Malnutrition in hospitalized cancer patients: A single-center, cross-sectional study in Southern Vietnam.

Objectives: Malnutrition in cancer patients reduces response to chemotherapy, increases the hospitalization costs, hospital infections, and deaths. The aim of this study was to determine the prevalence, level of malnutrition, and its related factors in cancer patients at a local hospital in Southern Vietnam. Methods: A descriptive cross-sectional study was performed on all 118 cancer patients who were undergoing inpatient treatment at Long An General Hospital, Vietnam from May to September 2020. Data were collected from patients by face-to-face interviewing using a subjective global assessment (SGA) and from medical records. Malnutrition is divided into three groups: SGA-A (normal), SGA-B (mild/moderate/suspected malnutrition), SGA-C (severe malnutrition). Multivariable logistic regression is used to identify factors related to malnutrition with statistical significance p < 0.05. Results: Out of 118 participants, 72 (61.0%) were males and 84 (71.2%) aged ⩾60 years. The prevalence of malnutrition in cancer patients was 84.7% (100/118), in which 33% (39/118) were severe (SGA-C) and 51.7% (61/118) were mild-moderate (SGA-B). Pancreatic and lung cancers are the most malnourished. The results of multivariate logistic regression analysis showed that the factors related to malnutrition in cancer patients were gastrointestinal symptoms lasting 2 weeks (odds ratio: 6.10, 95% confidence interval: 1.12-33.35), patients with decreased motor function (odds ratio: 13.73, 95% confidence interval: 2.56-73.86), blood albumin <35 g/l (odds ratio: 6.42, 95% confidence interval: 1.54-26.82), and blood lymphocyte ⩽ 1700 cells/mm3 (odds ratio: 5.36, 95% confidence interval: 1.31-21.97). Conclusions: There was a high proportion of malnutrition in cancer patients. Therefore, it is necessary to strengthen nutrition counseling and intervention for these patients, especially those that have prolonged gastrointestinal symptoms, reduced motor function, and low blood albumin or low blood lymphocytes.

Percutaneous aspiration and absolute ethanol sclerotherapy in the treatment of symptomatic bronchogenic cyst.

Surgical treatment is indicated for both symptomatic and asymptomatic bronchogenic cysts. The goal of treatment is total removal of the cyst. Percutaneous aspiration and absolute ethanol sclerotherapy is an effective, minimally invasive, and safe alternative method. We present the case of a 74-year-old woman with a symptom of persistent dry cough for 5 months. Plain and contrast-enhanced chest computed tomography revealed a large superior mediastinal cyst that could be easily accessed percutaneously. The cyst was treated by aspiration and ethanol sclerotherapy under ultrasound guidance and fluoroscopy. The patient was discharged a day later without complications. Chest CT at 6 months follow-up showed complete regression of the cyst.

Traumatic rupture of the thoracic aorta: A life-threatening emergency and the role of endovascular repair.

Traumatic rupture of the thoracic aorta is a rare condition, with a high mortality rate. Over the last 2 decades, strategies for managing aortic injury caused by blunt chest trauma have changed substantially, resulting in significantly improved outcomes. The recent development of endovascular repair offers a less invasive alternative to conventional open repair, particularly in patients with multiple injuries. Here, we report the case of a 31-year-old man who was referred to our emergency department with blunt chest trauma following a motorcycle-truck collision. Computed tomography confirmed acute traumatic rupture of the thoracic aorta, and the patient was successfully treated with endovascular repair.

Catheter-directed intra-arterial thrombolysis in the treatment of acute thrombosis of below-the-knee arteries.

Selecting treatment options in acute arterial thrombosis of the lower extremity, which threatens limb viability, is still a challenge for vascular surgeons. Early restoration of blood flow is crucial and is conducted by surgical thrombectomies or endovascular procedures, depending on patient condition. Catheter-directed thrombolysis with or without percutaneous mechanical thrombectomy for acute limb ischemia has been widely implemented from the early 1990s. Here, we present 2 cases of acute thrombosis of below-the-knee arteries, where we successfully saved the involved limbs using catheter-directed thrombolysis and thrombus aspiration.

Long-term outcomes of video-assisted lobectomy in non-small cell lung cancer.

BACKGROUND: Video-assisted thoracoscopic surgery lobectomy combined with lymphadenectomy is widely utilized worldwide for treating non-small cell lung cancer. We evaluated the long-term survival outcomes of this approach and determined the prognostic factors of overall survival. METHODS: This prospective observational study was performed in patients with non-small cell lung cancer who were subjected to video-assisted lobectomy and lymphadenectomy from 2012 to 2016. Independent prognostic factors were determined via uni- and multivariable Cox models. RESULTS: There were 109 patients with the mean age of 59.2 years and males accounted for 54.1%. Postoperative staging determined 22.9% of stage IA, 31.2% of stage IB, 16.5% of stage IIA and 29.4% of stage IIIA. Median follow-up time was 27 months. The overall survival rate after 1, 2, 3, 4 and 5 years was 100%, 85.9%, 65.3%, 55.9% and 55.9%, respectively. In univariable analysis, smoking (hazard ratio (HR) [95% confidence interval (CI)]: 2.50 [1.18-5.31]), Tumor--nodes--metastases (TNM) stage (IIA: 7.60 [1.57-36.9]; IIIA: 14.3 [3.28-62.7] compared to IA), histological differentiation (moderately differentiated: 4.91 [1.04-23.2]; poorly differentiated: 8.25 [1.91-35.6] compared to well differentiated), lymph node size ≥1 cm (8.22 [3.11-21.7]), tumour size ≥3 cm (4.24 [1.01-17.9]), radical lymphadenectomy (6.67 [3.14-14.2]) were identified as prognostic factors of the long-term survival. In multivariable analysis, only radical lymphadenectomy was an independent prognostic factor (HR [95% CI]: 3.94 [1.41-11.0]). CONCLUSION: Video-assisted thoracoscopic lobectomy combined with lymphadenectomy is feasible, safe and effective for the treatment of non-small cell lung cancer. The long-term outcomes of this method are favourable, especially at the early stage of cancer.

Endovascular repair for abdominal aortic aneurysm in a kidney transplant recipient.

Surgical treatment of abdominal aortic aneurysm in patients with a transplanted kidney is true a challenge. Conventional open repair of the aneurysm requires aortic cross-clamping. Therefore, it can pose a risk of ischemic injury to the transplanted kidney. Endovascular repair, which limits the duration of interruption of blood flow to the transplanted kidney, is a suitable alternative for repair of abdominal aortic aneurysm, if feasible anatomically. Here, we present a case of a 62-year-old woman who was transferred to our hospital because of abdominal pain and had a history of renal transplant 14 years ago. Computed tomography confirmed a large infrarenal fusiform abdominal aortic aneurysm 6 cm in maximal diameter and another 4 cm fusiform aneurysm in the left common iliac artery. We successfully performed endovascular aneurysm repair combined with femoro-femoral bypass. The postoperative course was uneventful, and the patient was discharged on the 5th postoperative day.

Imaging findings of three cases of large mediastinal mature cystic teratoma.

Mature cystic teratoma (MCT) is a benign, slow-growing tumor and accounts for approximately 75% of mediastinal germ cell tumors. Patients with MCT are often asymptomatic when the tumors are small. Most of the symptoms are frequently related to compression of the mediastinal structures. We herein describe 3 adult cases of MCT. The patients were a 37-year-old man, a 35-year-old woman, and a 54-year-old woman. They were hospitalized with compression-related symptoms, such as chest pain, dyspnea, and cough. Findings from conventional chest radiograph, computed tomography (CT), magnetic resonance imaging were characterized. Conventional chest radiography still plays a major role in the initial evaluation of MCT, while CT remains the preferred modality for initial cross-sectional imaging evaluation of mediastinal lesions. However, thoracic magnetic resonance imaging provides more detailed and often definitive evaluation of mediastinal masses than CT because of its superior tissue characterization.

Simultaneous endovascular repair for abdominal aortic aneurysm and coronary artery bypass grafting in an octogenarian: A case report.

INTRODUCTION: Coronary artery disease (CAD) is commonly associated with abdominal aortic aneurysms (AAAs) in elderly patients. When severe CAD requiring coronary artery bypass grafting (CABG) is associated with an impending AAA in a high-risk patient, the options for the suitable timing of CABG and AAA repair strategy (one-stage or two-stage) are still being debated. PRESENTATION OF CASE: An 87-year-old man with non-ST-segment elevation myocardial infarction and a giant abdominal aortic aneurysm was transferred to our centre. Coronary angiography revealed triple-vessel coronary disease, and computed tomography confirmed a giant infrarenal fusiform abdominal aortic aneurysm 9 cm in maximal diameter. We simultaneously performed endovascular aneurysm repair prior to on-pump beating-heart coronary artery bypass grafting. The postoperative course was uneventful, and the patient was discharged on the 15th postoperative day. CONCLUSION: Combined endovascular aneurysm repair and on-pump beating heart coronary artery bypass grafting in a one-stage operation is a promising strategy to improve therapeutic efficiency in octogenarians. More studies are needed to compare the efficacy and safety of one-stage and two-stage operations to treat concomitant coronary artery disease and aortovascular pathology in the high-risk octogenarian patients.

Surgical treatment of acute aortic dissection Stanford type A in the third trimester of pregnancy: A case report.

BACKGROUND: Aortic dissection is rare in pregnancy, but it is often life-threatening. Thus, early diagnosis and optimal treatment are crucial. In addition, regular multidisciplinary care plays an important role in improving the therapeutic outcome. CASE: A 31-year-old pregnant woman (gravida 2, para 1, abortus 0) was transferred to our centre at 34 weeks of gestation with onset of dyspnoea and serious chest pain radiating to her back. Ultrasonography unexpectedly revealed a dilation of the aortic root with a sign of dissection. Computed tomography confirmed a type A aortic dissection based on the Stanford classification. She was successfully treated by caesarean section prior to open repair of acute type A dissection and received multidisciplinary care. The patient was discharged on the 16th postoperative day, and the baby is still alive without adverse events. CONCLUSION: Aortic dissection in pregnancy is relatively rare, but physicians should be on high alert for the condition when a pregnant woman has chest pain. Early diagnosis and adequate treatment in addition to regular multidisciplinary care are crucial to achieve favourable results.

Radiofrequency Ablation for Benign Thyroid Nodules: 1-Year Follow-Up in 184 Patients.

BACKGROUND: Benign thyroid nodules are common, and must be treated when symptomatic. Non-surgical minimally invasive modalities, including radiofrequency ablation (RFA), have been widely used with good results. The factors related to the efficacy of RFA are still debated. This study was to evaluate the safety, efficacy and related factors of RFA in the treatment of benign thyroid nodules. METHODS: A retrospective single-center study was conducted on 251 benign thyroid nodules in 184 patients treated with RFA. The procedure was performed under ultrasound (US) guidance using the trans-isthmic approach and the moving-shot technique. Clinical and US examinations were performed at 1, 3, 6, 12 months, and then at 6 month intervals. Study outcomes were volume reduction ratio (VRR) and complications. RESULTS: There were 153 women and 31 men included in the study. The mean age was 43.9 years. The median initial largest diameter and volume of nodules were 30 mm and 6.18 ml. The median length of follow-up was 12 months. Two minor complications were found. The mean VRR was 66.8; 74.3; and 81% after 3, 6, and 12 months, respectively. Initial solidity was a factor related to the efficacy: cystic nodules had higher VRR compared to solid ones. CONCLUSIONS: RFA is safe, effective and can be used as a routine treatment for benign thyroid nodules. More prospective multicenter studies with long-term follow-up are required to improve the safety and efficacy of RFA.
