Abstract
Objective: To understand the prevalence of chronic cough, chronic expectoration and dyspnea and related factors in residents aged ≥40 years in China, and provide basic data for the prevention and control of chronic respiratory diseases. Methods: Data were from 2014-2015 chronic obstructive pulmonary disease surveillance in China. The information about chronic respiratory symptoms were collected by face-to-face interview. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms and their 95%CI were estimated with complex sampling weights. Results: A total of 75 082 subjects were included in the analysis. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in the Chinese aged ≥40 years were 3.75% (95%CI: 3.38%-4.11%), 5.83% (95%CI: 5.40%-6.26%), 2.45% (95%CI: 2.02%-2.87%) and 8.93% (95%CI: 8.25%-9.62%), respectively. The prevalence rates of chronic cough, chronic expectoration, dyspnea and chronic respiratory symptoms in patients with chronic respiratory diseases were relatively higher, which were 10.27%, 13.85%, 6.43%, 20.72% respectively. Multivariate logistic regression analysis showed that age, region, education level, occupation, BMI, family history of respiratory diseases, history of severe respiratory infections in childhood, exposure to dust or chemicals in workplace and smoking status affected the prevalence of chronic cough, chronic expectoration and dyspnea. The prevalence of the three types of chronic respiratory symptoms increased significantly with age, which were higher in western region, smokers and underweight/obese subjects. The three prevalence rates mentioned above were higher in those with a history of severe respiratory infection in childhood, those exposed to biomass fuel in household, and those exposed to dust or chemicals in workplace. Conclusions: The prevalence rate of chronic respiratory symptoms was high in residents aged ≥40 years in China. Many factors affected the prevalence of chronic respiratory symptoms. Comprehensive prevention and control measures targeting risk factors should be taken to reduce the burden of chronic respiratory diseases.

Abstract
Background Prurigo nodularis (PN) is a highly pruritic, chronic dermatosis and difficult to treat. PN lesions are characterized by existence of many hyperkeratotic, erosive papules and nodules. However, the pathogenesis of PN still remains unelucidated. Aim To clarify the keratin role in the epidermis hyperproliferation, the keratin expression pattern in the PN lesional skin. Methods In this study, we enrolled 24 patients with PN and 9 healthy control volunteers. K1/K10, K5/K14, K6/K16/K17 expression pattern were investigated by using immunohistochemical staining. Results The lesional skin consists of the thickened spinous layers, in which active cell division was found. K5/K14 were upregulated in PN lesional epidermis, the staining signal localized in the basal layer and lower suprabasal layers. Hyperproliferation‐associated K6 was found in all layers of epidermal lesional skin, especially in the spinous layers. In contrast, K16 was only detected in the basal and lower suprabasal layers, K17 was observed in the basal and spinous layers. Terminal differential keratins K1/K10 were upregulated, detected in the pan‐epidermis, but spared in the basal and low suprabasal layers. Conclusion The keratinocytes enter an alternative differentiation pathway, which are responsible for the activated keratinocyte phenotype, abnormal keratins expression potentially contributes to the keratinocytes proliferation, subsequently lead to increased lesional skin epidermis thickness, hyperkeratiosis and alteration of skin barrier properties.

Abstract
OTU domain-containing ubiquitin aldehyde-binding proteins 1 (OTUB1) is the most important element of the deubiquitinase OTU superfamily, which has been identified as an essential regulator of diverse physiological processes, such as DNA damage repair and cytokines secretion. Recently, we found that the pro-carcinogenesis role of OTUB1 and the relationship between OTUB1 and immune response have gradually become the research hot-spot. OTUB1 regulates NK/CD8 T cell activation, autoimmune diseases, PD-L1 mediated immune evasion, viral or bacterial infection related immune response and the occurrence and progression of various cancers via deubiquitinating and stabilizing related proteins. This review provides a comprehensive description about the role and regulatory axis of OTUB1. We can explore the balance between immune response and defense via regulating the level of OTUB1, and targeting OTUB1 might restrain the progression of cancers. This review highlights the experimental evidence that OTUB1 is a feasible and potential therapeutic target against various cancers progression and immune diseases or disorder.

Abstract
OBJECTIVE To estimate the social and economic burden of Downs syndrome for patients and their families residing in Changsha, China. METHODS An 160-item self-administered questionnaire was designed and distributed to the primary caregivers of the patients in March 2020. A total of 81 eligible participants had completed the questionnaire, among which 20 were excluded for incomplete data. A patient perspective was taken to estimate the economic burden of the disease. The social impact of the disease on the patient's family was evaluated through questions adapted from the Stanford Psychological Wellbeing (PWB) Scale. RESULTS The estimated life-course cost of a Downs syndrome patient in Changsha is 4 985 659 RMB, with the patient and caregiver's loss of income taking the greater proportion. In addition, as the majority of the patients' primary caregivers, female caregivers experienced not only considerable financial hardship caused by the care provision, but also a significant amount of psychological pressure and social discrimination. CONCLUSION Increased level of social welfare for the patients and social support for their female caregivers are essential for reducing economic burden and improving their quality of life in the area. In addition, prenatal screening and diagnosis for Downs syndrome are important for reducing both the social and economic burden of the disease by preventing its occurrence.

Abstract
Anesthesia may induce neuronal tau phosphorylation and neurotoxicity in the developing brain. Apolipoprotein E (ApoE) may play a protective role in neuronal activity and injury repair, whereas its 18-kDa fragments are reported to induce neurodegeneration and neuroinflammation in Alzheimer's disease patients. We aimed to test the hypothesis that differences in 18-kDa ApoE fragment levels, but not full-length ApoE, in primary neurons contribute to differences in tau phosphorylation and neuroinflammation with or without sevoflurane administration. Neurons extracted from wild-type (WT), ApoE knockout (ApoE-KO), and ApoE ε3-and ε2-targeted replacement (ApoE ε3, ApoE ε2) mice were divided into control and sevoflurane groups. Neurons in the sevoflurane group were treated with 21% O2, 5% CO2, and 4.1% sevoflurane, whereas those in the control group were treated with 21% O2 and 5% CO2 only on day 5 of neuronal culture. ApoE mRNA, full-length ApoE, 18-kDa ApoE fragments, Tau-PS202/PT205 (AT8), Tau-PSer396/404 (PHF1), tumor necrosis factor (TNF)-α, and interleukin (IL)-6 and IL-1β levels were measured. The data showed that sevoflurane-induced AT8 and PHF1 increases, and TNF-α, IL-6, and IL-1β increases in WT or ApoE ε3 neurons (both expressing full-length and 18-kDa fragmented ApoE) could be mitigated in ApoE ε2 (only expressing full-length ApoE), but not in ApoE-KO neurons, indicating that differences in 18-kDa ApoE fragments, but not full-length ApoE, in primary mouse neurons contributed to differences in tau phosphorylation and neuroinflammation with or without 4.1% sevoflurane administration.

Abstract
The introduction of N2 -fixing species into a Eucalyptus plantation resulted in a successful planting system. It is essential to understand the contribution of nitrogen (N) competition and photosynthetic efficiency to plant dry matter yield to shed more light on the growth mechanism of the Eucalyptus/legume system. We compared N competition, photosynthesis and dry matter yield of Eucalyptus urophylla × E. grandis and the N2 -fixing tree species Dalbergia odorifera in intercropping and monoculture systems under different N levels. The photosynthesis of E. urophylla × E. grandis was improved, while that of D. odorifera was inhibited in the intercropping system. Intercropped E. urophylla × E. grandis increased the N utilization and the dry matter yield by 6.57-48.46% and 7.59-97.26%, and decreased those of D. odorifera by 10.21-30.33% and 0.48-13.19%, respectively. Furthermore, N application enhanced the competitive ability of E. urophylla × E. grandis relative to D. odorifera and changed the N contents and chlorophyll synthesis to optimize the photosynthetic structure of both species. Our results reveal Eucalyptus for photosynthesis, N absorption and increasing the growth benefit from the introduction of N2 -fixing species, which hence can be considered to be an effective sustainable management option of Eucalyptus plantations.

Abstract
OBJECTIVES The study aimed to evaluate the association of dietary iron intake with incident dementia and brain iron deposition. DESIGN/SETTING/PARTICIPANTS We included dementia-free participants from the UK Biobank who completed at least one 24-hour dietary recall at study baseline (2009-2012) and were followed up to 2021. Incident dementia was determined through linkage to medical records and death registries. Brain MRI was conducted in a subgroup of participants since 2014, with T2* measurements being used as indicators of brain iron deposition. MEASUREMENTS Cox proportional hazard models were used to assess the associations of high (top quintile) and low (bottom quintile) versus medium (quintile 2 to 4) level of dietary iron intake with incident dementia, respectively. Linear regression was applied to assess the relations between dietary iron intake and brain T2* measurements. RESULTS During follow-up (mean = 9.5 years), a total of 1,454 participants (650 women and 804 men) developed dementia among 191,694 participants (55.0% female; mean age, 56.2 years). When adjusted for sociodemographic, lifestyle, and other dietary factors, participants with low dietary iron intake (< 10.05 mg/day) had a significantly higher dementia risk (hazard ratio [HR], 1.50, 95% confidence interval [CI], 1.19-1.89), while the relation for high intake (> 16.92 mg/day) was non-significant (HR, 1.16, 95% CI, 0.92-1.46). A significant gender difference (P-interaction < 0.001) was observed, with a U-shaped association in male participants (HR for low vs. medium, 1.56, 95% CI, 1.14-2.13; HR for high vs. medium, 1.39, 95% CI, 1.03 - 1.88; P-nonlinearity < 0.001) and no significant association in females, regardless of their menopause status. In general, dietary iron intake was not related to T2* measurements of iron deposition in most brain regions. CONCLUSION Our findings suggested a U-shape relationship between dietary iron intake and risk of dementia among males, but not females.

Abstract
BACKGROUND AND AIMS This study assessed the prognostic value of LCR in patients with cancer-associated malnutrition (CAM). Systemic inflammatory markers, particularly the lymphocyte-to-C-reactive protein ratio (LCR), are related to the survival of patients with CAM. The present retrospective analysis based on a prospective multicenter cohort study, which involved 1,437 hospitalized patients with CAM. METHODS The area under the receiver operating characteristic curve (AUC) of ten inflammatory indicators-LCR, advanced lung cancer inflammation index, neutrophil-to-lymphocyte ratio, prognostic nutritional index, modified Glasgow prognostic score, systemic immune-inflammation index, albumin-to-globulin ratio, LCR score, glucose-to-lymphocyte ratio, and platelet-to-lymphocyte ratio-were constructed. Nutritional status, blood markers, and quality of life (QoL) were evaluated within 48 h of admission. The overall survival (OS) was evaluated from September 1 to December 29, 2021. RESULTS A total of 1,431 cancer patients diagnosed with malnutrition based on the Global Leadership Initiative on Malnutrition (GLIM) criteria. Male patients were 62.8% of all, and the mean age was 60.66 years old. The AUC of LCR was higher than that of other inflammatory markers. The restricted cubic spline (RCS) of the Hazard ratios (HRs) showed an inverse L-shaped relationship with LCR. In addition, patients with low LCR had significantly poorer OS than those with high LCR. The addition of LCR to the model increased the predictive ability of 1-year mortality (AUC increase of 0.036), 3-year mortality (AUC increase of 0.038), and 5-year mortality (AUC increase of 0.031). CONCLUSIONS Assessing the LCR can help the medical staff identify cancer patients with nutritional deficiency at high risk of oncological outcomes and develop individualized therapeutic strategies.

Abstract
The relationship between the in-stent neoatherosclerosis (ISNA) formation and the plaque's characteristic changes in the non-culprit lesion is unclear. We aim to investigate the plaque characteristics changes at non-culprit lesions between patients with ISNA and without ISNA formation at 1-year follow-up. We retrospectively enrolled patients who had DES implantation in de novo lesion and underwent immediately after stenting and 1-year follow-up optical coherence tomography (OCT) examination. OCT-defined ISNA was defined as the presence of lipid-laden neointima or calcification within the culprit stent with a longitudinal extension of ≥1 mm. Non-culprit lesions were divided into two groups: ISNA group (with ISNA) and non-ISNA group (without ISNA). Plaque characteristics of non-culprit lesions were evaluated at baseline and 1-year follow-up. In total, 89 patients with 89 non-culprit lesions (ISNA: n = 37; non-ISNA: n = 52) were included in the analyses. The lesions in the ISNA group show a smaller minimum lumen area compared to the non-ISNA group at 1-year follow-up (2.57 ± 1.08 mm2 versus 3.20 ± 1.62 mm2, p = 0.044). The lesions of the ISNA group show a significant decrease in minimum lumen area changes percent (-7.25% versus 6.46%, p = 0.039). And there are more lesions with minimum lumen area (64.9% versus 38.5%, p = 0.014) and minimum lumen diameter (64.9% versus 40.4%, p = 0.023) decrease in the ISNA group. Furthermore, the lesions in ISNA group have more plaques with lipid core length increase (25.0% versus 10.0%, p = 0.040), more plaques with FCT decrease (50.0% versus 74.0%, p = 0.027) and less TCFA change to non-TCFA (33.3% versus 87.5%, p = 0.010). The plaque characteristic changes in non-culprit lesions are closely related to ISNA formation. The ISNA formation may accompany by a tardier plaque stabilization process in non-culprit lesions.

Abstract
1. This study investigated the effects of dietary betaine supplementation on growth performance, meat quality, muscle fatty acid composition and antioxidant ability in slow-growing broiler chickens.2. In total, 400, one-day-old female Xueshan broiler chicks were randomly divided into five groups with eight replicates of ten chickens each for 102 d. Broilers were fed a basal diet supplemented with 0, 125, 250, 500 or 1,000 mg/kg betaine.3. Broilers fed betaine had better feed conversion efficiency and weight gain (P < 0.05) and increased meat redness and yellowness 24 h after slaughter. Supplementation linearly decreased cooking loss and drip loss from breast muscle (P < 0.05). Muscular resilience was improved and tenderness increased (P < 0.05). Intra-muscular saturated fatty acids decreased, while total monounsaturated fatty acids and polyunsaturated fatty acids increased (P < 0.05). Betaine increased activities of glutathione peroxidase (GPx) and total superoxide dismutase (SOD), glutathione (GSH) level, ratio of reduced glutathione/oxidised glutathione, and activity of scavenging hydroxyl radicals. It increased the activity of total antioxidant capacity (T-AOC) in the breast muscle (P < 0.05). Moreover, supplementation up-regulated (P < 0.05) mRNA expression levels of blood and antioxidant markers.4. In conclusion, 1000 mg/kg betaine can be recommended as a supplement for slow-growing, Xueshan chicken.

Abstract
The Cephalotaxus genus is well-known owing to the numerous complex, biologically relevant natural products that can be obtained from its constituent species. The successful identification of various Cephalotaxus alkaloids and natural, structurally diverse cephalotane diterpenoids that exhibit antitumor activities and excellent pharmacological properties has encouraged the discovery of previously undescribed compounds from this genus. The present review summarizes the different strategies for the total synthesis of cephalotane diterpenoids as well as their diverse chemical structures, antitumor activities, structure-activity relationships (SARs), and biosynthetic pathways.

Abstract
Objective: To validate the accuracy and consistency of a previously established prediction model for the occurrence of hyperkalemia in non-dialytic chronic kidney disease (CKD) patients. Methods: All patients diagnosed with CKD from Outpatient Department of Shanghai Changzheng Hospital during the 4th quarter of 2020 were recruited. Demographic data, clinical characteristics and prediction model-related parameters of the patients were collected and analyzed. Receiver operating characteristic (ROC) curve was drawn to evaluate the effectiveness of the model, and the specificity and sensitivity were calculated based on the cut-off value of 4 obtained from the previous model. The improved Hanley method was used to compare the area under the curve (AUC) between the previously established model and current validation dataset. The calibration curve was drawn to verify the model calibration degree. Results: A total of 434 patients diagnosed with non-dialytic CKD were enrolled, among whom 233 were males and 201 were females, with an average age of (55±16) years. According to the measured serum potassium values, the prevalence of hyperkalemia was 7.6%. And 33 patients were allocated to the hyperkalemia group and 401 patients were to the normal potassium group. There was no significant difference in age and sex between the two groups (both P>0.05). A combination of hyperkalemia and heart failure (27.3% vs 3.7%, P<0.001), diabetes (42.4% vs 19.7%, P=0.002), and acidosis (51.5% vs 7.0%, P<0.001) were more frequently in the hyperkalemia group, compared with the normal serum potassium group. Patients in the hyperkalemia group were more likely to have a past history of serum potassium ≥5.0 mmol/L (48.5% vs 2.5%, P<0.001). For the drugs that could increase serum potassium levels, there was a significant correlation between Chinese herbal medicine and the occurrence of hyperkalemia, while renin-angiotensin-aldosterone system inhibitor (RAASi) and potassium supplementation showed no significant difference between the two groups. The results of ROC curve analysis showed that the AUC was 0.914, with the sensitivity of 84.8% and the specificity of 79.8% with the cut-off value of 4. The difference of AUC between the previously established risk assessment model of hyperkalemia in patients with non-dialytic CKD and current validation dataset was not statistically significant (Z=1.924, P=0.054), indicating the good accuracy and consistency of the prediction model. In the calibration curve, when the predicted risk of patients was below 0.4 or above 0.6, the prediction effect of the model was better. Conclusion: The previously-constructed hyperkalemia prediction model in non-dialytic CKD patients had good accuracy and consistency, and could be used to evaluate the risk of hyperkalemia in all stages of non-dialytic CKD patients.

Abstract
Berberine is an extract derived from Chinese herbs with pleiotropic cardiovascular protective effects. However, the underlying mechanism remains unclear because of its poor bioavailability. Herin, we aimed to investigate whether berberine affects choline diet-induced arterial thrombosis and explore the potential mechanism. Ultrasound and optical coherence tomography were used to assess the potential risk of artery thrombosis in vivo. The plasma concentrations of trimethylamine N-oxide (TMAO) and trimethylamine (TMA) were quantified with mass spectrometry. Enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qPCR) were utilized to detect the levels of microbial TMA-lyase choline utilization C (CutC) in faeces. Gut microbiota analysis was performed with 16S rRNA gene sequencing. For in vitro studies, platelet aggregometry, intracellular Ca2+ measurement, ATP release assay, flow cytometry and Western blot were applied to identify the effects of TMAO on platelets. Berberine treatment significantly decreased the CutC levels in the caecal contents, reduced choline diet-induced TMA and TMAO production, and subsequently, reduced the arterial thrombosis potential risk. Berberine administration remodelled the structure of gut microbiota in rats and increased the levels of the genus Lactobacillus. Finally, TMAO enhanced platelet reactivity to collagen by promoting the phosphorylation levels of extracellular signal-regulated kinase 1/2 (ERK1/2) and Jun N-terminal kinase (JNK) in platelets. These results demonstrate that berberine attenuates the risk of choline diet-induced arterial thrombosis by changing the gut microbial composition and reducing TMAO generation.

Abstract
Objective: To understand the infection status of HCV and Treponema pallidum (TP) in HIV/AIDS cases in Yunnan province,and identify the risk factors. Methods: Between January 1 and June 30 in 2020,a cross-sectional survey was conducted in Yunnan. Two enzyme-linked immunosorbent assay (ELISA) kits were used to detect anti-HCV, the positive results of both two kits indicated HCV infection. ELISA and syphilis toluidine red untreated serum test were applied to identify TP infection. Both Excel 2016 and SPSS 22.0 software were used for statistical analysis, and logistic regression model was conducted to identify the relevant factors of HCV and TP infection. Results: A total of 5 922 HIV/AIDS cases were included in this study, the infection rates of HCV and TP were 6.5% (383/5 922) and 5.8% (344/5 922) respectively. The co-infection rate of HCV and TP was 0.4% (22/5 922). The risk for HCV infection in HIV/AIDS cases was higher in younger age groups compared with age group ≥50 years (15-19:aOR=3.53;20-29:aOR=3.02;30-39:aOR=2.91;40-49:aOR=3.61), in males than in females (aOR=2.31), in the married and unmarried than in the divorced or widowed (married:aOR=1.61;unmarried:aOR=1.63), in other ethnic groups than in Han ethnic group (aOR=1.70), in people with lower education level than in people with education level of college and above (primary school degree and below:aOR=4.69;middle school:aOR=3.96), in people living in the central and western Yunnan than in people living in eastern Yunnan (central Yunnan:aOR=2.46; western Yunnan:aOR=7.08), in injection drug users than in MSM (aOR=131.08). The risk of TP infection in HIV/AIDS cases was higher in people with education level of college and primary school than in middle school degree (primary school and below:aOR=1.73;college and above:aOR=1.77), in people with other occupations than in farmers (aOR=1.39), in people living in eastern Yunnan than in people living in western Yunnan (aOR=1.75); in MSM than in people with heterosex (aOR=9.75). Conclusions: A certain proportion of HIV/AIDS cases reported between January and June in 2020 in Yunnan were co-infected with HCV and TP, many factors were associated with the co-infection. It is suggested to strengthen HCV and TP tests in HIV/AIDS cases and conduct active treatment of the co-infection.

C1q/TNF-Related Protein 9 Attenuates Atherosclerosis by Inhibiting Hyperglycemia-Induced Endothelial Cell Senescence Through the AMPKα/KLF4 Signaling Pathway. Front Pharmacol 2021; 12:758792.

Abstract
Hyperglycemia-induced endothelial cell senescence has been widely reported to be involved in the pathogenesis of type 2 diabetes mellitus‒accelerated atherosclerosis. Thus, understanding the underlying mechanisms and identifying potential therapeutic targets for endothelial cell senescence are valuable for attenuating atherosclerosis progression. C1q/tumor necrosis factor-related protein 9 (CTRP9), an emerging potential cardiokine, exerts a significant protective effect with respect to atherosclerosis, particularly in endothelial cells. However, the exact mechanism by which CTRP9 prevents endothelial cells from hyperglycemia-induced senescence remains unclear. This study aimed to investigate the effects of CTRP9 on hyperglycemia-induced endothelial cell senescence and atherosclerotic plaque formation in diabetic apolipoprotein E knockout (ApoE KO) mice. Human umbilical vein endothelial cells (HUVECs) were cultured in normal glucose (5.5 mM) and high glucose (40 mM) with or without recombinant human CTRP9 protein (3 μg/ml) for 48 h. Purified lentiviruses overexpressing CTRP9 (Lv-CTRP9) and control vectors containing green fluorescent protein (Lv-GFP) were injected via the tail vein into streptozotocin-induced diabetic ApoE KO mice. Results revealed that exposure of HUVECs to HG significantly increased the expression of Krüppel-like factor 4 (KLF4) and cyclin-dependent kinase inhibitor p21 (p21) and decreased that of telomerase reverse transcriptase (TERT). Treatment with recombinant human CTRP9 protein protected HUVECs from HG-induced premature senescence and dysfunction. CTRP9 promoted the phosphorylation of AMP-activated kinase (AMPK), attenuated the expression of KLF4 and p21 induced by HG, and increased the expression of TERT in HUVECs. Furthermore, in the background of AMPKα knockdown or KLF4 activation, the protective effects of CTRP9 were abolished. In-vivo experiments showed that the overexpression of CTRP9 inhibited vascular senescence and reduced atherosclerotic plaque formation in ApoE KO mice with diabetes. In conclusion, we demonstrate that KLF4 upregulation plays a crucial role in HG-induced endothelial senescence. This anti-atherosclerotic effect of CTRP9 may be partly attributed to the inhibition of HG-induced endothelial senescence through an AMPKα/KLF4-dependent mechanism, suggesting that CTRP9 could benefit further therapeutic approaches for type 2 diabetes mellitus‒accelerated atherosclerosis.

Abstract
Porcine reproductive and respiratory syndrome virus (PRRSV) has been one of the major health-related concerns in the swine production industry. Through its rapid transmission and mutation, the simultaneous circulation of multiple PRRSV strains can be a challenge in PRRSV diagnostic, control and surveillance. The objective of this longitudinal study was to describe the temporal detection of PRRSV in swine farms with different production types and PRRS management strategies. Tonsil scraping (n = 344) samples were collected from three breeding and two growing herds for approximately one year. In addition, processing fluids (n = 216) were obtained from piglet processing batches within the three breeding farms while pen-based oral fluids (n = 125) were collected in the two growing pig farms. Viral RNA extraction and reverse-transcription quantitative PCR (RT-qPCR) were conducted for all samples. The sample positivity threshold was set at quantification cycle (Cq) of ≤ 37. Statistical analyses were performed using generalized linear modelling and post hoc pairwise comparisons with Bonferroni adjustments using R statistical software. The results suggested a higher probability of detection in processing fluids compared to tonsil scraping specimens [odds ratio (OR) = 3.86; p = .096] in breeding farms whereas oral fluids were outperformed by tonsil scrapings (OR = 0.26; p < .01) in growing pig farms. The results described herein may lead to an improvement in PRRSV diagnostic and surveillance by selecting proper specimens.

Abstract
BACKGROUND: Programmatic management of TB infection is a critical component of the WHO End TB Strategy. Interferon-gamma release assays (IGRAs) overcome some limitations of the tuberculin skin test, but implementation of IGRA testing in low-resource settings is challenging. METHODS: In this feasibility study, we evaluated performance of a novel digital lateral-flow assay, the QIAreach® QuantiFERON® TB (QIAreach-QFT) test, against the QuantiFERON®-TB Gold Plus (QFT-Plus) assay. A population with a mix of risk factors for TB infection (111 donors) were sampled over multiple days. A total of 207 individual blood samples were tested according to the manufacturer’s instructions. RESULTS: The overall percentage agreement was 95.6% (two-sided 95% CI 91.8–98), with a positive percentage agreement (i.e., sensitivity) of 100% (95% CI 94.7–100) and a negative percentage agreement (i.e., specificity) of 95.6% (95% CI 90.6–98.4). All QFT-Plus positive specimens with TB1-Nil and TB2-Nil values less than 1 IU/ml tested positive on QIAreach-QFT. CONCLUSIONS: QIAreach QFT is a deployable, accurate testing solution for decentralised testing. It has the potential to overcome key hurdles for TB infection screening in high-burden settings thus helping to achieve the WHO End TB programme goals.
