Objectives:

While COVID-19 continues to challenge the world, meteorological variables are thought to impact COVID-19 transmission. Previous studies showed evidence of negative associations between high temperature and absolute humidity on COVID-19 transmission. Our research aims to fill the knowledge gap on the modifying effect of vaccination rates and strains on the weather-COVID-19 association.

Methods:

Our study included COVID-19 data from 439 cities in 22 countries spanning 3 February 2020 – 31 August 2022 and meteorological variables (temperature, relative humidity, absolute humidity, solar radiation, and precipitation). We used a two-stage time-series design to assess the association between meteorological factors and COVID-19 incidence. For the exposure modeling, we used distributed lag nonlinear models with a lag of up to 14 days. Finally, we pooled the estimates using a random effect meta-analytic model and tested vaccination rates and dominant strains as possible effect modifiers.

Results:

Our results showed an association between temperature and absolute humidity on COVID-19 transmission. At 5 °C, the relative risk of COVID-19 incidence is 1.22-fold higher compared to a reference level at 17 °C. Correlated with temperature, we observed an inverse association for absolute humidity. We observed a tendency of increased risk on days without precipitation, but no association for relative humidity and solar radiation. No interaction between vaccination rates or strains on the weather-COVID-19 association was observed.

Conclusions:

This study strengthens previous evidence of a relationship of temperature and absolute humidity with COVID-19 incidence. Furthermore, no evidence was found that vaccinations and strains significantly modify the relationship between environmental factors and COVID-19 transmission.
The Hypocritical Oath? Unintended Consequences of Prenatal Substance Use Policies and Considerations for Health Care Providers
Authors: Philippopoulos Anastasia J. , Brown Zoe E. , Lewkowitz Adam K. , Howard Elisabeth D. , Micalizzi Lauren
Published: November 2024

Prenatal substance use (PSU) is a serious perinatal health issue in the United States with consequential health effects. To address this issue and protect children from the detrimental effects of substance exposure during pregnancy, the US government amended the Child Abuse Prevention and Treatment Act to provide funding to states with protocol to notify child protective services of PSU cases and develop treatment plans for affected families. Although well-intentioned, this statute resulted in diverse inter- and intrastate interpretations and implementation of PSU regulations nationwide, ultimately leading to mass confusion about who the policy applies to and when it should be applied. PSU policies are largely punitive in nature, which has led to null or adverse effects on perinatal outcomes. Treatment-prioritizing policies present hope for supporting birthing parents who use substances; however, their potential benefits are obstructed by fear and confusion instilled by coexisting punitive policies, stigma of disclosing substance use during pregnancy, variable or lack of screening methods, and insufficient knowledge about PSU health risks and counseling methods.

Precis: Punitive prenatal substance use policies may result in adverse perinatal outcomes. Treatment-oriented protocols and legislation should be prioritized.

Published: November 2024

Patients with both diabetes and coronavirus disease 2019 (COVID-19) are more likely to experience negative outcomes. This study aimed to identify the risk factors associated with these adverse outcomes that can assist clinicians in implementing suitable treatment strategies to minimize the occurrence of severe complications. A total of 92 patients with diabetes and COVID-19 in the Endocrine Department of Zhejiang Provincial Hospital of Chinese Medicine from December 2022 to February 2023 were enrolled and divided into the recovered group and the transfer to the intensive care unit (ICU) or death group. The clinical characteristics and infection indicators were compared between the 2 groups. Additionally, the patients were further divided into the normal group and the reduction group based on their glomerular filtration rate (GFR), and their clinical characteristics and infection indicators were also analyzed. Compared with the GFR normal group, the GFR reduction group exhibited worse outcomes, higher COVID-19 severity, a higher proportion of mechanical ventilation, and a longer hospital stay. However, there were no significant differences in leukocyte, lymphocyte, and neutrophil counts between these 2 groups. Compared with the recovered group, the transfer to ICU or death group demonstrated an increase in leukocytes and neutrophils, while lymphocytes decreased (P < .05). The C-reactive protein, procalcitonin, interleukin-6, and serum amyloid A levels in the transfer to ICU or death group were significantly higher than those in the Recovered group (P < .05). In addition, C-reactive protein, procalcitonin, and serum amyloid A levels in the GFR reduction group were significantly higher than those in the normal group (P < .05), while interleukin-6 levels were only slightly higher (P > .05). In clinical treatment, it is necessary to monitor infection indicators and GFR closely and intervene in time to reduce the occurrence of adverse events.

The 2019 coronavirus disease pandemic disrupts synchronized lifestyles and influences an individual’s health status. However, Taiwan has limited studies on the impact of the epidemic on the health and lifestyle of its citizens. This study aims to investigate the impact on lifestyle and health status during the first wave of 2019 coronavirus disease in Taiwan. The 2008 to 2021 Taiwan Biobank database was adopted in this study, covering 29,572 participants and was designed into 3 time periods, Episodes 1, 2, and 3. The definition of metabolic syndrome (MetS) is based on the strict ministry of health and welfare. Logistic regression model was used to explore related risk factors. Prevalence rates of MetS were 16.5%, 17.0%, and 18.7% during Episodes 1, 2, and 3, respectively. When compared to the pre-pandemic prevalence of MetS, the odds ratios increased by 1.19 [95% confidence intervals (CIs): 1.02–1.38] during the nationwide Level 3 epidemic alert, particularly, in male aged 45 to 64 years old and females aged under 45 years old by 1.56 (95% CI: 1.14–2.13) and 1.89 (95% CI: 1.22–2.92), respectively. During pandemic, sweeping influences on Taiwanese health status, especially in the labor force, may provide a lesson in health promotion policy at a specific age.

Published: November 2024

Deep vein thrombosis (DVT) is a serious condition characterized by blood clots in deep veins, posing a significant public health burden. Muscle strength has been implicated as a potential risk factor for DVT due to its influence on venous return. This study aims to investigate the causal association between muscle strength and DVT using a Mendelian randomization (MR) approach, leveraging genetic variants as instrumental variables (IVs). We conducted a 2-sample MR analysis using genome-wide association study (GWAS) data for hand-grip strength and DVT. IVs were selected based on their significant associations with muscle strength and DVT, as well as their linkage disequilibrium patterns. We employed statistical methods including inverse-variance weighting (IVW), MR-Egger, and weighted median to address pleiotropy bias. Sensitivity analyses were conducted to evaluate the robustness of the results. A total of 21 and 14 independent IVs were identified for hand grip strength (EWGSOP) and hand grip strength (FNIH), respectively. IVW analysis revealed a consistent causal and negative association between both definitions of hand grip strength and DVT (EWGSOP: OR = 0.702, 95% CI: 0.511–0.964, P = .029; FNIH: OR = 0.715, 95% CI: 0.570–0.898, P = .004). No directional pleiotropy was detected in MR-Egger and MR-PRESSO analyses for either definition (EWGSOP: MR-Egger Intercept P = .516; MR-PRESSO global test P = .162; FNIH: MR-Egger Intercept P = .569; MR-PRESSO global test P = .371).Sensitivity analyses demonstrated the stability of the causal effect estimates, with little influence from individual IVs. The MR analysis provided evidence of a causal association between muscle strength and DVT risk, suggesting that increasing muscle strength may have a protective effect. These findings have implications for preventive strategies and the promotion of resistance exercises and muscle-strengthening activities. Further research and validation of these results could inform clinical guidelines and interventions for DVT prevention.

Published: November 2024

Oral squamous cell carcinoma (OSCC) is a tumor type with a high mortality rate. Chlorogenic acid, abundant in resources and widely utilized in cancer treatments, has seen limited studies regarding its efficacy against OSCC. This paper investigates chlorogenic acid’s mechanism in treating OSCC, aiming to guide the development of novel drugs. The study employed network pharmacology, molecular docking, and survival analysis methods. Network pharmacological analysis revealed chlorogenic acid targets 23 OSCC-related proteins, including ESR1, MMP2, MMP9, SRC, MAPK8, MAPK1, CDC42, ERBB2, ATM, and BRAF. Molecular docking simulations indicated that the primary target exhibits significant binding capacity with chlorogenic acid, with MMP9 associated with tumor migration and angiogenesis standing out. Survival analysis demonstrated that the downregulation of most primary targets correlates with improved survival rates in OSCC patients. Enrichment analysis of therapeutic targets highlighted the pivotal role of MAPK-ERK and MAPK-JNK signaling pathways in chlorogenic acid’s efficacy against OSCC. This paper predicts chlorogenic acid’s potential targets and proposes its molecular mechanism in treating OSCC, offering a theoretical foundation for its application in OSCC treatment. We used traditional Chinese medicine, a disease pharmacology-related information base, and an analysis platform to predict targets. The Cytoscape 3.9.1 and STING databases were used to address common targets for drugs and diseases, establish networks of protein interaction relationships, and screen core targets. Meastro11.5 was used for molecular docking simulation. R4.2.2 was used for survival analysis and joint target enrichment analysis. Network pharmacological analysis identified chlorogenic acid acting on 23 OSCC targets. Molecular docking simulations revealed a strong binding affinity of chlorogenic acid compounds with these targets, particularly MMP9, essential for tumor migration and angiogenesis. Survival analysis indicated that the downregulation of most core targets was correlated with improved OSCC patient survival. Enrichment analysis of therapeutic targets highlighted the critical roles of the MAPK-ERK and MAPK-JNK signaling pathways in the effectiveness of chlorogenic acid against OSCC. This study predicted the potential targets of chlorogenic acid in OSCC treatment and hypothesized its molecular mechanism, offering a theoretical foundation for its use in OSCC therapy.

Published: November 2024

To investigate the effect of extracorporeal shock wave on the treatment of talus bone marrow edema by regulating subchondral bone homeostasis through tumor necrosis factor-α (TNF-α)/hypoxia-inducible factor-1α (HIF-1α)/vascular endothelial growth factor (VEGF) signaling pathway. A total of 81 patients with talus bone marrow edema admitted to our hospital from May 2019 to May 2021 were studied and divided into control group (n = 40) and extracorporeal shock group (n = 41) according to random number table method. The control group was given conventional treatment, and the extracorporeal shock group was combined with extracorporeal shock wave therapy on the basis of the control group. The expression of TNF-α, HIF-1α, and VEGF in the 2 groups were compared, pain degree, and the area of talus bone marrow edema was evaluated by magnetic resonance imaging. The visual analogue scale scores of 1 month, 2 months and 5 months after treatment were decreased in both groups, and the extracorporeal shock group was lower than the control group (P < .05). After 5 months of treatment, the expressions of TNF-α and HIF-1α were decreased in both groups, and the extracorporeal shock group was lower than the control group, VEGF was increased, and the extracorporeal shock group was higher than the control group (P < .05), and the western blot expression levels of TNF-α, HIF-1α and VEGF in the extracorporeal shock group were higher than the control group (P < .05). The dorsiflexion motion and plantar flexion motion of both groups were increased, and the extracorporeal shock group was higher than the control group (P < .05). Extracorporeal shock wave therapy can regulate subchondral bone homeostasis through TNF-α/HIF-1α/VEGF signaling pathway to treat talus bone marrow edema, reduce the pain degree of talus bone marrow edema, and improve ankle joint function.

Authors: Han Xiaona , Zhang Xiaotao , Lin Yaru , Li Jinying , Yu Lan , Liu Li , Tong Wenzhi , Cheng Xi , Li Xiao , Liu Yanhao
Published: November 2024

Background:

Stereotactic body radiotherapy (SBRT) and immune checkpoint inhibitors (ICIs) could obtain a certain synergistic effect on bone and soft tissue sarcoma (BSTS). Given its low radiosensitivity, BSTS usually require an irradiation dose >65 Gy to achieve local control. Herein, we developed a non-classical SBRT technique called “onion-shaped simultaneous boost (OSB),” and reported a patient with prostatic leiomyosarcoma which received non-classical SBRT and other systemic treatments.

Methods:

In the case, a 49-year-old male patient was diagnosed with prostatic leiomyosarcoma in November 2018. In the radiotherapy plans, the maximum doses of the targets were more than 65 Gy, while the doses of the organs at risk (OARs) were strictly limited.

Results:

After receiving radiotherapy, ICI, and other multidisciplinary modalities, the patient achieved partial response (PR).

Conclusion:

In this clinical case, we have observed that the OSB technique, which employs an increased per-fraction radiotherapy dose without the need to match the single-fraction doses typical of conventional SBRT, effectively enhances the therapeutic impact on leiomyosarcoma without an increase in radiotherapy-related side effects. By integrating the OSB technique with a multidisciplinary array of antineoplastic strategies, we can more effectively manage sarcomas in clinical practice.

Authors: Xie Min , Chen Sisi , He Qiqiang
Published: November 2024

This study aims to investigate the fear and compliance of Insulin Degludec and Insulin Aspart (IDegAsp) injection in type 2 diabetes mellitus (T2DM) patients and study the factors influencing patient compliance. A total of 120 patients with T2DM treated from February 2019 to March 2022 were investigated and analyzed for fear and compliance on the Diabetes Fear of Injecting and Self-testing Questionnaire of diabetic patients and were divided into compliance and noncompliance groups according to the results to analyze the factors affecting patient compliance. The study found a high level of fear of IDegAsp injection among the 120 T2DM patients, with an average Diabetes Fear of Injecting and Self-testing Questionnaire score of (39.19 ± 4.59) points. Scores for medication compliance, dietary compliance, blood sugar monitoring, and lifestyle changes were (10.48 ± 1.52) points, (12.18 ± 2.27) points, (0.84 ± 0.12) points, and (9.13 ± 2.21) points, respectively. There was no significant difference between the compliance and noncompliance groups in terms of gender, age, lifestyle, educational level, occupation, current treatment method, family monthly income per capita, and medical payment method (P > .05). However, there were significant differences influenced by disease duration, complications, cognitive level, self-efficacy level, comorbidity count, and living status (P < .05). Multifactorial analysis showed that educational level, disease duration, complications, cognitive level, self-efficacy level, comorbidity count, and living status all affected patient compliance (P < .05). Educational level, disease duration, complications, cognitive level, self-efficacy level, comorbidity count, and living status are important factors affecting the fear and treatment compliance of IDegAsp injection in T2DM patients. These findings have implications for improving patient compliance and alleviating treatment fear.

To investigate the clinical characteristics, treatment methods, and factors influencing the prognosis of patients with severe pneumonia complicated by Acute Respiratory Distress Syndrome (ARDS), aiming to provide references for clinical decision-making and improve patient outcomes. A retrospective analysis was conducted on 118 patients with severe pneumonia complicated by ARDS treated at our hospital from June 2018 to December 2022. Based on treatment outcomes, patients were divided into a death group (n = 75) and a survival group (n = 43). General data and clinical laboratory indicators, including blood urea nitrogen, serum creatinine, C-reactive protein, procalcitonin, arterial partial pressure of oxygen, and arterial partial pressure of carbon dioxide, were collected and compared between the 2 groups to identify independent factors affecting prognosis. Among the 118 patients, the mortality rate was 63.56%. Patients in the death group had a significantly higher average age (57.15 ± 13.38 years) and a higher proportion of severe ARDS (66.67%) compared to the survival group (40.02 ± 11.41 years, 30.23%, P < .001). The death group had significantly lower white blood cell counts (8.10 ± 1.64 × 109/L), oxygenation index (19.82 ± 2.29), and duration of mechanical ventilation (7.79 ± 2.11 days) compared to the Survival group (8.92 ± 1.22 × 109/L, 13.42 ± 1.82, 12.23 ± 3.05 days, P < .05). Conversely, the death group had significantly higher levels of blood urea nitrogen (6.87 ± 1.80 mmol/L), C-reactive protein (130.55 ± 50.28 mg/L), procalcitonin (5.50 ± 2.11 ng/mL), arterial partial pressure of carbon dioxide (41.12 ± 5.56 mm Hg), and a higher proportion of viral infections (48.00%) compared to the survival group (5.90 ± 1.72 mmol/L, 101.77 ± 55.56 mg/L, 3.98 ± 1.15 ng/mL, 35.59 ± 6.22 mm Hg, 27.91%, P < .05). Logistic regression analysis revealed that age (odds ratios [OR] = 1.990, 95% confidence interval [CI]: 1.306–3.033, P < .001), oxygenation index (OR = 1.426, 95% CI: 1.123–1.649, P < .001), and duration of mechanical ventilation (OR = 0.694, 95% CI: 0.557–0.864, P < .001) were independent factors influencing patient prognosis. This indicates that an increase in age and a decrease in oxygenation index are associated with a significantly higher risk of mortality, while shorter mechanical ventilation duration is related to poorer prognosis. Advanced age, lower oxygenation index, and shorter duration of mechanical ventilation are unfavorable prognostic factors in patients with severe pneumonia complicated by ARDS. These findings aid clinicians in identifying high-risk patients, optimizing treatment plans, and improving patient prognosis.
Low-dose apatinib in combination with chemotherapy for hormone receptor-positive, HER2-negative breast cancer with pulmonary lymphangitic carcinomatosis: A case report
Authors: Chen Liping , Feng Sha , Chen Xuelian , Du Caiwen
Published: November 2024

Rationale:

Hormone receptor-positive, HER2-negative advanced breast cancer complicated by pulmonary lymphangitic carcinomatosis (PLC) poses significant therapeutic challenges due to the lack of standardized treatment protocols. Despite various therapeutic interventions and supportive care, prognosis remains dismal.

Patient concerns:

Herein, a 48-year-old Chinese woman presented with a persistent cough, unresponsive to anti-infective treatment for 1 month. A computed tomography (CT) scan revealed lymphatic vessel infiltration and a diffuse nodular pattern, suggestive of PLC.

Diagnoses:

Hormone receptor-positive, HER2-negative advanced breast cancer complicated by PLC.

Interventions:

The patient was treated with a regimen comprising low-dose apatinib, capecitabine, and albumin-bound paclitaxel.

Outcomes:

The patient achieved a partial response, with a progression-free survival exceeding beyond ten months. Symptoms of dyspnea and dry cough significantly improved, alongside a notable reduction in lymphangitic carcinomatosis.

Lessons:

This case highlights the potential antitumor activity of apatinib in breast cancer patients with presenting with PLC. While further studies are necessary, this therapeutic approach could represent a viable option for managing breast cancer in the context of a visceral crisis. The case also emphasizes the importance of individualized treatment strategies and further research to substantiate these promising findings.

Published: November 2024

Drug-induced liver injury (DILI) is a major concern in tuberculosis (TB) treatment. For early detection of DILI, immune-inflammatory biomarkers are needed for better management. To explore the predictive effect of systemic immune-inflammation index (SII) combined with neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), eosinophil (EOS%), and CD4/CD8 on DILI occurrence in TB patients with HBsAg positive. This is a retrospective study enrolling patients who were treated with anti-tuberculosis drugs and infected with hepatitis B virus (HBV) in the Guangzhou Chest Hospital from 2018 to 2023. Population demographics and clinical data of 2643 patients were collected by reviewing electronic medical records. Using a propensity score matching model, the study ultimately included 516 patients (258 patients with DILI and 258 patients without DILI). Logistic regression analysis was conducted to investigate the predictive role of systemic immune-inflammatory biomarkers (SII, NLR, MLR, EOS%, and CD4/CD8) in DILI in hepatitis B virus surface antigen-positive TB patients (HBV-TB-DILI). As compared to patients without DILI, patients with DILI have elevated levels of systemic immune-inflammatory biomarkers (SII, NLR, MLR, EOS%, and CD4/CD8), (all P < .05). The SII, NLR, MLR, PLR, EOS%, and CD4/CD8 are risk factors of HBV-TB-DILI. The NLR, MLR, SII, and EOS% were positively correlated with liver function (P < .001). The combination of SII, NLR, MLR, EOS%, and CD4/CD8 demonstrated good predictive performance for DILI occurrence in HBV-TB patients. The combination of SII, NLR, MLR, EOS%, and CD4/CD8 demonstrated good predictive performance for DILI occurrence in HBV-TB patients.

Authors: Yang Tao , Huang Chunyan , Chen Yulin , Lei Xuemin
Published: November 2024

To explore the value of ultrasound in volume assessment during the perioperative period of single-shot spinal anesthesia for total hip arthroplasty. A total of 100 patients undergoing elective surgery under spinal anesthesia at our hospital from January 2022 to January 2024 were selected. Transthoracic echocardiography was used to measure the diameter of the abdominal aorta (Ao) before anesthesia (T1), 10 minutes after anesthesia (T2), and 30 minutes after anesthesia (T3). The inferior vena cava collapsibility index (IVC-CI) and the ratio of IVCe to Ao (IVCe/Ao) were calculated. A volume load test was performed 10 minutes after anesthesia. Based on the increase in stroke volume (ΔSV) after the volume load test, patients were divided into a volume-responsive group (ΔSV ≥ 15%) and a volume-nonresponsive group (ΔSV < 15%). The reliability of inferior vena cava parameters in predicting hypotension after spinal anesthesia and the value in predicting volume responsiveness postanesthesia were evaluated using ROC curves. A total of 100 patients were enrolled, 18 were withdrawn, and a total of 82 patients were included. After the volume load test, the parameters of the volume response group and the volume nonresponse group were basically consistent, and the difference was not statistically significant (P > .05). The SV of volume reaction group was significantly higher than that of volume no reaction group (P < .05). The incidence of hypotension in the volume response group was higher than that in the non-volume response group (51.28% vs 11.63%, χ
2 = 15.174, P < .01). The AUC for volume reactivity prediction using IVCe, IVCi, IVC-CI, and IVCe/Ao were 0.62, 0.71, 0.70, and 0.72, respectively. IVCi, IVC-CI, and IVCe/Ao were significant predictors of volume reactivity (P < .05). The AUC predicting persistent hypotension after spinal anesthesia using IVCe, IVCi, IVC-CI, and IVCe/Ao were 0.78, 0.79, 0.70, and 0.84, respectively. IVCe, IVCi, IVC-CI, and IVCe/Ao can predict volume reactivity before anesthesia. IVCi, IVC-CI, and IVCe/Ao predicted persistent hypotension in patients with spinal anesthesia after anesthesia, and IVCe/Ao showed the best predictive effect. Thus, IVCe/Ao is a reliable parameter for predicting persistent hypotension and assessing volumetric reactivity.

Authors: Hu Jing , Fu Shouzhi
Published: November 2024

This study aims to explore the perioperative nursing effect of vacuum sealing drainage closed negative pressure drainage in the treatment of emergency traumatic wound infection. A total of 116 patients with trauma-related wound infection were admitted to the Department of orthopedics and skin wound at our hospital from April 2021 to October 2022 were selected as the study subjects. They were divided into an observation group and a control group, with 58 patients in each group. Patients in the control group received traditional wound debridement, while patients in the observation group underwent debridement with the addition of vacuum-sealed drainage closed negative pressure. The treatment outcomes, pain levels, various treatment indicators, and wound healing conditions of the 2 groups were compared. The overall effective rate of treatment in the observation group was 93.10%, which was significantly higher than the control group’s rate of 75.86% (P < .05). The Visual Analog Scale scores of patients in both groups were compared at 1 hour after treatment and 6 hours after treatment (P > .05). However, at 12 hours and 24 hours after treatment, the Visual Analog Scale scores of patients in the observation group were significantly lower than those in the control group (P < .05). The observation group of patients had fewer changes of dressings after treatment compared to the control group (P < .05). The wound healing time, antibiotic usage duration, and hospitalization time were all shorter in the observation group than in the control group (P < .05). The Bates–Jensen scores of both groups of patients before treatment were compared (P > .05). After treatment, the Bates–Jensen scores in both groups decreased, and the observation group had lower scores than the control group (P < .05). The use of vacuum sealing drainage closure therapy in patients with emergency trauma-related wound infections can alleviate pain, reduce the frequency of dressing changes, accelerate wound healing, and improve wound healing outcomes. It is worthy of clinical promotion.

To explore the factors influencing the clinical pregnancy rate in the Reproductive Center of the Affiliated Hospital of North Sichuan Medical College in the second cycle, a retrospective analysis of the clinical data of 175 patients who underwent the second cycle of intrauterine insemination (175 cycles) from July 2019 to July 2022 was performed. According to whether the patients reached clinical pregnancy, they were divided into the pregnant group (32 cycles) and non-pregnant group (143 cycles). The age, infertility years, infertility factors, infertility type, number of sinus follicles, intimal thickness, intimal type, basal follicle-stimulating hormone, basal luteinizing hormone, basal estradiol, stimulation regimen, season, body mass index, and male semen quality were statistically analyzed between the 2 groups. The number of intrauterine insemination (IUI) in the second cycle was 175, and the clinical pregnancy rate was 18.3% (32/175). The age of the pregnant group was lower than that of the non-pregnant group [(26.7 ± 1.07) vs (30.56 ± 0.51), P = .05]. The clinical pregnancy rate in patients aged ≤30 years was significantly higher than that in patients aged > 30 years [28.6% vs 7.1%, P < .05]. Among infertility factors, the pregnancy rate of patients who underwent IUI due to female factors was significantly higher than that of male factors, combined factors (both male and female), and unexplained infertility, and the differences were statistically significant [37.1% vs 22.4%, 18.2%, 3.2%, P < .05]. In multivariate logistic regression analysis, age and infertility factors were independent influencing factors of clinical pregnancy rate in the second cycle of IUI. In, while in artificial insemination, female age and infertility factors were important factors affecting the clinical pregnancy rate of the second cycle of IUI. If the outcome of the first cycle is not pregnant, the female age is <30 years, infertility is the female factor, and the second cycle of IUI can be considered.

The aim was to study the validity of free-standing position using modifiers for assessing cervical spine alignment. A total of 26 asymptomatic subjects (45 ± 11years) and 13 with spinal deformities (30 ± 21years) underwent lateral radiographs using EOS®, while adopting 3 different positions, in 2 sequences, without mirror and then with mirror (m) placed in front of them: first, the neutral standing position (upper extremities positioned on the sides of the body, P1 and P1m), then free-standing (P2 and P2m) and modified free-standing (P3 and P3m) positions (shoulders flexed at 90° and fingers placed on clavicles then cheeks, respectively). Participants were asked not to move their trunk and shoulders when moving from P1 to P2 and then P3. Eighteen cervical radiographic parameters were calculated from the 6 radiographs. The effects of shoulder flexion, mirror placement, and finger positioning on cervical alignment were studied using a repeated-measures ANCOVA. Mirror placement had no effect on cervical alignment. Concerning the effect of shoulder flexion, C2–C7 and T1 slopes were significantly decreased in P2 and P2m (C2–C7 = 10° and 8°; T1 slope = 26° and 24°, respectively) and P3 and P3m (C2–C7 = 9° and 9°; T1 slope = 25° and 26°, respectively) compared to P1 and P1m (C2–C7 = 14°and 14°; T1 slope = 29°and 30°, respectively), without exceeding the uncertainty level. Assessment of cervical alignment is valid on whole-spine radiographs when the shoulders are flexed (free-standing position). Clear instructions regarding the shoulder position at 90°, without moving the trunk, neck, and head before placing the fingers on the clavicles or cheeks, can ensure a cervical alignment comparable to that obtained with the neutral position, which is considered the most physiological one.

This study aims to rigorously explore the potential causal relationships among gut microbiota (GM), immune cells, and melanoma skin cancer among participants from Europe, where this disease exhibits significant prevalence and profound societal impact. Using the genome-wide association analysis database, a double-sample Mendelian randomization (MR) analysis was drawn upon to investigate GM, immune cells, and melanoma skin cancer. The inverse variance weighted approach was applied to estimate the causal connections among these variables. A two-step MR analysis was employed to quantitatively gauge the impact of immune cells mediated GM on melanoma skin cancer. To address potential sources of bias, such as pleiotropy and heterogeneity, multiple analytical techniques were integrated. The MR analysis pinpointed 6 GM taxa related to either an augmented or declined risk of late-stage melanoma skin cancer. In the same vein, 32 immune cell phenotypes were noticed as correlates with modified risk of melanoma skin cancer. Our study also implies that the probable association between GM and melanoma could be facilitated by 5 immune cell phenotypes. The findings of our study underline certain GM taxa and immune cells as potential influencers on the onset and development of melanoma skin cancer. Importantly, our results spotlight 5 immune cell phenotypes as potential agents mediating this association.
Mesocolic schwannoma mimicking gastrointestinal stromal tumor: A case report and review of literature
Authors: Sun Qihang , Zhu Qingshun , Lu Xuren , Zhu Guangxu , Lang Wei , Zhang Jie , Qu Jianjun
Published: November 2024

Rationale:

Schwannomas are common peripheral nerve tumors originating from Schwann cells, primarily occurring in the head and neck, limbs, and trunk. Schwannomas occurring in the mesocolon are rare and often have no specific manifestations. Abdominal schwannomas need to be differentiated from common abdominal tumors such as gastrointestinal stromal tumors.

Patient concerns:

We report a case of a mesocolic schwannoma in a 59-year-old female presenting with gastrointestinal symptoms of acid reflux. At an outside hospital, gastroscopy, colonoscopy, and abdominal computed tomography scans revealed a soft tissue mass adjacent to the greater curvature of the stomach, leading to a suspicion of a gastric mesenchymal tumor.

Diagnoses:

Mesocolic schwannoma.

Interventions:

Laparoscopy was performed at our hospital. Intraoperatively, the tumor was found to be closely related to the transverse colon and was initially diagnosed as a mass originating from the transverse colon. Consequently, a resection of the mass along with the adherent portion of the transverse colon was performed. Postoperative pathology and immunohistochemistry confirmed that the tumor was a schwannoma of the mesentery and did not originate from the transverse colon.

Outcomes and lessons:

Schwannomas can be distinguished from gastrointestinal stromal tumors by immunohistochemical staining, and surgical treatment is effective for benign schwannomas.
Prepatellar bursa mucosa: An unreported postoperative complication of patellar fracture
Authors: Lin Fukun , Yao Jihang , Liu Yiming , Qi Baochang
Published: November 2024

Background:

Patellar fracture is a common injury caused by overstrain of the extensor mechanism or a direct trauma to the knee. The most common complications after patellar fracture are nonunion, infection, post-traumatic arthritis, joint fibrosis, symptomatic hardware, and extensor mechanism failure. These are attributed to the post-fracture flexion and extension movements, the primary damage to the articular cartilage, and the thin soft tissue coverage over the knee. To our knowledge, prepatellar bursa mucosa is an unreported postoperative complication of patellar fracture.

Methods:

We describe a case of a 58-year-old woman with a left patellar fracture from a fall. Complete healing was achieved after in 2 months postoperatively using the improved Kirschner wire tension band and a cable grip system; however, at 7 months postoperatively, a prepatellar skin mass appeared. The patient reported prepatellar discomfort with no pain and influence of movement of the knee and daily life. One year postoperatively, we surgically removed the implants and mass. The pathological result showed bursa mucosa.

Results:

The literature review shows that pain, secondary knee dysfunction, fracture nonunion, and malunion are postoperative complications of patellar fractures. However, prepatellar bursa mucosa have not been previously reported as a postoperative complication.

Conclusion:

This case highlights the need for appropriate placement of the intraoperative implant in adults with patellar fractures.
Role of SIRPG gene in type 1 diabetes and lichen planus
Authors: Wu Ji , Zhao Honglei
Published: November 2024

Type 1 diabetes (T1D) is a form of diabetes caused by pancreatic β-cell destruction and absolute insulin deficiency. Lichen planus (LP) is an idiopathic inflammatory skin disease of unclear etiology. The role of SIRPG gene dysregulation in T1D and LP remains unclear. Mendelian randomization (MR) using matched samples was employed to study causal relationship between T1D and increased risk of LP. T1D-related single nucleotide polymorphism identification was conducted. Datasets GSE156035 for T1D and GSE52130 for LP were obtained from gene expression omnibus. Differentially expressed genes were identified, analyses included weighted gene co-expression network analysis, functional enrichment, gene set enrichment analysis, and protein–protein interaction network construction and analysis. Heatmaps of gene expression levels were generated. Comparative toxicogenomics database was used to identify diseases most relevant to core genes. Inverse variance weighted, MR-Egger, weighted median methods estimated genetic predisposition between T1D and LP, showing consistent positive correlations using both weighted median and inverse variance weighted methods. Horizontal pleiotropy analysis with MR-Egger intercept indicated no evidence of significant directional pleiotropy (P = .70645) for LP. There was no evidence of directional pleiotropy effects between T1D and LP. One hundred eighteen differentially expressed genes were identified. In biological processes, they were mainly enriched in apoptosis, inflammatory response, insulin receptor signaling pathway, glucose metabolism. In cellular components, enrichment was observed in mediator complex and replication fork. In molecular function, they were concentrated in leukotriene receptor activity and helicase activity. Kyoto Encyclopedia of Genes and Genomes analysis revealed enrichment in metabolic pathways, PI3K-Akt signaling pathway, cell cycle, p53 signaling pathway, AGE-RAGE signaling pathway in diabetic complications. Weighted gene co-expression network analysis with a soft threshold power of 4. SIRPG showing high expression in both T1D and LP samples. There is a positive causal relationship between T1D and LP. Comparative toxicogenomics database analysis revealed associations of core genes with metabolic syndrome, lipid metabolism disorders, cardiovascular diseases, immune system diseases, peripheral neuropathic pain, and inflammation. SIRPG is highly expressed in both T1D and LP, providing a new insight into the pathogenesis of T1D and LP.

Published: November 2024

Migraine and severe headaches are common neurological disorders with significant societal impact. Previous research indicates a potential link between serum folate levels and migraine occurrence, yet there is a lack of sufficient relevant studies and more are required. This study aimed to determine the association between a severe headache or migraine and serum folate levels in large populations. Using data from the National Health and Nutrition Examination Survey, we conducted a cross-sectional study. Using multivariable logistic regression models, we investigated the association between serum folate and severe headache or migraine. In a subsequent subgroup analysis, several confounding factors were also explored to investigate the association between migraine and serum folate. A total of 13,351 individuals participated in the study, with 2742 reporting severe headache or migraine in the previous 3 months. Serum folate was negatively associated with severe headache or migraine (odds ratio [OR] = 0.5, 95% confidence interval [CI] = 0.28–0.89, P = .018). The stratified analysis revealed this association persisted among female (OR = 0.38, 95% CI = 0.18–0.82, P < .001), individuals aged 20 to 50 years (OR = 0.53, 95% CI = 0.28–0.99, P < .001), and non-Hispanic White participants (OR = 0.38, 95% CI = 0.17–0.87, P < .001). We found that greater levels of serum folate were significantly related to a decreased likelihood of migraine onset, especially among women, young and middle-aged populations, and non-Hispanic White participants. Further research is required to validate and expand upon our results.

Authors: Zhang Li , Wu Jingjin
Published: November 2024

This study presents an in-depth exploration of various adjustment methods for intraoperative catheter malposition by guidewires in the implantation of totally implantable venous access ports (TIVAP). It not only aims to summarize these methods but also endeavors to identify the most advantageous approach. The patient list was searched using the hospital information system from January 1, 2022, to October 31, 2023. All patients who had undergone chest port placement using the axillary vein (AxV) or subclavian vein (SCV) approach were reviewed, and further imaging was performed to confirm the guidewire applied to adjust the guidewire or catheter from the internal jugular vein into the superior vena cava (SVC) under fluoroscopy. Demographic data, diagnoses, technical outcomes, and perioperative complications were collected. About 32 patients with an average age of 62.8 years were included in the study. The operation time was 29.3 ± 13.3 minutes and SVC selecting time was 16.9 ± 11.5 seconds. The dose of X-ray exposure was only 7.2 ± 9.0 μGym2. Adjustments combined the guidewire with the puncture needle had the shortest SVC selection time and operation time with a minimal radiation dose. intraoperative catheter malposition can be timely and effectively adjusted using guidewires under fluoroscopy during any process of TIVAP implantation. Timely adjustment using a guidewire after inserting into the puncture needle is an optimal choice for a smooth and successful operation.
