ABSTRACT

BACKGROUND: Predictors of permanent pacemaker implantation (PPMI) after self-expanding transcatheter aortic valve implant (TAVI) were described. Is unknown if PPMI predictors remain in the era of high implants using the cusp overlap (COP).

METHODS: Single-center, prospective, consecutive case series of patients undergoing self-expanding TAVI with the COP approach. The status of PPMI and other clinical events were ascertained at 30 days.

RESULTS: A total of 261 patients were included (84% with Evolut, n = 219). Implant depth >4 mm was infrequent (13.8%). TAVI depth (OR 1.259; p = 0.005), first or second-degree auriculo-ventricular block (OR 3.406; p = 0.033), right-bundle (OR 15.477; p < 0.0001), and incomplete left-bundle branch block (OR 7.964; p = 0.036) were found to be independent predictors of PPMI. The risk of PPMI with deep implant and no electrical disturbances was 3%, and 0% with high implant and no prior electrical disturbances. Those who received PPMI had no statistically significant increased risk of death, myocardial infarction, stroke, bleeding events, or vascular complications at 30 days, but longer hospital stay (mean difference 1.43 days more, p = 0.003).

CONCLUSIONS: Implant depth and prior conduction abnormalities remain the main predictors of PPMI using self-expanding TAVI in the COP era. Patients with high implants and no prior conduction abnormalities may be candidates for early discharge after uneventful self-expanding TAVI, while the rest may need inpatient monitoring regardless of achieving a high implant. The need for PPMI was associated with longer hospital stays.

ABSTRACT

BACKGROUND: This study compared incident breast cancer cases in the National Cancer Database (NCDB) and Surveillance, Epidemiology, End Results Program (SEER) to a national population cancer registry.

METHODS: Patients with malignant or in situ breast cancer (BC) 2010-2019 in the NCDB and SEER were compared to the US Cancer Statistics (USCS). Case coverage was estimated as the number of patients in the NCDB/SEER as a proportion of USCS cases.

RESULTS: The USCS reported 3,047,509 patients; 77.5% patients were included in the NCDB and 46.0% in SEER. Case ascertainment varied significantly by patient sex (both registries, p < .001). For males, 84.1% were captured in the NCDB, whereas only 77.5% of females were included. Case coverage in SEER was better for females than males (46.1% vs. 43.5%). Registries varied significantly by race/ethnicity (both p < .001). Case coverage in the NCDB was highest for non-Hispanic White (78.2%), non-Hispanic Black (77.7%), and non-Hispanic Asian or Pacific Islander (72.5%) BC patients, and lowest for Hispanic (56.4%) and non-Hispanic American Indian/Alaska Native (41.1%) patients. In SEER, case coverage was highest for non-Hispanic Asian or Pacific Islander (78.1%) and Hispanic (69.6%) patients and it was significantly lower for all other subgroups (non-Hispanic Black, 44.8%; non-Hispanic White, 42.4%; and non-Hispanic American Indian/Alaska Native, 36.6%).

CONCLUSIONS: National US tumor registries provide data for a large sampling of breast cancer patients, yet significant differences in case coverage were observed based on age, sex, and race/ethnicity. These findings suggest that analyses using these data sets and interpretation of findings should account for these meaningful variances.

ABSTRACT

BACKGROUND: Cochlear dimension measurements are critical in diagnosing and managing congenital sensorineural hearing loss.

OBJECTIVES: To evaluate the feasibility and reliability of an automated landmark approach for measuring cochlear dimensions (A-, B- and H-values).

MATERIAL AND METHODS: Cochlear parameters from 100 patients were measured by MPR, manual three-dimensional and ALPACA. We assessed intra- and inter-observer reliability as well as inter-method reliability. Statistical analyses were conducted to detect differences between the right and left ears, as well as to assess the relevance of the values obtained using ALPACA.

RESULTS: All A-, B-, and H-values measured by the various methods showed a high intra-observer reliability with intra-class correlation coefficients (ICC) ranging from 0.70 to 0.99, and values gained by ALPACA reaching the highest ICC. Inter-method reliability was at a good level with ICC ranging from 0.51 to 0.86. There were no significant differences between the right and left ears’ measured values. Obvious positive correlations existed among cochlear dimensions measured by ALPACA.

CONCLUSIONS AND SIGNIFICANCE: The ALPACA method can be used to measure cochlear dimensions. Values obtained by the method demonstrate high reliability and consistency with a significant reduction in intra-observer variability compared to results from conventional MPR and manual 3D measurements.

ABSTRACT

Maize (Zea mays) is vital as a staple food and livestock feed crop. Yunnan is one of the main maize-producing provinces in China (National Bureau of Statistics, 2022). While corn production in Yunnan is lower than the national average, the development of drought-tolerant varieties has contributed to improving productivity. In August 2021, a new leaf spot disease on maize was observed in Lancang, Yunnan (22°26’38.11″N to 22°48’38.68″N, 99°48’15.13″E to 99°59’20.03″E), causing serious damages to maize production with incidence up to 76.19 %. Initially, small light yellow lesions were seen scattered on diseased maize leaves, round or polygon, measuring 0.3 to 2.0 cm in diameter. In the intermediate phase, these lesions sank, ruptured, and turned white with dark brown borders. In severe cases, they merged into large irregular patches, reaching up to 10 cm, leading to complete leaf necrosis. Small black ascomata were seen on the lesions. Tissue sections reveal perithecium embedded in leaves, measuring 94~145 μm in diameter. Symptomatic tissues were sterilized in 1.5% NaClO for 60s, and washed twice withsterile purified water, then plated on potato dextrose agar (PDA) at 25℃, 90% relative humidity (RH), and a 12-hour light cycle. 6 isolates were obtained from 2 diseased maize cultivars. In 20 days, the colony reached the edge of the PDA plate, the center darkening from white, featuring white aerial mycelium on top and black on the reverse side. Brown ascomata, solitary or clustered, measured 80.1~176.7 × 55.57~138.9 μm. The ellipsoid to oblong ascospores were 17.9~39.7 × 10.9~14.1 μm, and the bitunicate, thick-walled asci were 90.1~133.3 × 26.6~33.5 μm. The genomic DNA was extracted using the Chelex-100 method (Möller et al. 1992). For molecular identification, the ITS, LSU, and β-tubulin (Tub2) genes were amplified using primer pairs ITS1/ITS4 (White et al. 1990), LR0R/LR5 (Vilgalys et al. 1990) and Btub2Fd/Btub4Rd (Woudenberg et al. 2009), respectively. Sequencing was performed by Sangon Biotech (Shanghai) Co., Ltd. The sequenced loci (GenBank accession nos.: LSU, OL687348-53; ITS, OL617009-10, and OL664058-61; Tub2, OL741678-83) of the isolates exhibited 100%/ 99%/ 100% similarities with L. australis genes: LSU, MH868885; ITS, KF381084; Tub2, GU237541, respectively. Using MEGA 11.0, phylogenetic trees were constructed using the maximum-likelihood algorithm on concatenated sequences of LSU, ITS, and Tub2 for isolates LCMB1 to 6. The isolates clustered with two L. australis strains with 100 % bootstrap support (1,000 replicates). The results were consistent with the Bayesian Inference tree. The pathogenicity test used strain LCMB4 on six healthy maize plants during the heading period under natural conditions. Three leaves pre-plant were wounded with sterile sandpaper and sprayed with conidial suspension (106 spores ml-1, diluted in sterilized water) in the greenhouse at 28℃, 90% RH, and a 12-hour light cycle, with sterilized distilled water used for control. Inoculated leaves developed symptoms consistent with the described after 10 days, while control leaves remained symptomless. The same pathogen was re-isolated from the infected leaves, fulfilling Koch’s postulates. Previously, L. australis has been isolated from turfgrass (Mitkowski et al. 2004), Alfalfa (Zhang et al. 2021), soil (Li et al. 2018), and Paris polyphylla var. chinensis (Fu et al. 2019), but not from maize. This is the first report of L. australis causing leaf spot on maize globally.

ABSTRACT

The study involved the estimation of the prevalence of Entamoeba spp. using microscopy and molecular techniques among symptomatic outpatients during April 2021 to March, 2022. Stool samples were collected from 2592 outpatients with amoebiasis symptoms of both sexes and different ages (≤ l to 60). Also, 107 stool samples were taken randomly from asymptomatic individuals and examined microscopically to detect infection with Entamoeba spp. the positive specimens were used for molecular analysis with positive symptomatic samples targeting the 18S rRNA gene by nested PCR. Microscopically 21.68% (562/2592) were positive, for Entamoeba spp. Males showed highest infection rate than females (67.43% vs 32.56%). Ages from 1-10 years showed the highest rate (54.09%), and urban inhabitant had somewhat a higher rate than rural one (58.54% vs 41.45%) which was statistically non-significant(P>0.05). Among asymptomatic individuals, 57% (61/107) were positive for Entamoeba spp. Nested PCR analysis yielded 73% positive samples for Entamoeba spp. with a fragment size of 897 bp. Three fragment sizes were produced, for E. histolytica, E. dispar and E. moshkovskii which were 439, 174 and 553 bps, respectively. Single infection occurred with, E. histolytica in 46%, of symptomatic and 6% of asymptomatic cases, E. dispar in 38% of asymptomatic and 10% of symptomatic cases, E. moshkovskii, reported at very low rate among both groups.

ABSTRACT

BACKGROUND: The Acquired Immune Deficiency Syndrome (AIDS) pandemic has created a lot of devastation over the last four decades and continues to be a public health threat. Anti-retroviral treatment (ART), a group of medications that people who have been diagnosed with the Human Immunodeficiency Virus (HIV) infection take, has been shown to be efficacious and has significantly improved the fight against the disease. In Ghana, women carry a higher prevalence and incidence of HIV. The study’s objectives were to understand the experiences of women living with HIV/AIDS on ART and determine the barriers and enablers for ART uptake from the perspective of both the females living with HIV and their healthcare providers in the Upper East Regional Hospital of Ghana.

METHODS: This was a qualitative study that used interviews to acquire data from women living with HIV on the perceived barriers and enablers for ART. The Upper East Regional Hospital in Ghana was the study site. We used a phenomenological approach to explore the lived experiences, perceptions, and meanings associated with ART among women. We collected data until we reached thematic saturation, interviewing a total of sixteen women living with HIV. We conducted a focus group discussion with nine healthcare workers providing care at the ART clinic. Data were analysed using thematic analysis.

RESULTS: Women living with HIV and their healthcare providers viewed an environment that provided encouragement and support from healthcare workers and patients’ relatives, the ability to conceal HIV status, peer counselling, and the perceived benefits of therapy as enablers of ART uptake and medication adherence. The following were barriers to ART uptake and adherence: ill health, forgetfulness, long distances to ART clinics, cultural and spiritual beliefs, and fear of stigma.

CONCLUSIONS: Enablers of ART uptake should be expanded upon and encouraged so that women living with HIV/AIDS can access drugs in a timely and stress-free manner. On the other hand, the barriers identified can be addressed through education, the expansion of healthcare infrastructure, and the economic empowerment of women.

ABSTRACT

BACKGROUND: This study investigated the characteristics of Monson’s sphere in Chinese young adult females with individual normal occlusion to provide a reference for oral rehabilitation in prosthodontic and orthodontic treatments.

METHODS: Points at the dental cusps and incisal edges were selected from 51 digital mandibular dental models of Chinese young adult females (aged 18-22 years) with individual normal occlusion. Monson’s spheres were fitted to the selected points based on the least-squares principle and the radii were calculated. The deviation of each selected point from its relative spherical surface was also calculated. The radii and deviations of these points were examined using conventional descriptive statistics and distributions of the most deviated points inside and outside the spheres were analyzed.

RESULTS: The mean radius of Monson’s sphere in Chinese young adult females was 79.60 ± 14.13 mm. The deviation of each selected point from its relative sphere surface was 0.38 ± 0.30 mm. The maximum deviations inside and outside the sphere were 0.93 ± 0.25 mm and 0.95 ± 0.30 mm, respectively. The most deviated points outside the spheres were mainly distributed at the distolingual cusps of the mandibular second permanent molars (31.37%), while those inside the spheres were mainly distributed at the mesiolingual cusps of the mandibular first permanent molars (45.10%).

CONCLUSIONS: The radius of Monson’s sphere in Chinese young adult females was smaller than the classic four-inch value suggested by Monson. Deviation was observed from all selected points to their Monson’s sphere surface, with the most deviated points distributed primarily in the molar region.

ABSTRACT

BACKGROUND: Epilepsy is a major global health challenge, affecting approximately 50 million people across the globe and resulting in significant economic impacts on individuals and society. Oxidative stress is implicated in the pathogenesis of epilepsy, highlighting the potential of antioxidant-rich dietary patterns in offering preventive and protective benefits by mitigating oxidative stress. The Composite Dietary Antioxidant Index (CDAI) provides a measure for assessing dietary antioxidant intake, yet its link to epilepsy remains unexplored.

METHODS: Our analysis utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning 2013 to 2018, including 20,180 screened participants. Weighted logistic regression models were employed to examine the association between the CDAI and epilepsy prevalence. Non-linear associations were explored through restricted cubic splines (RCS), and the relationships between individual antioxidant components within the CDAI and epilepsy were also assessed.

RESULTS: After adjusting for potential confounders, a negative association between the CDAI and epilepsy was suggested (OR = 0.991; p = 0.087, 95% CI [0.819,1.014]). Stratification of CDAI into quartiles revealed a significantly reduced risk of epilepsy in higher CDAI quartiles (Q3 and Q4) compared to the lowest quartile (Q1) (Q3: OR = 0.419; p = 0.030, 95% CI [0.192, 0.914]; Q4: OR = 0.421; p = 0.004, 95% CI [0.239, 0.742]), with a significant trend observed across quartiles (p for trend = 0.013). RCS analysis suggested a nonlinear association between CDAI levels and epilepsy (non-linear p = 0.049), which, however, was not statistically significant after full adjustment (non-linear p = 0.103). Additionally, significant negative correlations with epilepsy were observed for vitamin A and zinc (Vitamin A: OR = 0.999; p = 0.012, 95% CI [0.998, 1.000]; Zinc: OR = 0.931; p = 0.042, 95% CI [0.869, 0.997]).

CONCLUSIONS: Our research indicates a correlation where higher CDAI levels correspond to a reduced risk of epilepsy. Therefore, embracing a diet rich in antioxidants could be beneficial in preventing epilepsy. This finding holds considerable potential for shaping future strategies in both epilepsy prevention and treatment.

ABSTRACT

BACKGROUND: The triglyceride glucose (TyG) index is a cutting-edge and highly effective marker of insulin resistance, a crucial factor in the development and exacerbation of diabetic kidney disease (DKD). To date, there has been limited research on how the triglyceride-glucose (TyG) index affects the outlook for patients suffering from DKD.

METHODS: In this multicenter retrospective cohort study, the analysis recruited 2,203 DKD patients from the National Health and Nutrition Examination Survey (NHANES) dataset, which covers the US from 2001 to 2018. The research applied a Cox proportional hazards model with multiple variables to investigate the association of the TyG index with mortality outcomes. Restricted cubic splines (RCS) and methods for analyzing threshold effects were employed to identify possible non-linear relationships.

RESULTS: Over nearly 19 years of follow-up, this study captured data on 753 all-cause and 231 cardiovascular disease-specific fatalities. Sophisticated statistical methods, including RCS and smoothing curve adjustments via penalized splines, helped identify distinctive patterns: The baseline TyG index was observed to have a U-shaped pattern related to overall mortality and an L-shape with cardiovascular diseases(CVD) mortality among individuals with DKD. Notably, TyG index below 9.15 for overall mortality and 9.27 for CVD mortality were linked to reduced death rates (HR = 0.65, 95% CI = 0.52-0.82 for all-cause; HR = 0.58, 95% CI = 0.43-0.83 for CVD). On the other hand, TyG index exceeding these benchmarks (greater than 9.15 for all-cause and 9.27 for CVD) correlated with increased all-cause mortality risks (HR = 1.21, 95% CI = 1.02-1.43) and showed a non-significant change in CVD mortality risks (HR = 1.07, 95% CI = 0.83-1.38).

CONCLUSIONS: This study emphasizes the non-linear linkage involving the TyG index and death rates due to CVD and other factors in patients with DKD, demonstrating its effectiveness in estimating potential adverse events within this demographic.

ABSTRACT

BACKGROUND: Childhood obesity has become a major global health problem. Obesity is associated with major health problems, such as diabetes, hypertension, dyslipidemia, cardiovascular disease. Obesity is also considered a risk factor for Pseudotumor cerebri (PTC). The present study aimed to investigate the relationship between body mass index (BMI), and cerebrospinal fluid (CSF) pressure in patients with pseudotumor cerebri.

METHODS: A total of 48 children diagnosed with PTC, who were aged < 18 years and followed up in the pediatric clinic were included in the retrospective study. National BMI percentile curves were used for reference. We investigated statistically the relationship between BMI, clinical and laboratory results, and CSF pressure in patients.

RESULTS: Of total patients 27 were female (56.25%) and 21 were male (43.75%). With regard to the BMI percentile, 20 (41.67%) were overweight or obese. CSF pressure was higher in overweight and obese patients compared to children with BMI in normal ranges (p < 0.05). A statistically significant positive correlation was also observed between BMI and CSF pressure values and between monocyte and CSF values (p < 0.05).

CONCLUSIONS: The results of the present study indicate a direct relationship between CSF pressure and BMI in children with PTC. Appropriate diet, exercise, and medical treatment in overweight and obese children can make a significant contribution to the treatment of PTC. Additionally, a significant correlation was observed between CSF pressure and monocyte levels.
