as Chi square for linear trends were utilised for data analysis. Except for a marginal dip in the year 2017, we observed that the trend of dengue significantly increased during the period of our study (Chi square for linear trend = 217.54; P = 0). We also observed a generally significantly increasing trend in burden of dengue as a disease, measured as a proportion of all consultations (Chi square for linear trend = 14302.72; P = 0). Mortality attributable to dengue measured as a ratio of deaths because of dengue and deaths because of all causes also shows a generally increasing trend with a slight decrease in 2018 (Chi square for linear trend = 371.24; P = 0). Dengue cases and the percentage of consultations attributable to dengue show an increasing trend over the past 5 years.

Prevalence of herpes simplex virus types 1 and 2 antibodies among individuals screened in a tertiary hospital in the Eastern province of Saudi Arabia.

The epidemiology of herpes simplex virus (HSV) infections varies among populations depending on their demographic characteristics and exposure. This study describes the prevalence of HSV 1/2 IgG and IgM antibodies among individuals over a period of 5 years. A retrospective study was conducted to collect data on cases tested for HSV-1 and HSV-2 IgG and IgM antibodies for different medical conditions over five years between January 2014 and December 2018. 620 samples were tested for HSV 1/2 IgG and IgM during the study period. The total HSV seropositivity in the study population was 68% (422/620). The total seropositivity excluding children below 6 months of age was 65.3% (313/479). HSV-IgG seropositivity was significantly higher in married individuals (p<0.001, 95% CI 1.61-3.69). The HSV IgG seropositivity was significantly higher in children under the age of 6 months (N=109, 77.30%) than in children between 7 and 24 months old (27.6%) (Chi-square for linear trend, p<0.001), and it then tends to increase with age more than 24 months (Chi-square for linear trend, p=0.011). Eleven children showed laboratory evidence of recent HSV infection (6.2%) as indicated by HSV IgM antibodies and had diverse clinical conditions. HSV infection is highly prevalent in the Eastern Province of Saudi Arabia. Infection is most probably acquired during early childhood, and the tendency increases with age. However, a significant number of mothers are at risk of infection and transferring the infection to their fetuses.

Evaluation of Meningococcal Serogroup C Bactericidal Antibodies after Primary Vaccination: A Multicentre Study, Italy.

Here, we evaluated over time in different cohorts of children vaccinated against serogroup C Neisseria meningitidis, the presence of antibodies with neutralizing activity. A total of 348 sera samples of enrolled children by year since vaccination (<1 year- up to 5 years), starting from February 2016 to December 2017, were collected in three collaborating centers. Meningococcal serogroup C (MenC) antibody titers were measured with a serum bactericidal antibody (SBA) assay using rabbit complement (rSBA) following standard operating procedures. The cut-off of rSBA titer ≥ 8 is considered the correlate of protection. We observed a significantly declining of bactericidal rSBA titers by 23% every year, for every 1-year from vaccination (Adjusted PR = 0.77, 95% CI: 0.71–0.84). The proportions of children with bactericidal antibodies, immunized with the meningococcal serogroup C conjugate (MCC) vaccine, declined from 67.7% (95% CI: 48.6–83.3%) one year after vaccination, to 36.7% (95% CI: 19.9–56.1%) five years after vaccination (chi-square for linear trend, p < 0.001). Children vaccinated with the tetravalent meningococcal serogroup ACWY vaccine resulted in a high proportion of bactericidal rSBA MenC titer ≥ 1:8 (90.6%, 95% CI: 79.3–96.9%) after a mean time of seven months. Overall, the results provide some evidences on the evaluation of meningococcal serogroup C bactericidal antibodies after primary vaccination.

Hydroxychloroquine/Chloroquine Prophylaxis among Health-care Workers: Was it Really Preventive? - Evidence from a Multicentric Cross-sectional Study.

Background:Despite the low level of clinical evidence in hydroxychloroquine (HCQ) favor, it was prescribed for pre- and post-exposure prophylaxis in India and worldwide. In absence of a large randomized control trial, the evidence needs to be generated through observation study, hence the study was conducted to find the evidence for prophylaxis of HCQ.Materials and Methods:A multi-centric cross-sectional study involving government hospitals was chosen for serosurvey conducted from August 21, 2020, to November 20, 2020. Questionnaire was adopted from WHO. Data about chloroquine (CQ) use among health-care workers (HCWs) were added and the duration of CQ intake was also noted.Results:A total of 2,224 HCWs were recruited. The mean duration of time of taking HCQ was 7.1 weeks (standard deviation ± 6.1 weeks, median = 4 weeks with IQR, 3–10 weeks). Training on personal protective equipment (PPE), knowledge of handwashing, direct care to the patient, availability of alcohol hand rub, close contact with the patient, duration of contact, and usage of PPE were associated with HCQ intake. The antibody formation in group taking HCQ was 16.9% compared to 19.8% not taking it (P = 0.08). The Chi-square for linear trend for weeks of HCQ intake and antibody formation. However, the same was not statistically significant (Chi-square = 3.61, P = 0.06).Conclusion:Our study did not find a statistically significant association in the large multicentric study. The absolute difference of 2.9% in the two groups may not be sufficient to warrant its widespread use for prophylaxis.

Changes in anticoagulant prescription in a general hospital in 2008-2018

Aim. To study the structure of anticoagulant prescription in a general hospital to identify trends and contributing factors.Materials and methods. The study was conducted in an urban general hospital. According to retrospective retrieval from electronic health records, total 17,129 patients received anticoagulants from 2008 to 2018. Formal appropriateness of oral anticoagulants (OАС) prescriptions for 6,638 patients with atrial fibrillation (AF) was analyzed with CHA2-DS2-VASc score.Results. Appearance of recommendations for the direct oral anticoagulants (DOAC) prescription in clinical guidelines for venous thromboembolism (VTE) and AF management contributed to steady increase in the DOAC taking and decrease in the proportion of warfarin prescription. From 2011 to 2018, the proportion of patients with DOACs prescription increased from 1.7% to 81.5%. The most common indications for anticoagulant were ischemic stroke prevention in AF and VTE with mean rate 75.3% and 23.2%, respectively for the 2011-2018 period. Steady increase in low-molecular-weight heparin (LMWH) prophylactic prescriptions was also shown (Chi-square for linear trend=1340, df=1, p&lt;0.0001). Since 2014, the prescription of LMWH in prophylactic doses increased dramatically, probably related to implementation of computerized decision support system (CDSS) for VTE prevention in the hospital.Conclusion. The study showed that in a general hospital anticoagulants were prescribed in 19% of hospitalized patient. Not only the new clinical recommendations based on the results of the recent studies on anticoagulants efficacy and safety (external factors), but also implementation standard operating protocols and CDSS, providing physicians current information about the relevant clinical recommendations (internal changes), could influence the appropriateness of anticoagulants prescription.

Interference and Impact of Dysmenorrhea on the Life of Spanish Nursing Students.

Dysmenorrhea is a cause of absenteeism in universities which, in the context of nursing studies, may affect mandatory attendance. Moreover, presenteeism is associated with medication errors, patient falls, and a reduced quality of patient care. This study sought to identify the degree of interference of dysmenorrhea on daily life and its impact on academic performance among Spanish nursing students, and to explore the reasons for presenteeism. A cross-sectional descriptive study was conducted on 261 nursing students. Data were collected using a self-administered questionnaire. The chi square tests, chi-square linear trend, Student’s t-test, one-way analysis of variance of polynomial contrasts, and post hoc tests for the bi-variate analysis were used to compare the participants’ responses regarding their type of dysmenorrhea and pain intensity. In addition, a multivariate regression was performed to predict absenteeism. The answers to the open questions were analyzed using thematic content analysis techniques. We observed 62.8% of absenteeism and 92.7% of presenteeism due to dysmenorrhea. Absenteeism was observed to be 3.079 (confidence interval (CI): 95%1.724–5.499; p < 0.001) times more likely among women with severe menstrual pain, 2.513 (CI 95%1.314–4.807; p = 0.005) times more in those suffering from menstrual nausea and 1.936 (CI 95%1.098–3.411; p = 0.022) times more frequent in those suffering from diarrhea. The reasons for presenteeism were grouped into five categories: the pain was bearable, it is not a reason to be absent, others don’t consider it a reason to be absent, responsibility and guilt, and academic consequences. Dysmenorrhea can have a significant impact on academic performance. The concern among students about the academic repercussions and even feelings of guilt and incomprehension from others leads to high rates of presenteeism with potentially negative consequences for patient care.

Maternal diabetes mellitus as an independent risk factor for clinically significant retinopathy of prematurity severity in neonates less than 1500g

BackgroundRetinopathy of prematurity (ROP) is a significant morbidity in preterm babies. Multiple risk factors for severe ROP have been extensively studied, however, only a few studies have included maternal diabetes mellitus (MDM) in their assessment. ROP and diabetic retinopathy are both retinal vascular diseases in which there is leakage and/or neovascularization from damaged retinal vessels. Diabetes may affect ROP development; however, there are conflicting results on the association between MDM and ROP.ObjectiveTo determine if MDM is an independent risk factor for clinically significant ROP (ROP > Stage II) in neonates weighing less than 1500g.Design/MethodWe conducted a retrospective cohort study of neonates weighing <1500g who were delivered or transferred into our institution from 2007 through 2017. Logistic regression was used to analyze the association between severe ROP and MDM. The risks for the different stages of ROP from MDM were compared using chi-square linear trend test.ResultsWe extracted 883 paired maternal-neonatal data. The mean (standard deviation) gestational age and birthweight were 28.5 (2.9) weeks and 1052.7 (300.9) grams, respectively. Of the 883 mothers, 72 (8.2%) had DM. The incidence of ROP and severe ROP was 42.4% (374/883) and 6.5% (57/883) respectively. The odds ratio comparing MDM and severe ROP was 3.47 [95% CI: 1.51–7.96]; p<0.01). Compared to Stage I, the risk of MDM in infants with ROP increased from 1.49 in Stage II ROP to 2.59 in Stages III&IV. Severe ROP was associated with infant steroid use (OR: 5.92 [95% CI: 2.83–12.38]; p <0.01), sepsis (OR: 2.13 [95% CI: 1.09–4.14]; p = 0.03) chorioamnionitis (OR: 1.90 [95% CI: 1.03–3.50]; p = 0.04), and maternal steroid use (OR: 0.51 [95% CI: 0.32–0.79]; p<0.01).ConclusionMaternal diabetes is associated with ROP and the strength of association increased with increasing severity of ROP.

Sequential Organ Failure Assessment Score As a Predictor of Outcome in Sepsis in Pediatric Intensive Care Unit.

Sequential organ failure assessment (SOFA) score is used as a predictor of outcome of sepsis in the pediatric intensive care unit. The aim of the study is to determine the application of SOFA scores as a predictor of outcome in children admitted to the pediatric intensive care unit with a diagnosis of sepsis. The design involved is prospective observational study. The study took place at the multidisciplinary pediatric intensive care unit (PICU), tertiary care hospital, South India. The patients included are children, aged 1 month to 18 years admitted with a diagnosis of sepsis (suspected/proven) to a single center PICU in India from November 2017 to November 2019. Data collected included the demographic, clinical, laboratory, and outcome-related variables. Severity of illness scores was calculated to include SOFA score day 1 (SF1) and day 3 (SF3) using a pediatric version (pediatric SOFA score or pSOFA) with age-adjusted cutoff variables for organ dysfunction, pediatric risk of mortality III (PRISM III; within 24 hours of admission), and pediatric logistic organ dysfunction-2 or PELOD-2 (days 1, 3, and 5). A total of 240 patients were admitted to the PICU with septic shock during the study period. The overall mortality rate was 42 of 240 patients (17.5%). The majority (59%) required mechanical ventilation, while only 19% required renal replacement therapy. The PRISM III, PELOD-2, and pSOFA scores correlated well with mortality. All three severity of illness scores were higher among nonsurvivors as compared with survivors ( p < 0.001). pSOFA scores on both day 1 (area under the curve or AUC 0.84) and day 3 (AUC 0.87) demonstrated significantly higher discriminative power for in-hospital mortality as compared with PRISM III (AUC, 0.7), and PELOD-2 (day 1, [AUC, 0.73]), and PELOD-2 (day 3, [AUC, 0.81]). Utilizing a cutoff SOFA score of >8, the relative risk of prolonged duration of mechanical ventilation, requirement for vasoactive infusions (vasoactive infusion score), and PICU length of stay were all significantly increased ( p < 0.05), on both days 1 and 3. On multiple logistic regression, adjusted odds ratio of mortality was elevated at 8.65 (95% CI: 3.48-21.52) on day 1 and 16.77 (95% confidence interval or CI: 4.7-59.89) on day 3 ( p < 0.001) utilizing the same SOFA score cutoff of 8. A positive association was found between the delta SOFA ([Δ] SOFA) from day 1 to day 3 (SF1-SF3) and in-hospital mortality (chi-square for linear trend, p < 0.001). Subjects with a ΔSOFA of ≥2 points had an exponential mortality rate to 50%. Similar association was-observed between ΔSOFA of ≥2 and-longer duration of inotropic support ( p = 0.0006) with correlation co-efficient 0.2 (95% CI: 0.15-0.35; p = 0.01). Among children admitted to the PICU with septic shock, SOFA scores on both days 1 and 3, have a greater discriminative power for predicting in-hospital mortality than either PRISM III score (within 24 hours of admission) or PELOD-2 score (days 1 and 3). An increase in ΔSOFA of >2 adds additional prognostic accuracy in determining not only mortality risk but also duration of inotropic support as well.

HCV Antibody Prevalence and Genotype Evolution in a Teaching Hospital, Calabria Region, Southern Italy Over A Decade (2008-2018)

Background: Hepatitis C Virus (HCV) infection is associated with a high risk of developing liver diseases. Globally, HCV prevalence is changing due to improving health care procedures, population movement, and availability of new antiviral therapy. In Italy, data on the prevalence of HCV infection are insufficient, out-dated, and restricted to specific areas. Objective: Between 2008 and 2018, we investigated HCV antibody (Ab) seroprevalence and genotypes distribution among patients presenting for testing at our Teaching Hospital. Methods: The HCV Ab and genotyping assays were performed by routine diagnostic methods. Chi-square for linear trend was carried out by OpenEpi (v3.01). Results: Among 120,009 consecutive patients, 5877 subjects were HCV Ab positive (4.89%). During the observational period 2008-2018, prevalence decreased significantly (p&lt;0.001) from 4.7% in 2008 to 3.6% in 2018. HCV1b was the most prevalent subtype (47.2%) followed by HCV2a/2c (20.2%), and HCV3 (9.7%), while HCV4 showed a rate of 6.1%. HCV infection was more frequent in males (55.4%) than in females (44.6%). Overall, most infected patients were born before 1949. Conclusion: Epidemiological analyses are important to understand the evolution of the HCV epidemics under the influence of several factors, such as risk behaviour and therapy with direct-acting antivirals.

On-demand cesarean section: assessing trends and socioeconomic disparities.

ABSTRACTOBJECTIVE:to measure prevalence, evaluate trends and identify socioeconomic differences of on-demand cesarean section in the municipality of Rio Grande (RS), extreme south of Brazil, in 2007, 2010, 2013 and 2016.METHODS:all the puerperae residing in this municipality who had cesarean deliveries in one of the only two local maternity hospitals in the period 01/01-31/12 of the aforementioned years were part of this transversal study. Puerperae were interviewed using a single, standardized questionnaire at the hospital within 48 hours after delivery. The outcome was assessed based on the mothers’ report that the cesarean section was performed according to their request. The analysis consisted of the observation of the outcome's frequency in each year and the evaluation of its prevalence throughout this period through the chi-square linear trend test. Socioeconomic inequalities were assessed based on household income and women's schooling using the Slope Index of Inequality and the Relative Index of Inequality.RESULTS:In these four years, 5,721 cesarean deliveries were recorded among mothers living in this municipality (1,309 in 2007, 1,341 in 2010, 1,626 in 2013 and 1,445 in 2016). In this period, the rate of on-demand cesarean sections increased by 107%, from 10.5% (95%CI: 8.9% -12.2%) of the deliveries in 2007 to 21.7% (95%CI: 19.5% -23.8%) in 2016. This increase was more evident among those with lower household income and schooling level. Absolute inequality also increased, especially regarding schooling, while relative inequality sharply declined when assessed by household income.CONCLUSIONS:The increased on-demand cesarean sections in the study location is unsettling, despite the decreasing gap between extreme categories as a consequence of higher levels of this procedure among women of lower income and worse schooling.

P4624Predictive performance of CRUSADE bleeding score in non ST elevation acute coronary syndrome patients treated with ticagrelor versus clopidogrel

Abstract Introduction CRUSADE score is commonly used for bleeding risk stratification in the context of acute coronary syndrome (ACS). However, the study validating it was performed before ticagrelor was available. Purpose To compare the predictive performance of CRUSADE score in two groups of non-ST elevation ACS (NSTEACS) patients, one treated with ticagrelor and another with clopidogrel. Methods Retrospective study of 2077 NSTEACS patients admitted between January 2014 and September 2017 and included in a multicentre national registry. Group 1 was composed by patients medicated with ticagrelor, and Group 2 with clopidogrel. Patients with bleeding history were excluded. The primary endpoint (PE) results from a composite which includes: in-hospital major bleeding (MB) according to the Registry criteria, need for red blood cell transfusion (RBCT), or haemoglobin drop ≥2g/dL (HbD). The groups were compared according to their demographic, clinical and laboratory characteristics. The occurrence of the PE (and its components) across CRUSADE risk categories was assessed by Chi-square for linear trend. The performance of CRUSADE score for PE prediction in each cohort was assessed by Receiver Operator Characteristics (ROC) curves. Results Group 1 included 662 (31.9%) and Group 2 1415 (68.1%) patients. Mean CRUSADE score was higher in Group 2 (23.1±14.7 versus (vs) 26.7±16.3, p=0.001). No difference was observed regarding the PE (14.8% vs 17.0%, p=0.200) and its components. With the exception of MB in Group 1 (p-trend=0.425), the relative occurrence of the PE and its components increased across CRUSADE risk categories [Figure 1. panel A]. In-hospital mortality was numerically superior in Group 2, but did not reach statistical significance (1.1% vs 1.6%, p=0.368). In both groups, the performance of CRUSADE score in predicting the PE was modest (Group 1 AUC=0.59 and p=0.006, Group 2 AUC=0.62 and p&lt;0.001), and no difference was observed when comparing the two groups (P value for ROC curves comparison = 0.899) [Figure 1. panel B and C respectively]. Figure 1 Conclusion In this study based on a national registry of NSTEACS patients, the use of ticagrelor did not influence the occurrence of bleeding related events and it did not change the predictive performance of the CRUSADE score. According to this analysis, CRUSADE score may be applied without limitation to NSTEACS patients managed with ticagrelor.

Descriptive Study of Foodborne Disease Using Case Monitoring Data in Shandong Province, China, 2016-2017

In order to generate data on the burden of foodborne diseases in Shandong Province, we aimed to use the case monitoring data of foodborne diseases from 2016 to 2017 to estimate. Data were obtained from the foodborne disease surveillance reporting system with dates of onset from Jan 1, 2016, to Dec 31, 2017, in Shandong, China. The places of food exposure were categorized by settings as follows: private home, catering facility, collective canteens, retail markets, rural banquets and other. Exposed food is divided into 23 categories. Overall incidence rate and proportions by exposure categories, age, and sex-specific incidence rates were calculated and sex proportions compared. Approximately 75.00% of cases who had at least one exposure settings were in private homes. The most frequently reported exposed food was a variety of food (meaning more than two kinds of food). The two-year average incidence rate was 75.78/100,000, sex-specific incidence rate was much higher for females compared to males (78.23 vs. 74.69 cases per 100,000 population). An age-specific trend was observed in the cases reported (Chi-Square for linear trend, χ2=4.39, P=0.036<0.05). A preliminary estimate of 14 million cases of foodborne diseases in Shandong province each year. Future studies should focus on cross-sectional and cohort studies to facilitate the assessment of the distribution and burden of foodborne disease of the population in Shandong. Considering strengthening the burden of foodborne diseases in foodborne disease surveillance is also a feasible way.

1524. Are Providers Shifting from NTF to Fosfomycin for Inpatient UTI? Big Data Reveals Small Shifts

BackgroundFosfomycin (FOS) and NTF (NTF) are IDSA guideline approved drugs for acute cystitis in women. However, their activity against multi drug-resistant Gram-negatives may be driving increased use among inpatients with more complicated UTI. We evaluated trends in inpatient prescribing of these UTI-specific agents in the predominantly male population of the national VA system over a 7-year period.MethodsAll inpatient bar coded administrations for FOS and NTF at every VA facility nationwide from 2011 to 2017 were captured through a data analytics platform which extracts data from the VA Data warehouse. Antibiotic days of therapy and rates per 1,000 patient-days (DOT/1,000CD) were extracted by year and compared using Mantel-Haenszel chi square for linear trend (MH OR). Demographics were captured via administrative data.ResultsPrescriptions from over 65 million patient-days spanning 7 years and all inpatient units in 129 VA facilities were included. Approximately 90% of patients were male with a mean age range of 55–64 years. FOS use increased from 128 prescriptions in 2011 to a high of 1,230 in 2016 and 1,003 in 2017 (figure). At the maximum in 2016, prescription rates increased almost 10-fold compared with 2011 (MH OR 9.8, P < 0.001). NTF prescriptions declined from 26,590 in 2011 to 19,343 in 2017. Rates decreased 25% from 2.8 to 2.1, MH OR 0.75, P < 0.001. In 2017, FOS and NTF usage rates were highest in rehabilitation/spinal cord units (table).ConclusionIn this large nationwide cohort, FOS use increased almost 10-fold among predominantly male inpatients while NTF use declined slightly. NTF is still used orders of magnitude more than FOS, even after adjusting for extended days of activity of FOS. Both agents retain activity against many MDR GNRs but differences in efficacy, tissue penetration, familiarity and availability likely influence the choice for oral UTI-specific treatment. 2017 Data ICU MEDSURG NH PSYCH REHAB/SCIFOS DOT/1,000CD0.060.150.070.030.73NTF DOT/1,000CD0.561.462.412.559.35FOS days2838222928315NTF days2513,6997,8262,6344,013 Disclosures All authors: No reported disclosures.

An evaluation of reporting of consent declines in three high impact factor journals

Background Informed consent confers upon participants the right to decline or accept participation in a study in equal measure. Consent declines can be used as a potential metric to assess the adequacy of the informed consent process. Limited literature is available on the reporting of consent declines in Clinical Research. We evaluated randomized controlled trials published in three high-impact factor journals for consent declines (four-year period) to assess the extent of exertion of autonomy by research participants. Methods CONSORT flow charts in RCTs published in New England Journal of Medicine (NEJM), The Lancet and Journal of the American Medical Association (JAMA) between 2012 and 2015 were evaluated. The total and per journal proportion of RCTs reporting consent declines was calculated. Percentage of consent declines was also compared based on number of centers (single centric vs. multicentric) and type of setting (developed vs. developing). Between-groups analysis was done using Chi Square, Chi Square for trend and a Crude odds ratio [95% C.I] (cOR) were calculated. Results Only 3.7% (1103/29,825) of the published articles were RCTs. Of the 1103 RCTs, only 532 (48.2%) reported consent declines. JAMA had the highest RCTs reporting consent declines (171/267.64%), the Lancet [129,150/781,924, 16.5%] had the most participants declining consent. Difference was significant using Chi square for linear trend [ p &lt; 0.00001]. Consent decline rate was higher in developed countries relative to developing countries [cOR(95% C.I): 2.27(2.23,2.32), p &lt; 0.000001] and in single centric versus multicentric studies [cOR (95% C.I): 3.63(3.56,3.71), p &lt; 0.0000001]. Conclusion Both authors and journal editors need to ensure better reporting of consent declines.

Multicentric Assessment of the Hong Kong Liver Cancer Staging System in Chinese Patients Following Transarterial Chemoembolization.

We aimed to validate the performance of the hepatitis B-based Hong Kong Liver Cancer (HKLC) staging system compared with the Barcelona Clinic Liver Cancer (BCLC) staging system in Chinese hepatocellular carcinoma (HCC) patients treated with conventional transarterial chemoembolization (TACE) as the initial treatment. The study was approved by the Institutional Review Boards at all participating centers. This retrospective study included 715 patients with HCC who underwent TACE as the initial treatment between January 2008 and December 2016 at three Chinese institutions. All of the patients calculated HCC stage using 5-substage HKLC (HKLC-5), 9-substage HKLC (HKLC-9), and the BCLC system. Based on overall survival (OS), these three staging systems' performance on treatment outcome prediction were compared using C statistic, Akaike information criterion (AIC), area under the receiver operating characteristic curve (AUC), linear trend Chi-square, likelihood ratio Chi-square, and calibration plots, respectively. The median OS was 10.1months. Compared with the BCLC system, the HKLC system, especially HKLC-9, showed better performance on survival prediction (HKLC-9: C = 0.689, AIC = 6646.162; HKLC-5: C = 0.683, AIC = 6662.663; BCLC: C = 0.680, AIC = 6654.146), homogeneity (likelihood ratio Chi-square: HKLC-9 = 232.38, HKLC-5 = 215.87, and BCLC = 224.39, P < 0.001), and calibration (R2: HKLC-9 = 0.923, HKLC-5 = 0.916, and BCLC = 0.914). HKLC-9 outperformed on AUC at 6-, 12-, and 24-month survival prediction than HKLC-5 and BCLC. BCLC showed better performance on monotonicity (linear trend Chi-square: HKLC-9 = 121.641, HKLC-5 = 117.389, and BCLC = 125.752; P < 0.001). Combining survival prediction, discrimination, and calibration, the HKLC, especially HKLC-9 system, performed better for Chinese patients treated with TACE than the BCLC system.

Association of depression, stress, and anxiety with type 2 diabetes mellitus: A case-control study

Background: The burden of type 2 diabetes mellitus (T2DM) is increasing due to aging, rising living standards, and changing lifestyles. Along with this, the presence of some psychological factors such as depression, anxiety, and stress have also been hypothesized as potential risk factors for T2DM. Objectives: The objective is to study the association of depression, anxiety, and stress with T2DM. Materials and Methods: This case–control study was conducted in diabetes outpatient department and urban field practice area of GMC Nagpur with 100 cases and 100 age- and gender-matched controls, respectively. Apart from assessing sociodemographic details and anthropometric measurement, the presence and severity of depression, anxiety, and stress were assessed using Hindi translated and validated version of Depression Anxiety and Stress Scale-21. Chi-square for linear trend followed by crude and age-gender adjusted odds ratio (OR) was calculated for each factor under the study. Results: A positive linear association was seen with increasing levels of each depression, anxiety, stress, and T2DM. A strong association was seen between the presence of depression, anxiety, stress, and T2DM, AOR = 4.02 (2.48–8.05), 5.77 (3.03–10.98), and 6.71 (3.56–12.63), respectively. Conclusion: Depression, stress, and anxiety were seen to be strongly associated with T2DM.

Visual-spatial and temporal characteristics related to infectious Tuberculosis epidemics in Guangxi Zhuang Autonomous Region, 2012-2015

Objective: To study the spatial and temporal mode of infectious TB transmission in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data related to infectious TB case (Include smear and/or culture positive patients) in Guangxi were collected from the National Notifiable Disease Reported System (NNDRS) from 2010 to 2015. Spatial-temporal analysis and prediction were performed by SaTScan 7.0.2, GeoDa 1.8.12, R program v 3.3.1 and SPSS 19.0 software, using the time series model, Moran's I global and local spatial autocorrelation (Empirical Bayes adjustment). Kulldorff 's space-time scan statistics displayed by R software was used to identify the temporal and spatial trend of TB. Results: The total number of infectious TB cases, collected from NNDRS was 76 151, and showing a decreasing trend on annual incidence (value of Chi-square for Linear trend=3 464.53, P-value=0.000). The forecast value of TB cases in 2016 was 7 764 (4 971-10 557), with peak in March, analyzed through the Winters'multiplicative model. The Moran's I global Statistics was greater than 0 (0.257-0.390). TB cluster seemed to have been existed for several years. The most significant hot spots seemed to be mainly located in the central and western parts of Guangxi, shown by local spatial autocorrelation statistics and the result from space-time scanning.Counties or districts that located in the east parts of Guangxi presented the low-low relation (significant cold spots). The situation of infectious TB seemed migratory. Conclusions: Our data showed an annual decreasing trend of incidence on infectious TB with temporal concentration in spring and summer. Main clusters (hot spots) were found to be located in the central and western parts of Guangxi. Hopefully, our findings can provide clues to uncover the real mode of TB transmission at the molecular-biological level.
