Objectives: To identify the right interventions for the right heart failure (HF) patients in the real-world setting using machine learning (ML) trained on individual-level clinical data linked with social determinants of health (SDOH) data. Methods: In this retrospective cohort study, point-of-care claims data from Komodo Health and SDOH data from the National Health and Wellness Survey (NHWS), from January 2014–December 2020, were linked. Data mining was conducted using K-means clustering, an ML tool. Komodo Health data were used to access longitudinal data for the selected patient cohorts and crosssectional data from NHWS for additional patient information. The primary outcome was HF-related hospitalizations; secondary outcomes, all-cause hospitalization and all-cause mortality. Use of digital healthcare (DHC)on-DHC interventions and related outcomes were also assessed. Results: The study population included 353 HF patients (mean age, 63.5 years; 57.2% women). The use of non-DHC (75.9%–81.9%) and DHC (4.0%–9.1%) interventions increased from baseline to followup. Overall, 17.0% of patients had HF-related hospitalizations (DHC, 6.9%; non-DHC, 16.5%) and 45.0% had all-cause hospitalization (DHC, 75.0%; non-DHC, 50.9%). Two archetypes with distinct patient profiles were identified. Archetype 1 (vs. 2) characterised by older age, greater disease severity, more comorbidities, more medication use, took steps to prevent heart attack/problems, had better lifestyle, higher HF-related hospitalizations (18.3% vs. 16.3%) and lower all-cause hospitalizations (42.9% vs. 46.3%). The trends remained the same regardless of the intervention type. Conclusions Identification of patient archetypes with distinct profiles can be useful to understand underlying disease subtypes, identify specific interventions, predict clinical outcomes, and define the right intervention for the right patient.

Purpose: This study compared the long-term outcomes and complications associated with sutured and suture-less scleral fixed intraocular lenses (SFIOLs), the two primary surgical techniques for scleral fixation of IOLs. Methods: A total of 90 patients were included in the study with 46 in the sutured group and 44 in the suture-less group. These patients underwent SFIOL between January 2019 and June 2023 due to IOL dislocation, aphakia, or crystalline lens dislocation. Collected data included age, gender, axial length, operative time, best corrected visual acuity (BCVA), intraocular pressure (IOP), refractive value, refractive error, ocular residual astigmatism, IOL dislocation, recurrent IOL dislocation, IOL tilt, and IOL iris capture. Changes from preoperative status to 1 year postoperatively were assessed. Results: No significant differences were found between the sutured and suture-less groups regarding preoperative BCVA, IOP, and refractive values. However, the suture-less group demonstrated significantly better BCVA at both 1 week and 1 month postoperatively compared to the sutured group (p = 0.010, 0.015, respectively). The refractive error in the suture-less group was also significantly lower at 1 week postoperatively (p = 0.020). Ocular residual astigmatism was consistently lower in the suture-less group across all postoperative intervals (p < 0.001). While the suture-less group showed a shorter average surgical time, there was greater variability in operative duration (p < 0.001, 0.024, respectively). Additionally, a longer axial length was associated with an increased incidence of IOL iris capture (p = 0.004). Conclusions Suture-less SFIOL is associated with shorter operative times, although with greater variability. Patients in the suture-less group experienced faster BCVA improvement, reduced refractive error, and lower ocular residual astigmatism compared to those in the sutured group.

Purpose: The association between the healing of an injured anterolateral ligament (ALL) and residual pivot-shift following anterior cruciate ligament (ACL) reconstructions is rarely reported. This study analyzed the relationship between unhealed ALL and residual pivot-shift after an ACL reconstruction. Materials and Methods: The inclusion criteria were patients who underwent autologous hamstring ACL reconstructions within 6 weeks after injury from January 2008 to March 2021. Preoperative ALL injuries and postoperative ALL healing were graded according to the magnetic resonance imaging classification, with postoperative magnetic resonance imaging performed 7.8 months after surgery on average. The patients were categorized based on postoperative ALL healing, and the clinical scores (Lysholm score and Tegner activity scale) and knee stability (Lachman test and pivot-shift test) were assessed at the 1-year postoperative follow-up. Results: One hundred and forty-five patients were enrolled in this study. One hundred and twenty-eight (88.3%) patients had a concomitant ALL injury. Among 86 patients with preoperative grade B, 16 (18.6%) patients showed grade 1 (good), and 70 (81.4%) showed grade 2 (partial) ALL postoperatively. Among the 42 patients with preoperative grade C (complete tear), 1 (2.4%) patient showed grade 1 (good), 21 (50.0%) showed grade 2 (partial), and 20 (47.6%) showed grade 3 (non-visualized) ALL. Preoperative grade C was significantly associated with a higher incidence of grade 3 (non-visualized) postoperatively than the other groups (p<0.001). Postoperatively, the Lachman test, KT-1000 (MEDmetric Corp.) arthrometer (side-to-side difference), Lysholm score, and Tegner activity scales did not show a significant difference among the intact, grade 1, grade 2, and grade 3 ALL groups. The pivot-shift test showed a significant difference between the ALL grades (p=0.001). Grade 3 ALL group showed a higher incidence of pivot-shift than the intact, grade 1, and grade 2 ALL groups. Conclusion Patients with preoperative grade C had a higher rate of grade 3 postoperatively compared to the other groups. In addition, the grade 3 group had a significantly higher incidence of a pivot-shift. Therefore, in cases of ACL injuries with concomitant complete ALL tears, ALL reconstruction should be considered during ACL reconstruction.

Vertigo and dizziness are amongst the most frequent presenting symptoms in the emergency room, accounting for up to 4% of all emergency consultations. The broadness of their differential diagnosis and the often transient nature of these symptoms pose a significant challenge to the treating physician. Combining various subtle oculomotor signs at the bedside has been very successful in distinguishing peripheral from central causes in acutely dizzy patients meeting diagnostic criteria for the acute vestibular syndrome (i.e., acute and prolonged vertigo or dizziness accompanied by nausea or vomiting, gait imbalance, motion intolerance, and [not mandatory] nystagmus). While the diagnostic accuracy of the HINTS (Head-Impulse—Nystagmus—Test-of-Skew) algorithm has been studied extensively, less is known about the value of various nystagmus patterns seen at the bedside in patients with an acute vestibular syndrome.Here we review both spontaneous and triggered presenting nystagmus patterns and discuss their impacts and limitations, including primary-gaze horizontal, vertical, and torsional nystagmus, nystagmus during eccentric gaze, and nystagmus triggered by stimuli such as headshaking, hyperventilation, positional testing, vibration, and the Valsalva maneuver. We conclude that the usefulness of nystagmus patterns in discriminating peripheral and central causes strongly depends on the pattern seen and the type of testing performed, being highly predictive of a central cause for torsional and vertical spontaneous nystagmus, downbeat, or apogeotropic horizontal and treatment-refractory positional nystagmus. The predictive value for central causes was moderate only for vertical nystagmus after horizontal head-shaking (“perverted” head-shaking nystagmus) since it can also occur in peripheral cases, while the predictive value was low for vibration-induced nystagmus and Valsalva-induced nystagmus.

PURPOSE: The purpose of this study was to compare the surface characteristics and healing patterns after implantation of implants treated with SLA and those treated with both SLA and femtosecond laser. MATERIALS AND METHODS: A total of 10 male New Zealand white rabbits were used to compare recovery levels between implants treated with SLA (SLA group) and those treated with both SLA and femtosecond laser (SF group). The implants’ surface characteristics were determined through topographic evaluation, element analysis, surface roughness, and wettability evaluation. In total, 4 implants were placed in each rabbit (2 in each tibia), with 20 implants per treatment group. Using the implant stability quotient (ISQ), marginal bone volume, and histological analysis (bone-to-implant contact (BIC), bone volume/tissue volume (BV/TV)), and post implantation outcomes were assessed. Outcome data were analyzed using independent t-tests, Mann-Whitney U tests, Wilcoxon signed-rank tests, and one-way ANOVA (α = 0.05). RESULTS: No significant differences were noted between SLA and SF groups in terms of ISQ, marginal bone volume, BIC, and BV/TV (P > .05). However, significant differences in ISQ were observed within each group over time (P < .05). Furthermore, significant differences were noted in the marginal bone volume of the SF group (P < .05) and the BV/TV of the SLA group between weeks 4 and 6 (P < .05). CONCLUSION Surface treatment via SLA and femtosecond laser is feasible compared with SLA treatment alone in terms of ISQ, marginal bone volume, BIC, and BV/TV. However, further clinical research is warranted.

PURPOSE: The purpose of this clinical study was to evaluate the extent of intraoral occlusal adjustment required for zirconia crowns designed with a dynamic jaw motion tracking method compared to a conventional approach. MATERIALS AND METHODS: Fifteen patients needing zirconia crown restorations in the anterior or posterior regions participated in this study. Following tooth preparation, dynamic jaw motion tracking records were gathered using a tracking device. These records were imported into computer-aided design software and aligned with scanned upper and lower jaw data to design each crown's occlusal surface. Two crowns were fabricated for each patient: one using motion tracking data and another without it. Crowns were scanned pre- and post-adjustment following standard protocols. The scanned data were analyzed with 3D inspection software to calculate occlusal adjustments in the segmented occlusal area as root mean square values, with a paired t-test used for statistical analysis (α = 0.05). RESULTS: Crowns designed with motion tracking data required significantly less intraoral occlusal adjustment than those designed conventionally (P = .028). CONCLUSION Dynamic jaw motion tracking in crown design reduces the extent of intraoral occlusal adjustment, potentially enhancing clinical efficiency.

A significant portion of newly diagnosed lung cancer cases occurs in populations exposed to air pollution. The World Health Organization has identified air pollution as a human carcinogen, prompting many countries to implement monitoring systems for ambient particulate matter (PM). PM is composed of a complex mixture of organic and inorganic particles, both solid and liquid, that are found in the air. Given the carcinogenic properties of PM and the high prevalence of lung cancer among exposed populations, exploring their connection and clinical implications is critical for effectively preventing lung cancer in this group. This review explores the relationship between ambient PM and lung cancer. Epidemiological studies have demonstrated a dose-response relationship between PM exposure and lung cancer risk. PM exposure induces oxidative stress, disrupts the body’s redox balance, and causes DNA damage, which is a crucial factor in cancer development. Recent findings on the strong correlation between ambient PM and adenocarcinoma highlight the importance of understanding the specific molecular and pathological mechanisms underlying pollution-related lung cancer. In addition to efforts to control emission sources at the international level, a more individualized approach is essential for preventing PM-related lung cancer.

The initial molecular cytogenetic characteristics of blasts plays a significant role in determining the treatment course of B-cell acute lymphoblastic leukemia (B-ALL).B-ALL with intrachromosomal amplification of chromosome 21 (iAMP21) has been well known to have unfavorable prognosis. Also, there are previously recognized germline mutations that increase the risk of ALL, such as trisomy 21, Down syndrome. This case report is about a 16-year-old girl who presented with lymphadenitis, purpura, and fever followed by initial lab of elevated white blood cell with blasts.She had some notable facial features, but no typical Down syndrome related one.Bone marrow biopsy and fluorescence in situ hybridization finalized the diagnosis as B-ALL with iAMP21, high-risk group. The minimal residual disease-negative complete remission was achieved after the induction chemotherapy with Korean multicenter high-risk protocol. However, abnormal karyotype was sustained in bone marrow. Microarrays with her buccal swab raised the possibility that the abnormal karyotype was not from the leukemic blasts but rather from the germline. Although she underwent scheduled chemotherapy uneventfully as slow early responder type, thrombocytopenia and abnormal karyotype persisted, leading to the diagnosis of acute myeloid leukemia. Additional chemotherapy and peripheral blood stem cell transplantation was performed which resulted in engraftment. This case highlights the discovery of a constitutional genetic aberration, which played like a silent yet critical background factor for B-ALL with iAMP21. As the number of reported cases are limited, the role of germline chromosome 21 mutation as the indicator for prognosis of B-ALL should be studied further.

Background: To identify the optimal surgical technique for single-level anterior cervical discectomy and fusion (ACDF), this study compared surgical outcomes and incidence of adjacent segment degeneration (ASD) in patients undergoing single-level ACDF using cage alone single-level fusion and plate fixation techniques. Methods: This single-center retrospective study (2003–2018) included patients who underwent single-level ACDF with either plate fixation (PLATE) or cage (CAGE) alone. The radiologic and clinical outcomes between the 2 surgical groups were compared over a 4-year follow-up period. Outcomes of interest included parameters related to range of motion, sagittal alignment, as well as fusion, subsidence, and ASD rates. Clinical outcomes were evaluated using the Neck Disability Index (NDI) and visual analog scale (VAS) for pain. Dysphagia and hoarseness rates were estimated based on medical records. Results: Forty-seven patients were included (n=17 in CAGE group). In the CAGE group, 94.1% of the patients had Bridwell grade 1 or 2, compared to 83.3% in the PLATE group (p = 0.396). Subsidence occurred in 12.5% and 3.6% of the CAGE and PLATE cases, respectively (p = 0.543). Segmental kyphosis progressed in the CAGE group compared to the PLATE group at 12, 24, and 48 months (p < 0.001). Radiographic ASD was observed in 41.2% and 30.0% of patients in the CAGE and PLATE groups, respectively, with a higher incidence in the upper segments for both groups. Preoperative NDI scores were similar between the groups; however, postoperatively, the CAGE group had significantly lower NDI scores (3.50 ± 2.74 vs. 8.00 ± 5.81) at 4 years (p = 0.020). Neck pain VAS scores also showed significant improvement in the CAGE group (2.33 ± 2.94) compared with that in the PLATE group (3.07 ± 2.31) at 4 years (p = 0.045). Both groups showed comparable arm pain VAS scores at 2 and 4 years postoperatively. Postoperative dysphagia occurred in 1 patient in the PLATE group, resolving almost completely by 1 year. Conclusions Single-level ACDF using a cage alone technique demonstrated favorable radiologic and clinical outcomes overall compared to plate-augmented ACDF. However, plate augmentation is recommended for patients with severe cervical kyphosis or those at high risk of subsidence.
