This case report explores the therapeutic potential of theta burst stimulation (TBS) for cognitive enhancement in individuals with brain injuries. The study presents a 38-year-old male suffering from an organic mental disorder attributed to a traumatic brain injury (TBI), who demonstrated notable cognitive improvements following an intensive TBS protocol targeting the left dorsal lateral prefrontal cortex. The treatment led to significant enhancements in impulse control, irritability, and verbal comprehension without adverse effects. Neuropsychological assessments and brain imaging post-intervention revealed improvements in short-term memory, abstract reasoning, list-generating fluency, and increased cerebral blood flow in the prefrontal cortex. These findings suggest that TBS, by promoting neural plasticity and reconfiguring neural networks, offers a promising avenue for cognitive rehabilitation in TBI patients. Further research is warranted to optimize TBS protocols and understand the mechanisms underlying its cognitive benefits.

Objective:To explore the maintenance of sinus rhythm and the changes in functional tricuspid regurgitation(FTR) in patients with atrial fibrillation(AF) combined with FTR following the Mei Mini Maze Procedure, and to analyze the correlation between these two factors.Methods:We retrospectively included 180 patients with AF and FTR who underwent left-sided thoracoscopic AF ablation(the Mei Mini Maze Procedure) at Xinhua Hospital in Shanghai from January 2019 to December 2021. After propensity score matching to eliminate confounding factors, the patients were divided into two groups based on the severity of FTR before surgery: the non-significant FTR group(+ -+ +, 68 cases) and the significant FTR group(≥+ + +, 68 cases). Outpatient follow-up with 24-72 hour dynamic electrocardiogram and transthoracic echocardiography(TTE) was conducted at 3, 6, 12, 24, and 36 months post-discharge. The maintenance of sinus rhythm and changes in FTR were compared between the two groups.Results:All patients successfully completed the Mei Mini Maze Procedure. Compared to preoperative values, the severity of FTR improved in both groups. Non-significant FTR group: 59% of patients(40 cases) had no regurgitation, 27%(18 cases) had mild FTR, 11%(8 cases) had moderate FTR, and 3%(2 cases) had severe FTR; significant FTR group: 19%(n=13) had no regurgitation, 25%(17 cases) had mild FTR, 25%(17 cases) had moderate FTR, and 31%(21 cases) had severe FTR. The Kaplan-Meier(KM) curve revealed that the sinus rhythm maintenance rate at 3 years post-surgery was significantly higher in the non-significant FTR group(72.06%) than in the significant FTR group (57.35%), with a statistically significant difference( P=0.011). Multivariate analysis showed that postoperative FTR ≥ moderate( HR=11.469), preoperative significant FTR( HR=1.206), age over 65 years( HR=3.734), non-paroxysmal AF( HR=2.346), and longer AF duration( HR=1.151) were risk factors for AF recurrence in this cohort. Conclusion:The recovery of sinus rhythm in AF patients is closely related to the severity of FTR. Patients with preoperative significant FTR had a lower rate of sinus rhythm maintenance after surgery. Both preoperative and postoperative significant FTR are risk factors for AF recurrence in AF patients with FTR. Therefore, for patients with significant FTR, simultaneous treatment of FTR during the surgery, including a standard Cox-Maze Ⅳ procedure, may be more beneficial for maintaining postoperative sinus rhythm.

OBJECTIVES: To conduct a comprehensive analysis of the global burden of diarrheal diseases in children under 5 years. METHODS: The data from the Global Burden of Disease (GBD) 2021 were analyzed to assess the incidence, mortality rates and average annual percentage changes (AAPC) of diarrhea among children under 5 years across nations(regions) and GBD regions from 1990 to 2021 using joinpoint regression. Smoothed curve regression was employed to explore the correlation of diarrheal disease burden with the Social Development Index (SDI) and for analyzing the burden of specific diarrheal pathogens. The Slope and Concentration Indices quantified disparities across SDI levels and the future trend were projected by the Bayesian Age-Period-Cohort (BAPC) model. RESULTS: From 1990 to 2021, the global incidence (AAPC: -3.65) and mortality (AAPC: -5.15) rates of diarrheal diseases declined steadily in children below 5 years. In 2021, neonates (<28 days) were the most affected, with an incidence rate of 138 058.74 per 100 000 and a mortality rate of 251.14 per 100 000. Rotavirus was the leading cause of death. The incidence rate of diarrheal diseases was negatively correlated with SDI, and the Concentration Index decreased from -0.293 in 1990 to -0.314 in 2021 without a significant gender difference. The BAPC model suggested that the global incidence rate of diarrheal diseases tends to decrease progressively from 2022 to 2050, with a predicted rate of 23 448.04 per 100 000 for male and 29 932.59 per 100 000 for female by 2050. CONCLUSIONS Despite the reduction in the global burden of diarrhea and the projection of its further decline, diarrheal diseases disproportionately affect neonates and low-SDI regions. While rotavirus remains the primary etiological agent worldwide, the predominant pathogens vary by nations (regions) and GBD regions, and strengthened interventions targeting vulnerable populations are needed.

Objective:To observe the effects of 0.01% atropine eye drops on ocular biometrics in myopic adolescents.Methods:A prospective cohort study was conducted.Two hundred and nineteen myopic adolescents who visited the First Affiliated Hospital of Zhengzhou University from June 2016 to June 2017 and completed the 1-year follow-up on time were enrolled.The 219 adolescents were divided into a 0.01% atropine+ single-vision spectacles (SV) group (119 cases) wearing single-vision spectacles with one drop of atropine eye drop applied to both eyes once nightly, and a simple SV group (100 cases) wearing SV only.Axial length (AL), corneal power and anterior chamber depth were measured with the IOLMaster.Lens power was calculated using the Bennett-Rabbetts formula.Intraocular pressure was measured by non-contact tonometry.Spherical equivalent (SE) was examined by cycloplegic autorefraction.Total astigmatism and corneal astigmatism were calculated by vector decomposition.The right eye data were analyzed to compare the ocular biometrics changes between the two groups, and multiple linear regression analysis was used to evaluate the influencing factors.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of First Affiliated Hospital of Zhengzhou University (No.2016-35). Written informed consent was obtained from guardians before any medical examination.Results:The SE change and AL elongation 12 months after treatment in 0.01% atropine+ SV group were (-0.47±0.45) D and (0.37±0.22) mm, respectively, which were significantly lower than (-0.70±0.60)D and (0.46±0.35)mm in simple SV group ( t=5.523, 9.651; both at P<0.001). There were significant differences in SE and AL between before and after treatment in both groups (SE: Fgroup=1.556, P=0.015; Ftime=12.538, P=0.002; AL: Fgroup=3.425, P=0.021; Ftime=18.235, P=0.008). The SE and AL at 4, 8 and 12 months after treatment were all increased in comparison with before treatment in both groups, showing statistically significant differences (all at P<0.001). The SE and AL at 8 and 12 months after treatment in 0.01% atropine+ SV group were smaller than in simple SV group, and the differences were statistically significant (all at P<0.001). At 8 and 12 months after treatment, total astigmatism and the anterior chamber depth were increased and the lens power was decreased in comparison with before treatment in both groups, and the differences were statistically significant (all at P<0.05). There was no significant difference in corneal astigmatism, corneal power and intraocular pressure at different time points before and after treatment between the two groups (all at P>0.05). In the multiple linear regression analysis, an equation of Δmyopic SE=-0.012-2.685×ΔAL-1.002×Δcorneal astigmatism-0.656×Δlens power+ 0.477×Δtotal astigmatism+ 0.363×Δanterior chamber depth-0.060×age+ 0.011×sex was used, showing the change of SE was mainly caused by the change of AL ( β=-2.685), then corneal power, lens power, total astigmatism and anterior chamber depth. Conclusions:In adolescents, 0.01% atropine eye drops can effectively retard myopia progression and axial elongation, showing no effect on astigmatism, corneal power, lens power, anterior chamber depth and intraocular pressure.The controlling effect of 0.01% atropine eye drops in the development of myopia is mainly achieved by reducing axial elongation.

Objective:To evaluate the efficacy and safety of non-osteotomy total hip arthroplasty (THA) in the treatment of Crowe IV developmental dysplasia of the hip (DDH).Methods:From Jan 2013 to Sep 2021, 46 patients (46 hips) in our department who underwent total hip arthroplasty without osteotomy for unilateral Crowe IV DDH were retrospectively analyzed, including 6 males and 40 females, with an average age of 41.2±7.2 years (25-61 years). The reduction of the femoral head was achieved successfully through moderate upward-posterior displacement of the movement center, gradual osteotomy of the calcar femorale, proper sinking of the femoral prosthesis and sufficient soft tissue release. The evaluation indexes included the basic condition of the operation (operation time, blood loss, blood transfusion, volume), clinical evaluation (Harris score of hip joint function, patient satisfaction, Trendelenburg sign), imaging evaluation (measurement of limb length and pelvic inclination) and incidence of complications.Results:The mean follow-up time was 72.2±8.8 months (8-101 months). The operation time was 97.2±12 min (84-112 min). The average intraoperative bleeding volume was 550±60 ml (350-850 ml). No patient had periprosthetic infection or fracture, no periprosthetic osteolysis or prosthesis loosening, and no patient needed revision surgery at the last follow-up of all cases. The average HHS score of patients increased from 42.5±12.3 points before surgery to 89.2±10.8 points at the last follow-up, and the difference was statistically significant ( t=19.35, P<0.001). Patient self-rated satisfaction: none was very dissatisfied, 1 patient were less satisfied (2%, 1/46), 4 patients were average (9%, 4/46), 19 patients were relatively satisfied (41%, 19/46), and 22 patients were very satisfied (48%, 22/46). The Trendelenburg sign of 46 cases was positive before operation, and all were negative at the last follow-up. The patients' true leg length discrepancy (LLD) measurement was -2.5±0.6 mm before surgery and 11.5±3.2 mm at the last follow-up ( t=29.17, P<0.05). Patients' perceived LLD was 28.2±5.1 mm before surgery and 3.4±1.4 mm at the last follow-up ( t=32.18, P<0.05). The length of the residual calcar femorale was 3.2±0.4 mm after THA. The limb extended distance of affected limb was 45.2±4.6 mm. The preoperative iliolumbar angle was -6.5°±2.3°, which returned to -0.5°±1.3° at the last follow-up ( F=651.97, P<0.05). Conclusion:For patients with unilateral type IV DDH, non-osteotomy THA is a safe and effective surgical method with simple operation and few complications. It can quickly correct pelvic tilt and lumbar compensatory scoliosis postoperatively.

Objective:To observe the safety and efficacy of 0.01% atropine eye drops in the prevention of myopia onset in schoolchildren.Methods:A randomized double-blind controlled study was conducted.Sixty Chinese Han children (60 eyes) with binocular spherical equivalent (SE) between + 0.50 D and -0.75 D (pre-myopia) by cycloplegic autorefraction treated in The First Affiliated Hospital of Zhengzhou University were enrolled from July to October 2020.Aged 6-12 years old, the children were divided into 0.01% atropine group and control group according to a random number table, with 30 cases (30 eyes) in each group.The children were given one drop of 0.01% atropine or placebo eye drops in both eyes once a night.The SE, axial length (AL), accommodative amplitude and pupil diameter were compared before and after 3-month, 6-month of treatment between the two groups.Discomforts were recorded.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of The First Affiliated Hospital of Zhengzhou University (No.2020-KY-286). Written informed consent was obtained from guardian of each subject.Results:After treatment, 26 and 25 subjects completed the 6-month follow-up in 0.01% atropine group and control group, respectively, among which 3 subjects in 0.01% atropine group accounting for 11.5% and 9 in control group accounting for 36.0% developed myopia, showing a statistically significant difference ( χ2=4.238, P=0.040). There were significant differences in the overall comparison of SE and AL at different time points between before and after treatment ( Ftime=10.981, 81.854; both at P<0.001). At 3 and 6 months after treatment, there were significant increases in the SE and AL of control group and AL of 0.01% atropine group compared with respective baseline values (all at P<0.05). There was no significant difference in SE at 3 and 6 months after treatment compared with baseline SE in 0.01% atropine group (both at P>0.05). At 6 months after treatment, the change in SE in 0.01% atropine group was (-0.15±0.26)D, which was significantly less than (-0.34±0.35)D in control group, and the change in AL in 0.01% atropine group was (0.17±0.11)mm, Which was significantly shorter than (0.28±0.14)mm in control group, with significant differences between them ( t=2.207, P=0.032; t=3.127, P=0.003). There were significant differences in pupil diameter at different time points between before and after treatment ( Ftime=2.263, P=0.032). At 3 and 6 months after treatment, the pupil diameter was increased in comparison with baseline in 0.01% atropine group (both at P<0.05). There were significant differences in accommodative amplitude at different time points between before and after treatment in the two groups ( Fgroup=0.882, P=0.042; Ftime=0.337, P=0.033). The accommodative amplitude at 3 and 6 months after treatment were decreased in comparison with baseline in 0.01% atropine group and control group at corresponding time points (all at P<0.05). Within a month after treatment, photophobia in bright sunlight occurred in 5 cases in 0.01% atropine group, accounting for 16.7%(5/30), and 2 cases in control group, accounting for 6.7%(2/30), showing no significant difference ( χ2=0.647, P=0.421). No near-vision blur and other uncomfortable symptoms was found in the two groups. Conclusions:After 6-month application of 0.01% atropine eye drops, the prevalence of myopia in pre-myopia schoolchildren decreases and the changing rate of SE and AL slows down.The accommodative amplitude is slightly reduced and pupil diameter is slightly increased, with no obvious effects on study and life.
