New-generation tetracyclines for severe macrolide-resistant Mycoplasma pneumoniae pneumonia in children: a retrospective analysis

BackgroundMacrolide-resistant Mycoplasma pneumoniae (MRMP) strains are increasingly prevalent, leading to a rise in severe Mycoplasma pneumoniae pneumonia incidence annually, which poses a significant threat to children’s health. This study aimed to compare the effectiveness and safety of oral minocycline and doxycycline for the treatment of severe MRMP pneumonia in children.MethodsThis retrospective analysis included children treated for severe MRMP pneumonia at the Pediatric Department of Tongji Hospital, Shanghai, China, between September 2023 and January 2024 using minocycline and doxycycline. The patients were divided into four groups according to treatment: oral doxycycline alone (DOX group), oral minocycline alone (MIN group), oral doxycycline with intravenous glucocorticoids (DOXG group), and oral minocycline with intravenous glucocorticoids (MING group). Student’s t-test, Mann–Whitney U test, and χ2 or Fisher’s exact tests were used for group comparisons.ResultsA total of 165 patients were included in this study: 84 received minocycline, and 81 received doxycycline. The DOX group had higher fever resolution rates within 24, 48, and 72 h compared to the MIN group (63.2% vs. 31.8%, 79.0% vs. 63.6%, and 100% vs. 90.9%, respectively; all p < 0.05). The DOXG group showed higher fever resolution rates within 24 and 48 h than the MING group (92.3% vs. 83.4%, 100% vs. 92.7%, all p > 0.05). There were no statistically significant differences in time to imaging improvement, cough improvement, and disappearance of wet rales between groups, regardless of glucocorticoid combination. The longer the duration of fever prior to tetracycline therapy, the greater the likelihood of hypoxemia (p = 0.039) and a greater than two-fold elevation in the D-dimer level (p = 0.004).Univariate binary logistic regression model analysis revealed that CRP and erythrocyte sedimentation rate at disease onset were associated with defervescence within 24 h after treatment with tetracyclines alone (p = 0.020, p = 0.027), with erythrocyte sedimentation rate also influencing defervescence within 48 h (p = 0.022).ConclusionDoxycycline treatment resulted in a higher rate of defervescence than minocycline. Prompt treatment reduced the probability of pleural effusion, hypoxemia, pulmonary atelectasis, and D-dimer levels > 2 times the reference value.

Upper- vs Lower-Extremity Secondary Access During Transcatheter Aortic Valve Implantation

An upper-extremity approach for secondary access during transfemoral transcatheter aortic valve implantation (TAVI) may reduce clinically relevant secondary access site-related bleeding. To investigate the safety and efficacy of an upper-extremity approach compared with a lower-extremity approach in patients undergoing TAVI. The TAVI XS trial was a randomized clinical trial performed between November 28, 2022, and November 15, 2023, with a 30-day follow-up, in 4 TAVI centers in the Netherlands. Eligibility was determined first, and only those patients with severe aortic stenosis and no contraindication for upper- or lower-extremity secondary access were informed about the study and asked to participate. Participants were randomized 1:1 between the upper-extremity approach (radial artery diagnostic access and upper-arm vein for temporary pacing lead placement) and lower-extremity approach (femoral artery diagnostic access and femoral vein for temporary pacing lead placement) for secondary access during TAVI. Primary end point was clinically relevant bleeding (Bleeding Academic Research Consortium type 2, 3, or 5) of the randomized secondary access. Secondary end points included any clinically relevant bleeding, time to mobilization, duration of hospitalization, secondary access failure, and procedural time. Of a total of 324 eligible patients, 238 patients undergoing transfemoral TAVI (mean [SD] age, 79.4 [6.5] years; 150 male [63.0%]; median European System for Cardiac Operative Risk Evaluation II score, 2.2% [IQR, 1.5%-3.5%]) were included. The primary end point occurred in 5 of 119 patients (4.2%) in the upper-extremity group and 16 of 119 (13.4%) in the lower-extremity group (odds ratio [OR], 0.28 [95% CI, 0.10-0.80]; P = .01). Incidence of any clinically relevant bleeding was decreased in the upper-extremity group (25 of 119 [21.0%] vs 41 of 119 [34.5%] patients; OR, 0.51 [95% CI, 0.28-0.91]; P = .02). There was no difference in time to mobilization or duration of hospitalization. Secondary access failure (14 of 119 [11.8%] vs 1 of 119 [0.8%] patients; OR, 15.73 [95% CI, 2.03-121.69]; P = .001) and procedural time (60.0 [IQR, 39.0-88.0; 95% CI, 53.0-70.0] vs 48.0 [IQR, 34.0-64.0; 95% CI, 40.0-55.0] minutes; P = .002) were higher in the upper-extremity cohort. In this randomized clinical trial of patients undergoing transfemoral TAVI, the upper-extremity approach for secondary access was associated with less clinically relevant access site-related bleeding compared with the conventional lower-extremity approach and should be considered to reduce periprocedural bleeding complications.

The impact of diurnal variations on emergence delirium following general anesthesia and surgery in children.

Emergence delirium (ED) is a widely recognized issue that prolongs mechanical ventilation and post-anesthesia care unit (PACU) resuscitation time, consequently increasing hospital costs and mortality. Postoperative disturbance in circadian rhythms, commonly leading to sleep disorders, has been identified as a significant risk factor for ED. However, the influence of surgery timing (morning vs. afternoon) on the incidence of ED in pediatric patients undergoing general anesthesia remains unknown. Patients aged 2-6 years who were operated on under general anesthesia with a bispectral index value between 50 and 60 were categorized based on anesthesia start time into either the morning surgery group (Group M, 8:00-12:00) or the afternoon surgery group (Group A, 13:00-17:00). The primary outcome was the post-extubation incidence of ED assessed by the Cornell Assessment of Pediatric Delirium (CAPD) score. Secondary outcomes included extubation time, duration of PACU stay, and adverse postoperative events and complications. We recruited a total of 560 patients, 280 in group M and 280 in group A. Compared to Group M, Group A exhibited a significantly higher incidence of ED (p < 0.001), elevated CAPD scores (p < 0.001), and prolonged PACU stays (p < 0.001). Notably, there was no significant difference in extubation time and anesthesia-related adverse events or other postoperative complications between the groups. Our study highlights that the time of surgery significantly affects the incidence of ED, CAPD scores, and PACU stay duration in children. Further validation of these findings may guide future strategies to reduce ED.

Analysis of mixed traffic flow characteristics based on cellular automata model under lane management measures

In the future, mixed traffic flow comprising Human-Driven Vehicles (HDVs), Connected and Autonomous Vehicles (CAVs), and CAV platoons will coexist for an extended period. Exploring the operational characteristics of mixed traffic flow under different lane management measures is essential for effective management and control. Initially, we analyze the motion characteristics of HDVs, CAVs, and CAV platoons and identify the car-following types within mixed traffic. Based on vehicle motion characteristics and the variance in maximum desired speeds among HDV drivers, we establish longitudinal motion rules for HDVs using a safety distance model. For CAVs and their platoons, we develop longitudinal motion rules by considering platoon merging and splitting behaviors, as well as speed and spacing error requirements for platoon driving. Subsequently, we formulate lateral lane-change rules based on the Symmetric Two-lane Cellular Automata (STCA) model, considering differences in reaction times and following distances between HDVs and CAVs. Finally, we conducted simulation experiments on a unidirectional three-lane highway using the multi-lane mixed traffic flow cellular automata model, analyzing the characteristics of mixed traffic under various lane management measures, such as mixed lane, CAV-dedicated lane, and CAV-priority lane. The results show that as the proportion of CAV (denoted as p) increases, the traffic flow capacity, optimal density, and jam density also increase. When p≤0.6, the k−q diagram exhibits a triangular shape, whereas for p>0.6, it assumes a trapezoidal shape. Implementing CAV-dedicated lane can reduce Cooperative Adaptive Cruise Control (CACC) degradation rates but only enhances traffic flow capacity when the CAV proportion reaches a certain threshold. Compared to the mixed lane scheme, when p≤0.3 and k≤0.3, the CAV-priority lane schemes not only meet traffic demands but also reduce CACC degradation rates. The vehicle speed in CAV-priority lane surpasses that in HDV lanes, facilitating improved traffic efficiency for CAVs. The distribution of maximum speeds among HDV drivers affects the fundamental diagram of mixed traffic flow and the performance of CAV-priority lane, with greater impacts observed as the standard deviation of the HDVs' maximum speed increases.

Subcutaneous fast-acting insulin analogues ± long-acting insulin vs IV insulin infusion in DKA: updated meta-analysis of randomised trials.

Diabetic ketoacidosis (DKA) is often treated with intravenous regular insulin infusion (IVRII). Subcutaneous fast-acting insulin analogues (FAIAs); either alone or combined with subcutaneous long-acting insulin (LAI); might be useful to treat DKA. Our meta-analysis updated on their benefits and safety in DKA. We searched major electronic databases for randomised trials on subcutaneous FAIAs ± subcutaneous LAI vs IVRII in DKA. Primary outcomes were all-cause in-hospital mortality, time to resolution of DKA and hyperglycemia, in-hospital DKA recurrence and hospital readmission for DKA post-discharge. Secondary outcomes included resource utilisation and patient satisfaction. Safety outcomes were adverse events. Reviewers assessed risk of bias and quality of evidence using GRADE. We performed a priori subgroup and trial sequential analyses on primary outcomes. Seven trials enrolled 351 mainly adult patients (255/351) with mild to moderate DKA. No trials studied subcutaneous FAIA and subcutaneous LAI. Their risk of bias was high or unclear in several domains. No all-cause in-hospital mortality and DKA recurrence were reported. No trial investigated hospital readmission for DKA post-discharge. There was no difference in mean time to resolution of DKA (mean difference = -0.70, 95% CI -2.18 to 0.79 h, p = 0.36) or hyperglycemia [blood glucose < 250 mg/dL (13.9 mmol/L)] (mean difference = -0.17, 95% CI -1.10 to 0.76 h, p = 0.72) between subcutaneous FAIA and IVRII groups. There were largely no subgroup effects. Both groups had similar secondary outcomes. Hypoglycemia was the most common adverse event. Quality of evidence was low to very-low for all outcomes. The only possible trial sequential analysis for time to resolution of DKA was inconclusive. There was low- to very-low quality evidence that subcutaneous FAIA did not affect patient-centered outcomes in mainly adult patients with mild to moderate DKA compared to IVRII.

Impact of medical adhesives on persistent fluid extravasation at needle injection sites in patients with severe edema: a randomized controlled trial.

To investigate the efficacy of medical glue in halting fluid extravasation at needle insertion sites in patients with severe edema. Sixty patients with severe edema were recruited between June 2022 and June 2023 and randomly allocated into either the control group or the experimental group, with 30 cases in each. In the experimental group, after intramuscular injection, medical glue was administered at the needle insertion site, and covered with gauze dressing upon curing, and subsequently subjected to pressure bandaging. Patients were instructed to limit their activity. Meanwhile, the control group received conventional nursing procedures involving pressure bandaging and activity restriction. The effectiveness of nursing interventions in halting exudation, duration of hospitalization, duration of exudation, nursing expenses, skin complications (infection, rash, abrasion, abnormal sensation, etc.), and patient satisfaction with nursing care were monitored. Comparison between the two groups revealed statistically significant differences in several aspects: the success rate of halting exudation, duration of exudation, total skin complication rate, and overall satisfaction [83.3% vs. 20.0%, (2.20 ± 2.76) days vs. (7.33 ± 3.28) days, 6.67% vs. 33.33%, 80.00% vs. 36.67%, P < 0.05]. However, there were no statistically significant differences in hospitalization time and nursing expenses [(14.50 ± 5.17) days vs. (14.00 ± 3.95) days, (537.53 ± 264.19) yuan vs. (661.97 ± 305.55) yuan, P > 0.05]. Medical glue demonstrates effectiveness in halting fluid extravasation at needle insertion sites among patients experiencing severe edema. Additionally, it reduces the duration of exudation, diminishes skin complications resulting from exudation, and significantly enhances patient satisfaction with nursing care. Given these benefits, its clinical adoption and application are highly recommended.

A prospective randomized study on the efficacy of real-time dynamic navigation in deep horizontal mandibular third molar extractions

PurposeThis study aimed to evaluate the clinical efficacy of applying real-time dynamic navigation (RDN) in the extraction of deep horizontal mandibular impacted third molars, hypothesizing that RDN reduces surgical time and minimizes the risk of injury to adjacent anatomical structures.MethodsA prospective study was conducted on 160 patients aged between 18 and 37 years with deep horizontal impaction of the mandibular third molar. The participants were randomly assigned to either the experimental group (receiving RDN-assisted extractions) or the control group (undergoing traditional extraction methods). Preoperative planning utilized cone beam computed tomography (CBCT) and Mimics software for the accurate localization and segmentation of impacted teeth. Parametric data were analysed via an independent t test for intergroup comparisons, and significance was set to p < 0.05.ResultsIn the experimental group, an average of 11 ± 1 min was required for preoperative planning via RDN, which was not required in the control group. The setup of the navigation system took an average of 4 ± 1 min in the experimental group and 0 min in the control group. The experimental group demonstrated a significantly shorter average surgical time (22 ± 3 min) than did the control group (36 ± 3 min). The differences in the preoperative design time, surgical time, and complication rates between the two groups were statistically significant (p = 0.005). Additionally, the RDN group reported no complications related to adjacent tooth damage or nerve injury.ConclusionThe precision, safety, real-time guidance of RDN supports its use in complicated dental extractions, which would introduce a new era of oral and maxillofacial surgery.Graphical

Inducting the Socratic Method of Forming Faith in African Contexts

The Socratic method of questioning and answering as a learning and teaching strategy has been used widely over time, for it effectively stimulates meaningful learning. Its learner-centered and transformative nature promotes ongoing dialogue. Since cultural differences influence the nature of questions asked, induction of the Socratic method is inevitable so that faith formation leads to thinking theologically where faith becomes a contextual form of thinking and thinking a form of contextualized faith. Some mainline churches in Africa have adopted catechisms with pre-asked and pre-answered questions formulated in Europe between the sixteenth and eighteenth centuries. The challenges of time, culture, and geographical contextual differences create a gap between the church’s faith formation and context-based spiritual quests. These gaps demand asking the right questions that challenge and inverse wrong attitudes that foster deep reflective self-evaluation, interpretation, and understanding, shaping appropriate perceptions to address the contemporary spiritual quests of Africa. Using the qualitative literature review methodology, this article discovered that there are some gaps between questions and answers in catechisms used in mainline churches and contemporary spiritual quests of Africa. This article aims to discuss the means of closing the gap between questions and answers in catechism and context-based spiritual quests. It recommends induction of the Socratic method so that the questions and answers in catechisms are contextual, communicable, assimilable, and appropriable in African contexts. This study contributes to faith formation by recommending the induction of the Socratic method so that the questions and answers in catechisms are contextual, communicable, assimilable, and appropriable in African contexts.

The effects of pulsed electromagnetic field therapy on muscle strength and pain in patients with end-stage knee osteoarthritis: a randomized controlled trial.

Osteoarthritis (OA) of the knee is one of the most common chronic degenerative joint conditions affecting aging population. To investigate the effectiveness of a combination of home-based exercise and pulsed electromagnetic field (PEMF) therapy to improve muscle strength, physical function, and pain. Sixty patients were randomly assigned to either home-based exercise alone (control group; n = 30) or combined with PEMF therapy (treatment group; n = 30) twice a week for eight weeks. Knee extension, flexion muscle strength, gait speed (GS), 5 time sit-to-stand test (5STS), Visual Analogue Scale (VAS) pain and Knee Injury and Osteoarthritis Outcome Score (KOOS) were recorded at baseline and 4 and 8 weeks. Significant improvements in symptomatic knee extension muscle strength (SKE, p = 0.001), flexion strength (SKF, p = 0.011), contralateral knee extension muscle strength (CKE, p = 0.002), and flexion strength (CKF, p = 0.009) were observed for the PEMF treatment group at 8 weeks. Significant reductions in VAS pain scores were observed in both the treatment (p < 0.001, partial η2 = 0.505) and control (p < 0.001, partial η2 = 0.268) groups. Significant differences were reported between groups in the 4 (p = 0.010, partial η2 = 0.111) and 8 (p = 0.046, partial η2 = 0.068) week assessment in VAS pain. A significant time difference was found in GS and 5STS between baseline and week 8 (GS: difference 0.051, p = 0.026; 5STS: difference 2.327, p < 0.001) in the treatment group. The significant group difference at week 8 was observed in SKE (p = 0.013) in female patients while pain in male patients (p = 0.026). Patients aged over 70 years have a significantly superior improvement in SKE, SKF, and CKF after 8 weeks of PEMF therapy. The combination of PEMF therapy and home-based exercise superiorly improved knee muscle strength and reduced pain in end-stage knee OA subjects and showed a promising tendency to improve performance-based physical function. PEMF therapy was shown to preferentially benefit knee muscle strength in female patients and patients aged over 70 years, whereas male patients were more responsive to PEMF therapy in the form of pain relief. clinicalTrials.gov, NCT05550428.

Identical Parallel Machine Scheduling to Minimize Makespan Using Suggested Algorithm Method at XYZ Company

XYZ company produce the various shape of motor spare parts product. The company has threeidentical parallel spot welding machines that use a random method of production scheduling, basedon machine capacity without any sequence of jobs, and only use daily production targets given tooperators. Based on the data, the actual scheduling of the machines has a very large completion timedifference between each machine, or the machine loading is uneven. As a result, the makespanbecomes longer with a value of 440000 seconds (26 days). This research aims to minimize the existingmakespan by giving proposed scheduling, using the suggested algorithm method, which has a smallnumber of iterations and has an optimal result. The method begins with the longest processing timesequence rule which is used as the upper bound for the first iteration, then continued to calculate thelower bound and machine workload. The calculation stops at the 15th iteration because the completiontime value exceeds the lower and upper bound so that the optimal scheduling taken is scheduled inthe 14th iteration with a makespan value of 914412 seconds (16 days). The proposed scheduling canminimize the makespan from the actual schedule by 38%.

Constructing Lyapunov–Krasovskii functionals for linear positive continuous time difference systems

Abstract In this paper, a linear positive functional difference system with discrete and distributed delays is studied. It is proved that if the considered system is exponentially stable, then it admits both linear and diagonal quadratic Lyapunov–Krasovskii functionals. In addition, new exponential stability conditions for switched linear positive functional difference systems are obtained on the basis of a constructive approach to the design of common Lyapunov–Krasovskii functionals for the associated families of subsystems.

Quantifying the Impact of C7 Spinal Nerve Harvest on Spontaneous, Patient-Initiated Movement of the Donor Upper Extremity.

Transfer of a healthy C7 spinal nerve is a tool for upper extremity reanimation in patients with severe brachial plexus injury (BPI). Its use remains controversial owing to concern for neurological injury to the donor arm. Utilizing wearable motion-sensor technology, we aimed to quantify donor arm morbidity after C7 spinal nerve harvest in patients with pan-BPI, reporting both the time and magnitude of donor arm movement in a real-world setting compared to healthy controls. Seventeen patients who underwent contralateral C7 (CC7) transfer for traumatic pan-BPI at least 2 years prior were compared to 14 healthy controls. Each participant wore an accelerometer on both arms for 7 consecutive days. The vector time (VT), or time of movement measured in hours/day, and the vector magnitude (VM), or magnitude of arm movement measured as a single vector magnitude per second, were collected and compared between groups. The correlation between VT and VM and time from C7 spinal nerve harvest was also calculated. At mean 7.7 years after C7 spinal nerve harvest, there was no difference between donor and control arms for VT (5.76±1.55] vs 5.45±1.22 hours, P = 0.56) or VM (2242236±753853 vs 1919223±579723 activity counts, P = 0.20), regardless of donor arm dominance. The C7 harvest cohort used the injured arm 53% of the time and with 27% of the power of the donor arm. There was no significant difference in time or magnitude of arm movement between donor arms and the arms of healthy controls.

Towards complexity in de Sitter space from the doubled-scaled Sachdev-Ye-Kitaev model

How can we define complexity in dS space from microscopic principles? Based on recent developments pointing towards a correspondence between a pair of double-scaled Sachdev-Ye-Kitaev (DSSYK) models/ 2D Liouville-de Sitter (LdS2) field theory/ 3D Schwarzschild de Sitter (SdS3) space in [1–3], we study concrete complexity proposals in the microscopic models and their dual descriptions. First, we examine the spread complexity of the maximal entropy state of the doubled DSSYK model. We show that it counts the number of entangled chord states in its doubled Hilbert space. We interpret spread complexity in terms of a time difference between antipodal observers in SdS3 space, and a boundary time difference of the dual LdS2 CFTs. This provides a new connection between entanglement and geometry in dS space. Second, Krylov complexity, which describes operator growth, is computed for physical operators on all sides of the correspondence. Their late time evolution behaves as expected for chaotic systems. Later, we define the query complexity in the LdS2 model as the number of steps in an algorithm computing n-point correlation functions of boundary operators of the corresponding antipodal points in SdS3 space. We interpret query complexity as the number of matter operator chord insertions in a cylinder amplitude in the DSSYK, and the number of junctions of Wilson lines between antipodal static patch observers in SdS3 space. Finally, we evaluate a specific proposal of Nielsen complexity for the DSSYK model and comment on its possible dual manifestations.

Comparison of the efficacy of medial tarsal venous flaps and traditional venous/arterial free flaps in the reconstruction of hand soft tissue defects: A new type of physiological flap.

The treatment of hand soft tissue defects primarily relies on flap reconstruction. However, traditional venous/arterial free flaps have several disadvantages, including damage to the donor site, bruising, discoloration, blister formation, and even necrosis. These issues can significantly impact patient recovery and outcomes. Therefore, there is a need for alternative approaches that minimize these complications and improve overall patient care. To compare the efficacy of medial tarsal venous flaps and traditional venous/arterial free flaps in the reconstruction of hand soft tissue defects, evaluating various clinical outcomes and patient recovery metrics. We screened 30 suitable patients with hand soft tissue defects and randomly assigned them to three groups. Patients in each group were transplanted with either medial tarsal free venous flaps or traditional arterial/venous free flaps to achieve coverage and reconstruction of the soft tissue defects. The results were compared and analyzed using the following metrics: operation time, survival rate, complication rate, pain index, postoperative infection rate, and functional evaluations of both the donor and recipient areas. There was no significant difference in operation time between the medial tarsal free venous flaps and the traditional forearm free venous flaps. The operative time for both types of flaps was shorter than that of the traditional free fibular flap from the hallux. The survival rate of the medial tarsal free venous flaps was comparable to that of the fibular free arterial flaps from the great toes and significantly higher than that of the traditional forearm free venous flaps. The complication rate showed an inverse trend to the survival rate of the flaps. In terms of pain, the pain index for the medial tarsal free venous flaps was significantly lower than that of the fibular free arterial flaps from the hallux and comparable to that of the forearm free venous flaps. Regarding postoperative infection rates, the forearm free venous flap had the highest rate, while there was no significant difference between the medial tarsal free venous flaps and the fibular free arterial flaps from the great toes. The functional recovery of the medial tarsal free venous flaps was good in both the donor and recipient areas. There was no poor functional performance in the donor areas of the fibular free arterial flaps from the hallux or the recipient areas of the forearm free venous flaps. The medial tarsal free venous flaps effectively avoid the disadvantages of traditional venous and arterial free flaps, combining their advantages. These flaps offer shorter operative times, higher survival rates, and lower pain indices. They also provide excellent functional recovery in both donor and recipient areas. Thus, medial tarsal free venous flaps represent an ideal solution for reconstructing hand soft tissue defects.

Acupuncture Enhances Quality of Life and Disease Control in Chronic Spontaneous Urticaria Patients on Omalizumab: A Study of 61 Cases.

BACKGROUND Chronic urticaria (CU) is a skin condition causing itchy hives that can significantly impact quality of life. While medications like omalizumab can help, some patients may seek additional relief. This study aimed to investigate the potential benefits of acupuncture, a traditional Chinese medicine practice, as an adjunctive therapy alongside omalizumab for CU patients. MATERIAL AND METHODS We enrolled 31 CU patients who received acupuncture in addition to omalizumab (study group) and 30 CU patients who received omalizumab only (controls). Mean scores of each CU-Quality of life (QoL) and urticaria control test (UCT) scores after acupuncture were compared with the pre-acupuncture scores and with the scores of the controls. RESULTS There was no significant difference in mean food limitation, symptom embarrassment, cosmetics, and sports scores before and after acupuncture (P>0.005). Other CU-QoL scores were significantly lower after acupuncture compared to pre-acupuncture scores (P<0.005). Mean total CU-QoL score was significantly lower (P<0.001) and mean UCT score was significantly higher (P=0.001) after acupuncture compared to pre-acupuncture scores. There was no significant difference in free time, falling asleep, waking up at night, tiredness, concentration, symptom embarrassment, public embarrassment, cosmetics, clothing limitation, and sports scores between the acupuncture and control groups (P>0.005). Other CU-QoL scores were significantly lower in the acupuncture group compared to the controls (P<0.005). Mean total CU-QoL score was significantly lower (P=0.006) and mean UCT score was significantly higher (P<0.001) in acupuncture group compared to the controls. CONCLUSIONS Acupuncture is an effective adjunctive therapy for CU patients already receiving omalizumab, and can improve quality of life and disease control in these patients.

Short-term effectiveness of robot-guided femoral neck system combined with cannulated compression screw fixation in treatment of femoral neck fracture in young and middle-aged patients

To investigate short-term effectiveness of robot-guided femoral neck system (FNS) combined with cannulated compression screw (CCS) fixation in treatment of femoral neck fracture in young and middle-aged patients. A clinical data of 49 young and middle-aged patients with femoral neck fractures, who met the selection criteria and admitted between January 2021 and June 2023, was retrospectively analyzed. After reduction of femoral neck fractures, 27 cases were treated with robot-guided FNS fixation (FNS group) and 22 cases with robot-guided FNS and CCS fixation (FNS+CCS group). There was no significant difference in baseline data such as gender, age, cause of fracture, time from fracture to operation, fracture side, and classification (Garden classification and Pauwels classification) between the two groups ( P>0.05). The operation time, intraoperative blood loss, intraoperative fluoroscopy frequency, the time when the patient began bearing weight, and hip joint pain and functional scores (VAS score and Harris score) at last follow-up for two groups were recorded. Imaging re-examination was taken to evaluate the quality of fracture reduction, fracture healing, as well as the occurrence of fracture non-union, osteonecrosis of the femoral head, and femoral neck shortening. All operations were successfully completed and the incisions healed by first intention. There was no significant difference in operation time and intraoperative blood loss between the two groups ( P>0.05), and the intraoperative fluoroscopy frequency in FNS+CCS group significantly increased compared to FNS group ( P<0.05). All patients were followed up 12-18 months (mean, 14.1 months). Imaging re-examination showed that there was no significant difference in fracture reduction quality between the two groups ( P>0.05), but the fracture healing time was significantly shorter in FNS+CCS group than in FNS group, and weight-bearing began earlier ( P<0.05). The incidences of femoral neck shortening, fracture non-union, and osteonecrosis of the femoral head were lower in FNS+CCS group than in FNS group, and there was significant difference in the incidence of femoral neck shortening between groups ( P<0.05). At last follow-up, there was no significant difference in VAS scores between the two groups ( P>0.05). However, the Harris score was significantly higher in FNS+CCS group than in FNS group ( P<0.05). Compared with FNS fixation alone, robot-guided FNS combined with CCS fixation in the treatment of femoral neck fractures in young and middle-aged patients has obvious advantages in terms of early weight bearing and fracture healing, improves fracture healing rate, effectively prevents postoperative complications, and can obtain good short-term effectiveness.

Comparison of ERCP Outcomes and Complication Risk between Elderly and Younger Patients: A Large Single-Center Study

Objectives: The current study compared potential risks, complications, and the impact on clinical outcomes among elderly and younger patients undergoing endoscopic retrograde cholangiopancreatography (ERCP). Methods: Procedure-related complications, risk factors, and clinical outcomes following complications in elderly patients (aged ≥75 years) and younger who underwent biliary ERCP were evaluated. Results: Median age of 63 (48–74) of 1164 patients who underwent biliary ERCP for the first time, and 266 (22.8%) were elderly. Comorbidities were statistically significant (81 [30.5%] versus 78 [8.7%], p &lt; 0.001), and periampullary diverticulum (PAD) was detected more commonly in the elderly group (79 [29.7%] vs. 103 [11.5%], p &lt; 0.001). There was no statistical difference in cannulation technique, cannulation time, and cannulation success in both groups, while the total ERCP procedure time was higher in the elderly group (22 [16–29] vs. 20 [14–29], p = 0.030). Regarding the procedure-related complications, there was no statistically significant difference between the two groups (26 [9.8%] vs. 71 [7.9%], p = 0.292). In the case of complications, the length of hospitalization stay was statistically longer in the elderly group. Moreover, the elderly had a longer length of hospitalization, experiencing pancreatitis and a higher probability of developing moderate/severe pancreatitis. In multivariate and univariate analysis, prolonged cannulation time was found to be an independent risk factor in patients ≥75 years of age. Conclusions: This study showed that while ERCP-related complication rates in elderly patients are comparable to younger patients, it can be associated with worse outcomes following the complication and prolonged length of hospitalization.

Single versus dual fixation of distal femur fractures: A retrospective cohort study at a level one trauma centre in New Zealand

Background The study compares single versus combination fixation of distal femur fractures. Method We retrospectively reviewed patients over 60 between January 2016 and December 2022. Union rate, ambulatory status and complication rate were primary outcomes. Secondary outcomes included quality of reduction, operative time and rate of blood transfusion. Results A total of 92 patients received single fixation, and 22 patients received combination fixation. There was no difference in rate or time of fracture union. Patients with dual fixation were allowed to weight bear on discharge significantly more than single fixation patients (50% vs. 18.9%, p = 0.003). Intramedullary nail fixation, as a single method or combined with lateral plating, was associated with earlier weight bearing. Immediate post-operative weight bearing significantly increased the likelihood of discharging to home or rehabilitation versus discharging to a transitional care facility ( p &lt; 0.00001). There was no difference in the rate of blood transfusion, complication or mortality. Medial translation of the distal articular block was significantly lower with dual fixation (1.2% vs. 3.4%, p = 0.021). Operation time was longer with combination fixation (183 min vs. 134 min p &lt; 0.001). Conclusion Combination fixation allows earlier weight bearing, at the cost of longer operation time.

Efficacy and Safety of Ciprofol Versus Propofol as Anesthetic for Patients Undergoing Painless Colonoscopy.

Ciprofol is a novel propofol analogue with a characteristic of hemodynamic stability. At present, there is a lack of research comparing the hemodynamic stability of ciprofol and propofol during painless colonoscopy. In this study, we aim to test the hypothesis that ciprofol is superior to propofol in terms of hemodynamic stability for sedation anesthesia in patients undergoing colonoscopy. A total of 222 patients were randomized into two groups. Patients in group P (n=112) and group C (n=110) received propofol and ciprofol sedation, respectively. Noninvasive blood pressure were monitored starting from induction (T0) to the end of the procedure, at 2-min intervals (T1 to T10). Heart rate variability (HRV), pain injection, Modified Observer's Assessment of Alertness and Sedation(MOAA/S) score, body movement, doses of norepinephrine, modified Aldrete score, drug-related adverse reactions, and patient satisfaction and endoscopist satisfaction were recorded. In group C, fewer patients experienced a decrease in blood pressure with a higher HRV after induction sedation, the incidence of pain injection was reduced, the amount of norepinephrine dose was decreased, patient satisfaction was increased compared with group P (all P<0.05). There were no significant differences in induction time, modified Aldrete score, alertness time, drug-related adverse reactions, and endoscopist satisfaction. Our study indicated intravenous induction with ciprofol was superior, with regard to hemodynamic stability and reduced injection pain, than induction with propofol for anesthesia in patients undergoing painless colonoscopy.

American emergency room wait times for psychiatric conditions from 2019 to 2021

Use of Emergency Departments (EDs) for psychiatric complaints has increased significantly in past decades. The onset of the COVID-19 pandemic saw large shifts in ED usage, with a relative increase in mental health complaints in EDs. This paper will investigate the difference in ED wait times for psychiatric and non-psychiatric complaints over this period. Utilized National Hospital Ambulatory Medical Care Survey (NHAMCS), from 2019 to 2021, for average wait times for psychiatric versus non-psychiatric complaints. Compared the average wait times for psychiatric complaints by region, triage status, and ICD-10 F code. There was no significant difference in the average wait times overall between these conditions (P = 0.57). People with schizophrenia or psychosis had a significantly higher wait time (P = 0.03) compared to mental health symptoms secondary to physiologic conditions. Northeastern American EDs also had prolonged wait times for psychiatric conditions (P &lt; 0.01) Research into factors of prolonged wait times can advise quality improvements such as the implementation of evidence-based triage and workup tools, and directed psychiatric education.
