Thromboembolism during immune checkpoint inhibitor therapy: frequency and risk factors.

BACKGROUND: Thromboembolism (TE) is a well-known complication during chemotherapy in cancer patients. However, the risk of TE associated with immune checkpoint inhibitors (ICIs) is unknown. This study was performed to investigate the incidence of TE and associated risk factors in patients treated with ICIs. METHODS: We conducted a retrospective chart survey of patients receiving at least one ICI at Shinshu University Hospital between September 2014 and October 2021. Age, sex, cancer type, body mass index, medical history, laboratory data at commencement of treatment, and medication data were obtained from electronic medical records. TE events (venous thromboembolism [VTE], arterial thromboembolism [ATE]) were identified after ICI initiation. RESULTS: The study population consisted of 548 patients with a median age of 70.0 (19-89) years, 71.4% men, and a median follow-up of 15.1 months (range; 0.16-72.0 months). Nivolumab was the most commonly used ICI (45.8%), followed by pembrolizumab (23.9%), pembrolizumab plus anticancer drugs (7.8%), and nivolumab plus ipilimumab (5.1%). Thirty-eight cases of TE (6.9%) occurred (22 VTE, 16 ATE). Risk factors significantly associated with TE in multivariate logistic analysis were dyslipidemia (OR 2.44; 95% CI 1.17-5.09; p = 0.017), Khorana score ≥ 2 (HR 2.40; 95% CI 1.14-5.04; p = 0.021). Overall survival was not significantly different from patients without TE (p = 0.963). CONCLUSION: These results suggested that the frequency of TE is higher than expected and should be considered and monitored in patients treated with ICIs.

Gender differences in cardiac rehabilitation participation and outcomes: an 18-year retrospective study in Iran.

BACKGROUND: Cardiac rehabilitation (CR) is crucial for addressing cardiovascular diseases globally, with a specific emphasis on gender differences. Despite its demonstrated benefits for women, there's limited acceptance globally, especially in low- and middle-income countries. The program aims to optimize risk factors and improve overall patient well-being. METHODS: A cohort study was performed on those who were candidates for CR programs during 2001-2019. Assessments were performed within one week before and one week after the 8-week CR program. Age, sex, smoking status, clinical data, resting systolic and diastolic blood pressure (SBP and DBP, respectively), echocardiography and laboratory data were obtained. Functional capacity was evaluated using the international physical activity questionnaire, and a treadmill exercise test. Anxiety, depression, general quality of life (QoL), and health-related QoL were selected for psychological status. Then statistical analysis was performed on data. RESULT: In this study, the number of male patients was 1526 (73.69%). The average age of patients in the female group was higher than that of males (58.66 ± 9.08 vs. 56.18 ± 9.94), according to the crude model results, the changes in emotional, social and physical scores were significant (P-value:0.028, 0.018, 0.030), as well as the differences in Mets and smoking were significant (P-value for both < 0.001) in the adjusted model, the emotional variables and Mets changes were significant in two groups, so that the emotional score in the female group was higher than that of the male group, and the female Mets score was significantly lower than that of the male group. CONCLUSION: The CR program can improve cardiovascular outcomes, but the greatest impact was on the quality of life, patient METs and smoking behavers. Also the number of female participants in the CR program was less than the number of males.

Risk Factors for Musculoskeletal Health: A Review of the Literature and Clinical Application.

Context: Musculoskeletal disorders (MSKD) are currently the leading contributor to disability worldwide. Unlike other prevalent and disabling healthcare conditions such as CVD, risk factors associated with MSKD are not commonly discussed or integrated into current medical practice, rehabilitation practice or wellness programs. The primary purpose of this review is to describe the known risk factors most closely associated with MSKD. The secondary purpose is to propose a clinical model to manage MSK health aimed at maximizing the healthy pursuit of a physically active and healthy lifestyle. Evidence acquisition: In this review the most common MSKD risk factors, with a focus on those that can be easily screened in clinical practice are presented. The importance of understanding the magnitude and number of risk factors present as well as the multidimensional nature of MSKD risk is discussed. Results: A total of 11 MSKD risk factors were identified. Most of the risk factors are modifiable, and the evidence associated with modifiability for the most prominent risk factors is reviewed.Researchers have found that often patients are discharged from care with several known MSKD risk factors. In such instances, local pain and dysfunction are managed well, but expanding our rehabilitation care to include comprehensive risk factor management would ultimately benefit the patient and reduce healthcare costs. Conclusion: The most common MSKD risk factors are discussed and a clinical framework to individualize intervention is proposed. Addressing key risk factors within rehabilitation may be an important step to reduce the enormous and growing burden these disorders are having on society. Level of Evidence: 5.

Cigarette Smoking, Mental Health, Depression, Maryland Behavioral Risk Factor Surveillance System Survey, 2020.

Background: Smoking cessation is linked to improved mental health that encompasses the overall well-being and psychological functioning of an individual. Objective: Examine relationships between smoking, mental health, and social connectedness among adults in Maryland, US in 2020. Methodology: This cross-sectional study used data from the Maryland 2020 Behavioral Risk Factor Surveillance System Survey of adults during the onset of COVID-19. Primary outcomes measured include demographics, depression, and number of not good mental health days among individuals with current and former smoking statuses compared to those who have never smoked. Results: Compared to those who never smoked, individuals who currently smoked had an increased relative risk of reporting 14 or more days of not good mental health (RRR = 1.63, 95% CI: 1.35-1.97, P < .001) and a history of depression (RRR = 1.99, 95% CI: 1.69-2.35, P < .001). Individuals with former smoking status also showed elevated risk, with RRR = 1.24 (95% CI: 1.06-1.45, P = .006) for 14 or more days of not good mental health and RRR = 1.46 (95% CI: 1.28-1.66, P < .001) for a history of depression. Widowed, separated, or divorced; unemployed or unable to work; without a high school diploma; or recent physical exam were inclined to have a current or former smoking status. Conclusion: We identify critical subpopulations vulnerable to life-long smoking behaviors amid the COVID-19 pandemic including adults under 35 years old, and those suffering from depression, a lack of social connectedness due to unemployment, changes in marital status, and outdated physical exams. The US Surgeon General's 2023 Advisory on the epidemic of loneliness and the 2021 Youth Mental Health Report emphasize the mental health crises among the young in which these findings serve as a compelling call to action for innovating targeted public health interventions.

Artificial intelligence for predicting mortality in hospitalized COVID-19 patients.

Background: The global demographic situation has been significantly impacted by the COVID-19 pandemic. The objective of this study was to develop a model that predicts the risk of COVID-associated mortality using clinical and laboratory data collected within 72 h of hospital admission. Materials and methods: A total of 3024 subjects with PCR-confirmed COVID-19 were admitted to Almazov National Research Medical Center between May 2020 and August 2021. Among them, 6.25% (n = 189) of patients had a fatal outcome. Five machine learning models and the Boruta-SHAP feature selection method were utilized to assess the risk of mortality during COVID-19 hospitalization. Results: All methods demonstrated high efficacy, with ROC AUC (Receiver Operating Characteristic Area Under the Curve) values exceeding 80%. The selected Boruta-SHAP features, when incorporated into the random forest model, achieved an ROC AUC of 93.1% in the validation. Conclusion: Throughout the study, close collaboration with healthcare professionals ensured that the developed tool met their practical needs. The success of our model validates the potential of machine learning techniques as decision support systems in clinical practice.

Effect of smoking on the risk of gastrointestinal cancer after cholecystectomy: A national population-based cohort study.

BACKGROUND: The role of smoking in the incidence of colorectal cancer (CRC) or gastric cancer (GC) in populations undergoing cholecystectomy has not been investigated. AIM: To evaluate the effect of smoking on CRC or GC development in cholecystectomy patients. METHODS: A total of 174874 patients who underwent cholecystectomy between January 1, 2010 and December 31, 2017 were identified using the Korean National Health Insurance Service claims database. These patients were matched 1:1 with members of a healthy population according to age and sex. CRC or GC risk after cholecystectomy and the association between smoking and CRC or GC risk in cholecystectomy patients were evaluated using adjusted hazard ratios (HRs) and 95%CIs. RESULTS: The risks of CRC (adjusted HR: 1.15; 95%CI: 1.06-1.25; P = 0.0013) and GC (adjusted HR: 1.11; 95%CI: 1.01-1.22; P = 0.0027) were significantly higher in cholecystectomy patients. In the population who underwent cholecystectomy, both CRC and GC risk were higher in those who had smoked compared to those who had never smoked. For both cancers, the risk tended to increase in the order of non-smokers, ex-smokers, and current smokers. In addition, a positive correlation was observed between the amount of smoking and the risks of both CRC and GC. CONCLUSION: Careful follow-up and screening should be performed, focusing on the increased risk of gastrointestinal cancer in the cholecystectomy group, particularly considering the individual smoking habits.

Vitamin D deficiency may increase the risk of acute kidney injury in patients with diabetes and predict a poorer outcome in patients with acute kidney injury.

BACKGOUND: People with diabetes are much more likely to develop acute kidney injury (AKI) than people without diabetes. Low 25-hydroxy-vitamin D [25(OH)D] concentrations increased the risk of AKI in specific populations. Few studies have explored the relationship between the 25(OH)D level and AKI in patients with diabetes. We conducted this study to investigate the relationship between the plasma level of 25(OH)D and the risk of AKI in patients with diabetes, and to evaluate whether the 25(OH)D level could be a good prognostic marker for AKI progression. METHODS: A total of 347 patients with diabetes were retrospectively reviewed. The primary endpoint was the first event of AKI. The secondary endpoint is need-of-dialysis. AKI patients were further followed up for 6 months with the composite endpoint of end-stage renal disease (ESRD) or all-cause death. Kaplan-Meier survival analysis and Cox proportional hazards models were used. RESULTS: During a median follow-up of 12 weeks (12.3 ± 6.7), 105 incident AKI were identified. The middle and high tertiles of baseline 25(OH)D levels were associated with a significantly decreased risk of AKI and dialysis compared to the low tertile group (HR = 0.25, 95% CI 0.14-0.46; HR = 0.24, 95% CI 0.13-0.44, respectively, for AKI; HR = 0.15; 95% CI 0.05-0.46; HR = 0.12; 95% CI 0.03-0.42, respectively, for dialysis). Sensitivity analysis revealed similar trends after excluding participants without history of CKD. Furthermore, AKI patients with 25(OH)D deficiency were associated with a higher risk for ESRD or all-cause death (HR, 4.24; 95% CI, 1.80 to 9.97, P < 0.001). CONCLUSION: A low 25 (OH) vitamin D is associated with a higher risk of AKI and dialysis in patients with diabetes. AKI patients with 25(OH)D deficiency were associated with a higher risk for ESRD or all-cause death.

Construction and validation of a predictive model for the return to work of patients with permanent colorectal stoma: a cross-sectional study.

BACKGROUND: The issue of patients returning to work is increasingly garnering attention from countries worldwide. This study aims to investigate the risk factors associated with patients returning to work after undergoing permanent enterostomies. Additionally, it seeks to establish and validate a nomogram prediction model, thereby providing a more effective reference for patients aiming to return to work. METHODS: This study was a cross-sectional investigation conducted between September 2022 and September 2023. We conveniently selected 293 postoperative patients with permanent colorectal stomas due to colorectal cancer from three tertiary hospitals in Liaoning Province. Participants were categorized into Returned and Non-Returned groups based on their return to work status. Data were collected using a general information questionnaire, a Stoma Acceptance Questionnaire, and the Ostomy Adjustment Inventory. Binary logistic regression analysis was performed using SPSS 25.0 software to identify independent influencing factors. A predictive model was constructed using R Studio 4.3.0 software. Internal validation was conducted through 1,000 rounds of Bootstrap resampling, and model performance was assessed using Receiver Operating Characteristic (ROC) curves, the Hosmer-Lemeshow (H-L) test, and calibration curves. RESULTS: After surgery, the return-to-work rate for patients with permanent colorectal stomas was 29.69%. Age, education level, postoperative time, stoma complication, adjuvant therapy, stoma acceptance score, and ostomy adjustment inventory score were identified as independent factors influencing the return-to-work status of these patients (P < 0.05). These factors were incorporated into a logistic regression model generated by R software, resulting in a ROC curve with an area under the curve (AUC) of 0.916 (95% CI: 0.884-0.947). The Youden index was 0.731, and the cutoff value was 0.228. Sensitivity and specificity were 0.920 and 0.811, respectively. The H-L test demonstrated good model fit (χ2 = 12.858, P = 0.117, P > 0.05). Calibration curves indicated a close alignment between predicted and actual probabilities. CONCLUSIONS: The postoperative return-to-work rate is low in patients with permanent enterostomies. The prediction model developed in this study demonstrates strong performance and offers predictive value, providing a scientific foundation for assessing patients' return to work. Caregivers should prioritize the early identification of various patient types for proactive intervention to enhance the rate of postoperative return to work.

Exploring risk factors for endocrine-related immune-related adverse events: Insights from meta-analysis and Mendelian randomization.

This study utilized meta-analysis and Mendelian randomization (MR) to identify risk factors for endocrine-related immune-related adverse events (EirAEs) and to ascertain whether EirAEs confer better prognosis of immunotherapy. The meta-analysis identified several risk factors for EirAEs, including elevated baseline TSH (OR = 1.30, 95% CI 1.10-1.53), positive TgAb (OR = 14.23, p < .001), positive TPOAb (OR = 3.75, p < .001), prior thyroid-related medical history (OR = 4.19), increased BMI (OR = 1.11), combination immune checkpoint inhibitors (ICIs) therapy with targeted treatment (OR = 2.71, 95% CI 2.11-3.47), and dual ICI therapy (OR = 3.26, 95% CI 2.22-4.79). MR analysis further supported causalities between extreme BMI, hypothyroidism, and irAEs from a genetic perspective. In addition, cancer patients who experienced EirAEs exhibited significantly prolonged PFS (HR = 0.84, 95% CI 0.73-0.97) and OS (HR = 0.59, 95% CI 0.45-0.76) compared to those without. These findings provide valuable insights for clinical decision-making among healthcare professionals and offer direction for future research in this field.

Risk Factors of Cytomegalovirus Retinitis Occurrence After Allogeneic Hematopoietic Stem Cell Transplantation.

PURPOSE: To explore the potential risk factors for the occurrence of human cytomegalovirus (HCMV) retinitis (CMVR) in allogeneic hematopoietic stem cell transplantation (allo-HSCT) patients. METHODS: This is a retrospective, nested case-control study conducted in hematological patients with CMVR who underwent allo-HSCT. Patients diagnosed with CMVR after allo-HSCT were included as the case group, and those without CMVR were matched by a ratio of 1:2 and were recruited as controls. We selected 19 pre- and post-transplant indicators for univariate analysis between the cases and controls, and then Logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence intervals (CI) for exploration of risk factors of the CMVR occurrence. RESULTS: A total of 1308 allo-HSCT patients from January 1, 2020 to July 31, 2023 were analyzed, and 27 patients were diagnosed CMVR with a median onset time of 222 days after transplantation. In univariate analysis, donors of stem cells source, HLA-match types (including matched sibling donor, haploidentical donor, and unrelated donor), post-transplant Epstein-Barr virus (EBV) viremia, platelet implantation time, and serostatus of CMV-IgG were more easily to develop CMVR than controls (p < 0.001, p = 0.003, p < 0.001, p = 0.032, p = 0.038, respectively). Multivariate logistic regression analysis showed that stem cells source (OR 7.823, 95% CI 1.759-34.800), HLA-match types (OR 7.452, 95% CI 1.099-50.542), and post-transplant EBV infection (OR 7.510, 95% CI 1.903-29.640) were positively associated with the onset of CMVR. CONCLUSION: Stem cells derived from bone marrow and peripheral blood, HLA-match types, and post-transplant EBV viremia are important risk predictors of CMVR in allo-HSCT patients. These results suggest that clinicians should pay more attention to these indicators when formulating preventive measures pre- and post-transplant.

Abscesses in different body sites among children: a single-center prospective study.

OBJECTIVES: An abscess is a localized collection of pus contained within a fibrous capsule. In this study, we aimed to determine the demographic pattern, common anatomical sites, risk factors, and the microbial profile of abscesses in different body sites among children. METHODS: We conducted a prospective study in our pediatric surgical department among children with abscesses in different body sites between January 2019 and December 2022. RESULTS: During the study period, 85 children were included. The participant age range was 0 to 14 years old, and 66% of participants were boys. The most common anatomical sites where abscesses formed were the pelvis (n = 29, 34%), abdomen (n = 22, 26%), neck (n = 14, 16%), and extremities (n = 12, 14%). Risk factors of abscesses in different body sites included cannulation, lymphadenitis, mastitis, perforated appendix, and perianal fistula. We observed that 74% of abscesses were of a polymicrobial nature. CONCLUSION: The most common anatomical sites for abscesses in children included the pelvis, abdomen, neck, and extremities. Most abscesses in these sites were polymicrobial in nature.

Incidence and Risk Factors for Lumbar Sympathetic Chain Injury After Oblique Lumbar Interbody Fusion.

OBJECTIVE: Oblique lumbar interbody fusion (OLIF), performed using a retroperitoneal approach, can lead to complications related to the approach, such as lumbar sympathetic chain injury (LSCI). Although LSCI is a common complication of OLIF, its reported incidence varies across studies due to an absence of specific diagnostic criteria. Moreover, research on the risk factors of postoperative sympathetic chain injuries after OLIF remains limited. Therefore, this study aimed to describe the incidence, and identify independent risk factors for LSCI, in patients with degenerative lumbar spinal diseases who underwent OLIF. METHODS: Between October 2020 and August 2023, a retrospective review was conducted at our institute on 200 patients who underwent OLIF at 1 to 4 consecutive spinal levels (L1-5) for degenerative spinal diseases including spinal stenosis, spondylolisthesis, degenerative scoliosis. We excluded those with infections, trauma, tumors, and lower extremity edema/warmth due to other causes. The patients were categorized into 2 groups: those with and without LSCI symptoms. Demographic data, operative data, and pre- and postoperative parameters were evaluated for their association with LSCI using a univariate logistic regression model. Variables with a p-value <0.1 in the univariate analysis were included in a multivariate model to identify the independent risk factors. RESULTS: Thirty-five of 200 patients (17.5%) developed LSCI symptoms after OLIF. Multivariate logistic regression analysis indicated that prolonged retraction time, particularly exceeding 31.5 miniutes, remained an independent risk factor (adjusted odds ratio, 12.59; p<0.001). CONCLUSION: This study demonstrated that prolonged retraction time was an independent risk factor for LSCI following OLIF, particularly when it exceeded 31.5 minutes. Protecting the lumbar sympathetic chain during surgery and minimizing retraction time are crucial to avoiding LSCI following OLIF.

Impact of elevated lipoprotein(a) levels on the functional outcomes of ischemic stroke patients: A systematic review and meta-analysis.

BACKGROUND AND PURPOSE: Elevated serum lipoprotein(a) (Lp[a]) levels have been linked to an increased incidence of stroke. This systematic review and meta-analysis aimed to evaluate the impact of serum Lp(a) on the functional outcomes of patients with ischemic stroke (IS). METHODS: We conducted a comprehensive search of the MEDLINE, Web of Science, Embase, Wanfang, and China National Knowledge Infrastructure databases to identify relevant cohort studies. A random effects model was utilized to synthesize the data, accounting for study heterogeneity. RESULTS: The analysis included 11 cohort studies comprising 11,958 patients with IS. Pooled results indicated that high baseline Lp(a) levels were associated with an increased risk of poor functional outcomes during follow-up (odds ratio [OR] = 2.13, 95% confidence interval = 1.67-2.71, p < 0.001, I2 = 62%). Subgroup analyses revealed that the relationship between high Lp(a) levels and the risk of poor functional outcomes was more pronounced at discharge (OR = 3.25), 3 months (OR = 2.02), and 6 months (OR = 2.11) poststroke, compared to 12 months (OR = 1.25, p for subgroup difference < 0.001). Furthermore, the association was attenuated yet remained significant in studies adjusting for low-density lipoprotein cholesterol (LDL-C) compared to those that did not adjust for LDL-C (OR = 1.69 vs. 2.63, p for subgroup difference = 0.03). CONCLUSIONS: High serum Lp(a) levels at baseline are significantly associated with poor functional outcomes in patients with IS.

Factors associated with anxiety in colorectal cancer survivors: a scoping review.

PURPOSE: Anxiety is one of the most common psychological issues among colorectal cancer (CRC) survivors. It can interact with physical symptoms, impacting cancer progression, survival, and quality of life. This scoping review aims to explore the factors associated with anxiety in patients with CRC and the instruments used to measure anxiety. METHODS: Using Arksey and O'Malley's (2005) framework for the scoping review, studies investigating anxiety in CRC patients published in CINAHL, PubMed, PsycINFO, and Scopus between 2013 and 2024 were included. RESULTS: We analyzed fifty-one studies for this review. The review identified several risk factors and consequences of anxiety in CRC patients. The risk factors were classified into six domains using Niedzwiedz et al.'s (2019) framework: individual characteristics, social/ contextual factors, prior psychological factors, psychological responses to diagnosis and treatment, characteristics of cancer, and treatment. The consequences of anxiety were classified into three categories: global health status/quality of life, functions, and symptoms/problems. The most frequently used tool was the Hospital Anxiety and Depression Scale, with International Classification of Diseases codes being the second most used. CONCLUSIONS: This scoping review highlighted the intricate interaction between biological and psychosocial aspects in the lives of CRC survivors. It also identified unique factors associated with anxiety among these individuals. However, the review found some inconsistencies in the results related to anxiety-related factors, potentially due to differences in study populations, designs, measurement tools, and analysis methods. IMPLICATIONS FOR CANCER SURVIVORS: This review underscores the potential for interventions targeting modifiable factors to prevent or reduce anxiety and enhance the quality of life for CRC survivors.

Male breast cancer: a 32-year retrospective analysis in radiation therapy referral center in northern Iran.

Background: Breast cancer commonly occurs in women, and male breast cancer makes up less than 1% of all cases of breast cancer. The limited prevalence of male breast cancer has led to decreased attention being paid to this condition, resulting in its diagnosis occurring at later ages and at more severe disease stages. Objectives: This study evaluates the demographic and clinicopathological characteristics of male patients diagnosed with breast cancer who visited the northern region of Iran from 1992 to 2023. Methods: This descriptive study reviewed data from 58 cases of male breast cancer between 1992 and 2023. The study aimed to examine and describe the information connected to these patients. The data were analyzed with SPSS.22 set at P value less than 0.05. Results: The mean age of the patients examined was 62.10±13.40 years, while their mean BMI was 27.08±4.95. The study found no statistically significant correlation between BMI with stage and kinds of recurrence, including metastasis and local recurrence (P>0.05). The right and left breast involvement rates were equal (48.28%) in 28 cases, and 2 cases (3.40%) had bilateral involvement. The bone was the predominant site of metastasis, accounting for 69.23% of cases. The analysis revealed no significant correlation between stage and metastasis (P=1.000) or local recurrence (P=0.543). Most metastasis and all the local recurrence were observed in stages 3 and 4. Conclusion: Male breast cancer mainly occurs in older age and is diagnosed in the advanced stages of the disease. Therefore, it is recommended to inform men and develop suitable screening programs, especially in high-risk families.

A Comprehensive Study of Risk Factors, Etiology, and Infarction Patterns in Cerebrovascular Accidents at a Tertiary Care Hospital in India.

Background Stroke is a debilitating cerebrovascular condition characterized by sudden neurological deficits. The incidence of stroke is rising in India, posing significant public health concerns. This study aims to examine the risk factors and etiology of stroke using the Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification and analyze infarct areas in cerebrovascular accidents (CVA) at a tertiary care hospital. Methodology This cross-sectional, hospital-based observational study was conducted at Dr. D. Y. Patil Medical College, Hospital and Research Centre, Dr. D. Y. Patil Vidyapeeth (Deemed to Be University), Pune, India, from January 2023 to January 2024. The study included 100 adult patients diagnosed with CVA based on clinical and radiological criteria. Patients aged 18 years and older were eligible, while those with a history of head trauma or those below 18 years were excluded. The investigation protocol included routine biochemical assessments and radiological investigations, such as computed tomography (CT), magnetic resonance imaging (MRI) with angiography or venography, and Doppler ultrasound of bilateral carotid arteries. Results The study population consisted of 100 patients, with 84 males (84%) and 16 females (16%). Age distribution showed 44% were over 60 years old, 23% aged 51-60 years, 15% aged 31-40 years, 14% aged 41-50 years, and 4% aged 21-30 years. Hypertension was the most prevalent risk factor, affecting 75% of patients, with a higher occurrence in males (62%), compared to females (13%). Smoking was observed in 51% of patients, and alcohol consumption was seen in 50%. Other significant risk factors included dyslipidemia (39%), diabetes mellitus (33%), chronic kidney disease (11%), ischemic heart disease (10%), atrial fibrillation (4%), valvular heart disease (4%), and pregnancy or postpartum conditions (2%). Ischemic stroke was predominant, occurring in 80% of patients, while hemorrhagic stroke occurred in 20%. High occurrences of ischemic strokes were noted in the frontal lobe (41%), parietal lobe (37%), occipital lobe (27%), and temporal lobe (26%), with the internal capsule region also showing significant numbers (27%). According to the TOAST classification, the most prevalent cause of stroke in this study was undetermined etiology with two or more causes, accounting for 32% of cases, followed by large artery atherosclerosis, which accounted for 30%. Cardioembolic stroke was identified in 11% of the patients, with 4% due to atrial fibrillation, 3% due to acute myocardial infarction, 3% due to rheumatic valvular heart disease, and 1% due to infective endocarditis. Conclusion This study highlights the significant prevalence of hypertension, smoking, alcohol consumption, and hyperhomocysteinemia as major risk factors for stroke. Ischemic strokes were predominant, with high occurrences in the cerebral lobes and gangliocapsular region. These findings emphasize the need for targeted prevention strategies, including managing hypertension and lifestyle modifications such as smoking cessation and reducing alcohol consumption, to mitigate the risk of stroke. Effective management of blood pressure, lipid levels, and blood glucose is crucial for stroke prevention. Recognizing gender-specific differences and addressing comorbidities through an integrated approach can enhance patient outcomes and reduce the burden of stroke.

Association between dietary factors and breast cancer risk: a matched case-control study in Vietnam.

BACKGROUND: The role of diet in breast cancer prevention is controversial and limited in low-middle-income countries (LMICs). This study aimed to investigate the association between different dietary factors and breast cancer risk in Vietnamese women. METHODS: Three hundred seventy newly histologically confirmed breast cancer cases and 370 controls matched by 5-year age from September 2019 to March 2020 in Ho Chi Minh City were recorded dietary intake using a validated food frequency questionnaire. Odds ratios (OR) and 95% confidence intervals (95% CI) were evaluated using conditional logistic regression and adjusted with potential confounders. RESULTS: Compared to the lowest quartile of intake, we found that the highest intake of vegetables, fruit, soybean products, coffee, and egg significantly decreased breast cancer risk, including dark green vegetables (OR 0.46, 95% CI 0.27-0.78, ptrend=0.022), legumes (OR 0.19, 95% CI 0.08-0.44, ptrend <0.001), starchy vegetables (OR 0.37, 95% CI 0.21-0.66, ptrend=0.003), other vegetables (OR 0.46, 95% CI 0.28-0.77, ptrend=0.106), fruits (OR 0.44, 95% CI 0.26-0.74, ptrend <0.001), soybean product (OR 0.45, 95% CI 0.24-0.86, ptrend=0.311), coffee (OR 0.47, 95% CI 0.23-0.95, ptrend 0.004), and egg (OR 0.4, 95% CI 0.23-0.71, ptrend=0.002). CONCLUSION: Greater consumption of vegetables, fruit, soybean products, coffee, and eggs is associated with a lower risk of breast cancer. This study provides evidence of breast cancer prevention by increasing the intake of these dietary groups, especially in LMICs.

Clinical characteristics and predictive factors of recurrent idiopathic transverse myelitis.

Background: Idiopathic transverse myelitis (iTM) is defined as an inflammatory myelopathy of undetermined etiology, even after a comprehensive workup to identify other possible causes. Generally, the characteristics of recurrent iTM are not clearly defined. This study aimed to identify the clinical characteristics and predictive factors of recurrence in patients with iTM. Methods: We retrospectively recruited patients with transverse myelitis (TM) who visited Chungnam National University Hospital between January 2011 and December 2021. We included patients who were followed up for at least 2 years and excluded those diagnosed with multiple sclerosis or neuromyelitis optica spectrum disorder (NMOSD) during the initial episode or follow-up period. Patients with iTM were categorized into two groups: monophasic idiopathic TM (mTM) and recurrent idiopathic TM (rTM). We compared the clinical characteristics and spinal magnetic resonance imaging findings between the two groups. Results: In total, 167 patients were reviewed, of whom 112 were excluded. Finally, we included 55 patients with iTM. In 55 patients, 11 (20.0%) and 44 (80%) were classified into the rTM and mTM groups, respectively. Male predominance was observed in the iTM, rTM, and mTM groups. The percentage of patients with low vitamin D levels was significantly higher in the rTM group (100.0%) compared with the mTM group (70%) (p = 0.049). In addition, longitudinally extensive transverse myelitis (LETM) was observed more frequently in the rTM group, in 8 of 11 (72.7%) patients, compared with 15 of 44 (34.1%) patients in the mTM group, with the difference being statistically significant (p = 0.020). In multivariate regression analysis, female sex, younger age at onset, low serum vitamin D level (<30 ng/mL), and LETM were risk factors for recurrence. LETM was a significant predictor of relapse in iTM (p = 0.043, odds ratio = 13.408). Conclusion: In this study, the clinical features of mTM and rTM are nearly indistinguishable. In conclusion, >20% of the patients with iTM experience recurrence, and LETM is the most significant risk factor for recurrence. In cases of recurrence, there is a favorable response to immunotherapy, and the prognosis is generally good. Although LETM may be the initial symptom of NMOSD, it may be manifestation of iTM, and in cases of idiopathic LETM, it is important to be mindful of the elevated risk of recurrence. Based on these results, idiopathic rTM has good clinical prognosis and response to immunosuppressive treatment.

Prevalence, Risk Factors and Pain Subtypes of Post-COVID Pain in Nonhospitalized Older Adults: A Cross-Sectional Study.

BACKGROUND: Post-COVID pain (PCP) is a condition that ensues from an infection of coronavirus disease 2019 (COVID-19). Some researchers have explored the prevalence of PCP and its characteristics in the individuals who experience it. However, most individuals involved in the previous studies were middle-aged, and those studies focused mainly on hospital patients and musculoskeletal PCP. Existing data on PCP and its subtypes among older adults and outpatients are scanty. OBJECTIVE: Our study aims to identify PCP's prevalence and associated risk factors and to compare the quality of life (QoL), sleep quality, and anxiety and depression levels in nonhospitalized elderly COVID-19 survivors with different PCP subtypes. STUDY DESIGN: A cross-sectional study. SETTING: The study was conducted from April 2023 to June 2023 after the first outbreak of the Omicron variant of SARS-CoV-2 in the Taikang Yanyuan Continuing Care Retirement Community (CCRC) in China. METHODS: Eligible participants were surveyed using the Numeric Rating Scale (NRS), Douleur Neuropathique-4 questionnaire (DN4), EuroQol 5D-5L questionnaire (EQ-5D-5L), Pittsburgh Sleep Quality Index (PSQI), Generalized Anxiety Disorder 7 (GAD-7) scale, and Patient Health Questionnaire-9 (PHQ-9) scale. COVID-19 symptoms and laboratory parameters were obtained through an electronic healthcare system. Descriptive analysis was performed based on the presence of PCP and PCP subtypes. Multivariable logistic regression analysis and multiple linear regression were used for risk-factor analysis and adjustment of confounding factors. RESULTS: A total of 668 individuals (female: 59.3%, median age: 84 years) who had been infected with COVID-19 for a median duration of 145 (126-168) days were enrolled in our study. PCP was observed in 9.4% (63/668) of elderly COVID-19 survivors. Number of COVID-19 symptoms (aOR 1.31, 95%CI 1.05-1.64, P = 0.018) and previous chronic pain (aOR 4.24, 95%CI 1.59-11.27, P = 0.004) were risk factors associated with PCP. Individuals with neuropathic PCP exhibited higher NRS scores (5 [5-6] vs. 3 [3-4], P < 0.001) and more use of analgesic drugs (70.0%, 7/10 vs. 20.8%, 11/53, P = 0.005) for pain management. Neuropathic PCP was associated with lower scores on the EQ-5D index (B = -0.210, 95% CI -0.369 to -0.051, P = 0.011) and EQ-VAS (B = -10.808, 95% CI -21.149 to -0.468, P = 0.041) and higher PHQ-9 scores (B = 3.154, 95% CI 0.674-5.634, P = 0.014). LIMITATIONS: It is difficult to establish a strong causality between PCP and SARS-CoV-2 infection due to the study's cross-sectional nature. Selection bias could not be eliminated, since our study relied on volunteer participation. Due to neuropathic PCP's lower prevalence than nonneuropathic PCP, larger sample sizes and multicenter studies are crucial for a comprehensive understanding of the neuropathic PCP condition. CONCLUSION: Our study found a PCP prevalence of 9.4% in nonhospitalized older adults who had survived COVID-19. Number of COVID-19 symptoms and history of previous chronic pain seemed to be potential risk factors for PCP. Neuropathic PCP was associated with lower QoL and a more severe depression level.
