Cell-free supernatants from plant growth-promoting rhizobacteria Bacillus albus strains control Aspergillus flavus disease in peanut and maize seedlings

BackgroundAspergillus flavus, a seed-borne fungal pathogen, colonizes host plants and exploits nutrients, hindering the growth of seedlings such as peanut and maize. This study investigates the effectiveness of cell-free supernatants (CFSs) from the plant growth-promoting rhizobacteria (PGPR) Bacillus albus strains NNK24 and NDP61, which belong to the Bacillus cereus group, in suppressing A. flavus AF1.ResultsThe antifungal activity of these CFSs was attributed to their surfactant properties and chemical composition. These were characterized using rapid chemical assays and ultra-high-performance liquid chromatography-electrospray ionization-quadrupole time-of-flight/mass spectrometry (UHPLC-ESI-QTOF/MS), combined with bioinformatic tools such as Global Natural Product Social Molecular Networking (GNPS) and Natural Products Atlas (NPAtlas). Identified putative antifungal compounds included two diketopiperazines (cyclo(Pro-Leu) and cyclo(2-hydroxy-Pro-Leu)), four macrolactins (7-O-succinyl macrolactin A, 7-O-methyl-5′-hydroxy-3′-heptenoate-macrolactin, macrolactin B, and macrolactin C), two siderophores (petrobactin and bacillibactin), and three cyclic lipopeptides (kurstakin 1, 2 or 3, and 4). These compounds are hypothesized to act synergistically via multiple mechanisms, including disruption of fungal membranes, iron capture, direct antibiosis, and triggering plant immunity. Both CFSs strongly suppressed the harmful effects of A. flavus AF1 and seed-borne A. flavus on peanut and maize seedlings, reducing disease incidence (DI) and disease severity index (DSI) compared to controls. The disease control efficacy (DCE) of the CFSs was comparable to that of the commercial fungicide. Additionally, the CFSs enhanced seed germination, vigor, seedling length, and weight in both peanut and maize. Vigor index (VI) values increased by 222.4–286.0% in peanuts and 181.7–216.4% in maize at 7 days after treatment (DAT).ConclusionCFSs of B. albus NNK24 and NDP61 show significant potential as bioprotective agents for sustainable agriculture. Importantly, their use eliminates the need for live bacterial cells from the B. cereus group, addressing biosafety concerns.Graphical abstract

Comparative cardiovascular safety of romosozumab versus bisphosphonates in Japanese patients with osteoporosis: a new-user, active comparator design with instrumental variable analyses.

This study analyzed the association of romosozumab, a human monoclonal antibody with bone-forming and bone resorption-inhibiting effects, and bisphosphonates with the development of cardiovascular disease among patients with osteoporosis. A new-user design was employed to address selection bias, and instrumental variable analysis was used to address confounding by indication. Japanese patients aged ≥40years, diagnosed with osteoporosis or experienced a fragility fracture, were admitted to medical facilities covered by a commercial administrative claims database, and newly prescribed romosozumab or bisphosphonates after the commercialization of romosozumab in Japan (March 4, 2019) were included based on verification of a 180-day washout period. Cardiovascular disease (myocardial infarction or stroke) was identified based on information regarding diagnosis, medical procedures, and drug codes. Facility-level prescription preference for romosozumab was used as an instrumental variable, defined as the proportion of romosozumab prescribed at the patient's facility within 90days prior to the index date. Of the 59 694 included prescriptions, 8808 were for romosozumab and 50 886 were for bisphosphonates. The mean age in the romosozumab group was higher than that in the bisphosphonates group (80.5 vs. 78.2years, respectively), and most patients were females (85.3 vs. 80.2%, respectively). The incidence of cardiovascular disease within 1year of prescription was 12.3 per 100 person-years for romosozumab versus 11.4 for bisphosphonates (unadjusted incidence rate ratio: 1.08, 95% confidence interval: 1.00-1.18). An instrumental variable analysis using the two-stage residual inclusion method yielded a hazard ratio of 1.30 (95% confidence interval: 0.88-1.90) for romosozumab compared with bisphosphonates over 1year. Although possibly underpowered, this study showed that no definitive evidence of increased cardiovascular risk associated with romosozumab use compared with bisphosphonates was observed in patients with osteoporosis. These findings should be further validated by larger pharmacoepidemiological studies to alleviate clinicians' concerns about romosozumab's safety.

High Serum S100B Protein Levels as a Risk Factor for Impaired Cognitive Function in Acute Non- Hemorrhagic Stroke: A Literature Review

The incidence of acute non-hemorrhagic stroke disease has a high disability rate and mortality rate and is a serious threat to people’s health and life and can burden families and society. The development of stroke after the onset of acute stroke, especially acute non-hemorrhagic stroke is not uncommon and has become a popular research topic in recent years. Various mechanism can occur, one of which is neuroinflammation. Stroke often leads to lifelong disability, including motor impairment, cognitive impairment, language impairment, and psychological impairment. Serum S100B is a calcium-binding protein that can determine disease severity and predict clinical outcomes to monitor disease progression and response to treatment. It was reported that serum S100B protein levels were detected to be higher in patients with cognitive impairment compared to normal ones. Keywords: Serum S100B protein, cognitive impairment, non-hemorrhagic stroke

Periodontitis and the incidence of inflammatory bowel diseases: A nationwide population-based cohort study.

Periodontitis and other oral health indicators are reportedly related to systemic inflammation. Our study aimed to investigate a possible association of oral health status (periodontitis and number of missing teeth) and oral hygiene behaviors (frequency of tooth brushing, dental visit, and dental scaling) with the risk of inflammatory bowel disease (IBD) incidence. Utilizing the Korean National Health Insurance Database, we conducted a nationwide, population-based cohort study involving participants from the 2003 national health screening program. We followed these individuals until December 2020 or the occurrence of censoring events. Crohn's disease (CD) and ulcerative colitis (UC) were defined by disease classification codes from the International Classification of Diseases-10 and national codes for rare intractable disease. The occurrence of IBD was analyzed using the Cox proportional hazard model, with propensity score matching (PSM) performed to balance baseline characteristics between participants with and without periodontitis. Our analysis involved a total of 2,272,012 participants with a median follow-up period of 17.0 years. The incidence rates for CD and UC were 11.6 and 32.4 per 100,000 person-years, respectively. In multivariable analysis after PSM, the presence of periodontitis was associated with an increased risk of both CD (adjusted hazard ratio [aHR], 1.32, 95% confidence interval [CI], 1.14-1.52, p<0.001) and UC (aHR 1.21, 95% CI 1.10-1.32, p<0.001). Conversely, frequent tooth brushing ≥3 times a day was associated with a reduced risk of CD (aHR 0.81, 95% CI 0.65-0.99, p=0.049) but no significant association was observed with UC. Periodontitis may augment the risk of incidence for CD and UC. This association underscores the potential significance of periodontal health in the context of IBD, emphasizing the importance of comprehensive oral hygiene practices and potential preventive strategies to reduce the risk of CD and UC incidence.

Combined application of methyl jasmonate and Bacillus subtilis LLCG89 suppresses blue and green mold of lemon (Citrus limon L.).

Bacillus species produce antimicrobial lipopeptides (LPs) and methyl jasmonate (MeJA) induces resistance in harvested fruits against postharvest pathogens. However, there is limited evidence of the combined efficacy of Bacillus LPs and MeJA to suppress postharvest diseases. This study presents the combined effect of Bacillus LPs and MeJA to suppress P. digitatum and P. italicum associated with green and blue mold of lemon. Eight Bacillus strains were screened in a direct antagonism plate assay, where Bacillus subtilis LLCG89 and B. atrophaeus HFZ23 exhibited the highest inhibition of both molds. Subsequently, in an in vitro assay, LPs extracted from LLCG89 demonstrated the highest antifungal activity against both pathogens compared to HFZ23. When combined with MeJA, LLCG89 LPs reduced the lesion diameter and disease incidence of blue and green mold on lemon fruit. Co-application of MeJA and LLCG89 LPs decreased the levels of MDA, H2O2, and electrolyte leakage compared to single treatments and controls. Furthermore, treatment with MeJA and LLCG89 LPs increased the activities of defense enzymes including SOD, CAT, POD, PPO, CHI, GLU, APX, and PAL with peak activity between 48 to 72 h. The co-application of MeJA and LLCG89 LPs showed the highest enzyme activity compared to the control. Postharvest quality analysis indicated that co-application of LLCG89 LPs and MeJA showed little impact on fruit quality. The findings of our study highlight the potential of Bacillus-derived LPs and MeJA as effective tools for managing the Penicillium decay of lemons by maintaining fruit quality. © 2025 Society of Chemical Industry.

Global burden of bacterial skin diseases from 1990 to 2045: an analysis based on global burden disease data.

Bacterial skin diseases are a category of inflammatory skin conditions caused by bacterial infections, which impose a significant global disease burden. However, they have not been well assessed or predicted on a global scale. It is necessary to update the estimates and forecast future trends of the global burden of bacterial skin diseases to evaluate the impact of past healthcare policies and to provide guidance and information for new national and international healthcare strategies. We aimed to describe the burden and trend of bacterial skin diseases and to predict the burden up to 2045. To achieve this, we employed a cross-sectional analysis based on Global Burden of Disease (GBD) data, utilizing advanced statistical models to quantify trends and forecast future burdens. Data on incidence and disability-adjusted life years (DALYs) of bacterial skin diseases were obtained from Global Burden of Disease 2021. We used average annual percent change (AAPC) by Joinpoint Regression to quantify the temporal trends. We conducted decomposition analysis to understand the contribution of aging, epidemiological changes, and population growth. Bayesian Age-Period-Cohort model was used to predict burden up to 2045. Global incidence rate of bacterial skin diseases increased from 8,988.74 per 100,000 in 1990 to 10,823.88 per 100,000, with AAPC of 0.62% (0.61 ~ 0.63%). The highest incidence rate was in low Socio-demographic Index (SDI) region and population aged < 35. The DALYs rate increased from 20.82 per 100,000 in 1990 to 25.45 per 100,000 in 2021, with AAPC of -0.11% (-0.34 ~ 0.13%). The highest increase of DALYs was in high SDI region and population aged > 85. Among the three evaluated factors of decomposition analysis, the major drivers of incident case rise were population growth, followed by epidemiological changes; the major drivers of DALYs case rise were population growth, followed by aging. The number of incidence cases has increased since 1990, reaching nearly 90million in 2021 and expected to hit 1.2billion in 2045. The incidence rate has also risen. Meanwhile, DALYs showed an upward trend from 1990 to 2005, peaking at 32/100,000, then a downward trend. Our findings align with our initial objectives, demonstrating a significant increase in the global incidence of bacterial skin diseases and highlighting the need for targeted prevention and treatment strategies. The variation in burden across different regions and age groups underscores the importance of tailored public health interventions. Predictive models suggest a continued rise in incidence rates and incident cases through 2045, emphasizing the urgency for action. This study provides a foundation for future research and policy development aimed at reducing the burden of bacterial skin diseases worldwide.

SURVEILLANCE OF PARASITIC DISEASES IN BULGARIA

The incidence and number of cases of several parasitic diseases subject to mandatory reporting and registration under the Ministry of Health (MoH) 2005 Regulation 21 increased after the end of the global pandemic of COVID-19 in 2023. In addition, parasitic infections imported from endemic tropical regions are recorded annually in the country. A significant number of people are screened for parasitic diseases each year. The primary indication for screening is prophylactic, followed by epidemiological and clinical indications. This report aims to analyse the dynamics of parasitic diseases in 2023. Data from the periodic and annual reports of the RHI, medical institutions and NCIPD were used as inputs. In 2023, 647 781 people were tested for parasites, of whom 2.0% were diagnosed with various parasitic infections. Cystic echinococcosis increased from 89 cases in 2022 to 117 cases in 2023. The annual incidence of the disease increased from 1.3% in 2022 to 1.81% in 2023. Regarding soil-transmitted parasitic diseases, 447 people were diagnosed with ascariasis and 50 with trichuriasis. Among the 458 764 people tested, the prevalence of enterobiasis was 1.74%. Out of 1 305 suspected cases, 10 individuals were diagnosed with imported malaria. Unfortunately, the disease was fatal for one patient of Bulgarian nationality. Analysis of the data showed no discernible trend in the incidence of parasitic diseases in 2023. However, cases of cystic echinococcosis show an upward trend. For the first time, no epidemic outbreaks of trichinellosis were recorded in 2023.

First Report of Bacterial Wilt of Ginger Caused by Ralstonia pseudosolanacearum in the Continental United States.

Ginger (Zingiber officinale) is an herbaceous perennial in the Zingiberaceae family grown primarily in tropical to subtropical biomes as a culinary spice, a traditional medicine, and a landscaping plant. While ginger grows at soil temperatures above 20°C, several farmers in the upper Midwestern US farmers grows short-season ginger in high tunnels. In 2023 and 2024, growers in southeastern Minnesota reported a new disease of ginger. USDA traced the origin of the ginger rhizomes imported by these growers to Peru (Soto-Heredia et al., 2024). Plants exhibited wilting, chlorosis, pseudostem collapse, and plant death. Rhizomes were squishy with a fetid, rotting odor. Disease incidence ranged from scattered plants to 50% of the crop. Symptomatic samples tested positive for Ralstonia solanacearum species complex (RSSC) using AgDia ImmunoStrips. Rhizome tissue extracts plated onto CPG + 1% tetrazolium chloride agar and mSMSA agar produced irregular, round-to-fluidal white colonies with pink centers after 48 h of incubation at 28°C (Kelman 1954; Engelbrecht 1994). Diagnostic RSSC phylotype-specific multiplex PCR primers Nmult21:1F, Nmult21:2F, Nmult23:AF, Nmult22:InF, Nmult22:RR, and 759f/760r confirmed isolate identity; two isolates (UMN24-1, UMN24-2) yielded bands at 280 bp and 144 bp, identifying them as RSSC and phylotype I respectively (Fegan and Prior 2005; Opina et al. 1997). Additionally, 16S rRNA PCR of these isolates was sequenced using primers 27F (5'-AGAGTTTGATCMTGGCTCAG-3')/1492R (5'-TACGGYTACCTTGTTACGACTT-3') and shared >99% identity (isolate UMN24-1: 99.00% 27F, 99.53% 1492R; UMN24-2: 99.32% 1492R) with R. pseudosolanacearum (Rps) strain Gj707 (GenBank CP104497.1). Eight ginger plants in individual pots were grown in a Conviron growth chamber (28°C, 250 μmol/m2/s, 16 h photoperiod) and inoculated at the six-leaf stage (6 weeks old) by pipetting 109 CFU of the isolate, UMN24-1, suspended in sterile water into a 30°angled 1 cm incision on the pseudostem. We scored disease incidence based on wilted leaves per total leaves on each plant for 14 days post inoculation (dpi). While control plants remained healthy, inoculated plants showed symptoms (wilting, vascular discoloration, chlorosis) at 4 dpi, were 100% wilted by 6 dpi, and all pseudostems completely collapsed by 11 dpi (Fig. S1). Bacteria recovered from the inoculated plants matched the original isolate in appearance and positively identified as RSSC phylotype I using the PCR analyses described above. To confirm taxonomic identification of UMN24-1, the complete genome of this isolate was sequenced using hybrid Illumina and Oxford Nanopore sequencing (NCBI BioProject ID PRJNA1178296, release date upon publication) (Fig. S2). Average nucleotide identity (ANI) analysis of UMN24-1 using KBase's FastANI app reported 99.8% identity shared with Japanese RSSC phylotype I strain MAFF311693 (GenBank GCF 015698385.1). We also sequenced UMN24-2, and its phylogenetic analysis revealed that the two isolates are clonal (Fig. S2). Hence, we did not submit its sequence to the NCBI. This marks the first documented case of Rps in ginger in the United States. Similar to bacterial wilt in ginger closely related crop like turmeric has been repeatedly reported in northern Europe in recent years (EPPO 2024). While RSSC phylotype I is geographically limited by its minimal cold tolerance, the emergence of a pathogen with a potentially broad host range has worrying implications in a changing climate.

First Report of Phytopythium vexans Causing Root Rot on Tulip Poplar in Tennessee and the United States.

Tulip poplar (Liriodendron tulipifera) is a member of the Magnolia family, is a large, fast-growing, long-lived, deciduous tree native to eastern North America. One-year-old tulip poplar seedlings grown under field conditions in a commercial nursery in Warren County, Tennessee, exhibited severe root rot in May 2024. Dark brown to black lesions were observed on the affected roots. Disease severity was 60% of the affected root area, and disease incidence was 45% of 300 plants. Symptomatic root tissues were surface-disinfected with 70% ethanol and washed twice with distilled water. Small sections of root tissue were placed in Petri dishes containing V8-PARPH (V8 juice agar amended with pimaricin, ampicillin, rifampicin, pentachloronitrobenzene, and hymexazol) agar and incubated at 24°C in an 8-hour photoperiod cycle. After 3 days of incubation, whitish cottony mycelia with radiate and chrysanthemum flower-like growth patterns were observed (Supplementary Fig. 1a). The hyphae were coenocytic and 5.5 μm wide. Sporangia were subglobose with papillate, filamentous to globose smooth oogonia (18.35 to 23.86 μm; n = 50), bell-shaped antheridia, and spherical zoospores that are characteristic of Phytopythium vexans (de Cock et al. 2015) (Supplementary Fig. 1b and c). Total DNA was extracted (DNeasy PowerLyzer Microbial Kit) from 7-day-old isolates FBG7781-1 and FBG7781-2 and amplified using the ITS1/ITS4 (White et al. 1990), NL1/NL4 (Baten et al. 2014), Levup/Fm85mod (Robideau et al. 2011) and Cox2F/Cox2RC4 (Hudspeth et al. 2000) primer pairs. Isolates were sequenced using for genetic markers, including the ribosomal internal transcribed spacer (ITS), the 28S large subunit (LSU) of ribosomal RNA, the mitochondrial cytochrome c oxidase subunit I (COXI) and cytochrome c oxidase subunit II (COXII), respectively. The sequences (GenBank accession nos. PQ555199 and PQ555200 for ITS, PQ555205 and PQ555206 for LSU, PQ562067 and PQ562068 for COXI, and PQ562065 and PQ562066 for COXII) were 100% identical to the ITS, LSU, COX1, and COXII genetic markers of P. vexans isolates in GenBank (ITS: PQ050141, LSU: AB468723, COXI: GU133478, COXII: AB468910). Pathogenicity tests were performed on 1-year-old tulip poplar seedlings grown in 1-gal containers (3.8 L) to fulfill Koch's postulates. Tulip poplar seedlings were drenched and inoculated (150 ml/plant) with a pathogen slurry (two plates of 7-day-old culture/liter) as described in Panth et al. 2021, using isolates FBG7781-1 and FBG7781-2 (five plants per isolate). Five plants were drenched with V8-PARPH agar slurry without the pathogen and served as controls. The study was conducted in a greenhouse maintained at 21 to 23°C and 70% relative humidity and watered twice daily for 2 min using an overhead irrigation system. Fifteen days after inoculation, dark brown lesions developed in the roots of all inoculated plants (Supplementary Fig. 2a). No symptoms were observed in the control plants (Supplementary Fig. 2b). Isolates resembling the morphological characteristics of P. vexans were recovered from inoculated plants using the method described above, and their identity as P. vexans was confirmed by DNA sequencing with the same four primer pairs previously described. Phytopythium vexans has been reported to cause root rot in flowering cherry, ginkgo, red maple, and redbud in Tennessee (Baysal-Gurel et al. 2021, Liyanapathiranage et al. 2023, Panth et al. 2021). To our knowledge, this is the first report of P. vexans causing root rot of tulip poplar in Tennessee, the United States and worldwide. This finding is significantly important for the development of a successful disease management strategy for P. vexans in tulip poplar.

Maternal smoking during infancy increases the risk of allergic diseases in children: a nationwide longitudinal survey in Japan

BackgroundThe incidence of allergic diseases has been increasing in Japan. In particular, a serious decline in the age of onset of allergic rhinitis has been observed. Passive smoking from parental smoking has a significant impact on children’s health; however, it is difficult to restrict smoking in the home. While various studies have previously reported on the relationship between passive smoking and the development of allergic diseases in children. However, there have been no reports on passive smoking and allergic diseases on a national scale.MethodsUsing Japanese national longitudinal survey data (n = 38,444) for newborns born between May 10 and 24, 2010, we assessed parental smoking habits when their children were 6 months old and investigated the association with the development of allergic diseases until the age of 5.5 years. The risk ratios and 95% confidence intervals for the development of different allergic diseases were analyzed after adjusting for potential confounders using Poisson regression with a robust error variance.ResultsThe risk ratio for developing allergic rhinitis/allergic conjunctivitis (AR/AC) in children was significantly higher in the maternal smoking groups ( ≦ 10 cigarettes/day; RR 1.15, 95% CI 1.02–1.30; ≧11 cigarettes/day; RR 1.16, 95% CI 0.93–1.44). Furthermore, associations were found between the maternal smoking group in the presence of paternal smoking and the risk of developing bronchial asthma ( ≦ 10, RR 1.33 95% CI 1.17–1.52; ≧11, RR 1.71 95% CI 1.38–2.1), food allergy ( ≦ 10, RR 1.36 95% CI 1.12–1.63; ≧11, RR 1.25 95% CI 0.84–1.86), atopic dermatitis ( ≦ 10, RR 1.42 95% CI 1.22–1.66; ≧11, RR 1.6 95% CI 1.2–2.13), and AR/AC ( ≦ 10, RR 1.21 95% CI 1.07–1.36; ≧11, RR 1.35 95% CI 1.09–1.67).ConclusionsMaternal smoking during infancy increases the risk of developing AR/AC in children. Considering paternal smoking, maternal smoking further increased the risk of developing allergic diseases in children, suggesting that reducing parental smoking at home may reduce the risk of developing allergic diseases in children.

Development and evaluation of an intervention designed to increase the prioritisation of health by professionals working in the private sector of urban development: study protocol

ABSTRACT The built environment is known to have a significant influence on population and planetary health, including the incidence of non-communicable disease, but evidence suggests that professionals in the land and development industries struggle to prioritise health and health equity when making urban development decisions amidst challenging structures and competing priorities. The aim of this study is to use a mixed-methods approach to develop, deliver, optimise, and evaluate an intervention for professionals working in the private sector of urban development to increase their intention to act on health and health equity where possible. This protocol describes four planned research activities that constitute this intervention’s development, delivery, and evaluation: 1) Intervention development using an iterative co-production process with non-academic industry partners using the Person-Based Approach and following Medical Research Council guidelines on the development of complex interventions; 2) Development of survey questions to assess intervention effectiveness; 3) Delivery and mixed-methods longitudinal evaluation of the intervention; and 4) Evaluation of the impact of co-production and delivery of the intervention with the project’s industry partners.

The effects of type 1 and type 2 diabetes mellitus on bone health in chronic kidney disease.

Fracture is an under-recognized but common complication of diabetes mellitus, with an incidence approaching twofold in type 2 diabetes mellitus (T2DM) and up to sevenfold in type 1 diabetes mellitus (T1DM) compared with that in the general population. Both T1DM and T2DM induce chronic hyperglycaemia, leading to the accumulation of advanced glycosylation end products that affect osteoblast function, increased collagen crosslinking and a senescence phenotype promoting inflammation. Together with an increased incidence of microvascular disease and an increased risk of vitamin D deficiency, these factors reduce bone quality, thereby increasing bone fragility. In T1DM, reduced anabolic stimuli as well as the presence of autoimmune conditions might also contribute to reduced bone mass and increased fragility. Diabetes mellitus is the most common cause of kidney failure, and fracture risk is exacerbated when chronic kidney disease (CKD)-related mineral and bone disorders are superimposed on diabetic changes. Microvascular pathology, cortical thinning and trabecular deterioration are particularly prominent in patients with T1DM and CKD, who suffer more fragility fractures than do other patients with CKD. This Review explores the pathophysiology of bone fragility in patients with diabetes mellitus and CKD and discusses techniques to predict fracture and pharmacotherapy that might reduce fracture risk.

10-year clinical outcomes in Atypical Spitz Tumours: a prospective, single-centre observational cohort study.

Atypical Spitz Tumours are an uncommon group of lesions which demonstrate features of both benign spitz naevi and malignant spitzoid melanoma. Risk stratification of atypical Spitz tumours can be difficult, thus creating uncertainty surrounding their management. We aimed to determine the long-term clinical outcomes of atypical spitz tumours over a 10-year follow-up period, including disease recurrence and incidence of metastasis.

Association of frailty index with incidence of chronic kidney disease: China Health and Retirement Longitudinal Study.

Frailty is an important risk factor for a wide range of chronic diseases and for mortality risk. This study aims to explore the relationship between frailty and incidence of chronic kidney disease (CKD), particularly on the change and accumulation of frailty. Frailty status was assessed using the frailty index (FI, constructed by 31 items) and categorized as robust, pre-frail, and frail. The accumulation and change in frailty were assessed on the basis of frailty status at baseline and a second survey 4years after baseline. Logistic regression was used to estimate the association between frailty and developing CKD. A total of 3597 participants (mean age: 59.08 ± 8.94years old, male: 49.9%) from CHARLS were included. Participants with pre-frailty or frailty status had a higher risk of developing CKD compared with robust participants (pre-frail vs robust, OR 1.78, 95% CI 1.37-2.32, p < 0.001; frail vs robust, OR 2.52, 95% CI 1.67-3.79, p < 0.001). Participants who had a robust status in the two surveys had a significantly lower risk of developing CKD (OR 0.51, 95% CI 0.36-0.75, p < 0.001) compared with those who never had a robust status. Frailty status is significantly associated with the incidence of CKD. The risk of CKD was lower in those who ever had a robust status than in participants who never had a robust status.

Clinical Comorbidities and Videourodynamic Characteristics of Dysfunctional Voiding in Women

Purpose: The current study aimed to investigate the clinical comorbidities and urodynamic characteristics of a large cohort of women with dysfunctional voiding (DV) validated on a videourodynamic study (VUDS). Methods: Women who presented with VUDS-confirmed DV from 1998 to 2022 were retrospectively analyzed. Data on clinical symptoms, VUDS findings, and medical comorbidities including medical illness and previous surgical history were recorded and examined. Patients with DV were subgrouped according to age, presence of medical comorbidity, and different urodynamic parameters. The urodynamic parameters and treatment outcomes among the different subgroups were examined. Results: In total, 216 women were retrospectively analyzed. Among them, 188 (88.3%) presented with storage symptoms and 130 (61.0%) with voiding symptoms. Regarding outcomes, 48 (22.2%) patients had successful treatment outcomes; 76 (35.2%), improved outcomes; and 92 (42.6%), failed outcomes. Then, 150 (69.0%) patients presented with urodynamic DO. Patients with terminal DO experienced a significantly higher incidence of hypertension (56.8%), diabetes mellitus (37.9%), and latent central nervous system diseases (38.9%) than those with non-DO or phasic DO. Patients with phasic DO had a significantly higher detrusor pressure (Pdet) and bladder outlet obstruction index than those with non-DO and terminal DO. Patients with hypertension or those with a Pdet ≥ 35 cmH2O had high rates of successful treatment outcomes. Conclusions: DV is significantly associated with older age and a higher incidence of central nervous system diseases, hypertension, and diabetes mellitus in women. Patients with phasic DO had a high Pdet and BOO, and patients with hypertension or those with Pdet ≥35 cm H2O who received urethral sphincter treatment had a better treatment outcome.

Jackfruit Bronzing Disease Surveillance Study in Selected Orchards of Peninsular Malaysia

Purpose: IIn Malaysia, jackfruit (variety Tekam Yellow) significantly contributes to the nation’s economy. The valuable fruit production is affected by jackfruit bronzing disease (JBD). Information on JBD occurrence in Peninsular Malaysia is necessary to develop effective disease control strategies. Hence, this study aimed to survey JBD occurrence and identify the corresponding causative pathogens in selected jackfruit orchards distributed in Peninsular Malaysia.Research Method: A total of eight jackfruit orchards from five states in Peninsular Malaysia were selected for JBD sampling. Fruit samples were described for characteristic symptoms and disease incidence was expressed in percentage. The causative pathogens were identified using morphological observation and molecular methods while the pathogenicity test was done using Koch’s Postulates.Findings: JBD incidence in Peninsular Malaysia ranged between 20.13-70.25%. JBD-causal pathogen isolation showed that the bacterium was gram-negative, oxidase-negative, and non-capsulated straight rod shape with an average size of 0.35 x 1.31 μm (facultative anaerobic). A DNA sequence analysis on the 16S rRNA gene indicated that 15 putative isolates were unique to P. stewartii and one to P. dispersal at a 99-100% similarity index. Pathogenicity test of the P. stewartii isolates showed JBD characteristic symptoms suggesting that JBD occurrence caused by P. stewartii is common in Peninsular Malaysia and the pathogen could co-exist with P. dispersa.Research Limitations: The number of orchards sampled in this study is low and therefore, the findings pose biases to a certain extent.Originality/Value: JBD occurrence is common in small jackfruit orchards in Peninsular Malaysia.

Disease burden of communicable diseases among children and adolescents aged under 20 years in China from 1990 to 2021

To investigate the epidemiological characteristics and changing trends of communicable diseases among children and adolescents in China from 1990 to 2021. Based on the Global Burden of Disease Database, epidemiological indicators for communicable diseases among the population aged under 20 years in China from 1990 to 2021 were selected to analyze the burden of communicable diseases in this population, and a comparative analysis was performed with global data as well as data from Western Europe and North America. In 1990-2021, the overall burden of communicable diseases tended to decrease among children and adolescents in China. In 2021, the prevalence rate of communicable diseases in China was lower than the global prevalence rate and was higher than that in Western Europe and North America. There was a significant reduction in the mortality rate of communicable diseases, and the gap with Western Europe and North America gradually narrowed year by year. The overall incidence rate, mortality rate, and disability-adjusted life year rate of communicable diseases in males were higher than those in females, and respiratory infections and intestinal infections were more common in children aged <5 years, while the incidence rate of sexually transmitted diseases was higher in adolescents. From 1990 to 2021, the disease burden of communicable diseases among the population under 20 years old in China has significantly decreased. However, there is still a certain gap compared to developed regions. Strengthening the prevention and control of diseases such as respiratory infections and acquired immunodeficiency syndrome, as well as enhancing health interventions for children under 5 years old, will help improve the overall health level of children and adolescents in China.

Einfluss von Gender auf Parodontitis: Prävention, Prävalenz und Ätiologie in einer narrativen Übersicht

Periodontitis leads to a destruction of the tooth-supporting apparatus, which untreated may end up in tooth-loss. Key factor in the pathogenesis of periodontitis is the host immune response, genetic predisposition, and lifestyle factors (such as smoking, stress, and diabetes), all of which influence disease severity. Periodontitis is more common in men than women, this fact may point out that gender may have an influence on periodontitis. In addition, the incidence and severity seem to have a gender predilection with the incidence and severity of periodontal disease appearing to be greater in males than in females. The purpose of this narrative review was to summarize the existing literature on influence of gender in periodontology. The review included German and English articles and aimed to identify any gender differences in periodontitis. The World Health Organization (WHO) defines gender as the socially constructed characteristics, norms, behaviors and roles associated with being a woman, man, girl or boy, and the relationships between them. The topic of "gender" is not a new topic in dentistry. However, existing studies are relatively limited and further research is needed to improve our understanding of this topic. In fact, understanding gender and gender differences in oral health may be valuable for improving the effectiveness of preventive and therapeutic interventions. By recognizing and addressing these differences, healthcare professionals can tailor their approaches to better address the specific needs and challenges of individuals of different genders. This can help improve overall oral health outcomes.

A CLINICAL COMPARATIVE STUDY OF RENAL PARAMETERS OF OBESE AND HYPERTENSIVE PATIENTS WITH NON-OBESE HYPERTENSIVE PATIENTS

Objective: Obesity is associated with an early onset of glomerulomegaly, hemodynamic changes of a hyper-filtering kidney, and increased albuminuria. It is an important risk factor for incident CKD and increase risk of ESRD. The aim of the present study is to compare the influence of renal parameters among the obese and non-obese hypertensive patients attended to a tertiary care hospital. Methods: The study was conducted on 120 patients who were divided into 4 groups Group ‘O’ comprises of obese individuals; Group ‘OH’, which comprises of 30 obese and hypertensive individuals; Group ‘NO, H’ which comprises of non-obese and hypertensive individuals and Group ‘C’ which comprises of 30 healthy control group having normal BMI. Results: The mean±SD of serum creatinine was 0.88±0.06; 1.13±0.1; 0.7±0.08; 0.7±0.06 of all the 4 groups and the Serum urea mean±SD was 26.4±3.8; 36.6±5.42; 21.2±3.2; 20.4±3.2 and the Serum uric acid mean±SD levels were 4.3±0.64; 4.3±0.56; 3.8±0.3; 3.7±0.26 of all the 4 groups and eGFR values were 139.5±1.8; 95.3±23.20; 116.2±7.4;118.6±6.2 in obese, obese hypertensive, non-obese hypertensive and control subjects respectively. The results showed that there was a significant influence of renal parameters among the four tested groups. Conclusion: The strategies to prevent weight gain and to induce weight loss in patients who are already obese would ultimately reduce the incidence of obesity-mediated renal disease.
