Deep cervical lymph nodes in Parkinson's disease and atypical Parkinson's disease: A potential ultrasound biomarker for differential diagnosis.

Background: Parkinson's disease (PD) is a common degenerative disease caused by abnormal accumulation of α-synuclein. The glymphatic pathway is essential for removing macromolecular proteins including α-synuclein from the brain, which flows into deep cervical lymph nodes (DCLNs) through meningeal lymphatics. As a terminal station for the cerebral lymphatic system drainage, DCLNs can be easily assessed clinically. Objectives: Although the drainage function of the cerebral lymphatic system is impaired in PD, the correlation between DCLNs and PD remains unknown. Design: Single-center retrospective cross-sectional study. Methods: The size of the DCLNs were measured using ultrasound. The Movement Disorder Society Sponsored Revision Unified Parkinson's Disease Rating Scale and other scales were used to assess PD motor and non-motor symptoms. Results: Compared with the healthy control (HC) and the atypical Parkinson's disease (AP) groups, the size of the second and third DCLNs in the Parkinson's disease (PD) group was significantly smaller (P < .05). The width diameter of the third DCLN (DCLN3(y)) was significantly smaller in the PD group than in the AP group (P = .014). DCLN3(y) combined with a variety of clinical features improved the sensitivity of AP identification (sensitivity = .813). Conclusion: DCLNs were able to distinguish HC, PD and AP and were mainly located in Robbins ΙΙA level. PD and AP were associated with different factors that influenced the size of the DCLNs. DCLN3(y) plays an important role in differentiating PD from AP, which, combined with other clinical features, has the ability to distinguish PD from AP; in particular, the sensitivity of AP diagnosis was improved.

DCLN has potential diagnostic value in differentiating PD from AP.

Generation of Anti-Mastitis Gene-Edited Dairy Goats with Enhancing Lysozyme Expression by Inflammatory Regulatory Sequence using ISDra2-TnpB System.

Gene-editing technology has become a transformative tool for the precise manipulation of biological genomes and holds great significance in the field of animal disease-resistant breeding. Mastitis, a prevalent disease in animal husbandry, imposes a substantial economic burden on the global dairy industry. In this study, a regulatory sequence gene editing breeding strategy for the successful creation of a gene-edited dairy (GED) goats with enhanced mastitis resistance using the ISDra2-TnpB system and dairy goats as the model animal is proposed. This included the targeted integration of an innate inflammatory regulatory sequence (IRS) into the promoter region of the lysozyme (LYZ) gene. Upon Escherichia Coli (E. coli) mammary gland infection, GED goats exhibited increased LYZ expression, showing robust anti-mastitis capabilities, mitigating PANoptosis activation, and alleviating blood-milk-barrier (BMB) damage. Notably, LYZ is highly expressed only in E. coli infection. This study marks the advent of anti-mastitis gene-edited animals with exogenous-free gene expression and demonstrates the feasibility of the gene-editing strategy proposed in this study. In addition, it provides a novel gene-editing blueprint for developing disease-resistant strains, focusing on disease specificity and biosafety while providing a research basis for the widespread application of the ISDra2-TnpB system.

Metformin ameliorates neuroinflammatory environment for neurons and astrocytes during in vitro and in vivo stroke and tobacco smoke chemical exposure: Role of Nrf2 activation.

Despite the protective nature of the blood-brain barrier (BBB) and brain-protecting tissues, some types of CNS injury or stress can cause cerebral cytokine production and profound alterations in brain function. Neuroinflammation, which can also be accompanied by increased cerebral cytokine production, has a remarkable impact on the pathogenesis of many neurological illnesses, including loss of BBB integrity and ischemic stroke, yet effective treatment choices for these diseases are currently lacking. Although little is known about the brain effects of Metformin (MF), a commonly prescribed first-line antidiabetic drug, prior research suggested that it may be useful in preventing BBB deterioration and the increased risk of stroke caused by tobacco smoking (TS). Therefore, reducing neuroinflammation by escalating anti-inflammatory cytokine production and declining pro-inflammatory cytokine production could prove an effective therapeutic strategy for ischemic stroke. Hence, the current investigation was planned to explore the potential role of MF against stroke and TS-induced neuroinflammation and reactive oxygen species (ROS) production. Our studies revealed that MF suppressed releasing pro-inflammatory mediators like tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) by aiming at the nuclear factor kappa B (NF-κB) signaling pathway in primary neurons and astrocytes. MF also upregulated anti-inflammatory mediators, like interleukin-10 (IL-10), and interleukin-4 (IL-4), by upregulating the Nrf2-ARE signaling pathway. Adolescent mice receiving MF along with TS exposure also showed a notable decrease in NF-κB expression compared to the mice not treated with MF and significantly decreased the level of TNF-α, IL-1ß, MCP-1, and MIP-2 and increased the levels of IL-10 and IL-4 through the activation of Nrf2-ARE signaling pathway. These results suggest that MF has anti-neuroinflammatory effects via inhibiting NF-κB signaling by activating Nrf2-ARE. These studies support that MF could be a strong candidate drug for treating and or preventing TS-induced neuroinflammation and ischemic stroke.

Luteolin-7-diglucuronide, a novel PTP1B inhibitor, ameliorates hepatic stellate cell activation and liver fibrosis in mice.

Liver fibrosis, one of the leading causes of morbidity and mortality worldwide, lacks effective therapy. The activation of hepatic stellate cells (HSCs) is the dominant event in hepatic fibrogenesis. Luteolin-7-diglucuronide (L7DG) is the major flavonoid extracted from Perilla frutescens and Verbena officinalis. Their beneficial effects in the treatment of liver diseases were well documented. In this study we investigated the anti-fibrotic activities of L7DG and the potential mechanisms. We established TGF-ß1-activated mouse primary hepatic stellate cells (pHSCs) and human HSC line LX-2 as in vitro liver fibrosis models. Co-treatment with L7DG (5, 20, 50 µM) dose-dependently decreased TGF-ß1-induced expression of fibrotic markers collagen 1, α-SMA and fibronectin. In liver fibrosis mouse models induced by CCl4 challenge alone or in combination with HFHC diet, administration of L7DG (40, 150 mg·kg-1·d-1, i.g., for 4 or 8 weeks) dose-dependently attenuated hepatic histopathological injury and collagen accumulation, decreased expression of fibrogenic genes. By conducting target prediction, molecular docking and enzyme activity detection, we identified L7DG as a potent inhibitor of protein tyrosine phosphatase 1B (PTP1B) with an IC50 value of 2.10 µM. Further studies revealed that L7DG inhibited PTP1B activity, up-regulated AMPK phosphorylation and subsequently inhibited HSC activation. This study demonstrates that the phytochemical L7DG may be a potential therapeutic candidate for the treatment of liver fibrosis.

N-acyl homoserine lactone cell-cell diffusible signalling in the Ralstonia solanacearum species complex.

Ralstonia solanacearum species complex (RSSC) includes soilborne bacterial plant pathogens with worldwide distribution and wide host ranges. Virulence factors are regulated via four hierarchically organized cell-cell contact independent quorum-sensing (QS) signalling systems: the Phc, which uses as signals (R)-methyl 3-hydroxypalmitate [(R)-3-OH PAME] or (R)-methyl 3-hydroxymyristate [(R)-3-OH MAME], the N-acyl homoserine lactone (AHL)-dependent RasI/R and SolI/R systems, and the recently identified anthranilic acid-dependent system. The unique Phc QS system has been extensively studied; however, the role of the two AHL QS systems has only recently been addressed. In this microreview, we present and discuss current data of the SolI/R and RasI/R QS systems in the RSSC. We also present the distribution and frequency of these AHL QS systems in the RSSC, discuss possible ecological roles and evolutive implications. The complex QS hierarchical networks emphasizes the crucial role of cell-cell signalling in the virulence of the RSSC.

Deleting an xylosidase-encoding gene VdxyL3 increases growth and pathogenicity of Verticillium dahlia.

Introduction: Verticillium dahliae causes a devastating Verticillium wilt disease on hundreds of plant species worldwide, including cotton. Understanding the interaction mechanism between V. dahliae and its hosts is the prerequisite for developing effective strategies for disease prevention. Methods: Here, based on the previous observation of an xylosidase-encoding gene (VdxyL3) in V. dahliae being obviously up-regulated after sensing root exudates from a cotton variety susceptible to this pathogen, we investigated the function of VdxyL3 in the growth and pathogenesis of V. dahliae by generating its deletion-mutant strains (ΔVdxyL3). Results: Deleting VdxyL3 led to increased colony expansion rate, conidial production, mycelial growth, carbon and nitrogen utilization capacities, and enhanced stress tolerance and pathogenicity of V. dahliae. VdxyL3 is a secretory protein; however, VdxyL3 failed to induce cell death in N. benthamiana based on transient expression experiment. Transcriptomic analysis identified 1300 genes differentially expressed (DEGs) between wild-type (Vd952) and ΔVdxyL3 during infection, including 348 DEGs encoding secretory proteins, among which contained 122 classical secreted proteins and 226 non-classical secreted proteins. It was notable that of the 122 classical secretory proteins, 50 were carbohydrate-active enzymes (CAZymes) and 58 were small cysteine rich proteins (SCRPs), which were required for the pathogenicity of V. dahliae. Conclusion: The RNA-seq data thus potentially connected the genes encoding these proteins to the pathogenesis of V. dahliae. This study provides an experimental basis for further studies on the interaction between V. dahliae and cotton and the pathogenic mechanism of the fungus.

Life history parameters of Ectropis grisescens (Lepidoptera: Geometridae) in different Wolbachia infection states.

Wolbachia, a prevalent intracellular symbiotic bacterium in insects, plays a significant role in insect biology. Ectropis grisescens (Warren; Lepidoptera: Geometridae) is a devastating chewing pest distributed in tea plantations throughout China. However, it is unclear how Wolbachia titers affect the fitness and reproduction of E. grisescens. In this study, the impacts of 3 different infection lines, naturally Wolbachia-infected, Wolbachia-uninfected, and Wolbachia transinfected, regarding the life history traits of E. grisescens, were evaluated using the age-stage, 2-sex life table. Wolbachia infection significantly shortened preadult duration and preoviposition periods and notably increased the fecundity, net reproductive rate, and finite rate of increase. Meanwhile, population projection indicated that E. grisescens population size with Wolbachia infection can increase faster than without. These results indicate that Wolbachia plays a regulatory role in the fitness of E. grisescens. It is also noted that the life history parameters of E. grisescens may positively correlate with Wolbachia titers. These findings could aid in pest management in tea gardens.

Designing a sparse sensor array for sound field reconstruction using compressive-equivalent source method.

The compressive-equivalent source method (C-ESM) can reconstruct the sound field radiated by sparsely distributed sound sources with a reduced number of sensors. To ensure the performance of the C-ESM, the transfer matrix between the sensors and equivalent point sources should exhibit sufficient incoherence. Given that the configuration of the sensor array affects this incoherence condition, concern regarding the sensor array design would arise. To address such concern, this paper proposes a sensor array design approach. The primary objective of this approach is to minimize the mean coherence of the transfer matrix within the developed iterative framework, providing the incoherence condition required by the C-ESM. Subsequently, the designed sensor array is utilized by the C-ESM for the reconstructions. The effectiveness and practicality of the proposed approach are validated through numerical simulations and experiments.

Prevalence and related factors for neck pain in military personnel: a systematic review.

Purpose: In the military, neck pain is second to low back pain among musculoskeletal disorders. However, the prevalence and related factors of neck pain in military personnel have not been systematically investigated, which may lead to the lack of neck pain prevention and the generation of additional medical expenses, posing challenges to medical care. This review aimed to obtain the prevalence and related factors for neck pain in military personnel in an attempt to provide directions for prevention and intervention. Methods: We searched PubMed, Embase, and Cochrane databases in December 2021. Two researchers independently screened studies according to eligibility criteria and assessed study quality. Results: We screened titles and abstracts of 503 articles, and 17 articles met the inclusion criteria. Sixteen articles received moderate to high-quality evaluations. Neck pain is common in the military, with 1-year prevalence as high as 83% and lifetime prevalence as high as 78%. Old age (OR = 5.0), poor neck mobility (OR = 3.61), shoulder pain (OR = 4.9), low back pain (OR = 2.3), high-G pilots (OR = 1.6), longer flight time (OR = 2.53), type of aircraft (OR = 3.93), and use of helmets and night vision systems (OR = 1.9) may be associated with the prevalence of neck pain. Conclusion: Neck pain is highly prevalent in military personnel and exhibits a substantial lifetime prevalence rate. The high prevalence rate of neck pain in the military is related to many individual-related factors and work-related factors. The in-depth assessment and prevention of specific factors is an important direction of future research.

Reduced Platelets Associated with All-Cause Mortality in the Pediatric Intensive Care Unit.

Platelets are crucial for maintaining physiological equilibrium, thrombosis formation, inflammation, bacterial defense, wound repair, angiogenesis, and tumorigenesis. In the Pediatric Intensive Care Unit (PICU), children frequently exhibit platelet reductions or functional alterations due to diverse pathological conditions, which significantly influence disease progression and therapeutic approaches. We analyzed the association between platelets count and its derived parameters and all-cause mortality. Adjusted smoothing spline plots, subgroup analysis and segmented multivariate logistic regression analysis were conducted to estimate the relative risk between proportional risk between platelets and all-cause mortality. Of the 11625 children, 677 (5.82%) died. After adjusting for confounders, there was a negative association between platelets and the risk of all-cause mortality in PICU. For every 100 × 10^9/L increase in platelets, the risk of death was reduced by 17% (adjusted OR = 0.83, 95% CI: 0.78, 0.89). The results of sensitivity analysis showed that in different stratified analyses (age, ICU category,WBC Count), the effect of platelets count on all-cause mortality remained stable. After adjusting for inflammation, nutrition, and liver function factors, platelets reduction is still an independent risk factor for PICU all-cause mortality.

Advancing PAM-less genome editing in soybean using CRISPR-SpRY.

Although CRISPR-Cas9 technology has been rapidly applied in soybean genetic improvement, it is difficult to achieve the targeted editing of the specific loci in the soybean complex genome due to the limitations of the classical protospacer adjacent motif (PAM). Here, we developed a PAM-less genome editing system mediated by SpRY in soybean. By performing targeted editing of representative agronomic trait targets in soybean and evaluating the results, we demonstrate that the SpRY protein can achieve efficient targeted mutagenesis at relaxed PAM sites in soybean. Furthermore, the SpRY-based cytosine base editor SpRY-hA3A and the adenine base editor SpRY-ABE8e both can accurately induce C-to-T and A-to-G conversion in soybean, respectively. Thus, our data illustrate that the SpRY toolbox can edit the soybean genomic sequence in a PAM-free manner, breaking restrictive PAM barriers in the soybean genome editing technology system. More importantly, our research enriches soybean genome editing tools, which has important practical application value for precise editing and molecular design in soybean breeding.

Complete mitochondrial genome of the edible mushroom Singerocybe alboinfundibuliformis (Clitocybaceae, Agaricales).

Singerocybe alboinfundibuliformis (Seok et al.) Yang, Qin & Takah 2014 is an edible mushroom distributed in several East or Southeast Asian countries. Herein, we report the mitochondrial genome of S. alboinfundibuliformis based on Illumina sequencing data. The overall length of the mitochondrial genome is 64,279 bp, with a GC content of 29.0%. It contains 14 typical protein-coding genes, 27 tRNA genes, two rRNA genes, and 13 intergenic ORFs. Most of these genes (39 out of 56) are transcribed at the forward strand, and few (17 out of 56) are transcribed at the reverse strand. Among these genes, only the rnl gene is invaded by an intron, and all other genes are intron-free. Phylogenetic analysis based on mitochondrial amino acid sequences supports the phylogenetic position of S. alboinfundibuliformis in Clitocybaceae, being close to Lepista sordida (Schumach.) Singer 1951. This study serves as a springboard for future investigation on fungal evolution in Clitocybaceae.

Complete mitochondrial genome of the bird's nest fungus Nidula shingbaensis (Nidulariaceae, Agaricales).

Bird's nest fungi involve six different genera, but only one of these genera (i.e. Cyathus) have available mitochondrial genomes (mitogenomes) to date. In this study, we report the first mitogenome in the genus Nidula with Nidula shingbaensis K. Das & R.L. Zhao 2013 as a representative. The mitogenome is a circular molecule of 65,793 bp with a GC content of 26.2%. There are a total of 43 genes, including 14 typical protein-coding genes, 26 tRNA genes, two rRNA genes, and one free-standing intergenic open reading frame (ORF). Three introns (two in cox1 and one in cob) are present in the mitogenome, with each containing an ORF encoding for a LAGLIDADG endonuclease. Phylogenetic analysis based on mitochondrial amino acid sequences confirms the phylogenetic placement of N. shingbaensis in Nidulariaceae in Agaricales. This study serves as a springboard for future investigation on fungal evolution in Nidulariaceae.

Research on evaluation indicators of healthspan for veterans: A single-center exploratory study.

Objective: To explore a definition of healthspan that based on actual situation of veterans is of significance for improving their health status and life quality. Methods: This was a retrospective study. Based on the medical data of veterans from the Chinese PLA General Hospital. Total of 1,421 subjects were enrolled to this study, among which 441 deceased cases were further analyzed. The indicators of healthspan of the subjects was calculated from four dimensions (the status of chronic diseases, physical function, social function and psychological function). The risk factors for death were analyzed in a population cohort from 2008 to 2021 (including 763 subjects, among which 372 were deceased). Results: The average lifespan and adjusted healthspan of the subjects were 93.3 years and 75.1 years, respectively. The four dimensions of healthspan were: adjusted healthspan without chronic diseases was 76.3 years, social function-related healthspan was 88.8 years, physical function-related healthspan was 91.5 years, and psychological function-related healthspan was 92.7 years. By analyzing the cohort in 2008, it was inferred that the main risk factors for the death of veterans were poor nutritional status, renal function injury, high blood pressure, high blood sugar, and aging. Conclusions: This study proposed four dimensions related to "healthspan" for Chinese veterans (adjusted healthspan without chronic diseases, physical function-related healthspan, social function-related healthspan, and psychological function-related healthspan). Besides, poor nutritional status, renal function injury, and high blood pressure were the most important risk factors affecting the death of veterans.

CircCDR1as orchestrates the advancement of asthma triggered by PM2.5 through the modulation of ferroptosis.

Exposure to fine particulate matter (PM2.5) in the ambient environment augments susceptibility to respiratory ailments. Circular RNAs, a distinctive subclass of endogenous non-coding RNAs, have been acknowledged as pivotal regulators of pathological conditions. Ferroptosis, an innovative iron-dependent form of cellular demise, has emerged as a consequential participant in numerous maladies. Despite the established association between PM2.5 exposure and the exacerbation of asthma, scant investigations have probed into the implication of circRNAs and ferroptosis in PM2.5-induced asthma. Consequently, this inquiry sought to scrutinize the potential involvement of circCDR1as and ferroptosis in PM2.5-induced asthma. Through the formulation of a PM2.5 exposure model in asthmatic mice and an in vitro cellular model, it was discerned that PM2.5 induced ferroptosis, thereby intensifying asthma progression. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) revealed an upregulation of circCDR1as in the PM2.5-stimulated asthma cell model. Molecular biology assays demonstrated that diminished circCDR1as expression hindered the onset of ferroptosis in response to PM2.5 exposure. Notably, Ferrostatin-1 (Fer-1), an inhibitor of ferroptosis, manifested the ability to impede the advancement of asthma. Mechanistically, RNA pull-down and molecular biology experiments substantiated that circCDR1as selectively bound to insulin-like growth factor 2 mRNA binding protein 2 (IGF2BP2), thereby modulating the occurrence of ferroptosis. CircCDR1as emerged as a potential orchestrator of asthma progression by regulating ferroptosis under PM2.5 exposure. Additionally, PM2.5 exposure elicited activation of the Wnt/ß-catenin signaling pathway, subsequently influencing the expression of C-myc and Cyclin D1, ultimately exacerbating asthma development. In summation, the interaction between circCDR1as and IGF2BP2 in regulating ferroptosis was identified as a critical facet in the progression of asthma under PM2.5 exposure. This investigation underscores the pivotal roles of circCDR1as and ferroptosis in PM2.5-induced asthma, offering a novel theoretical foundation for the therapeutic and preventive approaches to asthma.

Analytical method for studying acoustic fields radiated by general spherical sound sources in thermoviscous fluids.

The study of acoustic radiation from spherical sound sources plays a crucial role in understanding the thermoviscous effects in practical acoustic problems. However, finding a general solution of acoustic radiation from spherical sound sources in thermoviscous fluids remains a formidable challenge. To advance this issue, an analytical method is developed in this paper to calculate the acoustic field radiated by spherical sound sources with the isothermal boundary condition and arbitrary velocity boundary condition. The developed method is utilized to present the solutions of the acoustic field generated by an oscillating sphere and a general spherical sound source, and the accuracy and validity of these solutions are verified through analytical and numerical methods.

PET/CT Recognition of Costal Cartilage Infection After Breast Implant Surgery.

BACKGROUND: Postoperative infection of breast implants can lead to implant removal and other complications. This study aimed to investigate the presence of costal cartilage infection following breast implant surgery and the diagnostic role of PET/CT in identifying this rare complication. PATIENTS AND METHODS: A retrospective study included 16 patients with persistent infections after breast implant removal surgery. Patients underwent PET/CT scans before surgery, and surgical plans were made based on PET/CT findings. Surgical procedures were guided by PET/CT, and specimens were collected for pathological examination and microbiological culture. Follow-up assessments were performed at 1, 3, and 12 months postoperatively. RESULTS: Among the 16 patients, 11 were diagnosed with costal cartilage infection, whereas 5 had subcutaneous soft tissue infections. PET/CT accurately identified costal cartilage infection in all cases and localized the infected costal cartilage in the majority of cases. Microbiological culture results showed various pathogens. All patients were cured with one or staged surgery. CONCLUSION: Costal cartilage infection following breast implant surgery is a significant concern. PET/CT plays a crucial role in the accurate diagnosis and localization of infected costal cartilage, aiding in appropriate surgical management. Patients should be closely monitored for the possibility of costal cartilage infection when experiencing persistent symptoms after breast implant surgery.

Rosacea Epidemiological Investigation and Etiology Exploration in the Plateau Area.

BACKGROUND: The epidemiology of 2 neighboring cities of differing altitude in Northwest China is unknown. The present study investigated the prevalence of rosacea in a high-altitude city and a low-altitude city. METHODS: The prevalence study was conducted via clinical examination of male and female participants in the following age groups: 5-17, 18-30, 31-50, and 51-70 years. Rosacea subtype was also determined as erythematotelangiectatic rosacea (ETTR) or papulopustular rosacea (PPR). RESULTS: The rosacea prevalence (RP) in the low-altitude city was 33.8% ± 1.2% (95% CI, ETTR = 1794, PPR = 174, n = 5794). RP in the high-altitude city has a notably higher reading of 47.7% ± 1.4% (95% CI, ETTR = 2090, PPR = 219, n = 4796). In both cities, the ETTR subtype predominated, and there was marked increase in RP among females. RP in low-altitude city females was steady across all age groups, while RP in low-altitude city males showed a declining trend with age. RP in high-altitude city females indicated a slightly increasing trend with age, while RP in males again showed a declining trend with age. Based on the results of this high-altitude city and low-altitude city study, there are an estimated 2.1 million people with rosacea, from 2 cities with a total population of 5.4 million. CONCLUSIONS: Due to the high altitude and accompanying increased UV radiation, cold climate, and reduced oxygen density, the greater northwest region of China is expected to experience high RP rates.

An alignment algorithm using coherent twin boundaries as internal reference in 3D-EBSD.

A three-dimensional (3D) microstructural volume is reconstructed from a stack of two-dimensional sections which was obtained by serial sectioning coupled with electron back scattering diffraction (EBSD) mapping of a 316L austenitic stainless steel. A new alignment algorithm named linear translation by minimising the indicator (LTMI) is proposed to reduce the translational misalignments between adjacent sections by referencing to coherent twin boundaries which are flat and lying on {111} planes. The angular difference between the measured orientation of a flat twin boundary and that of the {111} plane is used as an indicator of the accuracy of the alignment operations. This indicator is minimised through linear translations of the centroids of triangular facets, which constitute grain boundaries at a distance not restricted by the in-plane step size of the EBSD maps. And hence the systematic trend in the translational misalignments can be effectively reduced. The LTMI alignment procedure proposed herein effectively corrects the misalignments remained by other methods on a 3D-EBSD data prepared using serial sectioning methods. The accuracy in distinguishing between coherent and incoherent twin boundaries is significantly improved.

Association Between the Inflammatory Potential of Diet and Constipation Among Adults in the United States: A Cross-sectional Study.

OBJECTIVE: To investigate the potential association between Dietary Inflammatory Index (DII) scores and constipation among a sample of adults in the United States. METHODS: This cross-sectional study used data from adult participants in the 2005 to 2010 National Health and Nutrition Examination Survey (ie, "NHANES"). Self-reported information was used to identify cases of constipation. The DII was used to assess inflammatory potential of the diet. Odds ratios (ORs) and corresponding 95% CIs for the association between the DII and constipation were determined using multivariate logistic regression modeling. Stratified analyses explored whether there was effect modification to influence the relationship between DII and constipation. RESULTS: Of 8272 subjects, 759 reported constipation, and 7513 did not, corresponding to a prevalence of 9.2%. After adjusting for age, gender, race/ethnicity, marital status, education level, smoking status, alcohol consumption, physical activity, body mass index (BMI), cardiovascular diseases (CVD), hypertension, stroke, diabetes, energy intake, carbohydrate intake, and selective serotonin reuptake inhibitor (SSRI) use. Compared with lower DII scores group T1 (-5.28 to ≤0.72), the adjusted OR values for DII scores and constipation in T2 (>0.72 to ≤2.50) and T3 (>2.50 to 5.24) were 1.27 (95% CI: 1.02-1.58, P=0.029) and 1.43(95% CI: 1.14-1.8, P=0.002). Subgroup analyses showed that there were effect modification of gender and physical activity factors on DII scores and constipation. CONCLUSIONS: Results of this cross-sectional study suggest that a higher dietary inflammatory index score was associated with increased risk of constipation after adjustment for confounding in a multivariable analysis. gender and physical activity were found to be an effect modifier of this relationship.
