Abstract

Background
High temperature is one of the major abiotic stresses in tomato and greatly reduces fruit yield and quality. Identifying high-temperature stress-responsive (HSR) genes and breeding heat-tolerant varieties is an effective way to address this issue. However, there are few reports on the fine mapping of heat-tolerance quantitative trait locus (QTL) and the identification of HSR genes in tomato. Here, we applied three heat tolerance-related physiological indexes, namely, relative electrical conductivity (REC), chlorophyll content (CC) and maximum photochemical quantum efficiency (Fv/Fm) of PSII (photosystem II), as well as the phenotypic index, the heat injury index (HII), and conventional QTL analysis combined with QTL-seq technology to comprehensively detect heat-tolerance QTLs in tomato seedlings. In addition, we integrated the QTL mapping results with RNA-seq to identify key HSR genes within the major QTLs.

Results
A total of five major QTLs were detected: qHII-1-1, qHII-1-2, qHII-1-3, qHII-2-1 and qCC-1-5 (qREC-1-3). qHII-1-1, qHII-1-2 and qHII-1-3 were located, respectively, in the intervals of 1.43, 1.17 and 1.19 Mb on chromosome 1, while the interval of qHII-2-1 was located in the intervals of 1.87 Mb on chromosome 2. The locations observed with conventional QTL mapping and QTL-seq were consistent. qCC-1-5 and qREC-1-3 for CC and REC, respectively, were located at the same position by conventional QTL mapping. Although qCC-1-5 was not detected in QTL-seq analysis, its phenotypic variation (16.48%) and positive additive effect (0.22) were the highest among all heat tolerance QTLs. To investigate the genes involved in heat tolerance within the major QTLs in tomato, RNA-seq analysis was performed, and four candidate genes (SlCathB2, SlGST, SlUBC5, and SlARG1) associated with heat tolerance were finally detected within the major QTLs by DEG analysis, qRT-PCR screening and biological function analysis.

Conclusions
In conclusion, this study demonstrated that the combination of conventional QTL mapping, QTL-seq analysis and RNA-seq can rapidly identify candidate genes within major QTLs for a complex trait of interest to replace the fine-mapping process, thus greatly shortening the breeding process and improving breeding efficiency. The results have important applications for the fine mapping and identification of HSR genes and breeding for improved thermotolerance.

Abstract

Background
Otoscopy alone has low sensitivity and specificity for acute otitis media (AOM). Otomicroscopy and pneumatic methods are superior to otoscopy. However, these methods require clinical skills. The use of different diagnostic methods for AOM differs between countries and has not been evaluated in Sweden since new guidelines were introduced in 2010. This study aimed to describe the extent of which diagnostic methods and written advice were used for AOM in children 1 to 12 years old.

Methods
In this cross-sectional study all general practitioners (GPs) and specialist trainees in primary care (STs) at 27 primary health care centres in Sweden were asked to complete a self-administrated questionnaire including diagnostic approach and the management of AOM; 75% (111/148) responded to the questionnaire. Outcome Measures: GPs versus STs and their gender, the use of otoscopy, pneumatic otoscopy, otomicroscopy, tympanometry and written advice. Logistic regressions were used to evaluate the association between GPs versus STs and their gender and the use of diagnostic methods and written advice.

Results
To diagnose AOM, 98% of the GPs and STs often or always used otoscopy, in addition to this 17% often or always used otomicroscopy, 18% pneumatic otoscopy and 11% tympanometry. Written advice to parents was provided often or always by 19% of the GPs and STs.
The GPs used otomicroscopy more often than STs, adjusted OR 4.9 (95% CI 1.5–17; p = 0.011). For the other diagnostic methods, no differences were found. Female GPs and STs provided written advice more often than male GPs and STs, OR 5.2 (95% CI, 1.6–17; p = 0.0061), adjusted for GP versus ST.

Conclusions
Otoscopy was by far the most commonly used method for the diagnosis of AOM. Female GPs and STs provided written advice more frequently than did their male colleagues. GPs used the significantly better method otomicroscopy more often than STs, therefore, it is important to emphasise teaching of practical skills in otomicroscopy in the specialist training programme for general practice. A correct diagnosis is important for avoiding potentially harmful antibiotic treatments, antimicrobial resistance and possible delay of other diagnoses.

Abstract

Background
The number of new rickettsial species are rapidly increasing, and increasing numbers of Rickettsia raoultii (R. raoultii) infection cases have been detected in humans. However, neurological abnormalities caused by R. raoultii are rarely reported, especially in northwestern China.

Case presentation
A 36-year-old Kazakh shepherd with an attached tick on part temporalis, presented with right eyelid droop, lethargy, fever, headache, fever (38.0–41.0 °C) and erythematous rash. The examination of cerebrospinal fluid (CSF) showed cerebrospinal pressure of 200 mm H2O, leukocyte count of 300.0 × 106/L, adenosine deaminase of 2.15 U/L, and total protein concentration of 0.93 g/L. The diagnosis of R. raoultii infection was confirmed by six genetic markers, and semi-quantified by enzyme-linked immunosorbent assay for rickettsial antigen. The patient gradually recovered after treatment with doxycycline and ceftriaxone. R. raoultii DNA was found both in a tick detached from this patient and in 0.18% (2/1107) of blood samples collected from local shepherds.

Conclusions
This is the first reported case with neurological abnormalities caused by R. raoultii in northwestern China. It is vital to detect rickettsial agents both in blood and CSF for tick bite patients with neurological abnormalities. Public health workers and physicians should pay attention to neurological abnormalities caused by Rickettsia.

Abstract

Background
The accuracy of different laboratory tests for diagnosis of diabetes mellitus (DM) and prediabetes (preDM) in populations exposed to tuberculosis (TB) remains poorly understood. Here, we examined the prevalence of DM and preDM in TB affected people in Lima, Peru.

Methods
A prospective cohort study of patients affected TB and their household contacts (HHC), was conducted between February and November 2017 in Lima, Peru. Fasting plasma glucose (FPG), HbA1c and oral glucose tolerance test (OGTT) were used to detect DM and preDM in a prospective cohort of TB patients (n = 136) and household contacts (n = 138). Diagnostic performance of the laboratory tests was analyzed. Potential effects of sociodemographic and clinical factors on detection of dysglycemia were analyzed.

Results
In TB patients, prevalence of DM and preDM was 13.97 and 30.88% respectively. Lower prevalence of both DM (6.52%) and preDM (28.99%) were observed in contacts. FPG, HbA1c and OGTT had poor agreement in detection of preDM in either TB cases or contacts. TB-DM patients had substantially lower hemoglobin levels, which resulted in low accuracy of HbA1c-based diagnosis. Classic sociodemographic and clinical characteristics were not different between TB patients with or without dysglycemia.

Conclusion
High prevalence of DM and preDM was found in both TB patients and contacts in Lima. Anemia was strongly associated with TB-DM, which directly affected the diagnostic performance of HbA1c in such population.

Abstract

Background
In Nepal, cases of Cholera occur annually either as sporadic or as outbreaks claiming the lives of many in rural areas. The present study is a laboratory based surveillance which aims to analyze the changing epidemiology and antimicrobial susceptibility trend of V. cholerae strains isolated or referred to National Public Health Laboratory (NPHL) over a period of 11 years (2006–2016).

Methods
Specimens of fresh stool /rectal swab either received at sentinel sites or NPHL were processed following standard microbiological techniques. Suspected colonies on selective medium were identified using routine biochemical tests and confirmed by serotyping. Antimicrobial susceptibility testing was performed following Kirby Baeur disc diffusion method.

Results
Of the 836 confirmed isolates, 87% (728/836) were V.cholerae O1 Ogawa,12% (103/836) were V.cholerae O1 Inaba and only 6 isolates were V.cholerae O1 Hikojima. In 2006 all the Vibrio isolates were of Inaba serotype, followed by all 3 serotypes during 2007.During 2008–2014 only Ogawa serotype was isolated while few cases of Inaba again surfaced in 2015. Resistance to ampicillin decreased from 93% in 2006 to 18% by 2010 and again raised to 100% by 2016.Cotrimoxazole resistance remained at constant range (77–100%).Nalidixic acid resistance was 100% since 2006.Ciprofloxacin and tetracycline resistance emerged in 2007, reached a peak during 2010–2012 and declined to 0 by 2016.Susceptibility to Furazolidone has re-emerged.63.6% of the isolates were Multi drug resistant.

Conclusion
With changing epidemiology and antibiogram of V.cholerae in Nepal, the present study reflects the importance of continuous monitoring, which could be used by policy makers and health professionals for better management of outbreaks. Decline in tetracycline and ciprofloxacin resistance along with emerging sensitivity to furazolidone shows that these drugs could make an effective comeback in future.

Abstract

Background
Although immunoglobulin A nephropathy (IgAN) is associated with an increased risk of renal allograft failure, evidences for its treatment, including renin-angiotensin-aldosterone system blockade (RAASB) usage, remain limited.

Methods
In this bi-center retrospective cohort study, we included patients who were recently diagnosed with IgAN through allograft biopsies. We identified their 6-month antihypertensive medication prescriptions and investigated the association between the medication types, albuminuria changes, and risk of 5-year death-censored-graft-failure (DCGF). The mixed effect model and cox regression analysis were used.

Results
A total of 464 allograft IgAN patients were included: 272, 38, 33, and 121 patients in the no antihypertensive medication, single agent RAASB, single agent beta blocker (BB)/calcium channel blocker (CCB), and combination therapy groups, respectively. High-degree albuminuria after 6 months of allograft IgAN diagnosis was an important prognostic parameter and a partial mediator for the association between the subgroups and 5-year DCGF. The usage of single RAASB was associated with decrement of albuminuria from allograft IgAN diagnosis (P for interaction = 0.03). The single BB/CCB group demonstrated significantly worse prognosis than the single RAASB group (adjusted hazard ratio, 2.76 [1.09–6.98]; P = 0.03).

Conclusions
In conclusion, RAASB may be beneficial for graft prognosis in early allograft IgAN patients who require single antihypertensive medication therapy, by means of reducing albuminuria. Further investigation of treatment strategy in allograft IgAN is warranted.

Abstract
Following definitive chemoradiation for anal squamous cell carcinoma (ASCC), patients face a variety of chronic issues including: bowel dysfunction, accelerated bone loss, sexual dysfunction, and psychosocial distress. The increasing incidence of this disease, high cure rates, and significant long-term sequelae warrant increased focus on optimal survivorship care following definitive chemoradiation. In order to establish our survivorship care model for ASCC patients, a multi-disciplinary team of experts performed a comprehensive literature review and summarized best practices for the multi-disciplinary management of this unique patient population. We reviewed principle domains of our survivorship approach: (1) management of chronic toxicities; (2) sexual health; (3) HIV management in affected patients; (4) psychosocial wellbeing; and (5) surveillance for disease recurrence and survivorship care delivery. We provide recommendations for the optimization of survivorship care for ASCC patients can through a multi-disciplinary approach that supports physical and psychological wellness.

Abstract

Background
One of the greatest effects of the financial crisis in Spain has been the enormous increase in the number of evictions. Several studies have shown the association of evictions with different aspects of the physical and mental health. Furthermore, evictions have been associated with an increased risk of suicide. Our objective was to evaluate the risk of suicide among victims of eviction and investigate whether it is associated with specific characteristics of households and interviewees, the eviction process and social support, and health needs.

Methods
A total of 205 participants from households threatened with eviction in Granada, Spain, and 673 being the total number of members of these households, were interviewed in one-on-one sessions between April 2013 and May 2014. Through a questionnaire, information was obtained on physical and mental health, characteristics of their eviction process and support networks, and the use of health services.

Results
Almost half of the sample (46.7%) were at low (11.8%), moderate (16.9%), or high suicide risk (17.9%). Household and interviewee features had a limited association with suicide risk. On the contrary, the risk of suicide is greater with a longer exposure to the eviction process. In addition, threatening phone calls from banks increased significantly the risk of suicide, especially among men. Suicide risk was also associated with low social support, especially among women. Interviewees at risk of suicide received more help from nongovernmental organizations than those who were not at risk. In interviewees at risk, the main unmet needs were emotional and psychological help, especially in men. A high percentage of those at risk of suicide declare having large unmeet health needs. Finally, there was a tendency among the evicted at risk of suicide to visit emergency room and primary care more often than those not at risk, especially among women.

Conclusions
To our knowledge, this is the first study showing that when banks adopt a threatening attitude, suicide risk increases among the evicted. As hypothesized, when the evicted felt socially supported, suicide risk decreased. Emotional help was the main mediator of suicide risk and the main unmet need, especially among men.

AbstractBackgroundMedia advocacy plays an important role in public health initiatives, as it can provide vital information to target populations, policy makers, or other relevant stakeholders. Unfortunately, little is currently known about the use of media advocacy to promote occupational safety and health programs. This study explores media coverage related to the Rollover Protection Structure (ROPS) Rebate Programs, which were designed to encourage the use of rollover protection on agricultural tractors, thus reducing the risk of tractor overturn fatalities. The Program’s portrayal in the media, as well as the role that the media has played in implementing and sustaining these Programs.MethodsMedia articles pertaining to any of the state-based or National ROPS Rebate Programs and published between November 1, 2006 and October 31, 2018 were included for review. Discourse analysis was used to understand the messages portrayed by the media and how those messages shaped the outcomes of the ROPS Rebate Programs.ResultsDuring the study period, 212 unique articles were published about the ROPS Rebate Programs. While these articles all portrayed the ROPS Rebate Programs in a largely positive light, they were used at different stages, from pre-implementation through sustainment of the ROPS Rebate Programs, and to different extents.ConclusionsMedia articles have played an important role in implementing and sustaining the ROPS Rebate Programs. Based on the results of this study, more robust and continuous media coverage are important for the longevity and success of public health programs.

AbstractBackgroundLower health literacy (HL) has been known to be involved in a range of common mental and physical disorders among adolescent students. Ample studies indicated low HL is associated with a series of chronic diseases even psychological diseases, nevertheless, little is known about this relationship among adolescents. In this context, the study aimed to examine associations between psychosomatic symptoms (physical and psychological symptoms) and HL in junior and senior high school students in China, and to provide guidance for improving the physical and mental health in Chinese adolescents.MethodsA total of 22,628 junior and high school students in China were enrolled in this study. HL and psychosomatic symptoms were measured by self-report validated questionnaires. Multiple linear regression analyses were conducted to examine the associations between six sub-scales of HL and physical / psychological symptoms.ResultsMultiple linear regression analysis demonstrated that the sub-scales of HL showed a significantly negative association with physical symptoms and psychological symptoms (P <  0.05 for each). Physical symptoms was most strongly associated with IR (β = − 0.134), followed by SM (β = − 0.093), DB (β = − 0.059), SA (β = − 0.058) and PA (β = − 0.054). No statistically significant difference was found between HA and physical symptoms (P > 0.05). Meanwhile, psychological symptoms were most strongly associated with IR (β = − 0.160), followed by SA (β = − 0.129), SM (β = − 0.069), DB (β = − 0.031), HA (β = − 0.026) and PA (β = − 0.021).ConclusionThese results indicated the importance of identifying the association of HL with physical and psychological symptoms, and provided the evidence that lower HL may serve as a critical and independent risk factor for poor health outcomes. Meanwhile, to maintain students’ desirable healthy status public health efforts for enhancing their HL level are urgently needed in adolescents.

AbstractBackgroundThe incidence of cardiac implantable electronic device infection (CIEDI) is low and usually belongs to the typical imbalanced dataset. We sought to describe our experience on the management of the imbalanced CIEDI dataset.MethodsDatabase from two centers of patients undergoing device implantation from 2001 to 2016 were reviewed retrospectively. Re-sampling technique was used to improve the classifier accuracy.ResultsCIEDI was identified in 28 out of 4959 procedures (0.56%); a high imbalance existed in the sizes of the patient profiles. In univariate analyses, replacement procedure and male were significantly associated with an increase in CIEDI: (53.6% vs. 23.4, 0.8% vs. 0.3%,P < 0.01). Multivariate logistic regression analysis showed that gender (odds ratio, OR = 3.503), age (OR = 1.032), replacement procedure (OR = 3.503), and use of antibiotics (OR = 0.250) remained as independent predictors of CIEDI (allP < 0.05) after adjustment for diabetes, post-operation fever, and device style, device company.There were 616 under-sampled cases and 123 over-sampled cases in the analyzed cohort after re-sampling. The re-sampling and bootstrap results were robust and largely like the analysis results prior re-sampling method, while use of antibiotics lost the predicting capacity for CIEDI after re-sampling technique (P > 0.05).ConclusionThe application of re-sampling techniques can generate useful synthetic samples for the classification of imbalanced data and improve the accuracy of predicting efficacy of CIEDI. The peri-operative assessment should be intensified in male and aged patients as well as patients receiving replacement procedures for the risk of CIEDI.
