[PMID: 39695958 DOI: 10.1186/s12245-024-00774-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2024] [Accepted: 11/27/2024] [Indexed: 12/20/2024] Open
Abstract
Thromboembolic disorders, including deep vein thrombosis (DVT) and pulmonary embolism (PE), are major global health concerns, causing significant morbidity and mortality. Early diagnosis is crucial for effective treatment and improved patient outcomes. Recent research has identified Apelin-13, a bioactive peptide in the apelin family, as a promising diagnostic biomarker for Thromboembolic disorders. Apelin-13 supports vascular health by regulating protease balance through plasminogen activator inhibitors and modulating endothelial cell function. Additionally, it plays a vital role in coagulation, with elevated levels associated with an increased risk of clot formation, suggesting its utility in predicting thrombosis risk, particularly in preoperative evaluations. Findings indicate that the Apelin-13 pathway shows significant promise as a biomarker for Thromboembolic disorders, underscoring its potential therapeutic applications and the need for further investigation. This review synthesizes current literature on thromboembolic disorders and associated laboratory biomarkers, with a particular focus on Apelin-13. It examines Apelin-13's role in disease mechanisms, its physiological functions, and its potential as a diagnostic biomarker in thromboembolic conditions.

Investigation of the prevalence of latent tuberculosis in cancer patients compared to non-cancer patients: a case-control study. Oncol Rev 2024; 18:1445678. [PMID: 39697587 PMCID: PMC11652964 DOI: 10.3389/or.2024.1445678] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2024] [Accepted: 11/22/2024] [Indexed: 12/20/2024] Open
Abstract
Background Latent tuberculosis (TB) can reactivate in immunocompromised individuals, such as cancer patients undergoing chemotherapy, leading to severe complications. Understanding the prevalence of latent TB in this high-risk group is crucial, especially in regions with moderate to high TB burdens. Aim This study aims to determine the prevalence of latent tuberculosis in cancer patients before chemotherapy and immunotherapy to guide preventive interventions and reduce the risk of TB reactivation. Methods This case-control study was conducted at Sina Hospital in Tehran, Iran, from 2012 to 2022. A total of 392, including 107 newly diagnosed cancer (case) and 285 non-cancer (control) patients, were enrolled in this study. All patients had received the Bacillus Calmette-Guérin (BCG) vaccine at the age of one. They underwent a thorough clinical examination and were screened using the tuberculin skin test (TST) to detect latent TB. Any active TB cases were identified through acid-fast smear tests. The data collected from the study participants was then analyzed. Results The results showed no significant difference in the size of TST between cancer and non-cancer patients (cases: median = 2 mm, IQR: 1-12; controls: median = 2 mm, IQR: 1-5; p = 0.09). The prevalence of latent TB was 27.1% in cancer patients and 20.7% in non-cancer patients, with no significant association identified between latent TB and malignancies (P-value = 0.176). Over a median follow-up of 4 years, mortality was significantly higher in cancer patients compared to controls (42.1% vs 1.8%; P< 0.001, OR = 40.64). Additionally, deceased patients exhibited a greater prevalence of latent TB (44% vs 19.3% in survivors; P< 0.001, OR = 3.28), and increased size of TST was associated with higher mortality risk among cancer patients. Conclusion In conclusion, this study emphasizes the need for vigilant latent TB screening in cancer patients, given the association between larger TST sizes and increased mortality risk. While no direct link between cancer type and latent TB was found, proactive TB management remains crucial, particularly for those undergoing immunosuppressive therapy.

Effects of L-carnitine supplementation on lipid profile in adult patients under hemodialysis: a systematic review and meta-analysis of RCTs. Front Med (Lausanne) 2024; 11:1454921. [PMID: 39687901 PMCID: PMC11646722 DOI: 10.3389/fmed.2024.1454921] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2024] [Accepted: 11/20/2024] [Indexed: 12/18/2024] Open
Abstract
Background Chronic kidney disease (CKD) affects 10% of the global population and leads to end-stage renal disease (ESRD). Hemodialysis is a common treatment for ESRD, but patients often have low carnitine levels, leading to dyslipidemia, a risk factor for cardiovascular disease and the leading cause of mortality. This study aimed to assess the effects of L-carnitine on lipid profiles in adult hemodialysis patients. Methods A comprehensive search was conducted across the online databases from inception to June 2024 to identify randomized clinical trials (RCTs) evaluating the effects of L-carnitine on lipid profiles in hemodialysis patients. Data extraction and quality assessment were performed, focusing on primary outcomes, including changes in triglycerides (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low-density lipoprotein (VLDL), and secondary outcomes including blood pressure (BP) and body mass index (BMI). Results A total of 28 RCTs were eligible for the current systematic review, including 1,340 hemodialysis patients (671 intervention, 669 control). There were no significant differences in the mean change of TG (SMD: -0.006; 95% CI, -0.272 to 0.259; P = 0.95), TC (SMD: -0.086; 95% CI, -0.253 to -0.079; P = 0.29), HDL (SMD: 0.060; 95% CI, -0.057 to 0.177; P = 0.29), LDL (SMD: -0.075; 95% CI, -0.274 to 0.123; P = 0.43), VLDL (SMD: -0.064; 95% CI, -0.272 to 0.142; P = 0.51), BMI (SMD: -0.025; 95% CI, -0.139 to 0.088; P = 0.56), systolic BP (SMD: 0.055; 95% CI, -0.110 to 0.220; P = 0.43), and diastolic BP (SMD: -0.028; 95% CI, 0.156 to 0.099; P = 0.56). The same insignificant findings were observed after conducting a subgroup analysis based on the route of administration (intravenous vs. Oral). Conclusion L-carnitine supplementation does not significantly change and improve the serum lipid profile, including TG, TC, HDL, LDL, and VLDL levels. Additionally, it has no notable effects on BMI, systolic, or diastolic BP.

Abstract
Cytoreductive Surgery (CRS) and Hyperthermic Intraperitoneal Chemotherapy (HIPEC) are a pair of relatively modern therapeutic surgical methods in advanced cancerous patients with peritoneal metastasis (PM). The goal of CRS + HIPEC is treatment or to improve survival outcomes, which are linked to high morbidity side effects and complications, even with their possible advantages. Surgical-related, chemotherapy-related, anesthetic-related, gastrointestinal, organs and systemic complications are the categories into which complications are separated according to frequency, risk factors, and effect on patient outcomes. In this narrative review of the literature, the side effects and complications of HIPEC + CRS in cancer patients with PM are examined. The present knowledge on the incidence, frequency, kinds, and risk factors of acute complications following CRS + HIPEC is summarized in this study. This review emphasizes the need for careful patient selection criteria, precise surgical technique, and thorough intraoperative care to reduce or manage these risks. Moreover, it highlights the need for interdisciplinary collaboration in treating these patients. This study aims to know these complications, improve clinical practice, and guide future studies to increase the safety and efficacy of CRS + HIPEC in treating metastatic colorectal cancer.

Hoveidaei AH, Karimi M, Niakan R, Khadembashiri MA, Khadembashiri MM, Suresh SJ, LaPorte DM. Impact of Program Characteristics on Diversity Representation in Orthopaedic Surgery Residency Websites. JOURNAL OF SURGICAL EDUCATION 2024; 81:103289. [PMID: 39426316 DOI: 10.1016/j.jsurg.2024.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2024] [Revised: 09/01/2024] [Accepted: 09/14/2024] [Indexed: 10/21/2024]
Abstract
OBJECTIVES To examine how residency program characteristics, including program type, city population, region, program director/chair sex and ethnicity, and program size, influence the representation of diversity elements on orthopaedic surgery residency program websites. DESIGN Cross-sectional study. SETTING Orthopaedic surgery residency programs in the United States. PARTICIPANTS A total of 199 active nonmilitary orthopaedic surgery residency programs listed on the Electronic Residency Application Service (ERAS) and National Resident Matching Program (NRMP) directories in May 2023, with 198 programs included in the final analysis. RESULTS The analysis of 198 programs showed an average of 4.32 ± 1.75 diversity elements per website. Large programs and university-affiliated programs were significantly more likely to feature 4 or more diversity elements (p < 0.001). Mississippi, New Hampshire, and Rhode Island had the highest mean diversity scores. The most common diversity elements were individual photographs of residents (87.37%) and faculty (81.82%), while the least common were community resources (24.24%) and nondiscrimination statements (13.64%). Program size and affiliation had significant associations with diversity representation, whereas the sex and ethnicity of program directors and chairs did not. CONCLUSIONS The study reveals that program size and affiliation significantly influence the presence of diversity elements on orthopaedic surgery residency program websites. It also underscores the urgent need for smaller and non-university programs to enhance their diversity and inclusion efforts. The findings suggest that other factors beyond leadership characteristics affect diversity representation. Improving nondiscrimination statements and DEI messages on websites could further support diversity in orthopaedic surgery residency programs.

Abstract
BACKGROUND Anti-N-methyl-D-aspartate receptor encephalitis is a sporadic autoimmune disorder of the brain that presents in a variety of neuropsychiatric manifestations, including seizures, psychosis, and alterations in behavior. N-methyl-D-aspartate receptor is primarily seen in young females. Although this disease can be treated, it can relapse in rare cases. Relapsing typically occurs within the early years following the initial episode and is exceedingly rare after 5 years. CASE PRESENTATION In this case study, we report on a 16-year-old Iranian female experiencing a relapse of anti-N-methyl-D-aspartate receptor encephalitis 8 years after her initial diagnosis. She was admitted to the hospital with dysphasia (a speech disorder) and dyslexia (reading and writing impairment). A thorough clinical evaluation revealed the presence of anti-glutamate receptor type N-methyl-D-aspartate receptor antibodies in her serum and cerebrospinal fluid, confirming the diagnosis. Following treatment with immunotherapy and plasmapheresis, she made a complete recovery. CONCLUSION This case of relapsing anti-N-methyl-D-aspartate receptor encephalitis, occurring more than 5 years after the initial episode, is exceptionally rare. This late relapse underscores the importance of long-term follow-up for patients with this condition.

BMC Anesthesiol 2024; 24:431. [PMID: 39592945 PMCID: PMC11600835 DOI: 10.1186/s12871-024-02820-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2024] [Accepted: 11/18/2024] [Indexed: 11/28/2024] Open
Abstract
BACKGROUND Muscle relaxants are used during surgery, but their impact on ECG may differ, potentially affecting cardiac safety. This study aimed to compare the effects of Atracurium versus Cisatracurium on QT interval changes in patients undergoing cataract surgery. METHOD This double-blind, parallel-group randomized clinical trial (RCT) was conducted in 2023 in Hamadan, Iran. A total of 80 patients undergoing cataract surgery under general anesthesia were randomly assigned to receive either Atracurium (n = 40) or Cisatracurium (n = 40). QT interval changes were measured at four time points to assess and compare the corrected QT interval (QTc) between the two groups. Data were analyzed using SPSS version 29, and a p-value < 0.05 was deemed significant. RESULTS Cisatracurium demonstrated significant reductions in QTc from pre-anesthesia to post-anesthesia and through recovery, with values of -9.325 ms (P = 0.045), -9.925 ms (P = 0.038), and - 19.359 ms (P = 0.016), respectively. Atracurium also showed reductions but a notable increase in QTc after anesthesia to the end of surgery (32.322 ms, P = 0.0019). Throughout the procedure, Cisatracurium maintained shorter QTc intervals compared to Atracurium (e.g., T0: 420.07 ms vs. 434.75 ms, P = 0.03), but post-recovery, no significant differences were observed (Cisatracurium: 440.05 ms; Atracurium: 439.80 ms, P = 0.489). CONCLUSIONS Atracurium causes more QT prolongation than Cisatracurium. While both affect QTc intervals, Cisatracurium has a more stable impact on cardiac repolarization, making it safer for patients at risk of QT prolongation. Cisatracurium's minimal impact on cardiovascular function, especially in patients with low ejection fraction, makes it the preferred choice for maintaining cardiac stability.

Abstract
Rhabdomyolysis (RML), characterized by the breakdown of skeletal muscle fibers and the release of muscle contents into the bloodstream, has emerged as a notable complication associated with Coronavirus disease 2019 (COVID-19) infection and vaccination. Studies have reported an increased incidence of RML in individuals with severe COVID-19 infection. However, the exact mechanisms remain unclear and are believed to involve the host's immune response to the virus. Furthermore, RML has been documented as a rare adverse event following COVID-19 vaccination, particularly with mRNA vaccines. Proposed mechanisms include immune responses triggered by the vaccine and T-cell activation against viral spike proteins. This study aims to review the current literature on the incidence, pathophysiology, clinical presentation, and outcomes of RML secondary to COVID-19 infection and vaccination. We identify common risk factors and mechanisms underlying this condition by analyzing case reports, clinical studies, and pharmacovigilance data. Our findings suggest that while RML is a relatively rare adverse event, it warrants attention due to its potential severity and the widespread prevalence of COVID-19 and its vaccines. This review underscores the need for heightened clinical awareness and further research to optimize management strategies and improve patient outcomes in this context.

Abstract
BACKGROUND Tracheal diverticulum is a rare condition often linked to other malformations. This case study highlights the posterior tracheal diverticulum, covering its causes, symptoms, diagnosis, treatment, and prognosis. The report is significant due to the rarity of tracheal diverticulum and potential for misdiagnosis, which can result in complications such as respiratory infections. The case offers novel insights into the presentation and management of tracheal diverticulum, helping to guide future diagnosis and treatment. CASE PRESENTATION A 73-year-old Iranian man with a history of cardiac surgery 15 years ago was admitted to the Loghman Hakim Hospital in Tehran, Iran, for retrosternal chest pain, shoulder radiation, and a persistent cough lasting 4 months. The patient underwent cardiac tests and a lung computed tomography scan, which showed a 16 × 18 mm air-filled outpouching connected to the trachea's right posterolateral side, leading to a diagnosis of tracheal diverticulum. The patient was treated with bronchodilators and antibiotics. CONCLUSIONS Tracheal diverticulum is typically asymptomatic but can present with respiratory difficulties, dysphagia, and hoarseness. Diagnosis relies on imaging, and treatment ranges from conservative management to surgical intervention, particularly in symptomatic cases or those with complications. Recognizing tracheal diverticulum in surgical and anesthesia planning is crucial to prevent severe risks such as airway obstruction or trauma. This case report highlights the importance of early detection and personalized management, potentially improving patient outcomes and guiding clinical decision-making in similar cases.

Abstract
Background Type 2 diabetes mellitus (T2DM) is a significant global health challenge whose prevalence is projected to increase alarmingly. Recently, due to better safety and fewer adverse effects, herbal medicines have been used to manage T2DM. This study aimed to evaluate the efficacy of boswellia in improving glycemic markers and lipid profiles in T2DM patients. Methods A comprehensive search was conducted on the PubMed, Web of Science, and Scopus databases for all relevant studies published up to April 30, 2024. The effects of boswellia supplementation were evaluated using glycemic markers and lipid profiles. The data were extracted and meta-analyzed using Stata software. Results This meta-analysis included five studies with a total of 287 patients with T2DM. It was found that boswellia in patients with T2DM compared to the placebo or control group significantly reduced hemoglobin A1C (HbA1C) (SMD: -1.01; 95%CI: -1.55 to -0.46; P=0.00), total cholesterol (TC) (SMD: -0.44; 95%CI: -0.68 to -0.21; P=0.00), Triglycerides (TG) (SMD: -0.42; 95%CI: -0.66 to -0.19); P=0.00) and low-density lipoprotein (LDL) (SMD: -0.43; 95%CI: -0.73 to -0.12); P=0.006) levels, while reduced fasting blood glucose (FBG) but it was not significant (SMD: -1.34, 95%CI: -2.68 to 0.00; P=0.05). Notably, it did not affect high-density lipoprotein (HDL) (SMD: 0.56, 95%CI: -0.14 to -1.26; P=0.118). Conclusion In summary, boswellia supplementation has the potential to improve glycemic markers and lipid profiles in patients with T2DM. It may help diabetic patients in addition to a controlled diet and other treatments.

Abstract
Background and objectives Direct-acting antiviral (DAA) agents are now widely used to treat patients with hepatitis C infection (HCV) and effectively increase their sustained virologic response (SVR). However, the literature seems to lack or deficient evidence of DAA efficacy in more complicated patients, especially those with HCV reinfection after liver transplantation (LT) or liver-kidney (hepatorenal) transplantation (LKT). This study aimed to retrospectively evaluate the effectiveness of two different DAA regimens in LT and LKT patients with HCV reinfection. Methods This cross-sectional study was conducted at three hospitals in Tehran, Iran, from 2014 to 2020, enrolling 53 patients with recurrent HCV infection after LT (n = 35) or LKT (n = 18). Patients were treated for 12 weeks with one of two DAA regimens: 37 patients (70%) received Daclatasvir and Sofosbuvir (SOF + DCV), while 16 patients (30%) received Sofosbuvir and Ledipasvir (SOF + LDV). Ribavirin (RBV) was added as an adjunct antiviral in 28 patients (52.8%). To assess the SVR, all patients were followed for 12 weeks after treatment. Results Both DAA regimens were well-tolerated and effective, with 94.6% (35 of 37) achieving SVR-12 in the SOF + DCV group and 93.8% (15 of 16) in the SOF + LDV group. Additionally, SVR-12 rates were promising across treatment durations, with 93.9% (31 of 33) in the 12-week group and 95% (19 of 20) in the 24-week group achieving undetectable HCV RNA. No significant difference in SVR was observed between the two regimens (p = 0.439). Conclusion The DAA-based therapeutic regimen was well tolerated and showed significant effectiveness in achieving the virologic response in patients with HCV reinfection after LT or LKT.

JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2024; 43:154. [PMID: 39342393 PMCID: PMC11439322 DOI: 10.1186/s41043-024-00645-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/09/2024] [Accepted: 09/13/2024] [Indexed: 10/01/2024]
Abstract
BACKGROUND Erectile dysfunction (ED) is a common condition with various contributing factors, including lifestyle and dietary habits. Caffeine, a widely consumed stimulant, has been linked to multiple physiological effects on vascular function and hormonal balance that might influence sexual function. This meta-analysis aims to evaluate the association between caffeine intake and the risk of ED by analyzing data from cohort studies. METHODS A systematic search was conducted across PubMed, Web of Science, Scopus, and Embase databases, and a manual search was conducted on Google Scholar for studies on the relationship between caffeine intake and ED in adult men. The search included observational studies published up to April 1, 2024. Four cohort studies were included, and their data were extracted and analyzed by STATA version 18. RESULTS Four included cohort studies comprised 51,665 cohort members. The study population included adult males, on average, aged 18 to 80. The results indicate that there was no significant relationship between coffee consumption and the risk of ED (relative risk [RR] = 0.94, 95% CI: 0.86-1.03; p = 0.999). CONCLUSIONS The current evidence suggests no significant relationship between caffeine intake and ED, but limited studies limit conclusions. Future research should focus on larger sample sizes, standardized outcome assessments, and different dosages and forms of caffeine consumption.

Abstract
The human gastrointestinal (GI) tract microbiome is a complex and all-encompassing ecological system of trillions of microorganisms. It plays a vital role in digestion, disease prevention, and overall health. When this delicate balance is disrupted, it can lead to various health issues. Fecal microbiota transplantation (FMT) is an emerging therapeutic intervention used as an adjuvant therapy for many diseases, particularly those with dysbiosis as their underlying cause. Its goal is to restore this balance by transferring fecal material from healthy donors to the recipients. FMT has an impressive reported cure rate between 80% and 90% and has become a favored treatment for many diseases. While FMT may have generally mild to moderate transient adverse effects, rare severe complications underscore the importance of rigorous donor screening and standardized administration. FMT has enormous potential as a practical therapeutic approach; however, additional research is required to further determine its potential for clinical utilization, as well as its safety and efficiency in different patient populations. This comprehensive literature review offers increased confidence in the safety and effectiveness of FMT for several diseases affecting the intestines and other systems, including diabetes, obesity, inflammatory and autoimmune illness, and other conditions.

Abstract
Bone metastases (BM) are a common complication in advanced cancer patients, significantly contributing to morbidity and mortality due to their ability to cause pain, fractures, and spinal cord compression. Radiation therapy (RT) is vital in managing these complications by targeting metastatic lesions to ease pain, improve mobility, and reduce the risk of skeletal-related events such as fractures. Evidence supports the effectiveness of RT in pain relief, showing its ability to provide significant palliation and lessen the need for opioid painkillers, thereby enhancing the overall quality of life (QoL) for patients with BM. However, optimizing RT outcomes involves considerations such as the choice of radiation technique, dose fractionation schedules, and the integration of supportive care measures to mitigate treatment-related side effects like fatigue and skin reactions. These factors highlight the importance of personalized treatment planning tailored to individual patient needs and tumor characteristics. This mini-review aims to provide comprehensive insights into the multifaceted impacts of RT on pain management and QoL enhancement in BM patients, with implications for refining clinical practices and advancing patient care through the synthesis of findings from various studies.

Effects of chia seed (Salvia hispanica L.) supplementation on cardiometabolic health in overweight subjects: a systematic review and meta-analysis of RCTs. Nutr Metab (Lond) 2024; 21:74. [PMID: 39285289 PMCID: PMC11406937 DOI: 10.1186/s12986-024-00847-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2024] [Accepted: 08/26/2024] [Indexed: 09/19/2024] Open
Abstract
BACKGROUND Obesity is a significant public health issue associated with various chronic diseases. Research has indicated that chia seeds have the potential to improve cardiometabolic health. However, due to the diversity of research and inconsistencies in study design, further investigation is needed to fully understand their clinical effects on overweight individuals. This review aims to comprehensively analyze the available evidence on the effects of chia seeds on cardiometabolic indices in overweight populations through a meta-analysis. METHODS A comprehensive literature search was performed across PubMed, Web of Science, Scopus, and Embase databases from their inception until 01-03-2024 to identify randomized controlled trials (RCTs) evaluating the effect of chia on cardiometabolic indices in overweight subjects. The search strategy incorporated both Medical Subject Headings (MeSH). Following the screening, ten RCTs were finally included. The data, including subject characteristics, study design, and changes in serum biomarkers, were extracted and analyzed using Stata software version 18. RESULTS The meta-analysis results reveal that chia supplementation no significant changes in lipid profile, including triglycerides (TG) (MD: - 5.80 mg/dL, p = 0.47), total cholesterol (TC) (MD: - 0.29 mg/dL, p = 0.95), high-density lipoprotein (HDL) (MD: 1.53 mg/dL, p = 0.33), and low-density lipoprotein (LDL) (MD: 0.63 mg/dL, p = 0.88). Similarity fasting blood glucose (FBG) (MD: - 0.03 mg/dL, p = 0.98), hemoglobin A1c (HbA1c) (MD: - 0.13%, p = 0.13), and insulin levels (MD: 0.45 µIU/mL, p = 0.78). However, chia seed supplementation was associated with a significant reduction in C-reactive protein (CRP) (MD: - 1.18 mg/L, p < 0.0001), but no significant changes were observed in interleukin-6 (IL-6) (MD: - 0.15, p = 0.70) or tumor necrosis factor-alpha (TNF-α) (MD: 0.03, p = 0.91). There was no significant effect on body mass index (BMI) (MD: 0.1 kg/m2, p = 0.91), but a significant reduction in waist circumference (WC) (MD: - 2.82 cm, p < 0.001) was noted. Additionally, chia seed supplementation resulted in a significant reduction in systolic blood pressure (BP) (MD: - 3.27 mmHg, p = 0.03), though diastolic BP changes were non-significant (MD: - 2.69 mmHg, p = 0.09). The studies showed low to moderate heterogeneity in outcome measures, with I2 < 50%. CONCLUSION Chia seed supplementation does not significantly impact most lipid profile parameters and glycemic markers. However, it shows potential benefits in reducing WC, BP, and CRP. While chia seeds can be a valuable addition to cardiometabolic health management, they should be part of a broader health strategy that includes a balanced diet, exercise, and lifestyle modifications for optimal results.

Abstract
In this study, we explored the intricate relationship between Pannexin 1 (PANX1) and the Hippo signaling pathway effector, Yes-associated protein (YAP). Analysis of The Cancer Genome Atlas (TCGA) data revealed a significant positive correlation between PANX1 mRNA and core Hippo components, YAP, TAZ, and Hippo scaffold, IQGAP1, in invasive cutaneous melanoma and breast carcinoma. Furthermore, we demonstrated that PANX1 expression is upregulated in invasive melanoma cell lines and is associated with increased YAP protein levels. Notably, our investigations uncovered a previously unrecognized interaction between endogenous PANX1 and the Hippo scaffold protein IQGAP1 in melanoma cells. Moreover, our findings revealed that IQGAP1 exhibits differential expression in melanoma cells and plays a regulatory role in cellular morphology. Functional studies involving PANX1 knockdown provided compelling evidence that PANX1 modulates YAP protein levels and its co-transcriptional activity in both melanoma and breast carcinoma cells. Importantly, our study showcases the potential therapeutic relevance of targeting PANX1, as pharmacological inhibition of PANX1 using selective FDA-approved inhibitors or PANX1 knockdown reduced YAP abundance in melanoma cells. Furthermore, our Clariom™ S analysis unveiled key genes implicated in cell proliferation, such as neuroglin1 (NRG1), β-galactoside binding protein, galectin-3 (LGALS3), that are affected in PANX1-deficient cells. In summary, our investigation delves into the intricate interplay between PANX1 and YAP in the context of invasive melanoma, offering valuable insights into potential therapeutic strategies for effective treatment.

Abstract
Pregnancy as a sensitive period has a critical effect on the mother and infant's life. It is well understood that dietary habits and mother awareness can improve health status and prevent pregnancy complications such as gestational diabetes, pre-eclampsia, and nausea and vomiting. The current study was conducted to investigate the association between dietary habits and self-care behaviors with pregnancy complications. This cross-sectional study was conducted across 300 pregnant women in their third trimester referred to healthcare centers and Yas hospital in Tehran, Iran. Dietary habits and self-care behaviors were assessed by valid and reliable questionnaires. Dietary intake and physical activity were evaluated using valid and reliable Food Frequency Questionnaires and Pregnancy Physical Activity questionnaires, respectively. Women with self-care behaviors had a lower rate of pre-eclampsia (P = 0.9). Regarding food habits, pregnant women who ate their meals faster had a non-significantly higher rate of gestational diabetes and pre-eclampsia. Pregnant women who consumed red meat on a daily frequency had a significantly higher rate of nausea and vomiting (OR 1.85; 95% CI 1.05-3.28, P = 0.03). Also, there was a significant positive association between the mother's pre-pregnancy BMI and gestational diabetes and pre-eclampsia [(OR 2.03; 95% CI 1.03-3.98, P = 0.03) and (OR 4.23; 95% CI 1.12-16.0, P = 0.03) respectively]. There was no significant association between pregnant women's dietary habits and GDM and pre-eclampsia. However, pregnant women with pre-pregnancy overweight and obesity had increased odds of gestational diabetes and pre-eclampsia significantly.

Abstract
Introduction Various treatment protocols have been recommended since the beginning of the COVID-19 pandemic and have gradually evolved. This study aimed to assess the effectiveness and safety of incentive spirometer exercise (ISE) in outcomes of hospitalized patients with moderate-to-severe COVID-19 pneumonia. Methods A 3-month single-blind, two parallel-armed randomized controlled trial was conducted at Imam Hossein Hospital, Tehran, Iran. Participants aged >18 years with documented COVID-19 pneumonia were randomly allocated to 2 groups of IS (ISE in addition to the usual treatment) and control (usual care alone). The IS group was also asked to perform ISE after discharge for three months. The primary outcomes were peripheral O2 saturation (SpO2), VBG parameters (pCO2, PH, HCO3), dyspnea level measured by Modified Borg Scale (MBS), length of hospital stay (LOS), and respiratory rate (RR). Secondary outcomes included mortality rate, intubation rate (IR), and ICU admission rate. Results A total of 160 eligible patients were randomly assigned to either the IS (n = 80) or control (n=80) groups. Although there were no significant differences in primary and secondary outcomes between the groups post-intervention, adjusted analysis showed that participants allocated to the IS group had significantly higher SpO2 levels and lower RR, MBS levels, and LOS. Also, the adjusted model analysis showed a marginal statistically significant difference between groups in secondary outcomes, such as IR, the 1-month mortality rate, and the 3-month mortality rate. Conclusion It seems that adding the ISE to usual care in the early treatment setting of COVID-19 patients resulted in a relatively significant increase in SpO2 levels, improved respiratory status, and marginally decreased LOS. Additionally, ISE minimally reduced ICU admissions and intubation rates, with no significant impact on in-hospital or long-term mortality in patients with COVID-19 pneumonia.

Abstract
BACKGROUND Given the limited specificity of D-dimer, there is a perceived need to discover a more precise marker for diagnosing individuals who are suspected of having pulmonary embolism (PE). In this study, by evaluating the increase in the serum level of Apelin-13 and D-dimer, we found valuable findings about Apelin-13, which can be suggested as an auxiliary and non-invasive diagnostic biomarker in individuals with suspected PE, based on the obtained results. METHODS In this case-control study, 52 Iranian individuals were included, all of whom were suspected to have PE. These individuals were then divided into two groups based on the results of CT angiography, which is considered the gold standard imaging method for diagnosing PE. The two groups were patients with PE and patients without PE. Finally, the levels of certain markers in the serum were compared between the two groups. RESULTS The mean serum D-dimer levels in patients with PE were significantly elevated (p < 0.001) in comparison to those without PE (1102.47 to 456.2 ng/ml). Furthermore, the mean level of Apelin-13 was significantly higher in patients with PE (49.8 to 73.11 ng/L) (p < 0.001). The cutoff point of Apelin-13 has been calculated at 58.50 ng/ml, with 90.9% sensitivity and 90% specificity. The D-dimer cutoff point was 500 ng/ml, with 95.5% sensitivity and 43.3% specificity. CONCLUSIONS Based on the results of this study, the serum level of Apelin-13 can be used as a novel diagnostic and screening biomarker in patients with pulmonary thromboembolism.

Abstract
Dietary diabetes risk reduction score (DDRRs) is inversely associated with a lower risk of type 2 diabetes. Given the importance of the association between body fat and insulin resistance and the effect of diet on these parameters, this study aimed to investigate the association between DDRRS and body composition parameters, including the visceral adiposity index (VAI), lipid accumulation product (LAP), and skeletal muscle mass (SMM). This study was conducted on 291 overweight and obese women aged 18-48 years old recruited from 20 Tehran Health Centers in 2018. The anthropometric indices, biochemical parameters, and body composition were measured. A semi-quantitative food frequency questionnaire (FFQ) was used to calculate DDRRs. Linear regression analysis was used to examine the association between DDRRs and body composition indicators. The mean (SD) age of participants was 36.67 (9.10) years. After adjustment for potential confounders, VAI (β = 0.27, 95% CI = - 0.73, 1.27, Ptrend = 0.052), LAP (β = 8.14, 95% CI = - 10.54, 26.82, Ptrend = 0.069), TF (β = - 1.41, 95% CI = 11.45, 17.30, Ptrend = 0.027), trunk fat percent (TF%) (β = - 21.55, 95% CI = - 44.51, 1.61, Ptrend = 0.074), body fat mass (BFM) (β = - 3.26, 95% CI = - 6.08, - 0.44, Ptrend = 0.026), visceral fat area (VFA) (β = - 45.75, 95% CI = - 86.10, - 5.41, Ptrend = 0.026), waist-to-hip ratio (WHtR) (β = - 0.014, 95% CI = - 0.031, 0.004, Ptrend = 0.066), visceral fat level (VFL) (β = - 0.38, 95% CI = - 5.89, 5.12, Ptrend = 0.064), fat mass index (FMI) (β = - 1.15, 95% CI = - 2.28, - 0.02, Ptrend = 0.048) decreased significantly over tertiles of DDRRs, and also there was no significant association between SMM and DDRRs tertiles (β = - 0.57, 95% CI = - 1.69, 0.53, Ptrend = 0.322). The findings of this study demonstrated that participants with higher adherence to the DDRRs had lower VAI (β = 0.78 vs 0.27) and LAP (β = 20.73 vs 8.14). However, there was no significant association between DDRRs and VAI, LAP and SMM, which are mentioned as the primary outcomes. Future studies with larger sample of both genders are needed to investigate our findings.

ENVIRONMENTAL RESEARCH 2023; 222:115321.

Abstract
The first ultrasonic synthesis of [Cu(L)4(SCN)2] (L = 1-methylimidazole) nanocomplex was carried out under ultrasonic irradiation, and its photocatalytic performance for the degradation of remdesivir (RS) under sunlight irradiation was comprehensively investigated for the first time in this study. The physicochemical properties of the synthesized photocatalyst were examined by Fourier-transform infrared (FT-IR), field emission scanning electron microscopy (FE-SEM), diffuse reflectance spectroscopy (DRS), and thermogravimetric analysis (TGA) techniques. The band gap of the synthesized [Cu(L)4(SCN)2] nanocomplex was determined to be 2.60 eV by the diffuse reflectance spectroscopy method using Kubelka-Munk formula. The photocatalytic performance of nanocomplex was examined for the removal of remdesivir under sunlight from water for which the results indicated that an amount of 0.5 gL-1 of the [Cu(L)4(SCN)2] nanocomplex was sufficient to remove more than 96% remdesivir from its 2 mg L-1 concentration within 20 min, at pH = 6. The kinetic data showed that the photodegradation onto the [Cu(L)4(SCN)2] nanocomplex has a high correlation (0.98) with the pseudo-second-order kinetic model. The decrease in chemical oxygen demand (COD) (from 70.5 mg L-1 to 36.4 mg L-1) under optimal conditions clearly confirmed the mineralization of the RS drug. The values of ΔS° (-0.131 kJ mol-1 K-1) and ΔH° (-49.750 kJ mol-1) were negative, indicating that the adsorption process was spontaneous and more favorable in lower temperatures. Moreover, the RS structure in the open shell state and the high HOMO and LUMO gaps based on the M06/6-31 + G (d) level of theory may be a confirmation of this fact. In addition, the Hirshfeld surface analysis (HSA) of the crystal packing of the prepared complex was discussed in detail to evaluate the interactions between the crystal packings. The results of this study confirm that the [Cu(L)4(SCN)2] nanocomplex can be successfully used for the photodegradation of pharmaceutical contaminants.

Abstract
The channel-forming glycoprotein Pannexin 3 (PANX3) functions in cutaneous wound healing and keratinocyte differentiation, but its role in skin homeostasis through aging is not yet understood. We found that PANX3 is absent in newborn skin but becomes upregulated with age. We characterized the skin of global Panx3 knockout mice (KO) and found that KO dorsal skin showed sex-differences at different ages, but generally had reduced dermal and hypodermal areas compared to aged-matched controls. Transcriptomic analysis of KO epidermis revealed reduced E-cadherin stabilization and Wnt signaling compared to WT, consistent with the inability of primary KO keratinocytes to adhere in culture, and diminished epidermal barrier function in KO mice. We also observed increased inflammatory signaling in KO epidermis and higher incidence of dermatitis in aged KO mice compared to wildtype controls. These findings suggest that during skin aging, PANX3 is critical in the maintenance of dorsal skin architecture, keratinocyte cell-cell and cell-matrix adhesion and inflammatory skin responses.

Abstract
BACKGROUND The association between different dietary approaches and quality of life (QoL) has been well-demonstrated in previous research. However, the relationship between glycemic index (GI) and glycemic load (GL) with different dimensions of QoL has not been established. Therefore, we aimed to investigate the relationship between GI and GL with QoL in overweight and obese women. METHODS Two hundred seventy-six overweight and obese women (body mass index (BMI) ≥ 30 kg/m2), aged 18-64 years old, were included in this cross-sectional study. The amount of dietary intake and GI and GL indexes were established using a valid and reliable Food Frequency Questionnaire (FFQ) containing 147 items. Body composition (using bioimpedance analysis), anthropometrics, and physical activity were assessed. Insulin resistance (HOMA-IR) and hs-CRP were also measured, whilst QoL was measured using the SF-36 (short-form-36), self-administered, questionnaire. RESULT Analyses were performed using multivariable linear regression, considering a wide range of confounding variables, such as age, physical activity, BMI, education, job, smoking, and marriage. We found a significant negative association between glycemic load and quality of life (β = -0.07, 95%CI = -0.13_ -0.01, p = 0.01). No significant associations were observed between glycemic index and quality of life (β = -0.03, 95%CI = -0.81_ 0.75, p = 0.93). CONCLUSION We observed a significant negative association between QoL and GL, but not GI, among overweight and obese women in Iran. Our results need to be confirmed with further well-designed and adequately powered studies that control for clinical confounders.
