Long-term outcome of multilayer flow modulator in aortic aneurysms

BACKGROUND

This retrospective study investigated the efficacy of endovascular treatment with multilayer flow modulators (MFMs) for treating aortic aneurysms in high-risk patients unsuitable for conventional treatments.

PATIENTS AND METHODS

Conducted from 2011 to 2019 at a single center, this retrospective observational study included 17 patients who underwent endovascular treatment with MFMs. These patients were selected based on their unsuitability for traditional surgical or endovascular procedures. The study involved meticulous pre-procedural planning, precise implantation of MFMs, and follow-up using CT angiography. The primary focus was on volumetric and flow volume changes in aneurysms, along with traditional diameter measurements. Moreover, the technical success and post-procedural complications were also registered.

RESULTS

The technical success rate was 100%, and 30-day procedural complication rate was 17.6%. Post-treatment assessments revealed that 11 out of 17 patients showed a decrease in flow volume within the aneurysm sac, indicative of a favorable hemodynamic response. The median decrease in flow volume was 12 ml, with a median relative decrease of 8%. However, there was no consistent reduction in aneurysm size; most aneurysms demonstrated a median increase in volume for 46 ml and median increase in diameter for 18 mm.

CONCLUSIONS

While MFMs offer a potential alternative for high-risk aortic aneurysm patients, their effectiveness in preventing aneurysm expansion is limited. The results suggest that MFMs can provide a stable hemodynamic environment but do not reliably reduce aneurysm size. This underscores the need for ongoing vigilance and long-term monitoring in patients treated with this technology.

Outcomes of Patients With Graves Disease 25 Years After Initiating Antithyroid Drug Therapy

CONTEXT

Graves disease (GD) is a leading cause of hyperthyroidism. Detailed investigations and predictors of long-term outcomes are missing.

OBJECTIVE

This work aimed to investigate the outcomes in GD 25 years after initiating antithyroid drug treatment, including disease course, clinical and biochemical predictors of relapse, and quality of life.

METHODS

A retrospective follow-up was conducted of GD patients that participated in a randomized trial from 1997 to 2001. Demographic and clinical data were obtained from medical records and questionnaires. Biobank samples were analyzed for inflammatory biomarkers and compared with age- and sex-matched healthy individuals.

RESULTS

We included 83% (182/218) of the patients from the original study. At the end of follow-up, normal thyroid function was achieved in 34%. The remaining had either active disease (1%), spontaneous hypothyroidism (13%), or had undergone ablative treatment with radioiodine (40%) or thyroidectomy (13%). Age younger than or equal to 40 years, thyroid eye disease (TED), smoking, and elevated levels of interleukin 6 and tumor necrosis factor receptor superfamily member 9 (TNFRS9) increased the risk of relapsing disease (odds ratio 3.22; 2.26; 2.21; 1.99; 2.36). At the end of treatment, CD40 was lower in patients who maintained normal thyroid function (P = .04). At the end of follow-up, 47% had one or more autoimmune diseases, including vitamin B12 deficiency (26%) and rheumatoid arthritis (5%). GD patients who developed hypothyroidism had reduced quality of life.

CONCLUSION

Careful lifelong monitoring is indicated to detect recurrence, hypothyroidism, and other autoimmune diseases. Long-term ATD treatment emerges as a beneficial first-line treatment option, especially in patients with young age at onset or presence of TED.

Revolutionizing Patient Monitoring in Age-Related Macular Degeneration: A Comparative Study on the Necessity and Efficiency of the AMD VIEWER

(1) Background: Age-related Macular Degeneration (AMD) is a critical condition leading to blindness, necessitating lifelong clinic visits for management, albeit with existing challenges in monitoring its long-term progression. This study introduced and assessed an innovative tool, the AMD long-term Information Viewer (AMD VIEWER), designed to offer a comprehensive display of crucial medical data-including visual acuity, central retinal thickness, macular volume, vitreous injection treatment history, and Optical Coherent Tomography (OCT) images-across an individual eye's entire treatment course. (2) Methods: By analyzing visit frequencies of patients with a history of invasive AMD treatment, a comparative examination between a Dropout group and an Active group underscored the clinical importance of regular visits, particularly highlighting better treatment outcomes and maintained visual acuity in the Active group. (3) Results: The efficiency of AMD VIEWER was proven by comparing it to manual data input by optometrists, showing significantly faster data display with no errors, unlike the time-consuming and error-prone manual entries. Furthermore, an elicited Net Promoter Score (NPS) of 70 from 10 ophthalmologists strongly endorsed AMD VIEWER's practical utility. (4) Conclusions: This study underscores the importance of regular clinic visits for AMD patients. It suggests the AMD VIEWER as an effective tool for improving treatment data management and display.

Mortality in Patients with Acute Coronary Syndrome-A Prospective 5-Year Follow-Up Study

Our objective was to compare long-term outcomes in patients with non-ST-elevation myocardial infarction (NSTEMI) and ST-elevation myocardial infarction (STEMI) between two time periods in Southern Norway. There are limited contemporary data comparing long-term follow-up after revascularization in the last decades. This prospective follow-up study consecutively included both NSTEMI and STEMI patients during two time periods, 2014-2015 and 2004-2009. Patients were followed up for a period of 5 years. The primary outcome was all-cause mortality after 1 and 5 years. A total of 539 patients with acute myocardial infarction (AMI), 316 with NSTEMI (234 included in 2014 and 82 included in 2007) and 223 with STEMI (160 included in 2014 and 63 included in 2004). Mortality after NSTEMI was high and remained unchanged during the two time periods (mortality rate at 1 year: 3.5% versus 4.9%, p = 0.50; and 5 years: 11.4% versus 14.6%, p = 0.40). Among STEMI patients, all-cause mortality at 1 year was reduced in 2014 compared to 2004 (1.3% versus 11.1%, p < 0.001; and 5 years: 7.0% versus 22.2%, p = 0.004, respectively). Time to coronary angiography in NSTEMI patients remained unchanged between 2014 and 2007 (28.2 h [IQR 18.1-46.3] versus 30.3 h [IQR 18.0-48.3], p = 0.20), while time to coronary angiography in STEMI patients was improved in 2014 compared with 2004 (2.8 h [IQR 2.0-4.8] versus 21.7 h [IQR 5.4-27.1], p < 0.001), respectively. During one decade of AMI treatment, mortality in patients with NSTEMI remained unchanged while mortality in STEMI patients decreased, both at 1 and 5 years.

Long-term follow up and comparison between conservative and interventional therapy in postoperative bronchopleural fistula-a cohort study

Background

Bronchopleural fistula (BPF) is a relatively rare postoperative complication with high mortality. The management is tough and controversial. The aim of this study was to compare the short and long-term outcomes between the conservative and the interventional therapy in postoperative BPF. We also concluded our own strategy and experience of treatment in postoperative BPF.

Methods

Postoperative BPF patients with malignancies, aged from 18 to 80 years old who had undergone thoracic surgery between June 2011 and June 2020, were included in this study and followed up from 20 months to 10 years. They were retrospectively reviewed and analyzed.

Results

Ninety-two BPF patients were included in this study, 39 of whom underwent interventional treatment. Significant differences were found in the 28-day and the 90-day survival rates between the conservative and the interventional therapy (P=0.001, 43.40% vs. 76.92%; P=0.006, 35.85% vs. 66.67%). Simple conservative therapy was independently associated with 90-day mortality between the groups in postoperative BPF [P=0.002, hazards ratio (HR) =2.913, 95% confidence interval (CI): 1.480-5.731].

Conclusions

Postoperative BPF is notorious for its high mortality. Surgical and bronchoscopic interventions are recommendable in postoperative BPF as they guarantee better short and long-term outcomes compared with the conservative therapy.

[Long-term hearing outcomes of children with cochlear implant]

Objective:To investigate the long-term rehabilitation outcomes of children with cochlear implants（CI） and provide constructive guidance for clinical application. Methods:Fifteen children with unilateral CI over 5 years（CI group） were recruited. Ten children with normal hearing were recruited as the healthy control group. The project collected aided sound-field hearing thresholds and speech recognition scores using disyllabic words and C-HINT sentences with and without speech noise for 15 children with unilateral CI. In addition, children's guardians were requested to fill out the Mandarin Parental Perspectives questionnaire（MPP） in order to evaluate the hearing aspects of quality of life. MPP results from the 15 children were then compared with previous responses from 17 unilateral CI children whose overall CI wearing time was one year（CI control group）. Results:The aided pure-tone average（PTA） of the recruited children was below 35 dB HL, all children reached 80% for the speech recognition test in a quiet environment, yet their performance decreased in a noisy environment. Regarding the hearing aspects of the MPP questionnaire results, recruited children demonstrated better results than those from CI control group（P<0.05）. Speech noise had a significant impact on the recognition rate, and the CI group had higher recognition rate scores in the quiet environment than in the noise environment（two-syllable words t=18.81, P<0.001, short sentences t=16.48, P<0.001）. In the comparison of quality of life, in the dimension of "support for children", both the CI group and the CI control group can obtain better benefits, and there is no statistically significant difference between the groups（P>0.05）. The CI group benefited more significantly, and the scores were higher than those of the CI control group（P<0.05）. Conclusion:The long-term hearing outcome of children with CI is adequate for daily communication, but there is still a gap compared with hearing children of the same age, and they still need support from the entire society.

Safety and efficacy of a novel three-dimensional printed microporous titanium prosthesis for total wrist arthroplasty in the treatment of end-stage wrist arthritis

Background: Total wrist arthroplasty is an effective treatment for end-stage wrist arthritis from all causes. However, wrist prostheses are still prone to complications such as prosthesis loosening and periprosthetic fractures after total wrist arthroplasty. This may be due to the wrist prosthesis imprecise matching with patient's bone. In this study, we designed and developed a personalized three-dimensional printed microporous titanium artificial wrist prosthesis (3DMT-Wrist) for the treatment of end-stage wrist joint, and investigated its safety and effectiveness. Methods: Total wrist arthroplasty was performed using 3DMT-Wrist in 14 cases of arthritis between February 2019 and December 2021. Preoperative and postoperative visual analog scale scores, QuickDASH scores, wrist range of motion, and wrist grip strength were evaluated. Data were statistically analyzed using the paired samples t-test. Results: After 19.7 ± 10.7 months of follow-up, visual analog scale decreased from 66.3 ± 8.9 to 6.7 ± 4.4, QuickDASH scores decreased from 47.4 ± 7.3 to 28.2 ± 7.6, grip strength increased from 5.6 ± 1.4 to 17.0 ± 3.3 kg. The range of motion improved significantly in palmar flexion (30.1° ± 4.9° to 44.9° ± 6.5°), dorsal extension (15.7° ± 3.9° to 25.8° ± 3.3°), ulnar deviation (12.2° ± 3.9° to 20.2° ± 4.3°) and radial deviation (8.2° ± 2.3° to 16.2 ± 3.1). No dislocation or loosening of the prosthetic wrist joint was observed. Conclusion: Total wrist arthroplasty using 3DMT-Wrist is a safe and effective new treatment for various types of end-stage wrist arthritis; it offers excellent pain relief and maintains the range of motion.

The continuing evolution of birth cohort studies: achievements and challenges

Well-designed birth cohorts are able to estimate prevalence/distribution of various health events/outcomes, and to link early-life origins with adult health and function. The past two decades have seen a surge in the establishment of new birth cohorts and their accompanying research. We discussed distinct designs of current birth cohort studies, reviewed their achievements, and highlighted insights obtained from birth cohort studies, as well as challenges we are facing. Birth cohort studies are providing increasing opportunities to identify determining factors for short- and long-term health, yielding substantial evidence to uncover biological mechanisms of diseases and phenotypes, and providing further insights for public health. Dynamic monitoring, accurate measurements, long-term follow-ups and collaborative efforts are warranted in new birth cohorts to elucidate the nature of life course relationships in contemporary generation.

Long-term Outcomes of Behavior Therapy for Youth With Tourette Disorder

OBJECTIVE

To determine the long-term durability of behavior therapy for tics among youth with Tourette disorder and persistent (chronic) motor or vocal tic disorders.

METHOD

Of the 126 youth who participated in a randomized controlled trial of behavior therapy 11 years prior, 80 were recruited for this longitudinal follow-up. Consenting participants were interviewed in person or remotely (Web-based video) by trained evaluators to determine the course of tics, current tic severity, and tic-related impairment. Recruitment and data collection occurred between 2014 and 2019, with an average follow-up duration of 11.2 years.

RESULTS

Treatment responders to both conditions in the original trial achieved partial, but not full, tic remission. Tic severity also decreased significantly across the sample, with 40% reporting partial remission. Behavior therapy responders (n = 21) in the original trial were more likely (67%) to achieve remission at follow-up (Total Tic Score = 12.52, SD = 10.75) compared to psychoeducation/supportive therapy responders (n = 6, 0%) at follow-up (Total Tic Score = 20.67, SD = 6.92) on the Yale Global Tic Severity Scale. Tic-related impairment decreased across the sample, with no significant differences between treatment groups or responders.

CONCLUSION

Despite limitations of unmeasured variables and veracity of self-report at follow-up, this study supports guidelines recommending behavior therapy as the first-line intervention for tics. Further investigation of behavior therapy as an early preventive intervention also merits attention.

Late effects care for childhood brain Tumor Survivors: A Quality-Improvement Initiative

Childhood and adolescent brain tumor survivors are at risk for long-term consequences of therapy. We reviewed adherence to long-term follow-up (LTFU) guidelines, assessed provider perspectives, and studied the needs, experience and quality of life (QOL) of pediatric malignant brain tumor survivors in the McMaster Children's Hospital Neuro-Oncology clinic. LTFU areas for improvement were evaluated using an anonymous health provider needs assessment questionnaire. The Cancer Care Experience Questionnaire (CCEQ), Cancer Worry Scale (CWS), Self-Management Skills Scale (SMSS), and PedsQL measured parents/patients' needs and QOL. Individual care plans were based on the Children's Oncology Group (COG) LTFU guidelines. Based on 17 responses, staff perceived areas for improvement included: increased multi-disciplinary participation, improved patient education and increased surveillance for therapy-related late effects. Thirty-two families participated, most felt they received high-quality care. Mean cancer worry scores were low (71.8 (± 28.4)). Survivors reported limited self-management skills (58.5 (±18.2)), requiring support with medical needs and activities of daily living. Overall median QOL scores were 'good' (parental report 72.3 (±17.7), survivor 68.2 (±16.6)). Utilizing survivorship guidelines and assessments from patients, caregivers and health providers, we implemented improvements in our provision of neuro-oncology survivorship care. Lessons learned may assist other LTFU programs.

Fecal Microbiota Transplantation Ameliorates Active Ulcerative Colitis by Downregulating Pro-inflammatory Cytokines in Mucosa and Serum

Background

Ulcerative colitis (UC) is a multi-factor disease characterized by alternating remission periods and repeated occurrence. It has been shown that fecal microbiota transplantation (FMT) is an emerging and effective approach for UC treatment. Since most existing studies chose adults as donors for fecal microbiota, we conducted this study to determine the long-term efficacy and safety of the microbiota from young UC patient donors and illustrate its specific physiological effects.

Methods

Thirty active UC patients were enrolled and FMT were administered with the first colonoscopy and two subsequent enema/transendoscopic enteral tubing (TET) practical regimens in The First Affiliated Hospital of Anhui Medical University in China. Disease activity and inflammatory biomarkers were assessed 6 weeks/over 1 year after treatment. The occurrence of adverse events was also recorded. The samples from blood and mucosa were collected to detect the changes of inflammatory biomarkers and cytokines. The composition of gut and oral microbiota were also sampled and sequenced to confirm the alteration of microbial composition.

Results

Twenty-seven patients completed the treatment, among which 16 (59.3%) achieved efficacious clinical response and 11 (40.7%) clinical remission. Full Mayo score and calprotectin dropped significantly and remained stable over 1 year. FMT also significantly reduced the levels of C-reactive protein (CRP), interleukin-1 beta (IL-1β), and interleukin-6 (IL-6). The gut microbiota altered significantly with increased bacterial diversity and decreased metabolic diversity in responsive patients. The pro-inflammatory enterobacteria decreased after FMT and the abundance of Collinsella increased. Accordingly, the altered metabolic functions, including antigen synthesis, amino acids metabolism, short chain fatty acid production, and vitamin K synthesis of microbiota, were also corrected by FMT.

Conclusion

Fecal microbiota transplantation seems to be safe and effective for active UC patients who are nonresponsive to mesalazine or prednisone in the long-term. FMT could efficiently downregulate pro-inflammatory cytokines to ameliorate the inflammation.

Follow up of Kawasaki disease based on nationwide survey data in Japan: Mortality among those with a history of Kawasaki disease in Japan: Results of a 30-year follow up: Mortality among those with a history of Kawasaki disease in Japan: Results of a 30-year follow up

BACKGROUND

The long-term prognosis of those with a history of Kawasaki disease (KD) is still unknown.

METHODS

Using a permanent registry system in Japan (koseki), 6,576 persons with a history of KD were followed up. The average follow-up period was 30 years. The endpoint was death.

RESULTS

With a 99.5% follow-up rate, 68 deaths (48 males and 20 females) were observed. The overall standardized mortality ratio, of which reference was vital statistics in Japan, was not elevated. However, the observation according to the presence or absence of cardiac sequelae showed that the standardized mortality ratio for those with cardiac sequelae significantly elevated. Nine persons, all of whom were males, died of KD (including those cases where KD was suspected), but all deaths occurred in individuals who were under 30 years of age.

CONCLUSIONS

This study revealed the long-term prognosis for KD, but almost all participants were younger than 40 years. Continuing follow up of this cohort is required to clarify whether a history of KD relates to the development of atherosclerosis when participants become middle aged or older.

A questionnaire study of support for adult survivors of childhood cancer

BACKGROUND

Childhood cancer survivors (CCSs) entering adulthood experience different problems, including late therapy-related complications. Long-term follow up (LTFU) is important for early intervention and psychosocial support for CCSs with late complications but it is frequently discontinued. This study aimed (i) to identify clearly the factors responsible for LTFU discontinuation, and (ii) to define the support needs of CCSs.

METHODS

From July, 2017 to March, 2019 we conducted a questionnaire survey of 121 CCSs aged ≥ 18 years at the time of the survey to investigate people who have experienced childhood cancer and identify their support needs. This was conducted in cooperation with patient associations throughout Japan. The LTFU levels were determined by CCSs themselves based on their treatment history. Long-term follow-up rates and LTFU discontinuation factors were assessed using the Kaplan-Meier method and the Cox proportional-hazards model.

RESULTS

Late complications were the most common problem encountered by CCSs (80%). The most common support need was "explanation of late complications by a physician," reported by 86.9% of respondents. The rate of LTFU continuation decreased over time. The LTFU was discontinued both for physicians' reasons (35.6%) and patients' reasons (64.4%). Not knowing the extent or level of one's LTFU was reported to be an independent factor (P < 0.05) preventing LTFU continuation. As necessary support to continue LTFU, 67.9% of respondents stated the need for "explanation of LTFU by a doctor" and 60.7% stated "convenience of outpatient visit".

CONCLUSIONS

Childhood cancer survivors require support, especially for late complications. It is necessary to continue LTFU, raising LTFU awareness among physicians and CCSs.

Maintenance of intervention effects: long-term outcomes for participants in a group talk-therapy trial in the Democratic Republic of Congo

BACKGROUND

Despite the growth of psychotherapy trials in low- and middle-income countries, there have been limited follow-up studies of more than 2 years. This study follows up female sexual violence survivors approximately 6 years after completing a 12-session group cognitive processing therapy (CPT) program in the eastern Democratic Republic of Congo.

METHODS

Baseline trial data were collected in December 2010 from 134 women in 7 study villages randomly allocated to CPT. Study women were over 18 years, reported personally experiencing or witnessing sexual violence, and reported elevated depression, anxiety and/or posttraumatic stress symptoms. Women were followed up (1) post-treatment (6-months after baseline); (2) 6 months later; (3) 12 months later; and (4) in March 2017 (6.3 years after baseline). At the long-term follow-up, 103 women (77%) in 6 of 7 CPT villages were re-assessed; one village was not visited due to ongoing insecurity.

RESULTS

We found strong continued intervention effects; nearly all women maintained treatment impacts over the first two years; at long-term follow-up, approximately half continued to maintain low symptom scores. Relapse rates for probable PTSD and probable depression and anxiety were 20%.

CONCLUSIONS

This study extends prior research to show that treatment impacts can be maintained for several years despite experiences of ongoing trauma. The women described continuing to meet with the women in their therapy group and using the skills they learned in the psychotherapy, providing evidence of the potential for these programs to provide valuable social supports and skills that people use as they continue to face adversity.

Clinical characteristics and long-term outcome of 223 patients with mycosis fungoides at a single tertiary center in Korea: A 29-year review

BACKGROUND

Data regarding Asian patients with mycosis fungoides (MF) are limited.

OBJECTIVE

We aimed to investigate the clinical profile and long-term outcomes of patients with MF in Korea.

METHODS

A retrospective review of 223 patients with MF who were followed up for more than 6 months or died of MF within 6 months of diagnosis was performed.

RESULTS

Approximately 96.4% and 3.6% of the patients had an early stage and advanced stage, respectively. The mean age at diagnosis was 44.8 years. The mean duration of symptoms before diagnosis was 47.0 months. Various subtypes were noted, including mycosis fungoides palmaris et plantaris (21.5%), folliculotropic (8.5%), pityriasis lichenoides-like (6.7%), ichthyosiform (4.0%), lichenoid purpura-like (2.7%), and hypopigmented (2.2%) MF. Juvenile patients accounted for 16.6%. The higher the skin T stage, the poorer the response to treatment. The 10-year overall survival was 96.8% in early-stage patients and 25.0% in advanced-stage patients. General prognosis was favorable, while recurrence and subtype switching were seen in 29.4% and 2.7% of patients, respectively.

LIMITATIONS

Our patients may not represent all Korean patients with MF.

CONCLUSION

MF in Korea has a high proportion of variants, a younger age at onset, and favorable prognosis. A high index of suspicion and skin biopsy are needed for early diagnosis.

Acute Kidney Injury in Critically Ill Children Is Not all Acute: Lessons Over the Last 5 Years

Acute kidney injury (AKI) in the pediatric intensive care unit (PICU) is an important risk factor for increased morbidity and mortality during hospitalization. Over the past decade, accumulated data on children and young people indicates that acute episodes of kidney dysfunction can have lasting consequences on multiple organ systems and health outcomes. To date, there are no guidelines for follow-up of surviving children that may be at risk of long-term sequelae following AKI in the PICU. This narrative review aims to describe literature from the last 5 years on the risk of medium and long-term kidney and non-kidney outcomes after AKI in the PICU. More specifically, we will focus on outcomes in children and young people following AKI in the general PICU population and children undergoing cardiac surgery. These outcomes include mortality, hypertension, proteinuria, chronic kidney disease, and healthcare utilization. We also aim to highlight current gaps in knowledge in medium and long-term outcomes in this pediatric population. We suggest a framework for future research to develop evidence-based guidelines for follow-up of children surviving an episode of critical illness and AKI.

A 10-year observational single-center study of retroperitoneal unicentric Castleman disease

Diagnosis of unicentric Castleman disease (UCD) is not easy before the resection and obtainment of pathological result. We retrospectively summarized 10-year experience of clinical evaluation and management for retroperitoneal UCD in Peking Union Medical College Hospital (PUMCH) between December 1, 2009 and December 31, 2019. Seventy two UCD patients with pathological diagnosis after resection were screened out. Among them 25 patients had retroperitoneal UCD. The average age of the 25 patients was 43.80 ± 12.79, and 52.00% were male. No patients had systemic symptoms, and 1 patient got preoperative treatment. The average size of masses was 5.59 ± 2.86 cm. The UCD sites included kidney, adrenal area, perinephric area, pancreas, peripancreatic area, area of descending part of duodenum, periaortic area or beside iliac artery, and others. The masses presented different degree of enhancement on CT scans and hypoecho or isoecho on ultrasound. Increased metabolism could be found on 18F-fluorodeoxyglucose positron emission tomography-computed tomography (18F-FDG PET/CT). Some patients had positive results on somatostatin receptor imaging, but none had positive results on 131I-metaiiodo-benzylguanidine (131I-MIBG). Some patients presented the elevated level of interleukin-6 (IL-6), 24hour-urinary catecholamine and tumor markers. All the patients received complete resection of masses and 96.00% had hyaline-vascular type pathology except 1 patient (plasma cell-type). Ninety two percent patients received a long-term follow-up with an average follow-up time of 35.48 ± 33.90 months. No patients died or experienced relapse during follow-up. Differential diagnosis of retroperitoneal UCD may be difficult according to imaging and laboratorial examinations. Differential diagnosis with pheochromocytomas/paragangliomas should be taken into special consideration. Different imaging examinations, such as CT/MRI, 18F-PET/CT, somatostatin receptor imaging and 131I-MIBG, can be combined for differential analysis. Complete resection is the best treatment and could provide a final pathological diagnosis.

Design of the Arizona CoVHORT: A Population-Based COVID-19 Cohort

This study is a prospective, population-based cohort of individuals with a history of SARS-CoV-2 infection and those without past infection through multiple recruitment sources. The main study goal is to track health status over time, within the diverse populations of Arizona and to identify the long-term consequences of COVID-19 on health and well-being. A total of 2,881 study participants (16.2% with a confirmed SARS-CoV-2 infection) have been enrolled as of December 22, 2020, with a target enrollment of 10,000 participants and a planned follow-up of at least 2 years. This manuscript describes a scalable study design that utilizes a wide range of recruitment sources, leveraging electronic data collection to capture and link longitudinal participant data on the current and emerging issues associated with the COVID-19 pandemic. The cohort is built within a collaborative infrastructure that includes new and established partnerships with multiple stakeholders, including the state's public universities, local health departments, tribes, and tribal organizations. Challenges remain for ensuring recruitment of diverse participants and participant retention, although the electronic data management system and timing of participant contact can help to mitigate these problems.

Use of electronic patient data storage for evaluating and setting the risk category of late effects in childhood cancer survivors

BACKGROUND

Many of the late effects of cancer treatment in childhood may occur even decades after the treatment, and only a minority of the survivors remain as healthy as their peers. Providing appropriate long-term care for childhood cancer survivors after transition to primary health care is a challenge. Both survivors and primary care providers need information on potential late effects. The lack of a systematic late effect follow-up plan may lead to excessive use of health care services or delayed intervention. While manual compilation of individual follow-up plans is time consuming for experienced clinicians, electronic algorithms may be feasible.

PROCEDURE

In Finland, international guidelines for determining the risk of late effects have been implemented. Nationally, Turku University Hospital was asked with developing an automatized system for calculating the risk of late effects, based on electronic patient records saved in the hospital data lake. An electronic algorithm that uses details from exposure-based health screening guidelines published by the Children's Oncology Group was created. The results were compared with those manually extracted by an experienced clinician.

RESULTS

Significant concordance between the manual and algorithm-based risk classification was found. A total of 355 patients received a classification using the algorithm, and 325 of those matched with the manual categorization, producing a Cohen's coefficient of 0.91 (95% confidence interval 0.88-0.95).

CONCLUSION

Automated algorithms can be used to categorize childhood cancer survivors efficiently and reliably into late effect risk groups. This further enables automatized compilation of appropriate individual late effect follow-up plan for all survivors.

Nasopharyngeal carcinoma in children and young adults-Beyond 5-year survival

Nasopharyngeal carcinoma (NPC) is a rare and locally aggressive form of childhood cancer. Treatment of NPC includes chemotherapy and radiotherapy. With current treatment protocols, survival rates for patients with nonmetastatic disease is over 80%. Data regarding very late events including long-term treatment-related morbidities and second malignancies are scarce. We present our data on 42 patients with NPC treated in Israel between 1989 and 2014, and followed until 2019. During follow up, five patients had disease recurrence, and four children developed secondary malignancy. Median time to diagnosis of secondary malignancy was 105 months. Eighty-eight percent of patients have long-term treatment-related morbidities.

Long-term health of children conceived after assisted reproductive technology

The aim of this narrative review is to summarize the present knowledge on long-term outcome of children born after assisted reproductive technologies (ART). The main outcomes covered are neurodevelopment including cerebral palsy, cognitive development, attention deficit hyperactivity disorder and autism spectrum disease, growth, cardiovascular function, diabetes type 1, asthma, malignancies, and reproductive health. Results have mainly been obtained from systematic reviews/meta-analyses and large registry studies. It has been shown that children born after ART, when restricted to singletons, have a similar outcome for many health conditions as their spontaneously conceived peers. For some outcomes, particularly cardiovascular function and diabetes, studies show some higher risk for ART singletons or subgroup of ART singletons. The fast introduction of new ART techniques emphasizes the importance of continuous surveillance of children born after ART.

Longitudinal Study of Three microRNAs in Duchenne Muscular Dystrophy and Becker Muscular Dystrophy

Our objective was to investigate the potential of three microRNAs, miR-181a-5p, miR-30c-5p, and miR-206 as prognostic biomarkers for long-term follow up of Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) patients. We analyzed the expression of three microRNAs in serum of 18 patients (DMD 13, BMD 5) and 13 controls using droplet digital PCR. Over 4 years a minimum of two and a maximum of three measurements were performed at different time points in the same patient. Correlations between microRNA serum levels, age, and functional outcome measures were analyzed. We show the individual evolution of the levels of the three microRNAs in 12 patients and also the effect of corticosteroid treatment on microRNAs expression. We measure the expression of three microRNAs in the muscle of six DMD patients and also the expression of target genes for miR-30c. We found that levels of miR-30c and miR-206 remained significantly elevated in DMD patients relative to controls over the entire study length. The introduction of the corticosteroid treatment did not significantly influence the levels of these microRNAs. We report a trend for microRNA levels to decrease with age. Moreover, miR-206 expression levels are capable to distinguish DMD from BMD patients according to ROC analysis. We found miR-30c expression decreased in the muscle of DMD patients and marked upregulation of the target genes for this microRNA. MiR-30c and miR-206 represent sensitive biomarkers for DMD, while miR-206 may have an additional value to distinguish the DMD and BMD phenotype. This may be particularly relevant to assess the effectiveness of treatments aimed at converting the DMD to the less-severe BMD like phenotype.

Long-Term Outcome of Repetitive Transcranial Magnetic Stimulation in a Large Cohort of Patients With Cocaine-Use Disorder: An Observational Study

Background: Cocaine is a psychostimulant drug used as performance enhancer throughout history. The prolonged use of cocaine is associated with addiction and a broad range of cognitive deficits. Currently, there are no medications proven to be effective for cocaine-use disorder (CocUD). Previous preliminary clinical work suggests some benefit from repetitive transcranial magnetic stimulation (rTMS) stimulating the prefrontal cortex (PFC), involved in inhibitory cognitive control, decision-making and attention. All published studies to date have been limited by small sample sizes and short follow-up times. Methods: This is a retrospective observational study of 284 outpatients (of whom 268 were men) meeting DSM-5 criteria for CocUD. At treatment entry, most were using cocaine every day or several times per week. All patients underwent 3 months of rTMS and were followed for up to 2 years, 8 months. Self-report, reports by family or significant others and regular urine screens were used to assess drug use. Results: Median time to the first lapse (resumption of cocaine use) since the beginning of treatment was 91 days. For most patients, TMS was re-administered weekly, then monthly, throughout follow-up. The decrease in frequency of rTMS sessions was not accompanied by an increase in lapses to cocaine use. Mean frequency of cocaine use was <1·0 day/month (median 0), while serious rTMS-related adverse events were infrequent, consistent with published reports from smaller studies. Conclusions: This is the first follow-up study to show that rTMS treatment is accompanied by long-lasting reductions in cocaine use in a large cohort.

Clinical and radiological outcomes of infantile hemangioma treated with oral propranolol: A long-term follow-up study

Infantile hemangiomas (IH) undergo rapid growth during early infancy followed by gradual involution. After involution, a part of IH remain as residual lesions. Since 2008, oral propranolol has been widely used in the treatment of IH. However, long-term outcome of IH treated with propranolol remains unknown. This study aimed to investigate the sequelae of IH treated with propranolol. In this study, propranolol was given at a dose of 2 mg/kg per day at the age of 3.8 ± 2.5 months and follow-up visits were arranged to continue at least through the age of 4 years. Types of sequela were recorded and classified as four degrees ("none", "minimal", "significant" and "severe" at last visit), then subsequent therapy was evaluated with the help of magnetic resonance imaging (MRI). A total of 73 patients with complete follow up were enrolled in the study. The most common types of sequela were telangiectasia, fibrofatty tissue and erythema. Significant and severe sequelae were observed in 72.4% of treated IH; superficial IH led to more but not significantly significant and severe sequelae than mixed IH (P > 0.05). Despite propranolol treatment, surgery was still needed in 37.5% of IH at a mean age of 70.3 months, and for the main reason of surgery, fibrofatty or hemangioma residua, MRI was useful for us to choose an appropriate surgical procedure.

A prospective study of women and girls undergoing fertility preservation due to oncologic and non-oncologic indications in Sweden-Trends in patients' choices and benefit of the chosen methods after long-term follow up

INTRODUCTION

In Scandinavian countries, programs for fertility preservation are offered free of charge at tertiary-care university hospitals to all patients facing treatments with risk of subsequent sterility. In this prospective study we aimed to investigate trends in female patients' choices after counseling and fertility preservation outcomes during follow up in relation to benign vs malignant indications.

MATERIAL AND METHODS

Data on 1254 females including 1076 adults and 178 girls who received fertility preservation counseling for either oncologic (n = 852) or benign indications (n = 402) at Karolinska University Hospital, Stockholm, between 1 October 1998 and 1 December 2018 were analyzed. As appropriate, t tests and chi-square tests were used to compare groups. Logistic regression was used to compare outcomes among groups depending on indications.

RESULTS

Adult women generally elected to undergo oocyte retrieval after controlled ovarian stimulation for cryopreservation of embryos or oocytes (n = 538, 73%), whereas a minor proportion opted for cryopreservation of ovarian tissue retrieved through laparoscopy (n = 221, 27%). More than half of the women with a partner chose either not to fertilize their oocytes aiming at cryopreservation of oocytes or to share obtained oocytes attempting both cryopreservation of oocytes and cryopreservation of embryos. All pre-pubertal (n = 48) and 73% of post-pubertal girls (n = 66) elected cryopreservation of ovarian tissue. In recent years, an increasing number of teenagers have opted for controlled ovarian stimulation aiming at cryopreservation of oocytes, either before (n = 24, 17%) or after completion of cancer treatment (n = 15, 10%). During follow up, 27% of the women returned for a new reproductive counseling, additional fertility preservation or to attempt pregnancy. Utilization rates among individuals who were alive and of childbearing age by December 2018 indicated 29%, 8% and 5% for embryos, oocytes and ovarian tissue with live birth rates of 54%, 46% and 7%, respectively. Women with benign indications were significantly younger than women with previous malignant indications at the time of attempting pregnancy. Although the pregnancy rates were similar among both groups, the live birth rate was significantly higher in women with benign vs previous malignant indications (47% vs 21%, P = .002).

CONCLUSIONS

Trends in fertility preservation choices have changed over time. Women with previous malignancy had lower live birth rates than women with benign fertility preservation indications.

Long-Term Safety and Efficacy of Single or Repeated Intra-Articular Injection of Allogeneic Neonatal Mesenchymal Stromal Cells for Managing Pain and Lameness in Moderate to Severe Canine Osteoarthritis Without Anti-inflammatory Pharmacological Support: Pilot Clinical Study

Objective: To explore the long-term safety and efficacy of canine allogeneic mesenchymal stromal cells (MSC) administered intra-articularly as single or repeated injections in appendicular joints of dogs affected by moderate to severe refractory osteoarthritis.

Study Design: 22 pet dogs were recruited into a non-randomized, open and monocentric study initially administering one cellular injection. A second injection was offered after 6 months to owners if the first injection did not produce expected results.

Materials and Methods: Anti-inflammatory treatment (if prescribed) was discontinued at last one week before the onset of treatment. Each injection consisted of at least 10 million viable neonatal allogeneic mesenchymal stromal cells obtained from fetal adnexa. Medical data was collected from veterinary clinical evaluations of joints up to 6 months post-injection and owner's assessment of their dog's mobility and well-being followed for a further 2 years when possible.

Results: Mild, immediate self-limiting inflammatory joint reactions were observed in 5/22 joints after the first injection, and in almost all dogs having a subsequent injection. No other MSC-related adverse medical events were reported, neither during the 6 months follow up visits, nor during the long-term (2-years) safety follow up. Veterinary clinical evaluation showed a significant and durable clinical improvement (up to 6 months) following MSC administration. Eight dogs (11 joints) were re-injected 6 months apart, sustaining clinical benefits up to 1 year. Owner's global satisfaction reached 75% at 2 years post-treatment

Conclusion: Our data suggest that a single or repeated intra-articular administration of neonatal MSC in dogs with moderate to severe OA is a safe procedure and confer clinical benefits over a 24-month period. When humoral response against MSC is investigated by flow cytometry, a positive mild and transient signal was detected in only one dog from the studied cohort, this dog having had a positive clinical outcome.

Fifteen years' experience of implantable cardioverter defibrillator in children and young adults: Mortality and complications study

BACKGROUND

Young implantable cardioverter defibrillator (ICD) recipients have a high rate of complications, some of which seem to be underestimated. We report our clinical experience with ICD therapy in children and young adults during a 15 year follow up.

METHODS

We reviewed the database of ICD recipients at the present institution and chose 73 consecutive patients who underwent implantation at age 6-21 years. We analyzed intervention rate, mortality, rate and characteristics of complications and treatment options.

RESULTS

A total of 20/73 patients (27.4%) received ≥1 episode of appropriate therapy (AT) for ventricular tachycardia/ventricular fibrillation (anti-tachycardia pacing or shock) and 24/73 patients (32.8%) had one or multiple episodes of inappropriate therapy (IT). Eight patients (11%) had both interventions: AT + IT. A total of 15/73 patients (20.5%) had ventricular lead dysfunction, with 13 re-implantations (17.8%) of a new system. Four of 73 patients (5.5%) had infection: endocarditis or device pocket infection. A total of 2/73 patients (2.7%) died due to ventricular lead dysfunction, while 22/73 patients (30.1%) needed elective device replacement, five of them twice (6.8%).

CONCLUSION

Endocardial ICD implantation in children and young adults is a feasible and life-saving procedure, according to the present 15 year follow up. The rate of complications including IT was high: 72.8% in the young ICD recipients. Re-implantation of a new system was often required due to ventricular lead dysfunction or infection in 25% of the patients.

Recurrence of vulval intraepithelial neoplasia following treatment with cidofovir or imiquimod: results from a multicentre, randomised, phase II trial (RT3VIN)

OBJECTIVE

To compare the recurrence rates after complete response to topical treatment with either cidofovir or imiquimod for vulval intraepithelial neoplasia (VIN) 3.

DESIGN

A prospective, open, randomised multicentre trial.

SETTING

32 general hospitals located in Wales and England.

POPULATION OR SAMPLE

180 patients were randomised consecutively between 21 October 2009 and 11 January 2013, 89 to cidofoovir (of whom 41 completely responded to treatment) and 91 to imiquimod (of whom 42 completely responded to treatment).

METHODS

After 24 weeks of treatment, complete responders were followed up at 6-monthly intervals for 24 months. At each visit, the Common Terminology Criteria for Adverse Events (CTCAE) v3.0 was assessed and any new lesions were biopsied for histology.

MAIN OUTCOME MEASURES

Time to histologically confirmed disease recurrence (any grade of VIN).

RESULTS

The median length of follow up was 18.4 months. At 18 months, more participants were VIN-free in the cidofovir arm: 94% (95% CI 78.2-98.5) versus 71.6% (95% CI 52.0-84.3) [univariable hazard ratio (HR) 3.46, 95% CI 0.95-12.60, P = 0.059; multivariable HR 3.53, 95% CI 0.96-12.98, P = 0.057). The number of grade 2+ events was similar between treatment arms (imiquimod: 24/42 (57%) versus cidofovir: 27/41 (66%), χ2 = 0.665, P = 0.415), with no grade 4+.

CONCLUSIONS

Long-term data indicates a trend towards response being maintained for longer following treatment with cidofovir than with imiquimod, with similar low rates of adverse events for each drug. Adverse event rates indicated acceptable safety of both drugs TWEETABLE ABSTRACT: Long-term follow up in the RT3VIN trial suggests cidofovir may maintain response for longer than imiquimod.

Comparison of late adverse events after endoscopic sphincterotomy versus endoscopic papillary large balloon dilation for common bile duct stones: A propensity score-based cohort analysis

BACKGROUND AND AIM

Endoscopic sphincterotomy (ES) is a standard procedure for the treatment of common bile duct stones (CBDS). Endoscopic papillary large balloon dilation (EPLBD) is emerging as an effective method to treat difficult CBDS, providing several advantages over ES without increasing early adverse events (AE). However, the late AE of EPLBD have not yet been well studied. The aim of the present study was to compare late AE after EPLBD versus ES for the treatment of CBDS using a propensity score-based cohort analysis.

METHODS

Propensity score matching was introduced to reduce the possible bias in baseline characteristics between two treatment groups and formed the matched cohort including 240 patients. Primary endpoint was cumulative as well as estimated 1-year and 3-year late AE rates. Secondary outcome was the incidence of early AE.

RESULTS

Cumulative late AE rates were 12.5% and 16.7% in the ELPBD and ES groups (P = 0.936) with a median follow-up period of 915.5 and 1544.5 days, respectively. Estimated 1-year and 3-year late AE rates were 8.4% and 13.1% in the EPLBD group and 5.0% and 15.0% in the ES group, respectively. In multivariate analysis, ≥two procedures were identified as independent risk factors for late AE. Overall early AE rate did not differ between the groups.

CONCLUSION

In the present study, late AE rate after EPLBD showed no significant difference compared with that after ES, which had a relatively long follow-up period. Therefore, EPLBD could be used for the treatment of CBDS, if CBDS are considered difficult to treat. Clinical Trial Registry: UMIN000027798.

Pediatric acute lymphoblastic leukemia: Proportion of patients who continue hospital visits

BACKGROUND

Long-term follow up in adulthood after childhood cancer therapy is particularly important because of the risk of late effects, and information on the rate of continuing hospital visits by childhood cancer survivors (CCS) is also important for the planning of studies on the risk of late effects.

METHODS

The rate of continuing hospital visits ("long-term follow up") in 1,252 cases registered in the multicenter Japan Association of Childhood Leukemia Study on Acute Lymphoblastic Leukemia (JACLS ALL-02) was investigated using data from its electronic data capture (EDC) system, including case number, date of diagnosis, date of therapy completion, date of birth, sex, survival or death, date of death, date of last outcome confirmation, and facility code. EDC entries of confirmed survival or death during the 2 years preceding the data lock represented continuing visitors, and the number of those cases, divided by the total number of cases (excluding cases of confirmation of death prior to those 2 years), was calculated as the proportion of continuing visitors (PCV).

RESULTS

The PCV for survivors of childhood acute lymphoblastic leukemia was found to decline over time from diagnosis. For subjects aged 21-29 years who were ≥9 years from diagnosis, PCV was approximately 30% overall, representing 23.5% for men and 41.8% for women, thus indicating a gender difference.

CONCLUSIONS

Further studies may be necessary to assess whether CCS who stopped visiting childhood cancer treatment facilities, actually received therapeutic intervention or appropriate screening for late effects as adults.

Marginal bone loss at implants with different surface characteristics - A 20-year follow-up of a randomized controlled clinical trial

OBJECTIVE

This report is a 20-year follow-up of a randomized controlled clinical trial evaluating the potential long-term effect of a modified implant surface on the preservation of the peri-implant marginal bone level.

MATERIAL & METHODS

In each of 51 patients and for each fixed partial denture (FPD), by randomization at least one implant installed had a non-modified turned surface and one a modified and roughened surface (TiOblast^® ). Clinical and radiological examinations were performed at various follow-up intervals. Primary outcome variables were peri-implant marginal bone level change from time of loading and proportion of implants with no bone loss at 20 years. Multilevel analysis followed by nonparametric and Pearson's Chi-Square tests were applied for statistical analysis.

RESULTS

At the 20-year follow-up, 25 patients carrying 64 implants were available for evaluation. Turned and TiOblast implants presented with a mean bone level change from the time of FDP delivery amounting to -0.41 mm (95% CI -0.84/0.02) and -0.83 mm (95% CI -1.38/-0.28) respectively (inter-group comparison p > .05). 47% of the Turned and 34% TiOblast implants (p > .05) showed no bone loss. All but one of these implants were free of bacterial plaque and inflammation as well as presented with probing pocket depths ≤5 mm at both the 5- and 20-year follow-up examinations.

CONCLUSION

It is suggested that a moderate increase of implant surface roughness has no beneficial effect on long-term preservation of the peri-implant marginal bone level.

A Rare Form of Retinal Dystrophy Caused by Hypomorphic Nonsense Mutations in CEP290

PURPOSE

To identify the gene defect and to study the clinical characteristics and natural course of disease in a family originally diagnosed with oligocone trichromacy (OT), a rare congenital cone dysfunction syndrome.

METHODS

Extensive clinical and ophthalmologic assessment was performed on two siblings with OT and long-term follow up data were analyzed. Subsequently, whole exome sequencing (WES) and Sanger sequence analysis of CEP290 was performed in the two siblings. Additionally, the identified CEP290 mutations were analyzed in persons with achromatopsia (ACHM) (n = 23) and autosomal recessive or isolated cone dystrophy (CD; n = 145).

RESULTS

In the first decade of life, the siblings were diagnosed with OT based on low visual acuity, photophobia, nystagmus, and absent cone response on electroretinography , but with normal color discrimination. Over time, the phenotype of OT evolved to a progressive degenerative disease without any CEP290-associated non-ocular features. In both siblings, two nonsense mutations (c.451C>T; p.(Arg151*) and c.4723A>T; p.(Lys1575*)) in CEP290 were found. Previously, p.(Arg151*) was demonstrated to induce nonsense-mediated alternative splicing events leading to intact open reading frames of the resulting mRNA products (p.(Leu148_Glu165del) and p.(Leu148_Lys172del)). mRNA analysis for p.(Lys1575*) confirmed a suspected hypomorphic character, as exon 36 skipping was observed in a small fraction of CEP290 mRNA, resulting in a 36 aa in-frame deletion (p.(Glu1569_Trp1604del)). No additional cases carrying these variants were identified in the ACHM and CD cohorts.

CONCLUSIONS

Compound heterozygous hypomorphic mutations in CEP290 may lead to a rare form of cone-dominated retinal dystrophy, a novel phenotype belonging to the CEP290-associated spectrum of ciliopathies. These findings provide insight into the effect of CEP290 mutations on the clinical phenotype.

Long-term follow up of hospitalized pediatric anorexia nervosa restricting type

BACKGROUND

Information on long-term follow up of childhood-onset anorexia nervosa is scarce. This study investigated long-term (>10 years) course, outcome and prognostic factors for hospitalized childhood-onset anorexia nervosa restricting type (ANR).

METHODS

Forty-one ANR girls admitted to a single regional center participated. Median age at first admission was 13.3 years (range, 8.6-15.6 years). The longitudinal clinical course was retrospectively determined for a median follow-up period of 17.1 years (range, 10.4-21.1 years). We analyzed physical, psychological, and social variables to predict partial remission (PR) and full remission (FR).

RESULTS

The completion rate of follow up >10 years was high at 97%. At final evaluation (n = 38), distribution of prognosis was as follows: FR, n = 27 (71%); PR, n = 6 (16%); and non-remission, n = 5 (13%). The cumulative ratio of PR and FR increased during the first 5-6 years, and gradually reached a plateau at around 10 years. More than 10 years after the onset, one patient eventually achieved FR, and one patient died. Seven patients were rehospitalized and two died due to suicide during the entire follow up. On multivariate analysis, family disorders/problems rating score was a significant predictor of PR and FR.

CONCLUSIONS

This study included hospitalized ANR children aged ≤15 years, the youngest cohort ever reported. Long-term prognosis is generally favorable, but the mortality rate was 5%. Careful long-term follow up >10 years is needed to evaluate outcome of childhood-onset ANR, and family therapy is important in high-risk patients with family disorders/problems.

Long-term efficacy and safety of a nitinol closure clip system for anal fistula treatment

INTRODUCTION

Treatment failure of anal fistula results in high re-occurrence rate.

MATERIAL AND METHODS

Efficacy and safety of a nitinol closure clip system (bear-claw clip) were evaluated for anal fistulae treatment in a 36-month long-term follow-up study.

RESULTS

Twenty-two patients were included. No patient had been treated with a bear-claw clip system before. All patients were fully continent before treatment. Follow-up time was 36 months (range 19-48 months). We observed a re-occurrence rate of 41% (nine patients) with presence of an active fistula. Time to recurrence was on average 6.9 months (range 3-11 months). Thirteen patients (59%) showed a complete healing of the fistula. Placed clip was removed in all patients on average after almost 5.8 months (3-12 months), in three cases the clip was left in situ. We did not observe any incontinence; one patient reported recurrent burning after defecation once the clip system was removed.

DISCUSSIONS

Clip placement is a minimally invasive sphincter-preserving procedure with minimal complications and with an acceptable recurrence rate in the long term. However, bear-claw clip placement should probably be offered patients as a treatment option before more invasive procedures with higher perioperative morbidity are taken into consideration.

Long-term follow up of pediatric immunoglobulin A nephropathy treated with tonsillectomy plus methylprednisolone pulse therapy

BACKGROUND

The aim of this study was to clarify the long-term efficacy of tonsillectomy plus methylprednisolone pulse therapy (tonsillectomy pulse therapy [TMP]) for pediatric immunoglobulin A nephropathy (IgAN). The clinical and laboratory findings as well as the prognosis for IgAN treated with TMP at long-term follow up were evaluated.

METHODS

We collected data on 33 IgAN children treated with TMP. The children were retrospectively divided into two groups. Group 1 consisted of 18 children treated with TMP as the initial therapy, and group 2 consisted of 15 children treated with TMP as rescue therapy for IgAN relapse. The clinical features, and laboratory and pathological findings, including those at first and second renal biopsy as well as at the latest follow up, were analyzed for both groups.

RESULTS

Mean urinary protein excretion, incidence of hematuria, and serum creatinine in groups 1 and 2 were all decreased significantly after TMP compared with beforehand. The percentage of glomeruli showing crescents after TMP in groups 1 and 2 was significantly lower than before TMP. At the most recent follow up, 94% of patients in group 1 and 87% in group 2 had normal urine, 6% in group 1 and 13% in group 2 had minor urinary abnormalities, and no patients in either group had active renal disease or renal insufficiency.

CONCLUSIONS

TMP is effective in ameliorating urinary abnormalities and improving the long-term outcome of pediatric IgAN both as an initial and as a rescue treatment.

Reproductive outcomes after previous cesarean scar pregnancy: Follow up of 189 women

OBJECTIVE

To investigate the reproductive and pregnancy outcomes of women after previous Cesarean Scar Pregnancy.

MATERIALS AND METHODS

From January 2009 to December 2013, a total of 214 patients with CSP received surgical evacuation treatment by means of dilation and suction evacuation and local resection of the ectopic gestational mass. A telephone follow-up was conducted every year after CSP treatment. The follow-up was ended on December 2014.

RESULTS

Twenty-five patients were lost to follow-up due to loss of contacts. The previous medical records of the remaining 189 women were reviewed. Fifty-eight women wished to give birth again. However, 48 (82.8%, 48/58) of them stopped the attempts to get pregnant because they were afraid of recurrent CSP and the high risk of uterine rupture during the subsequent pregnancy. The other 10 women spontaneously attempted to get pregnant again, among whom 6 (60%, 6/10) succeeded with the birth of 7 healthy babies. A total of 32 women conceived again, either in plan or by chance. Five women (15.6%, 5/32) experiencing recurrent CSP.

CONCLUSION

Even though our result did not necessarily represent the true recurrence rate, our study provided some evidence about the likelihood of fertility and recurrence risk for future pregnancies after previous CSP.

Long-term developmental follow-up in children with nonsyndromic craniosynostosis

OBJECT

The aim of this study was to determine the distribution of Full Scale IQ (FSIQ) by type of craniosynostosis and to verify the finding that at long-term follow-up, verbal IQ (VIQ) is significantly higher than performance IQ (PIQ) in patients with single-suture sagittal synostosis (SS) despite falling within the "average" range for intelligence. Whether this also occurs in other types of craniosynostosis and whether surgery and sex are relevant were also determined. The relationship between age at time of surgery and later IQ was ascertained.

METHODS

The data for 91 children with craniosynostosis (47 sagittal, 15 unicoronal, 13 metopic, 9 multisuture, and 7 bicoronal) were collected at their routine, 10 years of age IQ assessment (mean age 123.8 months). The patients included 61 males and 30 females; 62 patients had undergone surgery and 29 had not.

RESULTS

The mean FSIQ for all types of craniosynostosis combined (96.2) fell within the average range for the general population. Some variation was evident across the different types of craniosynostosis: the SS group showed the highest FSIQs and a "normal" distribution of bandings; the other types had a higher proportion of FSIQs in the lower bandings. The data confirmed the finding that VIQ is greater than PIQ despite falling within the average range for intelligence, with a difference of 5.0 for all types of craniosynostosis combined (p = 0.001), 7.6 for the SS group (p = 0.001), and 6.9 for the unicoronal group (p = 0.029). This VIQ > PIQ effect was not found with multisuture craniosynostosis. The VIQ > PIQ discrepancy occurred regardless of whether the patient had undergone surgery and occurred more often in males than females. In the SS group and the bicoronal group, FSIQ (p = 0.036 and p = 0.046, respectively) and PIQ (p = 0.012 and p = 0.017, respectively), though not VIQ, were higher when surgery had been performed early.

CONCLUSIONS

The study confirms that at long-term follow-up, although children with nonsyndromic craniosynostosis fall within the normal range for intelligence, there is a VIQ > PIQ discrepancy above what would be expected in the normal population, which may be indicative of more subtle difficulties in achievement. This discrepancy is affected by type of craniosynostosis, sex, and age at time of surgery.

Giant Cell Tumor of the Talus: 19-Year Follow-Up of a Patient

Giant cell tumor in small bones is a rare condition characterized by extensive bony destruction and a high recurrence rate. Intralesional excision with curettage and autologous bone grafting has been used as a standard treatment method for giant cell tumor of the bones. We report the case of a 30-year-old female with giant cell tumor of the talar body. She was followed up for 19 years after intralesional curettage and autologous bone grafting treatment.

Extracorporeal membrane oxygenation: experience in acute graft failure after heart transplantation

INTRODUCTION

Acute graft failure is the leading cause of early mortality after heart transplantation (HTx). Extracorporeal membrane oxygenation (ECMO) is an efficient therapeutic option to treat various pathologies, unburden the left and right ventricle, and allow for functional recovery of the transplanted heart. We reviewed our ECMO experience and outcomes in HTx patients.

METHODS

Retrospectively, we analyzed all patients who received an orthotopic HTx (n = 298) in our department over a 15-yr period (1997 through 2011) to assess the incidence of post-HTx ECMO implantation, perioperative complications, early and one-yr mortality as well as causes of death.

RESULTS

ECMO therapy was utilized to treat graft failure in 28 patients (10.6%) with a mean duration of ECMO support of 4.2 d (six h to 9.4 d). Multivariate analysis revealed as independent predictors for mortality low cardiac output (p = 0.028; odds ratio (OR) = 11.3) and stroke (p = 0.008; OR = 19.7). Cumulative survival rates were 46.4 ± 9.4% within 30 d and 25.0 ± 8.2% at one yr. Causes of death were multiorgan failure (n = 9), sepsis (n = 9), lung failure (n = 2), and intracerebral bleeding (n = 2). ECMO was implanted due to primary graft failure (PGF, n = 16), sepsis (n = 4), and right heart failure (n = 6).

CONCLUSION

Temporary ECMO support for postoperative output failure is an acceptable option as a last resort for otherwise doomed patients with fatal graft failure after HTx. The small fraction of patients surviving appear to have a decent long-term prognosis.

Long-term follow up of couples initially randomized between immobilization and immediate mobilization subsequent to IUI

A previous randomized clinical trial compared immobilization for 15 min with immediate mobilization subsequent to intrauterine insemination (IUI) and showed higher ongoing pregnancy rates in couples immobilizing subsequent to IUI. The current study compared the long-term effectiveness of immobilization subsequent to IUI. All couples (n = 391) included in the trial were followed for 3 years after randomization and pregnancies and treatments were recorded. After the initial trial period, couples in both groups were offered treatment according to local protocol. The primary outcome was an ongoing pregnancy during the 3 years after the initial trial. In this time period, there were 143 ongoing pregnancies in the immobilization group (n = 199 couples) and 112 ongoing pregnancies in the immediate mobilization group (n = 192). The ongoing pregnancy rates were 72% and 58%, respectively (relative risk 1.2, 95% CI 1.1-1.4). The persistent significant difference in ongoing pregnancy rates underpins the importance of immobilization after IUI. There is no valid reason to withhold women from immobilizing for 15 min after IUI.

Predicting 10-year quality-of-life outcomes of patients with schizophrenia and schizoaffective disorders

AIMS

This study aimed to determine predictors for 10-year good versus poor perceived general quality of life (QOL) outcomes from baseline variables in people with schizophrenia and schizoaffective disorder.

METHODS

We compared patients with poor versus good 10-year QOL outcomes using baseline clinical, personality-related variables, demographic and background characteristics. Logistic regression analysis was used for predicting the 10-year QOL outcomes from baseline data. One-hundred-eight patients completed the Quality-of-Life Enjoyment and Life Satisfaction Questionnaire, the Positive and Negative Syndromes Scale (PANSS), the Talbieh Brief Distress Inventory, and psychosocial questionnaires at baseline and 10 years later.

RESULTS

Logistic regression revealed six predictors of QOL outcomes: paranoid ideations (odds ratio [OR] 3.1), PANSS general psychopathology (OR 1.1), obsessiveness (OR 0.84), hostility (OR 0.4), PANSS positive scale scores (OR 0.4), and general QOL index (OR 0.4). This model classified 80.6% of the sample with good sensitivity (87% correctly identified 'poor outcome'), and specificity (71% correctly identified 'good outcome').

CONCLUSION

This study provides a pattern of baseline predictors for long-term QOL outcomes. Identified predictors are factors that can potentially be ameliorated, and thereby enhance the QOL of people with schizophrenia and schizoaffective disorder.

Microwave endometrial ablation versus thermal balloon endometrial ablation (MEATBall): 5-year follow up of a randomised controlled trial

OBJECTIVE

To compare long-term outcomes following microwave endometrial ablation (MEA™) and thermal balloon ablation (TBall).

DESIGN

Follow up of a prospective, double-blind randomised controlled trial at 5 years.

SETTING

A teaching hospital in the UK.

POPULATION

A total of 320 women eligible for and requesting endometrial ablation.

METHODS

Eligible women were randomised in a 1:1 ratio to undergo MEA or Tball. Postal questionnaires were sent to participants at a minimum of 5 years postoperatively to determine satisfaction with outcome, menstrual status, bleeding scores and quality of life measurement. Subsequent surgery was ascertained from the women and the hospital operative database.

MAIN OUTCOME MEASURES

The primary outcome measure was overall satisfaction with treatment. Secondary outcomes included evaluation of menstrual loss, change in quality of life scores and subsequent surgery.

RESULTS

Of the women originally randomised 217/314 (69.1%) returned questionnaires. Nonresponders were assumed to be treatment failures for data analysis. The primary outcome of satisfaction was similar in both groups (58% for MEA™ versus 53% for TBall, difference 5%; 95% CI -6 to 16%). Amenorrhoea rates were high following both techniques (51% versus 45%, difference 6%; 95% CI -5 to 17%). There was no significant difference in the hysterectomy rates between the two arms (9% versus 7%, difference 2%; 95% CI -5 to 9%).

CONCLUSIONS

At 5 years post-treatment there were no significant clinical differences in patient satisfaction, menstrual status, quality of life scores or hysterectomy rates between MEA™ and Thermachoice 3, thermal balloon ablation.

Impact of exposure to interferon beta-1a on outcomes in patients with relapsing-remitting multiple sclerosis: exploratory analyses from the PRISMS long-term follow-up study

OBJECTIVE

To explore the effects of exposure to subcutaneous (sc) interferon (IFN) beta-1a on efficacy in patients with relapsing-remitting multiple sclerosis (RRMS) enrolled in the PRISMS (Prevention of Relapses and disability by Interferon beta-1a Subcutaneously in Multiple Sclerosis) study.

METHODS

Patients with RRMS received IFN beta-1a, 44 or 22 µg sc three times weekly (tiw), or placebo, for 2 years, at which point placebo recipients were re-randomized to IFN beta-1a, 44 or 22 µg sc tiw, for a further 2-4 years. Long-term follow-up visits occurred 7-8 years after enrolment and allowed participation of patients who had previously discontinued treatment. Post hoc descriptive analyses were conducted within the lower (MIN) and upper (MAX) quartiles of patients divided according to cumulative dose of IFN beta-1a and cumulative time on treatment. Outcomes were explored in patients initially randomized to IFN beta-1a, 44 µg sc tiw, who had received continuous or noncontinuous therapy during the study.

RESULTS

For both cumulative dose and time analyses, the MIN and MAX groups comprised 96 and 95 patients, respectively. The continuous and noncontinuous groups included 45 and 91 patients, respectively. The MAX DOSE and MAX TIME groups had lower annualized relapse rates, lower rates of conversion to secondary progressive MS, lower percentages of patients with Expanded Disability Status Scale progression, higher percentages of relapse-free patients, and less T2 burden of disease than the MIN groups. The continuous therapy group had a lower annualized relapse rate and lower percentages of patients with Expanded Disability Status Scale progression or conversion to secondary progressive MS than the noncontinuous therapy group.

CONCLUSIONS

The findings of these post hoc analyses suggest that high exposure to sc IFN beta-1a may be associated with better clinical outcomes than low exposure, and also highlight the importance of maximizing adherence. Additional prospective investigation is warranted to evaluate further the effects of treatment exposure on outcomes and to determine the benefits of interventions to improve adherence.
