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.

Attitude of the Older Population Toward Controlled Asystole Donation

INTRODUCTION

Studies about the knowledge of and attitude toward new lines of organ donation in a group of older people are important due to the increase in older organ donors.

OBJECTIVES

To analyze the attitude of citizens over 65 years of age in southeastern Spain toward controlled asystole donation (CAD) and to determine the psycho-social profile that influences this attitude.

METHODS

The study population consisted of citizens over 65 years of age. A representative sample was obtained in southeastern Spain (N = 420). A questionnaire about attitudes toward CAD was used, detailing in the questionnaire that this is a type of donation from people who have died of circulatory and respiratory criteria after the limitation of life support treatment. Several psychosocial variables were also taken into account. Statistical analysis included the χ2 test and multivariate analysis.

RESULTS

The completion rate was 84% (n = 351). Favorable attitude toward organ donation and transplantation (ODT) was 98% (n = 344) overall, and CAD was viewed favorably by 45% (n = 158). The psychosocial variables that influenced attitude toward CAD were mainly having received a talk about ODT (odds ratio [OR] 5.6), knowing the opinion of one's partner (OR 7.95), acceptance of cremation (OR 1.09), and acceptance of autopsy (OR 3.002).

CONCLUSIONS

The attitude of older people toward CAD is unfavorable despite a willingness to support ODT in general. This attitude is influenced by variables of social and family dialogue about ODT, attitude to body manipulation, and having received information about ODT.

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.

Teenagers, Audio-Visual Prosumers and Audience Generators in the Field of Organ Donation

The creation of audio-visual content and the increase in the use of social networks by society have provided new opportunities for promoting health and the benefits of organ donation. This study analyzes the influence of audiovisual content produced by adolescents in the context of an educational program related to the promotion of organ donation with diffusion through social media. The program was implemented in the fourth year (mainly 15 and 16 year olds) in ten high schools in Spain. In the first phase, students learn about donation and create audio-visual messages about its benefits for society; in the second phase, they share this content on social networks. The influence of the content was measured using YouTube Analytics. In addition, a questionnaire was administered after the program to measure the way in which they shared the content on social networks. A total of 391 students participated in program, submitting 63 short films that obtained 104,912 views. The short films focused on appealing to society about the need for organs and the benefits of the organ donation and transplantation process. The social network that was used most frequently to share the content was WhatsApp (81.8%). Educating teenagers and turning them into prescribers of the health benefits of the organ donation and transplantation process through the use of social networks could be a good tool that can be exported to other fields of health.

[Evaluation of the telematic consultation in endocrine surgery during confinement due to COVID-19]

BACKGROUND

The coronavirus disease pandemic of 2019 (COVID-19) made necessary to remodel the hospital's clinical consultations.

OBJECTIVE

To evaluate the telematic consultation in endocrine surgery, as well as to select the group of patients susceptible to perform a telematic consultation in the future according to this assessment.

METHODS

The study population were patients who had a clinical consultation by telephone. The evaluation was made with the Net Promoter Score (NPS).

STATISTICAL ANALYSIS

SPSS v.28, X² test and a multivariate analysis.

RESULTS

55 patients were analyzed. The NPS was +16, 24 promoters (43.6%) and 15 detractors (27.2%). There were differences between those whose main reason for consultation was malignant pathology (OR 4.5; p = 0.033). The NPS between malignant vs. non-malignant pathology was -13 vs. +38 (p > 0.001). The evaluation of the telematic consultations for the future was: telephone (83% very well), video call (58%), videoconference (19%).

CONCLUSIONS

The evaluation of the telephone consultation has been good, finding a better assessment among patients with non-malignant pathology. Its future implementation could be necessary, being the telephone the preferred way.

Film Creation for Education on Concepts Related to Religion, Immigration, and Legislation in the Field of Organ Donation and Transplantation

BACKGROUND

In education, we can use cinema to create methodologies that develop the critical thinking to acquire knowledge in a collaborative way. Favorable attitudes toward organ donation and transplantation (ODT) is low in adolescents. Working on topics related to ODT, such as religion, immigration, and the law, can help to improve students' knowledge and endear them toward ODT with innovative educational methodologies.

OBJECTIVES

This study aims to analyze the change in knowledge about religion, immigration, and legislation on ODT after an educational proposal based on film creation.

METHODS

In this study, 16-year-old students participated in an educational proposal based on ODT education through filmmaking. A total of 543 students participated in the experimental group, and 320 participated in the control group. A validated ODT knowledge form was administered to both groups. Statistical analysis was carried out with SPSS version 21.0 package (SPSS, Inc, Chicago, IL, USA). A descriptive analysis and χ² test were performed to analyze the differences between the experimental group and control group. P < .05 was considered statistically significant.

RESULTS

The study had a 72% participation rate in the experimental group. After receiving the educational proposal, the students presented a greater knowledge with respect to the control group in all aspects: the position of the different religions in relation to organ donation, knowledge of the rights and obligations of immigrants in relation to the ODT, and knowledge of the law of presumed consent in ODT CONCLUSIONS: Working in the classroom on psychosocial aspects such as religion, immigration, and legislation through filmmaking can favorably influence the adolescent's awareness of organ donation.

The Audiovisual Creation in Educational Proposals on Organ Donation: Attitude Towards Organ Donation and Transplantation of Secondary School Teachers

BACKGROUND

Audiovisual creation allows teachers and students to become consumers and producers of information, creating collaborative environments. In the field of organ donation and transplantation (ODT), most of the educational proposals analyzed to date consist of presentations. The teacher does not usually have a decisive role in this type of methodologies, in addition to not having the appropriate training to be able to participate actively.

OBJECTIVES

To analyze the change in teachers' attitudes towards ODT after participating in an educational proposal based on the creation of short films.

METHODS

Teachers of secondary education in ten schools in southeastern Spain. The proposal consisted in the creation of short films based on topics related to ODT by the students. A validated ODT attitude form was administered to teachers at the beginning of the proposal and at the end of the proposal. A descriptive analysis was carried out together with McNemar test was used to compare the pre and post test results of the teacher. P < .05 was considered statiscally significant.

RESULTS

The favorable attitude towards organ donation at death increased after the proposal (64% vs 88%; P = .008). Favorable attitude towards organ donation from a relative also improved (52% vs 76%; P = .008), as did favorable attitude towards living kidney donation (52% vs 88%; P < .001), living liver donation (36% vs 85%; P = .008) and xenotransplantation (45% vs 82%; P < .001).

CONCLUSIONS

The teachers improves after an educational proposal based on the creation of short films related to ODT.

Audiovisual Content to Promote Women Scientists on the YouTube Channels of Spanish Biosanitary Research Institutes

YouTube is an appropriate social network for disseminating scientific audiovisual content, and this content can help to make the position of women in science, and gender equality, more visible. The aim of this study is to analyse the visibility of women scientists on the YouTube channels of Spanish biosanitary research institutes accredited by the Instituto de Salud Carlos III. A mixed study of the channels and communication departments of the institutions has been carried out, analysing metrics of audience impact, the type of audiovisual production and the use of YouTube in the institution. Of the 1914 videos analysed, 4% (n = 76) of the content is related to the visibility of women scientists and has little impact. The audiovisual production is basic and informative, without a dramatic narrative structure and focused on transmitting the personal experiences of women scientists. It is necessary to invest resources in institutions to improve the production and dissemination of content that makes women in the scientific field more visible, especially among students.

The impact of information and communications technology and broadcasting on YouTube for improving attitude toward organ donation in secondary education with the creation of short films

OBJECTIVE

There is a lack of awareness about organ donation among teenagers, a fact that could decrease future donation rates. The objective is to analyze the impact of an educational proposal based on the creation of short films.

METHODS

Fifteen schools were randomly selected: ten for the experimental group (EG), and five for the control group (CG). In both groups all students from the selected classes participated (EG: n = 543, CG: n = 320). An intervention was undertaken in the EG, providing a website to make a short film about organ donation and transplantation (ODT) to be broadcast on YouTube. The students completed a questionnaire before and after the proposal.

STATISTICS

Mann-Whitney test was conducted to compare the pre-test data, McNemar test compare the pre and post test results of each group, and Chi-square test to compare the change in responses between the two groups.

RESULTS

The change to a more favorable response was greater in the EG in all variables. The YouTube channel received 104,912 viewings.

CONCLUSIONS

An innovative educational intervention has a positive influence on teenage attitude and knowledge about ODT; it also has important social repercussions.

PRACTICE IMPLICATIONS

Implementing this educational proposal about ODT could help improve future donation rates.

Malignant prediction in paragangliomas: analysis for clinical risk factors

INTRODUCTION

Paragangliomas are infrequent neuroendocrine tumours whose only criterion for malignancy is presence of metastases; thus, all paragangliomas show malignant potential. Actually, different risk factors have been analyzed to predict metastases but they remain unclear.

PURPOSE

To analyze clinical, histological, and genetic factors to predict the occurrence of metastasis.

PATIENTS AND METHOD

A multicentre retrospective observational analysis was performed between January 1990 and July 2019. Patients diagnosed with paraganglioma were selected. Clinical, histological, and genetic features were analyzed for the prediction of malignancy.

RESULTS

A total of 83 patients diagnosed with paraganglioma were included, of which nine (10.8%) had malignant paraganglioma. Tumour size was greater in malignant tumours than in benign (6 cm vs. 4 cm, respectively; p = 0.027). The most frequent location of malignancy was the thorax-abdomen-pelvis area observed in six cases (p = 0.024). No differences were observed in histological differentiation, age, symptoms, and catecholaminergic production. The most frequent genetic mutation was SDHD followed by SDHB but no differences were observed between benign and malignant tumours. In the univariate analysis for predictive factors for malignancy, location, tumour size, and histological differentiation showed statistical significance (p = 0.025, p = 0.014, and p = 0.046, respectively); however, they were not confirmed as predictive factors for malignancy in the multivariate analysis.

CONCLUSION

In this study, no risk factors for malignancy have been established; therefore, we recommend follow-up of all patients diagnosed with paraganglioma.

Uncommon tumors in multiple endocrine neoplasia (MEN) type 1: Do they have a relationship with the prognosis of these patients?

INTRODUCTION

The prognosis of MEN 1 patients is not only determined by pancreatic disease; it is also related to other uncommon tumors. The objective of this study is to analyze the tumors associated with MEN 1 outside the classic triad and to investigate their relationship with mortality.

MATERIALS AND METHODS

One hundred and five MEN 1 patients were studied in a tertiary referral hospital (1980-2019).

RESULTS

With a follow-up of 11 ± 4 years, seven patients died (8%), four as a consequence MEN syndrome. Thirty-three percent had adrenal gland tumors. One patient died of adrenal cancer. Eight percent presented with a neuroendocrine thoracic neoplasm, and one patient died. Another patient died due to cutaneous T-cell lymphoma. A further patient died because of a gastrinoma with liver metastasis.

CONCLUSIONS

To conclude, 75% of MEN-related deaths were the result of an uncommon pathology, and we, therefore, recommend that these tumors should be taken into account in the screening and follow-up of these patients.

Resilience Related to Quality of Life Perceived in Elderly Patients With Orthotopic Liver Transplant for More Than 10 Years

INTRODUCTION

Resilience is the ability to recover or adequately face adverse situations. It acts as a protective factor against negative events and/or complex stages of life, such as a chronic and complex disease requiring liver transplant. Age can also have an effect on a patient's ability to deal with liver transplant, resilience here being a predictor of well-being.

OBJECTIVE

To analyze the level of resilience and its relationship with health-related quality of life (HRQoL) in patients over 60 years of age who underwent an orthotopic liver transplant (OLT) more than 10 years ago.

MATERIALS AND METHODS

We conducted a cross-sectional descriptive study at the Hospital Clínico Virgen Arrixaca.

INSTRUMENT

1. To analyze resilience we used the Connor-Davidson Resilience Scale (CD-RISC 17) which measures 3 dimensions (tenacity/self-efficacy, personal control, and social competence). 2. To evaluate HRQoL, we used the Short Form-36 Health Survey (SF-36) questionnaire which covers 8 dimensions and produces 2 summary scores. Variables included age, sex, and post-OLT survival. Non-parametric statistical analysis was performed (P < .05).

RESULTS

We analyzed 47 patients, 68% men (n = 32). The average age was 70.85 ± 0.98 years and average post-OLT survival was 15.79 ± 0.78 years. In terms of resilience, men had higher scores in tenacity/self-efficacy (90.82 ± 2.71 vs 84.79 ± 3.49; P = .029) and personal control (82.5 ± 3.79 vs 69.33 ± 5.23; P = .023). The longer the post-OLT period, the less personal control (R = -0.298; P = .042). Regarding HRQoL, the dimension of personal control is positively related: physical function (R = 0.388; P = .007); general health (R = 0.429; P = .003); vitality (R = 0.560; P = .000); social function (R = 0.402; P = .005); mental health (R = 0.311; P = .034); and physical summary (R = 0.381; P = .008). Like social competence, it is related to mental health (R = 0.360; P = .013) and mental summary (R = 0.384; P = .008).

CONCLUSION

These patients showed adequate levels of resilience. A greater resilience is related to greater general health, vitality, social functioning, and mental health.

Attitude of Older People Toward Living Donation

BACKGROUND

Living donation is a potential source of organs that could help to reduce the organ transplant deficit. Given that we have a worldwide aging population, it is important to assess the opinion of older people toward this type of donation.

OBJECTIVES

To analyze the attitude of people aged > 65 years toward living kidney donation (LKD) and living liver donation (LLD) and to investigate the variables affecting their attitudes.

METHODS

A multicentric study was carried out using a representative sample of people > 65 years stratified by sex and geographic location in southeastern Spain (n = 420). The measurement instrument was a validated questionnaire about LKD and LLD. Statistics were analyzed using SPSS version 21.0 (IBM Corp, Armonk, NY, United States) software. Descriptive analysis was carried out using Student t test, χ² test, and a multivariate analysis.

RESULTS

The questionnaire completion rate was 84% (n = 351) with 88% (n = 310) in favor of LKD, and 89% (n = 311) in favor of LLD. Favorable attitude decreased to 3% when the donation under consideration was unrelated. Attitudes toward LKD and LLD were associated with having received information from the television (P = .016 and P = .045) and from friends (P = .017 and P = .03); accepting an autopsy after death (P = .001 and P = .002); and not being worried about scars (P = .015 and P = .044). In the multivariate analysis, the following variables continued to be significant: having received information from the television (odds ratio [OR], 2) and from friends (OR, 10.3); and the acceptance of an autopsy (OR, 2).

CONCLUSIONS

Older people are in favor of both LKD and LLD, assuming it is a related donation. In addition, the information the elderly population receives regarding organ donation and transplantation affects their attitudes.

The Influence of Mass Media on Organ Donation and Transplantation in Older People

BACKGROUND

Worldwide population aging has resulted in changes in the approach to the organ donation and transplantation (ODT) process, forcing us to include older people on transplant waiting lists and to assess older patients as potential donors. However, this is a sector of the population that has not been studied in great detail in terms of the information they receive about ODT.

OBJECTIVES

To analyze what kinds of media provide people > 65 years of age with information about ODT and which sources of information affect their attitude about this subject.

METHODS

A multicentric study was undertaken using a sample of people > 65 years of age stratified by sex and geographic location in southeastern Spain (n = 420). Questions about ODT and methods of receiving information were analyzed using a questionnaire. Statistical analysis was performed using SPSS version 21.0 (IBM Corp, Armonk, NY, United States). Descriptive analyses were performed with a Student t test and χ² test.

RESULTS

The questionnaire completion rate was 84% (n = 351). People aged > 65 years received information about ODT, mainly positive, from the television (82%), followed by films (35%), the radio (30%), the press (26%), family (26%), and friends (17%). Receiving information through one of the following sources was associated with a more favorable attitude toward organ donation: the family (76% vs 45%; P < .001), friends (77% vs 48%; P = .01), and the press (62% vs 49%; P = .034).

CONCLUSIONS

Older people mainly receive information about ODT from the mass media. However, social and family circles have the greatest influence on their attitudes toward organ donation.

Self-Esteem Related to Quality of Life in Patients Over 60 Years Old Who Received an Orthotopic Liver Transplantation More Than 10 Years Ago

BACKGROUND

Orthotopic liver transplantation (OLT) represents an improvement in the quality of life (QoL) in the short to medium term. However, there is little information about QoL in the long-term post-transplant and its relation with psychological variables such as self-esteem.

OBJECTIVE

To analyze the perceived QoL in relation to the level of self-esteem in patients over 60 years of age who received an OLT more than 10 years ago.

MATERIALS AND METHODS

Cross-sectional descriptive study. Including patients from the Hospital Clínico Universitario Virgen de la Arrixaca (HCUVA).

INSTRUMENT

to evaluate the QoL: EuroQol-5D questionnaire; to evaluate health status: 1. social transfer index and 2. visual analog scale (VAS); to measure self-esteem level: Rosenberg scale. Sociodemographic and clinical variables. Nonparametric analysis (P < .05).

RESULTS

Analyzed 46 patients, 70% men (n = 32) and 30% women (n = 14); mean age of 70.85 ± 6.7 years and mean years of post-OLT survival of 15.91 ± 5.3 years. Average score in QoL: 0.8 ± 0.17 in the social transfer index and 77.07 ± 16.82 in the VAS. Average level of self-esteem: 34 ± 3.55 point. When analyzing the variables, there are no differences in age or post-OLT years. There are significant differences according to sex (P = .001). However, the diagnosis influences the patient's perception of QoL (P < .001). The post-OLT survival correlates negatively with social transfer index (P = .017) and self-esteem level (P = .045). In addition, those patients living in the city presented a higher level of self-esteem (P = .03).

CONCLUSION

Sex, diagnosis, post-OLT years, social environment, and place of residence have an influence on the QoL and self-esteem of patients.

Knowledge of the Brain Death Concept Among Older People

BACKGROUND

The concept of brain death (BD) is not well understood in the general population; this lack of knowledge is one of the main factors that generates an attitude against organ donation. Older people are a population group that has rarely been studied in relation to organ donation and transplantation (ODT), and it is important to investigate the most important aspects of ODT, such as people's concept of BD.

OBJECTIVES

To analyze the level of understanding of the concept of BD in people > 65 years of age and the factors that influence their mode of thinking.

METHODS

A multicenter study was carried out with a representative sample of people > 65 years of age, stratified by sex and geographic location in the southeast of Spain (n = 420). Knowledge of BD as well as the influence of other variables were analyzed through a validated questionnaire about ODT. SPSS version 21.0 (IBM Corp, Armonk, NY, United States) software was used for statistical analysis. Descriptive analysis included Student t test and the χ² test.

RESULTS

The questionnaire had a completion rate of 84% (n = 351). In 36% (n = 127) of cases, people ˃ 65 years of age understood the concept of BD. In general, knowledge of this concept has not been associated with other variables including social-family interaction about ODT (P > .05).

CONCLUSIONS

Older people do not understand the concept of BD. It is, therefore, necessary to carry out informative campaigns on ODT explaining this concept. This would improve organ donation awareness in this particular group of people.

Psoas Muscle Index Does Not Predict Post-Transplant Outcomes: A Series of 57 Liver Transplant Recipients

BACKGROUND

Sarcopenia is defined as the loss of muscle mass and function. Our aim is to evaluate the degree of sarcopenia by measuring the patients on the waiting list for liver transplantation and its influence on the different post-liver transplant outcomes in our group.

METHODS

The psoas muscle index (PMI, cm²/m²) was calculated (right psoas muscle area [cm²]/the square of the body height [m²]) in 57 patients on the waiting list for liver transplantation in our center, and the post-transplant variables relevant to our study were collected.

RESULTS

The 57 recipients had a mean age of 57 years (range, 35-73) and had a mean of 7.4 months (range, 0-39) on the liver transplant waiting list. The mean psoas muscle index was 2.39 (range, 1-4), and the mean body mass index was 28.01kg/m² (range, 22-36). After multivariate analysis we found a positive correlation between the PMI and the body mass index of the recipients (r = 0.320, P = .017), intensive care unit length of stay, and donor age (r = 0.319, P = .042), and between cold ischemia time and graft survival (r = 0.366, P = .009). We found no correlation in our sample between PMI and post-liver transplant complications either in terms of graft or patient survival.

CONCLUSION

PMI is not representative of total muscle mass and sarcopenia and is not effective in adequately predicting the survival of patients on the waiting list for liver transplantation.

Impact of Hepatic Artery Thrombosis on the Success of a Liver Transplant Because of Hepatocellular Carcinoma

BACKGROUND

Hepatic artery thrombosis is one of the most serious complications after liver transplant. Our objective is to evaluate the impact of arterial thrombosis on the postoperative evolution of a series of patients who received transplants because of hepatocellular carcinoma.

METHODS

A retrospective study of 100 consecutive hepatocellular carcinoma liver transplants was performed from January 2011 to November 2017.

RESULTS

Of the 100 transplant recipients, we have observed hepatic artery thrombosis in 4 of them, 3 premature and 1 delayed. All of them received retransplants after diagnosis by hepatic artery ultrasonography and arteriography. The descriptive analysis showed a significant relationship between the appearance of hepatic artery thrombosis with variables of postoperative severity, such as arrhythmias, atelectasis, pleural effusion, hemodialysis requirement, acute kidney failure, and respiratory failure. Although patients with hepatic artery thrombosis had a longer mean hospital stay, this was not statistically significant. There was decreased graft survival and overall survival of patients who experienced hepatic artery thrombosis.

CONCLUSION

Although the incidence of hepatic artery thrombosis has been relatively low (4%), the early detection of risk factors, such as arterial anatomic anomalies that condition a complex anastomosis, should draw our attention, thus having at our disposal strict ultrasonography and arteriography surveillance protocols as well as prophylactic anticoagulation guidelines for receptors at risk.

Controlled donation after circulatory death up to 80 years for liver transplantation: Pushing the limit again

Our main objective was to compare liver transplant (LT) results between donation after circulatory death (DCD) and donation after brainstem death (DBD) in our hospital and to analyze, within the DCD group, the influence of age on the results obtained with DCD donors aged >70 years and up to 80 years. All DCD-LTs performed were analyzed prospectively. The results of the DCD group were compared with those of a control group who received a DBD-LT immediately after each DCD-LT. Later, the results obtained within the DCD group were analyzed according to the age of the donors, considering 2 subgroups with a cut-off point at 70 years. Survival results for LT with DCD and super rapid recovery were not inferior to those obtained in a similar group of patients transplanted with DBD livers. However, the cost of DCD was a higher rate of biliary complications, including ischemic cholangiopathy. Donor age was not a negative factor.

Psychological profile of teenagers toward organ donation: a multicentric study in Spain

Background

It is important for teenagers to have a favorable attitude toward organ donation and transplantation (ODT) in order to increase the number of future donors. To determine the attitude of teenagers in the South East of Spain toward ODT and to analyze the psychosocial variables related to this attitude.

Methods

The study population consisted of young teenagers in the South East of Spain. A stratified sample was selected by geographical location, sex and age (n = 4, 117). Attitude was assessed using a validated questionnaire about ODT (PCID-ODT Ríos). Statistical analysis: Student’s t-test, Chi-squared test and a multivariate analysis.

Results

The questionnaire completion rate was 87% (n = 3572). Attitude toward ODT was favorable in 46% of cases (n = 1633) and undecided in 43% (n = 1543). Several psychosocial variables had a favorable effect on donation: believing that one has good information about ODT (Odds Ratio [OR] 1.706); discussing the subject with the family (OR 1.543) and friends (OR 1.818); carrying out pro-social activities (OR 1.642); having a favorable attitude toward cremation (OR 1.466) and autopsy (OR 1.470); and, finally, not being afraid of scars (OR 4.184).

Conclusions

Teenagers in the South East of Spain are not currently inclined to support organ donation. This attitude is related to many psychosocial factors, mainly connected to not having good information about the subject, not discussing it in social circles and the fear of body mutilation. It would be appropriate to create educational interventional strategies in this group to prevent a negative impact on future donation rates.

Early Outcomes of Liver Transplantation Using Donors After Circulatory Death in Patients With Hepatocellular Carcinoma: A Comparative Study

INTRODUCTION

Donation after circulatory death (DCD) has increased in the last decade, although a slight increase in surgical complications has been reported in liver transplantation (LT). Therefore, DCD is not overall recommended because it entails an added risk. However, DCD in selected patients shows acceptable results.

OBJECTIVE

The objective was to analyze the characteristics, early outcomes, and survival at 1 year post-LT from a single institute (January 2015 to May 2017).

MATERIALS AND METHODS

We included 18 DCD-LTs and compared them with a control group of 18 donation after brain death (DBD) LTs. We analyzed pre- and posttransplant variables related to donors, recipients, and intraoperative early outcomes within patients transplanted due to hepatocellular carcinoma (HCC). A descriptive analysis, Mann-Whitney U test, χ², or Fisher test was performed when appropriate, as well as multivariate analysis in case of statistical significance. A variable is considered as statistically significant when it reaches a value of P < .05.

RESULTS

In DBD, we found a lower length of stay in the intensive care unit before retrieval and a higher rate of alcoholism and diabetes mellitus, Model for End-Stage Liver Disease score, and Child B and C score (P < .05). Most of the DCD were originally from the same LT recipient center, and a higher donor mean post-LT alanine aminotransferase level was found (P < .05). Survival for the DBD group was 88% and 75% in the DCD group at 1 year post-LT, being not significant (NS).

CONCLUSION

HCC recipients who are transplanted with good quality DCD livers do no worse than those transplanted with livers from DBD donors, although a good selection of them is crucial.

Donors Older Than 75 Years Do Not Influence the Appearance of Biliary Complications After Liver Transplantation

BACKGROUND

In recent years, several studies have shown that the age of the donor may be related to an increase in the occurrence of biliary complications (BCs), which remain the main cause of morbidity after liver transplantation. This study analyzed the type and management of these BCs, the impact of BCs on graft and patient survival rates, and the influence of some characteristics of donors and recipients on BC appearance in patients transplanted with donors 75 years of age or older.

PATIENTS AND METHODS

From 2003 to 2016, 100 liver transplantations with donors 75 years of age or older (15.6%) were performed in our hospital. The data were compared with a control group of 400 patients with younger donors (case-control 1:4 per chronology).

RESULTS

The BC rate in the group of patients transplanted with organs from elderly donors was 18%, compared to 21.5% in the control group. Specifically, in the immediate post-transplantation period, 14% of the elderly donor group and 13.8% of the control group presented some BCs, with no statistically significant differences in the incidence, type, and treatment of BCs between the two groups. The occurrence of BCs was not a factor associated with graft and patient survival rates. In the global population, donor death by cerebral vascular accident and male donors have influenced the occurrence of BCs.

CONCLUSIONS

The advanced age of the donor has not influenced BC rates after transplantation.

Primary hyperparathyroidism associated with MEN 1: Experience in 71 cases

INTRODUCTION

Primary hyperparathyroidism (pHPT) in MEN 1 is characterized by multiglandular disease and early involvement of parathyroid glands at different times. Persistence and recurrence range from 25%-35%. The purpose was: a) to describe the experience and the treatment of patients with pHPT in MEN 1; b) to analyze the variables related with clinical presentation and recurrence.

METHOD

A total of 97 patients with MEN 1 were diagnosed in a tertiary hospital. A retrospective analysis was made in patients with pHPT (n=71).

STUDY VARIABLES

age at diagnosis, mutation, clinical presentation, laboratory tests, surgical technique, and recurrence of HPT.

RESULTS

Mean age was 38 years, and 50 patients were asymptomatic. The surgical technique was: subtotal parathyroidectomy (n=55), resection of three glands (n=7), and resection of less glands (n=9). Transcervical thymectomy was performed in 53 patients. Mean follow-up was 102.9 months. There were 21 recurrences, There were correlations between age at diagnosis and serum calcium levels with the presence of symptoms (P<.0001). There were also correlations between recurrence and surgical technique (P<.03), non-association with thymectomy (P<.0001), and follow-up time (P<.03).

CONCLUSION

Performing genetic and clinical screening allows us to make a diagnosis in the asymptomatic period and to provide early treatment for HPT in MEN 1. The recurrence rate is high, and follow-up time and the surgical technique used are risk factors for recurrence.

Group Psychotherapy Could Improve Depression in Cirrhotic Patients on the Liver Transplant Waiting List

BACKGROUND

It is well-known that there is a high incidence of depression in patients on the liver transplant (LT) waiting list. However, there have been few studies of psychological intervention on these patients.

OBJECTIVES

To determine symptoms of depression in patients on the LT waiting list and the impact of group psychotherapy.

METHODS

Study population: patients on the LT waiting list who received group psychotherapy (n = 15).

CONTROL GROUP

patients who did not receive psychotherapy (n = 10). Measurement instrument: Beck's depression test, which was provided before psychotherapy was initiated and after it was completed (after 6 months). The control group was given the questionnaire at the same 2 points in time as the study group. The psychotherapeutic method consisted of discussing patients' feelings, which dealt with several matters related to transplantation. Different coping strategies were considered.

RESULTS

More than half of those surveyed initially had depressive symptoms. When the second survey was administered to the study population, all the patients improved in their psychopathological assessment. When the survey was administered to the control group, a worse psychopathological assessment was obtained in all cases.

CONCLUSIONS

Our data suggest an improvement in depressive symptoms in patients on the LT waiting list after receiving group psychotherapy.

Quality of Life and Group Psychological Intervention in Patients With Cirrhosis on Liver Transplant Waiting List

BACKGROUND

The patients on the liver transplant (LT) waiting list usually present with deterioration in their quality of life. Previous studies on psychological intervention have shown how the quality of life can be improved.

OBJECTIVE

To analyze preliminary results of the influence of group psychotherapy on the quality of life of patients on the LT waiting list.

METHOD

Fifteen patients on the LT waiting list who accepted receiving group psychotherapy were selected. The development of each 1 of these sessions was carried out at fortnightly periods for 6 months (12 sessions). Those patients who received a transplant and those patients who did not attend more than 6 group psychotherapy sessions were excluded. The Nottingham Health Profile was used to assess the quality of life. It consists of 38 items belonging to 6 health dimensions: energy, pain, physical mobility, emotional reaction, sleep, and social isolation. The study population was given a questionnaire before starting group psychotherapy and after it was finished.

RESULTS

Of the 15 patients selected from the study population, 3 patients were given a transplant before the psychotherapy had finished, and 5 patients were excluded for not having attended more than 50% of the sessions. Therefore, the study was completed on 7 patients (n = 7). Overall, a better assessment can be seen in the second questionnaire.

CONCLUSIONS

Group psychotherapy might favorably influence the quality of life of patients on the LT waiting list; therefore, it might be interesting to carry out studies on a larger scale in order to confirm these results.

Importance for the Elderly of Discussion in the Family and Society About Attitude Toward Organ Donation

BACKGROUND

The aging of the population has changed some of the approaches to the organ donation and transplant (ODT) process, such as considering elderly people as potential donors. We aimed to assess social and family discussions among the elderly about ODT and its effect on their attitude toward organ donation.

METHODS

A study was carried out at 2 publicly-funded social centers for the elderly. Contact was made with individuals >65 years of age (n = 120) to seek their participation in the study. A questionnaire was distributed to them with questions about ODT. A descriptive assessment was performed with the Student t test and χ² test used for statistical analysis.

RESULTS

The completion rate was 87% (n = 104). Of the respondents with a partner and children, 48% had discussed the topic of ODT. It was found that talking about the subject with one's partner, children, or friends had a favorable influence on attitude compared with when this was not done (93%, 86%, and 83% vs 19%, 30%, and 31%, respectively; P < .001). In addition, the opinion of one's partner and children toward ODT also had an influence; if favorable, the respondent's attitude was more favorable, compared with when they did not know their opinion (92% to 88% vs 58% to 37%, respectively; P < .001). Other ODT-related variables did not affect their attitude (P > .05).

CONCLUSIONS

Almost half of the elderly people had discussed ODT socially or with their family. This discourse has a favorable influence on their attitude toward organ donation and, therefore, it is important to encourage social and family dialog among this group.

Benefits of Group Psychotherapy in Cirrhotic Patients on the Liver Transplant Waiting List

INTRODUCTION

It is well-known that patients on the liver transplant (LT) waiting list experience a high rate of psychopathologic symptoms. However, few studies have been published about the use of group psychotherapy for these patients. We sought to assess (1) the psychopathologic data in patients on the LT waiting list and (2) the attitude toward a group psychotherapy procedure and its efficacy.

MATERIAL AND METHODS

In the pretransplant consultation phase, group therapy was offered to 20 patients on the LT waiting list. Patients who received psychotherapy were assessed previously using the Beck Depression Inventory.

RESULTS

Fifteen patients were included in the study. Significant differences were found between the psychopathologic assessment and the level of hepatopathy. In the first session, we observed that patients with hepatocarcinoma were much more reluctant to participate in the group therapy. In the second session, the group showed a high level of anxiety connected with a fear of transplantation. In the third session, a transplant physician answered all their questions, and at the end of the session patient anxiety had decreased. During the following sessions, family bonds and sharing experiences with other transplant patients were emphasized.

CONCLUSIONS

Patients were initially reluctant to participate in the group psychotherapy, although this changed as sessions proceeded. It is necessary to provide more information about the transplant procedure itself to decrease anxiety. Group therapy was valued positively by all patients who participated.

Papillary thyroid carcinoma and multiple endocrine neoplasia type 2

INTRODUCTION

Papillary thyroid carcinoma (PTC) is exceptional in MEN 2.

RESULTS

The analysis in 135 patients revealed two PTC, without C-cell pathology; both being positive for V804M mutation (RET proto-oncogene).

CONCLUSIONS

Few data are available about PTC in MEN 2, and without C-cell pathology is even less common. More studies are needed to correlate genetics and histology, and even for assessing PTC as only manifestation of MEN 2.
