Authors: Reynolds Christopher A. , Mehta Manish P. , Wu Scott , Neuville Alexander J. , Ho Alisha , Shah Chirag M. 
Published: February 2024

Background: Social media provides an increasingly popular, unfiltered source of perspectives on healthcare. The objective of this study is to characterize the landscape of social media posts regarding carpal tunnel release (CTR). Methods: Content was queried from Instagram between February 2, 2019 to August 12, 2021 using the hashtags #carpaltunnelrelease and #carpaltunnelsurgery. The 1500 most-liked posts were analyzed. Poster demographics including age, gender, region, and symptom qualities and post characteristics including type, number, timing relative to surgery, tone, and satisfaction were collected. Categorical variables were compared utilizing chi-squared test. Univariate and multivariate regression were performed. Results: The most popular post types included single photo (55.2%), multiple photos (18.8%), or single video (18.2%). Of all, 70.6% posts had fewer than 50 “likes.” Patients accounted for 51.8% of posts, followed by surgeons (13.3%), other health care providers (11.7%), and physical therapists (8.8%). Women (66.7%) outnumbered men (33.3%). Fifty-five percent of posts were domestic. Posts mostly depicted postoperative care (85.6%). The most frequently mentioned symptoms were pain, burning, numbness, and tingling. Of all posts, 45.1% had a positive tone, 49.1% neutral, and 5.7% negative. Univariate analysis revealed that posters who were patients, underwent open CTR, and were female were more likely to post negative sentiments. Conclusions: Most posts regarding CTR are from patients, are postoperative, and are positive or neutral. Although rare, negative posts were more likely to originate from posters who are patients, female, or underwent open CTR. With this information, surgeons will be better prepared to address patient concerns, set patient expectations, and enter the social media themselves.

Objectives: The objective of this study was to evaluate the effectiveness of a hydrogel spacer in reducing acute and delayed rectal toxicities. Materials and Methods: Patients undergoing definitive radiotherapy between January 2015 and March 2018 were retrospectively identified from our institutional cancer registry. Planning data were collected on dose-volume histograms (DVH) for V65, V70 and V75 Gy. All patients underwent definitive volumetric modulated arc therapy (VMAT) of 78 Gy over 39 fractions in a single centre. Toxicity reporting and definitions were in accordance with Common Terminology Criteria for Adverse Events (CTCAE) guidelines. Results: A total of 162 patients received radiotherapy during the study period (spacer n = 80; no spacer n = 82). Baseline characteristics between groups were comparable. Acute rectal toxicity was documented in 19 men (24%) with spacer versus 36 men (44%) without spacer devices ( p = 0.007). Over a median post-treatment follow-up period of 17 months (range = 3–38 months), there was a significant reduction in delayed toxicity in men with spacers compared to men without (17 men 21% vs. 31 men 39%, p = 0.021). Conclusion: Hydrogel spacer devices reduce rectal radiation exposure in prostate cancer patients undergoing radiotherapy. This translates into a clinical benefit in terms of acute and delayed rectal toxicities. Level of evidence: cohort study
Menopause and the role of physical activity – The views and knowledge of women aged 40–65
Authors: Wasley David , Gailey Samantha 
Published: February 2024

Menopause marks the end of female reproductive capacity. It is defined as the point after cessation of the menstrual cycle for 12 months (Nursat et al., 2008). Awareness about menopause has increased over the last decade, yet studies have shown that women still lack knowledge regarding the subject. Likewise, awareness of women between the age of 40–65 on the potential role of physical activity prior to and during menopause in women is unclear. Women ( n = 162) aged 40–65 years completed a survey rating their knowledge, answered fact-based questions and reported their experiences of menopause. Their levels of, and beliefs on, the role physical activity on symptoms and menopause associated disease risk were also collected. Women reported their confidence in their current knowledge level at 67% reflecting 37% higher rating than an estimate of their knowledge 10 years ago. Their factual knowledge score was 56%. Knowledge was primarily gained through friends and family and almost half (46%) had not spoken to a healthcare professional. Frustration was expressed with lack of knowledge and support of healthcare and others. Women using HRT (44%) had mixed attitudes towards its role. A high proportion were active and felt that physical activity can help manage symptoms and impact long-term health consequences of menopause. Menopause education strategies for women, healthcare professionals and others need to be improved. Lack of education may be causing women to struggle and feel negatively towards this life stage. Physical activity was viewed positively for the symptoms and a treatment during menopause and long-term health.
Comparing Spinal Cord Drift, Clinical Outcomes and C5 Palsy in Degenerative Cervical Myelopathy: A Study of Cervical Laminoplasty Versus Laminectomy/Fusion
Authors: Basu Saumyajit , Gohil Kushal 
Published: February 2024

Study design Retrospective comparative study. Objectives (i)to compare spinal cord drift between laminectomy and fusion(LF) and cervical laminoplasty(LP) for degenerative cervical myelopathy(DCM) treatment,(ii)to study relationship between preoperative cervical alignment, postoperative spinal cord drift, functional outcome, and C5 palsy. Methods A cohort of 114 patients who underwent LP or LF for DCM were identified. After propensity-score matching, both groups included 30 patients each.Cobb angle(C2-C7) was used to assess pre-and postoperative cervical spine alignment(at 2-year follow-up).Based on alignment, there were lordotic(L) and straight(S) subgroups.Spinal cord position was measured on sagittal-and axial-T2W MRI of cervical spine pre-and postoperatively at 2-year follow-up and cord drift was measured by subtracting preoperative values from postoperative values.Functional recovery(mJOA score, mJOA recovery rate),and C5 palsy in patients were recorded and compared. Results LF had higher mean spinal cord drift than LP(2.66 ± .77 vs 2.16 ± .80 mm, P = .049).Lordotic subgroups exhibited greater cord drift than straight subgroups within LP and LF groups.Both groups significantly improved mJOA scores at 2-year follow-up, with no LP-LF difference in mJOA recovery rate(mJOA-RR).Lordotic subgroups had significantly higher mJOA-RR(LP-L vs LP-S, P = .048; LF-L vs LF-S, P = .045).Preoperative cervical alignment, cord drift, and mJOA-RR correlated well(Spearman’s ρ .7143 and .6053 respectively).Patients with >2.5 mm cord drift(n = 24) had significantly higher mJOA-RR as compared to <2.5 mm cord drift(n = 18). Substantial clinical difference was seen in C5 palsy risk between LP-S and LF-L, with the LF-L group having 3-fold higher risk. Conclusion LF had a biomechanical advantage in maximizing spinal cord drift in severe DCM cases, while both LP and LF showed significant improvements in neurological function. However, variability in C5 palsy rates highlights the need for individualized patient assessment.

Abstract
Treatment resistance of leukemia stem cells (LSCs) and suppression of the autologous immune system represent major challenges to achieve a cure in acute myeloid leukemia (AML). Although AML blasts generally retain high levels of surface CD38 (CD38pos), LSCs are frequently enriched in the CD34posCD38neg blast fraction. Here, we report that interferon gamma (IFN-γ) reduces LSCs clonogenic activity and induces CD38 upregulation in both CD38pos and CD38neg LSC-enriched blasts. IFN-γ–induced CD38 upregulation depends on interferon regulatory factor 1 transcriptional activation of the CD38 promoter. To leverage this observation, we created a novel compact, single-chain CD38-CD3 T-cell engager (BN-CD38) designed to promote an effective immunological synapse between CD38pos AML cells and both CD8pos and CD4pos T cells. We demonstrate that BN-CD38 engages autologous CD4pos and CD8pos T cells and CD38pos AML blasts, leading to T-cell activation and expansion and to the elimination of leukemia cells in an autologous setting. Importantly, BN-CD38 engagement induces the release of high levels of IFN-γ, driving the expression of CD38 on CD34posCD38neg LSC-enriched blasts and their subsequent elimination. Critically, although BN-CD38 showed significant in vivo efficacy across multiple disseminated AML cell lines and patient-derived xenograft models, it did not affect normal hematopoietic stem cell clonogenicity and the development of multilineage human immune cells in CD34pos humanized mice. Taken together, this study provides important insights to target and eliminate AML LSCs.
WSB1, as an E3 ligase, restrains myocardial ischemia–reperfusion injury by activating β-catenin signaling via promoting GSK3β ubiquitination
Authors: Fang Lini , Tao Yang , Che Guoying , Yun Yongzi , Ren Min , Liu Yujie 
Published: February 2024

Abstract
Background
Reperfusion is the most effective strategy for myocardial infarct, but induces additional injury. WD repeat and SOCS box containing protein 1 (WSB1) plays a protective role in ischemic cells. This study aims to investigate the effects of WSB1 on myocardial ischemia–reperfusion (IR) injury.

Methods
The myocardial IR was induced by left anterior descending (LAD) ligation for 45 min and subsequent reperfusion. The overexpression of WSB1 was mediated by tail vein injection of AAV9 loaded with WSB1 encoding sequence two weeks before IR surgery. H9c2 myocardial cells underwent oxygen-sugar deprivation/reperfusion (OGD/R) to mimic IR, and transfected with WSB1 overexpression or silencing plasmid to alter the expression of WSB1.

Results
WSB1 was found highly expressed in penumbra of myocardial IR rats, and the WSB1 overexpression relieved IR-induced cardio dysfunction, myocardial infarct and pathological damage, and cardiomyocyte death in penumbra. The ectopic expression of WSB1 in H9c2 myocardial cells mitigated OGD/R-caused apoptosis, and silencing of WSB1 exacerbated the apoptosis. In addition, WSB1 activated β-catenin signaling, which was deactivated under the ischemic condition. The co-immunoprecipitation results revealed that WSB1 mediated ubiquitination and degradation of glycogen synthase kinase 3 beta (GSK3β) as an E3 ligase in myocardial cells. The effects of WSB1 on myocardial cells under ischemic conditions were abolished by an inhibitor of β-catenin signaling.

Conclusion
WSB1 activated β-catenin pathway by promoting the ubiquitination of GSK3β, and restrained IR-induced myocardial injury. These findings might provide novel insights for clinical treatment of myocardial ischemic patients.
Alternative blood transfusion triggers: a narrative review
Authors: Arynov Ardak , Kaidarova Dilyara , Kabon Barbara 
Published: February 2024

Abstract
Background
Anemia, characterized by low hemoglobin levels, is a global public health concern. Anemia is an independent factor worsening outcomes in various patient groups. Blood transfusion has been the traditional treatment for anemia; its triggers, primarily based on hemoglobin levels; however, hemoglobin level is not always an ideal trigger for blood transfusion. Additionally, blood transfusion worsens clinical outcomes in certain patient groups. This narrative review explores alternative triggers for red blood cell transfusion and their physiological basis.

Main Text
The review delves into the physiology of oxygen transport and highlights the limitations of using hemoglobin levels alone as transfusion trigger. The main aim of blood transfusion is to optimize oxygen delivery, necessitating an individualized approach based on clinical signs of anemia and the balance between oxygen delivery and consumption, reflected by the oxygen extraction rate. The narrative review covers different alternative triggers. It presents insights into their diagnostic value and clinical applications, emphasizing the need for personalized transfusion strategies.

Conclusion
Anemia and blood transfusion are significant factors affecting patient outcomes. While restrictive transfusion strategies are widely recommended, they may not account for the nuances of specific patient populations. The search for alternative transfusion triggers is essential to tailor transfusion therapy effectively, especially in patients with comorbidities or unique clinical profiles. Investigating alternative triggers not only enhances patient care by identifying more precise indicators but also minimizes transfusion-related risks, optimizes blood product utilization, and ensures availability when needed. Personalized transfusion strategies based on alternative triggers hold the potential to improve outcomes in various clinical scenarios, addressing anemia’s complex challenges in healthcare. Further research and evidence are needed to refine these alternative triggers and guide their implementation in clinical practice.
The role of dexmedetomidine administered via intravenous infusion as adjunctive therapy to mitigate postoperative delirium and postoperative cognitive dysfunction in elderly patients undergoing regional anesthesia: a meta-analysis of randomized controlled trials
Authors: Wang Di , He Xiao , Li Zicen , Tao He , Bi Congjie 
Published: February 2024

Abstract
Study objective
This meta-analysis aimed to assess whether continuous intravenous administration of DEX during surgery can be part of the measures to prevent the onset of postoperative delirium and postoperative cognitive dysfunction in elderly individuals following regional anesthesia.

Methods
We searched the databases of PubMed, Embase, the Cochrane Library and China National Knowledge Infrastructure (by June 1, 2023) for all available randomized controlled trials assessing whether intravenous application of dexmedetomidine can help with postoperative delirium and postoperative cognitive dysfunction in the elderly with regional anesthesia. Subsequently, we carried out statistical analysis and graphing using Review Manager software (RevMan version 5.4.1) and STATA software (Version 12.0).

Main results
Within the scope of this meta-analysis, a total of 18 randomized controlled trials were included. Among them, 10 trials aimed to assess the incidence of postoperative delirium as the primary outcome, while the primary focus of the other 8 trials was on the incidence of postoperative cognitive dysfunction. The collective evidence from these 10 studies consistently supports a positive relationship between the intravenous administration of dexmedetomidine and a decreased risk of postoperative delirium (RR: 0.48; 95%CI: 0.37 to 0.63, p < 0.00001, I2 = 0%). The 8 literature articles and experiments evaluating postoperative cognitive dysfunction showed that continuous intravenous infusion of dexmedetomidine during the entire surgical procedure exhibited a positive preventive effect on cognitive dysfunction among the elderly population with no obvious heterogeneity (RR: 0.35; 95%CI: 0.25 to 0.49,p < 0.00001, I2 = 0%).

Conclusion
Administering dexmedetomidine intravenously during surgery can potentially play a significant role in preventing postoperative delirium and postoperative cognitive dysfunction in patients older than 60 years with regional anesthesia according to this meta-analysis.

Published: February 2024

Abstract
Background
Frailty is a common geriatric syndrome related to multiple adverse outcomes. Sex differences in its prevalence and impact on mortality remain incompletely understood.

Methods
This study was conducted with data from the I-Lan Longitudinal Aging Study, in which community-dwelling subjects aged > 50 years without coronary artery disease or diabetes were enrolled. Sex disparities in phenotypically defined frailty and sex–morality predictor interactions were evaluated. Sex- and frailty-stratified analyses of mortality were performed.

Results
The sample comprised 1371 subjects (51.4% women, median age 61 years). The median follow-up period was 6.3 (interquartile range, 5.8–7.0) years. The frailty prevalence did not differ between men (5.3%) and women (5.8%). Frail individuals were older and less educated and had poorer renal function than did non-frail individuals. Body composition trends differed between sexes, regardless of frailty. Relative to non-frail men, frail men had significantly lower body mass indices (BMIs; 24.5 vs. 23.4 kg/m2, p = 0.04) and relative appendicular skeletal muscle masses (7.87 vs. 7.05 kg/m2, p < 0.001). Frail women had significantly higher BMIs (25.2 vs. 23.9 kg/m2, p = 0.02) and waist circumferences (88 vs. 80 cm, p < 0.001) than did non-frail women. Frailty was an independent mortality predictor for men only [hazard ratio (95% confidence interval) = 3.395 (1.809–6.371), psex–frailty interaction = 0.03].

Conclusion
Frailty reflected poorer health in men than in women in the present cohort. This study revealed sex disparities in the impact of frailty on mortality among relatively healthy community-dwelling older adults.
Blood neutrophil to lymphocyte ratio is associated with 90-day mortality and 60-day readmission in Gram negative bacteremia: a multi-center cohort study
Authors: Roldgaard Marcus , Benfield Thomas , Tingsgård Sandra 
Published: February 2024

Abstract
Introduction
The Neutrophil-Lymphocyte Ratio (NLR) in blood has demonstrated its capability to predict bacteremia in emergency departments, and its association with mortality has been established in patients with sepsis in intensive care units. However, its potential concerning mortality and readmission in patients with Gram-negative bacteremia (GNB) is unexplored.

Methods
This retrospective cohort study included patients with GNB between 2018 and 2022 from six hospitals in the Capital Region of Denmark. Patients who were immunosuppressed or had missing NLR values on the day of blood culture were excluded. Logistic regression models were used to analyze the association between NLR levels and 90-day all-cause mortality, while the logit link interpretation of the cumulative incidence function was used to assess the association between NLR levels and 60-day readmission. Associations were quantified as odds ratios (OR) with corresponding 95% confidence intervals (CI).

Results
The study included 1763 patients with a median age was 76.8 years and 51.3% were female. The median NLR was 17.3 and 15.8% of patients had a quick sequential organ failure assessment score of two or three. Urinary tract infection (UTI) was the most frequent focus and Escherichia coli the most frequent pathogen. Statistically significant differences in median NLR were found by age group and pathogen, and for patients with or without hypertension, liver disease, chronic obstructive pulmonary disease, dementia, and alcohol abuse. 378 patients (21.4%) died before 90 days. 526 (29.8%) patients were readmitted to the hospital within 60 days. For each doubling of the NLR, the OR for all-cause 90-day mortality was 1.15 (95% CI, 1.04–1.27) and 1.12 (95% CI, 1.02–1.24) for 60-day readmission. Analysis of subgroups did not show statistically significant differences between groups in relation to the association between NLR and mortality. The discriminatory ability of NLR for mortality was limited and comparable to blood neutrophil or lymphocyte count, producing receiver operating characteristic curves with an area under the curve of 0.59 (95% CI, 0.56–0.63), 0.60 (95% CI, 0.56–0.65) and 0.53 (95% CI, 0.49–0.56), respectively.

Conclusion
Blood neutrophil-lymphocyte ratio was associated with 90-day all-cause mortality and 60-day readmission in patients with GNB. However, the ratio has limited ability in predicting mortality or readmission.
Assessing the effects of tempol on renal fibrosis, inflammation, and oxidative stress in a high-salt diet combined with 5/6 nephrectomy rat model: utilizing oxidized albumin as a biomarker
Authors: Liu Beibei , Hu Yanling , Tian Danyang , Dong Jianlong , Li Bing-Feng 
Published: February 2024

Abstract
Background
Oxidative stress has been implicated in the pathogenesis of chronic kidney disease (CKD), prompting the exploration of antioxidants as a potential therapeutic avenue for mitigating disease progression. This study aims to investigate the beneficial impact of Tempol on the progression of CKD in a rat model utilizing oxidized albumin as a biomarker.

Methods
After four weeks of treatment, metabolic parameters, including body weight, left ventricle residual weight, kidney weight, urine volume, and water and food intake, were measured. Systolic blood pressure, urinary protein, oxidized albumin level, serum creatinine (Scr), blood urea nitrogen (BUN), 8-OHdG, TGF-β1, and micro-albumin were also assessed. Renal fibrosis was evaluated through histological and biochemical assays. P65-NF-κB was quantified using an immunofluorescence test, while Smad3, P65-NF-κB, and Collagen I were measured using western blot. TNF-α, IL-6, MCP-1, TGF-β1, Smad3, and P65-NF-κB were analyzed by RT-qPCR.

Results
Rats in the high-salt diet group exhibited impaired renal function, characterized by elevated levels of blood urea nitrogen, serum creatinine, 8-OHdG, urine albumin, and tubulointerstitial damage, along with reduced body weight. However, these effects were significantly ameliorated by Tempol administration. In the high-salt diet group, blood pressure, urinary protein, and oxidized albumin levels were notably higher compared to the normal diet group, but Tempol administration in the treatment group reversed these effects. Rats in the high-salt diet group also displayed increased levels of proinflammatory factors (TNF-α, IL-6, MCP1) and profibrotic factors (NF-κB activation, Collagen I), elevated expression of NADPH oxidation-related subunits (P65), and activation of the TGF-β1/Smad3 signaling pathway. Tempol treatment inhibited NF-κB-mediated inflammation and TGF-β1/Smad3-induced renal fibrosis signaling pathway activation.

Conclusion
These findings suggest that Tempol may hold therapeutic potential for preventing and treating rats undergoing 5/6 nephrectomy. Further research is warranted to elucidate the mechanisms underlying Tempol’s protective effects and its potential clinical applications. Besides, there is a discernible positive relationship between oxidized albumin and other biomarkers, such as 8-OHG, urinary protein levels, mALB, Scr, BUN, and TGF-β1 in a High-salt diet combined with 5/6 nephrectomy rat model. These findings suggest the potential utility of oxidized albumin as a sensitive indicator for oxidative stress assessment.
