Time-restricted eating and supervised exercise for improving hepatic steatosis and cardiometabolic health in adults with obesity: protocol for the TEMPUS randomised controlled trial.

INTRODUCTION: Metabolic dysfunction-associated steatotic liver disease is a major public health problem considering its high prevalence and its strong association with extrahepatic diseases. Implementing strategies based on an intermittent fasting approach and supervised exercise may mitigate the risks. This study aims to investigate the effects of a 12-week time-restricted eating (TRE) intervention combined with a supervised exercise intervention, compared with TRE or supervised exercise alone and with a usual-care control group, on hepatic fat (primary outcome) and cardiometabolic health (secondary outcomes) in adults with obesity. METHODS AND ANALYSIS: An anticipated 184 adults with obesity (50% women) will be recruited from Granada (south of Spain) for this parallel-group, randomised controlled trial (TEMPUS). Participants will be randomly designated to usual care, TRE alone, supervised exercise alone or TRE combined with supervised exercise, using a parallel design with a 1:1:1:1 allocation ratio. The TRE and TRE combined with supervised exercise groups will select an 8-hour eating window before the intervention and will maintain it over the intervention. The exercise alone and TRE combined with exercise groups will perform 24 sessions (2 sessions per week+walking intervention) of supervised exercise combining resistance and aerobic high-intensity interval training. All participants will receive nutritional counselling throughout the intervention. The primary outcome is change from baseline to 12 weeks in hepatic fat; secondary outcomes include measures of cardiometabolic health. ETHICS AND DISSEMINATION: This study was approved by Granada Provincial Research Ethics Committee (CEI Granada-0365-N-23). All participants will be asked to provide written informed consent. The findings will be disseminated in scientific journals and at international scientific conferences. TRIAL REGISTRATION NUMBER: NCT05897073.

Endovascular treatment of type 3 and 4 thoracic central vein obstruction in hemodialysis patients.

OBJECTIVE: Thoracic central vein (TCV) obstruction (TCVO) in the presence of upper extremity (UE) hemodialysis access can present as superior vena cava syndrome (SVCS) and cause vascular access dysfunction and failure. We report the techniques and results of endorevascularization of TCVO in hemodialysis patients, which allowed for long-term functioning vascular access in the UE. METHODS: From June 2009 to February 2020, 45 hemodialysis patients underwent TCV endorevascularization. The indications for surgery were TCVO or SVCS that threatened the function of a preexisting upper arm access or contraindicated placement of a new upper arm access. Conventional endovascular techniques were used when feasible. Patients with unfavorable anatomy were treated using a transseptal needle to cross difficult intrathoracic stenosis and occlusions or to facilitate an inside-out central venous access technique. The reestablishment of venous outflow was accomplished with angioplasty, stenting, and/or placement of HeRO conduits. Successful revascularization was followed by hemodialysis access revision or a new UE access placement. We recorded the risk factors and procedural outcomes, patency rates, complications, and mortality. RESULTS: The mean age was 53 ± 16.3 years, and 51% were women. The most common risk factors were diabetes mellitus (64.2%) and hypertension (56%). Twenty-five patients (55.5%) had symptoms of SVCS. These symptoms resolved after the TCV procedure in all cases. Crossing of the TCV lesion was successful using a conventional catheter and wire in 26 cases (57.8%) and transseptal needle in 17 cases (37.8%), including 12 using an inside-out central venous access technique. Treatment of the TCV lesion included a HeRO conduit in 20 cases (44.4%), stenting in 17 (37.7%), and transluminal balloon angioplasty alone in 7 (15.5%). Other veins were treated in 33 cases (73.3%). The overall technical success rate was 95.5%. Two intraoperative complications occurred, including one case of severe hypotension and one of fatal cardiac tamponade. Of the 16 patients with preexisting UE access, its function was preserved in all 16 (100%). In 24 of 27 patients (85.7%), new arm access was successfully created after the TCV procedure. The overall clinical success rate was 88.9%. The average follow-up was 663.4 days (median, 507 days; range, 0-2679 days). During follow-up, 26 patients had undergone 90 procedures to maintain access function, 21 had undergone repeat endovascular interventions, and 17 had undergone open procedures. Eight patients (17.8%) had developed infection, five involving HeRO conduits that required excision with loss of access. During the follow-up period, 14 patients (31%) had died of unrelated causes, and 34 patients (75.5%) maintained functional access. CONCLUSIONS: The results of the present study have shown that endorevascularization of TCVO reconstruction is effective in maintaining function or allowing the creation of UE hemodialysis access, with acceptable complication rates.

Evaluation of a New Immunochromatographic Test Using Recombinant Antigen B8/1 for Diagnosis of Cystic Echinococcosis.

Diagnosis of cystic echinococcosis (CE) is based on the identification of the cyst(s) by imaging, using immunodiagnostic tests mainly as complementary tools in clinical settings. Among the antigens used for immunodiagnosis, previous studies described a good performance of the recombinant antigen B8/1 (rAgB) in an enzyme-linked immunosorbent assay (ELISA) format; however, in remote parts of areas where the disease is endemic, the implementation of an ELISA is difficult, so a more simple, rapid, and reliable method such as the immunochromatographic test (ICT) is required. In this study, using a set of 50 serum samples from patients with surgically confirmed CE, we compared the performance of an ICT and that of an ELISA using the rAgB. The overall sensitivities of ICT and ELISA were not statistically different (78% versus 72%; P = 0.36). The overall agreement between both tests was moderate (κ = 0.41; P < 0.01). Concordance between ICT and ELISA was substantial or almost perfect for patients with liver involvement (κ = 0.65; P < 0.001) and patients with more than one hydatid cyst (κ = 0.82; P < 0.001), respectively. Moreover, specificity analysis using a total of 88 serum samples from healthy individuals (n = 20) and patients (n = 68) with other parasitic infections revealed that ICT had a specificity of 89.8%. ICT and ELISA had similar performance for the detection of specific antibodies to E. granulosus, and ICT had a high specificity, opening the possibility of using ICT as a screening tool in rural settings.

Intravenous immunoglobulin therapy for refractory recurrent pericarditis.

Recurrent pericarditis is a troublesome complication of idiopathic acute pericarditis and occurs more frequently in pediatric patients after cardiac surgery (postpericardiotomy syndrome). Conventional treatment with nonsteroidal antiinflammatory drugs, corticosteroids, and colchicine is not always effective or may cause serious adverse effects. There is no consensus, however, on how to proceed in those patients whose disease is refractory to conventional therapy. In such cases, human intravenous immunoglobulin, immunosuppressive drugs, and biological agents have been used. In this report we describe 2 patients with refractory recurrent pericarditis after cardiac surgery who were successfully treated with 3 and 5 monthly high-dose (2 g/kg) intravenous immunoglobulin until resolution of the effusion. Our experience supports the effectiveness and safety of this therapy.

[Surgical treatment for left-sided heart valve disease in a national reference hospital in Lima, Peru]. / Tratamiento quirúrgico de la enfermedad valvular cardiaca de predominio izquierdo, en un hospital de referencia nacional de Lima, Perú

OBJECTIVES: To describe the preoperative, intraoperative and postoperative characteristics of patients with left-sided heart valve disease treated in the thoracic and cardiovascular surgery service of a national reference hospital; as well as to describe the occurrence of thromboembolic and bleeding events in these patients. MATERIALS AND METHODS: A retrospective longitudinal study was carried out, which included 185 patients who underwert surgery between 1999 and 2006 at the Hospital Nacional Dos de Mayo (Lima, Peru). The patients were divided into 4 groups: patients with mitral commissurotomy; with aortic valve replacement; with mitral valve replacement and with double valve replacement. T-student test, Chi-square test, analysis of variance and Bonferroni test were used. The survival analysis took into account the severe thromboembolic and bleeding events and a follow-up period of 7 years was set. RESULTS: The average durations of disease was 4.6 years. The most frequent etiology was rheumatic valve disease (74.6%). Hospital mortality was 3.8%, the most frequent cause of death was low cardiac output syndrome associated to multiple organ failure. The incidence of ischemic events (thrombosis or embolization) in patients who had a long-term valve replacement (more than 6 months) was 3.2%, and the incidence of bleeding events was 4.3%. CONCLUSIONS: The results of surgical treatment for left-sided heart valve disease in Peru are favorable. The rate of complications and hospital mortality rate, as well as the long-term thromboembolic and bleeding events are comparable to those reported in the world literature.

Objective. To describe the surgical, clinical and epidemiological characteristics in patients with pulmonary hydatid in the Hospital Nacional Dos de Mayo. Material and methods. Descriptive, retrospective and observational study. The studied population was patients with thediagnosis of pulmonary hydatid, operated and registered in the Program of Torax and Cardiovascular Surgery of the Hospital Nacional Dos deMayo from January 2003 to December 2005. 113 clinical records and surgical reports were reviewed; clinical, epidemiological and surgicalcharacteristics, intraoperatory and postoperatory morbidity/mortality as well as six-month follow up after the surgical treatment were recorded. Results. 113 patients were enrolled, 50.4 per cent female, 15.9 per cent were from Lima Metropolitana and the main symptom was thoracic pain. The principal surgical approach was the posterolateral toracotomy (97.3 per cent). The surgical techniques used were pulmonary resection (52.2 per cent), preservative surgery (40.7 per cent) and mixed technique (7.1 per cent). Pulmonary hydatidosis with intrapulmonary involvement was presentin 4.5 per cent and extrapulmonary involvement in 25.7 per cent. Complicated cysts were in 80.5 per cent of cases. There were intraoperatives surgical complications in 73.4 per cent and postoperative complications in 22.1 per cent. Conclusions. Patients were young adults, mainly rural immmigrants or people in transit, frequently with risk factors for hydatid. Intra-operatory complications were more frequent and unusual than postoperatory complications, but had no impact on the patientsÆ mortality.

Severe mitral regurgitation and hepatopulmonary hydatid cysts: what should be treated first?

Hydatid cyst can simultaneously affect the liver and lung. Some patients might have additional comorbidities that can make management more challenging. Here, we present a 10-year-old boy with hepatopulmonary hydatid cysts and severe mitral regurgitation, who was successfully managed with a staged surgical approach treating the lung first, followed by the liver and finally, the heart.

Surgical management of Aspergillus colonization associated with lung hydatid disease.

Colonization with Aspergillus sp. usually occurs in previously formed lung cavities. Cystectomy is a widely used surgical technique for hydatid lung disease that can also leave residual cavities and potentially result in aspergilloma. We present two cases of this rare entity and a case with Aspergillus sp. colonization of an existing ruptured hydatid cyst.
