Abstract

Background: Recruiting of sufficient numbers of donors of blood products is vital worldwide. In this study we assessed the efficacy and cost-effectiveness of telephone calls and SMS reminders for re-recruitment of inactive blood donors. Methods: This single-centre, non-blinded, parallel randomized controlled trial in Guangzhou, China included 11,880 inactive blood donors whose last donation was between January 1 and June 30, 2014. The donors were randomly assigned to one of two intervention groups (telephone call or short message service [SMS] communications) or to a control group without intervention. SMS messages with altruistic appeal were adopted in the SMS group; in addition to altruistic appeal, reasons for deferral of blood donation were also asked in the telephone group. All participants were followed up for 1 year. The primary outcome was re-donation rate, and rates in different groups were compared by intention-to-treat (ITT) analysis and estimation of the average treatment effect on the treated (ATT). Secondary outcomes were the self-reported deterrents. Other outcomes included the re-donation interval, and the incremental cost-effectiveness ratio (ICER) of telephone calls and SMS reminders on re-recruitment. Results: ITT analysis revealed no significant differences in the re-donation rate among the three groups. ATT estimations indicated that among compliers, telephone calls significantly increased re-donation compared to both SMS reminders and no intervention. Donor return behaviour was positively associated with receiving reminders successfully, being male, older age, and previous donation history. The SMS reminder prompted donors to return sooner than no reminder within 6 months, and according to ICER calculations, SMS reminders were more cost-effective than telephone calls. Donors reported time constraints as the most main causes of self-deferral in the telephone group, and altruistic appeal had a positive effect on these donors. Conclusions: Interventions to reactivate inactive blood donors can be effective, with telephone calls prompting more donors to return but at a greater cost than SMS messages. SMS reminder with altruistic appeal can urge donors to re-donate sooner within 6 months than no reminder.

AbstractBackground Endoscopic ultrasound is useful for obtaining high-resolution images of pancreaticobiliary diseases, but is not readily available for physical checkups. In this study, we evaluated the safety and efficacy of single-session esophagogastroduodenoscopy and endoscopic ultrasound in the detection of upper-gastrointestinal and pancreaticobiliary diseases using a forward-viewing radial scan ultrasonic endoscope. Methods A total of 148 patients who were scheduled for upper-gastrointestinal screening using an endoscope were prospectively included. All patients were examined by EUS in combination with EGD using a forward-viewing radial scan ultrasonic endoscope. The primary endpoint was the safety of the procedures. The secondary endpoints were the prevalence of diseases, the basal imaging capability of EUS, the procedure time, total dose of propofol, and the correlation between background factors and the prevalence of pancreatic disease. The imaging capability at each region was scored as 0 (invisible) to 2 (sufficient visualization to evaluate the organs). Results Intraoperative hypotension occurred as an adverse event of intravenous anesthesia in one patient. There were 82 pancreaticobiliary findings and 165 upper-gastrointestinal findings (malignancy not included). Follicular lymphoma of the intra-abdominal lymph nodes was detected in one patient. The mean imaging scores of each section were 1.95 (pancreatic head and papilla), 2.0 (pancreatic body), 1.99 (pancreatic tail), and 1.89 (common bile duct and gallbladder). Age, history of diabetes mellitus, and smoking history were significantly associated with the prevalence of pancreatic diseases. Conclusion The simultaneous performance of EGD and EUS using a new ultrasonic endoscope is tolerable and safe for upper-gastrointestinal and pancreaticobiliary screening.

Abstract
Background: Aortic stenosis (AS) causes left ventricular (LV) pressure overload, leading to adverse LV remodeling and dysfunction. We examined the impact of severe AS and its consequent increase in LV afterload on myocardial deformation and rotational mechanics by 2-dimensional (2D) and 3-dimensional (3D) speckle-tracking echocardiography.
Methods: We prospectively measured various strain parameters in 168 patients (42% female, mean age 72±12 years) with severe AS and LV ejection fraction (EF) ≥50%, and compared them to normal values found in literature. 2D and 3D images were analyzed for global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), basal rotation, apical rotation, and peak systolic twist. We further assessed the degree of concordance between 2D and 3D strain, and examined their association with measures of LV preload and afterload.
Results: Patients with severe AS exhibited significantly lower GLS and GRS but higher GCS, apical rotation, and twist by 2D and 3D echocardiography compared with published normal values (P=0.003 for 3D twist,P<0.001 for all others). There was modest agreement between 2D and 3D GLS measurements (concordance correlation coefficient 0.49, 95% confidence interval 0.39-0.57). GLS was modestly correlated with valvulo-arterial impedance, a measure of LV afterload (r=0.34, p<0.001 for 2D and r=0.23, p=0.003 for 3D).
Conclusion: Patients with severe AS demonstrate lower-than-normal GLS and GRS as a result of increased afterload but appear to compensate with higher-than-normal GCS, apical rotation, and twist in order to maintain a preserved LVEF. Our study provides, to our knowledge, the most comprehensive analysis to date of myocardial deformation and rotational mechanics by 2D and 3D speckle-tracking echocardiography in patients with severe AS and preserved LVEF.

Abstract
Background: The problem of AIDS response has not only involved public health, but also had a great impact on the family burden.The objective of this study was to estimate the preventive and curative care expenditure(PCE)for AIDS of Hunan Province in 2017 based on System of Health Accounts 2011(SHA2011)by quantity,financing scheme,health provider,health function,and to analyses the factors affecting patients' medical burden.Methods: Through stratified multi-stage sampling method, 1336 institutions were surveyed to obtain AIDS prevention and control data, and the official data collected from Health Statistical Yearbook, Health Financial Annual Reports and Government Input Monitoring System were used to estimate the AIDS PCE based on SHA2011. Univariate analyses and ordered logistic regression were used to evaluate the factors affecting the medical burden of AIDS patients.Results: The AIDS PCE of Hunan Province in 2017 was 266.67 million, mainly flowed to hospitals and disease prevention and control institutions. The proportions of curative care expenditure(CCE) and prevention expenditure were 51.39% and 48.61% respectively. Prevention expenditure were mainly used for traditional prevention methods. All prevention expenditure and 88.52% of CCE were borne by public financing scheme. Family health expenditure accounted for 11.12% of CCE，but there were still some people with heavy burden of treatment. Non insurance, co-infection and length of stay are risk factors to the total hospitalization expenses(Totalexp)and the out-of-pocket payments(OOPs)(all p <0.05,OR>1). Taking the age group under 30 as the reference, the partial regression coefficient of the age group over 60 was statistically significant (OR (Totalexp) =1.809, OR (OOPs) =0.30).Conclusion:The financing structure of the PCE for AIDS in Hunan Province was relatively stable and the flow of institutions was reasonable. The functional flow of expenditure embodied the principle of "prevention first". China should incorporate oral PrEP into the national guidelines as soon as possible to improve the allocation efficiency of AIDS prevention resources. Meantime, several measures should be taken to reduce the medical burden of AIDS patients, including expanding the scope of government assistance, adjusting insurance compensation measures, increasing the rate of patients participating in insurance,encouraging commercial insurance to join the AIDS insurance system,and controlling length of stay in hospital.

Abstract

Background

Multidrug-resistant tuberculosis is a type of tuberculosis that is resistant to at least the first line anti-tuberculosis drugs namely, Rifampicin and Isoniazid. Multidrug-resistant tuberculosis has continued to be a challenge for tuberculosis control globally. Globally 600,000 people were newly eligible for Multidrug-resistant tuberculosis treatment with an estimated 240,000 deaths annually. There are few numbers of multi drug resistant tuberculosis studies in different regions of Ethiopia. However, most of these studies were restricted only to a single hospital and there is no published information regarding multi drug resistant tuberculosis in Tigray region. Therefore, the aim of this study was to assess the determinants of multidrug resistant tuberculosis among adults undergoing treatment for tuberculosis in Tigray region, Ethiopia.Methods

A hospital based unmatched case control study was conducted from April to June, 2019. Simple random sampling method was used to select 85 cases and 169 controls. Primary data was collected by face-to-face interview and secondary data by reviewing patients’ charts using pretested structured questionnaires. The data were entered and cleaned using Epi data manager then exported to SPSS for analysis. Binary Logistic regression model was used to test the association between independent and dependent variables. Model fitness was checked using Hosmer-Lemeshow goodness-of-fit and Variance inflation factor was used to assess multi collinearity between the independent variables. Variables at p-value less than 0.25 in bivariate analysis was entered into a multivariable analysis to identify the determinant factors of multi drug resistant tuberculosis. Finally, level of significance was declared at p-value <0.05.Results

A total of 254 participants with 85 cases and 169 controls were included in this study. Of the respondents, 62 (36.7%) among the controls and 48 (56.5%) among the cases were living in rural residence. Rural residence [AOR=2.54;95%CI=1.34,4.83], HIV[AOR=4.5;95%CI=1.4,14.2], relapse [AOR=3.86;95%CI;1.98,7.5], return after lost follow up [AOR=6.29;95% 1.64,24.2], treatment failure [AOR=5.87; CI=1.39,24.8] were among the determinants of Multi drug resistance tuberculosis.Conclusion

Rural residence, HIV, relapse, return after lost follow up and treatment failure were the identified determinant factors of Multi drug resistance tuberculosis.

Published: December 2019

Abstract
Background Cognitive impairment may be correlated with cardiovascular dysautonomia, including blood pressure (BP) dysregulation, in Parkinson’s disease (PD), but the association between these factors in dementia with Lewy bodies (DLB) is uncertain. This study aimed to clarify whether cardiovascular dysautonomia had an influence on cognitive function in Lewy body disease or not. Methods 99 patients with de novo PD (n=75) and DLB (n=24) were evaluated using the Mini-Mental State Examination (MMSE) and Frontal Assessment Battery (FAB). Cardiac 123I-metaiodobenzylguanidine (MIBG) scintigraphy, orthostatic hypotension (OH), supine hypertension (SH), postprandial hypotension (PPH), nocturnal BP fall in 24-hour ambulatory blood pressure monitoring (ABPM) and constipation were estimated. Associations of these factors with cognitive and executive dysfunction were examined. Results In DLB, MIBG uptake was reduced and OH, PPH and SH were severely disturbed, compared to PD. The nocturnal BP fall in ABPM was lower in DLB, and the failure of nocturnal BP fall in PD was associated with MMSE, after adjustment for other clinical features. FAB was significantly associated nocturnal BP fall, age and SH in PD, but no significant correlations among factors were found for DLB. Conclusion The significant association between nocturnal BP dysregulation and cognitive or executive decline in PD might be due to impaired microvascular circulation or invasion of α-synuclein in the CNS. The lack of a correlation of BP insufficiency with cognitive impairment in DLB suggests initial involvement of Lewy body pathology in the neocortex, regardless of Lewy body invasion of the autonomic nervous system.

Abstract

Background: Very few studies consider the oral health status and quality of life in HIV-1 exposed uninfected (HEU) children. The aim of this study was to estimate the prevalence of caries in primary teeth and its oral health related quality of life impacts in HEU children compared to HIV-unexposed-uninfected (HUU) children, whilst adjusting for confounding covariates. Methods: This study uses data from the Ugandan site of the ANRS 121741 PROMISE- PEP trial (ClinicalTrials.gov, number NCT00640263) conducted in 2009-2013 that recruited mothers with HIV-1 and their uninfected children. Of 244 HEU-children-caregiver pairs available at the end of the one-year trial, 166 were re-enrolled in the ANRS 12341 PROMISE-PEP M&S study at 5-7 years and 164 were included in this study. These were age and sex-matched with 181 HUU children-caretaker comparators. Caries experience was recorded using World Health Organization’s Decayed, Missed and Filled teeth (dmft/DMFT) indices. The Early Childhood Oral health Impact Scale (ECOHIS) was used for assessment of oral health related quality of life. Mixed effects logistic regression was conducted with dmft and ECOHIS scores as outcomes and HIV-1 exposure status as the main exposure. Results: Forty-eight percent of HEU children and 60% of HUU had dmft>0. Corresponding figures for ECOHIS>0 were 12% of HEU and 22% of HUU. The crude analysis showed differences related to HIV-1 exposure in caries experience and oral health related quality of life. Mixed effect logistic regression analyses were not significant when adjusted for use of dental care and toothache. If caregivers’ DMFT>0, the adjusted odds ratio for caries experience (dmft>0) was 1.6 (95% CI: 1.0-2.8) while if dmft>0 the adjusted odds ratio for quality of life impacts (ECOHIS>0) was 4.6 (95% CI: 2.0-10.6). Conclusion: The prevalence of untreated caries in primary teeth and quality of life impacts was high in this study population. HIV-1 exposed-uninfected children were not more likely than HUU children to experience dental caries or have impaired oral health related quality of life. Given the global expansion of the HEU child population, the present findings indicating no adverse effect of pre- and post-natal HIV-1 exposure on caries in deciduous teeth are reassuring.

Abstract
Background: Depression is one of the most common psychiatric disorders in the older adult and one of the most common risk factors for suicide in the older adult. Studies show different and inconsistent prevalence rates in Iran. This study aims to determine the prevalence of severe depression in Iranian older adult through a meta-analysis approach. Methods: The present meta-analysis was conducted between January 2000-August 2019. Articles related to the subject matter were obtained by searching Scopus, Sciencedirect, SID, magiran, Barakat Knowledge Network System, Medline (PubMed), and Google Scholar databases. The heterogeneity of the studies was evaluated using I2 index and the data were analyzed in Comprehensive Meta-Analysis software. Results: In a study of 3948 individuals aged 50-90 years, the overall prevalence of severe depression in Iranian older adult was 8.2% (95% CI: 4.14-6.3%) based on meta-analysis. Also, in order to investigate the effects of potential factors (sample size and year of study) on the heterogeneity of severe depression in Iranian older adult, meta-regression was used. It was reported that the prevalence of severe depression in Iranian older adult decreased with increasing sample size and increasing years of the study, which is significantly different (P<0.05). Conclusion: Considering the high prevalence of severe depression in Iranian older adult, it is necessary for health policy makers to take effective control measures and periodic care for the older adult.

Abstract
Background: The programmed death-ligand 1 (PD-L1) pathway inhibits T-cell receptor-mediated production of IL-2 and T-cell proliferation and plays an important role in the immunosuppression of various types of cancers. An increasing number of studies have focused on the potential utilization of anti-PD-L1 therapy in gastrointestinal cancers. In this study, we aimed to analyze developments and emerging trends in studies of PD-L1 in gastrointestinal cancers from a bibliometric perspective. Methods: Manuscripts were retrieved from th Web of Science Core Collection (WOSCC) Database. CiteSpace, a bibliometric software, was used to identify landmark studies, key concepts, and various subtopics in this research area. Results: A total of 1325 manuscripts examining PD-L1 in gastrointestinal cancers were included. Manuscripts published in 2017 and 2018 accounted for almost half of the publications (44.2%, 586/1325). Combined with 31,960 references, the manuscripts on this topic constituted a complex co-citation network, and landmark papers were identified by indexes including citation in the network, betweenness centrality, and burstiness . Key concepts such as “Regulatory T cell,” “TIL,” and “Her2” were identified in the co-citation network for author keywords. Furthermore, several subtopics were identified during the process of “clustering” in colorectal, gastroesophageal, and hepatopancreatobiliary cancers, such as “predictive biomarkers”, “advanced cancers”, and “clinical efficacy”. Conclusions: Research on PD-L1 i n gastrointestinal cancers is a rapidly progressing area. More scientific findings are expected in the near future. Analysis and summarization from a bibliometric perspective not onlyidentify landmark manuscripts and hot-spot concepts but also indicate possible directions for future studies.

Abstract
Background Over the last few decades tick-borne diseases have emerged as an increasingly significant public health problem. The distribution and prevalence of zoonotic pathogens infecting ixodid ticks from Western Europe have been extensively examined. However, data on ticks and tick-borne pathogens in Eastern Europe, particularly Ukraine are scarce. The objective of the current study was, therefore, to investigate the prevalence rates of Anaplasma phagocytophilum , the Anaplasmataceae family, Rickettsia spp., Babesia spp., Bartonella spp., and Borrelia burgdorferi sensu lato in engorged and questing ixodid ticks collected from five administrative oblasts (regions) of Ukraine, namely Chernivtsi, Khmelnytskyi, Kyiv, Ternopil, and Vinnytsia.Methods The ticks were collected from both wild and domestic animals and from vegetation. Of 524 ixodid ticks collected, 3, 99, and 422 ticks were identified as Ixodes hexagonus , Ixodes ricinus, and Dermacentor reticulatus , respectively. DNA samples individually extracted from 168 questing and 354 engorged adult ticks were subjected to pathogen-specific PCR analyses.Results The mean prevalence rates in all I. ricinus and D. reticulatus ticks were, respectively: 10.3% (10/97) and 2.8% (12/422) for A. phagocytophilum ; 69.1% (67/97) and 52.1% (220/422) for the Anaplasmataceae family; 24.7% (24/97) and 27.7% (117/422) for Rickettsia spp.; 3.1% (3/97) and 1.4% (6/422) for Babesia spp.; and 9.3% (9/97) and 4.7% (20/422) for Bartonella spp. Overall, between the five cities, there was no significant difference in the prevalence rates of any of the pathogens for the respective ticks ( p >0.05). The prevalence of B. burgdorferi s.l. in the engorged and questing I. ricinus ticks varied from 26.7% and 0% to 44.4% and 14.3%, respectively, with no statistical significance identified between the five cities ( p >0.05).Conclusions In addition to reporting the updated data for Kyiv and Ternopil, this study is the first to provide the prevalence rates of the tick-borne pathogens for Chernivtsi, Khmelnytskyi, and Vinnytsia. This investigation is also the first to detect Ca. N. mikurensis in ixodid ticks from Ukraine. These new data will be useful for medical and veterinary practitioners as well as public health officials when diagnosing infections and when implementing measures to combat tick-borne diseases in Ukraine.
