High expression of CD8+ T-lymphocytes in the peritumoral zone of renal cancer as a factor of unfavorable prognosis

AIM: To evaluate the prognostic value of quantitative CD8+ T-lymphocyte counts in the peritumorotic zone of renal cell cancer.
 MATERIAL AND METHODS: The material of 74 patients after operative treatment for renal cell carcinoma with complete 5-year follow-up was retrospectively analyzed. Of the 74 patients, 56 were alive by the 5-year follow-up, and 18 had died of cancer. After immunohistochemical staining, CD8+ T-lymphocyte distribution density in the peritumorotic zone of carcinomas was determined in 3 representative fields of view at 400 magnification and correlated with the clinicopathological characteristics of neoplasms and overall 5-year patient survival rate.
 RESULTS: The high level of CD8+ T-lymphocyte infiltration in the peritumoral zone of carcinomas was seen in stages IIIIV of the disease (p=0.0000001), in tumors 7 cm (p=0.0000001), in Fuhrman grade IIIIV anaplasia (p=0.001), in metastases (p=0.0000001) and in the shorter total survival rate of patients (p=0.0003). High CD8+ T-lymphocyte count was also observed in men (p=0.001) and in cases of unclassified cancer.
 CONCLUSION: In the light of the need to search for new prognostic criteria in renal cancer, we conclude that a high level of peritumorous zone infiltration by CD8+ T-lymphocytes is an unfavorable prognostic factor. Assessment of peritumorous zone infiltration by CD8+ T-lymphocytes may serve as an additional prognostic factor in renal cell carcinoma.

Impact of anastomotic leakage on survival after surgery for gastric carcinoma: A PRISMA systematic review and meta-analysis.

The long-term survival of postoperative anastomotic leakage (AL) following gastric cancer (GC) surgery is still debating. Our aim was to investigate the association between AL and survival of the patients following GC. We searched articles in databases from inception to July 2023 to retrieve literature related to postoperative AL and survival of GC patients. We evaluated the association of postoperative AL and survival of GC patients using the software STAT10.0. Seven articles with 6209 GC patients were included. Our results showed that the postoperative AL were associated with pooled 1-year patient overall survival (OS) result in an odds ratio (OR) of 0.504 (95% confidence interval (CI): 0.372-0.682; I2 = 84.1%; P = .000), pooled 3-year patient OS (OR = 0.467, 95% CI: 0.356-0.614; I2 = 85.3%; P = .000) and pooled 5-year patient OS (OR = 0.370, 95% CI: 0.171-0.805; I2 = 82.5%; P = .012). The P value of Egger test were 0.759, 0.187, 0.175. The postoperative AL were associated with pooled 1-year patient disease-free survival (DFS) result in an OR of 0.538 (95% CI: 0.171-1.691; I2 = 89.0%; P = .289), the pooled 3-year patient DFS (OR = 0.143, 95% CI: 0.119-1.431; I2 = 91.7%; P = .163), and the pooled 5-year patient DFS (OR = 0.344, 95% CI: 0.088-1.338; I2 = 91.0%; P = .124), and the P value of Egger test of pooled 1-, 3-, and 5-year DFS were 0.759, 0.247, 0.07. Postoperative AL was correlated with a worse OS in GC patients, but not correlated with DFS in GC patients, but more studies are required to confirm this conclusion.

What Are the Complication Rates and Factors Associated With Total Femur Replacement After Tumor Resection? Findings From the Japanese Musculoskeletal Oncology Group.

Patients undergoing massive tumor resection and total femur replacement (TFR) face a substantial risk of hip dislocation and infection, often resulting in multiple implant revisions or hip disarticulation. These complications can impact their independence and prognosis. Additionally, their shorter life expectancy is influenced by challenges in achieving local radical resection and controlling metastases. Identifying suitable candidates for TFR is vital, necessitating investigations into dislocation, infection, implant failure rates, local recurrence, overall survival, and associated factors. (1) What is the postsurgical complication (hip dislocation and infection) rate and factors associated with postsurgical complications in patients who underwent TFR after tumor resection? (2) What is the local recurrence rate, implant failure rate, overall survival rate, and factors associated with local recurrence and implant failure? We retrospectively evaluated 42 patients (median [range] age 47 years [10 to 79 years]) who underwent TFR and tumor resection at the time of the same surgical procedure between 1990 and 2020 at 12 registered institutions that specialized in tumor treatment in Japan. A total of 55% (23) of the patients were men, and 79% (33) had bone sarcoma. The median (range) follow-up period was 36.5 months (2 to 327 months). Of the 42 patients, 12% (5) were lost to follow-up before 2 years without meeting a study endpoint (postsurgical complications, revision, or amputation), and another 19% (8) died before 2 years with implants intact, leaving 69% (29) of the original group who had either follow-up of at least 2 years or met a study endpoint before the minimum surveillance duration. Another 10% (4) had a minimum of 2 years of follow-up but had not been seen in the past 5 years. Infection was defined as deep-seated infection involving soft tissues, bones, joints, and the area around the implant. We did not consider superficial infections. Implant failure was defined when a patient underwent reimplantation or amputation. The complication and implant failure rates were assessed by the cumulative incidence function method, considering competing events. The Kaplan-Meier method was used to estimate the overall survival rate. The 1-month, 6-month, 1-year, and 2-year dislocation rates were 5%, 12%, 14%, and 14%, respectively. The 1-month, 6-month, 1-year, and 2-year infection rates were 5%, 7%, 10%, and 15%, respectively. Multivariable analyses for hip dislocation and infection revealed that resection of the abductor muscles and large tumor size were positively associated with hip dislocation. The 6-month, 1-year, and 2-year local recurrence rates were 5%, 15%, and 15%, respectively. The 6-month, 1-year, 2-year, and 5-year implant failure rates were 5% (95% confidence interval 1% to 15%), 7% (95% CI 2% to 18%), 16% (95% CI 6% to 29%), and 16% (95% CI 6% to 29%), respectively. Multivariable analyses of local recurrence and implant failure that led to reimplantation or amputation revealed that a positive surgical margin was positively associated with local recurrence. The 1-year, 2-year, and 5-year overall patient survival rates were 95% (95% CI 87% to 102%), 77% (95% CI 64% to 91%), and 64% (95% CI 48% to 81%), respectively. Hip dislocation, infection, and local recurrence were frequently observed in patients who received massive tumor resection and TFR in our study, eventually leading to reimplantation or amputation. Preserving the abductor muscles and resecting the tumor with a wide margin can prevent postoperative dislocation and local recurrence. Future research should focus on patient selection criteria, prevention of hip dislocation, and innovative treatments. Level IV, therapeutic study.

Management and outcomes after liver transplantation for progressive familial intrahepatic cholestasis: A systematic review and meta-analysis.

Progressive familial intrahepatic cholestasis (PFIC) is a heterogeneous rare congenital cholestatic liver disease. Disease progression might necessitate liver transplantation (LT). The aim of this study was to describe the outcome of PFIC1-4 patients after LT. Electronic databases were searched to identify studies on PFIC and LT. Patients were categorized according to PFIC type, genotype, graft type, age at LT, time of follow-up, and complications and treatment during follow-up. Seventy-nine studies with 507 patients met inclusion criteria; most patients were classified as PFIC1-3. The median age at LT was 50 months. The overall 5-year patient survival was 98.5%. PFIC1 patients with diarrhea after LT were at significant risk of developing graft steatosis ( p < 0.0001). Meta-analysis showed an efficacy of 100% [95% CI: 73.9%-100%] for surgical biliary diversion to ameliorate steatosis and 94.9% [95% CI: 53.7%-100%] to improve diarrhea (n = 8). PFIC2 patients with bile salt export pump (BSEP)2 or BSEP3-genotype were at significant risk of developing antibody-induced BSEP deficiency (AIBD) ( p < 0.0001), which was reported in 16.2% of patients at a median of 36.5 months after LT. Meta-analysis showed an efficacy of 81.1% [95% CI: 47.5%-100%] for rituximab-based treatment regimens to improve AIBD (n = 18). HCC was detected in 3.6% of PFIC2 and 13.8% of PFIC4 patients at LT. Fifty percent of PFIC1 patients develop diarrhea and steatosis after LT. Biliary diversion can protect the graft from injury. PFIC2 patients with BSEP2 and BSEP3 genotypes are at significant risk of developing AIBD, and rituximab-based treatment regimens effectively improve AIBD. PFIC3 patients have no PFIC-specific complications following LT.

Patient Reported Outcomes Following Open Broström-Gould Procedure: Minimum 5 Year Follow Up

Category: Hindfoot; Sports Introduction/Purpose: The purpose of this study is to demonstrate five-year patient-reported outcomes following the Broström- Gould procedure for the treatment of CAI in the general population. This is the first study utilizing PROMIS and FAAM scores at a minimum followup of five years and will provide valuable insight into the long term efficacy of the BG procedure. Additionally, our regression analysis portrays information on which individual patient factors independently influence patient reported outcome scores. Methods: Following approval from our institution’s IRB, the electronic medical record was queried for CPT code 27698 (Broström-Gould) from Jan 2010 to June 2017. Patients were included if they had a preoperative diagnosis of chronic lateral ankle instability and failed nonoperative management. Patients were excluded if they had undergone any surgeries since their BG repair (except revision BG repair), had a follow up of less than five years, were under the age of 18, or declined to answer all PROMIS and FAAM surveys. Surveys were conducted in the clinic and through phone interviews. Utilizing the EMR, patient charts were reviewed to obtain basic patient demographic information including sex, age, race, and body mass index (BMI). Comorbidities including, but not limited to, tobacco use, diabetes, hypothyroidism, rheumatoid arthritis were also recorded. Results: Our results show that the minimum 5-year patient reported PROMIS scores for patient’s following a Brostrom-Gould procedure are as follows: PROMIS PF - 50.5, PROMIS PI, 48.2, and PROMIS D - 38 2. This indicates, at a minimum, that patients 5-years removed from the procedure are within one standard deviation of the general population in regards to PROMIS physical function and pain. Our patient reported FAAM, ADL, and FAAM S scores were 59.6 and 13.0 respectively. Conclusion: This study is the first paper to report minimum five year patient reported PROMIS scores following the Broström- Gould procedure. We believe it is a valuable contribution to the literature as it provides both the treating surgeon and patient with evidence that the BG is a safe and effective procedure at the 5-year mark. Additionally, we have isolated potential factors that independently correlate with PROMIS outcomes including tobacco use, diabetes, and sports participation. We have shown the efficacy of the BG at 5-years and have provided the framework for future comparison studies hoping to utilize the PROMIS system to assess outcomes.

Comparable Outcomes of Cartiva Implant, Cheilectomy, and Fusion for Hallux Rigidus of the 1st Metatarsophalangeal Joint: A Matched Cohort Study

Category: Midfoot/Forefoot; Other Introduction/Purpose: The primary goal of treating hallux rigidus of the 1st metatarsophalangeal (MTP) joint of the foot is to reduce pain. Treatment options include cheilectomy, interposition arthroplasty, and arthrodesis for more severe disease. Recently, the use of a synthetic cartilage implant (Cartiva, Stryker Inc., MI, USA) has been introduced with the advantage of motion preservation. While a Level 1 study has demonstrated similar outcomes of fusion and Cartiva, other comparative studies have shown less favorable results for the Cartiva implant. The purpose of this study was to evaluate minimum 2-year patient reported outcomes (PROs) of the Cartiva implant for the treatment of hallux rigidus in the 1st MTP joint in comparison to a matched cohort of patients treated with fusion or cheilectomy. Methods: Patients &gt;18 years old who underwent surgery for treatment of 1st MTP joint hallux rigidus with Cartiva implant, cheilectomy, or fusion performed by two surgeons (T.O.C. or C.T.H.) between January 2009 and January 2020 were identified. A 2:1 matched control cohort of patients who underwent cheilectomy or fusion was constructed using a nearest neighbor, greedy algorithm based on age, sex, prior surgery, and Coughlin osteoarthritis grade. Minimum 2-year follow-up was obtained with patients completing subjective questionnaires including Foot and Ankle Ability Measure (FAAM) with Activities of Daily Living (ADL) and Sport subscales, Short Form-12 (SF-12), Tegner activity scale, and patient satisfaction with surgical outcome. Demographics and patient-reported outcomes were compared between groups. Results: Follow-up was obtained for 22/27 (82%) Cartiva patients (mean age 54±19) at median 4.3 years and 41/49 (84%) control patients (mean age 58±11) at median 3.5 years. Prevalence of Coughlin grade was similar between Cartiva and control groups (6 vs 10 grade 1, 8 vs 15 grade 2, 2 vs 6 grade 4, 6 vs 10 grade 5; p=.93), respectively. There was no significant difference in median post-operative FAAM-ADL (96 vs 95, p=.53), FAAM-Sport (92 vs 89, p=.89), SF-12 PCS (56 vs 51, p=.054), SF-12 MCS (56.3 vs 57.5, p=.50), Tegner score (4 vs 3, p=.30), or patient satisfaction (9 vs 9, p=.91) between Cartiva and control cohorts, respectively. Revision surgery was required for 3 (14%) Cartiva patients and 4 (10%) control patients (p=.70). Conclusion: Patients treated with a Cartiva synthetic cartilage implant for 1st MTP joint hallux rigidus had similar patient-reported outcomes and revision rate compared to patients treated with cheilectomy or fusion for Coughlin grade 2-5 osteoarthritis.

Long Term Patient Reported Quality of Life Outcomes and Patient Satisfaction of 1-Week Hypofractionated Whole Breast Radiation Therapy Using IMRT for Early-Stage Breast Cancer

Novel whole breast radiation therapy (WBRT) regimens have been recently reported with the aim of improving patient convenience while preserving local control and breast cosmesis. The UK FAST Forward trial showed that 26 Gy in 5 fx using 3D conformal WBRT was equivalent to the standard 3-week regimen. However, the use of inverse planned intensity modulated radiation therapy (IMRT) for this novel ultra-hypofractionated regimen has not been previously studied. We aim to study the patient reported quality of life (QOL) outcomes and patient satisfaction of WBRT using IMRT delivering 26 Gy in 5 fractions. Patients receiving WBRT with 26 Gy in 5 fractions using IMRT at our institution from 2020 to 2022 were included. Patients were treated with 26 Gy in 5 daily fx with or without a single fx boost of 4-5.2 Gy. IMRT plans were generated using inverse planning with 2 to 3 volumetric modulated arcs (VMAT). To assess patient-reported QOL outcomes, a questionnaire was prospectively administered at 1 month post treatment and yearly thereafter including the EORTC QLQ-BR23 breast cancer module and other patient satisfaction questions. Patient assessment involved a four-point scale (not at all, a little, quite a bit, and very much; very satisfied, moderately satisfied, moderately dissatisfied, and very dissatisfied). Here, we report the 1-year patient reported acute toxicity QOL outcomes and patient satisfaction for those undergoing IMRT based WBRT. Cross-sectional analyses were used to determine the prevalence of "quite a bit" or "very much" effects versus "not at all" or "a little" effects. A total of 96 patients were included. The median age at diagnosis was 65 years. The most common histology was invasive ductal carcinoma (53.1%). ER-positivity was found in 75.5% patients. Oncoplastic reconstruction was used in 51.0% patients. The median tumor size was 1.5 cm. There were 4/98 (4.3%) node positive patients and 22.5% received adjuvant chemotherapy. Endocrine therapy was used in 74.5% patients. A boost fraction was delivered in 95.9% patients. At the 1-year assessment, only 1/35 (2.9%), 2/35 (5.7%), and 4/35 (11.4%) patients reported "quite a bit" or "very much" breast pain, skin problems, and changes in breast appearance respectively. Additionally, 32/35 (91.4%) patients were either "very satisfied" or "moderately satisfied" with their treatment, while 32/35 (91.4%) patients reported "excellent" (n = 12) or "good" (n = 20) physical appearance of the breast. WBRT using inverse planned IMRT with 26 Gy in 5 fx shows excellent patient reported QOL and patient satisfaction at 1-year post RT. Longer follow up is needed to assess the long-term toxicity, normal tissue effects, and cosmetic outcomes of IMRT based delivery of this ultra-hypofractionated regimen.

Multi-Institutional Phase II Trial Using Dose Escalated Five Fraction Stereotactic Partial Breast Irradiation (S-PBI) with GammaPodTM for Early-Stage Breast Cancer

We report on our early experience of a multi-institutional phase II study of dose escalated five fraction stereotactic partial breast irradiation (S-PBI) for early-stage breast cancer after partial mastectomy using the GammaPodTM stereotactic radiation system. Patient eligibility included DCIS or invasive epithelial histologies, AJCC clinical stage 0, I, or II with tumor size < 3 cm, and negative margins. Prior safety of Phase I dose escalation has been reported. Dose was 40 Gy delivered in 5 fractions to the CTV, and minimum dose 30 Gy in 5 fractions to the PTV. CTV margin was 1 cm and PTV margin 3 mm. For PTV cavities larger than 100cc, dose was reduced to 35Gy in 5 fractions to the CTV and 30 Gy in 5 fractions to the PTV. Primary endpoint of the study is to determine the 3-year patient global cosmesis score (4-point scale excellent, good, fair, or poor) and adverse cosmesis using a dose escalated approach with smaller PTV margins than conventional methods. Both patients and physicians completed baseline and subsequent cosmesis outcome questionnaires. Treatment related toxicity was graded using the NCI version 4.0 and RTOG/EORTC late radiation scale. From 3/2019-10/2021, 74 patients were treated respectively. Of these, 38 were treated to 40Gy and 36 were treated to 35 Gy. Median follow up (f/u) was 24 months (mo), range (r) 3-39mo. Median age was 63 years (r 43-77). Histology included 28 DCIS, and 46 invasive carcinomas. 45/46 invasive tumors were ER+. 60/74 (81%) patients received endocrine therapy, and 7/74 patient received chemotherapy. There were 221 acute grade 1 toxicities, and 28 Grade 2 toxicities. No grade 3 or higher acute toxicities were reported (< 90 days). The most common Grade 2 toxicities were radiation dermatitis (10), breast pain (8), blister (4), skin infection (2), nipple discharge (2), and fatigue (2). In the late period, there were 54 Grade 1 late toxicities, 4 Grade 2 late toxicities, and no Grade 3 or higher late toxicities. Grade 2 toxicities included fibrosis (2), and pain (2). Two patients developed grade 1 asymptomatic nonpalpable fat necrosis both diagnosed at 12 months after radiation treatments. The most common grade 1 late toxicities were breast pain (14), hyperpigmentation (8), fibrosis (10), and fatigue (5). Physicians scored cosmesis excellent or good 70/73 (95.8%), 58/60 (96.7%), 36/36 (100%),17/17(100%) respectively at baseline, 12 months, 24 months, and 36months post SBRT, while patients scored the same periods 62/71 (83.7%), 53/59 (89.8%), 33/36 (91.6%), 17/18 (94.4%). There have been no reports of disease recurrences. Results at 24-month median follow-up, of our dose escalated stereotactic partial breast 5 fraction regimen, has low acute and late toxicity, while maintaining high proportion of excellent/good cosmetic outcomes. Continued analysis of all cohorts is in progress. gov identifier is NCT03581136.

Restoration of the sagittal profile according to the Roussouly classification reduces mechanical complications and revision surgery in older patients undergoing surgery for adult spinal deformity (ASD).

The mechanical complications related to ASD remain a concern due to their morbidity and associated revision surgery. Restoration of each patient's Roussouly profile may reduce these. Our aim was to examine if the restoration of the Roussouly profile reduced these complications and revision rates in older patients operated for degenerative ASD. Retrospective analysis of a single-centre, 2-year minimum follow-up patient database. All patients undergoing corrective surgery (≥ 4 levels) for ASD were included with analysis of demographic data, operative records, restoration of Roussouly sagittal profile, mechanical complications and revision rates. Univariate and multivariate analysis was conducted. Fifty-two patients were included (mean age was 72.3years, average follow-up 56.3months). Twenty-six patients had a "restored" profile (50%) and 26 an "unrestored" profile (50%). The incidence of mechanical complications was 7 (27%) and 23 (88%) for the restored and unrestored groups, respectively (p < 0.001). Revision rates were 4 (15.4%) and 18 (69.2%), respectively (p < 0.000), in the restored and unrestored profiles. Univariate analysis determined that profile restoration and BMI were associated with mechanical complications and revision surgery, whilst only the profile restoration status maintained its statistical power in multivariate analysis (p = 0.002 and p = 0.002, respectively). Age was not a significant factor in univariate analysis. The relative risk for mechanical failure and revision surgery was 5.6 times (CI 1.929-16.39) and 3.08 times (CI 1.642-5.734) greater if the profile was not restored. Achieving each patient's ideal Roussouly profile is associated with a reduced incidence of mechanical complications and revision rates in the older population after surgery for degenerative ASD.

Recurrence of follicular dendritic cell sarcoma in tonsils after 7 years: a rare case report

Follicular dendritic cell sarcoma (FDCS) is a rare mesenchymal neoplasm. It arises from not only from lymph nodes but also from extra nodal tissues, either as acquired lymphoid tissue or as part of the organized constitutive lymphoid tissue. We here report this rare entity which developed again after 7 years post tonsillectomy in a 5-year old male patient. Patient underwent radical tonsillectomy and adjuvant treatment is awaited. Differential diagnosis includes large cell lymphoma, peripheral nerve sheath tumor, extracranial meningioma, malignant melanoma, metastatic carcinoma, ectopic thymoma, malignant fibrous histiocytoma, and interstitial reticulum cell sarcoma. Currently, the management of FDCS includes the therapeutic guidelines similar to that of high-grade soft tissue sarcomas that is complete surgical resection of the lesion with possibility of adjuvant radiotherapy and/or chemotherapy. The ideal combination of management of FDCS has yet to be defined.

Epidemiology and Risk Factors for Invasive Fungal Infections in Pancreas Transplant in the Absence of Postoperative Antifungal Prophylaxis

Abstract Background Invasive fungal infections (IFIs) remain a rare yet dreaded complication following pancreas transplantation. Current guidelines recommend antifungal prophylaxis in patients with 1 or more risk factors. At our center, single-dose antifungal prophylaxis is administered in the operating room but none subsequently, regardless of risk factors. Here we evaluate the 1-year incidence, outcome, and risk factors associated with IFI following pancreas transplantation. Methods A retrospective, single-center cohort study was conducted in patients who underwent pancreas transplantation between 1 January 2009 and 31 December 2019. Records were manually reviewed, and cases were adjudicated using consensus definitions. The 1-year cumulative incidence, mortality, and risk factors were analyzed by Kaplan-Meier method and differences between populations were assessed with Fisher test and Mann-Whitney U test. Results Three hundred sixty-nine recipients were included. Twelve IFIs were identified: candidiasis (8), aspergillosis (2), histoplasmosis (1), and cryptococcosis (1). Intra-abdominal infections were the most common presentation (5), followed by bloodstream infections (3), disseminated disease (2), pulmonary disease (1), and invasive fungal sinusitis (1). Median time to IFI was 64 days (interquartile range, 30–234 days). One-year cumulative incidence was 3.25% (95% confidence interval, 1.86%–5.65%). There were no significant differences between patients with or without IFI regarding type of transplant (P = .17), posttransplant dialysis (P = .3), rejection (P = .5), cytomegalovirus serostatus (P = .45), or reoperation (P = .19). For patients with IFI, the 1-year graft and patient survival rates were 58% versus 95% (P &amp;lt; .0001) and 75% versus 98.6% (P &amp;lt; .001), respectively. Conclusions Our study suggests that the use of a single-dose antifungal prophylaxis administered in the operating room but none subsequently does not result in an increased incidence of IFI following pancreas transplantation.

Cyclosporine vs. tacrolimus after liver transplantation for primary sclerosing cholangitis – a propensity score-matched intention-to-treat analysis

There is controversy regarding the optimal calcineurin inhibitor type after liver transplant(ation) (LT) for primary sclerosing cholangitis (PSC). We compared tacrolimus with cyclosporine in a propensity score-matched intention-to-treat analysis based on registries representing nearly all LTs in Europe and the US. From the European Liver Transplant Registry (ELTR) and Scientific Registry of Transplant Recipients (SRTR), we included adult patients with PSC undergoing a primary LT between 2000-2020. Patients initially treated with cyclosporine were propensity score-matched 1:3 with those initially treated with tacrolimus. The primary outcomes were patient and graft survival rates. The propensity score-matched sample comprised 399 cyclosporine-treated and 1,197 tacrolimus-treated patients with PSC. During a median follow-up of 7.4 years (IQR 2.3-12.8, 12,579.2 person-years), there were 480 deaths and 231 re-LTs. The initial tacrolimus treatment was superior to cyclosporine in terms of patient and graft survival, with 10-year patient survival estimates of 72.8% for tacrolimus and 65.2% for cyclosporine (p <0.001) and 10-year graft survival estimates of 62.4% and 53.8% (p <0.001), respectively. These findings were consistent in the subgroups according to age, sex, registry (ELTR vs. SRTR), time period of LT, MELD score, and diabetes status. The acute rejection rates were similar between groups. In the multivariable Cox regression analysis, tacrolimus (hazard ratio 0.72, p <0.001) and mycophenolate use (hazard ratio 0.82, p= 0.03) were associated with a reduced risk of graft loss or death, whereas steroid use was not significant. Tacrolimus is associated with better patient and graft survival rates than cyclosporine and should be the standard calcineurin inhibitor used after LT for patients with PSC. The optimal calcineurin inhibitor to use after liver transplantation in patients with primary sclerosing cholangitis has yet to be firmly established. Since randomized trials with long follow-up are unlikely to be performed, multicontinental long-term registry data are essential in informing clinical practices. Our study supports the practice of using tacrolimus instead of cyclosporine in the initial immunosuppressive regimen after liver transplantation for patients with primary sclerosing cholangitis. The retrospective registry-based design is a limitation.

Outcomes of pediatric liver transplantation for progressive familial intrahepatic cholestasis.

Progressive familial intrahepatic cholestasis (PFIC) is a heterogenous group of inherited hepatocellular disorders and the clinical aspects, role of liver transplantation (LT), and its outcomes remain largely unelucidated. We present our data of LT for each type of PFIC and compare their early, and long-term outcomes, highlighting their individual differences and management strategies. Prospectively collected data over a decade (2011-2022) of children with PFIC who underwent LT was analyzed. The groups (PFIC 1-4) were compared with regard to early and long-term outcomes including attainment of catch-up growth. Of 60 children with PFIC who underwent LT, 13, 11, 31 & 5 were of PFIC 1, 2, 3 & 4, respectively. There were no significant differences in gender, PELD scores, BMI, type of grafts, cold and warm ischemia times, intraoperative blood loss, and morbidity among the groups. Post-LT chronic diarrhea was observed in 6 (46.1%) children with PFIC-I, and of them, 3 (23%) developed graft steatohepatitis. Three of these children underwent total internal biliary diversion (TIBD) and on 1-year follow-up, their graft steatosis resolved and they attained catch-up growth. Catch-up growth was significantly poorer in the PFIC1 group (44.4% vs. 88%, 90%, 100% p < .001). Overall 1- and 5-year patient survival of the four PFIC groups (1-4) were 69.2%, 81.8%, 96.8%, 100% & 69.2%, 81.8%, 96.8%, 100%, respectively. Ours is the largest to-date series of LT for PFIC illustrating their short- and long-term outcomes. While the results for the whole cohort were excellent, those after LT for PFIC1 was relatively poorer as reflected by catch-up growth, graft steatosis, and post-LT diarrhea, which can be optimized by the addition of TIBD during LT.

Nodular regenerative hyperplasia and liver transplantation: a systematic review.

Nodular regenerative hyperplasia (NRH) is a primary disease of the liver that may cause noncirrhotic portal hypertension. Common causes include autoimmune, hematologic, immune deficiency, and myeloproliferative disorders. Given the limited data regarding the development of NRH in contemporary immunosuppressive protocols and the occurrence of NRH post-liver transplantation, we systematically reviewed NRH as it pertains to liver transplantation. We performed a comprehensive search for NRH and transplantation. Nineteen studies were identified with relevant data for NRH as an indication for a liver transplant. Thirteen studies were identified with relevant data pertaining to NRH development after liver transplant. Pooled analysis revealed 0.9% of liver transplant recipients had NRH. A total of 113 patients identified with NRH underwent liver transplantation. Most series report transplants done after the failure of endoscopic banding and TIPS management of portal hypertension. Reported 5-year graft and patient survival ranged from 73%-78% and 73%-90%. The pooled incidence of NRH after liver transplant for all indications was 2.9% and caused complications of portal hypertension. Complications related to portal hypertension secondary to NRH are a rare indication for a liver transplant. NRH can develop at any time after liver transplantation often without an identifiable cause, which may lead to portal hypertension requiring treatment or even re-transplantation.

Sedating antihistamine treatment with promethazine in patients with severe COPD with and without asthma: death and severe exacerbations in a nationwide register study

ABSTRACT Background Sedating antihistamines such as promethazine are used as anxiolytics and hypnotic agents for patients with chronic obstructive pulmonary disease (COPD) with and without asthma despite limited knowledge of its effects and side effects. We evaluated if treatment with promethazine had a lower risk of harmful outcome. Methods Nationwide retrospective cohort study of Danish specialist diagnosed outpatients with COPD treated with promethazine or an active comparator (melatonin). Patients with collection of promethazine or melatonin were propensity score matched 1:1. The primary outcome was a composite of severe COPD exacerbations and death from all causes analyzed by Cox proportional hazards regression. We performed an interaction analysis for comorbid asthma. Results In our registry of 56,523 patients with COPD, 5,661 collected promethazine (n = 3,723) or melatonin (n = 1,938). A cohort of 3,290 promethazine- or melatonin-treated patients matched 1:1 was available for the primary analysis. Within 1-year patients treated with promethazine were at higher risk of the primary outcome than matched controls with a Hazard Ratio (HR) of 1.42 (CI 1.27–1.58, p < 0.0001). Similarly, the risk of death was higher for promethazine-treated patients (HR 1.53, CI 1.32–1.77, p < 0.0001). An interaction analysis for comorbid asthma showed no interaction between comorbid asthma and the likelihood of a primary outcome when collecting promethazine (p = 0.19). Adjusted Cox analysis on the entire population indicated a further increased risk with more promethazine (HR for primary outcome among patients collecting ≥ 400 promethazine tablets/year=2.15, CI 1.94–2.38, p<0.0001). Conclusions Promethazine-treated patients with COPD had a concerning excess risk of a composite outcome of severe exacerbations and death from all causes compared to melatonin.

Impact of Community Socioeconomic Distress on Survival Following Heart Transplantation.

The aim of this study was to assess the impact of community-level socioeconomic deprivation on survival outcomes following heart transplantation. Despite growing awareness of socioeconomic disparities in the US health care system, significant inequities in outcomes remain. While recent literature has increasingly considered the effects of structural socioeconomic deprivation, the impact of community socioeconomic distress on outcomes following heart transplantation has not yet been elucidated. All adult heart transplant recipients from 2004 to 2022 were ascertained from the Organ Procurement and Transplantation Network. Community socioeconomic distress was assessed using the previously validated Distressed Communities Index, a metric that represents education level, housing vacancies, unemployment, poverty rate, median household income, and business growth by zip code. Communities in the highest quintile were considered the Distressed cohort (others: Non-Distressed ). Outcomes were considered across 2 eras (2004-2018 and 2019-2022) to account for the 2018 UNOS Policy Change. Three- and 5-year patient and graft survival were assessed using Kaplan-Meier and Cox proportional hazards models. Of 36,777 heart transplants, 7450 (20%) were considered distressed . Following adjustment, distressed recipients demonstrated a greater hazard of 5-year mortality from 2004 to 2018 [hazard ratio (HR)=1.10, 95% confidence interval (CI): 1.03-1.18; P =0.005] and 3-year mortality from 2019 to 2022 (HR=1.29, 95% CI: 1.10-1.51; P =0.002), relative to nondistressed . Similarly, the distressed group was associated with increased hazard of graft failure at 5 years from 2004 to 2018 (HR=1.10, 95% CI: 1.03-1.18; P =0.003) and at 3 years from 2019 to 2022 (HR=1.31, 95% CI: 1.11-1.53; P =0.001). Community-level socioeconomic deprivation is linked with inferior patient and graft survival following heart transplantation. Future interventions are needed to address pervasive socioeconomic inequities in transplantation outcomes.

Right versus left fully robotic live donor nephrectomy and open kidney transplantation: Does the laterality of the donor kidney really matter?

ObjectiveRobotic-assisted live donor nephrectomy (LDN) is being gradually adopted across transplant centers. The left donor kidney is preferred over right due to anatomical factors and ease of procurement. We aimed to study donor and recipient outcomes after robotic procurement and subsequent open implantation of right and left kidneys. MethodsAll fully robotic LDNs and their corresponding open kidney transplants performed at our center between February 2016 and December 2021 were retrospectively analyzed. ResultsOut of 196 robotic LDN (49 [right] vs. 147 [left]), 10 (5.1%) donors had intra-operative events (6.1% [right] vs. 4.8% [left], p=0.71). None of the LDN required conversion to open surgery. The operative times were comparable for the two groups. Nausea (13.3%) was the most common post-operative complication. There was no mortality in either LDN group. Herein, we report our outcomes on 156 recipients (39 right and 117 left allografts) excluding robotic implants, exports, and pediatric recipients. There were no significant differences between right and left kidney recipients with respect to 1-year post-transplant patient survival (100.0% vs. 98.1%, p=0.45) or graft survival (93.9% vs. 97.1%, p=0.11), or delayed graft function (7.7% vs. 5.1%, p=0.55). ConclusionNon-hand-assisted robotic live donor nephrectomies can be safely performed with excellent outcomes. Right LDN was not associated with higher incidence of complications compared to left LDN. Open implantation of robotically procured right renal allografts was not associated with higher risk of recipient complications.

Integration of a Smartphone HF-Dedicated App in the Remote Monitoring of Heart Failure Patients with Cardiac Implantable Electronic Devices: Patient Access, Acceptance, and Adherence to Use.

To assess real-world HF patient access, acceptance, and adherence to use of an HF-dedicated smartphone application (HF app). In this study, 10 Italian hospitals administered a survey on smartphone/app use to HF patients with CIED. The subgroup who accepted it downloaded the HF app. Mean 1-year adherence of the HF app use was evaluated. A total of 495 patients (67 ± 13 years, 79% males, 26% NYHA III-IV) completed the survey, of which 84% had access to smartphones and 85% were willing to use the HF app. In total, 311/495 (63%) downloaded the HF app. Patients who downloaded the HF app were younger and had higher school qualification. Patients who were ≥60 years old had higher mean 1-year adherence (54.1%) than their younger counterparts (42.7%; p < 0.001). Hospitals with RM-dedicated staff had higher mean 1-year patient adherence (64.0% vs. 33.5%; p < 0.001). Adherence to HF app decreased from 63.3% (weeks_1-13) to 42.2% (weeks_40-52, p < 0.001). High access and acceptance of smartphones/apps by HF patients with CIED allow HF app use for RM of patient signs/symptoms. Younger patients with higher school qualifications are more likely to accept HF app; however, older patients have higher long-term adherence.

Predicting 5-year survival after kidney transplantation in Colombia using the survival benefit estimator tool.

A complex relationship between donor and recipient characteristics influences kidney transplant (KT) success. A tool developed by Bae S. et al. (Survival Benefit Estimator, SBE) helps estimate post-KT survival. We aim to evaluate the predictive performance of the SBE tool in terms of 5-year patient survival after a kidney transplant. A retrospective cohort study of all deceased-donor KT recipients between January 2009 to December 2021. A descriptive analysis of clinical and sociodemographic characteristics was performed. The SBE online tool was used to calculate the predicted patient survival (PPS) and the survival benefit at five years post-KT. Comparisons between predictive vs. actual patient survival were made using quintile subgroups. Three Cox regression models were built using PPS, EPTS, and KDPI. A total of 1145 recipients were evaluated. Mortality occurred in 157 patients. Patient survival was 86.2%. Predictive survival for patients if they remained on the waiting list was 70.6%. The PPS was 89.3%, which results in a survival benefit (SB) of 18.7% for our population. Actual survival rates were lower than the predicted ones across all the quintiles. In unadjusted analysis, PPS was a significant protective factor for mortality (HR 0.66), whereas EPTS (HR 8.9) and KDPI (HR 3.25) scores were significant risk factors. The discrimination of KDPI, PPS, and EPTS scores models were 0.59, 0.65, and 0.66, respectively. SBE score overestimated actual survival rates in our sample. The discrimination power of the score was moderate, although the utility of this tool may be limited in this specific population.

Survival after a heart attack with subsequent cardiac arrest: a 1-year patient case report

BackgroundCardiac events have become a common occurrence worldwide and especially in India, more so after the coronavirus disease (COVID) pandemic. Apparently healthy and young individuals suffering from cardiac disorders are on the rise. In most cases, there is no clearly established cause/risk factor for the cardiac disorder. Once someone has suffered a cardiac event, the rehabilitation team is expected to keep a constant watch on the prognosis and any complications that might arise, especially during the first year after the cardiac event.Case presentationThis case report describes the sequence of events that occurred in a 44-year-old male patient who had a heart attack, survived a cardiac arrest, was implanted with a cardioverter defibrillator (ICD), and was on rehabilitation. The report throws some insights into what happened with this patient since his heart attack, and it also discusses the possible signs that could have helped identify the cardiac event before the actual occurrence.ConclusionThe rehabilitation post heart attack, angioplasty, and cardiac implants have to be individualized and tailor-made. Appropriate alterations to the rehabilitation would give the necessary direction to achieve maximum recovery and well-being of the patient. Constantly watching for any complications that might arise and addressing them immediately are vital to the prognosis. Physiotherapy rehabilitation plays a major role in giving a positive reinforcement and better prognosis.
