Health-state utility of patients with HER2-positive breast cancer in Vietnam: A multicenter cross-sectional study.

BACKGROUND: Patients with human epidermal growth factor receptor 2 (HER2)-positive breast cancer may have poor prognoses and short overall and disease-free survival. Most previous studies focused on assessing the quality of life and health-state utility of the general population of breast cancer patients. The number of studies for HER2-positive breast cancer patients is negligible. This study investigated the health-state utility and its associated factors among Vietnamese patients with HER2-positive breast cancer. METHODS: We conducted face-to-face interviews with 301 HER2-positive breast cancer patients to collect data. Their health-state utility was measured via the EQ-5D-5L instrument. The Mann-Whitney U and Kruskal-Wallis tests were employed to compare the differences in utility scores between two groups and among three groups or more, respectively. Factors associated with patients' heath-state utility were identified via Tobit regression models. RESULTS: Pain/discomfort (56.1%) and anxiety/depression (39.5%) were the two issues that patients suffered from the most, especially among metastatic breast cancer patients. The severity of distress (depression, anxiety, and stress) in patients was relatively mild. Of 301 patients, their average utility score was 0.86±0.17 (range: 0.03-1.00), and the average EQ-visual analogue scale (VAS) score was 69.12±12.60 (range: 30-100). These figures were 0.79±0.21 and 65.20±13.20 for 102 metastatic breast cancer patients, significantly lower than those of 199 non-metastatic cancer patients (0.89±0.13 and 71.13±11.78) (p<0.001), respectively. Lower health-state utility scores were significantly associated with older age (p = 0.002), lower education level (p = 0.006), lower monthly income (p = 0.036), metastatic cancer (p = 0.001), lower EQ-VAS score (p<0.001), and more severe level of distress (p<0.001). CONCLUSIONS: Our findings showed a significant decrement in utility scores among metastatic breast cancer patients. Patients' health-state utility differed by their demographic characteristics (age, education level, and income) and clinical characteristics (stage of cancer and distress). Their utility scores may support further cost-effectiveness analysis in Vietnam.

Cost-effectiveness of rimegepant oral lyophilisate compared to best supportive care for the acute treatment of migraine in the UK.

AIMS: Migraine is the most common disabling headache disorder and is characterized by recurrent throbbing head pain and symptoms of photophobia, phonophobia, nausea, and vomiting. Rimegepant 75 mg, an oral lyophilisate calcitonin gene-related peptide antagonist, is the first treatment approved for both the acute and preventative treatment of migraine, and the first acute therapy approved in over 20-years. The objective was to assess the cost-utility of rimegepant compared with best supportive care (BSC) in the UK, for the acute treatment of migraine in the adults with inadequate symptom relief after taking at least 2 triptans, or for whom triptans are contraindicated or not tolerated. MATERIALS AND METHODS: A de novo model was developed to estimate incremental costs and quality-adjusted life years (QALYs), structured as a decision tree followed by Markov model. Patients received rimegepant or BSC for a migraine attack and were assessed for response (pain relief at 2-h). Responders and non-responders followed different pain trajectories over 48-h cycles. Non-responders discontinued treatment while responders continued treatment for subsequent attacks, with a proportion discontinuing over time. Data sources included a post-hoc pooled analysis of the phase 3 acute rimegepant trials (NCT03235479, NCT03237845, NCT03461757), and a long-term safety study (NCT03266588). The analysis was conducted from the perspective of the UK National Health Service and Personal Social Services over a 20-year time horizon. RESULTS: Rimegepant resulted in an incremental cost-utility ratio (ICUR) of £10,309 per QALY gained vs BSC, which is cost-effectiveness at a willingness to pay threshold of £30,000/QALY. Rimegepant generated +0.44 incremental QALYs and higher incremental lifetime costs (£4,492). Improved QALYs for rimegepant were a result of less time spent with severe and moderate headache pain. CONCLUSION: This study highlights the economic value of rimegepant which was found to be cost-effective for the acute treatment of migraine in adults unsuitable for triptans.

Determining the factors impacting the quality of life among the general population in coastal communities in central Vietnam.

People living in coastal areas are frequently affected by natural disasters, such as floods and storms. This study aimed to assess the quality of life (QoL) of people living in disadvantaged coastal communes (subdivision of Vietnam) and identify their associated factors by using the World Health Organization's quality of life instrument (WHOQOL-BREF). To achieve this, a cross-sectional descriptive study was conducted on 595 individuals aged 18 years and above living in the coastal communes in Thua Thien Hue province, Vietnam, from October 2022 to February 2023. The results showed that the mean overall QoL (mean ± SD) was 61.1 ± 10.8. Among the four domains of QoL, the physical health (57.2 ± 12.3) domain had a lower score than the psychological health (61.9 ± 13.0), social relations (63.4 ± 13.4), and environment (61.9 ± 13.3) domains. The QoL score of the domains for participants affected by flooding was significantly lower than that of those not affected, except for social relations. Multivariable logistic regression showed that subjects with not good QoL had the educational background with no formal education (Odds ratio (OR) = 2.63, 95% CI 1.19-5.83), fairly poor/poor households (OR = 2.75, 95% CI 1.48-5.12), suffered Musculoskeletal diseases (OR = 1.61, 95% CI 1.02-2.56), unsatisfaction with health status (OR = 5.27, 95% CI 2.44-11.37), family conflicts (OR = 4.51, 95%CI 2.10-9.69), and low levels of social support (OR = 2.62; 95% CI 1.14-6.02). The analysis also revealed that workers (OR = 0.17, 95% CI 0.04-0.66) had a better QoL than farmer-fisherman. QoL in disadvantaged coastal communes was low, with the lowest scores in the physical health domain. Based on the socioeconomic factors associated with not good QoL identified here, it is recommended that local authorities take more appropriate and practical measures to increase support, including measures for all aspects of physical health, psychological health, social relations, and the living environment, especially for people affected by floods.

Quality Control Method and Device for Producing Agarose Micropads.

In brightfield and fluorescence microscopy, capturing images that show well-focused and immobile microorganisms can be challenging. An agarose-based gel pad reduces the variability of results, especially in conditions like uneven specimen staging, variable fluid dynamics, and Brownian motion that plague conventional wet mount setups. To correct these discrepancies during image acquisition, we analyzed three micropad preparation setups. We tested the quality and consistency of pads and images resulting from each setup. Our examination reveals that improved gel pad flatness is associated with better image quality. Moreover, we observe increased consistency in gel pad construction connected to the use of a 3D-printed setup. These findings highlight the technical benefits arising from incorporating micropad-generating platforms that increase the consistency of results in imaging pipelines. Additionally, our use of a quantitative approach to examine pad flatness suggests its inclusion in quality control pipelines to reduce variation in gel pad construction and image quality over time and between investigators. Finally, our use of a 3D-printed setup coupled with a quantitative downstream routine suggests their application in microscopy experiments that involve model organisms relevant to human health and disease.

Health Care Challenges in the Management of Primary Aldosteronism in Southeast Asia.

CONTEXT: While guidelines have been formulated for the management of primary aldosteronism (PA), following these recommendations may be challenging in developing countries with limited health care access. OBJECTIVE: We aimed to assess the availability and affordability of health care resources for managing PA in the Association of Southeast Asian Nations (ASEAN) region, which includes low-middle-income countries. METHODS: We instituted a questionnaire-based survey to specialists managing PA, assessing the availability and affordability of investigations and treatment. Population and income status data were taken from the national census and registries. RESULTS: Nine ASEAN country members (48 respondents) participated. While screening with aldosterone-renin ratio is performed in all countries, confirmatory testing is routinely performed in only 6 countries due to lack of facilities and local assays, and cost constraint. Assays are locally available in only 4 countries, and some centers have a test turnaround time exceeding 3 weeks. In 7 countries (combined population of 442 million), adrenal vein sampling (AVS) is not routinely performed due to insufficient radiological facilities or trained personnel, and cost constraint. Most patients have access to adrenalectomy and medications. In 6 countries, the cost of AVS and adrenalectomy combined is more than 30% of its annual gross domestic product per capita. While most patients had access to spironolactone, it was not universally affordable. CONCLUSION: Large populations currently do not have access to the health care resources required for the optimal management of PA. Greater efforts are required to improve health care access and affordability. Future guideline revisions for PA may need to consider these limitations.

Epilepsy self-management mobile health application: A needs assessment in people with epilepsy and caregivers in Viet Nam.

OBJECTIVES: This study aimed to determine (1) the needsof Vietnamese people with epilepsy (PWE) and their caregivers for self-management mobile health applications and (2) the self-management features expected to be included in an application. METHODS: The survey consisted of an anonymous self-administered questionnaire that was distributed to PWE and caregivers from the age of 18 in Vietnam through online platforms and onsite at Nguyen Tri Phuong Hospital and University Medical Center, Ho Chi Minh City, from February 2022 to May 2022. The questionnaire assessed the participants' attitudes toward epilepsy self-management mobile applications, their willingness to use applications, and their expectations of the contents of an application. RESULTS: Responses from 103 participants were submitted. Eighty-one participants (78.6%) reported using a smartphone, but only 50.6% of those claimed to know about self-management applications. Most respondents (70.9%) thought the applications would be useful for disease self-management, and 68.9% were willing to use epilepsy self-management applications. In addition, the most expected features to be included in self-management applications were epilepsy information, seizure first aid, connecting with medical professionals, and a seizure diary. CONCLUSION: Most Vietnamese PWE and caregivers had a willingness to use epilepsy self-management applications.The expected features are related to all aspects of self-management, including information, seizure, medication, and safety management.

The antimicrobial activity and essential oil constituents of the leaves and trunks of Aquilaria banaensis P.H.Hô (Thymelaeceae) from Vietnam.

The aim of the present paper was to report the chemical constituents and antimicrobial activity of essential hydrodistilled from the leaves and trunk of Aquilaria banaensis P.H.Hô (Thymelaeceae) from Vietnam. The essential oils were analysed comprehensively for their constituents by using Gas chromatography coupled with Mass spectrometry (GC/MS). The antimicrobial activity was determined by agar well diffusion and broth microdilution methods. The leaf essential oil comprised mainly of sesquiterpenes while fatty acids constitutes the bulk of the trunk essential oil. The main constituents of the leaf essential oil were ß-caryophyllene (17.11%), α-selinene (10.99%), α-humulene (8.98%), ß-selinene (8.01%), ß-guaiol (6.69%) and ß-elemene (5.65%). However, hexadecanoic acid (48.46%), oleic acid (19.80%) and tetradecanoic acid (5.32%) were the major compounds identified in the trunk essential oil. The trunk essential oil displayed antimicrobial activity against Staphylococcus aureus, with the minimum inhibitory concentration (MIC) value of about 256.0 µg/mL.

Outcomes of laparoscopic choledochotomy using cholangioscopy via percutaneous-choledochal tube for the treatment of hepatolithiasis and choledocholithiasis: A preliminary Vietnamese study.

Backgrounds/Aims: Hepatolithiasis and choledocholithiasis are frequent pathologies and unfortunately, with the current treatment strategies, the recurrence incidence is still high. This study aimed to assess the outcomes of laparoscopic choledochotomy using cholangioscopy via the percutaneous-choledochal tube for the treatment of hepatolithiasis and choledocholithiasis in Vietnamese patients. Methods: A cross-sectional study of patients with hepatolithiasis and/or choledocholithiasis who underwent laparoscopic choledochotomy using intraoperative cholangioscopy via percutaneous-choledochal tube at the Department of Hepatopancreatobiliary Surgery, 108 Military Central Hospital, from June 2017 to March 2020. Results: A total of 84 patients were analyzed. Most patients were females (56.0%) with a median age of 55.56 years. Among them, 41.8% of patients had previous abdominal operations, with 33.4% having choledochotomy. All patients underwent successful laparoscopic common bile duct exploration followed by T-tube drainage without needing to convert to open surgery. Most patients (64.3%) had both intrahepatic and extrahepatic stones. The rate of stones ≥ 10 mm in diameter was 64.3%. Biliary strictures were observed in 19.1% of patients during cholangioscopy. Complete removal of stones was achieved in 54.8% of patients. Intraoperative complications were encountered in two patients, but there was no need to change the strategy. The mean operating time was 121.85 ± 30.47 minutes. The early postoperative complication rate was 9.6%, and all patients were managed conservatively. The residual stones were removed through the T-tube tract by subsequent choledochoscopy in 34/38 patients, so the total success rate was 95.2%. Conclusions: Laparoscopic choledochotomy combined with cholangioscopy through the percutaneous-choledochal tube is a safe and effective strategy for hepatolithiasis and/or choledocholithiasis, even in patients with a previous choledochotomy.

An Undetected Pheochromocytoma Leading to Fulminant Adrenergic Myocarditis Complicated by Cardiogenic Shock.

Pheochromocytomas are rare catecholamine-secreting neuroendocrine tumors. Their episodic nature is correlated with abrupt catecholamine release and clinical manifestations that mimic other vascular conditions, leading to delayed diagnosis and potentially life-threatening complications, such as acute myocarditis and pheochromocytoma crises. In this report, we described the case of fulminant adrenergic myocarditis-induced cardiogenic shock requiring extracorporeal membrane oxygenation support in a Vietnamese middle-aged man with a 5-year history of Brugada syndrome, hypertension, and previously undiagnosed pheochromocytoma. After stabilization, the patient was medically treated with a combination of α- and ß-blockers before undergoing laparoscopic right adrenalectomy.

Is Social Support Associated with Colorectal Cancer Care Utilization? A Multilevel Mixed-Effects Model of a Cross-Sectional Cohort Study in Vietnam.

OBJECTIVE: To investigate the relationship between the social support (SS) and colorectal cancer (CRC) care utilization of patients in the central region of Vietnam. METHODS: This was a cross-sectional cohort study in which the cohort was defined as all residential patients diagnosed with CRC in a tertiary hospital, Hue Central Hospital (HCH), in central Vietnam from 2013 to 2019. Social support was considered the main independent variable and was evaluated using the Medical Outcomes Study Social Support Survey (MOS-SSS), a self-administered 19-item SS survey. MOS-SSS is a widely used scale for assessing social support in CRC patients because it is brief, easy to use, reliable, and valid. In this study, we considered a data framework with a multilevel structure that included the patient level and duration of diagnosis as the second level. We estimated the magnitude of SS and CRC-specific treatment modalities using multilevel mixed-effects (MM) models under a hierarchical approach. RESULTS: The findings indicated that CRC care utilization rates were 89.9%, 48.5%, and 30.6% for surgical resection, chemotherapy, and radiation therapy, respectively. The overall trend of SS decreased significantly and affected the CRC care utilization. We found a positive effects of overall SS, as well as emotional and tangible support, on the number of hospitalization admissions and chemotherapy utilization. CONCLUSION: This study suggests that the use of the MOS-SSS should be continued in the long term for CRC patients to enhance medical accessibility and care utilization.

Chemical composition and antimicrobial activity of essential oil from Popowia pisocarpa (Bl.) Endl., Walp. Repert. (Annonaceae).

The volatile compositions and antimicrobial activity of aerial parts of Popowia pisocarpa from Vietnam were reported for the first time. From the GC/MS spectral, spathulenol (35.9%), bicyclogermacrene (5.7%) and muurola-4,10(14)-dien-1ß-ol (4.2%) among the sesquiterpenoids, along with 4,4-dimethyl-3-(3-methylbut-3-enylidene)-2-methylenebicyclo[4,1,0]heptane (17.7%), an unsaturated cyclic compound, were the main constituents of the essential oil. Monoterpenoids were not identified in the essential oil. The essential oil displayed antimicrobial activity against the Gram-negative Escherichia coli ATCC 25922 with MIC value of 16.0 µg/mL and IC50 value of 8.52 µg/mL. In addition, the essential oil also exhibited activity towards the Gram-positive bacteria of Staphylococcus aureus ATCC 13709, Bacillus subtilis ATCC 6633, and Lactobacillus fermentum N4 with MIC value of 64.0 µg/mL each and corresponding IC50 values of 11.06 µg/mL, 26.47 µg/mL and 15.68 µg/mL, respectively. The essential oil did not inhibit the growth of Pseudomonas aeruginosa ATCC 15442, Salmonella enterica and the yeast Candida albicans ATCC 10231.

Adjuvant chemotherapy in locally advanced rectal cancer after neo-adjuvant concurrent chemoradiotherapy and surgery: A retrospective study in Vietnamese patients.

Background: Advances in preoperative chemoradiotherapy and surgical techniques offered improvements in rates of locoregional recurrence but did not address distant metastasis. Traditionally, adjuvant chemotherapy has been administered with the goal of limiting systemic recurrences. Objective: Evaluation of the efficacy and safety of adjuvant chemotherapy in patients with locally advanced rectal cancer after preoperative chemoradiotherapy and surgery. Methods: From January 2017 to December 2018, 103 patients diagnosed with clinical stage II or III rectal cancer received adjuvant chemotherapy with capecitabine or XELOX regimens after neoadjuvant concurrent chemoradiotherapy and total mesorectal excision. Overall survival, disease-free survival, and toxicity were analyzed. Results: The median follow-up time was 52.5 months (6.5-66.8 months). The mean 3-year disease-free survival and 3-year overall survival were 86.2% (95% CI: 82.8-89.6) and 92.2% (95% CI: 86.9-97.5), respectively. The rate of hematologic and nonhematologic toxicity was low, mostly grades 1 and 2 including anemia, leucopenia, thrombocytopenia, and liver enzymes elevations were 85.4, 50.5, 42.8, and 45.6%, respectively. Conclusion: The capecitabine and XELOX regimen in adjuvant settings for rectal cancer patients receiving neoadjuvant chemoradiotherapy and surgery was a safe and effective modality. Further randomized trials need to be conducted to evaluate the role of postoperative therapy for these individuals.

Exploring Shigella vaccine priorities and preferences: Results from a mixed-methods study in low- and middle-income settings.

Background: Shigella is the leading bacterial cause of diarrheal mortality in children and can cause long-term effects on growth and development. No licensed Shigella vaccines currently exist but several promising candidates are in development and could be available in the next five years. Despite Shigella being a well-known public health target of the World Health Organization for decades, given current burden estimates and competing preventable disease priorities in low-income settings, whether the availability of an effective Shigella vaccine will lead to its prioritization and widespread introduction among countries at highest risk is unknown. Methods: We conducted a mixed-methods study of national stakeholders and healthcare providers in five countries in Asia and Africa and regional stakeholders in the Pan American Health Organization to identify preferences and priorities for forthcoming Shigella vaccines. Results: In our study of 89 individuals, diarrhea was the most frequently mentioned serious health concern for children under five years. Antimicrobial resistance (AMR) was more often considered very concerning than diarrhea or stunting. Shigella awareness was high but not considered a serious health concern by most stakeholders. Most participants were willing to consider adding a new vaccine to the routine immunization schedule but expressed reservations about a Shigella vaccine because of lower perceived burden relative to other preventable diseases and an already crowded schedule; interest was highest among national stakeholders in countries receiving more financial support for immunization. The priority of a Shigella vaccine rose when participants considered vaccine impacts on reducing stunting and AMR. Participants strongly preferred oral and combination vaccines compared to injectable and a single-antigen presentations, citing greater perceived community acceptability. Conclusions: This study provides a critical opportunity to hear directly from country and regional stakeholders about health priorities and preferences around new vaccines. These findings should inform ongoing Shigella vaccine development efforts and eventual vaccine introduction and implementation planning.

Systemic chemotherapy combined with radiofrequency ablation for colorectal cancer with liver metastasis: a retrospective cohort study.

This study aims to evaluate the efficacy of systemic chemotherapy combined with radiofrequency ablation in the treatment of inoperable colorectal cancer with liver metastasis. Materials and methods: The authors conducted a retrospective cohort analysis on 30 patients diagnosed as colorectal cancer with liver metastasis who underwent systemic chemotherapy combined with radiofrequency ablation of the liver lesions from January 2017 to August 2020 at our institution. Responses was evaluated by International Working Group on Image-guided Tumor Ablation criteria, along with progression-free survival. Results: The response rate after 4 cycles and 8 cycles of chemotherapy were 73.3% and 85.2%, respectively. All patients achieved responses after of radiofrequency therapy, with the rates of complete response and partial response were 63.3% and 36.7%. The median progression-free survival was 16.7 months. After radiotherapy ablation, all patients had mild to moderate hepatic pain, 10% of patients had fever and increased liver enzymes occurred in 90% of patients. Conclusions: Systemic chemotherapy combined with radiofrequency ablation was safe and effective in colorectal cancer with liver metastasis and warrants further large-scale studies.

Typhoid fever, complicated by syncope due to relative bradycardia: A case report.

In a United Nations (UN) staff member headquarters in South Sudan, we present a rare typhoid fever complicated by syncope due to relative bradycardia. A 25-year-old male presented to our hospital with a high fever, diarrhea, and no vomiting. He had no substantial medical background. He was diagnosed with an unspecified digestive disorder and received initial treatment. Two syncope episodes were recorded in the Level 1 hospital. He was referred to our hospital at the 30th hour and the third fainting occurred. Electrocardiogram showed bradycardia with a heart rate of 40 beats/min. The atropine test was negative; the initial diagnosis was sinus sickness syndrome. Microbiology tests later suggested typhoid infection. Then, the diagnosis changed to relative bradycardia caused by Salmonella typhi; and he was orally treated with the third-generation Quinolone antibiotic. He significantly improved and got discharged on the seventh day. In conclusion, typhoid remains a real and present threat to UN staff and civilians in South Sudan.

Chemical composition and acetylcholinesterase inhibitory activity of essential oil from the leaves of Mitrephora poilanei Weeras. & R.M.K. Saunders.

The present study provides the first information on the chemical composition and acetylcholinesterase inhibitory activity of the essential oil (EO) from the leaves of Mitrephora poilanei Weeras. & R.M.K.Saunders from Vietnam. Gas chromatography and gas chromatography-mass spectrometry analysis revealed that the main components of the M. poilanei EO were ß-caryophyllene (13.2%), α-humulene (10.5%), germacrene D (8.1%), ß-elemene (5.2%) and bicyclogermacrene (5.1%). The anti-acetylcholinesterase assay showed that the EO displayed moderate activity with IC50 value of 31.16 ± 3.06 µg/mL. These findings proposed that the plant can be exploited for its anti-acetylcholinestrate potential.

Primary gastrointestinal non-Hodgkin lymphoma: a retrospective study in Vietnam.

Although primary gastrointestinal non-Hodgkin lymphoma (GI NHL) is a rare hematopoietic malignancy, it is the most common extranodal site involved by lymphoma. Treatment methods are chosen based on many factors, including site of lesion, histopathology, symptoms, and patients' choice. Objectives: To evaluate the clinical characteristics, treatment results and prognosis for primary GI NHL in Vietnamese patients. Patients and methods: This was a retrospective descriptive study on 126 patients with primary GI NHL treated at our hospital from 2010 to 2015. Data of all patients were collected and analyzed. Results: B-cell non-Hodgkin's lymphoma was the major pathology with rate of 93.7%, in which Diffuse Large B-Cell Lymphoma type accounted for 58.7%, followed by Mucosa-associated lymphoid tissue lymphoma type 22.2%. Less common forms were cystic type, Burkitt's lymphoma, Mantle cell, T cell. The majority of patients receiving chemotherapy achieved a complete response, up to 70%. Overall survival and 5-year disease-free survival were 74.1% and 59.3%, respectively. Overall, stomach lymphoma had a longer survival rate than those in the small intestine. Factors including Eastern Cooperative Oncology Group score of 2-4, elevated Lactate Dehydrogenase levels at baseline, stage of widespread illness (III/IV), high malignancy histopathology, and lesion size of more than 10 cm were poor prognostic indicators. Conclusions: Gastric lesion was the most frequent site and has better prognosis than other locations. Other prognostic factors for overall survival included Eastern Cooperative Oncology Group score, Lactate Dehydrogenase levels, stage, histopathology, and lesion size.

Primary melanoma of the rectum: a case report of a rare tumor.

Malignant melanoma has a generally poor prognosis and occurs primarily on the skin but may rarely be found in internal organs such as the small intestine, colon, or rectum. Case presentation: This report presents a case of a 78-year-old male patient with stage IV gastrointestinal melanoma, which is a rare form of melanoma. The patient received first-line pembrolizumab with a complete response. Clinical discussion: Surgery plays a crucial role in local and regional control for patients with localized stages. Immune checkpoint inhibitor therapy, including nivolumab or pembrolizumab, is a well-studied and proven effective treatment option for patients with advanced skin melanoma. In this case report, the patient with gastrointestinal melanoma also had a very good response to immunotherapy. Conclusions: Understanding gastrointestinal melanoma is still limited due to the rarity of this clinical entity. Currently, there are no standard treatment guidelines for this rare group of patients. Immune checkpoint inhibitors could be the preferred first-line therapy for patients with distant metastases.

Hematochezia due to arteriovenous malformation of the mesoappendix: a rare case report.

An arteriovenous malformation (AVM) of the mesoappendix is a very rare clinical entity. The clinical features, diagnosis and management of an AVM of the mesoappendix have yet to be sufficiently explained since reports about it are scarce. We report a 57-year-old man presented with hematochezia for 2 weeks. Upper and lower endoscopic could not find the source of bleeding. Abdominal contrast-enhanced computed tomography revealed an AVM of the mesoappendix. A laparoscopic appendectomy was performed, and he had a resolution of his symptoms. Intraoperative findings and pathological results confirmed the diagnosis of AVM of the mesoappendix.

Expert consensus on improving iron deficiency anemia management in obstetrics and gynecology in Asia.

Iron deficiency anemia (IDA) is a major health burden among women in Asia. Key issues in IDA management in Asia are under-diagnosis and under-treatment. The lack of Asia-specific guidelines, and suboptimal utilization of treatment compounds the management of IDA. To address these gaps, a panel of 12 experts in obstetrics, gynecology, and hematology from six regions in Asia convened to review current practices and clinical evidence and provide practical guidance on IDA diagnosis and management in Asian women. The Delphi approach was used to obtain objective opinions and attain consensus on statements pertaining to awareness, diagnosis, and management of IDA. In total, 79 statements attained consensus and are summarized to provide guidance on raising awareness of IDA and approaches for improved diagnosis and treatment of IDA among women in various settings: pregnancy, postpartum, heavy menstrual bleeding, gynecologic cancers, and perioperative care. This clinician-led consensus integrates appropriate recommendations based on clinical evidence and best practices and is intended to guide decision making in the management of iron deficiency/IDA in women. The expert panel raises a call for timely diagnosis and utilization of appropriate treatment, including use of high-dose intravenous iron, stringent blood management, and interdisciplinary collaboration, for optimization of IDA management among women in Asia.
