Association of cardiometabolic multimorbidity with all-cause and cardiovascular disease mortality among Chinese hypertensive patients

BACKGROUND Hypertension usually clusters with multiple comorbidities.However,the association between cardiometabolic multimorbidity(CMM)and mortality in hypertensive patients is unclear.This study aimed to investigate the association between CMM and all-cause and cardiovascular disease(CVD)mortality in Chinese patients with hypertension.METHODS The data used in this study were from the China National Survey for Determinants of Detection and Treatment Status of Hypertensive Patients with Multiple Risk Factors(CONSIDER),which comprised 5006 participants aged 19–91 years.CMM was defined as the presence of one or more of the following morbidities:diabetes mellitus,dyslipidemia,chronic kidney disease,coronary heart disease,and stroke.Cox proportional hazard models were used to calculate the hazard ratios(HR)with 95%CI to determine the association between the number of CMMs and both all-cause and CVD mortality.RESULTS Among 5006 participants[mean age:58.6±10.4 years,50%women(2509 participants)],76.4%of participants had at least one comorbidity.The mortality rate was 4.57,4.76,8.48,and 16.04 deaths per 1000 person-years in hypertensive patients without any comorbidity and with one,two,and three or more morbidities,respectively.In the fully adjusted model,hypertensive participants with two cardiometabolic diseases(HR=1.52,95%CI:1.09–2.13)and those with three or more cardiometabolic diseases(HR=2.44,95%CI:1.71–3.48)had a significantly elevated risk of all-cause mortality.The findings were similar for CVD mortality but with a greater increase in risk magnitude.CONCLUSIONS In this study,three-fourths of hypertensive patients had CMM.Clustering with two or more comorbidities was associated with a significant increase in the risk of all-cause and cardiovascular mortality among hypertensive patients,suggesting more intensive treatment and control in this high-risk patient group.

Multimorbidity and mortality among older patients with coronary heart disease in Shenzhen,China

BACKGROUND The current understanding of the magnitude and consequences of multimorbidity in Chinese older adults with coronary heart disease(CHD)is insufficient.We aimed to assess the association and population-attributable fractions(PAFs)between multimorbidity and mortality among hospitalized older patients who were diagnosed with CHD in Shenzhen,China.METHODS We conducted a retrospective cohort study of older Chinese patients(aged≥65 years)who were diagnosed with CHD.Cox proportional hazards models were used to estimate the associations between multimorbidity and all-cause and cardiovascular disease(CVD)mortality.We also calculated the PAFs.RESULTS The study comprised 76,455 older hospitalized patients who were diagnosed with CHD between January 1,2016,and August 31,2022.Among them,70,217(91.9%)had multimorbidity,defined as the presence of at least one of the predefined 14 chronic conditions.Those with cancer,hemorrhagic stroke and chronic liver disease had the worst overall death risk,with adjusted HRs(95%CIs)of 4.05(3.77,4.38),2.22(1.94,2.53),and 1.85(1.63,2.11),respectively.For CVD mortality,the highest risk was observed for hemorrhagic stroke,ischemic stroke,and chronic kidney disease;the corresponding adjusted HRs(95%CIs)were 3.24(2.77,3.79),1.91(1.79,2.04),and 1.81(1.64,1.99),respectively.All-cause mortality was mostly attributable to cancer,heart failure and ischemic stroke,with PAFs of 11.8,10.2,and 9.1,respectively.As for CVD mortality,the leading PAFs were heart failure,ischemic stroke and diabetes;the corresponding PAFs were 18.0,15.7,and 6.1,respectively.CONCLUSIONS Multimorbidity was common and had a significant impact on mortality among older patients with CHD in Shenzhen,China.Cancer,heart failure,ischemic stroke and diabetes are the primary contributors to PAFs.Therefore,prioritizing improved treatment and management of these comorbidities is essential for the survival prognosis of CHD patients from a holistic public health perspective.

Virtual reality for preoperative patient education: Impact on satisfaction, usability, and burnout from the perspective of new nurses

BACKGROUND Traditional paper-based preoperative patient education is a struggle for new nurses and requires extensive training.In this situation,virtual reality technology can help the new nurses.Despite its potential benefits,there are studies on patient satisfaction but there is limited information on the usability of virtual reality(VR)technology for new nurses in giving preoperative education to patients.AIM To investigate the impact on satisfaction,usability,and burnout of a system using VR technology in preoperative patient education.METHODS The study involved 20 nurses from the plastic surgery ward and 80 patients admitted between April and May 2019.Each nurse taught four patients:Two using traditional verbal education and two using virtual reality.The System Usability Scale,After-Scenario Questionnaire,and Maslach Burnout Inventory(MBI)were employed to evaluate the impact of these education methods.RESULTS The VR education groups showed a statistically higher satisfaction than the traditional verbal education groups.Among the three subscales of the MBI,emotional exhaustion and personal accomplishment improved statistically significantly.VR was also better in terms of usability.CONCLUSION This study suggests VR enhances usability and reduces burnout in nurses,but further research is needed to assess its impact on depersonalization and objective measures like stress and heart rate.

Predictive modeling for postoperative delirium in elderly patients with abdominal malignancies using synthetic minority oversampling technique

BACKGROUND Postoperative delirium,particularly prevalent in elderly patients after abdominal cancer surgery,presents significant challenges in clinical management.AIM To develop a synthetic minority oversampling technique(SMOTE)-based model for predicting postoperative delirium in elderly abdominal cancer patients.METHODS In this retrospective cohort study,we analyzed data from 611 elderly patients who underwent abdominal malignant tumor surgery at our hospital between September 2020 and October 2022.The incidence of postoperative delirium was recorded for 7 d post-surgery.Patients were divided into delirium and non-delirium groups based on the occurrence of postoperative delirium or not.A multivariate logistic regression model was used to identify risk factors and develop a predictive model for postoperative delirium.The SMOTE technique was applied to enhance the model by oversampling the delirium cases.The model’s predictive accuracy was then validated.RESULTS In our study involving 611 elderly patients with abdominal malignant tumors,multivariate logistic regression analysis identified significant risk factors for postoperative delirium.These included the Charlson comorbidity index,American Society of Anesthesiologists classification,history of cerebrovascular disease,surgical duration,perioperative blood transfusion,and postoperative pain score.The incidence rate of postoperative delirium in our study was 22.91%.The original predictive model(P1)exhibited an area under the receiver operating characteristic curve of 0.862.In comparison,the SMOTE-based logistic early warning model(P2),which utilized the SMOTE oversampling algorithm,showed a slightly lower but comparable area under the curve of 0.856,suggesting no significant difference in performance between the two predictive approaches.CONCLUSION This study confirms that the SMOTE-enhanced predictive model for postoperative delirium in elderly abdominal tumor patients shows performance equivalent to that of traditional methods,effectively addressing data imbalance.

Patient satisfaction and follow-up adherence to glaucoma case management clinic in China

AIM:To assess glaucoma patient satisfaction and follow-up adherence in case management and identify associated predictors to improve healthcare quality and patient outcomes.METHODS:In this cross-sectional study,a total of 119 patients completed a Patient Satisfaction Questionnaire-18 and a sociodemographic questionnaire.Clinical data was obtained from the case management system.Follow-up adherence was defined as completing each follow-up within±30d of the scheduled time set by ophthalmologists during the study period.RESULTS:Average satisfaction scored 78.65±7,with an average of 4.39±0.58 across the seven dimensions.Age negatively correlated with satisfaction(P=0.008),whilst patients with follow-up duration of 2 or more years reported higher satisfaction(P=0.045).Multivariate logistics regression analysis revealed that longer follow-up durations were associated with lower follow-up adherence(OR=0.97,95%CI,0.95-1.00,P=0.044).Additionally,patients with suspected glaucoma(OR=2.72,95%CI,1.03-7.20,P=0.044)and those with an annual income over 100000 Chinese yuan demonstrated higher adherence(OR=5.57,95%CI,1.00-30.89,P=0.049).CONCLUSION:The case management model proves effective for glaucoma patients,with positive adherence rates.The implementation of this model can be optimized in the future based on the identified factors and extended to glaucoma patients in more hospitals.

Depression and anxiety among cancer patients visiting a tertiary care cancer hospital

BACKGROUND Cancer patients frequently experience psychological problems related to reactions to cancer diagnosis,cancer type and stage,treatment effects,recurrence,fear of end-of-life,survivorship,and financial burden.Depression and anxiety are both psychological and physiological disturbances among cancer patients.AIM To assess the prevalence of depression and anxiety among cancer patients attending a tertiary care cancer hospital.METHODS A cross-sectional study was conducted at Bhaktapur Cancer Hospital in Kathmandu Valley among 220 cancer patients aged from 18 years to 70 years.Ethical approval was taken from the Institutional Review Committee of CiST College.Convenient sampling was used to interview patients with the standardized Patient-Health Questionnaire(PHQ-9)for Depression and Hospital Anxiety and Depression sub-scale(HADS-A)for anxiety.Epi-Data was used for data entry and transferred to SPSS Version 25 for analysis.RESULTS The study revealed that of 220 patients,most of the respondents belonged to the age group 51-60 years.More than half 131(59.6%)of the respondents were female,most of them had depression,and one-third had anxiety.Among the respondents,124(56.4%)had mild depression,70(31.8%)had moderate depression,and 3(1.3%)had severe depression;79(35.9%)had mild anxiety,64(29.1%)had moderate anxiety,and 4(1.8%)had severe anxiety.CONCLUSION Most respondents were depressed and one-third had anxiety.More than half and nearly one-third had mild and moderate depression,respectively,and nearly one-third had mild and moderate anxiety,which is higher than other studies.

Effect of remimazolam vs. propofol on hemodynamics during general anesthesia induction in elderly patients: Single-center, randomized controlled trial

The current study aimed to compare the effects between remimazolam and propofol on hemodynamic stability during the induction of general anesthesia in elderly patients.We used propofol at a rate of 60 mg/(kg·h)in the propofol group(group P)or remimazolam at a rate of 6 mg/(kg·h)in the remimazolam group(group R)for the induction.A processed electroencephalogram was used to determine whether the induction was successful and when to stop the infusion of the study drug.We measured when patients entered the operating room(T_(0)),when the induction was successful(T_(1)),and when before(T_(2))and 5 min after successful endotracheal intubation(T_(3)).We found that mean arterial pressure(MAP)was lower at T_(1–3),compared with T_(0) in both groups,but higher at T_(2) in the group R,whileΔMAP_(T0–T2) andΔMAP_(max) were smaller in the group R(ΔMAP_(T0–T2):the difference between MAP at time point T_(0) and T_(2),ΔMAP_(max):the difference between MAP at time point T_(0) and the lowest value from T_(0) to T_(3)).Cardiac index and stroke volume index did not differ between groups,whereas systemic vascular resistance index was higher at T_(1–3) in the group R.These findings show that remimazolam,compared with propofol,better maintains hemodynamic stability during the induction,which may be attributed to its ability to better maintain systemic vascular resistance levels.

Initial clinical evaluation of chest digital tomosynthesis in adult patients with COVID-19 pneumonia

To the Editor:The coronavirus disease 2019(COVID-19)pandemic has caused a significant global health crisis,led to staggering mortality rates,and imposed a substantial economic burden.[1]Pneumonia is the leading cause of mortality in patients with COVID-19.During outbreak peaks,the surge in patients severely strained healthcare systems,highlighting the need for rapid and cost-effective screening methods.Although chest X-ray(CXR)is affordable and convenient,its low sensitivity limits its effectiveness for detecting lung abnormalities.Computed tomography(CT)is considered the gold standard for diagnosing pneumonia,including COVID-19 pneumonia,but it exposes patients to high doses of radiation(3-7 mSv)far exceeding the annual threshold of 1 mSv recommended by the World Health Organization.Even low-dose CT delivers an average effective dose of 1.6 mSv,adding to the patient’s radiation burden.

Clinical and cost analysis of an ultra-rapid metagenomic sequencing test for pathogen detection in adult patients with sepsis

To the Editor:Sepsis is a clinical syndrome characterized by life-threatening organ dysfunction caused by a dysregulated host response to infection.Early intervention with antibiotics,intravenous fluids,and other supportive measures can significantly improve the chances of recovery.For every hour of delay in diagnosing and treating patients with septic shock,there is a 7.6%increase in the mortality rate.[1]Despite advances in diagnostic technology,clinicians are still unable to detect the origin of sepsis in approximately one-quarter(28%)of patients with septic shock by the end of their intensive care unit(ICU)stay.[2]Therefore,a more rapid test to detect a broad spectrum of pathogens is essential for the diagnosis and treatment of sepsis.

Efficacy and safety of abrocitinib in Chinese patients with moderate-to-severe atopic dermatitis:A post hoc analysis of the JADE REGIMEN phase 3 trial

To the Editor:Atopic dermatitis(AD)is a chronic inflammatory skin disorder with a relapsing-remitting disease course that warrants flexible dosing.[1,2]In China,abrocitinib,an oral,once-daily,Janus kinase 1-selective inhibitor,is approved at a 100 mg starting dose for adults with refractory moderate-to-severe AD who did not inadequately respond to other systemic therapies(i.e.,corticosteroids or biologics),or for whom these treatments are not advisable.If the response achieved with abrocitinib 100 mg is inadequate,200 mg dosing can be considered,which could be administered as a short-term treatment(≤12 weeks).[3]The phase 3 JADE REGIMEN trial(Clinicaltrials.gov,NCT03627767)evaluated maintenance of response with continuous-dose abrocitinib(200 mg),reduced-dose abrocitinib(100 mg),or drug withdrawal(placebo)in patients with moderate-to-severe AD who responded to abrocitinib induction therapy.[4]Here,we aimed to characterize the efficacy and safety of abrocitinib in the Chinese mainland subgroup within JADE REGIMEN.

Influence of biological treatments on intestinal microbiota of psoriasis patients

To the Editor:Psoriasis is a common,chronic inflammatory skin disease occurring worldwide and presenting at any age.[1]Biologics are the most important therapeutic advances in psoriasis treatment.[2]With the development of 16S rRNA sequencing technology,the association between psoriasis and intestinal flora has been gradually revealed.Some bacteria secrete short-chain fatty acids(SCFAs)with anti-inflammatory properties,serving as active microbial metabolites that regulate the function of immune cells in the intestine and other tissues.[3]However,the impact of biological treatment on gut microbiota and related functional changes in psoriasis patients remains unclear.Our study aimed to explore the effects of biological treatments on the intestinal microbiota of psoriasis patients.

A young patient with Trousseau syndrome presenting with multiple arterial emboli

Trousseau syndrome is characterized by thromboembolism induced by malignancy[1]and typically affects middle-aged to elderly patients.[2-4]When faced with a young patient suffering from cerebral infarction and diffuse arterial emboli,there is some controversy regarding whether to consider it a concurrent malignancy triggering Trousseau syndrome or to adhere to TOAST(Trial of Org 10172 in Acute Stroke Treatment)for common causes.[5,6]In this case study,we aimed to report a young patient with Trousseau syndrome presenting with multiple arterial emboli.

Effects of dexmedetomidine on emergence delirium and electroencephalogram during the recovery period in older patients undergoing lower limb orthopedic surgery:A randomized,double-blind,placebo-controlled clinical trial

To the Editor:Delirium is a common postoperative complication associated with multiple adverse clinical outcomes in older patients.[1]According to the time of onset,delirium in the postoperative stage can be divided into emergence delirium(ED)and postoperative delirium(POD).ED occurs during or immediately after awakening from general anesthesia,whereas POD is usually found during postoperative days 1-7.Assessing patients for ED provides the first clue of a possible postoperative neurocognitive disorder.[2]Dexmedetomidine(DEX)is a highly selectiveα-2 receptor agonist that is increasingly used in the perioperative period to induce sedation,analgesia.

Hemoperfusion and continuous veno-venous hemodiafiltration for eliminating chlorfenapyr in poisoning patients

Chlorfenapyr is a liposoluble insecticide belonging to the pyrrole family.Chlorfenapyr is activated when the N-ethoxymethyl side chain breaks,forming a toxic metabolite,which uncouples oxidative phosphorylation in the mitochondria,inhibits the production of adenosine triphosphate (ATP),and leads to the death of cells and targe organisms.[1] Symptoms of chlorfenapyr poisoning in patients are mild and atypical in the early stage,especially in patients receiving low dose exposure;however,such cases are rare and may be ignored by physicians,often leading to delayed treatment.[2,3].

Focusing on the tetra-partite synapse in Parkinson’s disease research using human patient-derived neurons

Parkinson’s disease(PD)was first described as a neurological disease by Dr.James Parkinson in 1817 as a“shaking palsy”.Since that time,much more is known about the pathophysiology of PD yet the disease is still uncurable.The hallmark of the disease is often considered Lewy body neural inclusions in the substantia nigra pars compacta and other brain areas,although not all patients have these inclusions.The patients exhibit massive neuronal cell loss in the substantia nigra pars compacta,which is associated with the motor symptoms of tremor,bradykinesia,rigidity,and postural instability.PD is the second most common neurodegenerative disease after Alzheimer’s disease with a prevalence of around 1%of individuals over the age of 60.

Impact of peri-operative venous thromboembolism on survival in patients with endometrial clear cell carcinoma:A 10-year single-institution retrospective study

To the Editor:Endometrial cancer(EC)is the sixth most common cancer diagnosed in women,and its prevalence is reportedly increasing worldwide.Endometrial clear cell carcinoma(ECCC)accounts for 2-5%of all EC,and is a rare but ominous subtype of high-risk EC that has a poorer prognosis and exhibits greater chemoresistance.Owing to the rarity of ECCC,few clinical trials have included patients with this disease exclusively,and limited data are available regarding its pathogenesis and clinical progression compared with other more common subtypes of EC.
