Genetic and Epigenetic Association of FOXP3 with Papillary Thyroid Cancer Predisposition.

Papillary thyroid cancer (PTC) is the most common type of thyroid malignancy with an increased female incidence ratio. The specific traits of X chromosome inheritance may be implicated in gender differences of PTC predisposition. The aim of this study was to investigate the association of two X-linked genes, Forkhead Box P3 (FOXP3) and Protein Phosphatase 1 Regulatory Subunit 3F (PPP1R3F), with PTC predisposition and gender disparity. One hundred thirty-six patients with PTC and an equal number of matched healthy volunteers were enrolled in the study. Genotyping for rs3761548 (FOXP3) and rs5953283 (PPP1R3F) was performed using polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP). The methylation status of FOXP3 was assessed using the combined bisulfite restriction analysis (COBRA) method. The SPSS software was used for statistical analyses. Gender stratification analysis revealed that the CA and AA genotypes and the A allele of FOXP3 rs3761548 variant are associated with PTC predisposition only in females. Moreover, different methylation status was observed up to the promoter locus of FOXP3 between PTC female patients, carrying the CA and CC genotype, and controls. Both revealed associations may explain the higher PTC incidence in females through reducing FOXP3 expression as reported in immune related blood cells.

Thyroid cancer and pregnancy: a systematic ten-year-review.

Background: Thyroid cancer is the second most common malignancy during pregnancy, especially the well-differentiated thyroid cancer (well-DTC). Therefore, complex medical and social dilemmas arise, dealing with which requires deep knowledge of the nature and characteristics of the disease and pregnancy as a whole. The purpose of this review is to present the diagnostic and therapeutic strategies of thyroid cancer during pregnancy and the postpartum period. Methods: Extended review of the literature [2011-2023] was performed. Two hundred ninety-six articles were found, from which 225 were excluded due to irrelevant subjects. Seventy-one articles were assessed for eligibility, from which 33 articles were cohort studies and case reports and were included in the review. Results: From the 33 included studies, 18 were retrospective cohort studies, 1 was cohort study, 2 were case control studies, 1 was meta-analysis and 11 were case reports. The primary endpoints of these studies refer to the progression and recurrence of DTC during pregnancy, the prevalence of thyroid cancer in pregnancy and the most appropriate time for surgical intervention. Conclusions: The majority of the studies agree that well-differentiated tumors with mild clinical and imaging characteristics do not require immediate surgical treatment, but mere monitoring. Surgery can be delayed after childbirth. In contrast, tumors with aggressive behavior as well as non-differentiated ones, require immediate surgery because delay under these circumstances can dramatically reduce survival rates. Finally, a history of thyroid cancer does not seem to affect future deliveries, on condition that no residual disease exists at the onset of pregnancy.

Endovenous laser ablation (EVLA) 980 nm versus 1470 nm and the impact of fiber type: a systematic review and meta-analysis.

We sought to assess the efficacy and safety of endovenous laser ablation utilizing a 980 nm device versus a 1470 nm device in the treatment of lower limb venous insufficiency. We performed a systematic review adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement. A research on PubMed, Scopus and Web of science for articles published by January 2024 was conducted. The primary endpoint was great saphenous vein (GSV) and truncal vein occlusion. Eleven studies encompassing 3061 patients and 3193 truncal veins, were included. The 1470 nm device demonstrated superior truncal vein and GSV occlusion outcomes compared to the 980 nm device at the early, one-year, and medium to long-term follow-up intervals. Odds ratios (OR) were 2.79(95%CI:1.31-5.94), 2.22(95%CI:1.21-4.07), and 2.02(95%CI:1.24-3.29) for truncal veins and 2.54(95%CI:1.119-5.41), 2.06(95%CI:1.07-3.95) and 2.04(95%CI:1.25-3.33) for GSV, across the respective intervals. While both devices demonstrated minimal, deep vein thrombosis (DVT), endovenous heat-induced thrombosis (EHIT) ≥ 2, and burn estimates, the 1470 nm device exhibited improved paresthesia, risk ratio (RR), 0.51(95%CI:0.34-0.77) and pain outcomes, standardized mean difference (SMD), -0.62(95%CI:-0.99to-0.25). Subgroup analysis displayed enhanced occlusion outcomes with the 1470 nm device for the six-month and one-year intervals, irrespective of fiber type. Radial fibers were associated with improved paresthesia outcomes (ß=-0.9520,p = 0.03). This review emphasized the enhanced efficacy of the 1470 nm device over the 980 nm device, regardless of fiber type. Radial fibers showed promise for improved paresthesia outcomes, suggesting similar safety profiles for both systems. Conclusive remarks on pain outcomes were impeded by data limitations.

Thyroidectomy in children and adolescents: a systematic review.

Background: Thyroid surgery in pediatric population is not as common as that in adults, although they share the same indications, techniques and complications. This review aims to evaluate the surgical management of thyroid disease in patients under 18 years old. Methods: We conducted a bibliographic search in the international literature. Data from the identified studies such as demographics, indication for surgery, type of procedure, complications and length of hospital stay were recorded. A retrospective review study of all patients under 18 years old who underwent thyroidectomy was performed. Results: We included 37 retrospective studies and a total of 12,728 patients. Thyroidectomy was more common in female patients and the mean age was approximately 14 years old. The leading indication for surgery was benign thyroid pathology. Due to the surgical treatments' safety and effectiveness in young patients, total and subtotal thyroidectomy, whether for malignancies or benign diseases, is becoming more popular today. The most often occurring complication of pediatric thyroid surgery is hypoparathyroidism. Despite the high likelihood of recurrence of pediatric malignancies, overall survival rates of pediatric thyroid cancer are excellent. Conclusions: Thyroidectomy performed by high-volume thyroid surgeons in children and adolescents is considered an efficient and safe method of treatment of thyroid disease.

Sequential Graft Limb Occlusion Following Endovascular Aneurysm Repair: A Case Report and Literature Review.

Limb graft occlusion (LGO) is a common complication that can occur after endovascular aneurysm repair (EVAR). There are many factors that can contribute to LGO, including patient-related variables, device-related considerations, and factors associated with the procedural technique. Patients with LGO may exhibit no symptoms, have intermittent claudication, or suffer from acute limb ischemia. In this manuscript, we present a case of a 64-year-old male who experienced sequential LGOs after EVAR accompanied by a comprehensive review of the pertinent literature.

Diagnostic Accuracy of Ultrasound and Fine-Needle Aspiration Cytology in Thyroid Malignancy.

Introduction: Thyroid nodule incidence is increasing due to the widespread application of ultrasonography. Fine-needle aspiration cytology is widely applied for the detection of malignancies. The aim of this study was to evaluate the predictive value of ultrasonography in thyroid cancer. Methods: This retrospective study included patients that underwent total thyroidectomy for benign thyroid disease or well-differentiated thyroid carcinoma from January 2017 to December 2022. The study population was divided into groups: the well-differentiated thyroid cancer group and the control group with benign histopathological reports. Results: In total, 192 patients were enrolled in our study; 159 patients were included in the well-differentiated thyroid cancer group and 33 patients in the control group. Statistical analysis demonstrated that ultrasonographic findings such as microcalcifications (90.4%), hypoechogenicity (89.3%), irregular margins (92.2%) and taller-than-wide shape (90.5%) were correlated to malignancy (p < 0.001). Uni- and multivariate analysis revealed that both US score (OR: 2.177; p < 0.001) and Bethesda System (OR: 1.875; p = 0.002) could predict malignancies. In terms of diagnostic accuracy, the US score displayed higher sensitivity (64.2% vs. 33.3%) and better negative predictive value (34.5% vs. 24.4%) than the Bethesda score, while both scoring systems displayed comparable specificities (90.9% vs. 100%) and positive predictive values (97.1% vs. 100%). Discussion: The malignant potential of thyroid nodules is a crucial subject, leading the decision for surgery. Ultrasonography and fine-needle aspiration cytology are pivotal examinations in the diagnostic process, with ultrasonography demonstrating better negative predictive value.

The Effect of Probiotics on the Prognostication of the Neutrophil-to-Lymphocyte Ratio in Severe Multi-Trauma Patients.

BACKGROUND: The ratio of neutrophils to lymphocytes [NLR] is one of the most accepted prognostic indices and demonstrates a positive correlation with the severity of a disease. Given that probiotics exerted immunomodulatory properties and thus positively affected lymphocytopenia induction in severely ill patients, we performed a post hoc analysis in the ProVAP protocol to investigate whether probiotics affected the prognostication of NLR in respect to ventilator-associated pneumonia in multi-trauma patients. This cohort mandatorily involved severe traumatic brain injury patients. METHODS: The white blood cell data of all patients, after being retrieved for the days 0 and 7, were statistically assessed in respect to neutrophils, lymphocytes and NLR among the 4 sub-groups of the study: placebo/no-VAP, placebo/VAP, probiotics/no-VAP, and probiotics/VAP. RESULTS: Lymphopenia was dominant in placebo sub-groups, while an increased level of lymphocytes was prominent in probiotics sub-groups. This resulted in an increase [p = 0.018] in the NLR value in the probiotics/VAP group in relation to the probiotics/no-VAP cohort; this was an increase of half the value of the placebo/VAP [p < 0.001], while the NLR value in placebo/no-VAP group increased almost four-fold in relation to probiotics/no-VAP [p < 0.001]. Additionally, the ROC curve for probiotic-treated patients revealed a NLR7 cut-off value of 7.20 as a prognostic factor of VAP (AUC: 78.6%, p = 0.015, 95% CI: 62.6-94.5%), having a high specificity of 90.2% and a sensitivity of 42.9%. CONCLUSIONS: NLR may considered a credible prognostic biomarker in multi-trauma patients since it can evaluate the immunomodulatory benefits of probiotic treatment. However, the results of the present post hoc analysis should be interpreted meticulously until further evaluation, since they may be basically species- or strain-specific.

Long-Term Outcomes of Anatomical and Extra-Anatomical Bypass for the Treatment of Unilateral Iliac Artery Lesions a Systematic Review Aggregated Data and Individual Participant Data Meta-Analysis.

BACKGROUND: We investigated the long-term safety and efficacy of anatomical and extra-anatomical bypass for the treatment of unilateral iliac artery disease. METHODS: A systematic search on PubMed, Scopus and Web of science for articles published by June 2023 was performed. We implemented a 2-stage individual participant data meta-analysis and pooled survival probabilities using the multivariate methodology of DerSimonian and Laird. The primary endpoint was primary patency at 5 and 10 years of follow-up. RESULTS: Ten studies encompassing 1,907 patients were included. The 5- and 10-year pooled patency rates for anatomical bypass were 83.27% (95% confidence interval (CI): 69.99-99.07) and 77.30% (95% CI: 60.32-99.04), respectively, with a mean primary patency time representing the duration individuals remained event-free for 10.08 years (95% CI: 8.05-10.97). The 5- and 10-year pooled primary patency estimates for extra-anatomical bypass were 77.02% (95% CI: 66.79-88.80) and 68.54% (95% CI: 53.32-88.09), respectively, with a mean primary patency time of 9.25 years, (95% CI: 7.21-9.68). Upon 2-stage individual participant data meta-analysis, anatomical bypass displayed a decreased risk for loss of primary patency compared to extra-anatomical bypass, hazard ratio 0.51 (95% CI: 0.30-0.85). The 5- and 10-year secondary patency estimates for anatomical bypass were 96.83% (95% CI: 90.28-100) and 96.13% (95% CI: 88.72-100), respectively. The 5- and 10-year secondary patency estimates for extra-anatomical bypass were 91.39% (95% CI: 84.32-99.04) and 85.05% (95% CI: 74.43-97.18), respectively, with non-statistically significant difference between the 2 groups. The 5- and 10-year survival for patients undergoing anatomical bypass were 67.99% (95% CI: 53.84-85.85) and 41.09% (95% CI: 25.36-66.57), respectively. The 5- and 10-year survival for extra-anatomical bypass were 70.67% (95% CI: 56.76-87.98) and 34.85% (95% CI: 19.76-61.44), respectively. The mean survival time was 6.92 years (95% CI: 5.56-7.89) for the anatomical and 6.78 years (95% CI: 5.31-7.63) for the extra-anatomical groups. The pooled overall 30-day mortality was 2.32% (95% CI: 1.12-3.87) with metaregression analysis displaying a negative association between the year of publication and mortality (ß =-0.0065, P < 0.01). Further analysis displayed a 30-day mortality of 1.29% (95% CI: 0.56-2.26) versus 4.02% (95% CI: 1.78-7.03), (P = 0.02) for studies published after and before the year 2000. Non-statistically significant differences were identified between the 2 groups concerning long-term and 30-day mortality outcomes. CONCLUSIONS: While we have demonstrated favorable long-term primary and secondary patency outcomes for both surgical techniques, anatomical bypass exhibited a reduced risk of primary patency loss potentially reflecting its inherent capacity to circumvent the anticipated disease progression in the distal aorta and the contralateral donor artery. The reduction in perioperative mortality observed in our review, coupled with the anachronistic demographic characteristics and inclusion criteria presented in the existing literature, underscores the imperative necessity for contemporary research.

Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy for hemorrhoidal disease: a systematic review and meta-analysis.

BACKGROUND: We conducted a systematic review to assess the safety and efficacy of Aluminum potassium sulfate and tannic acid (ALTA) sclerotherapy for the treatment of hemorrhoidal disease. METHODS: Our study was conducted in accordance with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-analyses) 2020. Primary endpoints included overall recurrence and type of recurrence while secondary endpoints included postoperative complications, reintervention, presence of rectal ulcer, rectal stricture, defecation abnormalities and perianal abscess. Α regression analysis, where the percentage of patients with grade II, III and IV hemorrhoidal disease was used as a covariate, was also performed. RESULTS: Twelve studies with 4249 patients met all the inclusion criteria and were eventually included. The crude and pooled estimates of the overall recurrence and complications by the end of follow-up were 10% (95% CI, 6.52%-14.08%) and 5.20% (95% CI, 2.59%-8.52%), respectively. Regression analysis displayed no correlation between recurrence and the grade of hemorrhoid disease II, ß= -0.0012 (95% CI, -0.0074 to 0.0049) (p = .64), grade III ß= -0.0006 (95% CI, -0.0056 to 0.0045) (p = .79) and grade IV ß = 0.0025 (95% CI, -0.0075 to 0.0124). However, a trend suggestive of increased recurrence was observed in patient populations with a higher proportion of grade IV disease. CONCLUSION: ALTA sclerotherapy may be a safe and viable alternative for patients with hemorrhoidal disease. Long-term follow-up and high-quality randomized controlled trials will help define the place of ALTA sclerotherapy in the armamentarium of treatment of hemorrhoids.

A systematic review meta-analysis and meta-regression on the implications of an aberrant right hepatic artery in patients undergoing pancreaticoduodenectomy for the treatment of malignant disease.

We investigated the outcomes of pancreaticoduodenectomy in the presence of an aberrant right hepatic artery (aRHA). We systematically reviewed Medline, Scopus, and Web of Science until April 2023 for studies comparing pancreaticoduodenectomy outcomes with and without aRHA. Endpoints included postoperative mortality, R0 resection margins, pancreatic fistulae, hemorrhage, biliary leak/fistulae, delayed gastric emptying, operative duration, and blood loss. Eight retrospective studies involving 1514 patients were included. The risk ratio (RR) for postoperative mortality and odds ratio (OR) for R0 resection between the aRHA and normal anatomy groups were 1.37 (95%CI:0.74-256) (I2=0%, P=0.99) and 1.03 (95%CI:0.67-1.59) (I2=10%, P=0.35). Besides a longer operative duration in the aRHA group, mean difference (MD) 54.64 (95% CI: 8.51-100.77) (I2=94%, P<0.01), there were no significant differences in secondary endpoints. Meta-regression revealed a significant association between aRHA reconstruction and postoperative mortality (ß=0.0179, P<0.01). This review displayed non-statistically significant differences in terms of surgical and oncological outcomes between patients with aRHA and patients with normal hepatic artery anatomy undergoing pancreaticoduodenectomy. However, the observed trend of increased postoperative mortality in patients with aRHA, combined with extended surgical duration and the link between aRHA reconstruction and postoperative mortality, prevents drawing definitive conclusions. Further research through high-quality studies is warranted.

Probiotics in Postoperative Pain Management.

Postoperative pain is the unpleasant sensory and emotional experience after surgery, its origin being both the inflammatory reaction induced by the surgical trauma on the abdominal wall and the splanchnic pain induced by the activation of nociceptors of the viscera, which are highly sensitive to distension, ischemia, and inflammation. Nowadays, it is well recognized that there is a close relationship between the gut microbiome and pain perception, and that microbiome is highly affected by both anesthesia and surgical manipulation. Thus, efforts to restore the disturbed microbiome via supplementation with beneficial bacteria, namely probiotics, seem to be effective. In this article, the knowledge gained mainly from experimental research on this topic is analyzed, the concluding message being that each probiotic strain works in its own way towards pain relief.

A Systematic Review Network Meta-Analysis and Meta-Regression on Surgical and Endovenous Interventions for the Treatment of Lower Limb Venous Ulcer Disease.

BACKGROUND: Venous leg ulcer (VLU) disease constitutes the most severe form of chronic venous insufficiency. We performed a network meta-analysis and meta-regression to investigate the efficacy and safety of the various available interventions in the treatment of VLU. METHODS: We conducted a systematic research corresponding to the instructions by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement for studies reporting on surgical or endovenous interventions for the treatment of VLU. Following data extraction, we performed a Bayesian network meta-analysis and meta-regression. Primary endpoints included VLU healing and recurrence. The secondary endpoint was postintervention complications. RESULTS: Seventeen studies evaluating the impact of compression monotherapy, radiofrequency ablation (RFA), endovenous laser ablation (EVLA), sclerotherapy, and saphenous vein surgery on VLU treatment, consisting of 2156 patients (2186 VLU) were included. When compared to compression monotherapy, RFA was the only treatment displaying a statistically-significant impact on ulcer healing, odds ratio (OR) 5.80 (95% credibility interval (CI): 1.08-35.07), while EVLA, RR 0.06 (95% CI: 0.00-0.57), sclerotherapy, RR 0.07 (95% CI: 0.00-0.68) and RFA, RR 0.12 (95% CI: 0.01-0.91) were the 3 interventions reducing VLU recurrence. EVLA (SUCRA, 69.65) ranked as the most efficient intervention concerning ulcer recurrence reduction. Regarding postintervention complications, EVLA was the only intervention displaying a statistically-significant increased risk compared to compression monotherapy, RR 14.3 (95% CI: 2.03-172.56). Meta-regression analysis exploring the impact of perforator treatment on VLU failed to predict healing, ß = -0.27 (95% CI: -2.55 to 1.85), recurrence, ß = -0.02 (95% CI: -2.96 to 2.75) and complication outcomes, ß = -0.089 (95% CI: -3.13 to 2.85). During sensitivity analysis, RFA and sclerotherapy failed to sustain their effects on ulcer healing and ulcer recurrence, respectively. In addition, sclerotherapy displayed statistically-significant inferior outcomes compared to both EVLA and RFA regarding ulcer recurrence. CONCLUSION: This is the first network meta-analysis examining the effect of various interventions on VLU disease. While we have demonstrated the efficacy of RFA and ELVA in ulcer recurrence prevention, our results regarding the impact of RFA and sclerotherapy on VLU healing and recurrence, respectively, should be interpreted with caution. In addition, this review raises questions concerning the value of surgery and perforator interventions in the treatment of VLU. Further research through randomized controlled trials is required. CLINICAL IMPACT: Our review has revealed the significant efficacy of endovenous laser ablation (EVLA) and radiofrequency ablation (RFA) in effectively reducing the incidence of ulcer recurrence when compared to compression monotherapy. These outcomes hold the potential to provide relevant insights to both medical practitioners and patients, thereby informing a more prudent and enlightened decision-making approach. Such informed decisions, aimed at mitigating the recurring occurrence of venous leg ulcers, carry profound significance given the considerable socioeconomic implications associated with this medical condition.

Endovenous thermal ablation in the treatment of large great saphenous veins of diameters > 12 mm: A systematic review meta-analysis and meta-regression.

BACKGROUND: We sought to assess the safety and efficacy of endovenous thermal ablation (EVTA) in treating large great saphenous veins (GSV) > 12 mm in diameter. METHODS: We performed a systematic review according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) 2020 for comparative and noncomparative studies depicting EVTA in the treatment of GSV > 12 mm. Primary endpoints included GSV occlusion, technical success, deep vein thrombosis (DVT), and endovenous heat-induced thrombosis (EHIT). We conducted a comparative analysis between GSV > 12 mm and < 12 mm and a meta-regression analysis for two sets of studies, one including the whole dataset, containing treatment arms of comparative studies with GSV < 12 mm and one exclusively for GSV > 12 mm. RESULTS: Seven studies, including 2564 GSV, depicting radiofrequency (RFA) and endovenous laser ablation (EVLA) were included. GSV > 12 mm occlusion, technical success, DVT, and EHIT estimates were 95.9% (95% CI: 93.6-97.8), 99.9% (95% CI: 98.9-100.0), 0.04% (95% CI: 0.0-3.4), and 1.6% (95% CI: 0.3-3.5). Meta-regression revealed a negative association between GSV diameter and occlusion for both the whole dataset (p < 0.01) and the > 12 mm groups (p = 0.04), GSV diameter and technical success for both groups (p < 0.01), (p = 0.016), and GSV diameter and EHIT only for the whole dataset (p = 0.02). The comparative analysis between GSV < 12 mm and GSV > 12 mm displayed an occlusion estimate of OR 1.79 (95% CI: 1.25-2.56) favoring small GSV. CONCLUSION: Whereas we have displayed excellent occlusion and technical success results for the EVTA of GSV > 12 mm, our analysis has illustrated the unfavorable impact of GSV diameter on occlusion, technical success, and EHIT outcomes regardless of the 12 mm threshold. Potential parameter or device adjustments in a diameter-oriented fashion could further enhance outcomes.

Sporadic parathyroid adenoma: an updated review of molecular genetics.

Introduction: Primary HPT (PHPT) is a common disorder, affecting approximately 1% of the general population. Parathyroid adenomas emerge as non-familial sporadic in 90% of cases. The aim of this review is to give a detailed update of molecular genetics of sporadic parathyroid adenoma reported in international literature. Methods: A bibliographic research was conducted in PubMed, Google Scholar, and Scopus. Results: Seventy-eight articles were included in our review. CaSR, MEN1, CCND1/PRAD, CDKI, angiogenic factors like VEGF, FGF, TGFß, and IGF1, and apoptotic factors are important genes in parathyroid adenomas pathogenesis that have been established by several studies. A huge list of proteins is differently expressed in parathyroid adenomas measured by Western Blotting, MALDI/TOF, MS spectrometry, and immunohistochemistry. These proteins take part in several cell processes such as cell metabolism, cytoskeleton structural stability, cell oxidative stress regulation, cell death, transcription, translation, cell connection, and cell signaling transmission, while they can be found over- or underexpressed in abnormal tissues. Conclusion: This review gives a detailed analysis of all reported data on genomics and proteomics of parathyroid adenoma. Further studies should be applied on understanding parathyroid adenoma pathogenesis and introducing new biomarkers for early detection of primary hyperparathyroidism.

Interventions For the Treatment of Lower Limb Telangiectasias and Reticular Veins: A Systematic Review and Network Meta-Analysis.

OBJECTIVE: To assess the safety and efficacy of available interventions in the treatment of lower limb reticular veins and telangiectasias. DATA SOURCES: An electronic search was performed on Scopus, Embase, and Google scholar. REVIEW METHODS: A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Following data extraction and processing, a Bayesian network meta-analysis and meta-regression was undertaken. The primary endpoint was telangiectasia and reticular vein clearance. RESULTS: Nineteen studies, 16 randomised controlled trials and three prospective case series, including 1 356 patients and 2 051 procedures, were finally incorporated. All interventions, apart from 0.5% sodium tetradecyl sulphate (STS) and 0.25% STS displayed statistically significantly superior telangiectasia and reticular vein clearance compared with normal saline (N/S), Meta-regression analysis employing the type of the venule treated (telangiectasia or reticular vein) as a covariable, revealed a positive correlation between Nd:YAG 1064 nm laser and telangiectasia clearance (ß = 1.38, 95% CI 0.56 - 2.14). Further exploration unveiled the superiority of Nd:YAG 1064 nm in the treatment of telangiectasias compared with all included interventions except 72% chromated glycerin (CG). STS 0.25% increased the risk of hyperpigmentation compared with all interventions except 0.5% STS, and 1% polidocanol. CG 72% decreased the risk of matting compared with polidocanol foam (risk ratio [RR] 0.14, 95% CI 0.02 - 0.80) and STS (RR 0.31, 95% CI 0.07 - 0.92). Non-statistically significant differences were identified between interventions regarding pain outcomes. CONCLUSION: This network meta-analysis has demonstrated a proportional relationship between sclerosant potency and side effect occurrence in the treatment of telangiectasias and reticular veins and the superiority of laser therapy compared with injection sclerotherapy in treating telangiectasias. The transition of telangiectasia and reticular vein treatment from highly potent detergent solutions to equally effective but milder sclerosants could potentially reduce undesirable adverse events.

Minimally Invasive Treatments of Benign Thyroid Nodules: A Network Meta-Analysis of Short-Term Outcomes.

Background: Image-guided thermal ablation interventions are novel thermal-based modalities used for the treatment of benign thyroid nodules. Methods: We conducted a systematic review and a Bayesian network meta-analysis, examining studies using thermal ablation interventions in the treatment of benign nodular thyroid disease (PROSPERO CRD42022367680). The primary endpoints included volume reduction rate (VRR), and symptomatic score and cosmetic score improvement. Secondary endpoints included vocal disturbances, laryngeal nerve palsy, hypothyroidism, and nodular regrowth (defined by increased nodular volume of >50% for thermal ablation or new nodules arising in remaining thyroid tissue conventional surgery [CS]). Results: We included 16 studies (3 randomized controlled trials [RCTs] and 13 comparative case series), describing radiofrequency ablation (RFA), laser ablation (LA), microwave ablation (MWA), high-intensity focus ultrasound (HIFU), and CS, respectively. The review included data from 4112 patients followed for a mean of 11.9 months. Meta-analyses showed no significant differences among RFA, LA, MWA, HIFU, and CS regarding any of the primary endpoints of VRR, symptomatic score, and cosmetic score. In examining the surface under the cumulative ranking area (SUCRA) ranking, CS (SUCRA, 98.49), LA (SUCRA, 51.58), and MWA (SUCRA, 57.0) were identified as the three interventions that were most likely to result in the largest VRR, symptomatic and cosmetic score reduction. RFA, relative risk (RR) 0.19 [95% credibility interval (CI): 0.06 to 0.48], LA RR 0.23 [CI: 0.06 to 0.79], and MWA RR 0.25 [CI: 0.09 to 0.60] were associated with the greatest reduction in risk for postintervention vocal complications compared with CS, with RFA (SUCRA, 61.62) being ranked as the highest in safety. RFA RR 0.05 [CI: 0.00 to 0.40] and MWA RR 0.16 [CI: 0.02 to 0.73] were associated with a reduced risk of transient laryngeal nerve injury compared with CS. RFA RR 0.00 [CI: 0.00 to 0.00] and MWA RR 0.00 [CI: 0.00 to 0.03] were associated with a reduced risk of hypothyroidism occurrence compared with CS, with RFA (SUCRA, 99.86) yielding the highest safety ranking. RFA was associated with a reduced risk for nodular regrowth RR 0.09 [CI: 0.00 to 0.85], compared with CS. Conclusion: We have comprehensively reviewed the published literature on the efficacy and safety of thermal ablation modalities for benign thyroid nodules. Important research gaps remain regarding a paucity of both long-term data and high-quality RCTs.

Single Branched Endografts for the Preservation of Left Subclavian Artery in the Treatment of Zone II Thoracic Aortic Lesions a Systematic Review and Meta-Analysis.

BACKGROUND: We investigated the safety and feasibility of single branched endografts in the treatment of zone II thoracic endovascular aortic repair (TEVAR). METHODS: We performed a systematic research on Medline, Scopus and EMBASE for articles published up to February 2023. Primary end points included technical success, 30-day mortality, stroke and spinal cord injury (SCI) as well as unassisted left subclavian artery (LSA) branch patency by the end of follow-up. Secondary end points included early 30-day and persistent endoleaks, new onset dissection and reintervention by the end of follow-up. RESULTS: Fourteen studies, three prospective case series and 11 retrospective case series comprised of 727 patients were finally included. The pooled technical success and 30-day mortality rates were 94.86 % (95% confidence interval (CI): 90.95-97.86) and 0.14% (95% CI: 0.00-0.87). The 30-day stroke and SCI rates were 0.45% (95% CI: 0.00-1.39) and 0.08% (95% CI: 0.00-0.99), respectively, while the unassisted LSA branch patency estimate was 99.12% (95% CI: 97.97-99.86). The early 30-day and persistent endoleak rates were 5.19% (95% CI: 2.45-8.65) and 2.57% (95% CI: 0.36-6.02), whereas new onset dissections and reinterventions estimates were 0.94% (95% CI: 0.17-2.11) and 2.40% (95% CI: 0.41-5.42). CONCLUSIONS: While we have displayed the safety and feasibility of single branched endografts in the treatment of zone II thoracic aortic lesions, physicians should be aware of the persistency displayed by early type I endoleaks eventually requiring reintervention. The variations in device and lesion characteristics accompanied by the short-term follow-up presented in our review do not allow for definite conclusions to be drawn, necessitating further research through high-quality randomized controlled trials.

A network meta-analysis on the efficacy and safety of thermal and nonthermal endovenous ablation treatments.

OBJECTIVE: We assessed the mid-term efficacy and safety of thermal and nonthermal endovenous ablation for the treatment of lower limb superficial venous insufficiency. METHODS: We performed a systematic review in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement and a Bayesian network meta-analysis. The primary end points were great saphenous vein (GSV) closure and venous clinical severity score (VCSS) improvement. A meta-regression using GSV diameter as a covariate was undertaken for the two primary end points. RESULTS: We included 14 studies and 4177 patients, with a mean follow-up of 25.7 months. Radiofrequency ablation (RFA; odds ratio [OR], 3.99; 95% confidence interval [CI], 1.82-10.53), cyanoacrylate ablation (CAC; OR, 3.09; 95% CI, 1.35-8.37), and endovenous laser ablation (EVLA; OR, 2.72; 95% CI, 1.23-7.38) displayed increased odds for GSV closure compared with mechanochemical ablation (MOCA). MOCA inferiority compared with RFA (mean difference [MD], 0.96; 95% CI, 0.71-1.20), EVLA (MD, 0.94; 95% CI, 0.61-1.24), and CAC (MD, 0.89; 95% CI, 0.65-1.15) was also depicted regarding VCSS improvement. EVLA resulted in an increased risk of postoperative paresthesia compared with MOCA (risk ratio [RR], 9.61; 95% CI, 2.32-62.29), CAC (RR, 7.90; 95% CI, 2.44-38.16), and RFA (RR, 6.96; 95% CI, 2.31-28.04). Although the overall analysis identified nonstatistically significant differences for Aberdeen varicose vein questionnaire score improvement, thrombophlebitis, ecchymosis, and pain, further investigation revealed an increase pain profile for EVLA at 1470 nm compared with RFA (MD, 3.22; 95% CI, 0.93-5.47) and CAC (MD, 3.04; 95% CI, 1.05-4.97). A sensitivity analysis displayed a persistent underperformance of MOCA compared with RFA (OR, 4.33; 95% CI, 1.15-55.54) for GSV closure and both RFA (MD, 0.99; 95% CI, 0.22-1.77) and CAC (MD, 0.84; 95% CI, 0.08-1.65) regarding VCCS improvement. Although no regression model reached statistical significance, the GSV closure regression model revealed a trend for considerably decreased efficacy for both CAC and MOCA with larger GSV diameters compared with RFA and EVLA. CONCLUSIONS: Although our analysis has produced skepticism regarding the efficacy of MOCA in the mid-term period for VCSS improvement and GSV closure rates, CAC showed equivalent results compared with both RFA and EVLA. Additionally, CAC displayed a decreased risk of postprocedural paresthesia and pigmentation and induration compared with EVLA. Also, both RFA and CAC had an improved pain profile compared with EVLA 1470 nm. The potential underperformance of nonthermal, nontumescent ablation modalities in ablating large GSVs necessitates further research.

A Pilot Study of the Association VDR Polymorphisms With Primary Hyperparathyroidism.

BACKGROUND/AIM: Primary hyperparathyroidism (PHPT) is the third most common endocrine disorder characterized by autonomous parathyroid hormone (PTH) production from one or more parathyroid glands and hypocalcemia. Vitamin D through its receptor is a principal regulator of parathyroid glands function. VDR gene polymorphisms, which affect the expression or structure of VDR protein, may be involved in the genetic pathogenesis of PHPT. The aim of this study was to investigate the role of FokI, ApaI, TaqI, and BsmI VDR gene polymorphisms as genetic predisposing factors for PHPT. PATIENTS AND METHODS: Fifty unrelated patients with sporadic PHPT and an equal number of corresponding ethnicity, sex and age range healthy volunteers were enrolled in the study. Genotyping was performed with polymerase chain reaction and restriction fragment length polymorphism assay. RESULTS: Statistically significant difference was observed in TaqI genotype distribution between PHPT patients and controls, while no association was detected for the other studied polymorphisms. CONCLUSION: TaqI TT and TC genotypes may be associated with PHPT risk in Greek population. Further independent studies are needed to replicate and validate the role of VDR TaqI polymorphism in PHPT predisposition.
