Prevalence of hyperthyroidism and hypothyroidism in liver transplant recipients and associated risk factors.

The prevalence of hyperthyroidism and hypothyroidism and associated risk factors are unknown in liver transplant recipients. We aimed to determine the prevalence of hyperthyroidism and hypothyroidism and associated risk factors in liver transplant recipients and to compare it with controls from the general population. As part of the Danish Comorbidity in Liver Transplant Recipients (DACOLT) Study, all Danish liver transplant recipients over the age of 20 were invited for measurements of concentrations of thyrotropin and thyroid hormones. The prevalence of hyperthyroidism and hypothyroidism was compared to age- and sex-matched controls from the Copenhagen General Population Study. Using logistic regression adjusted for age, sex, smoking, and body-mass index, we investigated potential risk factors. We recruited 489 liver transplant recipients and 1808 controls. Among liver transplant recipients, 14 (2.9%) had hyperthyroidism compared with 21 (1.2%) of controls (adjusted odds ratio [aOR] 2.24, 95% confidence interval [CI] 1.05-4.75, P = 0.04), while 42 (5.7%) had hypothyroidism compared with 139 (7.7%) of controls (aOR 0.68, 95% CI 0.43-1.08, P = 0.10). Female sex, and autoimmune hepatitis and primary sclerosing cholangitis as causes of transplantation were associated with hyperthyroidism after adjustments. Age, female sex, and autoimmune liver diseases as cause of transplantation were associated with hypothyroidism after adjustments. DACOLT is registered in ClinicalTrials.gov (NCT04777032).

Have a vital end-user been overlooked? Developing a shared decision intervention for patients with potential pancreatic cancer regarding the choice of surgery.

Objective: To develop a patient decision aid facilitating shared decision making for patients with potential pancreatic cancer deciding about no treatment, surgical or medical treatment. Methods: Based on a user-centred design by Wittemann et al., we developed a shared decision making intervention in three phases: 1) Understanding decision needs 2) Development of a patient decision aid (PtDA) based on a generic template 3) Assessment of the intervention from interviews with patients (n = 11), relatives (n = 11), nurses (n = 4) and surgeons (n = 2) analysed with thematic analysis, and measuring patients' perceptions of choice of options with the Decisional Conflict Scale. Results: Results showed varying experiences with the use of the PtDA, with surgeons not finding PtDA useful as it was impractical and constraining with patients' conversations. There was no difference in patients' perceptions in choosing options for those being presented vs those patients not being presented for the PtDA. Conclusion: The format and structure of the PtDA was not feasible for the surgeons as fundamental users in the present clinic. Innovation: This study highlights the urgent need to consider clinical context before introducing a predefined tool and shows the importance of a multistakeholder approach. Research should focus on finding means to successful implement shared decision making.

Self-reported symptom occurrence and distress, and psychological well-being after liver transplantation - a descriptive cross-sectional study of Danish recipients.

Introduction: Symptom distress and impaired psychological well-being after liver transplantation may lead to limitations in everyday activities and lowered health-related quality of life. The aim of this nationwide, descriptive, and cross-sectional study was to explore self-reported symptom occurrence and distress, among Danish liver transplant recipients, and their association with self-reported psychological well-being as well as demographic, and clinical characteristics. Methods: Liver transplant recipients transplanted from 1990 to 2022 were included. All recipients were asked to complete the Organ Transplant Symptom and Wellbeing instruments consisting of two instruments measuring self-reported symptom occurrence and distress, respectively, as well as self-reported psychological well-being by the Psychological General well-being instrument. Results: Of 511 invited recipients 238 responded: 116 women and 122 men with a median post-transplant follow-up of 7.5 years (IQR 3.6-14.2 years). The most common single symptoms reported were decreased libido (18%), diarrhea (10%), and headache (8%). Sleep problems were the most common transplant-specific domain. 41% of the recipients reported poor psychological well-being, especially those who had undergone transplantation within the last 5 years, women, and younger recipients. Discussion: In the interest of equity, the fact that women reported a higher level of symptom distress than men requires attention. Research on symptom management support is warranted with interventions focusing on how to alleviate symptom distress, which might increase long-term survival, which has not improved in recent decades.

Anemia in liver transplant recipients: prevalence, severity, risk factors, and survival.

Information about anemia in liver transplant (LTx) recipients is scarce. We investigated the prevalence and severity of anemia before and within the first-year post-LTx, risk factors for having anemia before LTx, and 1-year survival according to anemia status before LTx. This retrospective cohort study received data from The Knowledge Center for Transplantation database at Rigshospitalet, Copenhagen, Denmark. Uni- and multivariate logistic regression were used to investigate factors associated with anemia and a Kaplan-Meier plot to illustrate the probability of survival. We included 346 first-time adult LTx recipients. The median age was 50 years (IQR: 42-57), and 203 (59%) were male. The prevalence of anemia before and 1-year post-LTx were 69 and 45%, respectively. Male sex (aOR 4.0 [95% CI: 2.2-7.2]; p < 0.001) and each unit increase in MELD score (aOR 1.2 [95% CI: 1.1-1.2]; p < 0.001) were positively associated with anemia before LTx. Compared to autoimmune liver diseases, LTx recipients with fulminant hepatic failure (aOR 0.03 [0.00-0.17]; p = 0.001) had lower odds for anemia. The 1-year survival in LTx recipients who had and did not have anemia before transplantation were 93 and 91% (p = 0.47). Anemia was frequent among LTx recipients, and anemia before LTx did not affect 1-year survival.

Robot-assisted minimally invasive liver surgery in elderly patients: A single-centre, propensity score- matched study.

BACKGROUND: The aim was to evaluate the short-term results of robot-assisted minimally invasive liver surgery(Robot-assisted liver surgery (RLS)) in elderly patients. METHODS: Between November 2019 and July 2022, RLS was performed on 100 consecutive patients. Patients were divided into a middle-aged group (Group1:＜75years) and an elderly group(Group2:≧75years). A propensity score matching(PSM) analysis with a ratio of 1:1 was performed. RESULTS: After PSM, there were 28 patients in each group. There were no significant differences in clinicopathologic characteristics, type of resection and intraoperative variables. Postoperative complications and length of hospital stay were comparable in Groups 1 and 2. In a comparison between minor and major hepatectomy in Group 2, there were no significant differences in any of the factors. CONCLUSIONS: The study showed that RLS for patients over 75years had similar short-term outcomes as for younger patients down to middle-aged, especially the risk of perioperative complications was comparable.

Herpesvirus immunology in solid organ transplant recipients - liver transplant study (HISTORY): a retrospective and prospective observational cohort study.

BACKGROUND: Life-long immunosuppressive treatment after liver transplantation (LT) prevents graft rejection but predisposes the LT recipient to infections. Herpesvirus infections are associated with morbidity and mortality among LT recipients. Among those, especially cytomegalovirus (CMV) and varicella-zoster virus (VZV) pose challenges after LT. The aim of this study is to provide an in-depth characterization of the cellular immune response against CMV and VZV infections in LT recipients and identify potential risk factors for infection. METHODS: The Herpesvirus Infections in Solid Organ Transplant Recipients - Liver Transplant Study (HISTORY) consists of an epidemiological and immunological substudy. The epidemiological substudy is a retrospective observational cohort study that includes all patients who underwent LT in Denmark between 2010 and 2023 (N ≈ 500). Using data from nationwide hospital records and national health registries, the incidence of and clinical risk factors for CMV and VZV infections will be determined. The immunological substudy is an explorative prospective observational cohort study including patients enlisted for LT in Denmark during a 1.5-year period (N > 80). Participants will be followed with scheduled blood samples until 12 months after LT. CMV- and VZV-derived peptides will be predicted for their likelihood to be presented in participants based on their HLA type. Peptide-MHC complexes (pMHC) will be produced to isolate CMV- and VZV-specific T cells from peripheral blood mononuclear cells before and after CMV and VZV infection. Their frequency, T cell receptor sequences, and phenotypic characteristics will be examined, and in a subset of participants, CMV- and VZV-specific T cells will be expanded ex vivo. DISCUSSION: This study will provide novel insight into T cell immunity required for viral control of CMV and VZV and has the potential to develop a prediction model to identify LT recipients at high risk for infection based on a combination of clinical and immunological data. Furthermore, this study has the potential to provide proof-of-concept for adoptive T cell therapy against CMV and VZV. Combined, this study has the potential to reduce the burden and consequence of CMV and VZV infections and improve health and survival in LT recipients. TRIAL REGISTRATION: ClinicalTrials.gov (NCT05532540), registered 8 September 2022.

Physical and psychological symptom burden in patients and caregivers during follow-up care after curative surgery for cancers in the pancreas, bile ducts or duodenum.

BACKGROUND: The primary aim was to assess Health Related Quality of Life (HRQoL), anxiety and depression in patients and caregivers during follow-up care after curative treatment for cancer in the pancreas, duodenum, or bile ducts. The secondary aim was to assess dyadic coping and the burden of being a caregiver. MATERIALS AND METHODS: In this prospective observational cohort study, we included patients and caregivers at first follow-up visit to conduct the following: Demographic characteristics, The European Organization for Research and Treatment of Cancer Quality of Life, the pancreas and bile duct module, EQ5D 3L, GAD-7 and PHQ-9 at baseline, and at six and nine-months follow-up visit. Demographic characteristics, Dyadic Coping Inventory and Zarit Caregiver Burden Questionnaire were conducted at baseline and at nine-months of follow-up visit. RESULTS: The response rate was 42% with 104 of the 248 invited patients completing the questionnaires at baseline: 78 (75% of 104) after six and 69 (66% of 104) after nine months. The median (Q25,75) time for inclusion was 33.6 (13.4, 38) and 29.1 (18.3, 36) weeks after surgery for patients with pancreatic or duodenal cancer, and bile duct cancer, respectively. The response rate of caregivers was 88% with 75 of 85 completing the questionnaires. Fifty percent of patients with pancreatic or duodenal cancer had diarrhea at baseline. After six and nine months, this increased to 75%. Fatigue was the most prominent symptom in patients with bile duct cancer after nine months with 25% of patients scoring this as a clinical symptom. CONCLUSIONS: The study highlights the need to systematically screen physical and psychological symptoms in patients and caregivers during follow-up care after treatment for cancer in the pancreas, duodenum and bile ducts. Symptom management during follow-up care should be prioritized by clinicians.

Characteristics of de novo cancer in liver transplant recipients.

Liver transplant recipients receive immunosuppressive treatment to avoid organ rejection, increasing the risk of developing de novo cancer after transplantation. We investigated the cumulative incidence of de novo cancer in a cohort of Danish liver transplant recipients. The study was a retrospective cohort study of adult liver transplant recipients transplanted at Rigshospitalet, Copenhagen, Denmark, between January 1, 2010, and December 31, 2019. De novo cancer was defined as cancer arising at least 30 days after liver transplantation, excluding relapses from prior cancers and donor-derived cancers. We determined the incidence of de novo cancer in the cohort using the Aalen-Johansen estimator, with death and retransplantation as competing risks. We included 389 liver transplant recipients and identified 47 recipients (12%) with de novo cancer after liver transplantation, including 25 recipients with non-melanoma skin cancers. The cumulative incidences at 5 years after liver transplantation for all cancers and non-skin cancers were 10.7% and 4.9%, respectively. De novo cancer after liver transplantation is relatively common, with the majority being non-melanoma skin cancer. Future studies of sufficient size are needed to identify risk factors for de novo cancer after liver transplantation.

Learning curves in robot-assisted minimally invasive liver surgery at a high-volume center in Denmark: Report of the first 100 patients and review of literature.

BACKGROUND AND OBJECTIVE: Minimally invasive liver surgery is evolving worldwide, and robot-assisted liver surgery (RLS) can deliver obvious benefits for patients. However, so far no large case series have documented the learning curve for RLS. METHODS: We conducted a retrospective study for robotic liver surgery (RLS) from June 2019 to June 2022 where 100 patients underwent RLS by the same surgical team. Patients' variables, short-term follow-up, and the learning curve were analyzed. A review of the literature describing the learning curve in RLS was also conducted. RESULTS: Mean patient age was 63.1 years. The median operating time was 246 min and median estimated blood loss was 100 mL. Thirty-two patients underwent subsegmentectomy, 18 monosegmentectomies, 25 bisegmentectomies, and 25 major hepatectomies. One patient (1.0%) required conversion to open surgery. Five patients (5%) experienced postoperative major complications, and no mortalities occurred. Median length of hospital stay was 3 days. R0 resection was achieved in 93.4% of the malignant cases. The learning curve consisted of three stages; there were no significant differences in operative time, transfusion rate, or complication rate among the three groups. Postoperative complications were similar in each group despite an increase in surgical difficulty scores. The learning effect was highlighted by significantly shorter hospital stays in cohorts I, II, and III, respectively. The included systematic review suggested that the learning curve for RLS is similar to, or shorter, than that of laparoscopic liver surgery. CONCLUSIONS: In our experience, RLS has achieved good clinical results, albeit in the short term. Standardization of training leads to increasing proficiency in RLS with reduced blood loss and low complication rates even in more advanced liver resections. Our study suggests that a minimum of 30 low-to-moderate difficulty robotic procedures should be performed before proceeding to more difficult resections.

Enhanced recovery after surgery is feasible and safe in liver transplantation: a cohort study.

BACKGROUND: The principles of enhanced recovery after surgery (ERAS) are being applied to still more advanced procedures. Liver transplantation offers a unique opportunity for a multimodal approach including donor care as well. Our objective was to determine if ERAS was applicable and safe in orthotopic liver transplantation (OLT). METHODS: A national single centre retrospective study showing the implementation of ERAS from 2013 to 2019 with the proceeding 2 years serving as baseline. The primary endpoints were mortality, length of stay (LOS) in the ward and intensive care unit stay. Secondary endpoints were complications estimated by Dindo-Clavien classification, comprehensive complication index (CCI®) and re-admissions. RESULTS: A total of 334 patients were included. LOS was significantly reduced from a median of 22.5 days at introduction to 14 days at 2019. Cold ischaemia time was reduced from a mean of 10.7 to 6.0 h and the use of blood products (erythrocytes, plasma and thrombocytes) from a median of 28 to 6 units. Complications were reduced in severity. Mortality and readmission rates were not affected. CONCLUSION: ERAS principles are safe and recommended in patients undergoing OLT resulting in reduced severity of complications and LOS without affecting re-admissions or mortality.

Robotic liver resection in Denmark: Report of the first 50 cases at Rigshospitalet Copenhagen.

While most centers around the globe still consider open hepatic resection as the standard, innovative centers step in light of future developments of the robotic platform forward and introduce a robotic liver program while skipping the laparoscopic approach for its technological flaws. This applies also for our Department of Surgery and Transplantation at Rigshospitalet, Copenhagen University Hospital in Denmark. We herewith present as-to our best knowledge-the first center in Scandinavia our experience with the initial 50 robotic liver resections.

Pancreatic surgery during the COVID-19 pandemic 2020-2021: an observational cohort study from a third level referral center.

BACKGROUND: During the COVID pandemic there has been limited access to elective surgery including oncologic surgery in several countries world-wide. The aim of this study was to investigate if there was any lockdown effect on pancreatic surgery with special focus on malignant pancreatic and periampullary tumours. METHODS: Patients who underwent pancreatic surgery during the two Danish lockdown periods from 11. March 2020 and the following 12 months were compared with patients who were operated the preceding 3 years. Data on patients' characteristics, waiting time, operations, and clinical outcomes were evaluated. RESULTS: During lockdown and the previous three years the annual number of resections were 242, 232, 253, and 254, respectively (p = 0.851). Although the numbers were not significantly different, there were fluctuations in operations and waiting time during the lockdown. During the second outbreak of COVID October 2020 to March 2021 the overall median waiting time increased to 33 days (quartiles 26;39) compared to 23 (17;33) days during the first outbreak from March to May 2020 (p = 0.019). The same difference was seen for patients with malignant tumours, 30 (23;36) vs. 22 (18;30) months (p = 0.001). However, the fluctuations and waiting time during lockdown was like the preceding three years. Neither 30- nor 90-days mortality, length of stay, number of extended operations, and complications and tumour stage were significantly different from previous years. CONCLUSIONS: There were significant fluctuations in waiting time for operations during the lockdown, but these variations were not different from the preceding three years, wherefore other explanations than an impact from COVID are conceivable.

High-dose preoperative glucocorticoid for prevention of emergence and postoperative delirium in liver resection: A double-blinded randomized clinical trial substudy.

BACKGROUND: Emergence delirium (ED) and postoperative delirium (POD) are associated with increased morbidity and mortality and occur in up to one-third of patients undergoing major non-cardiac surgery, where the underlying pathogenesis is multifactorial, including increased inflammation. We aimed to assess the effect of pre-operative high- versus low-dose glucocorticoid on the occurrence of ED and POD. METHODS: This was a substudy from a randomized, double-blinded clinical trial. Patients ≥18 years, undergoing open liver resection were randomized 1:1 to high-dose (HD, 10 mg/kg methylprednisolone) or low-dose (LD, 8 mg dexamethasone) glucocorticoid and assessed for ED and POD for a maximum of 4 days during hospitalization. The 3-min Diagnostic Interview for CAM-defined delirium (3D-CAM) was used for assessment, 15 and 90 min after arrival in the post-anesthesia care unit (PACU), and subsequently once daily in the ward. RESULTS: Fifty-three patients were included in this secondary substudy (26 HD-group and 27 LD-group). ED occurred in n = 5 HD versus n = 6 LD patients 15 min after PACU arrival. At 90 min after PACU arrival, 4 patients had ED, all from LD-group, and resulted in significantly longer PACU admission, 273 versus 178 min in ED versus Non-ED patients. During the first 4 days in the ward, n = 5 patients had at least one occurrence of POD, all from LD-group. CONCLUSIONS: The primary finding of the current substudy was a lower occurrence of ED/POD in the PACU 90 min after arrival and during the first four postoperative days in patients receiving high-dose glucocorticoid compared with patients receiving low-dose glucocorticoid. The two study groups were not evenly balanced concerning known explanatory factors, i.e., age and size of surgery, which calls for larger studies to elucidate the matter.

Does multimodal perioperative pain management enhance immediate and short-term outcomes after living donor partial hepatectomy? A systematic review of the literature and expert panel recommendations.

BACKGROUND: The optimal analgesic strategy for patients undergoing donor hepatectomy is not known and the potential short- and long-term physical and psychological consequences of complications are significant. OBJECTIVES: To identify whether a multimodal approach to pain of the donor intraoperatively enhances immediate and short-term outcomes after living liver donation, and to provide international expert panel recommendations. DATA SOURCES: Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central. METHODS: Systematic review following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel. PROSPERO 2021 CRD42021260699. RESULTS: Nine studies assessing multi-modal analgesia strategies were included in a qualitative assessment. Interventions included local, regional, and neuro-axial anesthetic techniques, pharmacological intervention (NSAIDs, COX-2 inhibitors, ketamine, dexmedetomidine, and lidocaine), and acupuncture. Overall, there was a significant (40%) reduction in opioid requirement on day 1 and a significant reduction in pain scores in the intervention vs control groups. Significant reductions in either length of stay or post-operative complications were demonstrated in four of nine studies. CONCLUSIONS: Opioid use for patients undergoing donor hepatectomy is likely to impact both their short- and long-term outcomes. To reduce post-operative pain scores, shorten length of hospital stay, and promote earlier post-operative return of bowel function, we recommend that multi-modal analgesia be offered to patients undergoing living donor hepatectomy. Further research is required to confirm which multi-modal techniques are most associated with enhanced recovery in living liver donors.

Aldehyde dehydrogenase expression may be a prognostic biomarker and associated with liver cirrhosis in patients resected for hepatocellular carcinoma.

BACKGROUND: Several members of the aldehyde dehydrogenase (ALDH) isoenzyme family have been suggested as prognostic biomarkers in patients with hepatocellular carcinoma (HCC). The aim of the study was to evaluate overall ALDH family member expression by RNA sequencing and hierarchical clustering in tumor and adjacent liver tissue to predict survival and evaluate correlation with liver cirrhosis in patients undergoing liver resection for HCC. METHODS: We included patients having undergone liver resection for HCC between May 2014 and January 2018 at a tertiary referral university hospital (Copenhagen University Hospital, Rigshospitalet, Denmark). ALDH family member expression was evaluated by RNA sequencing of tumor and non-tumor liver tissue. Hierarchical clustering of ALDH genes was used to identify patient groups and correlations were established with overall survival, recurrence and histological features. RESULTS: Fifty-two patients were included with 88.5% males, 84.6% with only one HCC and 73.1% with a non-cirrhotic background liver. Median follow-up was 45.7 months. Patients in one cluster defined by its ALDH expression in the tumor tissue showed significantly worse overall survival (log-rank p = 0.015), also when adjusted for age, cirrhosis, microvascular invasion, resection margins and tumor number (hazard ratio 4.2, 95% confidence interval (CI) 1.5-11.9, p = 0.007). When evaluated individually, the isoenzyme ALDH1L1 may be of particular importance. Several clusters in non-tumor tissue were correlated with cirrhosis. Especially one cluster had a high discriminative ability (area under receiver operating characteristic curve of 0.839) and remained significantly associated with cirrhosis when corrected for age, microvascular invasion, resection margins and tumor number (odds ratio 44.2, 95% CI 5.5-352.0, p < 0.001). The combination of ALDH and a previously identified candidate biomarker (expression signature of the transcriptional targets of the peroxisome proliferator-activated receptors (PPARs)) may add additional prognostic value. CONCLUSION: The expression of ALDH family members in HCC was correlated with overall survival. Moreover, ALDH expression in non-tumor liver tissue was correlated with cirrhosis. Members of the ALDH family of enzymes may serve as a prognostic biomarker as well as potential targets for systemic treatment.

Morbidity and mortality after liver surgery for colorectal liver metastases: a cohort study in a high-volume fast-track programme.

BACKGROUND: For colorectal liver metastases, surgery is a high-risk procedure due to perioperative morbidity. The objective was to assess severity of complications after fast-track liver surgery for colorectal liver metastases and their impact on morbidity and mortality. METHODS: All patients were treated according to the same fast-track programme. Complications were graded according to the Clavien-Dindo classification for patients undergoing surgery from 2013 to 2015. Correlation between complications and length of stay was analysed by multivariate linear regression. RESULTS: 564 patient cases were included of which three patients died within 3 months (0.53%, 95% CI: 0.17-1.64%). Complications were common with Grade ≤ 2 in 167 patients (30%) and ≥ Grade 3a in 93 (16%). Patients without complications had a mean length of stay of 4.1 days, which increased with complications: 1.4 days (95% CI: 1.3-1.5) for Grade 2, 1.7 days (1.5-2.0) for Grade 3a, 2.3 days (1.7-3.0) for Grade 3b, 2.6 days (1.6-4.2) for Grade 4a, and 2.9 days (2.8-3.1) for Grade 4b. Following were associated with increased length of stay: complication severity grade, liver insufficiency, ascites, biliary, cardiopulmonary, and infectious complications. CONCLUSIONS: Complications after liver surgery for colorectal liver metastases, in a fast track setting, were associated with low mortality, and even severe complications only prolonged length of stay to a minor degree.

A case of thrombocytopenia and multiple thromboses after vaccination with ChAdOx1 nCoV-19 against SARS-CoV-2.

Recently, reports of severe thromboses, thrombocytopenia, and hemorrhage in persons vaccinated with the chimpanzee adenovirus-vectored vaccine (ChAdOx1 nCoV-19, AZD1222, Vaxzevria; Oxford/AstraZeneca) against severe acute respiratory syndrome coronavirus 2 have emerged. We describe an otherwise healthy 30-year-old woman who developed thrombocytopenia, ecchymosis, portal vein thrombosis, and cerebral venous sinus thrombosis the second week after she received the ChAdOx1 nCoV-19 vaccine. Extensive diagnostic workup for thrombosis predispositions showed heterozygosity for the prothrombin mutation, but no evidence of myeloproliferative neoplasia or infectious or autoimmune diseases. Her only temporary risk factor was long-term use of oral contraceptive pills (OCPs). Although both the prothrombin mutation and use of OCPs predispose to portal and cerebral vein thrombosis, the occurrence of multiple thromboses within a short time and the associated pattern of thrombocytopenia and consumption coagulopathy are highly unusual. A maximum 4T heparin-induced thrombocytopenia (HIT) score and a positive immunoassay for anti-platelet factor 4/heparin antibodies identified autoimmune HIT as a potential pathogenic mechanism. Although causality has not been established, our case emphasizes the importance of clinical awareness. Further studies of this potentially new clinical entity have suggested that it should be regarded as a vaccine-induced immune thrombotic thrombocytopenia.

The psychological symptom burden in partners of pancreatic cancer patients: a population-based cohort study.

PURPOSE: Pancreatic cancer (PC) has high morbidity and mortality and is stressful for patients and their partners. We investigated the psychological symptom burden in partners of PC patients. METHODS: We followed 5774 partners of PC patients diagnosed from 2000 to 2016 up for first redeemed prescriptions of antidepressants or hospital admission, anxiolytics, and hypnotics as proxies for clinical depression, anxiety, and insomnia and compared them with 59,099 partners of cancer-free spouses. Data were analysed using Cox regression and multistate Markov models. RESULTS: The cumulative incidence proportion of first depression was higher in partners of PC patients compared to comparisons. The highest adjusted HR of first depression was seen the first year after diagnosis (HR 3.2 (95% CI: 2.9; 3.7)). Educational level, chronic morbidity, and bereavement status were associated with an increased risk of first depression. There was a significantly higher first acute use (1 prescription only) of both anxiolytics and hypnotics and chronic use (3+ prescriptions) of hypnotics in partners of PC patients than in comparisons. CONCLUSION: Being a partner to a PC patient carries a substantial psychological symptom burden and increases the risk for first depression and anxiolytic use and long-term use of hypnotics. Attention should be given to the psychological symptom burden of partners of PC patients, as this may pose a barrier for the optimal informal care and support of the PC patient, as well as a risk for non-optimal management of symptoms in the partner.

Phrenic nerve block on severe post-hepatectomy shoulder pain: A randomized, double-blind, placebo-controlled, pilot study.

BACKGROUND: Severe shoulder pain occurs frequently after surgery close to the diaphragm, potentially caused by referred pain via the ipsilateral phrenic nerve. We aimed to assess the analgesic effect of an ultrasound-guided phrenic nerve block on moderate to severe right-sided shoulder pain after open partial hepatectomy. METHODS: This was a randomized, double-blind, placebo-controlled, pilot study, comparing ultrasound-guided phrenic nerve block (ropivacaine 0.75 mg/mL) versus placebo (isotonic sodium chloride 0.9 mg/mL) on severe post-hepatectomy shoulder pain (NRS ≥6). Pre- and postoperative spirometry and arterial blood gas analyses were used to assess respiratory function. Subjects with chronic lung disease were excluded. Unfortunately, due to lack of funding, the trial was ended prematurely and therefore presented as a pilot study. RESULTS: One hundred and one subjects were screened for eligibility; 14 subjects were randomized, and two subjects were later excluded; thus, 12 subjects were analyzed with six in each group. A statistically significant difference in reduction in median pain intensity between groups was observed 15 minutes after phrenic nerve block ("ropivacaine first" ΔNRS: -6.0 [-6.0 to -3.0] vs. "saline first" ΔNRS: 0 [-6.0 to 1.0], P = .026). Spirometry results and arterial blood gas analyses were not clinically impacted by the block. CONCLUSIONS: Postoperative phrenic nerve block significantly reduced severe post-hepatectomy shoulder pain. Larger studies are warranted to confirm the lack of clinically relevant block-related impairment of respiratory function.
