Challenges and opportunities in human dimensions behind cat-wildlife conflict.

Because global anthropogenic activities cause vast biodiversity loss, human dimensions research is essential to forming management plans applicable to biodiversity conservation outside wilderness areas. Engaging public participation is crucial in this context to achieve social and environmental benefits. However, knowledge gaps remain in understanding how a balance between conservation and public demands can be reached and how complicated sociocultural contexts in the Anthropocene can be incorporated in conservation planning. We examined China's nationwide conflict between free-ranging cats (owned cats that are allowed to go outdoors or homeless cats living outdoors) and wildlife to examine how a consensus between compassion and biodiversity conservation can help in decision-making. We surveyed a random sample of people in China online. Over 9000 questionnaires were completed (44.2% response). In aggregate, respondents reported approximately 29 million free-ranging owned cats and that over 5 million domestic cats per year become feral in mainland China. Respondents who were cat owners, female, and religious were more likely to deny the negative impacts of cats on wildlife and ongoing management strategies and more supportive of stray cat shelters, adoption, and community-based fund raising than nonowners, male, and nonreligious respondents (p < 0.05). Free-ranging cat ownership and abandonment occurred less with owners with more knowledge of biodiversity and invasive species than with respondents with less knowledge of these subjects (p < 0.05). We recommend that cat enthusiasts and wildlife conservationists participate in community-based initiatives, such as campaigns to keep cats indoors. Our study provides a substantially useful framework for other regions where free-ranging cats are undergoing rapid expansion.

Retos y oportunidades de las dimensiones humanas detrás del conflicto entre gatos y fauna Resumen Debido a que las actividades antropogénicas globales causan una enorme pérdida de la biodiversidad, la investigación sobre las dimensiones humanas es esencial para generar planes de manejo aplicables a la conservación de la biodiversidad fuera de las áreas silvestres. Es muy importante lograr que el público participe en este contexto para obtener los beneficios sociales y ambientales. Sin embargo, todavía existen vacíos en el conocimiento sobre cómo lograr el balance entre la conservación y las demandas públicas y cómo incorporar los contextos socioculturales complejos del Antropoceno a la planeación de la conservación. Analizamos el conflicto nacional entre los gatos libres (gatos callejeros o gatos domésticos que se les permite salir) y la fauna en China para estudiar cómo un consenso entre la compasión y la conservación de la biodiversidad puede ayudar en la toma de decisiones. Encuestamos en línea a una muestra aleatoria de personas en China. Se completaron más de 9000 cuestionarios (44.2% de respuesta). En total, los respondientes reportaron un aproximado de 29 millones de gatos libres y que más de cinco millones de gatos domésticos se vuelven ferales al año en China. Quienes respondieron y son dueños de gatos, mujeres y religiosos tuvieron la mayor probabilidad de negar los impactos negativos de los gatos sobre la fauna y de las estrategias actuales de manejo y de mostrar más apoyo por los refugios de gatos abandonados, la adopción y de la recaudación de fondos comunitaria que quienes no son dueños, no son religiosos y son hombres (p < 0.05). La propiedad de gatos libres y el abandono ocurrieron menos con los dueños con más conocimiento sobre la biodiversidad y las especies invasoras que con los respondientes con menos conocimiento sobre estos temas (p < 0.05). Recomendamos que los aficionados a los gatos y los conservacionistas de la fauna participen en las iniciativas comunitarias; por ejemplo, campañas para mantener a los gatos dentro de casa. Nuestro estudio proporciona un marco sustancialmente útil para otras regiones en donde los gatos libres se encuentran en rápida expansión.

The therapeutic effect of concentrated growth factor gel on skin wounds with bone or tendon exposure.

Treatment of soft tissue wounds with bone or tendon exposure remains a tough clinical challenge for surgeons. The current clinical approaches include various types of flap reconstruction and artificial dermis grafting as well as negative pressure wound therapy (NPWT), which are time-consuming and often result in graft failure or significant scarring. Concentrated growth factor (CGF) is a novel blood extract that contains many growth factors, platelets and fibrin to promote an orderly healing process. However, few reports have focused on wounds with bone or tendon exposure. We present a limited series and two specific cases of skin wound with bone or tendon exposed that received surgical debridement followed by CGF treatment. CGF appeared to facilitate wound closure effectively and also reduced scar formation. Our findings provide a novel therapeutic option for refractory wounds with bone or tendon exposure.

Comparison between screw fixation and plate fixation via sinus tarsi approach for displaced intra-articular calcaneal fractures: a systematic review and meta-analysis.

BACKGROUND: Optimal surgical fixation for displaced intra-articular calcaneal fractures (DIACF) remains a subject of debate, particularly regarding the superiority between screw fixation and plate fixation via the sinus tarsi approach (STA). This review aims to determine the preferred treatment for DIACF and compare the outcomes of minimally invasive surgery options. METHODS: Our study involved thorough searches across multiple electronic databases, including PubMed, Cochrane, Embase, and Web of Science, to identify all relevant publications on distal intra-articular fractures of the calcaneus (DIACFs) that were fixed using cannulated screws or plates via STA. Through a comprehensive meta-analysis, we evaluated several outcomes, including post-operative function, radiological measurements, and complications. RESULT: A total of 728 patients from 7 studies met the inclusion criteria. Among them, 435 patients underwent screw fixation via STA, and 373 patients underwent plate fixation via STA. The study found no statistically significant differences between the screw fixation and the plate fixation via sinus tarsi approach (STA) in terms of AOFAS scores, Bohler's angle, Gissane's angle, sural nerve injury, secondary subtalar arthrodesis and reoperation. Compared with screw fixation, plate fixation via STA can reduce reduction loss of Bohler's angle (WMD = - 1.64, 95% CI = [- 2.96, - 0.31], P = 0.06, I2 = 59%), lower the incidence of fixation failure (OR = 0.32, 95% CI = [0.13, 0.81], P = 0.78, I2 = 0%), and decrease intra-articular step-off (WMD = - 0.52, 95% CI = [- 0.87, - 0.17], P = 0.66, I2 = 0%). CONCLUSIONS: Plate fixation demonstrates superior capability in restoring calcaneal width, maintaining Bohler's angle, and minimizing intra-articular step-off, thereby maintaining better reduction of the subtalar articular surface. In addition, plate fixation exhibits the modest complication rate and a low incidence of fixation failure. Therefore, we recommend the use of plate fixation through the STA, especially for complex and comminuted intra-articular calcaneal fractures.

Characteristics of drug-involved black women under community supervision; implications for retention in HIV clinical trials and healthcare.

This study examined retention and its relationship to mental health, substance use, and social determinants of health in a randomized clinical trial of a behavioral HIV/sexually transmitted infection prevention intervention with drug-involved Black women (N = 348) under community supervision programs in New York City. Using secondary analysis, we used logistic models to test the association between factors related to mental health, substance use, and social determinants of health and follow-up assessment completion (three, six, and 12 months). Participants who were diagnosed with schizophrenia had lower odds of retention. Participants who misused prescription opiates during their lifetime or food insecure in the past 90 days had higher odds of retention throughout the intervention.

Diffuse calcification of pancreas impairs endocrine function and predicts poor outcome in total pancreatectomy with islet autotransplantation.

In patients with chronic pancreatitis, pancreatic calcification is a risk factor for diabetes development, poor islet yield, and metabolic outcomes after total pancreatectomy with islet autotransplantation (TPIAT). We investigated whether calcification pattern based on computed tomography is associated with outcomes using our database of 200 consecutive TPIAT procedures. Three groups were compared: noncalcification (NC); focal calcification, limited to the pancreas head, body, or tail; and diffuse calcification (DC), with calcification in >2 sections. Maximum changes in outcomes were seen in the DC vs focal calcification group. In the DC group, preoperative hemoglobin A1c levels were higher (P < .01), and stimulated C-peptide levels were lower (P < .01) than in the NC group. Islet isolation from the DC pancreas resulted in the lowest islet equivalent (IEQ) yield and IEQ/kg among the 3 groups (P < .0001), with no insulin independence 12 months posttransplant (P < .05 vs NC group). Notably, at 12 months, the DC group was 91.7% narcotic-free, significantly higher than the NC group (P < .05). Although DC is a sign of diabetes risk after TPIAT, the DC group showed exceptional pain relief. These findings suggest that TPIAT can be beneficial for patients with chronic pancreatitis with severe calcification.

Global Research Hotspots in Venous Thromboembolism Anticoagulation: A Knowledge-Map Analysis from 2012 to 2021.

Background: Venous thromboembolism (VTE) is a common cardiovascular disease that seriously threatens human lives. Anticoagulant therapy is considered to be the cornerstone of VTE treatment. An increasing number of studies has been updated in the VTE anticoagulation field. However, no bibliometric analyses have assessed these publications comprehensively. Therefore, our study aimed to analyze the global status, hotspots, and trends of anticoagulant therapy for VTE. Methods: The relevant literature on VTE anticoagulation published between 2012 and 2021 was retrieved and collected from the Web of Science Core Collection database. VOSviewer, Cooccurrence Matrix Builder, gCLUTO, and some online visualization tools were adopted for bibliometric analysis. Results: A total of 15,152 related articles were retrieved. In recent years, the research output of VTE anticoagulation gradually increased. The United States was the most productive country. International cooperation is concentrated in North America and Europe; the most influential documents, journals, authors, and organizations were also from these two continents. Research hotspots mainly focus on clinical guidelines, VTE in special populations, non-vitamin K oral anticoagulants (NOACs), and parenteral anticoagulation. The research frontiers and trends include the assessment of NOACs and the antithrombotic management of VTE complicated with coronavirus disease 2019 (COVID-19). Conclusion: This bibliometric analysis provides a systematic overview of the VTE anticoagulation research, which will facilitate researchers to better understand the situation of VTE anticoagulation. Future studies should be dedicated to NOACs application and VTE-combined COVID-19 patients.

Transcatheter Closure of a Paravalvular Leak After Transcatheter Aortic Valve Replacement With 3-Dimensional Printing Guidance: A Case Report.

PURPOSE: Our goal was to report the transcatheter closure of a paravalvular leak after transcatheter aortic valve replacement (TAVR) using 3-dimensional (3D) printing. CASE REPORT: A 66-year-old man who had undergone transapical and TAVR 2 years ago due to aortic regurgitation, presented with palpitations and shortness of breath owing to exacerbation of paravalvular regurgitation. Echocardiography suggested that the stented aortic valve was fixed securely in place and the valve leaflets moved normally after TAVR, but there was severe paravalvular regurgitation (3 bundles, volume 11.0 mL). Due to the high surgical risk, we closed the transcatheter paravalvular leak using preprocedural guidance with 3D printing and intraprocedural guidance with digital subtraction angiography. Postoperative echocardiography showed that the paravalvular leak was significantly reduced. 3D construction showed that the occluders and the stent valve were well placed. CONCLUSION: Transcatheter closure of a paravalvular leak of the aortic valve may be feasible with appropriate pre- and intraoperative 3D printing guidance. CLINICAL IMPACT: 3D printing technology may help surgeons to make accurate preoperative strategy before occlusion procedures.

Role of Impurities in Kaolinite Intercalation and Subsequent Formation of Nanoscrolls.

Kaolinite (Kaol)-methanol (MeOH) compounds (Kaol-Me) are widely used as the starting materials for further intercalation. The conventional approach to prepare Kaol-Me compounds is to wash dimethyl sulfoxide (DMSO)-intercalated Kaol (Kaol-DMSO) for 16 days, and MeOH must be refreshed every day. Herein, we report a new and much more efficient method to prepare Kaol-Me from Kaol-DMSO by the promotion of AlCl3 under mild conditions, and the corresponding mechanism is investigated. The X-ray diffraction (XRD), Fourier transform infrared spectroscopy, and X-ray fluorescence characterization results reveal that the electric double layer resulting from the impurities absorbed on the kaolinite surface prevents weakly polar molecules from entering the kaolinite interlayers, which is probably the key reason that MeOH must be refreshed daily in the preparation of Kaol-Me compounds. After being treated with HCl to remove the impurities, Kaol-Me-HCl was successfully intercalated by cetyltrimethyl ammonium bromide and subsequently predominantly curled into nanoscrolls.

Value of the stroke 1-2-0 prehospital stroke education system: the experience of a general practitioner team.

BACKGROUND: Stroke is one of the leading causes of death worldwide, especially in developing countries. In China, there is an urgent need to educate people about stroke awareness and the importance of using emergency medical services (EMS) quickly after a stroke has occurred. OBJECTIVE: We sought to explore the effects of the Stroke 1-2-0 Prehospital Stroke Education System based on the experience of a general practitioner team. METHOD: We prospectively enrolled 119 community general practitioners to be trained in the procedures advocated by the Stroke 1-2-0 Prehospital Stroke Education System. The training content included early detection of ischemic stroke, first aid for stroke, and intravenous thrombolysis; The effects of the training were later evaluated via a before-and-after comparison. The 119 enrolled physicians formed a Stroke 1-2-0 lecturer group and taught stroke knowledge to community residents. The group remained active for 6 months, during which the medical treatment data of stroke patients (i.e., stroke onset time, prehospital delay, whether an ambulance was called, and whether thrombolytic therapy was performed) in each of 5 jurisdictions were recorded for the month before (January 2021) and that after (August 2021) the 6-month community education program. Finally, the effects of the community education program were evaluated. RESULTS: The participants' understanding of intravenous thrombolysis in the treatment of acute ischemic stroke improved significantly after the training as compared with their earlier understanding (96% vs. 78.99%; P < .001), and their understanding of the time window for intravenous thrombolysis increased from 26.05% before to 72% (P < .001) after the training. Most of the participants (90% vs. 67.23%; P < .001) said that they would immediately call the 120 emergency number of China's emergency phone system if they encountered individuals who appeared to be victims of acute stroke. A total of 82 stroke patients were seen before and 67 after the community education program. As for the use of the emergency call system, more patients with stroke activated that system after the program versus before (21.95% vs. 37.31%; P = .04). The 3-hour arrival rate after the program was nearly three times higher than that before the program (62.69% vs. 19.51%; P < .001). Also, regarding receiving thrombolysis after the occurrence of a stroke, the program triggered a substantial increase compared with the total earlier (19.4% vs. 6.1%; P = .013). CONCLUSION: We found that the Stroke 1-2-0 Prehospital Stroke Education System significantly improved community residents' knowledge regarding stroke.

Open-source environmental data as an alternative to snail surveys to assess schistosomiasis risk in areas approaching elimination.

BACKGROUND: Although the presence of intermediate snails is a necessary condition for local schistosomiasis transmission to occur, using them as surveillance targets in areas approaching elimination is challenging because the patchy and dynamic quality of snail host habitats makes collecting and testing snails labor-intensive. Meanwhile, geospatial analyses that rely on remotely sensed data are becoming popular tools for identifying environmental conditions that contribute to pathogen emergence and persistence. METHODS: In this study, we assessed whether open-source environmental data can be used to predict the presence of human Schistosoma japonicum infections among households with a similar or improved degree of accuracy compared to prediction models developed using data from comprehensive snail surveys. To do this, we used infection data collected from rural communities in Southwestern China in 2016 to develop and compare the predictive performance of two Random Forest machine learning models: one built using snail survey data, and one using open-source environmental data. RESULTS: The environmental data models outperformed the snail data models in predicting household S. japonicum infection with an estimated accuracy and Cohen's kappa value of 0.89 and 0.49, respectively, in the environmental model, compared to an accuracy and kappa of 0.86 and 0.37 for the snail model. The Normalized Difference in Water Index (an indicator of surface water presence) within half to one kilometer of the home and the distance from the home to the nearest road were among the top performing predictors in our final model. Homes were more likely to have infected residents if they were further from roads, or nearer to waterways. CONCLUSION: Our results suggest that in low-transmission environments, leveraging open-source environmental data can yield more accurate identification of pockets of human infection than using snail surveys. Furthermore, the variable importance measures from our models point to aspects of the local environment that may indicate increased risk of schistosomiasis. For example, households were more likely to have infected residents if they were further from roads or were surrounded by more surface water, highlighting areas to target in future surveillance and control efforts.

A systematic review and meta-analysis of outcomes between dusting and fragmentation in retrograde intrarenal surgery.

OBJECTIVES: Comparing stone-free rates and associated outcome measures between two surgical modalities of lithotripsy fragmentation and removal or spontaneous passage of dust during retrograde intrarenal surgery (RIRS). METHODS: In March 2023, we conducted a literature search in several widely used databases worldwide, including PubMed, Embase, and Google Scholar. We only considered English articles and excluded pediatric patients. Reviews and protocols without any published data were excluded. We also excluded articles with conference abstracts and irrelevant content. We used the Cochran-Mantel-Haenszel method and random-effects models to assess inverse variances and 95% confidence intervals (CIs) for mean differences in categorical variables. The results were reported as odds ratios (ORs) and 95% CIs. Statistical significance was set at p < 0.05. RESULTS: Our final meta-analysis included nine articles, comprising two randomized controlled trials (RCTs) and seven cohort studies. The total number of patients included in these studies was 1326, and all studies used holmium laser lithotripsy. The pooled analysis of the dust and fragmentation groups showed that the fragmentation group had a higher stone-free rate (OR 0.6; 95% CI 0.41 - 0.89; p = 0.01); the dust group had a shorter operative time (WMD - 11.6 min; 95% CI - 19.56 - -3.63; p = 0.004); and the dust group had a higher retreatment rate (OR 2.03; 95% CI 1.31 - 3.13; p = 0.001). There was no statistically significant difference between the two groups in terms of length of hospital stay, overall complications, or postoperative fever. CONCLUSIONS: Our results showed that both procedures could be safely and effectively used for upper ureteral and renal calculi lithotripsy, the dust group had potential advantages over the fragmentation group in terms of the operation time, and the fragmentation group had certain advantages in terms of stone-free rate and retreatment rate.

Perioperative, function, and positive surgical margin in extraperitoneal versus transperitoneal single port robot-assisted radical prostatectomy: a systematic review and meta-analysis.

BACKGROUND: Extraperitoneal and transperitoneal approaches are two common modalities in single-port (SP) robot-assisted radical prostatectomy (RARP), but differences in safety and efficacy between the two remain controversial. This study aimed to compare the perioperative, function, and positive surgical margin of extraperitoneal with transperitoneal approaches SP-RARP. METHODS: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement, this study is registered with PROSPERO (CRD 42023409667). We systematically searched databases including PubMed, Embase, Web of Science, and Cochrane Library to identify relevant studies published up to February 2023. Stata 15.1 software was used to analyze and calculate the risk ratio (RR) and weighted mean difference (WMD). RESULTS: A total of five studies, including 833 participants, were included in this study. The SP-TPRP group is superior to the SP-EPRP group in intraoperative blood loss (WMD: - 43.92, 95% CI - 69.81, - 18.04; p = 0.001), the incidence of postoperative Clavien-Dindo grade II and above complications (RR: 0.55, 95% CI - 0.31, 0.99; p = 0.04), and postoperative continence recovery (RR: 1.23, 95% CI 1.05, 1.45; p = 0.04). Conversely, the hospitalization stays (WMD: 7.88, 95% confidence interval: 0.65, 15.1; p = 0.03) for the SP-EPRP group was shorter than that of the SP-TPRP group. However, there was no significant difference in operation time, postoperative pain score, total incidence of postoperative complications, and positive surgical margin (PSM) rates between the two groups (p > 0.05). CONCLUSIONS: This study demonstrates that both extraperitoneal and extraperitoneal SP-RARP approaches are safe and effective. SP-TPRP is superior to SP-EPRP in postoperative blood loss, the incidence of postoperative Clavien-Dindo grade II and above complications, and postoperative continence recovery, but it is accompanied by longer hospital stays.

Application of Skin-stretching Device for Closing Scalp Defect.

BACKGROUND: The scalp defect was a clinical common constructive challenge. This research verified the efficacy of the skin-stretching device in the treatment of scalp defect and assessed the associated complications. METHODS: The clinical data of 12 patients with scalp defect treated with skin-stretching device from January 2020 to January 2021 were collected. We used EASApprox skin-stretching device for the treatment of scalp defect. We described a detailed reconstruction procedure for this treatment. We collected the site, distance from wound edge and other characteristics of the wound, and recorded the number of stretching cycles, operation time, closed state, healing time, and observed postoperative complications and wound healing status. RESULTS: In this research, the scalp defect was mainly caused by pressure ulcer, and mainly located in the parietooccipital site. The average distance from wound edge was 3.2 cm, the average stretching cycles was 4.2 times during the operation, and the average operation time was 43.5 minutes. Ten patients were directly sutured after stretching, and 2 patients underwent first-stage stretching to reduce the wound. The average time of wound healing was 13.5 days. Postoperative follow-up of 3 months, no patients had wound tear, necrosis, 1 patient suffered from wound exudation and infection due to poor nutrition. Skin function and final scar was acceptable. CONCLUSION: The treatment of skin-stretching device was effective for scalp defect and has the advantages of convenient operation, acceptable functional results, without severe complications. In addition to traditional treatment, this was a promising treatment. However, more clinical and preclinical research of the skin-stretching device were required.

The Roles of Periodontal Bacteria in Atherosclerosis.

Atherosclerosis (AS) is an inflammatory vascular disease that constitutes a major underlying cause of cardiovascular diseases (CVD) and stroke. Infection is a contributing risk factor for AS. Epidemiological evidence has implicated individuals afflicted by periodontitis displaying an increased susceptibility to AS and CVD. This review concisely outlines several prevalent periodontal pathogens identified within atherosclerotic plaques, including Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Fusobacterium nucleatum. We review the existing epidemiological evidence elucidating the association between these pathogens and AS-related diseases, and the diverse mechanisms for which these pathogens may engage in AS, such as endothelial barrier disruption, immune system activation, facilitation of monocyte adhesion and aggregation, and promotion of foam cell formation, all of which contribute to the progression and destabilization of atherosclerotic plaques. Notably, the intricate interplay among bacteria underscores the complex impact of periodontitis on AS. In conclusion, advancing our understanding of the relationship between periodontal pathogens and AS will undoubtedly offer invaluable insights and potential therapeutic avenues for the prevention and management of AS.

The effectiveness of a group-based Otago exercise program on physical function, frailty and health status in older nursing home residents: A systematic review and meta-analysis.

OBJECTIVES: To explore the effects of a group-based Otago exercise program (OEP) on physical function (mobility, balance, lower limb strength), frailty and health status in older nursing home residents to determine the optimal scheme and format. METHODS: This systematic review and meta-analysis was conducted to estimate group-based OEP effects. Subgroup analysis was performed to identify the influences of the participant and intervention characteristics on the effects. RESULTS: Twelve studies met the eligibility criteria and were included in this meta-analysis, and the overall quality was relatively high. The results showed that the group-based OEP significantly improved physical function, including mobility [SMD=-0.64, 95% CI (-0.83,-0.45), Z=6.55, p<0.001], balance [MD=4.72, 95% CI (3.54, 5.90), Z=7.84, p<0.001], lower limb strength [SMD=-1.09, 95% CI (-1.40, -0.79), Z=7.01, p<0.001]; frailty [SMD=-0.73, 95% CI (-1.01, -0.45), Z=5.13, p<0.001] and health status [SMD=0.47, 95% CI (0.20, 0.74), Z=3.44, p=0.0006]. Subgroup analysis revealed that 30-minute sessions were more beneficial for improving balance than >30-minute sessions (p=0.0004). The training was coordinated with physiotherapists, who were more skilled at improving mobility than providing health training education (p=0.04). CONCLUSIONS: Group-based OEP is helpful for improving physical function, frailty and health status in older nursing home residents. Specifically, 30-minute sessions and coordinating with physiotherapists may be the most appropriate and effective options.

Results from the China 2022 report card on physical activity for children and adolescents.

Background/Objective: Regular physical activity (PA) is beneficial to young people's health and development. In order to provide nationally representative and internationally comparable evidence on youth PA, China has participated in Global Matrix 2.0 and 3.0. The purpose of this study is to report the updated results of China's Report Card on PA for Children and Adolescents. Methods: The grades were assigned by results derived from the PA and Fitness in China--The Youth Study (PAFCTYS), conducted from October to December in 2020. The data from PAFCTYS 2020 included a nationally representative sample of Chinese school-aged children (n = 133,006, boys: 49.6%, aged 9-17 years). Self-report questionnaires were completed by the sampled students, their parents/guardians (n = 133,006), and physical education teachers (n = 1036) from each sampled school respectively. Results: The grades of China 2022 Report Card are Overall PA (C), Organized Sport Participation (F), Active Play (C-), Active Transportation (C), Sedentary behaviors (C), Physical Fitness (INC), Family and Peers (C-), School (D), Community and Environment (D-), and Government (D). Conclusion: Levels of PA among Chinese youth were low and most young people were below the recommended guidelines, although the grade of Overall PA has been improved since the modified benchmark. Prevalence of sedentary behaviors remained high. Interventions and policies at the community and environment level should be encouraged to promote PA and reduce sedentary behaviors. In addition, national policies on young people's PA should be advocated widely to ensure the policies can be transferred into action.

Predicting ultrasound-guided thermal ablation benefit in primary hyperparathyroidism.

OBJECTIVES: Ultrasound (US)-guided thermal ablation for primary hyperparathyroidism (PHPT) is a relatively novel minimally invasive treatment. The recurrence rate after ablation is between 10 and 15%. The characteristics of patients who can benefit from thermal ablation therapy are not clear yet. The aim of this research was to investigate the validity of a parathyroid hormone (PTH)-based classifier for stratifying patients with PHPT. METHODS: A total of 171 patients were screened, 148 (86.5%) of whom were eligible and were divided into development (n = 104) and external validation (n = 44) cohorts. The potential relationship between the PTH-based classifier and the cure rate of patients was initially assessed in the primary cohort and then validated in the external validation cohort. The nomogram was computed from the logistic regression model. RESULTS: A cut-off of PTH < 269.1 pg/mL or ≥ 269.1 pg/mL as the optimal prognostic threshold in the training cohort was generated to stratify the patients into low-risk and high-risk groups. Patients with PTH levels < 269.1 pg/mL in the training cohort had a higher cure rate than patients with PTH levels ≥ 269.1 pg/mL (p < 0.001). The PTH level remained the strongest predictor of the cure rate in all cohorts. Furthermore, a nomogram based on the PTH level was developed to predict the cure rate in the training cohort and it performed well in the external validation cohort (AUC: 0.816, 95%CI 0.703 to 0.930; AUC: 0.816, 95%CI 0.677 to 0.956). CONCLUSIONS: The PTH-based classifier may help with individualised treatment planning for selecting patients who may benefit from thermal ablation. KEY POINTS: • This is the first analysis of predictors affecting the outcome of US-guided thermal ablation of primary hyperparathyroidism and the findings can be used to identify the potential beneficiary population of thermal ablation of primary hyperparathyroidism. • Parathyroid hormone (PTH) was confirmed as an independent prognostic factor, as it not only showed good accuracy in stratifying patients into high- and low-risk groups in the training and validation cohorts but also outperformed the clinical model. • This study developed and validated a model to predict the treatment success of thermal ablation of primary hyperparathyroidism.

No Benefit of Wearing Compression Stockings after Endovenous Thermal Ablation of Varicose Veins: A Systematic Review and Meta-Analysis.

OBJECTIVE: This meta-analysis was conducted to investigate whether compression stockings were necessary after endovenous thermal ablation of varicose veins. DATA SOURCES: Electronic databases, including MEDLINE, EMBASE, and the Cochrane Library database, were searched from inception to 10 March 2021 to identify all the related trials. METHODS: Random or fixed effects models were used to generate pooled mean difference (MD) or standardised mean difference (SMD) for continuous data, risk ratios (RRs) for dichotomous data, and related 95% confidence intervals (95% CIs). The quality of evidence was graded with a specific tool (GRADEpro GDT) from the GRADE working group. RESULTS: A total of seven randomised controlled trials (RCTs) comprising 1 146 patients were included in this meta-analysis. Wearing compression stockings was correlated with lower post-operative pain scores from a 0 to 100 mm visual analogue scale (MD -8.00; 95% CI -12.01 - -3.99; p < .001). No difference was observed between wearing compression stockings or not in quality of life (SMD 0.45; 95% CI 0.14 - 1.04), major complications (RR 0.64; 95% CI 0.26 -1.59), target vein occlusion rates (RR 0.99; 95% CI 0.96 - 1.02), or time to return to work (MD -0.43; 95% CI 1.06 - 0.19). CONCLUSION: After endovenous thermal ablation of varicose veins, wearing compression stockings was not associated with a better outcome except for mild pain relief. Post-operative compression stockings may be unnecessary after endovenous thermal ablation.

The efficacy and safety of topical Tretinoin combined with superficial X-ray therapy (SXRT) in treating periungual warts.

There are multiple treatment modalities for periungual warts (PWs), although most are destructive and painful, limiting their application. Radiotherapy is a non-invasive method suitable for treating PW patients with contraindications to invasive procedures. To investigate the efficacy and safety of topical Tretinoin combined with Superficial X-ray therapy (SXRT) in treating PWs. This study included patients with 65 PWs who underwent treatment and a 3-month follow-up. Twenty four PWs were subjected to SXRT alone (group A). The remaining 41 PWs were subjected to SXRT combined with the application of the Tretinoin cream from the first day (group B). The overall clinical response rate, recurrence rates, cosmetic outcomes, and adverse events were observed during the follow-up period. The complete clearance rate (75% vs. 92.7% in groups A and B, respectively) and healing times (19.9 vs. 16.0 days in groups A and B, respectively) between the two groups were significantly different (p < 0.046 and 0.04), indicating the combination treatment is more effective. Notably, there was no damaging or permanent deformation on the nail, and the other adverse effects were mild and bearable. Topical Tretinoin combined with SXRT therapy is an effective strategy for treating PWs, with minor side effects. It is painless and with excellent cosmetic outcomes.
