Authors: Hu Jianhua , Jin Qun , Fang Honglong , Zhang Weiwen
Published: April 2024

Sepsis remains a significant clinical challenge owing to its complex pathophysiology and variable prognosis. The early identification of patients at a higher risk of poor outcomes can be crucial for improving treatment strategies. This study aimed to evaluate the predictive value of early serum lactate and albumin levels and the lactate/albumin (L/A) ratio for 28-day prognosis in patients with sepsis. Patients diagnosed with sepsis between January 2021 and December 2022 were evaluated using a retrospective cohort methodology. Inclusion followed the International Consensus on sepsis and septic shock (Sepsis-3) guidelines and patients were selected based on well-defined criteria. Variables such as lactate, albumin, and the L/A ratio were documented within the first 24 hours of admission. Statistical analyses were performed using various tools, including the nonparametric Mann–Whitney U test and receiver operating characteristic curves. A total of 301 patients were divided into the survival (n = 167) and death (n = 134) groups. Notable differences were detected in the incidence of pulmonary infection, shock, lactate, albumin, and the L/A ratio. The L/A ratio was identified as a key predictor with an area under the curve of 0.868, an optimal cutoff value of >0.17, a sensitivity of 56.21%, and a specificity of 94.18%. Significant disparities in mortality rates and survival times were observed for the lactate, albumin, and L/A levels. This study underscores the predictive value of early serum lactate and albumin levels and the L/A ratio for 28-day prognosis in patients with sepsis, with the L/A ratio showing a superior predictive capability. These findings highlight the importance of L/A ratio as a robust and precise marker for evaluating the future clinical course of patients with sepsis, potentially aiding early detection and management.

Published: April 2024

In the elderly population, Parkinson’s Disease (PD) is the second most common neurodegenerative disorder and is associated with morphological changes in the basal ganglia, especially the substantia nigra (SN). This study aimed to evaluate the volume and signal intensity (SI) of SN using Magnetic Resonance Imaging (MRI) to detect structural changes and investigate the relationship between the onset side and disease severity of PD. Clinical features and imaging data of 58 patients with PD were retrospectively analyzed from their medical records. Axial T2-weighted fluid-attenuated inversion recovery (FLAIR) sequences of 3 Tesla (T) MRIs were used for the measurements. The right and left SN volumes and SI measurements were calculated in duplicate by 2 blinded and qualified neuroradiologists. The side of disease onset, disease duration, levodopa equivalent daily dose, Movement Disorder Society-sponsored Unified Parkinson Disease Rating Scale (MDS-UPDRS III) motor score, and modified Hoehn and Yahr (H&Y) scale scores were recorded and compared with SN volume and SI measurements. No statistically significant difference was found between the disease onset side and contralateral SN volume or SI measurements (P > .05). Despite high inter- and intra-rater reliability rates, there was no significant difference in the volume and SI of the contralateral SN according to H&Y stages (P > .05). Furthermore, SN volume and SI measurements were not significantly correlated with disease duration and MDS-UPDRS III motor score (P > .05). SN volume and SI values measured using axial FLAIR 3T MRI are not correlated with the side of onset or disease severity in PD. New imaging methods are required to detect preclinical or early-stage PD.

Published: April 2024

Thyroid dysfunction is associated with the risk of cardiovascular disease; however, whether plasma thyroid-stimulating hormone (TSH) levels in subjects with euthyroidism affect the risk of cardiovascular disease remains unclear. This study aimed to investigate the causal association between plasma TSH levels and cardiovascular diseases, particularly ischemic heart disease and heart failure (HF). Summary statistics from the Integrative Epidemiology Unit Open genome-wide association studies Project and FinnGen consortium were used to investigate the causal relationship between plasma TSH levels and the risk of cardiovascular diseases. Two-sample Mendelian randomization analysis using inverse-variance weighting as the primary method was performed. The MR Pleiotropy RESidual Sum and Outlier and leave-one-out methods were used to ensure the robustness of our findings. Genetically determined plasma TSH levels were associated with major coronary heart disease events (OR 1.0557, 95% CI 1.0141–1.0991), all-cause HF (OR 0.9587, 95% CI 0.9231–0.9956), and HF + non-ischemic cardiomyopathy (OR 0.9318, 95% CI 0.8786–0.9882). After the Bonferroni correction, the causation described above disappeared. In the secondary analysis, genetically determined higher TSH levels were associated with a higher risk for unstable angina pectoris (OR 1.0913, 95% CI 1.0350–1.1507), but were associated with a lower risk for HF + overweight (OR 0.9265, 95% CI 0.8821–0.9731). These results were further validated using sensitivity analysis. Our findings show that increased plasma TSH levels in patients with euthyroidism may increase the risk of unstable angina pectoris but reduce the risk of HF in overweight patients. This evidence indicates that plasma TSH levels may need to be carefully controlled in specific patients.

Published: April 2024

Child abuse, by definition parents and other family members, caregivers, or any adult he does not know culturally inappropriate, harmful to the child described, inhibiting growth and development, or exposure to a restrictive behavior. This study aims to evaluate the capabilities of pediatricians and pedodontists in identifying and managing child abuse and neglect within healthcare settings, a crucial responsibility for professionals across various medical disciplines. Questionnaire was performed on 53 pediatricians and 89 pedodontists. Utilizing a 28-item expert-designed electronic questionnaire, the study solicited responses from pediatricians and pedodontists to assess their demographic characteristics, professional experience, and self-perceived competence in this critical area. The results indicate that 42% of the participating healthcare providers have encountered at least one case of child abuse and neglect. Notably, pedodontists displayed a higher level of uncertainty in identifying abuse and neglect cases compared to pediatricians. Furthermore, participants who had a higher level of self-perceived competence were significantly more willing to identify and manage cases, although this self-assessment did not correlate with their actual skills or level of willingness to intervene effectively. The study concludes that there is a pressing need for specialized training programs tailored to enhance the skill sets of healthcare providers in identifying and managing child abuse and neglect. These programs should encompass not only academic knowledge but also practical applications and psychosocial support techniques to ensure a holistic approach to combating this serious issue.

Authors: Saleh Mustafa , Raffoul Peter , Akil Alvar , Bassil Paul , Salameh Pascale
Published: April 2024

Background:

Bladder Cancer (BC) is a widespread form of cancer that affects over 1.6 million people globally. The majority of cases are diagnosed as urothelial carcinoma, with a higher likelihood of diagnosis in men and with increasing age. The Arab world (AW) is one of the regions with the highest incidence and mortality rates of BC, and the average age of diagnosis is between 40 and 49 years in North Africa and the Middle East. This study aims to assess the activity and distribution of BC publications in the AW.

Methods:

A systematic search across MEDLINE and Embase databases spanning 2007 to 2021 identified 1208 English-language articles on bladder cancer with Arab affiliations. The dataset was normalized against the average population and GDP (2007–2020) for 22 Arab countries. Statistical analyses via SPSS and visualizations with VOSviewer unveiled collaboration patterns and thematic trends in Arab bladder cancer research.

Results:

A total of 1208 BC publications were published in the AW, representing 0.24% of all biomedical publications. Egypt topped the list with the highest number of publications. The co-authorship analysis generated by VOSviewer revealed that out of 4766 authors, 161 met the minimum threshold of 5 publications.

Conclusion:

The findings reveal that Egypt and Jordan are at the forefront of BC research in the region, while other Arab countries are lagging behind despite being heavily impacted by the disease. To drive progress in the field, it’s important to uncover the obstacles impeding BC research in these countries and implement effective solutions to overcome them.

Published: April 2024

Adequate sleep is crucial for individuals’ well-being and cognitive functioning. However, medical students face unique challenges that disrupt their sleep patterns, such as a rigorous curriculum, long study hours, and high-stress levels. Understanding the sleep patterns and quality among medical students in Nigeria is important to develop targeted interventions and support their overall well-being. This study involved 802 medical students from 3 medical schools in Southwest Nigeria. Participants completed an online questionnaire that collected data on their demographic characteristics, sleep patterns and self-reported sleep quality. Descriptive statistics and correlation analysis were used to analyze the data and identify patterns and associations. Most participants were female (56.9%), with the highest representation from the UNILORIN (65.5%). The average reported sleep duration was 5.74 hours per night, indicating insufficient sleep. Irregular bedtimes and wake-up times were commonly reported. A significant proportion of students consumed coffee late at night (27.1%) and used medication to induce sleep (24.3%). Sleep patterns and behaviors, such as snoring (36.1%) and nocturnal eating (57.6%), were reported. Overall, participants reported satisfactory (28.3%) or poor (29.7%) sleep quality. Correlation analysis revealed significant associations between sleep patterns, sleep quality, academic performance, and other sleep-related factors. The study identified insufficient sleep duration, irregular bedtimes, late-night coffee consumption, and poor sleep quality. These findings emphasize the need for interventions and strategies to promote healthy sleep habits among medical students, which can positively impact their overall health and academic performance.
Primary adrenal lymphoma presenting as neurolymphomatosis: A case report
Authors: Chen Zhong , Lin Liyan , Xu Liqun , Lin Renhe , Jiang Xiaoling
Published: April 2024

Rationale:

Primary adrenal lymphoma (PAL) is a very rare and highly aggressive disease. Neurolymphomatosis (NL) is a rare manifestation of lymphoma characterized by the infiltration of lymphoma cells into peripheral nerves, resulting in neurological symptoms. To date, there have been very few reported cases of PAL with NL. By reviewing the entire treatment process of the patient, we aim to enhance recognition of PAL complicated with NL and guide clinicians to pay attention to the diagnosis of such diseases. Early recognition and diagnosis of NL are crucial for appropriate management and treatment decisions.

Patient concerns:

We report a case of PAL in a 64-year-old female whose initial symptoms were pain and weakness in the left leg, which progressively worsened. In the half month before admission, the patient also showed signs of cranial nerve damage, such as diplopia and facial asymmetry.

Diagnosis:

Computed tomography of the abdomen revealed an occupying lesion in the left adrenal region. Electromyography and somatosensory evoked potential examination of the extremities suggested left lumbar plexus damage and complete damage to the right facial nerve. Adrenal biopsy confirmed diffuse large B-cell lymphoma.

Interventions:

The patient was treated with the R-CHOP scheme (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) combined with lenalidomide.

Outcome:

After 6 rounds of chemotherapy, the symptoms improved slightly. However, the condition progressed, and the patient passed away 1 year later.

Lessons:

Due to the nonspecific clinical presentation, patients with neurological damage should be alerted to the possibility of PAL and need to be evaluated thoroughly.

Published: April 2024

Background:

Tic disorder is a common neurodevelopmental disorder in childhood, characterized primarily by motor or vocal tics. However, there is no systematic evaluation of pediatric massage therapy for children with Tic disorder. This study aims to evaluate the effectiveness and safety of massage therapy for children with tic disorder through a comprehensive meta-analysis and systematic review.

Methods:

We systematically searched relevant randomized controlled trials from various databases such as CBM, CNKI, VIP, Wanfang database, PubMed, Embase, Web of Science, Cochrane Library, and SINOMED, published up to October 2023. To collect randomized controlled trials on pediatric massage therapy or in combination with other therapies for the treatment of tic disorders in children. The risk of bias in the included articles was assessed using the Cochrane guideline. Meta-analyses were performed using Review Manager 5.4, and publication bias was evaluated by using Begg test and Egger test in Stata SE software.

Results:

This meta-analysis included 19 randomized controlled trials with 1423 patients. Pediatric massage therapy alone or in combination with conventional medication demonstrated a significant increase in clinical effectiveness rates [risk ratios = 1.15, 95% confidence interval [CI] (1.10, 1.20), Z = 6.54, P < .001], and reduced Yale Global Tie Severity Scale scores [standardized mean difference = −0.85, 95% CI (−1.50, −0.19), Z = 2.54, P = .01] and traditional Chinese medicine syndrome scores [standardized mean difference = −1.35, 95%CI (−2.08, −0.63), Z = 3.66, P = .0002]. In terms of adverse reactions, there was no statistical difference between the experimental and control groups [risk ratios = 0.26, 95% CI (0.14, 0.49), Z = 4.25, P < .001]. The Begg test and Egger test results indicated no publication bias.

Conclusion:

Evidence suggests that pediatric massage therapy is effective in improving tic disorders in children.
Platelet index ratios in HIV: Emerging biomarkers for immune health and disease management
Authors: Obeagu Emmanuel Ifeanyi , Obeagu Getrude Uzoma
Published: April 2024

Human Immunodeficiency Virus (HIV) infection is a global health challenge that requires continuous advancements in diagnostic and prognostic tools. Traditional markers, such as CD4 cell counts and viral load, have played a crucial role in monitoring disease progression and guiding therapeutic interventions. However, emerging research suggests that platelet index ratios may serve as valuable biomarkers in assessing immune health and managing HIV-associated complications. This paper explores the significance of platelet index ratios, including platelet-to-lymphocyte ratio and mean platelet volume-to-lymphocyte ratio, as potential indicators of immune system status in individuals living with HIV. The interplay between platelets, lymphocytes, and their ratios reflects the dynamic nature of the immune response and inflammatory processes during HIV infection. Understanding the role of platelet index ratios in HIV could lead to the development of accessible and cost-effective biomarkers for monitoring immune health. Implementation of these ratios in routine clinical practice may enhance the precision of disease prognosis and guide personalized treatment strategies. Additionally, the exploration of platelet index ratios may pave the way for innovative therapeutic interventions aimed at modulating immune responses in HIV-infected individuals. In conclusion, platelet index ratios represent promising emerging biomarkers for evaluating immune health and managing HIV-related complications. Further research and clinical validation are warranted to establish the utility of these ratios in routine HIV care, potentially revolutionizing the approach to monitoring and improving the health outcomes of individuals living with HIV.
Neutrophil-to-lymphocyte ratio on admission predicts early perihematomal edema growth after intracerebral hemorrhage
Authors: Mao Yirong , Huang Lumao , Ji Gengsheng , Wang Liang , Wang Xiang , Zheng Xinyi
Published: April 2024

Poor functional outcome is associated with perihematomal edema (PHE) expansion after intracerebral hemorrhage (ICH). The inflammatory response is crucial for the onset and progression of PHE. This study aimed to determine the connection between admission neutrophil-lymphocyte ratio (NLR) and early PHE development. We retrospectively analyzed patients with ICH admitted to the Chaohu Affiliated Hospital of Anhui Medical University from January 2021 to December 2022. The primary outcome measure was absolute PHE, defined as the volume of the follow-up PHE minus admission PHE. A semiautomated measurement tool (3D Slicer) was used to calculate the volumes of cerebral hematoma and cerebral edema. Spearman’s correlation analysis determined the relationship between NLR and absolute PHE. The multiple linear regression model was constructed to analyze the predictive relation of admission NLR on early PHE expansion. A total of 117 patients were included. The median hematoma and PHE volumes on admission were 9.38 mL (interquartile range [IQR], 4.53–19.54) and 3.54 mL (IQR, 1.33–7.1), respectively. The median absolute PHE was 2.26 mL (IQR, 1.25–4.23), and the median NLR was 3.10 (IQR, 2.26–3.86). Spearman’s correlation test showed a positive correlation between admission NLR and absolute PHE (r = .548, P < .001). Multiple linear regression analyses suggested that for every 1-unit increase in admission NLR (B = .176, SE = .043, Beta = .275, P < .001), there was a 0.176 mL increase in absolute PHE. Admission neutrophil-to-lymphocyte ratio (NLR) significantly and positively predicted early perihematomal edema (PHE) expansion.

Published: April 2024

Bronchial asthma (BA) is a chronic respiratory disease closely related to immune system dysregulation. Traditional Chinese medicine has long adopted the strategy of Sanao decoction in the treatment of bronchial asthma. However, due to the multi-target and multi-pathway characteristics of Chinese herbal medicine, we are still unclear about the specific mechanism of Sanao decoction in treating bronchial asthma. To investigate the mechanism of action of Sanao decoction in the treatment of BA using a network pharmacology approach and preliminary validation by molecular docking technology. Traditional Chinese medicine systems pharmacology database and analysis platform and UniProt databases were used to search the active ingredients and targets of Sanao decoction, and BA-related targets were screened according to GeneCards and online Mendelian inheritance in man database databases. The intersection targets were imported into the STRING database to construct a protein–protein interaction network, and Cytoscape 3.9.1 software was used to screen out hub genes. This study also constructed a “drug-ingredient-target” visual network diagram. Gene Ontology and Kyoto Encyclopedia of Genomes enrichment analysis was performed on targets in the protein–protein interaction network using the ClusterProfiler package in R, with a P value < .05. Autodock software was used for molecular docking to complete the preliminary verification of core components and targets. A total of 73 active compounds and 308 targets of Sanao decoction, including 1640 BA-related disease targets, were retrieved from mainstream databases. Gene Ontology analysis and Kyoto encyclopedia of genes and genomes enrichment analysis suggested that Sanao decoction plays a role in the treatment of BA through signaling pathways such as PI3K-Akt, MAPK, and IL-17 signaling pathway. The 9 core goals represent the main elements related to Sanao decoction in the treatment of BA. Subsequently, the molecular docking results showed that most of the active compounds of Sanao decoction have strong binding efficiency with the hub gene. Sanao decoction has a key impact on BA through multiple channels. In summary, this intricate network reflects the potential of Sanao decoction in treating BA, a multifactorial disease. In addition, this study laid the foundation for further in vivo and in vitro experimental research and expanded the clinical application of Sanao decoction.

Published: April 2024

Although Western Medicine is considered as the mainstream medicine in China, Traditional Chinese Medicine (TCM) still has its own advantages and characteristics. The attitudes and behaviors to TCM are divided, some West Medicine Doctors prefer TCM during treatment, while others consider it not effective. The objective of this study is to find out the attitudes and treatment behaviors of Chengdu physicians toward TCM, and identify factors associated with their attitude and behaviors. A representative sample of 2049 Chengdu physicians were recruited online to investigate their attitudes and behaviors toward TCM. During this research, previous Integrative Medicine Attitude Questionnaire were referred and modified, and adjusted questionnaire was made based on the actual situation of TCM in Chengdu. This questionnaire contains 3 distinct parts. The first part aimed at the attitudes of respondents toward TCM, and contains 15 questions in 3 sections, Holism, Knowledge, and Evidence. The second part tried to determine the behaviors toward TCM in terms of self-use, recommendations, as well as prescriptions. In addition, 6 modalities including Chinese Patent Medicine, Chinese Herbal Medicine, Acupuncture, Massage & Bone Setting, Qigong, and TCM diet were introduced in the behavioral part. In the third part, we aimed to collect personal, professional, and structural factors that may significantly influence TCM attitudes and behaviors. Physicians hold positive attitudes toward TCM in general, all the mean/highest possible subscales scores value of Holism (90.53%), Knowledge (63.77%), and Evidence (62.73%) domain were over 60%. On the other hand, physicians were more positive on self-use (49.40%) and recommendation (55.98%) of TCM than giving TCM prescriptions (36.60%) to patients. The attitudes and behaviors toward may not be consistent, which means physicians may not give prescriptions to patients even they have good attitudes to TCM. Education and self-use of TCM are important positive factors that influence the behaviors of physicians.
Bioinformatics analysis highlights CCNB1 as a potential prognostic biomarker and an anti-kidney renal papillary cell carcinoma drug target
Authors: Gong Xiaoming , Gong Yahong , Wu GuiFang , Ke Hengning
Published: April 2024

Kidney renal papillary cell carcinoma (KIRP) is a common urinary tumor that causes lymph node invasion. Once metastatic, the prognosis is poor and there is a lack of effective early diagnostic markers for this tumor. The expression of CCNB1 in KIRP tumor tissues was significantly higher than that in normal tissues in The Cancer Genome Atlas database with or without the genotype-tissue expression database, and a consistent result was obtained in 32 paired tissues. In addition, CCNB1 expression increased remarkably with the progression of the T and M stages. Moreover, using the online HPA database, we verified that the immunohistochemical scores of CCNB1 in KIRP were higher than those in the normal kidney tissues. The higher expression group of CCNB1 showed a worse prognosis in KIRP. Moreover, the receiver operating characteristic curve, univariate and multivariate analyses, and construction of the column diagram further illustrated that CCNB1 was an independent prognostic factor for KIRP. Meanwhile, CCNB1 could better predict the 1- and 3-year survival rates of KIRP. Six genes were significantly and positively co-expressed with CCNB1. We also found that the CCNB1 high-expression group was enriched in the ECM_RECEPTOR_INTERACTION and FOCAL_ADHESION pathways. Finally, drug sensitivity analysis combined with molecular docking identified 5 targeting drugs with the strongest binding activity to CCNB1. CCNB1 is a potential and reliable biomarker for KIRP diagnosis and can be used to predict the survival of patients with KIRP. The 5 selected drugs targeting CCNB1 may provide new hopes for patients with KIRP metastasis.

Published: April 2024

Multidrug-resistant tuberculosis (MDR-TB) has imposed a significant economic and health burden worldwide, notably in China. Using whole genome sequence, we sought to understand the mutation and transmission of MDR-TB in Shandong. A retrospective study of patients diagnosed with pulmonary tuberculosis in Shandong from 2009 to 2018 was conducted. To explore transmission patterns, we performed whole genome sequencing on MDR-TB isolates, identified genomic clusters, and assessed the drug resistance of TB isolates. Our study analyzed 167 isolates of MDR-TB, finding that 100 were clustered. The predominant lineage among MDR-TB isolates was lineage 2, specifically with a notable 88.6% belonging to lineage 2.2.1. Lineage 4 constituted a smaller proportion, accounting for 4.2% of the isolates. We discovered that Shandong has a significant clustering percentage for MDR-TB, with Jining having the highest percentage among all Shandong cities. The clustering percentages of MDR-TB, pre-extensively drug-resistant tuberculosis, and extensively drug-resistant tuberculosis were 59.9%, 66.0%, and 71.4%, respectively, and the clustering percentages increased with the expansion of the anti-TB spectrum. Isolates from genomic clusters 1 and 3 belonged to lineage 2.2.1 and showed signs of cross-regional transmission. The distribution of rrs A1401G and katG S315T mutations in lineage 2.2.1 and 2.2.2 strains differed significantly (P < .05). MDR-TB isolates with rpoB I480V, embA-12C > T, and rrs A1401G mutations showed a higher likelihood of clustering (P < .05). Our findings indicate a significant problem of local transmission of MDR-TB in Shandong, China. Beijing lineage isolates and some drug-resistant mutations account for the MDR-TB transmission in Shandong.

Published: April 2024

This study aimed to investigate the impact of the latest guidelines on the real-world clinical practice of initial lipid-lowering therapy, especially on the use of ezetimibe and proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in China. All adult patients diagnosed with acute myocardial infarction in our hospital between August 31, 2018, and August 31, 2020, were divided into the following 2 groups: those patients treated before the latest guideline release, and those patients treated after the release. A propensity score-matched method was used, and logistic regression was used to assess the association with intensive statin, ezetimibe and PCSK9 inhibitor usage together with treatment results between the 2 groups. A total of 325 patients were enrolled in this study, including 141 patients who were admitted before the release of the latest guideline and 184 patients who were admitted after the release. After a median follow-up time of 8.20 months, the mean low-density lipoprotein cholesterol was 1.87 ± 0.59 mmol/L (1.87 ± 0.55 in the before group vs 1.88 ± 0.62 in the after group, P = .829). After propensity score matching, the initial usage of intensive statin therapy was decreased after guideline release without statistical significance (17.00% vs 28.00%, P = .090), whereas the usage of ezetimibe and PCSK9 inhibitors was increased (19.00% vs 8.00%, P = .039; and 10.00% vs 3.00%, P = .085, respectively). In logistic regression models, the release of the guideline was associated with a statistically significantly increased use of ezetimibe (odds ratio [OR]: 1.91; 95% confidence interval [CI]: 1.21, 3.02; P = .005), a marginally decreased use of intensive statins (OR: 0.68; 95% CI: 0.45, 1.03; P = .069) and a marginally increased use of PCSK9 inhibitors (OR: 1.31; 95% CI: 0.98, 1.76; P = .068). In this single-center, real-world data analysis, after the release of the 2019 European Society of Cardiology/European Atherosclerosis Society guidelines, an increasing number of patients with a recent acute myocardial infarction were initially receiving ezetimibe and PCSK9 inhibitors.

Published: April 2024

Lateral wedge insole (LWI) wear is a well-known conservative treatment for patients with knee osteoarthritis and is expected to decrease knee joint loading. Although the effect of LWI length on knee adduction moment (KAM) has been investigated, the biomechanical mechanism has not been fully investigated. Twelve healthy young subjects walked in the laboratory with and without 2 different lengths of LWIs. Three-dimensional motion analysis was performed to calculate the first and second peaks and impulses of the KAM during the stance phase. In addition, the knee-ground reaction force lever arm (KLA) and center of pressure (COP), ankle eversion moment, and ankle eversion angle were calculated. The first peak of KAM was lower, COP was displaced outward, and KLA was shorter with both LWIs attached. On the other hand, the second peak of KAM was lower with longer LWIs, COP was displaced outward, and KLA was shorter. The KAM impulse was significantly smaller in the condition with longer LWI than in the other conditions with smaller ankle eversion motion; longer LWI induced COP to the lateral side through the stance phase and kept KLA short, thus reducing the KAM impulse.

Published: April 2024

A 35-year-old woman underwent 18F-FDG PET/CT 2 months after a radical hysterectomy for uterine cervical cancer. An apparent FDG uptake was observed in an oval-shaped mass with an attached surgical clip in the right paracolic gutter. A similar non–FDG-avid mass with a clip was observed in the left. In this case, ovarian transposition had also been performed with metallic clips placed on both sides of the paracolic gutters. The increased FDG uptake in the right paracolic gutter was interpreted as physiological uptake in the right transposed ovary, not metastasis. Recognizing the possibility of FDG uptake in transposed ovaries is important.

Introduction

Cutaneous squamous cell carcinoma (cSCC) is the second most common skin cancer in the White population. Unfortunately, the prognosis of advanced cSCC is poor, and management can be challenging. Until recently, the choice of systemic medications was limited, and those that were available had modest efficacy. Cemiplimab is an anti–programmed cell-death protein 1 inhibitor and the first immunotherapeutic agent approved for the treatment of metastatic or locally advanced cSCC. The purpose of this study was to evaluate the efficacy of cemiplimab when used as adjuvant or neoadjuvant therapy in patients treated at our institution.

Methods

A retrospective review of patients with locally advanced or metastatic cSCC who were treated with cemiplimab as adjuvant or neoadjuvant therapy at a single institution between February 2019 and November 2022 was performed. Response to treatment was objectively assessed based on Response Evaluation Criteria in Solid Tumors, version 1.1, criteria. The primary end point was objective response rate. Secondary endpoints included time to observed response, disease-control rate, progression-free survival, overall survival, and adverse effects of therapy.

Results

A total of 6 patients were identified with a median age of 79 years (range, 51–90 years). Four patients had locally advanced cSCC, and 2 had distant metastasis. Cemiplimab was used as adjuvant therapy in 3 patients and neoadjuvant therapy in 2 patients. There was 1 patient in which it was used for limb salvage, who would have otherwise required an amputation. Objective response rate, complete response, and partial response were 66% (4 of 6), 33% (2 of 6), and 33% (2 pf 6), respectively. Average time to observed response was 2.9 months. Disease-control rate was 83% (5 of 6), and average progression-free survival was 10 months. Toxicity was reported in 2 patients, both of which were grade 1 severity.

Conclusions

Cemiplimab has established its utility in the treatment of advanced cSCC, demonstrating clinical efficacy while generally having a tolerable adverse effect profile. Our preliminary results suggest that cemiplimab has potential as an adjuvant or neoadjuvant therapy in combination with surgery for treatment of cSCC.

Background

Tissue expansion has been widely used to reconstruct soft tissue defects following burn injuries in pediatric patients, allowing for satisfactory cosmetic and functional outcomes. Factors impacting the success of tissue expander (TE)-based reconstruction in these patients are poorly understood. Herein, we aim to determine the risk factors for postoperative complications following TE-based reconstruction in pediatric burn patients.

Methods

A retrospective review of pediatric patients who underwent TE placement for burn reconstruction from 2006 to 2019 was performed. Primary outcomes were major complications (TE explantation, extrusion, replacement, flap necrosis, unplanned reoperation, readmission) and wound complications (surgical site infection and wound dehiscence). Descriptive statistics were calculated. The association between primary outcomes, patient demographics, burn characteristics, and TE characteristics was assessed using the chi-squared, Fisher's exact, and Mann-Whitney U tests.

Results

Of 28 patients included in the study, the median [interquartile range (IQR)] age was 6.5 (3.3–11.8) years, with a follow-up of 12 (7–32) months. The majority were males [n = 20 (71%)], Black patients [n = 11 (39%)], and experienced burns due to flames [n = 78 (29%)]. Eleven (39%) patients experienced major complications, most commonly TE premature explantation [n = 6 (21%)]. Patients who experienced major complications, compared to those who did not, had a significantly greater median (IQR) % total body surface area (TBSA) [38 (27–52), 10 (5–19), P = 0.002] and number of TEs inserted [2 (2–3), 1 (1–2), P = 0.01]. Ten (36%) patients experienced wound complications, most commonly surgical site infection following TE placement [n = 6 (21%)]. Patients who experienced wound complications, compared to those who did not, had a significantly greater median (IQR) %TBSA [35 (18–45), 19 (13–24), P = 0.02].

Conclusion

Pediatric burn injuries involving greater than 30% TBSA and necessitating an increasing number of TEs were associated with worse postoperative complications following TE-based reconstruction.

Atypical meningiomas, classified as World Health Organization (WHO) grade-2 tumors, are characterized by varied and unpredictable clinical behavior. Here, we report the case of an 80-year-old woman with a large meningioma displaying communication both intracranially and extracranially. The histopathological diagnosis confirmed a WHO grade-2 atypical meningioma. After complete surgical resection, the patient experienced a significant improvement in symptoms, with no evidence of recurrence on follow-up imaging. This case highlights the significance of understanding giant intracranial and extracranial communication meningiomas, shedding light on the favorable prognosis associated with WHO grade-2 atypical meningiomas after complete surgical resection.

Objective:

To develop an artificial intelligence (AI) system for the early prediction of residual cancer burden (RCB) scores during neoadjuvant chemotherapy (NAC) in breast cancer.

Summary Background Data:

RCB III indicates drug resistance in breast cancer, and early detection methods are lacking.

Methods:

This study enrolled 1048 patients with breast cancer from four institutions, who were all receiving NAC. Magnetic resonance images were collected at the pre- and mid-NAC stages, and radiomics and deep learning features were extracted. A multitask AI system was developed to classify patients into three groups (RCB 0-I, II, and III ) in the primary cohort (PC, n=335). Feature selection was conducted using the Mann-Whitney U- test, Spearman analysis, least absolute shrinkage and selection operator regression, and the Boruta algorithm. Single-modality models were developed followed by model integration. The AI system was validated in three external validation cohorts. (EVCs, n=713).

Results:

Among the patients, 442 (42.18%) were RCB 0-I, 462 (44.08%) were RCB II and 144 (13.74%) were RCB III. Model-I achieved an area under the curve (AUC) of 0.975 in the PC and 0.923 in the EVCs for differentiating RCB III from RCB 0-II. Model-II distinguished RCB 0-I from RCB II-III, with an AUC of 0.976 in the PC and 0.910 in the EVCs. Subgroup analysis confirmed that the AI system was consistent across different clinical T stages and molecular subtypes.

Conclusions:

The multitask AI system offers a noninvasive tool for the early prediction of RCB scores in breast cancer, supporting clinical decision-making during NAC.

Objective:

This study aims to evaluate short- and long-term outcomes following pancreatectomy in patients with LAPC compared to (B)RPC patients.

Summary Background Data:

Selected patients diagnosed with locally advanced pancreatic cancer (LAPC) are increasingly undergoing resection following induction chemotherapy. To evaluate the benefit of this treatment approach, it is helpful to compare outcomes in resected patients with primary LAPC to outcomes in resected patients with primary (borderline) resectable pancreatic cancer ((B)RPC).

Methods:

Two prospectively maintained nationwide databases were used for this study. Patients with (B)RPC undergoing upfront tumor resection and patients with resected LAPC after induction therapy were included. Outcomes were postoperative pancreas-specific complications, 90-day mortality, pathological outcomes, disease-free interval (DFI), and overall survival (OS).

Results:

Overall, 879 patients were included; 103 with LAPC (12%) and 776 with (B)RPC (88%). LAPC patients had a lower WHO performance score and CACI. Postoperative pancreas-specific complications were comparable between groups, except delayed gastric emptying grade C, which occurred more often in LAPC patients (9% vs. 3%, P=0.03). Ninety-day mortality was comparable. About half of the patients in both groups (54% in LAPC vs. 48% in (B)RPC), P=0.21) had a radical resection (R0). DFI was 13 months in both groups (P=0.12) and OS from date of diagnosis was 24 months in LAPC patients and 19 months in (B)RPC patients (P=0.34).

Conclusions:

In our nationwide prospective databases, pancreas-specific complications, mortality and survival in patients with LAPC following pancreatectomy are comparable with those undergoing resection for (B)RPC. These outcomes suggest that postoperative morbidity and mortality after tumor resection in carefully selected patients with LAPC are acceptable.

With the growth of the older adult population, the number of older adults waitlisted for and undergoing kidney and liver transplantation has increased. Transplantation is an important and definitive treatment for this population. We present a contemporary review of the unique preoperative, intraoperative, and postoperative issues that patients older than 65 y face when they undergo kidney or liver transplantation. We focus on geriatric syndromes that are common in older patients listed for kidney or liver transplantation including frailty, sarcopenia, and cognitive dysfunction; discuss important considerations for older transplant recipients, which may impact preoperative risk stratification; and describe unique challenges in intraoperative and postoperative management for older patients. Intraoperative challenges in the older adult include using evidence-based best anesthetic practices, maintaining adequate perfusion pressure, and using minimally invasive surgical techniques. Postoperative concerns include controlling acute postoperative pain; preventing cardiovascular complications and delirium; optimizing immunosuppression; preventing perioperative kidney injury; and avoiding nephrotoxicity and rehabilitation. Future studies are needed throughout the perioperative period to identify interventions that will improve patients’ preoperative physiologic status, prevent postoperative medical complications, and improve medical and patient-centered outcomes in this vulnerable patient population.
