Determinants of Multiple Brooding in Barn Swallows (Hirundo rustica) in Atlantic Canada

Multiple brooding is an important component of reproductive success in many birds and the frequency of this behaviour has been linked to intrinsic (e.g., age, experience) and extrinsic factors (e.g., weather, food availability). When extrinsic factors drive multiple brooding, it may be possible to identify conservation actions to support multiple-brooded species at risk. The Barn Swallow (Hirundo rustica Linnaeus, 1758), is a multiple-brooded aerial insectivore, currently listed as Threatened on Canada’s Species at Risk Act. We examined how weather, landcover, the presence of livestock and metal roofs (with associated heat) above nests affected the likelihood of multiple brooding in Barn Swallows nesting in Nova Scotia and New Brunswick, Canada. We found that sites with a lower proportion of open habitats, including pastures, hayfields, and lawns, within the typical foraging range (i.e., 400 m) of nests, were associated with a higher probability of multiple brooding. Also, multiple brooding may be less likely in windy conditions. We found no effect of proportion of other landcover types, weather conditions, livestock or metal roofs above nests. When possible, decreasing the proportion of open habitats around breeding sites could result in higher rates of multiple brooding, and in turn, help slow population declines.

Infantile and Very Early Onset Inflammatory Bowel Disease: A Multicenter Study.

This study described disease characteristics and long-term outcomes in patients diagnosed with very early onset inflammatory bowel disease (VEOIBD) (diagnosed before 6 years of age) and infantile-IBD (before 2 years). Cases from 21 centers worldwide diagnosed with VEOIBD (2008-2018), with minimum 2 years of follow-up, were retrospectively reviewed. The cohort included 243 patients (52% males, median follow-up of 5.8 [range 2-18] years, including 69 [28%]) with infantile-IBD. IBD subtypes included Crohn's disease (CD), ulcerative colitis (UC), or IBD-unclassified (IBDU) in 30%, 59%, and 11%, respectively. Among patients with CD, 94% had colonic involvement, and among patients with UC/IBDU, 75% had pancolitis. Patients with infantile-IBD presented with higher rates of IBDU, lower hemoglobin and albumin levels, and higher C-reactive protein, and had lower response rates to first-induction therapy and corticosteroids therapy (P < .05 for all). Colectomy and diversion surgeries were performed in 11% and 4%, respectively, with no significant differences between age groups. Corticosteroid-free remission rates were 74% and 78% after 3 and 5 years, respectively, and 86% at end of follow-up. Genetic testing was performed in 96 (40%) patients. Among tested population, 15 (16%) were identified with monogenic disease. This group demonstrated lower response rates to induction therapies, higher rates of surgical intervention, and higher rates of major infections (P < .05 for all). Patients with VEOIBD, including infantile-IBD, exhibit low rate of complications and surgical interventions at the long term. Patients with monogenic IBD are at risk for more severe disease course.

Serious treatment-emergent adverse events in chronic low back pain patients treated with buprenorphine or oral opioids: a retrospective commercial claims analysis.

Aim: Explore the safety of Belbuca® (buprenorphine buccal film), buprenorphine transdermal patches and oral opioids for chronic low back pain (cLBP) treatment. Methods: The retrospective analysis of the MarketScan Commercial database (2018-2021) included treatment-naive cLBP adults. The first date of buprenorphine (Belbuca and transdermal patch) or opioid prescription was index date. Cohorts were defined based on the index medication. Observation included a 6-month pre-index period, while post-index lasted until the end of continuous insurance coverage. There were 44 relevant treatment-emergent adverse events (TEAEs) identified in the literature. Incidence rate ratio (IRR) and incidence rate difference (IRD) were used to compare serious TEAE rates (in 1000 person-years) between cohorts. Propensity-score matching minimized the selection bias. Results: Buprenorphine had lower rates of 15 serious TEAEs than oral opioids (all p≤0.037), while higher rates only for serious dizziness (IRR 2.44, p=0.011; driven by Belbuca), opioid abuse/dependence (IRR 3.13, p=0.004; driven by patches) and cholecystitis (IRD 20.25, p=0.044; an outlier). Additionally, a comparison between Belbuca and oral opioids showed lower rates of 13 serious TEAEs (all p≤0.024) and a higher serious dizziness rate (IRR 3.17, p=0.024). Although the rates of serious opioid abuse/dependence were similar (24.60 vs 26.93, p=0.921), all Belbuca patients and none of the opioid patients had a positive history of these events. Belbuca also had lower rates of five serious TEAEs than transdermal patches (all p≤0.018), including a serious opioid abuse/dependence (IRR 0.04, p<0.001), but higher rates of serious cholecystitis (IRD 52.17, p=0.035; an outlier) and suicidal ideation (IRD 156.50, p<0.001; an outlier). Conclusion: Buprenorphine had a better safety profile than oral opioids in cLBP treatment. Belbuca showed a more favorable TEAE profile than buprenorphine transdermal patches and oral opioids.

Etiology-Specific Effects of Impaired Functional Status on Liver Transplant Outcomes.

Pre-liver transplant (LT) functional status is an important determinant of prognosis post LT. There is insufficient data on how functional status affects outcomes of transplant recipients based on the specific etiology of liver disease. We stratified LT recipients by etiology of liver disease to evaluate the effects of functional status on post-LT prognosis in each subgroup. 2005-2019 United Network for Organ Sharing (UNOS) Standard Transplant Analysis and Research (STAR) was used to select patients with liver transplant. A total of 14,290 patients were included in the analysis. These patients were stratified by functional status according to Karnofsky Performance Scale (KPS) score: no assistance, some assistance, or total assistance. They were then further divided into six diagnosis categories: metabolic dysfunction-associated steatotic liver disease (MASLD), hereditary disorders, hepatitis C, hepatitis B, autoimmune disease (AID), and alcoholic liver disease (ALD). Primary endpoints included all-cause mortality and graft failure, while secondary endpoints included organ-specific causes of death. Those under the age of 18 and those with non-whole liver or prior liver transplantation were excluded. Patients with MASLD requiring some assistance (aHR: 1.57, 95% CI 1.03-2.39, p = 0.04) and those requiring total assistance (aHR: 2.32, 95% CI 1.48-3.64, p < 0.001) had higher incidences of graft failure compared to those requiring no assistance. Those with MASLD requiring total assistance had a higher all-cause mortality rate than those needing no assistance (aHR: 1.62, 95% CI 1.38-1.89, p < 0.001). Patients with hereditary causes of liver disease showed a lower incidence of all-cause mortality in recipients needing some assistance compared with those needing no assistance (aHR: 0.52, 95% CI 0.34-0.80, p = 0.003). LT recipients with hepatitis C, AID, and ALD all showed higher incidences of all-cause mortality in the total assistance cohort when compared to the no assistance cohort. For the secondary endpoints of specific cause of death, transplant recipients with MASLD needing total assistance had higher rates of death due to general cardiac causes, graft rejection, general infectious causes, sepsis, general renal causes, and general respiratory causes. Patients with MASLD cirrhosis demonstrated the worst overall outcomes, suggesting that this population may be particularly vulnerable. Poor functional status in patients with end-stage liver disease from hepatitis B or hereditary disease was not associated with a significantly increased rate of adverse outcomes, suggesting that the KPS score may not be broadly applicable to all patients awaiting LT.

Real-world evidence of characteristics and factors influencing herbal medicine use for weight loss in adults

BackgroundObesity imposes a significant socioeconomic burden owing to its high prevalence. In response to the adverse outcomes associated with conventional pharmacotherapy and the challenges of low adherence to lifestyle interventions, herbal medicine has surfaced as an actively utilized approach for weight loss. Therefore, this study aimed to analyze the characteristics and influencing factors of herbal medicine users for weight loss in adults.MethodsOverall, 22,080 participants were included based on data from the Korea National Health and Nutrition Examination Survey from 2010 to 2019. Simple logistic regression analyses were used to derive the associations between herbal medicine use for weight loss and individual characteristics. Three models were constructed utilizing multiple logistic regression analyses to assess the associations between herbal medicine use for weight loss and the combined characteristics of predisposing, enabling, and need factors according to Andersen’s model.ResultsIn the full adjustment model, women, younger adults, those with higher incomes, and individuals reporting higher levels of perceived stress were more prone to use herbal medicine for weight loss in the past year. Adults who identified body image as being fat/very fat, those who consumed alcohol, and those classified as severely obese by body mass index were also more prone to use herbal medicine for weight loss. In particular, adults with a higher rate and amount of weight loss in the past year were more likely to use herbal medicine for weight loss compared to those experiencing weight gain/no changes/loss of 0–3 kg.ConclusionOur study was the first to derive the characteristics and influencing factors of herbal medicine users for weight loss among adults. These findings hold significant promise for informing future research endeavors and policy decision-making for effective resource distribution for obesity treatment.

The Impact of Graduate Record Exam Threshold Scores in Disqualifying Underrepresented Ethnic-Racial Minority Applicants for Admission to a Doctor of Physical Therapy Program.

A growing number of graduate-level health professions education programs in the United States are discontinuing the use of the Graduate Record Exam (GRE) in their admissions requirements amidst concerns that its use puts Underrepresented Racial Minority (URRM) applicants at a disadvantage. This retrospective cross-sectional study analyzes the association between ethnic-racial selection and the reasons for disqualification among applicants to a public Doctor of Physical Therapy (DPT) program that used a minimum grade point average (GPA), and Analytic Writing and Quantitative Reasoning GRE minimum threshold scores to qualify applicants. There is evidence across the health professions literature that both GRE scores and GPA are associated with success on licensure examinations and academic performance. However, these variables also tend to disadvantage URRM applicants in gaining admissions to postgraduate health care fields, including physical therapy. All applicants (N = 4,797) to a single DPT program from a 9-year period were included. Racial and ethnic self-selections, GRE scores, and prerequisite GPA were coded for each applicant and classified for meeting qualifying criteria. The URRM applicants were disqualified based on GRE scores alone (P < .001) and in combination of GRE and GPA at a statistically significantly (P < .001) higher rate than Overrepresented Racial Group (ORRG) applicants, although the associations were negligible or weak. Compared with ORRG applicants, URRM applicants were at a statistically significant disadvantage because of the GRE threshold scores requirement. Furthermore, this study demonstrated that use of GRE minimum threshold scores disproportionately reduced URRM applicants in the qualified applicant pool. This investigation can be used as a model to inform holistic admission decisions regarding the use of academic variables to achieve the diversity and success goals of the program.

Nafcillin-induced thrombocytopenia: An uncommon complication

Drug-induced thrombocytopenia is a challenging clinical dilemma that is often overlooked. Nafcillin is a beta-lactam anti-staphylococcal penicillin antibiotic used as a first-line treatment for methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia and severe infections. Nafcillin has been associated with a higher rate of premature antibiotic discontinuation than cefazolin. Here we report a 58-year-old woman with multiple comorbid conditions who presented with a prosthetic right hip joint infection due to MSSA and was treated with nafcillin but developed profound thrombocytopenia due to a possible nafcillin side effect on the 14th day of therapy. Thrombocytopenia resolved after discontinuation of nafcillin, and the patient was treated successfully with cefazolin.

Thoracolumbar fracture and spinal cord injury in blunt trauma: a systematic review, meta-analysis, and meta-regression.

To determine the pooled rate of thoracolumbar fractures and SCI in blunt trauma patients. A systematic review and meta-analysis of observational studies were performed. The search was conducted in the PubMed, Scopus, Web of Science, and Embase databases. The authors screened and selected studies based on predefined inclusion and exclusion criteria. Studies were then evaluated for risk of bias using the JBI checklist. The pooled event rate and 95% confidence intervals (CI) were calculated using random effects models. Subgroup and meta-regression analyses were performed to explore sources of heterogeneity. Twenty-one studies fulfilled the selection criteria. The pooled rate of TL fractures was 8.08% (CI = 6.18-10.50%), with high heterogeneity (I2 = 99.98%, P < 0.001). Thoracic and lumbar fractures accounted for 45.23% and 59.01% of the TL fractures, respectively. Meta-regression revealed that the midpoint of the study period was a significant moderator. The pooled event rate of SCI among TL fracture patients was 15.81% (CI = 11.11 to 22.01%) with high heterogeneity (I2 = 98.31%, P < 0.001). The country of study was identified as a source of heterogeneity through subgroup analysis, and studies from the United States reported higher rates of SCI. Meta-regression revealed that the critical appraisal score was negatively associated with event rate. Our study evaluated the rate of TL fractures in multiple countries at different time points. We observed an increase in the rate of TL fractures over time. SCI results also seemed to vary based on the country of the original study.

General extenders in New Zealand Englishes

AbstractThis paper provides insight into the use of general extenders (e.g., and stuff, or something and and whatnot) in New Zealand Englishes as spoken by Māori and New Zealand European (Pākehā) New Zealanders. Based on audio‐recorded data of prompted co‐constructed narrations, the article explores the types of general extenders and their rate of occurrence in both groups. Contrary to expectations, the group of Pākehā New Zealanders shows a significantly higher rate of using general extenders compared to the Māori participants while the preferred types of general extenders overlap to a large extent among the two speaker groups. A close‐up on the by far most widely spread general extender in both groups (and stuff) unveils interesting patterns of variation across the Māori and Pākehā New Zealanders.

Neonatal abstinence syndrome and infant mortality and morbidity: a population-based study

BackgroundInfant health among newborns with neonatal abstinence syndrome (NAS) has been understudied. We examined infant mortality and hospitalizations among infants diagnosed with NAS after birth.MethodsAll live births in British Columbia (BC), Canada, for fiscal years from 2004–2005 to 2019–2020, were included (N = 696,900). NAS was identified based on International Classification of Diseases, version 10, Canadian modification (ICD-10-CA) codes; the outcomes included infant death and hospitalizations during the first year of life, ascertained from BC linked administrative data. Generalized estimating equation models were used to adjust for maternal factors.ResultsThere were 2,439 infants with NAS (3.50 per 1,000 live births). Unadjusted for other factors, infant mortality was 2.5-fold higher in infants with vs. without NAS (7.79 vs. 3.08 per 1,000 live births, respectively) due to increased post-discharge mortality NAS (5.76 vs. 1.34 per 1,000 surviving infants, respectively). These differences diminished after adjustment: adjusted odds ratio (AOR) for infant death was 0.85 [95% confidence interval (CI): 0.52–1.39]; AOR for post-discharge death was 1.75 (95% CI 1.00–3.06). Overall, 22.3% infants with NAS had at least one hospitalization after post-neonatal discharge, this proportion was 10.7% in those without NAS. During the study period, discharge to foster care declined from 49.5% to 20.3% in infants with NAS.ConclusionUnadjusted for other factors, infants with NAS had increased post-discharge infant mortality and hospitalizations during the first year of life. This association diminished after adjustment for adverse maternal and socio-medical conditions. Infants with NAS had a disproportionately higher rate of placement in foster care after birth, although this proportion declined dramatically between 2004/2005 and 2019/2020. These results highlight the importance of implementing integrated care services to support infants born with NAS and their mothers during the first year of life and beyond, even though NAS itself is not independently associated with increased infant mortality.

Wearable Devices, Health Care Use, and Psychological Well-Being in Patients With Atrial Fibrillation.

Wearables are increasingly used by patients with atrial fibrillation (AF) for symptom monitoring and health management, but their impact on patient health care use and psychological well-being is not well understood. In this retrospective, propensity-matched study of patients with AF, survey and electronic health record data were merged to compare AF-specific health care use (outpatient/inpatient visits, rhythm-related testing, and procedures) and informal health care use (telephone calls and patient portal messages) over a 9-month period between wearable users and nonusers. We also examined the effects of wearable cardiac monitoring features (eg, heart rate alerts, irregular rhythm notification, and ECG) on patient behavior and well-being. Of 172 patients with AF in this analysis (age, 72.6±9.0 years; 42% women), 83 used a wearable. Compared with nonusers, wearable users reported higher rates of symptom monitoring and preoccupation (P=0.03) and more AF treatment concerns (P=0.02). Moreover, 20% of wearable users experienced anxiety and always contacted their doctors in response to irregular rhythm notifications. After matching, AF-specific health care use was significantly greater among wearable users compared with nonusers (P=0.04), including significantly higher rates of ECGs, echocardiograms/transesophageal echocardiogram, and ablation. Wearable users were also significantly more likely to use informal health care resources compared with nonusers (P=0.05). Wearables were associated with higher rates of symptom monitoring and preoccupation, AF treatment concerns, AF-specific health care use, and use of informal health care resources. Prospective, randomized studies are needed to understand the net effects of wearables and their alerts on patients, providers, and the health care system.

Impact of Soil Management Practices on Soil Culturable Bacteriota and Species Diversity in Central European a Productive Vineyard under Warm and Dry Conditions

Sustainable management practices are crucial for the longevity of a monoculture vineyard, especially in the context of a changing climate. Therefore, soil management practices in a vineyard (T: tillage, T+FYM: tillage + farmyard manure, G: grass strips, G+NPK1: grass strips + rational rates of NPK, and G+NPK2: grass strips + higher rates of NPK) were tested in a temperate climate of Slovakia (Central Europe) under specific soil conditions (Rendzic Leptosol). We investigated the influence of continuous cropping on soil chemical properties and microbial communities during the dry and warm year of 2022. The results showed that the soil pH was higher by 19%, 21%, 24% and 13% in T, T+FYM, G and G+NPK1, respectively, compared to G+NPK2. The lowest soil organic matter (SOM) content was found in T, and it increased in the following order: T &lt; T+FYM &lt; G+NPK2 &lt; G+NPK1 &lt; G. Similarly, the lowest abundance of soil culturable bacteriota was found in T and it increased in the following order: T &lt; T+FYM = G+NPK2 &lt; G+NPK1&lt; G. Culturable bacteriota was identified using mass spectrometry (MALDI-TOF MS Biotyper). The most numerous species group was Bacillus, followed by Lactobacillus &gt; Staphylococcus &gt; Pseudomonas. The most frequently isolated species were Bacillus megaterium (16.55%), Bacillus cereus (5.80%), Bacillus thuringiensis (4.87%), and Bacillus simplex (4.37%). Positive relationships between SOM and soil culturable bacteriota were found in the G and G+NPK1 treatments. Temperature also affected soil culturable bacteriota in all soil management practices, most significantly in G+NPK1. Overall, the best scenario for the sustainable management of a productive vineyard is the use of grass strips.

Environmental Determinants of Islet Autoimmunity (ENDIA) longitudinal prospective pregnancy to childhood cohort study of Australian children at risk of type 1 diabetes: parental demographics and birth information.

The Environmental Determinants of Islet Autoimmunity (ENDIA) Study is an ongoing Australian prospective cohort study investigating how modifiable prenatal and early-life exposures drive the development of islet autoimmunity and type 1 diabetes (T1D) in children. In this profile, we describe the cohort's parental demographics, maternal and neonatal outcomes and human leukocyte antigen (HLA) genotypes. Inclusion criteria were an unborn child, or infant aged less than 6 months, with a first-degree relative (FDR) with T1D. The primary outcome was persistent islet autoimmunity, with children followed until a T1D diagnosis or 10 years of age. Demographic data were collected at enrollment. Lifestyle, clinical and anthropometric data were collected at each visit during pregnancy and clinical pregnancy and birth data were verified against medical case notes. Data were compared between mothers with and without T1D. HLA genotyping was performed on the ENDIA child and all available FDRs. The final cohort comprised 1473 infants born to 1214 gestational mothers across 1453 pregnancies, with 80% enrolled during pregnancy. The distribution of familial T1D probands was 62% maternal, 28% paternal and 11% sibling. The frequency of high-risk HLA genotypes was highest in T1D probands, followed by ENDIA infants, and lowest among unaffected family members. Mothers with T1D had higher rates of pregnancy complications and perinatal intervention, and larger babies of shorter gestation. Parent demographics were comparable to the Australian population for age, parity and obesity. A greater percentage of ENDIA parents were Australian born, lived in a major city and had higher socioeconomic advantage and education. This comprehensive profile provides the context for understanding ENDIA's scope, methodology, unique strengths and limitations. Now fully recruited, ENDIA will provide unique insights into the roles of early-life factors in the development of islet autoimmunity and T1D in the Australian environment. ACTRN12613000794707.

Risk Factors of Ischemic Heart Disease and Risk-Related Awareness in University Students

Objective: Ischemic heart disease (IHD) is the most fatal disease in Turkey. The present study attempted to explore IHD risk factors and risk-related awareness among university students. Materials and Methods: We took the height, weight, waist circumference, and blood pressure measurements of 786 university students and tried to identify their IHD risk factors and risk-related awareness through a survey. The study was carried out on a public university campus over three weekends in October 2022. Results: The findings showed that the most common modifiable IHD risk factors were poor physical activity (48.9%), smoking (30.5%), and overweight/obesity (21.5%) in our sample aged 18-35 years. Yet, the most prevalent non-modifiable risk factor was found to be familial chronic diseases (29.9%). Besides, the participants were found to have poor knowledge of IHD risk factors (8.9±2.5). Our other remarkable finding demonstrated that the male students’ knowledge of CVD was poorer than their female counterparts, although the male gender is a non-modifiable CVD risk factor. Conclusion: Participants with a relatively high level of education, interestingly, had poor knowledge and risk awareness of IHD despite bearing a higher rate of IHD risk factors.

Effect of lung volume preservation during spontaneous breathing trial on successful extubation in patients receiving mechanical ventilation: protocol for a multicenter clinical trial

BackgroundIn standard weaning from mechanical ventilation, a successful spontaneous breathing test (SBT) consisting of 30 min 8 cmH2O pressure-support ventilation (PSV8) without positive end-expiratory pressure (PEEP) is followed by extubation with continuous suctioning; however, these practices might promote derecruitment. Evidence supports the feasibility and safety of extubation without suctioning. Ultrasound can assess lung aeration and respiratory muscles. We hypothesize that weaning aiming to preserve lung volume can yield higher rates of successful extubation.MethodsThis multicenter superiority trial will randomly assign eligible patients to receive either standard weaning [SBT: 30-min PSV8 without PEEP followed by extubation with continuous suctioning] or lung-volume-preservation weaning [SBT: 30-min PSV8 + 5 cmH2O PEEP followed by extubation with positive pressure without suctioning]. We will compare the rates of successful extubation and reintubation, ICU and hospital stays, and ultrasound measurements of the volume of aerated lung (modified lung ultrasound score), diaphragm and intercostal muscle thickness, and thickening fraction before and after successful or failed SBT. Patients will be followed for 90 days after randomization.DiscussionWe aim to recruit a large sample of representative patients (N = 1600). Our study cannot elucidate the specific effects of PEEP during SBT and of positive pressure during extubation; the results will show the joint effects derived from the synergy of these two factors. Although universal ultrasound monitoring of lungs, diaphragm, and intercostal muscles throughout weaning is unfeasible, if derecruitment is a major cause of weaning failure, ultrasound may help clinicians decide about extubation in high-risk and borderline patients.Trial registrationThe Research Ethics Committee (CEIm) of the Fundació Unió Catalana d’Hospitals approved the study (CEI 22/67 and 23/26). Registered at ClinicalTrials.gov in August 2023. Identifier: NCT05526053.

Enhanced biosafety, anticancerand antibacterial photodynamic activities using silver-pyropheophorbide-a nanoconjugates.

Aim: A study of the enhancement of photodynamic activities of pyropheophorbide-a using PG-Ag-PPa nanoconjugates. Materials & methods: The nanoconjugates were formulated from silver nanoparticles and PPa via amide linkage, then characterized, and their photodynamic activities were examined. Results: The nanoconjugates displayed a higher rate of reactive oxygen species generation, commendable cellular uptake by Eca-109 cancer cells, higher photocytotoxicity toward the cancer cellsand better bio-safety. They revealed strong antibacterial activity against Escherichia coli following internal reactive oxygen species generation and membrane disintegration. The in vivo anticancer studies confirmed higher cytotoxicity of thenanoconjugatestoward cancer cells and better safety than PPa. Conclusion: Therefore, PG-Ag-PPa nanoconjugates could be considered potential nano photosensitizers for photodynamic therapy of tumors and bacterial infection with good bio-safety.

Outcomes and Performance Following Posteromedial Elbow Debridement in Major League Baseball Players

Overhead athletes are particularly susceptible to elbow valgus extension overload syndrome and development of pathologic changes in the posteromedial elbow. Though arthroscopic débridement/osteophyte resection is frequently performed, few studies have analyzed the outcomes of this procedure, and none have specifically addressed professional level athletes. We hypothesized that following posteromedial elbow débridement, Major League Baseball (MLB) pitchers would exhibit a higher rate of ulnar collateral ligament (UCL) reconstruction than baseline incidence in the existing literature, along with a decline in pitching performance. Using publicly accessible websites, MLB athletes undergoing posteromedial elbow débridement from 2007 to 2022 were identified. Demographic information, procedure details, return to play (RTP) information, return to the disabled/injured list (DL/IL), subsequent UCL reconstruction, and pitching statistics were analyzed. Pitching performance metrics included Earned Runs Average (ERA), Walks Plus Hits Per Innings Pitched (WHIP), innings pitched, and fastball velocity. A total of 39 MLB players, including 26 pitchers, were included. Within the first three seasons after surgery, 82.1% (n=32) of players returned to play at the MLB level at a mean time of 176.1 ± 69 days. Pitchers exhibited a return to play (RTP) rate of 76.9% (n=20) at 175.8 ± 16 days. A total of 38.5% (n=10) of pitchers returned to the DL/IL for elbow-related issues within three seasons. Subsequent UCL reconstruction was seen only in pitchers, with a frequency of 19.2% (n=5). No statistically significant differences between single season pre/postoperative pitching metrics were identified. A small but significant (p<0.05) decrease in fastball velocity (94.4 vs 92.84; p=0.02) was observed over a three-season comparison. Contrary to our hypothesis, this study demonstrates that posteromedial elbow débridement is a viable surgery in MLB athletes, with RTP rate of 82.1% and no increase in rate of UCL reconstruction. Furthermore, there was no significant difference in single season pre- and postoperative statistical pitching performance. However, over three years postoperatively, there was a 38.5% rate of return to the DL/IL for ongoing elbow ailment and a significant decrease in pitch velocity, raising some concern over the longevity of postoperative improvements.

Central Nervous System Prophylaxis Utilization in Patients With Newly Diagnosed Diffuse Large B-Cell Lymphoma Within a Large Community Health System.

The impact of central nervous system (CNS) prophylaxis in diffuse large B-cell lymphoma (DLBCL) is contentious. The CNS International Prognostic Index (IPI) calculator offers prognostic guidance in identifying those patients who may be at highest risk of disease progression or relapse to the CNS. However, it is unclear whether this tool has guided clinician decision-making in a real-world setting. Studies have suggested that CNS prophylaxis may not offer clinically significant benefit in terms of preventing CNS disease progression. Given this, we investigated the utilization of CNS prophylaxis within our own population and documentation of the CNS-IPI score. We retrospectively evaluated patients with newly diagnosed DLBCL between January 1, 2014, and December 31, 2017. Patients were assessed for receipt of CNS prophylaxis in the form of intrathecal (IT) chemotherapy and/or high-dose intravenous (IV) methotrexate. CNS-IPI scores were calculated for all patients who received CNS prophylaxis or those who experienced CNS disease. Long-term outcomes at five years from diagnosis included CNS progression/relapse and survival. Of 234 patients who met criteria, 20 (8.6%) received either IV methotrexate or IT chemotherapy; most received IT methotrexate. No patients in the IT prophylaxis group developed CNS disease, while two of eight IV methotrexate patients experienced CNS disease involvement. The incidence of CNS progression was 3.7% in the no prophylaxis group and 10% in those who received prophylaxis. This study revealed low utilization of CNS prophylaxis and CNS-IPI documentation in a community hospital system. Given large differences between groups, claims of CNS prophylaxis efficacy are unable to be made. CNS relapse rates were consistent with existing literature and promote continued evaluation of the utility of current CNS prophylaxis approaches in DLBCL. New unambiguously effective therapeutic approaches are needed and may encourage a higher rate of standardized use.

Medium-term outcomes after magnetic sphincter augmentation vs. fundoplication for reflux disease due to hiatal hernia: a propensity-score matched comparison in 282 patients.

An increasing number of reflux patients opt for magnetic sphincter augmentation (MSA) instead of fundoplication. However, few studies comparethe medium-term efficacy and safety of the procedures. We conducted a retrospective single-center analysis of consecutive MSA and Nissen fundoplication cases between 01/2015 and 06/2020. Patients underwent surgery, including hiatoplasty, for medical treatment-resistant reflux due to hiatal hernia. Surgical revision and proton pump inhibitor (PPI) reuptake rates were the primary outcomes. We also compared adverse event rates. Patients with severe preoperative dysphagia/motility disorders were assigned different treatment pathways and excluded from the analysis. We used propensity-score matching to reduce confounding between treatments. Out of 411 eligible patients, 141 patients who underwent MSA and 141 with fundoplication had similar propensity scores and were analyzed. On average, patients were 55 ± 12years old and overweight (BMI: 28 ± 5). At 3.9years of mean follow-up, MSA was associated with lower surgical revision risk as compared to fundoplication (1.2% vs 3.0% per year, respectively; HR: 0.38; 95% CI 0.15-0.96; p = 0.04), and similar PPI-reuptake risk (2.6% vs 4.2% per year; HR: 0.59; 95% CI 0.30-1.16; p = 0.12). Adverse event rates during primary stay were similar (MSA vs. fundoplication: 1% vs. 3%, p = 0.68). Fewer patients experienced adverse events in the MSA group after discharge (24% vs. 33%, p = 0.11), driven by higher rates of self-limiting dysphagia (1% vs. 9%, p < 0.01) and gas/bloating (10% vs. 18%, p = 0.06) after fundoplication. Differences between MSA and fundoplication in dysphagia requiring diagnostic endoscopy (11% vs. 8%, p = 0.54) or surgical revision (2% vs. 1%, p = 1.0) were non-significant. The device explantation rate was 4% (5/141). MSA reduces the re-operation risk compared to fundoplication and may decrease adverse event rates after discharge. Randomized head-to-head studies between available surgical options are needed.

ChatGPT vs Medical Professional: Analyzing Responses to Laboratory Medicine Questions on Social Media.

The integration of ChatGPT, a large language model (LLM) developed by OpenAI, into healthcare has sparked significant interest due to its potential to enhance patient care and medical education. With the increasing trend of patients accessing laboratory results online, there is a pressing need to evaluate the effectiveness of ChatGPT in providing accurate laboratory medicine information. Our study evaluates ChatGPT's effectiveness in addressing patient questions in this area, comparing its performance with that of medical professionals on social media. This study sourced patient questions and medical professional responses from Reddit and Quora, comparing them with responses generated by ChatGPT versions 3.5 and 4.0. Experienced laboratory medicine professionals evaluated the responses for quality and preference. Evaluation results were further analyzed using R software. The study analyzed 49 questions, with evaluators reviewing responses from both medical professionals and ChatGPT. ChatGPT's responses were preferred by 75.9% of evaluators and generally received higher ratings for quality. They were noted for their comprehensive and accurate information, whereas responses from medical professionals were valued for their conciseness. The interrater agreement was fair, indicating some subjectivity but a consistent preference for ChatGPT's detailed responses. ChatGPT demonstrates potential as an effective tool for addressing queries in laboratory medicine, often surpassing medical professionals in response quality. These results support the need for further research to confirm ChatGPT's utility and explore its integration into healthcare settings.
