[Efficacy analysis of surgical combined with postoperative adjuvant therapy for T3 gallbladder carcinoma: a multicenter retrospective study].

Objective: To explore the clinical value of adjuvant therapy in patients with T3 gallbladder cancer (GBC) who have undergone R0 resection. Methods: Clinical and pathological data from 415 patients with T3 GBC who underwent surgical treatment in 7 tertiary centers in China from January 2013 to December 2018 were collected,including 251 males and 164 females,aged (61±11)years (range: 26 to 88 years). Depending on whether to receive adjuvant therapy after radical resection,the patients were divided into the radical resection group alone (group A,n=358) and the radical resection combined with the postoperative adjuvant therapy group (group B,n=57). The general data of the two groups were matched 1∶1 by propensity score matching method,and the caliper value was 0.02.Clinicopathological characteristics,overall survival and disease-free survival of the two groups were compared.The Cox regression model was used for multivariate analysis,and patients with at least one or more independent risk factors were classified as high-risk clinicopathological subtypes. Subgroup analysis was performed to assess the clinical value of adjuvant therapy after radical resection in patients with high-risk clinicopathological subtypes. Results: After the matching,there were 42 patients in each of the two groups. The incidence of gallbladder cancer and the number of dissected lymph nodes in group B after cholecystectomy were higher than those in group A (χ2=9.224,2.570,both P<0.05). There were no significant differences in overall survival rate and disease-free survival rate between the two groups before and after matching (all P>0.05). The results of the univariate and multivariate analysis showed that CA19-9>39 U/ml,nerve invasion,tumor location (liver side or bilateral),TNM stage ⅢB to ⅣB ,poorly differentiated tumor were independent prognostic factors of overall survival and disease-free survival of patients with T3 stage gallbladder cancer (all P<0.05).Three hundred and twenty-nine patients(79.3%) had high-risk clinicopathological subtypes,and the median survival time after curative resection with and without adjuvant therapy was 17 months and 34 months respectively,and the 3-year and 5-year overall survival rates were respectively 40.0%,21.3% and 46.0%,46.0% (χ2=4.042,P=0.044);the median disease-free survival time was 9 months and 13 months,and the 3-year and 5-year disease-free survival rates were 23.4%,13.6% and 30.2%,18.2% (χ2=0.992,P=0.319). Conclusions: Postoperative adjuvant therapy following radical surgery did not yield significant improvements in the overall survival and disease-free survival rates of patients diagnosed with T3 gallbladder cancer. However, it demonstrated a significant extension in the overall survival rate for patients presenting high-risk clinicopathological subtypes.

[Clinical value of extended radical resection for pT3 stage gallbladder cancer].

Objective: To investigate the clinical value of extended radical resection for stage pT3 gallbladder cancer (GBC). Methods: The clinical and pathological data of 323 patients with stage pT3 GBC who received regional radical resection or extended radical resection in 7 domestic hepatobiliary centers in China from January 2013 to December 2018 were retrospectively analyzed. The propensity score matching method was used to select 36 cases in each of the regional radical resection group (group A1) and the extended radical resection group (group B1). The surgical indicators and overall survival rates of the two groups were compared, and prognostic factors were analyzed. Results: The number of positive lymph nodes [2(0,3)] and the total number of lymph nodes removed [3(1,4)] in group B1 were both higher than those in group A1 [1(0,1), 4(2,7)] (all P<0.05). There was no significant difference in other clinical and pathological factors between the two groups (all P>0.05). The 1, 3, and 5-year survival rates of group A1 were 75%, 44%, and 29%, respectively, which were significantly higher than those of group B1 of 50%, 15%, and 11% (χ(2)=11.311, all P<0.001). Extensive radical resection (HR=2.161, 95%CI: 1.222-3.821), hepatic parenchymal invasion (HR=2.324, 95%CI: 1.305-4.139), positive lymph node rate ≥1/3 (HR=2.927, 95%CI: 1.641-5.220), and ⅢB/ⅣB staging (HR=3.325, 95%CI: 1.750-6.320) are risk factors for the prognosis of GBC patients (all P<0.05), of which extended radical resection (HR=1.969, 95%CI: 1.083-3.581) was an independent risk factor for prognosis (P<0.05). When the ratio of positive lymph nodes was<1/3 and the tumor invaded the hepatic parenchyma, the overall survival rate of group B1 was significantly lower than that of group A1 (all P<0.05). Conclusions: The overall survival rate in patients with stage pT3 GBC whose lymph node positive rate<1/3 and/or hepatic parenchymal invaded cannot be improved by extended radical resection. Extended radical resection is an independent risk factor for patient prognosis.

[A multicenter clinical analysis of short-term efficacy of laparoscopic radical resection of hilar cholangiocarcinoma].

Objective: To investigate the feasibility and safety of laparoscopic radical resection of hilar cholangiocarcinoma at multiple centers in China. Methods: Between December 2015 and August 2019, the clinical data of 143 patients who underwent LRHC in Affiliated Hospital of North Sichuan Medical College, Second Hospital of Hebei Medical University, Affiliated Hospital of Xuzhou Medical University, Affiliated Tongji Hospital of Tongji Medical College, Huazhong University of Science and Technology, Hunan Provincial People's Hospital, the First Hospital Affiliated to Army Medical University, Sir Run Run Shaw Hospital Affiliated to Medical College of Zhejiang University, West China Hospital of Sichuan University, Nanfang Hospital of Southern Medical University and the First Affiliated Hospital of Chongqing Medical University were collected prospectively. There were 92 males and 51 females with age of (64±11) years (range: 53 to 72 years). Bismuth type: type I, 38 cases (26.6%), type Ⅱ, 19 cases (13.3%), type Ⅲa, 15 cases (10.5%), type Ⅲb, 28 cases (19.6%) and type Ⅳ, 43 cases (30.0%). The patients within the first 10 operation cases in each operation time (the first 10 patients in each operation team) were divided into group A (77 cases), and the patients after 10 cases in each operation time were classified as group B (66 cases); the cases with more than 10 cases in the center were further divided into group A(1) (116 cases), and the center with less than 10 cases was set as group A(2) (27 cases). T test or Wilcoxon test was used to compare the measurement data between groups, and the chi square test or Fisher exact probability method was used to compare the counting data between groups. Kaplan Meier curve was used for survival analysis. Results: All patients successfully completed laparoscopic procedure. The mean operation time was (421.3±153.4) minutes (range: 159 to 770 minutes), and the intraoperative blood loss was 100 to 1 500 ml (median was 300 ml) .Recent post-operative complications contained bile leakage, abdominal bleeding, abdominal infection, gastrointestinal bleeding, and delay gastric emptying, pulmonary infection, liver failure, et al.The post-operative hospital stay was (15.9±9.2) days. The operation time in group B was relatively reduced ( (429.5±190.7)minutes vs. (492.3±173.1)minutes, t=2.063, P=0.041) and the blood loss (465 ml vs. 200 ml) was also reduced (Z=2.021, P=0.043) than that in group B. The incidence of postoperative biliary fistula and lung infection in patients in group A was significantly higher than that in group B (χ(2)=4.341, 0.007; P=0.037, 0.047) .Compared with group A(2), the operation time in group A(1) was relatively reduced( (416.3±176.5)minutes vs. (498.1±190.4)minutes, t=2.136, P=0.034) , the incidence of bile leakage and abdominal cavity infection in group A(1) was lower than that in group A(2) (χ(2)=7.537, 3.162; P=0.006, 0.046) . Kaplan Meier survival curve showed that the difference of short-term survival time between group A and group B was statistically significant (P<0.05) . Conclusions: The completion of laparoscopic hilar cholangiocarcinoma radical surgery is based on improved surgical skills, and proficiency in standardized operation procedures.It is feasible for laparoscopic radical resection of hilar cholangiocarcinoma to well experienced surgeon with cases be strictly screened, but it is not recommended for widespread promotion at this exploratory stage.

GAD65 as a potential marker for cognitive performance in an adult population with prediabetes.

BACKGROUND: Diabetes mellitus (DM) is a well-known risk factor for cognitive dysfunction in aged populations. However, there are inconsistent reports about impaired fasting glucose or prediabetes as an independent risk factor for cognitive function. Glutamic acid decarboxylase 65 (GAD65) is the key enzyme responsible for γ-aminobutyric acid synthesis in the central nervous system. Antibodies against GAD65 (GAD65Abs) are not only detected in approximately 80% of early-onset type 1 DM, but also linked to several neurological disorders. AIM: This study aims to investigate the association between GAD65Ab titer levels and cognitive performance. In addition, we assessed the effect of GAD65Ab on cognitive function in adults with normal fasting glucose, prediabetes and DM. METHODS: A total of 328 subjects aged 49.10 ± 5.72 years were enrolled from the Third Health and Nutrition Examination Survey dataset. Cognitive performance was assessed by three computerized neurobehavioral tests, including the serial digit learning test, simple reaction time test (SRTT) and symbol-digit substitution test (SDST). RESULTS: Subjects with higher GAD65Ab titers had significantly poorer cognitive function in the SRTT and SDST (P < 0.05). Additionally, GAD65Ab was associated with cognitive decline in non-diabetic adults after adjusting for a number of relevant variables (P < 0.05 in both SRTT and SDST). CONCLUSIONS: These results indicate that GAD65Ab may be a potential marker for cognitive impairment in non-diabetic adults.

[Discussion on pT3 staging in TNM staging of AJCC 8(th) edition gallbladder carcinoma].

Objective: To discuss the rationality of stage pT3 in the AJCC 8(th) TNM criteria of gallbladder carcinoma. Methods: A retrospective study was performed to analyze the clinical and pathological data of 88 patients with pT3 gallbladder carcinoma admitted to Department of Second Biliary Surgery of Eastern Hepatobiliary Surgery Hospital, affiliated to Naval Medical University from May 2013 to September 2018.pT3 stage tumors were divided into two groups: (1) pT3a stage: tumors had penetrated serosa but not directly invaded liver and/or an adjacent organ or structure; (2) pT3b stage: tumor penetrating serosa and directly invaded liver and/or an adjacent organ or structure. There were 45 patients with pT3a stage, including 15 males and 30 females, aged 36 to 80 years, with a median age of 59 years; 43 patients with pT3b, including 24 males and 19 females, aged 41 to 78 years old, median aged 63 years old.Patients with pT3a and pT3b were further divided into two groups respectively: radical resection group and extended radical resection group according to surgical radicalization. Independent sample t-test was used for comparison between two groups with normal distribution measurement data. Wilcoxon rank sum test was used between groups of non-normally distributed measurement data.The comparison of the count data was performed by χ(2) test or Fisher exact probability method. Survival analysis was performed using Kaplan-Meier method, and survival rate was compared using Log-rank test. Results: (1)Serum total bilirubin(15.6(90.3)mmol/L), albumin(40.2(4.8)mmol/L), and CA19-9(132.90(455.78)U/ml) levels in pT3b patients were higher than that in pT3a patients(10.2(6.8)mmol/L, 41.8(4.9)mmol/L, 14.35(36.27)U/ml), respectively(Z=-3.816, -1.966, -3.739, all P<0.05),postoperative complication rate in pT3b patients(24.4%) was higher than that in pT3a patients(8.9%)(P<0.05),postoperative hospital stay(12(7)days) and overall hospital stay((26±17)days) of pT3b patients were longer than that of pT3a patients((10±5) days and (19±7)days) (P<0.05). (2) The 1-, 3-, 5-year survival rates of pT3b and pT3a patients were 53%,22%,22% and 69%, 46%,38%,and the median survival time was 13 months and 26 months, respectively. The difference in survival rates between the two groups was statistically significant(χ(2)=5.117, P=0.024). (3)The 1-, 3-year survival rates of extended radical resection group(n=19) and radical resection group(n=24) in the pT3b stage were 73%, 36% and 28%, 7%, respectively.The survival time was 20 months and 9 months,respectively,and the difference in survival rates between the two groups was statistically significant(χ(2)=4.976, P=0.026). Conclusions: pT3 gallbladder carcinoma could be further subdivided into pT3a stage and pT3b stage based on the TNM criteria of AJCC 8(th) gallbladder carcinoma. Extended radical resection for pT3b gallbladder carcinoma should be further considered after comprehensive assessment of the patient's basic condition and surgical tolerance.

LINC00052 inhibits tumor growth, invasion and metastasis by repressing STAT3 in cervical carcinoma.

OBJECTIVE: The vital role of long noncoding RNAs (lncRNAs) in tumor progression has been identified in numerous studies. In this research, the biological function of lncRNA LINC00052 during the development of cervical cancer was mainly explored. PATIENTS AND METHODS: LINC00052 expression was detected by quantitative Real-time polymerase chain reaction (qRT-PCR) in cervical cancer tissue samples and cell lines. Moreover, the correlation between LINC00052 expression level and disease-free survival rate of cervical cancer patients was analyzed. In vitro functions of LINC00052 in cervical cancer cells were evaluated by proliferation assay, wound healing assay and transwell assay. In addition, qRT-PCR and Western blot were utilized to explore the underlying mechanism of LINC00052 in mediating the progression of cervical cancer. RESULTS: LINC00052 expression level was lower in cervical cancer samples than that in adjacent tissues, which was correlated with disease-free survival time. Moreover, cell proliferation, migration and invasion were inhibited through overexpression of LINC00052 in vitro. The mRNA and protein expression of signal transducers and activators of transcription 3 (STAT3) was downregulated after overexpressing LINC00052 in cervical cancer cells. The STAT3 expression level was negatively correlated with the expression of LINC00052 in cervical cancer tissues. CONCLUSIONS: LINC00052 could repress metastasis and invasion of cervical cancer cell via suppressing STAT3. LINC00052 might be a novel tumor suppressor in cervical cancer.

[Applicational value of modified pancreaticojejunostomy and risk factors of pancreatic fistula following pancreaticoduodenectomy].

Objective: To compare the efficacy of modified pancreaticojejunostomy with traditional pancreaticojejunostomy following pancreaticoduodenectomy, and to investigate the risk factors of postoperative pancreatic fistula. Methods: Clinical data of 68 patients who underwent pancreaticoduodenectomy between October 2017 and October 2018 at the Second Department of Biliary Tract Surgery, Eastern Hepatobiliary Surgery Hospital was retrospectively collected and analyzed.According to the method of pancreaticojejunostomy, the patients were divided into two groups: modified pancreaticojejunostomy group (34 patients) and traditional pancreaticojejunostomy group (34 patients). There were 18 males and 16 females, aged (60.4±9.6) years of modified pancreaticojejunostomy groups; there were 17 males and 18 females, aged (58.9±10.9) years of traditional pancreaticojejunostomy group. The major postoperative complications such as pancreatic fistula were compared between the two groups, and the risk factors of postoperative pancreatic fistula were analyzed by univariate and multivariate analyses. Results: All of the 68 operations were successfully completed. The overall incidence of postoperative complications was 51.5% (35/68). The incidence of postoperative pancreatic fistula was 13.2% (9/68), of which all were cases of grade B.There were 16 patients (23.5%) occurred with abdominal infection, and 11 patients (16.2%) occurred with delayed gastric emptying, including 1 case of grade A, 1 case of grade B and 9 cases of grade C.And 9 patients (13.2%) occurred with postoperative bleeding was, including 2 cases of mild bleeding, 5 cases of moderate bleeding, and 2 cases of severe bleeding.Biliary leakage occurred in one patient (1.5%) and chylous leakage occurred in two patients (2.9%). The modified pancreaticojejunostomy could significantly reduce the incidence of postoperative bleeding compared with control group (χ(2)=4.610, P=0.032). And there were no significant differences for other postoperative complications between the two groups (all P>0.05). According to the results of univariate analysis: age, intraoperative bleeding and diameter of pancreatic tube were related factors affecting postoperative pancreatic fistula (P=0.025, 0.019, 0.017, respectively). The results of multivariate analysis showed that intraoperative bleeding>400 ml and diameter of pancreatic tube <3 mm were independent risk factors of pancreatic fistula following pancreaticoduodenectomy (P=0.025, 0.008, respectively). Conclusion: The modified pancreaticojejunostomy is feasible with advantages of reducing postoperative bleeding following pancreaticoduodenectomy.

The association between septicemia and the risk of multiple sclerosis: a nationwide register-based retrospective cohort study in Taiwan.

BACKGROUND: Multiple sclerosis (MS) is the most common inflammatory demyelinating disease of the central nervous system. Few studies focused on the relationship between septicemia and MS. AIM: To evaluate the potential impact of septicemia on risk for MS. DESIGN: Two cohorts of patients with septicemia and without septicemia were followed up for the occurrence of MS. METHODS: Patients of 482 790 with septicemia was enrolled from the National Health Insurance Research Database between 2001 and 2011 as the study group to match the 1 892 820 individuals, as the control group, by age and gender. Incidence of MS in both groups was calculated. Cox proportional-hazards regressions were performed for investigating hazard ratios (HR) for MS between groups. RESULTS: Septicemia patients had a 3.06-fold (95% CI: 2.16-4.32, P < 0.001) greater risk of developing MS than the matched group. In addition, higher severity of septicemia was associated with higher risk of developing MS (moderate: HR = 4.03, 95% CI: 2.53-6.45, P < 0.001; severe: HR = 11.1, 95% CI: 7.01-17.7, P < 0.001). Similar results also occurred in both male and female patients with septicemia (male: HR = 4.06, 95% CI: 2.17-7.58, P < 0.001; female: HR = 2.72, 95% CI: 1.79-4.11, P < 0.001). Patients without counterpart comorbidities had a significantly higher risk of MS than the controlled group (HR = 3.02, 95% CI: 2.10-4.35, P < 0.001). CONCLUSION: The results indicated septicemia is linked to an increased risk for MS. Aggressively preventing and treating septicemia may be warranted for one of precautionary strategies of MS.

A review of laser and light therapy in melasma.

Melasma is a dysregulation of the homeostatic mechanisms that control skin pigmentation and excess pigment is produced. Traditional treatment approaches with topical medications and chemical peels are commonly used but due to the refractory and recurrent nature of melasma, patients often seek alternative treatment strategies such as laser and light therapy. Several types of laser and light therapy have been studied in the treatment of melasma. Intense pulsed light, low fluence Q-switched lasers, and non-ablative fractionated lasers are the most common lasers and light treatments that are currently performed. They all appear effective but there is a high level of recurrence with time and some techniques are associated with an increased risk for postinflammatory hyper- or hypopigmentation. The number and frequency of treatments varies by device type but overall, Q-switched lasers require the greatest number of treatment applications to see a benefit. Vascular-specific lasers do not appear to be effective for the treatment of melasma. Ablative fractionated lasers should be used with caution because they have a very high risk for postinflammatory hypo- and hyperpigmentation. The use of nonablative fractionated laser treatments compared with other laser and light options may result in slightly longer remission intervals. Picosecond lasers, fractional radiofrequency, and laser-assisted drug delivery are promising future approaches to treat melasma. The goal of this review is to summarize the efficacy and safety of the most commonly used laser and light therapies to treat melasma, briefly present future laser-based treatment options for patients with melasma, and provide recommendations for treatment on the basis of the reviewed information.

Loss of p300 accelerates MDS-associated leukemogenesis.

The role that changes in DNA methylation and histone modifications have in human malignancies is poorly understood. p300 and CREB-binding protein (CBP), two distinct but highly homologous lysine acetyltransferases, are mutated in several cancers, suggesting their role as tumor suppressors. In the current study, we found that deletion of p300, but not CBP, markedly accelerated the leukemogenesis ofNup98-HoxD13 (NHD13) transgenic mice, an animal model that phenotypically copies human myelodysplastic syndrome (MDS). p300 deletion restored the ability of NHD13 expressing hematopoietic stem and progenitor cells (HSPCs) to self-renew in vitro, and to expand in vivo, with an increase in stem cell symmetric self-renewal divisions and a decrease in apoptosis. Furthermore, loss of p300, but not CBP, promoted cytokine signaling, including enhanced activation of the MAPK and JAK/STAT pathways in the HSPC compartment. Altogether, our data indicate that p300 has a pivotal role in blocking the transformation of MDS to acute myeloid leukemia, a role distinct from that of CBP.

Thermally Driven Electronic Topological Transition in FeTi.

Ab initio molecular dynamics, supported by inelastic neutron scattering and nuclear resonant inelastic x-ray scattering, showed an anomalous thermal softening of the M_{5}^{-} phonon mode in B2-ordered FeTi that could not be explained by phonon-phonon interactions or electron-phonon interactions calculated at low temperatures. A computational investigation showed that the Fermi surface undergoes a novel thermally driven electronic topological transition, in which new features of the Fermi surface arise at elevated temperatures. The thermally induced electronic topological transition causes an increased electronic screening for the atom displacements in the M_{5}^{-} phonon mode and an adiabatic electron-phonon interaction with an unusual temperature dependence.

Caring Difficulties and Coping Strategies for Pediatric Organ Transplant Recipients and Their Families During Dark Recovery Experiences in the Hospital: Perspective of Health Professionals in Taiwan.

BACKGROUND: This study explored caring difficulties and the reliable coping strategies for pediatric organ transplant recipients (POTR) and their families during their dark recovery experiences (DRE) in the hospital from the perspectives of Taiwan organ transplant health professionals (OTHP) in Taiwan. METHODS: A qualitative design was used with a purposive sample of OT surgeons (OTS) and nurses. Data were collected by face-to-face in-depth interviews and analyzed by content analysis. RESULTS: Fifty-five subjects (39 females, 16 males) participated in this project. They included 15 OTS and 40 nurses. The nurses included registered nurses (n = 27), nurse practitioners (n = 5), and assistant or head nurses (n = 8). Their ages ranged from 25 to 66 (M = 38.4) years old. Thirty-eight (69%) had a college education and 17 (31%) had a graduate education. Their OT careers ranged from between 3 to 40 (M = 23.8) years for OTS, and 0.5 to 15 (M = 4.10) years for the OT nursing group. Six types of coping strategies for caring difficulties were reported: (a) implementing humanistic care training programs, (b) developing clinical paths for complex multiple OT cases, (c) holding case conferences for successful and failed cases, (d) developing OT expert training programs for interdisciplinary team members, (e) integrating acute and long-term care teams for difficult OT cases and families, and (f) inviting assistance from social workers. CONCLUSIONS: This research identifies important care difficulties and provides coping strategies that help to empower OTHP to care for POTR and their families during DRE, including increasing the manpower of experienced OT staff, conducting systematic in-service training, building teamwork between OTHP, and establishing a good pediatric OTHP team with consensus and good communication channels so as to effectively deal with the difficulties faced when caring for the POTR, and further to effectively enhance the overall quality of clinical care of POTR.

Holistic care for pediatric organ transplant recipients and their families during their dark postoperative recovery stage in the hospital.

INTRODUCTION: This study explored the difficulties in caring for pediatric organ transplant recipients (POTR) and their families during dark recovery experiences (DRE) in the hospital from the perspectives of Taiwan organ transplant health professionals (OTHP). METHODS: A qualitative design was used, with a purposive sample of OTHP including OT surgeons (OTS) and nursing groups. Data were collected by thorough face-to-face interviews and were analyzed using content analysis. RESULTS: Fifty-five subjects (39 female, 16 male) participated in this project. They included 15 OTS and 40 nurses. The nurses included registered nurses (n = 27), nurse practitioners (n = 5), and assistant or head nurses (n = 8). Their ages ranged from 25 to 66 (mean = 38.4) years old. Thirty-eight (69%) had college education, and 17 (31%) had graduate education. Their OT careers ranged from between 3 to 40 (mean = 23.8) years for OTS, and 0.5 to 15 (mean = 4.10) years for the OT nursing group. Five types of caring difficulties were reported: (1) threat of OT failure, (2) work overload, (3) insufficient collaboration within interdisciplinary teams due to incongruent surgical and nursing opinions, (4) poor communication between OTHP and POTR, and (5) lack of competent professional OT care. CONCLUSIONS: The following suggestions were made to help relieve the OTHPs' stress in providing holistic care for POTR and their families during DRE: (1) increasing the amount of experienced OT manpower and professional communication liaisons, (2) providing systematic on-the-job interdisciplinary case seminars and OT workshops, and (3) enhancing the POTR's mental health care and helping manage their distress of DRE.

Factors contributing to poor sleep quality as perceived by heart transplant recipients in Taiwan.

BACKGROUND: The aims of this project were to explore the factors contributing to poor sleep quality at 1 to 3 years after heart transplantation (post-HT), and to explore economic problems and social support for HT recipients (HTRs). METHODS: This study used a cross-sectional retrospective triangulation approach combining qualitative and quantitative research method designs. Quantitative data included data from the visual analog scale and the Taiwanese version of the World Health Organization Quality of Life questionnaire. Qualitative data were derived from questions that explored physiological, psychological, and economic factors contributing to poor sleep quality postprocedure for HTRs. RESULTS: Sixty-four subjects (81% male, 19% female) participated in this research. Their ages ranged from 20 to 70 (M = 46.88 ± 12.12) years old. Their post-HT timeframe ranged from 1 to 4.10 years; 33% received preoperative extracorporeal membrane oxygenation support. Sleeping disturbances were reported by 72.7% of subjects after HT. Poor sleeping quality at 2 to 3 years post-HT (P = .028) was a complaint, and was worse than at 1 to 2 years post-HT (P = .008). Six physiological (62.5%) and 3 psychological (37.5%) contributing factors were further identified in qualitative interviews. Physiological factors were the major causes affecting their sleep quality 2 to 3 years after HT, whereas psychological factors arose from various family roles, responsibilities, and economic-related pressures. CONCLUSIONS: Medical teams should find the causes that lead to sleep disturbances and use the findings to improve HTR sleep quality. When the family financial status is affected, these teams should offer assistance and suggestions for patients who are unable to work due to post-HT physical decline. Establishing and providing good family support systems or patient support groups may allow patients to obtain physical, psychological, and spiritual comfort.
