Tumor microenvironment in thyroid cancer: Immune cells, patterns, and novel treatments.

The tumor immune microenvironment of thyroid cancer is the heterogeneous histological space in which tumor cells coexist with host cells. Published data from this review were identified by search and selection database of Pubmed, Elsevier, and Science Direct. Searching was made in two steps using different keywords. In thyroid pathology, the inflammatory response is very important, and might have a key role finding new diagnostic and therapeutic methods, particularly in thyroid cancer. Different immune cells may be more or less present in different types of thyroid cancer and may even have different functions, hence the importance of knowing their presence in different thyroid tumor pathologies. Cancer-related inflammation could be a useful target for new diagnostic and therapeutic strategies by analyzing peritumoral and intratumoral immune cells in different types of thyroid tumors. Moreover, novel strategies for thyroid cancer treatments, such as monoclonal antibodies targeting checkpoint inhibitors, are emerging as promising alternatives.

Improvement of mood and sleep quality in patients with primary hyperparathyroidism after parathyroidectomy: A prospective case-control study.

BACKGROUND: Primary hyperparathyroidism can impact patient quality of life with psychopathological symptoms like mood and sleep disturbances. In the latest recommendations published according to the primary hyperparathyroidism surgical consensus, these neuropsychological symptoms continue to be excluded. This study aims to assess the negative effects of mood and sleep on patients with primary hyperparathyroidism compared to healthy controls and analyze their improvement after surgery. METHODS: Prospective case-control study of patients with primary hyperparathyroidism. The Beck questionnaire and Pittsburgh Sleep Quality Index were used. The control group consisted of healthy people matched by age and sex. Preoperative results were compared with results at 3 and 12 months after surgery and compared with the control group. Statistical analysis consisted of the Kolmogorov-Smirnov test and Student's t test for correlations. RESULTS: Forty-nine patients who underwent parathyroidectomy were analyzed. In relation to depression, differences were observed between the results of the preoperative period and 3 months after surgery, with a significant decrease in depression score (16.80 ± 9.98 vs 13.08 ± 10.76; P = .001). This improvement was maintained after 1 year (P < .001). Regarding the quality of sleep, there were no differences 3 months after the intervention, but there were differences at 12 months (9.48 ± 4.76 vs 8.27 ± 4.38; P = .032). The dimensions of the Pittsburgh Sleep Quality Index were analyzed, observing significant differences only in daytime dysfunction after 3 months and 12 months after surgery (1.02 ± 0.99 vs 0.69 ± 0.82; P = .01 and 1.04 ± 0.98 vs 0.60 ± 0.76; P = .004). CONCLUSION: Mood changes and sleep quality improve after primary hyperparathyroidism surgery, although at different postoperative times, with this improvement being more pronounced in mood. This assessment should be taken into account in the preoperative consultation of patients with primary hyperparathyroidism.

The Influence of Hyperparathyroidism Patient Profile on Quality of Life After Parathyroidectomy.

BACKGROUND: Improvements in quality of life (QoL) after parathyroidectomy in patients with primary hyperparathyroidism (PHPT) is discussed. It has not been analyzed whether these improvements can be influenced by a specific socio-personal or clinical patient profile. OBJECTIVES: to analyze QoL differences after parathyroidectomy and to determine a socio-personal and clinical profile that influences improvement after parathyroidectomy. METHODS: A longitudinal prospective cohort study in patients with PHPT. SF-36 and PHPQOL questionnaires were completed by the patients. A comparative preoperatory analysis was carried out, at three and twelve months after surgery. Student's t test was used for the correlations. The size of the effect was assessed using G*Power software. A multivariate analysis was performed to evaluate the socio-personal and clinical variables affecting the improvement in QoL after surgery. RESULTS: Forty-eight patients were analyzed. Three months after surgery an improvement was found in physical function, general health, vitality, social function, emotional role, mental health and in the patient's declared health assessment. One year after the intervention a general improvement was observed, with a greater effect on mental health and declared health evolution. Patients with bone pain presented with a higher probability of improvement after surgery. Patients with prior psychological disease had a lower associated probability of an improvement and high levels of PTH related to a greater probability of improvement after surgery. CONCLUSIONS: There is an improvement in the QoL of PHPT patients after parathyroidectomy. Patients with bone pain and high PTH levels prior to the parathyroidectomy present with a greater probability of having a greater improvement in QoL after surgery.

Minimally invasive surgery and liver transplantation: is it a safe, feasible, and effective approach?

The minimally invasive approach (MIS) is undoubtedly one of the most important breakthroughs in surgery in recent decades. Consequently, MIS has been increasingly in the field of liver transplantation (LT). The objective of the present review was to determine the current status of MIS with respect to liver transplantation (LT) and what would be the indications for an MIS in this context today. The literature was searched for publications reporting the MIS in LT. Only those articles that described the results according to whether the MIS had been performed to treat transplant complications (urgent or late), another pathology not related to the LT, or to perform the liver explantation and graft implantation were included. From 2000 to 2022, 33 studies and 261 patients were included. Most frequent indications were incisional hernias secondary to LT followed by the treatment of other pathologies not related with the LT and treatment of LT complications. Only a 12% were urgent interventions. Few studies describe conversions with an average rate of 2.5%. Morbidity do not differ significantly from open surgery. No case of mortality or graft loss was described. Purely laparoscopic liver explants in 9 patients with 2 conversions and 3 cases of graft implantation with a higher warm ischemia in the MIS implants grafts were described. The limitations of MIS in LT are relative and probably depend more on training, experience, and skills of the surgeons. This approach could be safety and feasibility to solved complications or in other individualized indications in LT patients. The initial experiences in liver explant and graft implantation need further investigations.

Laparoscopic bile duct exploration during pregnancy: a multi-center case series and literature review.

BACKGROUND: The physiological changes of pregnancy increase the risk of gallstone formation and choledocholithiasis. Traditionally, endoscopic retrograde cholangiopancreatography (ERCP) has been the main approach for managing choledocholithiasis during pregnancy, but recent progress in laparoscopic bile duct exploration (LBDE) has demonstrated this technique as a safe and effective alternative option. METHODS: A retrospective multicenter study of all patients who underwent LBDE during pregnancy from five centers with proven experience in LBDE between January 2010 and June 2020 was performed. The primary endpoint was to analyze the role of LBDE during pregnancy and to further characterize its position as a safe and effective alternative for the management of choledocholithiasis. A systematic review of the published literature relating to LBDE during pregnancy until February 2022 was also performed. RESULTS: Five institutions reported performing LBDE during pregnancy in 8 patients. Median surgical time was 75 min (range: 60-140 min). The bile duct was cleared successfully in all patients, and the median hospital stay was 2 days (range: 1-3 days). The literature review identified a total of 7 patients with a successful CBD clearance rate of 86%. There were no major maternal, fetal, or pregnancy-related complications in any of the total 15 patients included. The symptomatic common bile duct lithiasis with deranged liver function tests was the most frequent indication (n=7). CONCLUSION: LBDE during pregnancy appears to be safe and effective. More evidence reporting outcomes of LBDE during pregnancy is needed before any strong recommendations can be made.

Quality of life, mood and sleep quality in patients with primary hyperparathyroidism. Impact of socio-personal and clinical profile.

INTRODUCTION: Quality of life (QoL) in patients with primary hyperparathyroidism (PHPT) can be negatively affected by the disease, and it is important to identify risk factors. The objectives of the present study were to analyze QoL, mood and quality of sleep in patients with PHPT and to determine the impact of socio-personal and clinical variables. PATIENTS AND METHOD: The study group included patients diagnosed with PHPT, and the control group was taken from general population, paired by age and gender. QoL was analyzed using the SF-36 and the PHPQoL questionnaires. The Beck-II and Pittsburg questionnaires were used to assess depression and sleep quality. Socio-personal and clinical variables were analyzed. Statistical analysis on SPSS software v.28 used the Student t-test, ANOVA, Pearson's rank correlation, Mann-Whitney test, Kruskal-Wallis test and Spearman's rank correlation. A multiple linear regression model of the QoL was constructed. RESULTS: Sixty-five patients with PHPT were analyzed. A greater negative effect on QoL, mood and sleep quality were observed in patients with PHPT than in controls (P<0.05), with a good correlation between the various questionnaires. Several socio-personal variables had an effect on QoL and mood (P<0.05). QoL in patients with PHPT was affected by educational level, having offspring, and psychological symptoms (P<0.05). CONCLUSIONS: Patients with PHPT had poorer QoL and greater neurocognitive disorder than the general population. Socio-personal profile should be taken into account in the clinical assessment of these patients, together with psychological symptoms.

The New Age of Organ Donation-What Factors Have an Influence on the Attitude of Older People? An Attitudinal Survey in Southeastern Spain.

Currently, more than half of all donors are aged over 65 years, and previous studies have shown that this group is less willing to support organ donation. Objective: to analyse the attitude of people aged over 65 years toward organ donation and transplantation (ODT) and to determine how their psychosocial profile affects their attitude. Study population: citizens residing in southeastern Spain older than 65 years of age. A representative sample was obtained, which was stratified by gender and geographical location (n = 420). A validated questionnaire about ODT was used. Statistical analysis: a bivariate analysis was performed using the X2 test and a multivariate analysis. The favourable attitude toward the donation of one's own organs was 53%. The psychosocial variables affecting attitude were mainly: having discussed ODT with one's family (p < 0.001) or friends (OR 2.223), acceptance of cremation (OR 2.508), and acceptance of an autopsy (OR 2.578). Citizens aged over 65 tend to have an unfavourable attitude toward the donation of their own organs. The lack of dialogue about ODT in social and family settings, and the attitude to the manipulation of one's own body after death, are aspects of a respondent's psychosocial profile, which influence this attitude.

Learning Curve for Laparoscopic Sleeve Gastrectomy: a Cumulative Summation (CUSUM) Analysis.

PURPOSE: Bariatric surgery is currently considered the most effective and durable treatment option for morbid obesity. Laparoscopic sleeve gastrectomy (LSG) has become a popular technique and may currently be the most frequently practiced surgical operation to treat obesity. However, no objective analyses of its learning curve have been reported. OBJECTIVE: to analyze the learning curve for LSG. MATERIALS AND METHODS: We included all LSGs performed in our hospital (University Hospital, Spain; Public Practice) from April 2013 to February 2016. The learning curve for LSG was evaluated using cumulative sum (CUSUM) analysis. All variables among the learning curve phases were compared. RESULTS: According to the CUSUM analysis, the learning curve was divided into three unique phases: early learning (the initial 26 patients), acquisition of skills (the middle 30 patients), and mastery of technique (the final 56 patients). The operative time and gastric stenosis significantly decreased with progression of the learning curve without differences in the 30-day postoperative complication rate, postoperative stay, or weight loss. CONCLUSION: According to this study, the learning curve for LSG can be divided into 3 distinct phases, and about 25 patients are needed to demonstrate an improvement in surgical skill.

Esophageal stricture as an initial manifestation of Crohn's disease.

Crohn's disease located in the esophagus is rare, being exceptional as the initial manifestation of the disease. Erosive ulcerative esophagitis, stricture and fistula are forms of presentation, as in other esophageal pathologies, so the differential diagnosis is broad. The histologic features of esophageal Crohn's disease can be nonspecific and increase the diagnostic challenge. Esophageal Crohn's disease should be included in the differential diagnosis of esophageal strictures and may require esophagectomy if medical-endoscopic treatment is not effective.

Are We Ready for Bariatric Surgery in a Liver Transplant Program? A Meta-Analysis.

BACKGROUND: Obesity-related non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are two main causes of end-stage liver disease requiring a liver transplantation. Studies exploring bariatric surgery in the liver transplantation setting have increased in recent years; however, a systematic analysis of the topic is lacking to date. This meta-analysis was conducted to explore the perioperative and long-term outcomes of bariatric surgery in obese patients undergoing liver transplantation. METHODS: Electronic databases were systematically searched for studies reporting bariatric surgery in patients undergoing liver transplantation. The primary outcomes were postoperative complications and mortality. We also extracted data about excess weight loss, body mass index, and improvement of comorbidities after bariatric surgery. RESULTS: A total of 96 patients from 8 articles were included. Bariatric surgery-related morbidity and mortality rates were 37% (95% CI 0.27-0.47) and 0.6% (95% CI 0.02-0.13), respectively. Body mass index at 24 months was 31.02 (95% CI 25.96-36.09) with a percentage excess weight loss at 12 and 24 months of 44.08 (95% CI 27.90-60.26) and 49.2 (95% CI 31.89-66.66), respectively. After bariatric surgery, rates of improvement of arterial hypertension and diabetes mellitus were 61% (95% CI 0.45-0.75) and 45% (95% CI 0.25-0.66), respectively. In most patients, bariatric surgery was performed after liver transplant and the most frequent technique was sleeve gastrectomy. CONCLUSIONS: Bariatric surgery can be performed safely in the setting of liver transplantation resulting in improvement of obesity-related comorbidities. The optimal timing and technique require further studies.
