Review
The popularity of surfing has increased exponentially, reaching its recent debut in the Olympic Games. However, surfing suffers from a relative immature technological market, while in other sports some technologies such as global navigation satellite systems (GNSSs) have become an essential work material for strength and conditioning and head coaches. This article aims to systematically review surfers' time-motion demands based on GNSSs. A systematic review of relevant articles was carried out using five main databases (PubMed, ProQuest Central, SCOPUS, SPORTDiscus, and FECYT (Web of Sciences, CCC, CIDW, KJD, MEDLINE, RSCI, and SCIELO)) until 23 March 2024. From the 238 studies initially found, 9 were included in the qualitative synthesis. In these, GNSS devices were employed with male (n = 143) and female (n = 28) surfers from different levels during competition and training situations. The studies show that the intermittent nature of the sport is evident, with substantial periods spent paddling and waiting punctuated by relatively brief high-intensity efforts when riding waves at high speeds. Notable differences emerged between competition and training demands, suggesting potential mismatches in how athletes currently prepare compared to event requirements. These novel insights allow quantifying surfing's harsh physiological requirements and could guide conditioning practices to better meet the sport's unique characteristics across populations. Therefore, training should emulate the lengthy aerobic capabilities needed for the paddling volumes observed, while also targeting the anaerobic systems to meet the repeated high-intensity surf riding efforts. However, inconsistencies in methods and reporting practices limit direct comparisons and comprehensive profiling of the sport's physical characteristics.

Review
Large language models (LLMs) represent a recent advancement in artificial intelligence with medical applications across various healthcare domains. The objective of this review is to highlight how LLMs can be utilized by clinicians and surgeons in their everyday practice. A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Six databases were searched to identify relevant articles. Eligibility criteria emphasized articles focused primarily on clinical and surgical applications of LLMs. The literature search yielded 333 results, with 34 meeting eligibility criteria. All articles were from 2023. There were 14 original research articles, four letters, one interview, and 15 review articles. These articles covered a wide variety of medical specialties, including various surgical subspecialties. : LLMs have the potential to enhance healthcare delivery. In clinical settings, LLMs can assist in diagnosis, treatment guidance, patient triage, physician knowledge augmentation, and administrative tasks. In surgical settings, LLMs can assist surgeons with documentation, surgical planning, and intraoperative guidance. However, addressing their limitations and concerns, particularly those related to accuracy and biases, is crucial. LLMs should be viewed as tools to complement, not replace, the expertise of healthcare professionals.

Review
Temporomandibular disorders (TMDs) are a heterogeneous group of musculoskeletal and neuromuscular conditions involving the temporomandibular joint (TMJ), masticatory muscles, and associated structures. Mesenchymal stromal/stem cells (MSCs) have emerged as a promising therapy for TMJ repair. This systematic review aims to consolidate findings from the preclinical animal studies evaluating MSC-based therapies, including MSCs, their secretome, and extracellular vesicles (EVs), for the treatment of TMJ cartilage/osteochondral defects and osteoarthritis (OA). Following the PRISMA guidelines, PubMed, Embase, Scopus, and Cochrane Library databases were searched for relevant studies. A total of 23 studies involving 125 , 149 , 470 , and 74 were identified. Compliance with the ARRIVE guidelines was evaluated for quality assessment, while the SYRCLE risk of bias tool was used to assess the risk of bias for the studies. Generally, MSC-based therapies demonstrated efficacy in TMJ repair across animal models of TMJ defects and OA. In most studies, animals treated with MSCs, their derived secretome, or EVs displayed improved morphological, histological, molecular, and behavioral pain outcomes, coupled with positive effects on cellular proliferation, migration, and matrix synthesis, as well as immunomodulation. However, unclear risk in bias and incomplete reporting highlight the need for standardized outcome measurements and reporting in future investigations.

BACKGROUND
Different factors can affect the quality of life of patients treated for head and neck cancer undergoing major surgical intervention. However, it remains unclear which specific factors and what possible interventions could have the greatest influence on quality of life postoperatively for patients undergoing surgical resection with free flap reconstruction. The objective of our systematic review was to identify which factors, at the time of surgical treatment, are associated with a worse postoperative quality of life for patients undergoing surgical resection with free flap reconstruction for head and neck cancer.
METHODS
We performed a systematic review of MEDLINE, Embase, CINAHL, Web of Science, and the Cochrane Central Register of Controlled Trials (CENTRAL), from their inception through November 2021. We included peer reviewed studies that evaluated the impact of specific factors on quality of life for adult patients who underwent surgery with free flap reconstruction for head and neck cancer. Two reviewers independently screened citations for eligibility and extracted data. Risk of bias of each study was evaluated using the New-Castle Ottawa Scale. Vote counting and qualitative review were used to synthesize results. All relevant findings were reported.
RESULTS
We initially identified 1971 articles. We included 22 articles in our systematic review, totaling 1398 patients. There was a high level of variability for factors evaluated throughout studies and many studies presented small sample sizes. However, some factors were associated with worse long-term quality of life, including older age, radiotherapy, higher tumor stage, dysphagia, anxiety as well as depressive symptoms. Very few articles analyzed their data for specific tumor subsites and the impact of psychosocial factors was rarely evaluated throughout studies.
CONCLUSIONS
For patients with head and neck cancer requiring free flap reconstruction, some specific factors may correlate with changes in quality of life. However, these findings are based on very few and mostly underpowered studies. A better understanding of factors affecting quality of life could allow a more personalized and overall better quality of care for patients.

Review
PURPOSE
Our aim was to update evidence-based and consensus-based recommendations for the surgical and interventional management of blunt or penetrating injuries to the chest in patients with multiple and/or severe injuries on the basis of current evidence. This guideline topic is part of the 2022 update of the German Guideline on the Treatment of Patients with Multiple and/or Severe Injuries.
METHODS
MEDLINE and Embase were systematically searched to May and June 2021 respectively for the update and new questions. Further literature reports were obtained from clinical experts. Randomised controlled trials, prospective cohort studies, cross-sectional studies and comparative registry studies were included if they compared interventions for the surgical management of injuries to the chest in patients with multiple and/or severe injuries. We considered patient-relevant clinical outcomes such as mortality, length of stay, and diagnostic test accuracy. Risk of bias was assessed using NICE 2012 checklists. The evidence was synthesised narratively, and expert consensus was used to develop recommendations and determine their strength.
RESULTS
One study was identified. This study compared wedge resection, lobectomy and pneumonectomy in the management of patients with severe chest trauma that required some form of lung resection. Based on the updated evidence and expert consensus, one recommendation was modified and two additional good practice points were developed. All achieved strong consensus. The recommendation on the amount of blood loss that is used as an indication for surgical intervention in patients with chest injuries was modified to reflect new findings in trauma care and patient stabilisation. The new good clinical practice points (GPPs) on the use of video-assisted thoracoscopic surgery (VATS) in patients with initial circulatory stability are also in line with current practice in patient care.
CONCLUSION
As has been shown in recent decades, the treatment of chest trauma has become less and less invasive for the patient as diagnostic and technical possibilities have expanded. Examples include interventional stenting of aortic injuries, video-assisted thoracoscopy and parenchyma-sparing treatment of lung injuries. These less invasive treatment concepts reduce morbidity and mortality in the primary surgical phase following a chest trauma.

Meta-Analysis Review
BACKGROUND
The scapular free flap (SFF) is essential in complex reconstructive surgery and often indicated in complex defects with compromised or poor local tissue integrity. This review aims to assess the versatility and reliability of the SFF during reconstruction.
METHODS
A comprehensive literature review of multiple databases was conducted following the PRISMA guidelines. An analysis of pooled data was performed to evaluate flap failure rate for any anatomical unit using SFF as the primary endpoints. Secondary endpoints included other complication rates after reconstruction such as partial flap loss, revision surgery, fistula, hematoma, and infection.
RESULTS
A total of 110 articles were included, with 1447 pooled flaps. The main recipient site was the head and neck region (89.0%). Major indications for reconstruction were malignancy (55.3%), burns (19.2%), and trauma (9.3%). The most common types of flaps were osteocutaneous (23.3%), cutaneous (22.6%), and chimeric (18.0%). The pooled flap failure rate was 2% (95%CI: 1%-4%). No significant heterogeneity was present across studies (Q statistic 20.2, p = .69; I .00%, p = .685). Nonscapular supplementary flaps and grafts were required in 61 cases. The average length and surface area of bone flaps were 7.2 cm and 24.8cm, respectively. The average skin paddle area was 134.2cm.
CONCLUSION
The SFF is a useful adjunct in the reconstructive surgeon's armamentarium as evidence by its intrinsic versatility and diverse clinical indications. Our data suggest a low failure rate in multicomponent defect reconstruction, especially in head and neck surgery. SFFs enable incorporation of multiple tissue types and customizable dimensions-both for vascularized bone and cutaneous skin-augmenting its value in the microsurgeon's repertoire as a chimeric flap. Further research is necessary to overcome the conventional barriers to SFF utilization and to better comprehend the specific scenarios in which the SFF can serve as the preferred alternative workhorse flap.

BACKGROUND
The use of post-mastectomy radiation therapy (PMRT) in the setting of immediate two-stage breast reconstruction is becoming increasingly widespread. However, the timeframe of tissue expander exchange for permanent implant placement following PMRT is not well-defined, and it remains unclear what time interval optimizes surgical outcomes and patient satisfaction.
METHODS
A systematic review conducted in accordance with PRISMA 2020 was completed. PubMed, Embase, Scopus, and Cochrane databases were searched under keywords pertaining to concepts of tissue expander breast reconstruction and PMRT. Inclusion criteria encompassed primary articles on tissue expander breast reconstruction with adjuvant radiation therapy reporting timing of exchange to permanent implant following radiation and surgical outcomes.
RESULTS
Of the initial 1,259 publications, 15 studies met our inclusion criteria, and 11 studies had granular enough data to use for pooled analysis. Implant exchange less than 6 months after PMRT was found to be associated with increased incidence of wound dehiscence (17.12% vs 3.64%, p<0.001) and hematoma (25% vs 2.59%, p<0.001) compared to exchange after 6 months. There was no significant difference in incidence of SSI, seroma, capsular contracture, and reconstructive failure.
CONCLUSIONS
Expander to implant exchange at less than 6 months is associated with a higher incidence of wound dehiscence and hematoma formation but does not increase the risk of reconstruction failure. The limited research on ideal timing prompts further investigation to optimize surgical outcomes for the increasing patient population undergoing PMRT and immediate two-staged breast reconstruction.

Meta-Analysis Comparative Study
BACKGROUND
Vascularized lymph node transfer (VLNT) involves the microvascular transplantation of functional lymph nodes from a donor site into a limb affected by lymphedema to restore the normal flow of lymphatic fluid. Despite the increasing clinical experience with VLNT, there remains insufficient data to support its routine use in clinical practice. Here, we aim to evaluate the effectiveness and safety of VLNTs for upper limb lymphedema and compare clinical outcomes when using different donor sites.
METHODS
We carried out a systematic search of the literature through PubMed and Scopus databases for studies on VLNT for upper limb lymphedema. Primary and secondary outcomes included circumference reduction rate (CRR) and infection reduction rate by postoperative cellulitis episodes for the efficacy and safety of VLNT. Pooled analysis was performed using the inverse variance weighting meta-analysis of single means using the meta package in R software. Subgroup analyses were performed for donor and recipient sites, age groups, follow-ups, and symptom durations. Quality assessment was performed using the Newcastle-Ottawa Scale for nonrandomized studies.
RESULTS
A total of 1089 studies were retrieved from the literature, and 15 studies with 448 upper limb lymphedema patients who underwent VLNT were included after eligibility assessment. The mean CRR was 34.6 (18.8) and the mean postoperative cellulitis episodes per year was 0.71 (0.7). The pooled analysis of CRR was 28.4% (95% confidence interval, 19.7-41.1) and postoperative cellulitis episodes showed a mean of 0.59 (95% confidence interval, 0.36-0.95) using the random-effect model. Subgroup analyses showed significant group differences in recipient site for CRR and postoperative cellulitis episodes with the wrist comprising the highest weights, and patients younger than 50 years showing a lower postoperative infection.
CONCLUSIONS
Vascularized lymph node transfer using gastroepiploic flaps at the wrists has shown a significant difference in reductions of limb circumference and cellulitis episodes in upper limb lymphedema patients when compared with other donor sites. However, further prospective studies are needed to consolidate this finding.

BACKGROUND
Raynaud disease of the hands is a complex disorder resulting in inappropriate constriction and/or insufficient dilation in microcirculation. There is an emerging role for botulinum toxin type A (BTX-A) in the treatment armamentarium for refractory Raynaud disease. The aim of this systematic review was to critically evaluate the management of primary and secondary Raynaud disease treated with BTX-A intervention.
METHODS
We performed a Preferred Reporting Items for Systematic Reviews and Meta-Analyses-compliant systematic review of clinical studies assessing treatment of primary or secondary Raynaud disease with BTX-A by searching Ovid MEDLINE and Embase databases from inception to first August 2023. The review protocol was prospectively registered on the PROSPERO database (CRD42022312253).
RESULTS
Our search strategy identified 288 research articles, of which 18 studies [four randomized controlled trials (RCTs), two non-RCTs, five case series, and seven retrospective cohort studies] were eligible for analysis. Meta-analysis demonstrated that the probability of pain visual analog scale score improvement with BTX-A intervention was 81.95% [95% confidence interval (74.12-87.81) = 0.19, heterogeneity = 26%] and probability of digital ulcer healing was 79.37% [95% confidence interval (62.45-89.9) = 0.02, heterogeneity = 56%].
CONCLUSIONS
Delivery of BTX-A to digital vessels in the hand may be an effective management strategy for primary and secondary Raynaud disease. A definitive, appropriately-powered RCT with objective functional and patient-reported outcome measures is required to accurately assess and quantify the efficacy of BTX-A in Raynaud disease of the hands.

Annals of Surgery Jun 2024This study evaluated the efficacy of various local management strategies for diabetic foot ulcers (DFUs).
OBJECTIVE
This study evaluated the efficacy of various local management strategies for diabetic foot ulcers (DFUs).
BACKGROUND
Several surgical and non-surgical local interventional approaches are available for the treatment of DFUs. The comparative effectiveness of different treatments is unknown, and it remains unclear which approach is the optimal choice for DFUs treatment due to limited direct comparisons.
METHODS
We did a systematic review and meta-analysis to select the optimal approach to DFUs local management. We searched Medline, Embase, Web of Science, and ClinicalTrials.gov from inception to September 1, 2023, to identify relevant randomized controlled trials (RCTs). We analysed data by pairwise meta-analyses with a random-effects model. A network meta-analysis using the surface under the cumulative ranking curve (SUCRA) was performed to evaluate the comparative efficacy of different interventional approaches in the early (within 12 wk) and late stages (over 12 wk).
RESULTS
141 RCTs involving 14076 patients and exploring 14 interventional strategies were eligible for inclusion. Most studies (102/141) had at least one risk-of-bias dimension. Good consistency was observed during the analysis. Local pairwise comparisons demonstrated obvious differences in the early-stage healing rate and early- and late-stage healing times, while no significant difference in the late-stage healing rate or adverse events were noted. SUCRAs identified the standard of care (SOC) + decellularized dressing (DD), off-loading (OL), and autogenous graft (AG) as the three most effective interventions within 12 weeks for both healing rate (97%, mean rank: 1.4; 90%, mean rank: 2.3; 80.8%, mean rank: 3.5, respectively) and healing time (96.7%, mean rank: 1.4; 83.0%, mean rank: 3.0; 76.8%, mean rank: 3.8, respectively). After 12 weeks, local drug therapy (LDT) (89.5%, mean rank: 2.4) and OL (82.4%, mean rank: 3.3) ranked the highest for healing rate, and OL (100.0%, mean rank: 1.0) for healing time. With respect to adverse events, moderate and high risks were detected in the SOC + DD (53.7%, mean rank: 7.0) and OL (24.4%, mean rank: 10.8) groups, respectively.
CONCLUSION
The findings suggest that OL provided considerable benefits for DFU healing in both the early and late stages, but the high risk of adverse events warrants caution. SOC+DD may be the preferred option in the early stages, with an acceptable risk of adverse events.
