Abstract
The purpose of this commentary on the special issue of Prevention Science, "International Responses to Prevention Intervention Research During Human Ecosystem Disruptions," is to review the six target articles included in this issue, evaluate their results, and highlight the myriad ways in which diverse teams of prevention scientists mobilized to conduct rigorous scientific research during major human ecosystem disruptions (HEDs). The articles included in this issue consider both the etiology of mental and behavioral health challenges (i.e., substance use, mental health, behavioral problems) during HEDs and preventive intervention efforts aimed at addressing these challenges (i.e., adaptation and implementation of evidence-based interventions in novel contexts). This commentary discusses each article with emphasis on the respective contributions that prevention science teams have made to public health during major HEDs. Even in the most challenging contexts, prevention scientists have been at the forefront of public health efforts and have evidenced the vital role of prevention science for public health during HED events. The commentary concludes by highlighting the critical roles that prevention scientists can play in addressing critical public health issues during large-scale HEDs.

Abstract
BACKGROUND Myopia, commonly known as near-sightedness, has emerged as a global epidemic, impacting almost one in three individuals across the world. The increasing prevalence of myopia during early childhood has heightened the risk of developing high myopia and related sight-threatening eye conditions in adulthood. This surge in myopia rates, occurring within a relatively stable genetic framework, underscores the profound influence of environmental and lifestyle factors on this condition. In this comprehensive narrative review, we shed light on both established and potential environmental and lifestyle contributors that affect the development and progression of myopia. MAIN BODY Epidemiological and interventional research has consistently revealed a compelling connection between increased outdoor time and a decreased risk of myopia in children. This protective effect may primarily be attributed to exposure to the characteristics of natural light (i.e., sunlight) and the release of retinal dopamine. Conversely, irrespective of outdoor time, excessive engagement in near work can further worsen the onset of myopia. While the exact mechanisms behind this exacerbation are not fully comprehended, it appears to involve shifts in relative peripheral refraction, the overstimulation of accommodation, or a complex interplay of these factors, leading to issues like retinal image defocus, blur, and chromatic aberration. Other potential factors like the spatial frequency of the visual environment, circadian rhythm, sleep, nutrition, smoking, socio-economic status, and education have debatable independent influences on myopia development. CONCLUSION The environment exerts a significant influence on the development and progression of myopia. Improving the modifiable key environmental predictors like time spent outdoors and engagement in near work can prevent or slow the progression of myopia. The intricate connections between lifestyle and environmental factors often obscure research findings, making it challenging to disentangle their individual effects. This complexity underscores the necessity for prospective studies that employ objective assessments, such as quantifying light exposure and near work, among others. These studies are crucial for gaining a more comprehensive understanding of how various environmental factors can be modified to prevent or slow the progression of myopia.

Abstract
BACKGROUND In a recent genome-wide association study, novel genetic variations of WNT9A were reported to be involved in the etiopathogenesis of thumb osteoarthritis (TOA) in Caucasians. Our purposes were to replicate the association of WNT9A with the development of TOA in the Chinese population and to further unveil the functional role of the risk variants. METHODS SNP rs11588850 of WNT9A were genotyped in 953 TOA patients and 1124 healthy controls. The differences of genotype and allele distributions between the patients and healthy controls were evaluated using the Chi-square test. Luciferase Reporter Assay was performed to investigate the influence of variant on the gene expression. RESULTS There was significantly lower frequency of genotype AA in TOA patients than in the controls 74.9% vs. 81.9%, p < 0.001). The frequency of allele A was remarkably lower in the patients than in the controls (86.3% vs. 90.5%, p < 0.001), with an odds ratio of 0.66 (95% CI = 0.54-0.80). Luciferase Reporter Assay showed that the construct containing mutant allele G of rs11588850 displayed 29.1% higher enhancer activity than the wild allele A construct (p < 0.05). CONCLUSIONS Allele G of rs11588850 was associated with the increased risk of TOA possibly via up-regulation of WNT9A expression. Further functional analysis into the regulatory role of rs11588850 in WNT9A expression can shed new light on the genetic architecture of TOA.

Abstract
Spain is the second largest onion-producing country in Europe with 1,465,430 tons and an export value of 584 million € in 2021 (MAPA 2022). In summer 2022 rot bulb symptoms were observed in five commercial fields and during the storage of cultivars 'Orlenda', 'Veleta', 'Mallory', 'Citation' and 'Pantano' from La Roda in Albacete (Castilla-La Mancha, Spain). Approximately 20% of sampled bulbs (113 bulbs analyzed) were affected with dry scales showing brown to dark brown rot on the top and basal plate of the onion bulbs. Occasionally, white to light pink fungal mycelium was observed between rotten scales and the plate basal. Sections of dry scales (5-10 mm) of the apical and basal plate were cut and placed on potato dextrose agar (PDA) and Komada medium (Komada 1975). From 5-day-old cultures typical white to light pink mycelium with microconidia in chains formed on polyphialides and macroconidia resembling Fusarium proliferatum (Nelson et al. 1983). To confirm the pathogen identity, partial translation elongation factor 1-alpha (TEF1) and RNA polymerase II subunit 2 (RPB2) genes were amplified and sequenced using primers reported in O´Donnell et al. (1998) and Samuels et al. (2002) for TEF1 and Liu et al. (1999) for RPB2. In BLAST analyses, the sequences showed 100% identity to the corresponding region of F. proliferatum (KP964908 and JF740801). Sequences were submitted to GenBank, and registered accession numbers are OR061014-16 for TEF1 and OR061017-19 for RPB2. Pathogenicity tests were conducted by inoculating healthy onion bulbs (five replicates per treatment) on the apical and basal plate by placing a 7-day old mycelial plug (10 mm diameter) from PDA cultures. Two onion cultivars ('Pandero' by Nunhems USA and 'Mallory' by Bejo The Netherlands) were inoculated separately with three isolates (PRO1, PRO9, PRO12). Control bulbs were inoculated with sterile PDA. The experiment was carried out twice. All bulbs were placed in a moist chamber and incubated at 25°C in the dark. After 15 days, bulbs inoculated with mycelial plugs showed similar symptoms to those of the original diseased bulbs. Browning dry rot was observed on the apical and basal plate of bulbs. When bulbs were cut longitudinally inner progressing rot was observed. Control bulbs remained symptomless. In both experiments, F. proliferatum was successfully re-isolated and morphologically confirmed from symptomatic bulbs to fulfill Koch's postulates. These results confirmed that isolates PRO1, PRO9 and PRO12 were the pathogen causing basal and dry rot on onion bulbs. This pathogen has recently been identified in China on Allium cepa L. var. agrogatum (Liu et al. 2022) and Idaho on onion (Beck et al. 2020) and could become a serious threat to onion production in Spain, reducing the quality and yield of onion.

Abstract
Roselle (Hibiscus sabdariffa L.) is a crop of economic importance, refreshing drinks are prepared from its calyces, it is also attributed to antioxidant, antibacterial, and antihypertensive properties (Da-Costa-Rocha et al. 2014). In November 2022, in municipality of Iguala (18.355592N, 99.548546W, 749 m above sea level), Guerrero, México, roselle plants of approximately 1.5 months of age with basal rot were detected under greenhouse conditions. The symptoms consisted of wilting, yellowing, and root and stem rot with constriction in the base of the stem. The symptoms were detected in approximately 15% of plants at the operation. From symptomatic tissue, cuts were made into approximately 0.5 cm pieces, sterilized with 2% NaClO, washed with sterile distilled water, transferred to PDA medium amended with 50 mg/liter of Chloramphenicol, and incubated in the dark for four days at 28 °C. Rhizoctonia-like colonies were consistently obtained, and nine isolates were selected and purified by the hyphal-tip method. After four days, isolates developed a mycelium was light-white that became brown with age. Right-angled hyphal branching was also observed, in addition to a slight constriction at the base of the branches. In some older cultures, numerous dark brown sclerotia were observed. They were multinucleate cell with three to eight nuclei and measured from 1 to 2 mm in diameter. Together these characteristics were consistent with the description of Rhizoctonia solani Kühn (Parmeter 1970). The anastomosis group (AG) was confirmed by amplifying the ITS region with the primers ITS1 and ITS4 (White et al. 1990) of the RIJAM3 and RIJAM5 strains. The sequences were deposited in GenBank (Nos. OR364496 and OR364497 for RIJAM3 and RIJAM5, respectively). BLAST analysis, both isolates indicated 99.7 identity to R. solani AG-4 HG-I (GenBank: KM013470) strain ICMP 20043 (Ireland et al. 2015). The phylogenetic analysis of AGs sequences allowed assignment of isolates RIJAM3 and RIJAM5 to the AG-4 HG-1 clade. A pathogenicity test was performed on 20 one-month-old roselle plants. Mycelium of RIJAM3 isolate was inserted into the base of the stem with a sterile toothpick. As a control, a sterile toothpick with no mycelium was inserted in ten healthy plants. Additionally, 50 eight-day-old seedlings were inoculated by placing a 5-mm diameter agar plug colonized with mycelium of RIJAM3 at the base of the stem 10 mm below the soil surface. As control treatments, uncolonized PDA plugs were deposited at the base of 25 seedlings. The inoculated plants were incubated in a greenhouse with an average temperature and relative humidity of 28°C and 85%, respectively. Following inoculation, symptoms similar to those observed in the original outbreak were observed in plants after six days and only after four days in seedlings. In both experiments, the control plants and seedlings remained asymptomatic. R. solani was re-isolated from plants and seedlings, complying with Koch's postulates. The pathogenicity testing was repeated twice, with concordant results. In Nigeria and Malaysia R. solani was reported to seedling death to cause seedling dieback in roselle (Adeniji 1970; Eslaminejad and Zakaria 2011). In México R. solani AG-4 has been previously reported in crops of potato, chili and tomato (Montero-Tavera et al. 2013; Ortega-Acosta et al. 2022; Virgen-Calleros et al. 2000). To the best of our knowledge, this is the first report of R. solani AG-4 HG-I as a causing of root and basal stem rot on roselle in Mexico. This research provides information essential for informing the management of this disease, and may help design measures to prevent the spread of the pathogen to other regions.

Abstract
BACKGROUND Observational studies have explored the association of psychiatric disorders and the risk of brain cancers. However, the causal effect of specific mental illness on glioma remains elusive due to the lack of solid evidence. METHODS We performed a two-sample bidirectional Mendelian randomization (MR) analysis to explore the causal relationships between 5 common psychiatric disorders (schizophrenia, major depressive disorder, bipolar disorder, autism spectrum disorder, and panic disorder) and glioma. Summary statistics for psychiatric disorders and glioma were extracted from Psychiatric Genomics Consortium (PGC) and 8 genome-wide association study (GWAS) datasets respectively. We calculated the MR estimates for odds ratio of glioma associated with each psychiatric disorder by using inverse-variance weighting (IVW) method. Sensitivity analyses such as weighted median estimator, MR-Egger and MR-PRESSO were leveraged to assess the strength of causal inference. RESULTS A total of 30,657 participants of European ancestry were included in this study. After correction for multiple testing, we found that genetically predicted schizophrenia was associated with a statistically significant increase in odds of non-glioblastoma multiforme (non-GBM) (OR = 1.13, 95% CI: 1.03-1.23, P = 0.0096). There is little evidence for the causal relationships between the other 4 psychiatric disorders with the risk of glioma. CONCLUSIONS In this MR analysis, we revealed an increased risk of non-GBM glioma in individuals with schizophrenia, which gives an insight into the etiology of glioma.

Abstract
Objective: To elucidate the epidemiological characteristics and changing trends of liver failure in order to provide evidence-based strategies for prevention and treatment. Methods: The epidemiological information of inpatients with liver failure admitted and treated at Beijing You'an Hospital from 2012 to 2021 was retrospectively collected. The trend test was used to analyze age, gender, as well as the year-by-year changes in the underlying acute and chronic etiology of acute liver failure (ALF), sub-acute liver failure (SALF), acute-on-chronic liver failure (ACLF), and chronic liver failure (CLF). Results: During the study period, information on a total of 8512 inpatients, aged 51.3±13.5 years and mainly male (71.9%) with liver failure, was collected. The highest to lowest proportions of liver failure types were ACLF 4 023 (47.3%), CLF 3 571(42.0%), SALF 670 (7.9%), and ALF 248 (2.9%). The top five causes of liver failure in the overall population, accounting for 87.6% of the total, were hepatitis B 3 199 (37.58%), alcoholic liver disease 2 237 (26.28%), cryptogenic liver disease 906(10.61%), hepatitis B + alcoholic liver disease 603 (7.08%), drugs 488 (5.73%), The top three etiologies of patients with different types of liver failure were acute etiologies for acute liver failure (ALF), followed by drugs 107 (43.1%), hepatitis B 47(19.0%), and unknown etiology 36 (14.5%); sub-acute liver failure (SALF), followed by drugs 381(56.9%), unknown etiology 106 (15.8%), and sepsis 56 (8.4%); and acute-on-chronic liver failure (ACLF), followed by drugs 2 092(52.0%), alcoholic liver disease 813(20.2%), and cryptogenic liver disease 398(9.9%); and chronic etiologies for chronic liver failure (CLF), followed by alcoholic liver disease 1 410(39.5%), hepatitis B 1 028(28.8%), and cryptogenic liver disease 364(10.2%). Longitudinal analysis showed that the average age of patients with liver failure increased year by year, but the sex ratio trend did not change significantly, with male patients predominating throughout. The proportion of drug-induced liver failure in patients with ALF and SALF increased year by year, and the difference in the trend test was statistically significant (P < 0.05). The proportion of patients with chronic etiologies of ACLF and CLF decreased year by year among hepatitis B, while the proportion of alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease increased year by year (the difference was statistically significant, P < 0.05). Conclusion: The etiological spectrum of liver failure is changing in our country. Although hepatitis B is still the main cause of liver failure, its proportion shows a decreasing trend year by year, with the exception of ACLF, which is no longer the primary etiology of other types of liver failure, while drug-induced liver disease, alcoholic liver disease, autoimmune liver disease, and cryptogenic liver disease are increasing year by year and will become the focus of liver disease prevention and treatment in the future.

Abstract
Background and Aim This study aimed to identify the indications for liver transplantation (LT) based on underlying etiology and to characterize the patients who underwent LT. Materials and Methods We conducted a multicenter cross-sectional observational study across 11 tertiary centers in Turkiye from 2010 to 2020. The study included 5,080 adult patients. Results The mean age of patients was 50.3±15.2 years, with a predominance of female patients (70%). Chronic viral hepatitis (46%) was the leading etiological factor, with Hepatitis B virus infection at 35%, followed by cryptogenic cirrhosis (24%), Hepatitis C virus infection (8%), and alcohol-related liver disease (ALD) (6%). Post-2015, there was a significant increase in both the number of liver transplants and the proportion of living donor liver transplants (p<0.001). A comparative analysis of patient characteristics before and after 2015 showed a significant decline in viral hepatitis-related LT (p<0.001), whereas fatty liver disease-related LT significantly increased (p<0.001). Conclusion Chronic viral hepatitis continues to be the primary indication for LT in Turkiye. However, the proportions of non-alcoholic fatty liver disease (NAFLD) and ALD-related LT have seen an upward trend over the years.

Abstract
BACKGROUND Patellofemoral pain (PFP) is among the most common injuries in runners. While multiple risk factors for patellofemoral pain have been investigated, the interactions of variables contributing to this condition have not been explored. This study aimed to classify runners with patellofemoral pain using a combination of factors including biomechanical, anthropometric, and demographic factors through a Classification and Regression Tree analysis. RESULTS Thirty-eight runners with PFP and 38 healthy controls (CON) were selected with mean (standard deviation) age 33 (16) years old and body mass index 22.3 (2.6) kg/m2. Each ran at self-selected speed, but no between-group difference was identified (PFP = 2.54 (0.2) m/s x CON = 2.55 (0.1) m/s, P = .660). Runners with patellofemoral pain had different patterns of interactions involving braking ground reaction force impulse, contact time, vertical average loading rate, and age. The classification and regression tree model classified 84.2% of runners with patellofemoral pain, and 78.9% of healthy controls. The prevalence ratios ranged from 0.06 (95% confidence interval: 0.02-0.23) to 9.86 (95% confidence interval: 1.16-83.34). The strongest model identified runners with patellofemoral pain as having higher braking ground reaction force impulse, lower contact times, higher vertical average loading rate, and older age. The receiver operating characteristic curve demonstrated high accuracy at 0.83 (95% confidence interval: 0.74-0.93; standard error: 0.04; P < .001). CONCLUSIONS The classification and regression tree model identified an influence of multiple factors associated with patellofemoral pain in runners. Future studies may clarify whether addressing modifiable biomechanical factors may address this form of injury.

Abstract
In August 2021, severe leaf blight symptoms were observed on onion (Allium cepa L. cvs Francia and Askari F1 hybrid) in commercial fields located in Mauritius, namely La Forêt (20°19'56.1"S57°30'04.9"E), St Aubin (20°29'47.0"S57°32'29.4"E) and Chapiron (20°20'46.8"S 57°29'12.8"E). Infected leaves displayed small circular to oblong yellow-pale-brown and spindle shaped lesions which later coalesced and formed necrotic areas with black sporulation. Three fields were selected from each region, and along a W-pattern across the fields a disease incidence ranging 53-93% and a severity of 9-28% were recorded. Ten symptomatic leaves were collected in each region and small pieces of infected tissue were surface disinfected using 1% NaOCl for 2 min, rinsed with sterile distilled water, air-dried, transferred to potato dextrose agar (PDA) and incubated for 7 days at 20°C under a 12-h light/dark cycle. Fungal cultures with uniform appearance forming multi-septated conidia typical of the genus Stemphylium (Simmons 1969) were consistently isolated. Monosporic colony of isolates SVCWLF24/3, SVSSA23/1 and SVCWLMC26/1 developed similar olivaceous green to light and dark grey mycelium with an average daily growth rate of 6.5 mm at 25°C in the dark. Conidiophores were straight, light brown with a distinct swollen apex on which olive brown to dark brown, oblong to ovoid, septate conidia formed with dimensions 16.2-44.7 × 8.0-22.9 μm (av. 29.5 x 14.7 μm; n = 50) typical of Stemphylium vesicarium (Wallr) E.G. Simmons 1969 (Woudenberg et al. 2017). Genomic DNA of the three isolates was extracted from fungal mycelium (Ranghoo and Hyde 2000).. The ITS, cmdA and gapdh genes of the isolates were amplified with primers ITS4/ITS5 (White et al. 1990), CALDF1/CALDR1 (Lawrence et al. 2013) and Gpd1/Gpd2 (Beerbee et al. 1999) and sequenced. Sequences were submitted to GenBank under accession numbers OR131271, ON620213, OR188702 (ITS), OR350623, OR350622, OR166368 (cmdA) and OR684516, OR684517, OR684518 (Gapdh). The BLAST search of the sequences showed 100% similarity with S. vesicarium strain CBS 155.24 under accession numbers KU850555 (ITS), KU850702 (Gapdh) and KU850845 (cmdA) (Woudenberg et al. 2017). Phylogenetic trees inferred from the ITS, cmdA and Gapdh concatenated datasets with the maximum-likelihood algorithm allowed clustering of the isolates within S. vesicarium clade, confirming the morphological identification. Pathogenicity tests were performed using all three isolates, cultured on PDA at 25°C in a 12-h dark/light cycle. Ten 60-day-old onion plants (cv. Francia) were spray inoculated each with 10 ml of conidial suspension (1 × 104/ml) of each isolate while 10 healthy plants sprayed with sterile distilled water served as control. They were incubated in a greenhouse at 25°C with a 12-h photoperiod and > 80% humidity. Necrotic circular lesions appeared on leaves after 7-10 days while control plants remained symptomless. Re-isolations made from symptomatic leaf tissues on PDA consistently yielded cultures with similar morphology as the original isolates, thus fulfilling Koch's postulates. This is the first report of S. vesicarium as the causal agent of leaf blight of onion in Mauritius. It is a re-emerging fungal disease (Hay et al. 2021) with a wide host range threatening local onion production. This finding will contribute to early detection of leaf blight, implementation of surveillance and integrated disease management in affected regions.

Abstract
BACKGROUND This study examined the characteristics and outcomes of surgical aortic valve replacement (SAVR) both isolated and in combination with other cardiac surgery in Malaysia from 2015 to 2021. METHODS This was a retrospective study of 1346 patients analyzed on the basis of medical records, echocardiograms and surgical reports. The overall sample was both considered as a whole and divided into aortic stenosis (AS)/aortic regurgitation (AR)-predominant and similar-severity subgroups. RESULTS The most common diagnosis was severe AS (34.6%), with the 3 most common etiologies being bicuspid valve degeneration (45.3%), trileaflet valve degeneration (36.3%) and rheumatic valve disease (12.2%). The second most common diagnosis was severe AR (25.5%), with the most common etiologies being root dilatation (21.0%), infective endocarditis (IE) (16.6%) and fused prolapse (12.2%). Rheumatic valve disease was the most common mixed disease. A total of 54.5% had AS-predominant pathology (3 most common etiologies: bicuspid valve degeneration valve, degenerative trileaflet valve and rheumatic valve disease), 36.9% had AR-predominant pathology (top etiologies: root dilatation, rheumatic valve disease and IE), and 8.6% had similar severity of AS and AR. Overall, 62.9% of patients had trileaflet valve morphology, 33.3% bicuspid, 0.6% unicuspid and 0.3% quadricuspid. For AS, the majority were high-gradient severe AS (49.9%), followed by normal-flow low-gradient (LG) severe AS (10.0%), paradoxical low-flow (LF)-LG severe AS (6.4%) and classical LF-LG severe AS (6.1%). The overall in-hospital and total 1-year mortality rates were 6.4% and 14.8%, respectively. Pure severe AS had the highest mortality. For AS-predominant pathology, the etiology with the highest mortality was trileaflet valve degeneration; for AR-predominant pathology, it was dissection. The overall survival probability at 5 years was 79.5% in all patients, 75.7% in the AS-predominant subgroup, 83.3% in the AR-predominant subgroup, and 87.3% in the similar-severity subgroup. CONCLUSIONS The 3 most common causes of AS- predominant patients undergoing SAVR is bicuspid valve degeneration, degenerative trileaflet valve and rheumatic and for AR-predominant is root dilatation, rheumatic and IE. Rheumatic valve disease is an important etiology in our SAVR patients especially in mixed aortic valve disease. Study registration IJNREC/562/2022.

Abstract
Primary sclerosing cholangitis (PSC) was declared one of the biggest unmet needs in hepatology during International Liver Congress 2016 in Berlin. Since then, not much has changed unfortunately, largely due to the still elusive pathophysiology of the disease. One of the most striking features of PSC is its association with inflammatory bowel disease (IBD), with the majority of patients with PSC being diagnosed with extensive colitis. This review describes the epidemiology of IBD in PSC, its specific phenotype, complications and potential pathophysiological mechanisms connecting the two diseases. Whether PSC is merely an extra-intestinal manifestation of IBD or if PSC and IBD are two distinct diseases that happen to share a common susceptibility that leads to a dual phenotype is debated. Implications for the management of the two diseases together are also discussed. Overall, this review summarises the available data in PSC-IBD and discusses whether PSC and IBD are one or two disease(s).

Abstract
Among the premenopausal women, Polycystic Ovary Syndrome (PCOS) is the most prevalent endocrinopathy affecting the reproductive system and metabolic rhythms leading to disrupted menstrual cycle. Being heterogeneous in nature it is characterized by complex symptomology of oligomennorhoea, excess of androgens triggering masculine phenotypic appearance and/or multiple follicular ovaries. The etiology of this complex disorder remains somewhat doubtful and the researchers hypothesize multisystem links in the pathogenesis of this disease. In this review, we attempt to present several hypotheses that tend to contribute to the etiology of PCOS. Metabolic inflexibility, aberrant pattern of gonadotropin signaling along with the evolutionary, genetic and environmental factors have been discussed. Considered a lifelong endocrinological implication, no universal treatment is available for PCOS so far however; multiple drug therapy is often advised along with simple life style intervention is mainly advised to manage its cardinal symptoms. Here we aimed to present a summarized view of pathophysiological links of PCOS with potential therapeutic strategies.

Abstract
Objective To determine the etiologies and outcomes of liver disease in pregnancy in a developing country. Method A total of 336 consecutive pregnant women with liver disease were included in this prospective cohort study conducted at the Department of Gastroenterology, Jinnah Postgraduate Medical Center, Karachi from August 2019 to August 2021. Patients' baseline demographic, clinical, and laboratory data and outcomes were collected on a pre-designed questionnaire. Results Among all the pregnant females, the most common liver disease was acute hepatitis E virus (HEV) infection (37.2%), followed by preeclampsia (PEC)/eclampsia (EC), hemolysis, elevated liver enzymes & low platelets (HELLP) syndrome, and hyperemesis gravidarum (HG). The most common maternal complications were fulminant hepatic failure (FHF) in 14.9% and placental abruption in 11.0%. Fetal complications included intrauterine death (IUD) in 20.8% and preterm birth in 8.6%. The maternal and neonatal mortality rates were 11.6% and 39.6%, respectively. Among the predictors, low maternal weight, low body mass index (BMI), and low hemoglobin (Hb) were associated with increased maternal mortality. Low fetal weight, height, maternal systolic blood pressure (SBP), and low maternal Hb were independent predictors of fetal mortality. Conclusion In our cohort of pregnant females in a tertiary care medical center, acute HEV was the most common liver disease, followed by PEC/EC, HELLP, and HG. Maternal and fetal deaths were alarming in this group of patients and demanded careful management.

METHODS Nineteen tonsillar tissues from PTH patients and 21 tissues from control patients were collected. Metagenomic sequencing was used to compare the microbiota in PTH and control groups. Alpha diversity indices were used to compare the richness and evenness of the microbiota between the two groups. PCoA and NMDS analyses were used to evaluate beta diversity. LDA analysis was conducted to identify significantly abundant genera. RESULTS No significant difference in alpha diversity indices was found between PTH and control patients. The dominant bacteria in the tonsillar microbiota were Haemophilus, Streptococcus, and Fusobacterium. PCoA and NMDS analyses showed significant differences in beta diversity between PTH and control patients. PTH patients had a significantly higher relative abundance of Neisseria, Capnocytophaga, and Veillonella. Capnocytophaga was also identified as a significantly abundant genus by LDA analysis. CONCLUSION This study demonstrates that there is a difference in the tonsillar microbiota between PTH and control patients. The results suggest that Neisseria, Capnocytophaga, and Veillonella may be associated with the development of PTH. These findings provide new insights into the potential role of the tonsillar microbiota in the development of PTH, and may help to develop new strategies for preventing and treating this potentially life-threatening complication.

Abstract
Hepatocellular carcinoma (HCC) is one of the most common cancers with a high mortality rate. HCC development is associated with its underlying etiologies, mostly caused by infection of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV), alcohol, non-alcoholic fatty liver disease, and exposure to aflatoxins. These variables, together with human genetic susceptibility, contribute to HCC molecular heterogeneity, including at the cellular level. HCC initiation, tumor recurrence, and drug resistance rates have been attributed to the presence of liver cancer stem cells (CSC). This review summarizes available data regarding whether various HCC etiologies may be associated to the appearance of CSC biomarkers. It also described the genetic variations of tumoral tissues obtained from Western and Eastern populations, in particular to the oncogenic effect of HBV in the human genome.

Abstract
INTRODUCTION The incidence of tibial plateau fractures (TPF) is 1% of all fractures and increases with age. Whether non-operatively or operatively treated, complications (infection, malalignment, loss of reduction and delayed union or nonunion) and post-traumatic osteoarthritis are not uncommon, and the risk for complications has generally been assumed to rise with age. This study investigated all post-TPF complications and secondary surgery after non-operative and operative treatment. Secondary aims were to determine the incidence and epidemiology of TPF in the population of the Central Finland region. MATERIALS AND METHODS All patients over age 18 years with a TPF, including incidence, etiology, fracture type, and possible complications and reoperations, sustained during the period 1998-2019 were retrospectively identified from hospital records. RESULTS The annual mean incidence of TPF was 14.4/100,000, with older women at highest risk. The proportions of non-operative and operatively treated patients who had undergone at least one additional surgical operation were 6% and 26%, respectively. Age and female gender were identified as risk factors for complications and secondary operations. The risk peaked in patients aged 60-65 years, decreasing thereafter. Non-operative treatment showed low risk for both non-union and loss of reduction. CONCLUSIONS Older women were at the highest risk for TPF and for subsequent complications and secondary operations after TPF. Secondary operations after operatively treated TPF were not uncommon and patients aged 60-65 years were at highest risk. Given the low rates of complications and re-operations, non-operative treatment may be a safe option in cases of all minimally displaced TPF.

Abstract
Considerable progress has been made in elucidating the relationships between early life psychobiological and environmental risk factors and the development of tobacco addiction. However, a comprehensive understanding of the heterogeneity in tobacco addiction phenotypes requires integrating research findings. The probabilistic epigenesis meta-theory offers a valuable framework for this integration, considering systemic, multilevel, developmental, and evolutionary perspectives. In this paper, we critically review relevant research on early developmental risks associated with tobacco addiction and highlight the integrative heuristic value of the probabilistic epigenesis framework for this research. For this, we propose a four-level systems approach as an initial step towards integration, analyzing complex interactions among different levels of influence. Additionally, we explore a coaction approach to examine key interactions between early risk factors. Moreover, we introduce developmental pathways to understand interindividual differences in tobacco addiction risk during development. This integrative approach holds promise for advancing our understanding of tobacco addiction etiology and informing potentially effective intervention strategies.

Abstract
BACKGROUND The worldwide incidence of acute pancreatitis (AP) is increasing, but the dominant etiology of AP may vary by country. Mixed etiologies are involved in the increase in the number of AP patients. AIMS This study was to analyze the etiological changes and prognosis of AP patients and explore the prognosis of AP patients with mixed etiologies. METHODS Using a retrospective analysis method, AP patients hospitalized from January 2007 to December 2021 were selected from a pancreatic center in Nanchang, China. Trends in the main etiologies were analyzed, and the severity and prognosis of different etiologies were compared. RESULTS A total of 10,071 patients were included. Cholelithiasis (56.0%), hyperlipidemia (25.3%), and alcohol (6.5%) were the top three etiologies. The proportion of acute biliary pancreatitis (ABP) showed a decreasing trend, while the proportion of hypertriglyceridemic pancreatitis (HTGP) and alcoholic AP showed an increasing trend (all ptrend < 0.001). The incidence of organ failure and necrotizing pancreatitis was higher in patients with HTGP than in those with AP induced by other etiologies (all p < 0.05). There was no statistically significant difference in mortality among patients with different etiologies. Patients with AP due to a mixed hypertriglyceridemia-alcoholic etiology had higher ICU admission rates and were more severe than those with AP induced by other mixed etiologies. CONCLUSION In the past 15 years, the proportion of ABP has trended downward, while those of HTGP and alcoholic AP have risen. Among patients with mixed etiologies, those with a mixed hypertriglyceridemia-alcoholic etiology had a worse prognosis.

Abstract
BACKGROUND Liver cirrhosis (LC) is a prevalent and severe disease in China. The burden of LC is changing with widespread vaccination of hepatitis B virus (HBV) and antiviral therapy. However, the recent transition in etiologies and clinical features of LC cases requiring hospitalization is unclear. AIM To identify the transition in etiologies and clinical characteristics of hospitalized LC patients in Southern China. METHODS In this retrospective, cross-sectional study we included LC inpatients admitted between January 2001 and December 2020. Medical data indicating etiological diagnosis and LC complications, and demographic, laboratory, and imaging data were collected from our hospital-based dataset. The etiologies of LC were mainly determined according to the discharge diagnosis, and upper gastrointestinal bleeding, ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, hepatocellular carcinoma (HCC), portal vein thrombosis, hepatorenal syndrome, and acute-on-chronic liver failure (ACLF) were considered LC-related complications in our study. Changing trends in the etiologies and clinical characteristics were investigated using logistic regression, and temporal trends in proportions of separated years were investigated using the Cochran-Armitage test. In-hospital prognosis and risk factors associated with in-hospital mortality were also investigated. RESULTS A total of 33143 patients were included in the study [mean (SD) age, 51.7 (11.9) years], and 82.2% were males. The mean age of the study population increased from 51.0 years in 2001-2010 to 52.0 years in 2011-2020 (P < 0.001), and the proportion of female patients increased from 16.7% in 2001-2010 to 18.2% in 2011-2020 (P = 0.003). LC patients in the decompensated stage at diagnosis decreased from 68.1% in 2001-2010 to 64.6% in 2011-2020 (P < 0.001), and the median score of model for end-stage liver disease also decreased from 14.0 to 11.0 (P < 0.001). HBV remained the major etiology of LC (75.0%) and the dominant cause of viral hepatitis-LC (94.5%) during the study period. However, the proportion of HBV-LC decreased from 82.4% in 2001-2005 to 74.2% in 2016-2020, and the proportion of viral hepatitis-LC decreased from 85.2% in 2001-2005 to 78.1% in 2016-2020 (both P for trend < 0.001). Meanwhile, the proportions of LC caused by alcoholic liver disease, autoimmune hepatitis and mixed etiology increased by 2.5%, 0.8% and 4.5%, respectively (all P for trend < 0.001). In-hospital mortality was stable at 1.0% in 2011-2020, whereas HCC and ACLF manifested the highest increases in prevalence among all LC complications (35.8% to 41.0% and 5.7% to 12.4%, respectively) and were associated with 6-fold and 4-fold increased risks of mortality (odds ratios: 6.03 and 4.22, respectively). CONCLUSION LC inpatients have experienced changes in age distribution and etiologies of cirrhosis over the last 20 years in Southern China. HCC and ACLF are associated with the highest risk of in-hospital mortality among LC complications.

Abstract
In México, avocado production is an important economic source. In the last season it generated $ 3. 27 billion USD of foreign currency in the country. Irpex spp. are wood decay fungi. In the period 2019-2022, in the state of Michoacán (19°13' N; 101°55' W), México, basidiomes of Irpex sp. were observed on the base of trunks and crowns of 5-years-old and older avocado (Persea americana) trees. The trees exhibited disease symptoms that included white root rot, leaf yellowing, small leaves, branch diebacks, generalized defoliation, apical flaccidity, abundant but small sun burnt fruits due to the lack of foliage, and after 2-4 years of first disease appearance, the infected trees died. In the place where fungus was established, abundant white and cottony mycelium was formed, which caused trees decay. The incidence of the disease in the sampled orchards was estimated to be 30% per ha with 350 - 400 trees, which was determined through a simple sampling design focused on trees with signs and symptoms of the disease due to the phytopathogen. Samples of infected tissue (roots and stems) and fungal basidiomes were collected from 90 trees (5-6 per orchard). The symptomatic avocado trees studied were randomly selected from 17 orchards. For the fungal macroscopic characterization, the synoptic keys described by Gilbertson and Ryvarden (1986) and by Largent (1973) were used. The samples showed typical structures corresponding to Irpex sp., including rosettes, annual basidiomes, a system of monomitic hyphae, and subglobose basidiospores. In vitro fungal isolation from basidiomes and infected tree tissues was done according to the protocol of Agrios (2004). The fungal strains were maintained on PDA at 28 °C. At 16 days of incubation the colonies were opaque, whitish with fluffy and corky mycelium. Microscopic analysis of the fungus showed typical yellowish spores, with an ellipsoid shape of 3-4 x 4-5.5 µm (50 accounted structures per isolate [N=19]) and basidia of 20-25 x 4.5-5.5 µm (n=20 basidiomes). For molecular characterization, two molecular markers were used, the internal transcribed spacer rDNA-ITS1 5.8 rDNA-ITS2 (ITS; White et al. 1990) and the large ribosomal subunit (LSU; Vilgalys and Hester 1990). The PCR reaction was performed as described by Martínez-González et al. (2017). The consensus sequences were compared with those deposited in the NCBI-GenBank, using the BLASTN 2.2.19 tool (Zhang et al. 2000), the samples showed 99% match with the species, Irpex rosettiformis. GenBank accession numbers of the submitted isolates are summarized in supplementary Table 4. To test Koch's postulates, 3-months old avocado plants grown in greenhouse conditions were inoculated (n = 10 per each isolate [N= 19]) on the roots with 3 g of I. rosettiformis mycelium. The experiment was done twice with 20 non-inoculated plants as control. After 67 days, basidiomes (50 x 70 x 1.5 mm in average) were observed where the disease incidence was >77%, with subsequent tree decline. The pathogen was re-isolated in vitro in PDA and its identity was confirmed by morphological characteristics of mycelium. This work shows that I. rosettiformis is not only a wood decay fungus, but also a phytopathogen, the causative agent of white root rot disease in P. americana var. drymifolia, cultivar 'Hass', which establishes a precedent for monitoring and preventing its proliferation to other regions in the American continent and the world where nursery avocado seedlings are exported.

Abstract
Immunoglobulin A vasculitis (IgAV), also known as Henoch-Schönlein purpura, has complex etiology and pathogenesis which have not been fully clarified. The latest research shows that SARS-CoV-2 and related vaccines, human papilloma vaccine, and certain biological agents can also induce IgAV. Most studies believe that the formation of galactose-deficient IgA1 (Gd-IgA1) and Gd-IgA1-containing immune complex plays a crucial role in the pathogenesis of IgAV. It is hypothesized that the pathogenesis of IgAV is associated with the binding of IgA1 to anti-endothelial cell antibodies. In addition, genetics also constitutes a major focus of IgAV research. This article reviews the new advances in the etiology of IgAV and summarizes the role of Gd-IgA1, Gd-IgA1-containing immune complex, anti-endothelial antibody, IgA1 conjugates, T lymphocyte immunity, and genetic factors in the pathogenesis of IgAV.

Abstract
Background Limited evidence is available regarding the management of small bowel obstruction in the virgin abdomen (SBO-VA), with most studies excluding this entity. This study aims to assess the available data on the treatment outcomes and predictors of surgical intervention in SBO-VA. Methods A retrospective cross-sectional study was conducted between 2015 and 2021, including all diagnosed and managed cases of SBO-VA at Al-Nasar Hospital. Patients were divided according to the treatment approach into surgical or conservative groups. Preoperative laboratory and radiologic data were gathered and compared between groups. Results During the study period, 67 cases, primarily males (58.2%), with an average age of 52.2±14.4 years were assessed. Common comorbidities included diabetes (20.9%) and hypertension (16.4%). Key symptoms were rebound tenderness (82.1%) and abdominal tenderness (70.1%). The predominant etiology was adhesions (23.9%). About 46.2% received conservative treatment, 53.8% underwent urgent surgery. Conservative treatment failed in 9.4% of cases, and complications arose in 23.9%, with most being fever (17.9%). Factors necessitating surgical management included older age (58.8 ±11.7 vs 44.9 ±13.8 years, p<0.001), previous hospital admission (p<0.001), presence of abdominal tenderness (p=0.030), longer abdominal pain duration (4.0 ±0.9 vs 2.1 ±0.6 days, p<0.001), higher C- reactive protein (p= 0.033), higher white blood cell (p= 0.006), longer time to hospital presentation (75.3 ±17.2 vs 39.0 ±22.8 days, p= <0.001), small bowel thickness ≥3 cm (p=0.009), and reduced bowel enhancement (p <0.001) on computed tomography imaging. In surgical group, the need for ICU admission was higher and hospital stays were shorter than in conservative group and were statistically significant (p<0.05). Conclusion The main etiology of SBO-VA in our study was adhesions. Older age, previous hospital admission, longer abdominal pain duration, abdominal tenderness, increased inflammatory markers, and alarm signs on CT scans are the main factors for determining the need for urgent surgical exploration in patients with SBO-VA. To achieve prompt identification and intervention, it is crucial to maintain a high level of vigilance and awareness, even in individuals with no prior surgical history.

Abstract
BACKGROUND The occurrence of mandibular canine impaction and/ or transmigration is a rare clinical entity but diagnosis and treatment planning is of clinical significance. The associated etiological factors and the clinical guidelines for the management are still not clear. The aim of this systematic review was to summarize the available data to report the prevalence and identify the etiological factors, clinical features, and various treatment outcomes in patients with mandibular canine impaction and/or transmigration. METHODS The review protocol was registered in PROSPERO (CRD42021222566) and was conducted and reported according to the PRISMA and Cochrane Handbook / Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. A computerized search of studies published up to April 30, 2023, was conducted using the following databases: Medline, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Scopus, Web of Science, and Latin American and Caribbean Health Sciences Literature. A manual search of the reference and citation lists of eligible articles and existing systematic reviews for any additions were also conducted. The Newcastle-Ottawa Scale quality assessment tool was used to assess the studies' quality. RESULTS After removing 6 duplicates, 3700 articles were identified. For the final analysis, 19 studies published between 1985 and 2023 met all the eligibility criteria and were included. A total of 7 studies presented as good and 12 studies presented as satisfactory. Patients were screened in ten studies and diagnostic records from archives were retrieved in nine studies. The total number of diagnostic records screened was 138.394, and the total number of patients from the included studies was 43.127. CONCLUSIONS Based on the findings from this systematic review, the prevalence of mandibular canine impaction ranged from 0.008% to 1.29% while canine transmigration from 0.12% to 0.98%. Crowding of the mandibular arch, the presence of a retained deciduous canine, and odontoma or cyst are the etiological factors more commonly associated with mandibular canine impaction and or transmigration. Surgical extraction and surgical exposure followed by orthodontic traction are the two most frequently carried out treatment modalities in the management of mandibular canine impaction and or transmigration.

Abstract
Epileptic spasms (ES) occur mostly between age 3 months and 24 months. ES beginning before 3 months of age were called early-onset ES in previous studies. The aim of this study was to identify clinical and electroencephalographic characteristics of patients with ES onset before 3 months of age. In total, 34 ES patients were retrospectively identified at Children's Hospital of Chongqing Medical University from January 1, 2020 to October 1, 2022. Our patients had diverse etiologies, including genetic (32.3 %), genetic-structural (11.8 %), structural-acquired (11.8 %), structural-congenital (8.8 %), and metabolic (5.9 %), with 29.4 % of patients having unknown etiology. Some patients experienced ES in clusters (either symmetrical or flexional) that occurred most often during awakening after sleep, and a minority of ES were characterized as isolated or asymmetrical, occurred during sleep, and could also manifest as relatively subtle. Approximately 35.3 % of patients also experienced other seizure types concurrently, including 10 focal seizures and 2 generalized seizures, and only half of the focal seizures had structural causes. The other seizure types occurred alone or sequentially with ES. Interictal electroencephalography revealed hypsarrhythmia or its variants, multifocal discharge, or burst suppression. 18 patients had no seizures lasting for more than 2 months, however, at the last follow-up visit, 5 of them had relapsed. All patients had different degrees of psychomotor retardation.

Abstract
PURPOSE This study aimed to give a full spectrum of orthopedic injuries associated with electric scooter (e-scooter) use and analyze related factors, report on follow-up data from the patient's perspective and make a comparative etiological analysis of young adult hip fractures. METHODS A total of 851 consecutive patients were admitted to the Emergency Department following e-scooter injuries between January 2021 and July 2022, of whom 188 had 214 orthopedic injuries. The demographics, injury, and incident characteristics of these patients were collected. All fractures were classified as per the AO/OTA classification. Two groups were created as operatively or conservatively treated patients and data were comparatively analyzed. Follow-up examination incorporated a survey using binary questions on patients' perspectives. An etiological comparative analysis of hip fractures in young adults admitted to the same center between 2016 and 2022 was conducted. RESULTS The median patient age was 25. Inexperienced drivers constituted 32% of the injured. The protective gear use rate was at 3%. Higher speed (p = 0.014) and age (p = 0.011) were significantly associated with operative treatment. A total of 39% of the operated patients could not return to preinjury physical function, while 74% regretted using an e-scooter. The most common etiological factor for traumatic young hip fractures was fall from a height between 2016 and 2020, whereas it became e-scooter accidents in 2021-2022. CONCLUSION The rate of e-scooter-related operative treatment is high and leaves the patient in regret (84%) and a physically limited condition (39%). A speed limit of ≤ 15 km/h could decrease the rate of operative injuries. The e-scooter was identified as the top etiological factor in the last 2 years for traumatic young hip fractures.

Abstract
The etiology of Major Depressive Disorder (MDD) has been associated with levels of trace elements in the human body. The source of trace elements in the human body may be rare earth elements (REEs). Our study aimed to identify the potential relationship between t REEs in blood and brain samples and depression from two paths: animal experiments and population studies. In the animal experiments, 35 adult Sprague-Dawley rats were randomly allocated to the control group (n = 14) and treatment group (n = 21), which received the chronic unpredictable mild stress (CUMS) procedure for four weeks and further categorized into the sensitive group (n = 9) and resilient group (n = 12) by sucrose water preference test. Then, all rats were executed to obtain serum and brain tissue samples. We also recruited 197 participants and divided them into the major depressive disorder (MDD) group (n = 100) and the control group (n = 97) then serum samples were collected for REEs detection. Our finding reported that significant differences were found in the levels of La and Ce in blood samples from different groups in the CUMS rat model (sensitive group < resilient group < control group) (all p < 0.05), with similar patterns for other elements (Pr, Nd, and Y) (but p > 0.5). No significant inter-group difference was reported in rat brain tissue samples. After adjusting for demographic variables, we found that the concentrations of all five REEs (La, Ce, Pr, Nd, Y) were lower in depression group than in control group (all p < 0.01). The current conjoint animal and human data supported appropriate levels of REEs have a certain protective effect on body health. These results may be attributed to Hormesis effects. Whether the possible favorable effects of REEs on improving symptoms of depression or can be applied to drug development remains to be further investigated.

Abstract
BACKGROUND Benign paroxysmal positional vertigo (BPPV) is the most prevalent form of peripheral vertigo, with vascular lesions being one of its suspected causes. The older adults are particularly vulnerable to BPPV. Cerebral small vessel disease (CSVD), on the other hand, is a clinical condition that results from damage of cerebral small vessels. Vascular involvement resulting from age-related risk factors and proinflammatory state may act as the underlying factor linking both BPPV and CSVD. AIM The objective of this study is to explore the potential correlation between BPPV and CSVD by examining whether individuals aged 50 and older with BPPV exhibit a greater burden of CSVD. MATERIALS AND METHODS This retrospective study included patients aged 50 years and older who had been diagnosed with BPPV. A control group consisting of patients diagnosed with idiopathic facial neuritis (IFN) during the same time period was also included. The burden of cerebral white matter hyperintensities (WMHs) was evaluated using the Fazekas scale. An ordinal regression analysis was conducted to investigate the potential correlation between BPPV and WMHs. RESULTS The study included a total of 101 patients diagnosed with BPPV and 116 patients with IFN. Patients with BPPV were found to be significantly more likely (OR = 2.37, 95% CI 1.40-4.03, p = 0.001) to have a higher Fazekas score compared to the control group. Brain infarctions, hypertension, and age were all identified as significant predictors of white matter hyperplasia on MRI, with OR of 9.9 (95% CI 4.21-24.84, P<0.001), 2.86 (95% CI 1.67-5.0, P<0.001), and 1.18 (95% CI 1.13-1.22, P<0.001) respectively. CONCLUSION Our findings suggest that vascular impairment caused by age-related risk factors and proinflammatory status may be contributing factors to the development of BPPV in individuals aged 50 and above, as we observed a correlation between the suffering of BPPV and the severity of WMHs.

Abstract
Fusarium wilt of banana, caused by Fusarium oxysporum f. sp. cubense (Foc), is a serious disease that threatens banana production worldwide. It is a long-standing problem in Hawaii, but there was little knowledge of the causal pathogen. We isolated a strain of Foc, named Foc-UH, from a field experiencing the disease epidemic in Hawaii. Infection assays of a diverse panel of 26 banana clones, including varieties used for differentiating pathogen races and fruit production, revealed Foc-UH has a race 1 pathogenic phenotype with an intermediate race 2 virulence, and revealed the differential resistance of varieties to infection. Separate phylogenetic analyses using the barcoding regions of three nuclear genes, seven complete nuclear genes, and single nucleotide polymorphisms within conserved whole genome protein coding sequences, placed Foc-UH into recently proposed taxonomic frameworks relevant to Foc and the Fusarium oxysporum species complex. Screening of the 99.7% complete draft genome identified five secreted in xylem (SIX) gene homologs, including SIX1d, SIX1f, SIX9a, SIX9b, and SIX13a. This profile is similar to that of several race 1 isolates except the absence of SIX4 and SIX6. Foc-UH was morphologically dissimilar to the nearest related isolates. Altogether, this study identified a unique isolate that causes banana Fusarium wilt, which represents the first characterization of the causal pathogen in Hawaii. The findings and the genomic resources generated in this study are expected to guide banana breeding and cultivar deployment in Hawaii and beyond, and contribute to further understanding of the pathogenicity and evolutionary systematics of Foc.

Abstract
Objectives This study aimed to identify the incidence of sudden cardiac death (SCD0 in adult patients under the age of 49 years, including adolescents with an out-of-hospital cardiac arrest that presented to the emergency department of a tertiary care hospital. Methods This retrospective cross-sectional study was conducted at the Royal Hospital, Muscat, Oman, between January 2015 and December 2019. All patients with out-of-hospital cardiac arrest were enrolled. The incidence of SCD was evaluated. Information about the patient's demographic data, the site of cardiac arrest, the mode of arrival, the duration of pre-arrest symptoms and if cardiopulmonary resuscitation was performed was gathered. Survival data at 3-year follow-up was obtained. Results A total of 117 out of 769 (15%) patients met the criteria for SCD. Male gender was predominant, with a median age of 33 years. In about 79.5% of the patients, cardiac arrest was witnessed. Only 43 patients (36.8%) received cardiopulmonary resuscitation at the arrest site; 21 patients (17.9%) had a shockable rhythm and 96 patients (82.1%) had a non-shockable rhythm. Spontaneous circulation was returned in 15 patients (12.8%). Nine patients (7.7%) were discharged from the hospital and 8 (6.8%) survived at least 36 months. Conclusion The study findings indicate the prevalence of SCD among patients who experienced a cardiac arrest outside the hospital. Unfortunately, only a small number of patients were able to survive in the long term. By implementing preemptive screening for individuals and their families, it may be possible to prevent SCD and improve outcomes for those affected.

Abstract
BACKGROUND Childhood and adolescent trauma is a risk factor for developing psychosis-spectrum disorders. The current study aimed to assess how childhood trauma might predict psychosis symptomatology, and how patients' beliefs of whether trauma is the cause of psychosis might affect this association. METHODS Ninety-six first-episode psychosis patients were assessed for childhood traumatic experiences with the Brief Betrayal Trauma Survey, and for psychosis symptoms with the Positive and Negative Syndrome Scale. RESULTS Non-interpersonal trauma predicted higher positive symptoms, whereas more trauma domains experienced predicted lower negative symptoms. Almost half of the participants believed trauma to be related to psychosis, were 12 times more likely to reexperience trauma through psychosis, and had higher excitative and emotional symptoms. Non-interpersonal trauma also predicted higher positive symptoms in this group. Those who did not believe trauma to be the cause of psychosis had higher negative symptoms, and a negative dose-response was found for negative and disorganised symptoms, in which more trauma domains experienced predicted lower scores. CONCLUSIONS Results imply two traumagenic pathways to psychosis, one characterised by positive, excitative, and emotional symptoms, and one negative subtype, characterised by negative and disorganised symptoms. Clinical implications for how findings might contribute to better treatments are discussed.

Abstract
Scleritis and episcleritis are rare ocular inflammatory diseases but deserve to be known by internists because of their frequent association with systemic autoimmune diseases. It is important to distinguish them between because their prognosis, therapeutic management and potential complications are very different. Episcleritis represents a superficial ocular inflammation with usually benign visual prognosis, no complication with local treatment, and is associated with a systemic autoimmune disease in rare cases. In contrast, scleritis is a potentially serious ophthalmological condition that can threaten the visual prognosis in the absence of appropriate systemic treatment. It is associated with an underlying disease in 40-50% of cases, in particular a systemic autoimmune disease (25-35% of cases) or an infectious cause (5-10% of cases). Rheumatoid arthritis and systemic vasculitides, particularly antineutrophil cytoplasmic antibody (ANCA)-associated vasculitides, are the main autoimmune causes of scleritis and episcleritis. Scleritis can reveal the underlying autoimmune disease and requires systematic etiological investigations. Aggressive, complicated, refractory forms or those associated with a systemic autoimmune disease require glucocorticoids or even immunosuppressants, and close collaboration between ophthalmologists and internists is required. The development of biologic agents offers new effective therapeutic tools in the management of these difficult cases.

Abstract
BACKGROUND This study aimed to investigate and analyze the risk factors for non-etiology-specific infantile spasms (IS) and unrelieved clinical symptoms after treatment. METHODS Eighty-eight children with IS who were treated at our hospital from March 2018 to December 2021 were included in the study. The children were divided into etiology-specific (n = 46) and nonetiology-specific (n = 42) groups, based on the diagnostic results, and remission (n = 45) and nonremission (n = 43) groups, based on clinical outcomes after treatment. The clinical data from patients in the etiology-specific and nonetiology-specific groups and the remission and nonremission groups were compared. Risk factors for non-etiology-specific IS were identified using logistic regression analysis. RESULTS Gender, family history, birth status, and metabolic abnormalities were significantly different between the etiology-specific and non-etiology-specific groups. Gender and metabolic abnormalities were risk factors for nonetiology-specific IS. Family history, birth status, metabolic abnormalities, and brain magnetic resonance imaging were significantly different between the remission and nonremission groups, and different etiologies were risk factors for unrelieved symptoms after treatment. CONCLUSION The occurrence of nonetiology-specific IS is associated with gender and metabolic abnormalities in children. After medication, unrelieved IS symptoms are associated with etiologies.

Abstract
Nowadays, diabetes mellitus has emerged as a significant global public health concern with a remarkable increase in its prevalence. This review article focuses on the definition of diabetes mellitus and its classification into different types, including type 1 diabetes (idiopathic and fulminant), type 2 diabetes, gestational diabetes, hybrid forms, slowly evolving immune-mediated diabetes, ketosis-prone type 2 diabetes, and other special types. Diagnostic criteria for diabetes mellitus are also discussed. The role of inflammation in both type 1 and type 2 diabetes is explored, along with the mediators and potential anti-inflammatory treatments. Furthermore, the involvement of various organs in diabetes mellitus is highlighted, such as the role of adipose tissue and obesity, gut microbiota, and pancreatic β-cells. The manifestation of pancreatic Langerhans β-cell islet inflammation, oxidative stress, and impaired insulin production and secretion are addressed. Additionally, the impact of diabetes mellitus on liver cirrhosis, acute kidney injury, immune system complications, and other diabetic complications like retinopathy and neuropathy is examined. Therefore, further research is required to enhance diagnosis, prevent chronic complications, and identify potential therapeutic targets for the management of diabetes mellitus and its associated dysfunctions.

Abstract
BACKGROUND Tumor-induced osteomalacia (TIO) belongs to a rare disease of the paraneoplastic syndrome. Phosphate uric mesenchymal tumor (PMT) is the most common cause of TIO, while the possibility of other tumors cannot be excluded. CASE PRESENTATION We present a case of a 36-year-old female patient with systemic skeletal abnormalities. The woman complained of low back pain with mild motor dysfunction for 2 years. Laboratory examination showed abnormalities in markers of bone metabolism, parathyroid hormone (PTH), vitamin D and serum phosphorus. Pooled imaging examination indicated extension abnormalities in the skeletal system and a single lesion in the right femoral head. The lesion of the right femoral was imaging with somatostatin receptor-positive, which was highly suggestive of a single neuroendocrine tumor. CT guided right femoral tumorectomy and bone grafting were performed when medical treatment failed. Postoperative pathological diagnosis was phosphate urinary mesenchymal tumor secreting fibroblast growth factor 23 (FGF23), which accorded with pre-operative expectations. The postoperative symptoms were effectively relieved, and indicators returned to normal. CONCLUSION The tumors causing TIO exhibited significant heterogeneity in terms of tissue origin, pathological characteristics and biological behavior, but the unique common characteristic is the secretion of FGF23. With significant progress in diagnosis and treatment, the clinical follow-up of most TIO patients shows a good prognosis, but the prognosis of those with malignant tumors is relatively poor.

Abstract
BACKGROUND Hypertriglyceridemia (HTG) is frequently observed in non-HTG-induced acute pancreatitis (AP), such as in the early stage of acute biliary pancreatitis (ABP). There is overlap in the etiologies of ABP, HTG-AP, and biliary-hypertriglyceridemia acute pancreatitis (BHAP), which may be perplexing for clinicians. METHODS We retrospectively analyzed 394 AP patients. The patients were divided into three groups based on etiology. We analyzed the differences among the three groups of patients in terms of general information, laboratory parameters, and prognosis. RESULTS The mean age of patients in the ABP group was significantly higher than that in the HTG-AP and BHAP groups (p < 0.001). Females made up a greater percentage of the ABP group, whereas males made up the majority in the HTG-AP and BHAP groups. The ABP group had the highest PCT, AMS, LPS, ALT, AST, GGT, TBIL, DBIL, APACHE II, and BISAP scores. TG and BMI were highest in the HTG-AP group. AST and GGT levels were substantially greater in BHAP patients than those in HTG-AP. The BHAP group had the greatest incidence of organ failure, systemic complications, and local complications. CONCLUSION ABP usually develops in people aged 50-59 years. HTG-AP primarily affects people aged 30-39 years. However, the peak incidence age of BHAP falls between the two aforementioned age groups (40-49 years). We also found that patients with BHAP seem to be in an intermediate state in terms of some biochemical markers and demographic characteristics. Furthermore, BHAP may have the worst clinical outcomes compared with HTG-AP and ABP.

Abstract
Pitaya, Hylocereus costaricensis, is a species of the Cactaceae family and originated in the Americas (Ortiz & Livera, 1995). It has been cultivated in Brazil and has shown a great potential for fruit production and is currently present in several markets (Faleiro et al. 2021). In July 2018, infected plants of pitaya with symptoms of anthracnose were obtained from an orchard in Fortaleza, Ceará Brazil, (3°44'24.5"S 38°34'30.8"W), with 50% disease incidence. The symptoms observed consisted of well-defined and depressed stains, that initially appeared as reddish-orange spots and were surrounded by a border of dark-brown color. As the lesion progressed, the center became light brown or whitish in color, with black dots appearing later. Four cladodes were collected with anthracnose symptoms. The pathogen was isolated from symptomatic cladodes, which were surface disinfected with 1% v/v NaClO and 70% v/v ethanol, rinsed with sterile distilled water, transferred onto potato dextrose agar (PDA) medium and incubated under a light/dark (12h/12h) photoperiod. Two isolates were recovered from the lesions on cladodes. Pure cultures were obtained from single conidia produced on colonies grown on PDA medium, using an inoculation needle under a microscope. Colonies on PDA exhibited white aerial mycelia with an orange conidial mass. The colonies were light grey in the front and light orange in the reverse of the plate. Morphological features suggested that the isolates had the same characteristics as previously described for Colletotrichum spp. (Weir et al., 2012). In order to identify the species of the isolates, the genomic DNA of UFCM 0684 and UFCM 0685 isolates was extracted using the CTAB method and the ITS region, TUB2, ACT, GS, GAPDH gene fragments were amplified. PCR products were sequenced and the resulting sequences were submitted to phylogenetic analyses based on maximum likelihood for the combination of the genes. The isolates grouped within Colletotrichum tropicale with 99% bootstrap support. The sequences obtained in this study were deposited in GenBank as ACT (accession no. OL799311, OL799312), TUB2 (OL799313; OL799314), GAPDH (OL799315, OL799316), GS (OL799317; OL799318) and ITS (OL799319; OL799320). After that, the UFCM 0685 isolate was selected to study for further characterization. Conidia (n = 50) were 13.7 (length) × 4.7 μm (width) in average, hyaline, aseptate and cylindrical. To complete Koch's postulates, pathogenicity tests were performed in moist chamber for one week at 25°C with 80% relative humidity on a 12 h fluorescent light/dark photoperiod. The cladodes were wounded using a sterilized needle and inoculated with 10 µl of a conidial suspension (1 × 106 conidia/ml) on three cladodes with five wounds each. The same number of uninoculated cladode was used as control. The experiment was performed twice. Two weeks later, all inoculated cladodes showed necrotic symptoms, which were similar to the symptoms previously observed in the field. The uninoculated cladode remained symptomless. The fungus was reisolated from the inoculated cladode and its morphological characteristics were similar to the original isolate. Colletotrichum tropicale has been reported to cause anthracnose on H. costaricensis in Mexico (Nunez-Garcia et al. 2023), H. undatus, H. monocanthus and H. megalanthus (Evallo et al. 2022). For the best of our knowledge, this is the first report of anthracnose caused by C. tropicale in H. costaricensis in Brazil.

Abstract
Peanut (Arachis hypogaea) is an important economic and oil crop in China. In September 2022, leaf spots were observed on peanut in Luoyang city, Henan province, China (34°49'N, 112°37'E). The disease occurred on about 30% of the peanut leaves in only one 0.5-acre field. Symptoms appeared primarily as brown spots, that varied in shape, and appeared round, oval or irregular. In addition, some disease patches exhibited a concentric ring pattern. Small pieces (5×5 mm) of five diseased leaves were surface disinfected in 3% NaClO for 2 minutes, rinsed three times in sterile distilled water, dried on sterilized filter paper, and cultured on potato dextrose agar (PDA) at 25°C for 3 days. Five isolates with uniform characteristics were obtained and subcultured by transferring hyphal tips to fresh PDA. The colonies of the isolates were circular and the margins were clean. The colonies showed white coloration, and after 5-7 days of incubation on PDA plates, concentric rings with dark green sporodochia appeared on the surface of the colonies. The conidiophores branched repeatedly. The conidiophore stipes unbranched, hyaline, 10.0 to 23.2×1.5 to 3.3 μm (n=50). The conidia were rod-shaped or long oval and single-celled, measuring 4.6 to 8.6×1.4 to 3.1 μm (n=100). Based on these characteristics, the five isolates were identified as Paramyrothecium foliicola (Lombard et al 2016). Genomic DNA was extracted from the representative isolates LH-1-1 and LH-1-2. The internal transcribed spacer (ITS), RNA polymerase II second largest subunit (RPB2), calmodulin (CmdA), and translation elongation factor 1-alpha (tef1) loci were amplified and sequenced using the following primer pairs: ITS1/ITS4 (White et al. 1990), RPB2-5F2/RPB2-7cR (O'Donnell et al. 2007), CAL-228F/CAL-2Rd (Carbone & Kohn 1999), and EF1-728F/EF2 (O'Donnell et al. 1998), respectively. BLASTn analysis revealed that the sequences of ITS (OR352397.1 and OR417392.1), RPB2 (OR413573.1 and OR420678.1), CmdA (OR413572.1 and OR420677.1), and tef1 (OR413574.1 and OR420679.1) had 99 to 100% (553/558 bp, 721/721 bp, 597/598 bp, and 384/389 bp) similarity to P. foliicola (MN593634.1, MN398038.1, OM801785.1, MK335967.1). A phylogenetic tree based on the Maximum Likelihood method also confirmed that the two isolates converge on the same branch as P. foliicola. Pathogenicity tests were performed using leaves of 60-day-old peanut plants (cv. Zhonghua 8). Briefly, uninfected healthy leaves (non-wounded) were inoculated with 30-µl drops containing a spore suspension (5×105 conidia/ml) of LH-1-2, and peanut leaves inoculated with sterile distilled water served as controls. All treatments were incubated in an incubator at 25℃ and high relative humidity with a 12:12 hour light-dark cycle. After 5-7 days, inoculated leaves showed symptoms similar to those observed in the field, while no symptoms were observed on control leaves. The pathogenicity tests were repeated three times. The fungus was reisolated from the infected leaves and identified as P. foliicola based on morphological and molecular characteristics, thus fulfilling Koch's postulates. P. foliicola has previously been reported to cause leaf spot of tomato and mung bean, stem canker of cucumber (Huo et al. 2022; Sun et al.2020; Huo et al. 2021). To our knowledge, this is the first report of P. foliicola causing leaf spot on peanut in the world. Identification of this pathogen will be helpful in monitoring peanut diseases and developing disease control strategies.

Abstract
BACKGROUND Hepatitis E can potentially progress to HEV-related acute liver failure (HEV-ALF). East and South Asia bear a substantial burden of HEV infection, with Bangladesh, China, and India facing the most severe threat in this region. Therefore, we conducted a systematic review and meta-analysis to evaluate the burden of HEV-ALF in these three high-risk countries. METHODS A systematic literature search was performed utilizing PubMed, the Cochrane Library, Medline, Embase, and Web of Science databases. Studies in English or Chinese that reported data on the burden of HEV-ALF in Bangladesh, China and India were included. Outcomes were pooled with meta-analysis utilizing R software. Estimates were calculated with random-effects models, and subgroup analysis and sensitivity analysis were conducted to address heterogeneity. Egger's test and Begg's test were performed to assess publication bias. RESULTS A total of 20 eligible studies were included in this study. The pooled HEV-attributable proportion of viral-related acute liver failure was estimated to be 40.0% (95% CI: 0.28-0.52), 30.0% (95% CI: 0.18-0.44), and 61.0% (95% CI: 0.49-0.72) among non-pregnant individuals in India, China and Bangladesh, while in Indian pregnant females, it was 71.0% (95% CI: 0.62-0.79). The combined prevalence among non-pregnant HEV-infected participants was 28.0% (95% CI: 0.20-0.37) and 10.0% (95% CI: 0.01-0.28) in India and China, and it was 34.0% (95% CI: 0.27-0.42) in Indian pregnant females with HEV infection. The overall mortality of HEV-ALF was estimated to be 32.0% (95% CI: 0.23-0.42) and 64.0% (95% CI: 0.50-0.77) among the non-pregnant and the pregnant participants in India, and it was 23.0% (95% CI: 0.14-0.34) in Chinese non-pregnant participants. CONCLUSIONS The burden of HEV-ALF in Bangladesh, China, and India is non-negligible despite geographic and population heterogeneity. The prevention of HEV infection and early recognition of HEV-ALF are of great significance, especially in high-risk countries and populations. REGISTRATION PROSPERO registration ID is CRD42022382101.

Abstract
Chronic liver disease (CLD) imposes a heavy burden on millions of people worldwide. Despite substantial research on the pathogenesis of CLD disorders, no optimal treatment is currently available for some diseases, such as liver cancer. Exosomes, which are extracellular vesicles, are composed of various cellular components. Exosomes have unique functions in maintaining cellular homeostasis and regulating cell communication, which are associated with the occurrence of disease. Furthermore, they have application potential in diagnosis and treatment by carrying diverse curative payloads. Hepatic macrophages, which are key innate immune cells, show extraordinary heterogeneity and polarization. Hence, macrophage-derived exosomes may play a pivotal role in the initiation and progression of various liver diseases. This review focuses on the effects of macrophage-derived exosomes on liver disease etiology and their therapeutic potential, which will provide new insights into alleviating the global pressure of CLD.

Abstract
BACKGROUND Given the physiological changes during pregnancy, pregnant women are likely to develop recurrent urinary tract infections (UTIs) and pyelonephritis, which may result in adverse obstetric outcomes, including prematurity and low birth weight preeclampsia. However, data on UTI prevalence and bacterial profile in Latin American pregnant women remain scarce, necessitating the present systematic review to address this issue. METHODS To identify eligible observational studies published up to September 2022, keywords were systematically searched in Medline/PubMed, Cochrane Library, Embase, Web of Science, and Bireme/Lilacs electronic databases and Google Scholar. The systematic review with meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the quality of studies was classified according to the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. The meta-analysis employed a random-effects method with double-arcsine transformation in the R software. RESULTS Database and manual searches identified 253,550 citations published until September 2022. Among the identified citations, 67 met the inclusion criteria and were included in the systematic review, corresponding to a sample of 111,249 pregnant women from nine Latin American countries. Among Latin American pregnant women, the prevalence rates of asymptomatic bacteriuria, lower UTI, and pyelonephritis were estimated at 18.45% (95% confidence interval [CI]: 15.45-21.53), 7.54% (95% CI: 4.76-10.87), and 2.34% (95% CI: 0.68-4.85), respectively. Some regional differences were also detected. Among the included studies, Escherichia coli (70%) was identified as the most frequently isolated bacterial species, followed by Klebsiella sp. (6.8%). CONCLUSION Pregnant women in Latin America exhibit a higher prevalence of bacteriuria, UTI, and pyelonephritis than pregnant women globally. This scenario reinforces the importance of universal screening with urine culture during early prenatal care to ensure improved outcomes. Future investigations should assess the microbial susceptibility profiles of uropathogens isolated from pregnant women in Latin America. TRIAL REGISTRATION This research was registered at PROSPERO (No. CRD42020212601).

Abstract
BACKGROUND Carotid web (CaW) and carotid free-floating thrombus (CFFT) are rare yet critical causes of ischemic stroke in young adults. CASE PRESENTATION A 54-year-old woman presented with a fluctuating right sensory-motor faciobrachial syndrome. A brain MRI scan revealed multiple small recent asynchronous cortico-subcortical ischemic foci in the vascular territory of the left internal carotid artery. A CT angiography identified a CFFT in the left internal carotid artery arising from an underlying CaW. The patient was treated with excellent clinical outcomes with carotid artery stenting and dual antiplatelet therapy. CONCLUSIONS We provide a structured pathophysiological rationale connecting CaW and CFFT and highlight pivotal therapeutic implications. Further studies are needed to investigate this relationship and guide assessment and treatment.

Abstract
California is the sixth largest apple-producing state in the United States with a production that reached 4,654 ha in 2021. During the late winter of 2023, black canker symptoms were observed on branches of 'Gravenstein' apple (Malus domestica) in two commercial orchards in Sonoma County, California. The prevalence of symptomatic trees ranged from 10 to 30%. External symptoms included charcoal looking-cankers with the bark peeling off from the primary and secondary branches. Internally, cankers were dark brown in color with a hard consistency. Pycnidia were observed on the surface of older cankers. Fungal isolations were performed from disinfected (70% ethanol, 30 s) symptomatic branch samples (n = 15). Small wood pieces (5 mm length) were taken from the margin of diseased and healthy tissues, and placed on potato dextrose agar acidified with 92% lactic acid at 0.5 mL per liter (APDA). Plates were incubated at room temperature (20-22 °C) for 7 days. Colonies of Botryosphaeriaceae species (Phillips et al. 2013) (n = 12) were consistently recovered and pure cultures were obtained by transferring a single hyphal tip onto fresh APDA. Colonies were light gray with irregular margins. To induce pycnidia formation, two isolates (UCD11350 and UCD11351) were grown on pistachio leaf agar for 21 days. Conidia (n = 50) were thick-walled and ovoid in shape, initially hyaline, then turned pale brown and dark brown at maturity, and some of them became 1-septate, ranging from 18.9 to 24.0 (21.9) × 11.5 to 14.7 (13.4) µm. Isolates were identified by sequencing a partial region of the beta-tubulin (tub2) gene using the primers Bt2a/Bt2b (Glass and Donaldson 1995). BLAST searches on NCBI GenBank revealed 99.5 % identity with the Diplodia bulgarica ex-type (CBS 1245254). To confirm the identity, the rRNA internal transcribed spacer (ITS) and the translation elongation factor 1-alpha (tef1) were also sequenced using ITS5/ITS4 (White et al. 1990), and EF1-688F/EF1-1251R (Alves et al. 2008), respectively. A maximum parsimony multi-locus phylogenetic analysis clustered Californian isolates with reference strains of D. bulgarica. Sequences were deposited in GenBank (nos. OR631209 to OR631210, OR637361 to OR637362, OR637363 to OR637364 for ITS, tub2, and tef1, respectively). Pathogenicity tests were conducted on 2 to 3-year-old branches (n = 5) of over 20-year-old trees by inserting a 5-mm segment of a toothpick, completely colonized with each of the two isolates mentioned above, into a 1-mm-diameter hole made with a sterile drill bit. The same number of branches where mock inoculated with a non-colonized toothpick as negative control. The experiment was performed twice. After ten weeks, inoculations resulted in dark brown necrotic lesions that ranged from 54.0 to 59.8 mm in length. Negative controls remained asymptomatic. Koch's postulates were fulfilled by successfully recovering the isolates from the lesion margins, which were confirmed by morphology. Diplodia bulgarica was first described affecting M. sylvestris in Bulgaria (Phillips et al. 2012), and then detected on M. domestica causing cankers in Iran (Abdollahzadeh 2015), India (Nabi et al. 2020), Germany (Hinrichs-Berger al. 2021) and Türkiye (Eken 2021). The pathogen was also identified causing postharvest fruit rot (Eken 2022). To our knowledge, this is the first report of D. bulgarica causing branch canker on apple in California, which provides important information for developing detection and control strategies.

Abstract
The European hazelnut (Corylus avellana) is an important fruit crop cultivated in Chile, with over 17,000 ha planted (46%) in the Maule region, central Chile. During a routine orchard survey in seasons 2020-2021 and 2021-2022, in the Maule region, canker and dieback symptoms were observed in two commercial orchards of European hazelnut cv. Tonda Di Giffoni in San Rafael (8-year-olds) and Linares (15-year-olds), with an incidence between 10% and 36%, respectively, based on external symptoms. Twenty symptomatic branches exhibiting cankers, reduced vigor, wilting, twig death, and dieback, were collected. A cross-section of diseased branches revealed mostly brown V or U-shaped cankers of hard consistency. Branches were cut, and pieces of cankers were surface sterilized in 96% ethanol for 3 s and briefly flamed. Small pieces of wood (5 mm2) from the edge of cankered tissues were placed on Potato Dextrose Agar (2% PDA) amended with 0.1% Igepal CO-630 and incubated at 25°C for five days in the dark (Díaz and Latorre 2014). Pure cultures were obtained by transferring a hyphal tip from growing colonies to fresh PDA media. Eight pure cultures (NP-Haz01 to NP-Haz08) developed dark to olive-brown fast-growing colonies with scarce aerial mycelium after seven days at 25°C on PDA under near-UV light. These isolates showed a dark-olive color on the reverse side of Petri dishes and developed abundant, aggregated, and dark-brown globose pycnidia after 21 days at 25°C. Conidia were hyaline, aseptate, ellipsoidal, densely granulate, externally smooth, and thin-walled dark, that measured (9.5-) 15.5 ±1.2 (-17.3) x (5.1-) 7.2 ± 0.6 (-9.1) µm (n = 30), with a length/width ratio of 2.15. These isolates were tentatively identified morphologically as Neofusicoccum sp. Molecular identification was performed using ITS1/ITS4, Bt2a/Bt2b and EF1-728F/EF1-986R primers of the internal transcribed spacer (ITS1-5.8S-ITS2) region, a portion of the beta-tubulin (BT) and part of the translation elongation factor (EF1-) genes, respectively (Dissanayake et al. 2015). A MegaBlast search in GenBank showed a 99% similarity to isolate CMW9081, the ex-type of Neofusicocum parvum (Pennycook & Samuels) Crous, Slippers & A.J.L. Phillips. The sequences were added to GenBank (OR393855 to OR393857 for ITS; OR400688 to OR400690 for BT; OR400691 to OR400693 for EF1-). Pathogenicity of three isolates (NP-Haz02, NP-Haz04, NP-Haz09) was studied on freshly made pruning wounds on attached branches of 3-year-old and one-year-old of European hazelnut cv. Tonda Di Giffoni in the San Rafael field. Fifteen pruning wounds were inoculated with 40 µL conidial suspension (105 conidia/mL) of each isolate of N. parvum. Sterile distilled water was used as a control treatment (n=15 branches) for branches of 3-year-olds and one-year-olds. Both pathogenicity tests were repeated once. Attached branches of 3-year-olds (6 months of incubation) and one-year-olds (4 months of incubation), developed necrotic streaks and cankers with a mean length of 33 to 82 mm and 25 to 51 mm, respectively. No necrotic streaks were observed in the branches treated with water. Neofusicoccum parvum was reisolated only from symptomatic tissues of inoculated branches, and morphological and molecularly (EF1-) identified, thus fulfilling Koch's postulates. Previously, other Botryosphaeriaceae spp. as Diplodia coryli (Guerrero and Pérez 2012) and D. mutila (Moya-Elizondo et al. 2023) have been obtained from canker and dieback of hazelnut in Chile. Recently, N. parvum was reported causing nut rot in hazelnuts in Italy (Wagas et al. 2022). To our knowledge, this is the first report of N. parvum causing canker and branch dieback of hazelnut trees in Chile and worldwide.

Abstract
BACKGROUND There have been many epidemiologic studies on community-acquired pneumonia (CAP) among children, most of which had substantial limitations. This study investigated the etiologic distribution and clinical characteristics of CAP in Korean children for 5 years before the coronavirus disease 2019 (COVID-19) pandemic. METHODS A retrospective analysis of children hospitalized for CAP at 4 referral hospitals during 2015-2020 was performed. Cases in which bronchiolitis was suspected or pulmonary infiltration was not evident on chest radiography (CXR) were excluded. Viruses and atypical bacteria were defined as detected when positive in the polymerase chain reaction test performed for respiratory specimens. Serologic testing result for Mycoplasma pneumoniae was incorporated with strict interpretation. Pyogenic bacteria were included only when cultured in blood, pleural fluid, or bronchoalveolar lavage, but those cultured in endotracheal aspirate or sputum when the case was clinically evident bacterial pneumonia were also included. RESULTS A total of 2,864 cases of suspected pneumonia were selected by diagnosis code and CXR findings. Medical chart and CXR review excluded nosocomial pneumonia and cases without evident infiltration, resulting in 517 (18.1%) CAP cases among 489 children. Regarding clinical symptoms, high fever was present in 59.4% and dyspnea in 19.9% of cases. Respiratory support was required for 29.2% of patients, including mechanical ventilation for 3.9%. Pathogens were detected in 49.9% of cases, with viruses in 32.3%, atypical bacteria in 17.8%, and pyogenic bacteria in 2.3% of cases. As single pathogens, M. pneumoniae (16.8%) and respiratory syncytial virus (RSV, 13.7%) were the most common. Parenteral β-lactam and macrolide antibiotics were administered in 81.6% and 50.7% of cases, respectively. A total of 12 (2.3%) cases resulted in poor outcomes, including 3 deaths. CONCLUSION M. pneumoniae and RSV were the most commonly detected pathogens of pediatric CAP, which was selected by strict clinical and radiologic criteria. It is necessary to carefully decide whether to use parenteral antibiotics based on the epidemiology and clinical features of CAP in children.

Abstract
China ranks first in the production and harvest area of walnut (Juglans regia L.) worldwide. Currently, the poor health and low yield of walnut caused by pathogen infection is of concern. In 2022, severe walnut leaf spot disease was observed on the seedlings of four walnut nurseries (0.08 to 0.23 ha) in Liaocheng, Shandong, China, with an average incidence of 48.6% (from 34.6% to 65.3% on the cultivar Xiangling). From August to October, leaf spots mainly appeared on the edges of the leaflets, and occasionally between veins. The lesions were initially soft and rotten, and then light brown, round to semi-circular. Subsequently, the adjacent lesions fused, and the edges of the leaflets and entire leaflets showed symptoms of browning and wilting. For pathogen isolation, five leaflets with representative symptoms from one of the nurseries were collected and wiped three times with sterile absorbent cotton dipped in 75% alcohol and washed with distilled water. Leaflet pieces at the junction of the lesion and healthy tissues were removed, crushed in a sterile mortar, and soaked in a small amount of distilled water for 10 min. The diseased tissue suspension was streaked on a nutrient agar medium (NA) with a sterile inoculation ring and incubated at 28°C for 24 to 72 h. The bacterial colonies obtained were further cultured on NA. The purified colonies were uniform in shape, round, and yellow, with a raised, shiny surface and smooth margin. The isolates were Gram-negative, and the electron microscope analysis showed that the pathogens were short rods (0.35 to 0.52 × 0.90 to 1.24 μm, average = 0.44 ± 0.05 × 1.08 ± 0.11 μm, n = 25). For bacterial species identification, a single-colony culture was subjected to genomic DNA extraction and gene amplification and sequencing of 16S rRNA, rpoD, and gyrB. The universal primers 27F/1492R (Lane 1991) were used to amplify the 16S rRNA gene and the specific primers 70F/70R and UP-1E/APrU (Yamamoto et al. 2000) were used to amplify the rpoD and gyrB genes, respectively. In the BLAST analysis, the 16S rRNA sequence (GenBank OR195734) of the isolate shared 99% similarity (1409/1410 bp) with Pseudomonas oryzihabitans strain IAM 1568T (AM262973.1), and the rpoD (OR709708) and gyrB (OR709707) sequences showed >98% identity to rpoD (707/717 bp; FN554494.1) and gyrB (787/801 bp; FN554210.1) of P. oryzihabitans strain LMG 7040T. Based on the above results, the isolated bacterium was identified as P. oryzihabitans. For the pathogenicity test, healthy leaflets from 10 two-year-old potted walnut seedlings (cv. Xiangling) were used as inoculation materials. The leaflets were punctured with a sterile inoculation needle of 0.4 mm, and three small holes on each leaflet at an interval of about 5 mm were covered with a piece of sterile cotton. A bacterial suspension (1 ml) at 107 CFU/ml was spread onto the cotton, and wrapped with plastic film for 24 h. Water was used as a negative control. The inoculations were performed five times. Plants were grown outdoors at a daily average temperature of 22°C with relative humidity over 45%. Two days after inoculation, the disease began to develop in the leaflets with similar symptoms to those observed in the field. In contrast, control plants remained healthy and symptomless. Bacteria were reisolated from the inoculated walnut plants, and the morphology and 16S rRNA gene sequences of the isolates were the same as those of the original strains. Since it was discovered as an opportunistic human pathogenic bacterium in the 1970s (Keikha et al. 2019), P. oryzihabitans has also been shown to cause certain plant diseases, such as panicle blight and grain discoloration on rice (Hou et al. 2020), fruit black rot on prickly ash (Liu et al. 2021), and stem and leaf rot on muskmelon (Li et al. 2021). As far as we know, this is the first report of P. oryzihabitans causing walnut leaf spot disease in China. Leaf spot caused by P. oryzihabitans may be a threat to walnut cultivation, and this report of its occurrence is the first step in determining potential spread and effective control measures.

Abstract
Regardless of etiology, hepatocarcinogenesis is frequently preceded by a distinctive sequence of chronic necroinflammation, compensatory hepatic regeneration, development of hepatic fibrosis, and ultimately cirrhosis. The liver being central immunomodulators, closely maintains immunotolerance. Any dysregulation in this management of immunotolerance is a hallmark of chronic hepatic disease and hepatocellular carcinoma (HCC). Apart from other malignancies, hepatocellular carcinoma accounts for 90% of liver cancers. Several emerging evidences have recognized diet as lifestyle associated risk factor in HCC development. However, natural compounds have the potential to fight hepatoma aggressiveness via inhibition of cellular proliferation and modulation of oncogenic pathways. This review aimed to identify the several plant-based foods for their protective role in HCC prevention by understating the molecular mechanisms involved in inhibition of progression and proliferation of cancer. Information from relevant publications in which several plant-based foods demonstrated protective potential against HCC has been integrated as well as evaluated. For data integration, Science direct, Google scholar, and Scopus websites were used. Nutrition-based approaches in the deterrence of several cancers offer a substantial benefit to currently used medical therapies and should be implemented more often as an adjunct to first-line medical therapy. Furthermore, the inclusion of these plant-based foods (vegetables, fruits, herbs, and spices) may improve general health and decline cancer incidence.

Abstract
PURPOSE No therapeutic intervention is universally accepted for frozen shoulder, and the most effective management to restore motion and diminish pain has yet to be defined. The aim of this study was to investigate functional and psychological outcomes in patients who underwent arthroscopic capsular release for a frozen shoulder. METHODS A retrospective study with prospective data collection was conducted with 78 patients suffering from frozen shoulder resistance to conservative treatment. Considering the etiology, there were 36 (46.2%) idiopathic, 31 (39.7%) postoperative, and 11 (14.1%) posttraumatic cases. Preoperatively, each patient was evaluated with the range of motion (ROM) assessment and the Constant-Murley score (CMS). At follow-up, the 4-point subjective satisfaction scale (SSS), the ROM assessment, the SF-12 questionnaire, the numerical rating scale (NRS) for the subjective assessment of pain, the CMS and the Hospital Anxiety and Depression Scale (HADS) were assessed. RESULTS After a mean follow-up of 54.2 ± 22.3 months, ROM and CMS showed a statistically significant improvement between pre- and postoperative values (all p < 0.001). Before surgery, the mean CMS was 36.9% that of sex- and age-matched healthy individuals, and all patients showed a CMS lower than the normative data. At the final follow-up visit, the mean CMS was 99.9% that of sex- and age-matched healthy individuals, and 49 (62.8%) patients showed a CMS equal to or higher than the normative data. The mean increase in the CMS was 56.1 ± 8.3 points. The mean SSS, HADS-A, HADS-D, and NRS were 3.7 ± 0.5, 2.5 ± 1.6, 2.2 ± 1.3, and 2.2 ± 1.0, respectively. All patients returned to their previous level of work and sports activity after 2 and 2.5 months, respectively. The multivariate analysis showed the association between a higher postoperative CMS and the idiopathic etiology of a frozen shoulder (p = 0.004, β = 3.971). No intraoperative complications occurred. Postoperatively, four patients (5.1%) were treated with intra-articular steroid injections to manage residual symptoms. One patient (1.3%) with a postoperative frozen shoulder showed persistent symptoms and underwent a new successful arthroscopic capsular release. CONCLUSION High patient satisfaction and statistically significant ROM and CMS recovery can be achieved after arthroscopic capsular release to manage frozen shoulder. Better functional outcomes are expected when the etiology is idiopathic. Results can help surgeons identify the patients who will most benefit from surgery and should be discussed with the patient. LEVEL OF EVIDENCE III.
