Aortic Chordae Tendineae Strands with Significant Aortic Regurgitation.

The aortic chordae tendineae strands are suggested to be embryonic remnants of the cusp formation process. We herein describe a 70-year-old male who was admitted to our hospital for shortness of breath and chest tightness. During echocardiographic examination, severe aortic regurgitation with a ruptured fibrous strand was detected. Moreover, another fibrous strand was found by three-dimensional transesophageal echocardiography (TEE). To our knowledge, this is the first literature review of aortic chordae tendineae strands, including diagnosis, management, and mechanisms of aortic regurgitation due to such informal strands.

ECHO Care: Providing Multidisciplinary Specialty Expertise to Support the Care of Complex Patients.

BACKGROUND: Programs for high-need, high-cost (HNHC) patients can improve care and reduce costs. However, it may be challenging to implement these programs in rural and underserved areas, in part due to limited access to specialty consultation. AIM: Evaluate the feasibility of using the Extension for Community Health Outcomes (ECHO) model to provide specialist input to outpatient intensivist teams (OITs) dedicated to caring for HNHC patients. SETTING: Weekly group videoconferencing sessions that connect multidisciplinary specialists with OITs. PARTICIPANTS: Six OITs across New Mexico, typically consisting of a nurse practitioner or physician assistant, a registered nurse, a counselor or social worker, and at least one community health worker. PROGRAM DESCRIPTION: OITs and specialists participated in weekly teleECHO sessions focused on providing the OITs with case-based mentoring and support. PROGRAM EVALUATION: OITs and specialists discussed 427 highly complex patient cases, many of which had social or behavioral health components to address. In 70% of presented cases, the teams changed their care plan for the patient, and 87% reported that they applied what they learned in hearing case presentations to other HNHC patients. DISCUSSION: Pairing the ECHO model with intensive outpatient care is a feasible strategy to support OITs to provide high-quality care for HNHC patients.

A Novel Intervention for High-Need, High-Cost Medicaid Patients: a Study of ECHO Care.

BACKGROUND: A small number of high-need patients account for a disproportionate amount of Medicaid spending, yet typically engage little in outpatient care and have poor outcomes. OBJECTIVE: To address this issue, we developed ECHO (Extension for Community Health Outcomes) Care™, a complex care intervention in which outpatient intensivist teams (OITs) provided care to high-need high-cost (HNHC) Medicaid patients. Teams were supported using the ECHO model™, a continuing medical education approach that connects specialists with primary care providers for case-based mentoring to treat complex diseases. DESIGN: Using an interrupted time series analysis of Medicaid claims data, we measured healthcare utilization and expenditures before and after ECHO Care. PARTICIPANTS: ECHO Care served 770 patients in New Mexico between September 2013 and June 2016. Nearly all had a chronic mental illness, and over three-quarters had a chronic substance use disorder. INTERVENTION: ECHO Care patients received care from an OIT, which typically included a nurse practitioner or physician assistant, a registered nurse, a licensed mental health provider, and at least one community health worker. Teams focused on addressing patients' physical, behavioral, and social issues. MAIN MEASURES: We assessed the effect of ECHO Care on Medicaid costs and utilization (inpatient admissions, emergency department (ED) visits, other outpatient visits, and dispensed prescriptions. KEY RESULTS: ECHO Care was associated with significant changes in patients' use of the healthcare system. At 12 months post-enrollment, the odds of a patient having an inpatient admission and an ED visit were each reduced by approximately 50%, while outpatient visits and prescriptions increased by 23% and 8%, respectively. We found no significant change in overall Medicaid costs associated with ECHO Care. CONCLUSIONS: ECHO Care shifts healthcare utilization from inpatient to outpatient settings, which suggests decreased patient suffering and greater access to care, including more effective prevention and early intervention for chronic conditions.

Robotic versus conventional laparoscopic surgery for rectal cancer: systematic review and meta-analysis.

BACKGROUND: The purpose of this meta-analysis is to evaluate the evidence available on the safety as well as effectiveness of robotic resection as compared to conventional laparoscopic surgery for rectal cancer. MATERIAL AND METHODS: A comparison of laparoscopic and robotic surgical treatments for rectal cancer was collected. Eligible trials that analyzed probabilistic hazard ratios (HR) for endpoints of interest (including perioperative morbidity) and postoperative complications were included in our review. RESULTS: A total of six studies were included based on the present inclusion criteria. The pooled data showed that R-TME appeared to have association with remarkable reduction in the postoperative morbidity rate as compared to L-TME. Moreover, R-TME was also linked to lower conversion, decreased lymph node number, and longer operation time compared with L-TME. However, there was no difference in hospital stay, positive range of circumferential resection and blood loss between the two study groups. CONCLUSIONS: Robotic rectal cancer surgery provides favorable outcomes and is considered as a safe surgical technique in terms of postoperative oncological safety. Like laparoscopic TME surgery, robotic surgery may be a valid alternative and complementary approach with beneficial effects on minimally-invasive surgery.

Integrated physical and mental management for China's elderly: insights from Long-gang District, Shenzhen.

China is in a period of rapid population aging. The total population of the elderly aged 60 and above in mainland China was 264 million in 2020, and is the country with the largest elderly population in the world, which is home to 1/5 of the world's older people. The urgency of actively coping with the aging population has never been greater, and China has raised it to the height of national strategy. To this end, China has issued several plans and projects on aging work. Many of them include multiple overlapping components. The management of physical illness and mental illness in the elderly is over-differentiated and segmented. However, it is common for older adults with complex health problems. The body and mind are inherently integrated and interact with each other, and should not be separated. There is an urgent need for integrated healthcare services for the physical and mental health of the elderly population. The national basic public health services play an important role in early detection and awareness of health problems for the elderly in community health services. This paper introduces the elderly health management services, one of the national basic public health projects, and the psychological care project for the elderly in Shenzhen, Guangdong Province, China. Taking Long-gang District's exploration of the joint management of physical and mental health of the elderly as an example, this review discusses the difficulties of the elderly health work, and the feasibility of integrating the elderly mental health and physical health in medical care. We outlook to build an integrated platform for physical and mental health of the elderly in China. Focus on the needs of older population, strengthen community health services, build a integrative team, fully publicize and improve health literacy of the elderly, link up and down and work together, improve coordination between providers of medical care and social services. It is of great significance to construct a strong public health system for the elderly and promote the realization of the grand goal of Healthy China.

Anatomical studies and early results on endoscopic transoral medial pterygomandibular fold approach to salvage retropharyngeal lymphadenectomy in nasopharyngeal carcinoma.

OBJECTIVE: Retropharyngeal lymphadenectomy is challenging. This study investigated a minimally invasive approach to salvage retropharyngeal lymphadenectomy in patients with nasopharyngeal carcinoma. METHODS: An anatomical study of four fresh cadaveric heads was conducted to demonstrate the relevant details of retropharyngeal lymphadenectomy using the endoscopic transoral medial pterygomandibular fold approach. Six patients with nasopharyngeal cancer with retropharyngeal lymph node recurrence, who underwent retropharyngeal lymphadenectomy with the endoscopic transoral medial pterygomandibular fold technique at the Eye and ENT Hospital of Fudan University from July to December 2021, were included in this study. RESULTS: The anatomical study demonstrated that the endoscopic transoral medial pterygomandibular fold approach offers a short path and minimally invasive approach to the retropharyngeal space. The surgical procedure was well tolerated by all patients, with no significant post-operative complications. CONCLUSION: The endoscopic transoral medial pterygomandibular fold approach is safe and efficient for retropharyngeal lymphadenectomy.

[Acquiring laparoscopic skill for colorectal surgery: based on the experience of a colorectal surgeon].

OBJECTIVE: Laparoscopic colorectal surgery is a skill-dependent procedure. The present study aims to analyze the learning curve of a properly trained surgeon, with basic laparoscopic techniques, to become skillful in performing laparoscopic colorectal operations. METHODS: A series of non-selective, consecutive 189 cases of laparoscopic colorectal surgery were accomplished, from December 2009 to February 2012, by one surgeon with years of skilled technique in laparoscopic cholecystectomy, rich experience in assisting laparoscopic colorectal surgery, and experience of approximately 180 procedures of gastric and colorectal surgery annually. 170 out of 189 procedures were radical operations for colorectal neoplasma, including right colectomies in 28 cases, left colectomies in 5 cases, sigmoidectomies in 28 cases, high Dixon procedures in 45 cases, low Dixon (total mesorectal excision, TME) procedures in 41 cases and Miles procedure in 23 cases. 19 other patients underwent combined procedures for multi-primary tumors or inflammatory enteritis. All these procedures were analyzed according to time span (the earlier half and later half) in respect to length of surgery, intraoperative blood loss, number of lymph nodes retrieved, intraoperative events and postoperative complications. RESULTS: For radical right colectomy, the D2 dissection conducted in the earlier phase (n = 8) had the similar length of surgery, more blood loss and less LN retrieval, compared with the D3 dissection conducted in recent phase (n = 20). The earlier performed high Dixon procedures (n = 22) consumed longer time than the later procedures (n = 23) consumed, but with similar blood loss and LN retrieval. Low Dixon (TME) procedures showed significant differences in length of surgery and blood loss relative to time span. Recently performed simoidectomy and Miles procedures showed a trend of shorter time consumed compared with earlier performed procedures. Conversion ratio to open surgery was 1.05%. Adverse effects occurred in 8 cases of surgeries, including intestinal injury (3/189), insufficient distal margin (2/189), intraoperative bleeding (2/189) and vaginal injury (1/76). There was no operative death. Chief complications included urinary retention 5.82%, ileus 4.76%, anastomotic leak 4.24%, perineal infection 23.08% (6/26), wound dehiscence 2.65%, gastrointestinal bleeding 1.59%, peritoneal infection 1.06%. Surgery for distal rectum tended to have more complications, such as urinary retention, anastomotic leak and perineal infection. The later performed low Dixon procedures produced insignificantly fewer anastomotic leaks than those in the earlier phase. CONCLUSIONS: For a trained surgeon with basic laparoscopic techniques, there are at least 15 - 25 cases of different procedures needed for him/her to become skilled to perform laparoscopic surgery. The learning curve should also depend on the annual number of colorectal surgeries.

No association between low-dose reserpine use and depression in older hypertensive patient: result of a multicenter, cross-sectional study.

BACKGROUND: Reserpine is currently used by millions of Chinese hypertensive patients, in spite of the continued concern of its depressogenic effect, even when used in low dose. This study aimed to investigate the association between low-dose reserpine use and depression in older Chinese hypertensive patient. METHODS: In this cross-sectional, case-control study, we recruited patient aged 60 years or over who had regularly taken one or two tables of "compound reserpine and triamterene tablets (CRTTs)" for more than one year (reserpine user) from 26 community health centers located in 10 provinces in China. For each patient who took CRTTs, we selected an age (within five years) and sex matched hypertensive patient who had never taken any drugs containing reserpine (non-reserpine user) as control. Depressive symptoms were evaluated using a Chinese depression scale adapted from the Zung Self-Rating Depression Scale. Demographic, clinical data and laboratory examination results within six months were collected. RESULTS: From August 2018 to December 2018, 787 reserpine user and 787 non-reserpine user were recruited. The mean age of all study subjects was 70.3 years, with about equal numbers of males and females. The mean depression score was 40.4 in reserpine users and 40.6 in non-reserpine users (P = 0.7). The majority of study subject had a depression score < 53 (87.6% in reserpine users and 88.2% in non-reserpine users, respectively). There were no significant differences in the prevalence of mild, moderate or severe depression in reserpine users and non-reserpine users. CONCLUSIONS: There is no association between low-dose reserpine use and depression in older hypertensive patient. The role of reserpine in the treatment and control of hypertension should be reconsidered; and further studies, especially randomized, controlled clinical trials to compare efficacy and safety of reserpine and other widely recommended anti-hypertensive agents are needed.

Non-bleeding technique in resection of hepatoma: report of 49 cases.

OBJECTIVE: To investigate the experience and some related problems of non-bleeding technique in partial hepatectomy. METHODS: 49 cases of hepatic tumors were reviewed, including 41 cases of hepatic carcinoma, 3 cases of secondary hepatic carcinoma, 4 cases of haemangioma, and 1 case of hepatic adenoma. Three kinds of bleeding control technique including normothermic complete hepatic vascular exclusion (47/49), complete vascular isolation with hypothermic perfusion (1/49), and partial extracorporeal hepatectomy (1/49) were employed. RESULTS: The intraoperative volume of blood loss was 1560+/-1252 ml, and operative duration was 4.7+/-0.8 h. One case died perioperatively because of severe bleeding. 31 cases of primary hepatic carcinoma were followed up, the 0.5-, 1-, and 5-year survival rates were 77% (24/31), 55% (17/31), and 36% (11/31) respectively. CONCLUSIONS: In liver surgery concerning hepatoma in the segment of Couinaud I, IV, V or VIII, Pringle's procedure is still the major method for bleeding control. When the vena cava or/and venae hepaticae was/were implicated, normothermic complete hepatic vascular exclusion is helpful. The partial extracorporeal technique can provide a good exposure to the cava inferior, and is an alternative to the complete extracorporeal method. Intraoperative B ultrasound detection plays an important role in choosing bleeding control technique.

Endovascular coil embolization of a costocervical trunk pseudoaneurysm after bullectomy with pleural abrasion.

Transarterial embolization (TAE) is less invasive than surgery for the treatment of pseudoaneurysms. Costocervical trunk (CCT) pseudoaneurysms are extremely rare. We herein report an unusual case of a 45-year-old man with a CCT pseudoaneurysm caused by a bullectomy with pleural abrasion, which had been performed to manage a spontaneous pneumothorax. The patient presented with chronic chest pain and successfully underwent TAE with a metallic coil. The chest pain completely disappeared 2 weeks after the TAE, and follow-up computed tomography showed that the pseudoaneurysm had almost completely disappeared 9 months after the TAE.
