Objective To analyze the occurrence and risk factors of needlestick and sharps injuries(NSIs)among oral health care workers(HCWs).Methods NSIs reported by West China Hospital of Stomatology from 2020 to 2023 were collected,and factors relevant to NSIs were analyzed.Results A total of 391 cases of NSIs were repor-ted.Only one case of injury was caused by a sterile device,while the remaining 390 cases were caused by contamina-ted devices.There were 85,107,113,and 86 cases in 2020,2021,2022,and 2023,respectively.Most NSIs oc-curred among interns(n=235,60.1％).294 cases(75.2％)of NSIs occurred among HCWs who had less than 3 years of clinical experience.The distribution of NSIs among 235 interns in different months showed that NSIs ac-counted for a relatively high proportion from April to June and July to September,and the difference was statistica-lly significant(P＜0.05).The ventral side of the left thumb was the most common site of NSIs(n=53,13.6％),followed by the ventral side of the right index finger(n=45,11.5％)and the ventral side of the left index finger(n=44,11.3％).The most common devices involved in NSIs were various types of syringe needles(n=84,21.5％),followed by various types of dental burs(n=76,19.4％)and suture needles(n=49,12.5％).Injuries mainly oc-curred during the treatment process(n=212,54.2％)and in the department of endodontics(n=86,22.0％).This study didn't find any occupational bloodborne infection case caused by NSIs.Conclusion NSIs mainly occur among inexperienced oral interns,and devices causing NSIs are related to the treatment process.

Objective To mine and analyze signals of acute kidney injury(AKI)related to drugs,comprehensively summarize the potential risk drugs,and provide a reference for clinically safe medication.Methods The AKI reports from January 2004 to September 2023 in the US FDA Adverse Event Reporting System(FAERS)were retrieved.Disproportionality methods were used to explore the relationship between drugs and AKI,and demographic information,time to onset,and patient outcomes were analyzed.Results Out of 1 253 drugs,159 were identified as AKI signal drugs.Among these,there were 49 antimicrobial agents(30.82%),including 35 antibiotics and 14 antiviral agents;33 antineoplastic agents(20.75%);and 25 hypotensive agents(15.72%).Drug-related AKI occurred mostly in the elderly,and the male-to-female ratio was 124∶100.The median time to onset for AKI related to antibiotics was≤8 d,with the third quartile≤21 d.Rivaroxaban and aspirin had higher proportions of death reports,with 33.03%and 31.44%respectively.Conclusions A multitude of drugs pose a risk for acute kidney injury,necessitating caution in their clinical application and the implementation of monitoring of renal function.The elderly are a high-risk group for drug-related AKI,and there are more males than females.For antibiotics,the first 21 days are the key monitoring period.For drugs that require long-term use,regular monitoring is necessary.

Objective:To compare the mydriatic effects of a combination of 1% tropicamide and 2.5% phenylephrine with a 0.5% tropicamide and 0.5% phenylephrine combination in patients with type 2 diabetes.Methods:A randomized, double-blind, controlled trial was conducted.Ninety Chinese patients (90 eyes) with dark irises and type 2 diabetes who needed mydriasis examination at the Fundus Disease Clinic of Tianjin Medical University Eye Hospital from June to September 2024 were included.The subjects were divided into control group (30 patients 30 eyes), high concentration group (30 patients 30 eyes) and half-dilution group (30 patients 30 eyes) using the random number table method, which received 2 drops of a mixture of 0.5% tropicamide and 0.5% phenylephrine, 2 drops of a mixture of 1% tropicamide and 2.5% phenylephrine, 1 drop of a mixture of 1% tropicamide and 2.5% phenylephrine+ 1 drop of saline respectively.The pupil diameter of the patients was measured with a pupillometer 40 minutes before and after instillation.The study adhered to the Declaration of Helsinki and the study protocol was approved by the Ethics Committee of Tianjin Medical University Eye Hospital (No.2024KY-16).Written informed consent was obtained from all participants.Results:The proportions of patients whose pupil diameters reached 7 mm 40 minutes after the initial administration in the control group, high-concentration group, and half-dilution group were 56.7%(17/30), 86.7%(26/30) and 66.7%(20/30), respectively, with a statistically significant overall difference ( χ2=6.667, P=0.036).The proportion of patients in the high-concentration group whose pupil diameter reached 7 mm 40 minutes after the initial administration was higher than that in the control group, and the difference was statistically significant ( P<0.05).The pupil diameters 40 minutes after the initial administration in the control group, the high-concentration group and the half-dilution group were (7.01±0.86), (7.64±0.61) and (7.49±1.15)mm, respectively, with a statistically significant overall difference ( F=4.019, P=0.021), and the pupil diameter of the high-concentration group was significantly higher than that of the control group ( P=0.024).Changes in pupil diameter 40 minutes after the initial administration in the control group, high-concentration group and half-dilution group were (3.23±0.81), (3.82±0.60) and (3.62±0.75)mm, respectively, with a statistically significant overall difference ( F=5.121, P=0.008), and the change in pupil diameter in the high-concentration group was higher than that in the control group ( P=0.007). Conclusions:The combination of 1% tropicamide and 2.5% phenylephrine has better pupil dilation than the combination of 0.5% tropicamide and 0.5% phenylephrine.It is recommended that pupil dilation be performed with a high-concentration mydriatic drug prior to outpatient fundus examination for diabetic patients.

Objective:To investigate the prevalence and influencing factors of post-traumatic stress disorder (PTSD) in thyroid cancer patients.Methods:This cross-sectional study used convenience sampling to recruit thyroid cancer patients from the Thyroid Surgery Department of Harbin Medical University Cancer Hospital between July and September 2023. Data were collected using a general demographic questionnaire, the Post-Traumatic Stress Disorder Checklist-Civilian Version (PCL-C), the Perceived Stress Scale (PSS-10), and the Negative Cognitive Processing Bias Questionnaire (NCPBQ) .Results:A total of 210 questionnaires were distributed, and 204 valid responses were returned, yielding a response rate of 97.14% (204/210). Among the respondents, 44 patients (21.57%) tested positive for PTSD, with a PCL-C score of 23 (19, 32). Factors influencing PTSD included age, education level, marital status, monthly income, lateral neck lymph node metastasis, comorbid chronic diseases, perceived stress, and negative cognitive processing bias ( P<0.05) .

Objective:To investigate the clinical efficacy of repetitive transcranial magnetic stimulation (rTMS) versus functional electrical stimulation (FES) in the treatment of post-stroke complex regional pain syndrome. Methods:The randomized controlled study included 60 patients with post-stroke complex regional pain syndrome who received treatment at the Wenzhou TCM Hospital of Zhejiang Chinese Medical University from July 2021 to February 2023. These patients were divided into an rTMS group ( n = 30) and an FES group ( n = 30) using a random number table method. Patients in the rTMS group were treated with rTMS, while those in the FES group were treated with FES. All treatments were performed once daily for 8 consecutive weeks. The clinical efficacy, total active movement score of the fingers, Fugl-Meyer assessment scale score, Activity of Daily Living score, modified Barthel Index score, shoulder joint range of motion, and safety were compared between the two groups. Results:The total response rate in the FES group was 86.7% (26/30), which was significantly higher than 83.3% (25/30) in the rTMS group ( Z = 0.09, P = 0.93). After treatment, there were no significant differences between the two groups in terms of total active movement score of the fingers and Fugl-Meyer assessment scale score ( P = 0.244, 0.262). No significant differences were found between the two groups in MBI score and ADL score (both P > 0.05). There was also no significant difference in shoulder joint range of motion between the two groups ( P > 0.05). Conclusion:Both rTMS and FES are highly effective for post-stroke complex regional pain syndrome. They can improve upper limb function, enhance daily living abilities, and remodel neurological functions of the brain.
