Feasibility of middle colic artery as a landmark for superior mesenteric artery - first approach in laparoscopic pancreatoduodenectomy: a prospective study.

BACKGROUND: SMA-first approach in pancreatoduodenectomy (PD) has been widely applied in open surgery as well as laparoscopy. Finding the superior mesenteric artery (SMA), inferior pancreatoduodenal artery (IPDA), first jejunal artery (J1A) has become a great challenge in laparoscopic PD (LPD). Meanwhile, exposing the midde colic artery (MCA) might be a feasible approach to determine SMA, IPDA, and J1A. Our study aims to find the anatomical correlation between MCA and SMA, IPDA, J1A, especially in SMA-first approach LPD from the left. METHODS: Uncontrolled clinical trial with 33 patients undergoing LPD had preoperative contrast abdominal CT scan to analyze the anatomical relevance between MCA and SMA, J1A, IPDA. The operation was performed starting with exposing MCA in advance to find SMA, J1A and IPDA. The data was analyzed by SPSS 25.0. RESULTS: 90.9% of MCA started at 12-3 o'clock from SMA, the mean distance from the SMA root to the MCA and J1A was 56.4 mm and 37.4 mm, respectively. The distance between SMA and J1A was 19 mm. 72.7% J1A started at 9-12 o'clock, 69.7% J1A and IPDA had a common trunk. 78.8% IPDA started at 3-6 o'clock. 100% of the cases had J1A controlled intraoperatively, 81.8% for IPDA when approached from the left, 3% had MCA injury. The mean time to approach from the left was 98 min, median blood loss was 100 ml. CONCLUSION: Exposing MCA first helps determine SMA, J1A and IPDA safely, efficiently and faciliates SMA-first approach LPD from the left and complete dissection of the mesopancreas and lymph nodes.

Insulin signaling and its application.

The discovery of insulin in 1921 introduced a new branch of research into insulin activity and insulin resistance. Many discoveries in this field have been applied to diagnosing and treating diseases related to insulin resistance. In this mini-review, the authors attempt to synthesize the updated discoveries to unravel the related mechanisms and inform the development of novel applications. Firstly, we depict the insulin signaling pathway to explain the physiology of insulin action starting at the receptor sites of insulin and downstream the signaling of the insulin signaling pathway. Based on this, the next part will analyze the mechanisms of insulin resistance with two major provenances: the defects caused by receptors and the defects due to extra-receptor causes, but in this study, we focus on post-receptor causes. Finally, we discuss the recent applications including the diseases related to insulin resistance (obesity, cardiovascular disease, Alzheimer's disease, and cancer) and the potential treatment of those based on insulin resistance mechanisms.

Characterizing Patients with Uncontrolled Blood Pressure at an Urban Hospital in Hanoi, Vietnam.

Great efforts to advance the diagnosis and treatment of hypertension for controlling hypertension have been made; however, the rates of uncontrolled blood pressure are still high. This study explored the rate of uncontrolled hypertension in patients with hypertension managed in an urban hospital of Vietnam and identified associated factors. A cross-sectional survey was performed from August to October 2019 among hypertensive patients at an urban hospital in Hanoi, Vietnam. Blood pressure was evaluated at the time of medical examination. Demographic, clinical, and behavioral characteristics were also collected. Multivariate logistic regression was used to identify the factors related to uncontrolled hypertension. Among 220 patients, the rate of uncontrolled hypertension was 40.5%. Females had a lower likelihood of having uncontrolled hypertension compared to males (adjusted OR = 0.33; 95% CI = 0.11-0.98). Higher duration of diseases (adjusted OR = 1.07; 95% CI = 1.01-1.14) and higher body mass index (adjusted OR = 1.23; 95% CI = 1.05-1.45) were positively associated with uncontrolled hypertension. Patients who carried supplies needed for self-care, cut down on stress, exercised regularly, and stopped/cut down on smoking were also less likely to develop uncontrolled hypertension. This study reveals that uncontrolled hypertension was common among hypertensive patients in Vietnam. Improving self-care capacity and encouraging healthy behaviors are critically important to control blood pressure, particularly among patients who were males and had high disease duration and body mass index.

The role of controlling behaviour in intimate partner violence and its health effects: a population based study from rural Vietnam.

BACKGROUND: Studies in North America and other high-income regions support the distinction between extreme "intimate terrorism" and occasional "situational couple violence", defined conceptually in terms of the presence or absence of controlling behaviour in the violent member of the couple. Relatively little research has been conducted on the different forms intimate partner violence may take in low-income countries. The aim of this study was to investigate whether these expressions of intimate partner violence in one low-income country, Vietnam, adhere to patterns observed in western industrialised countries as well as to investigate the resulting health effects. METHODS: This cross-sectional study collected structured interview data from 883 married women aged 17-60, using the Women's Health and Life Experiences questionnaire developed by WHO. Intimate partner violence was assessed by past-year experience of physical or sexual violence and control tactics were assessed using six items combined into a scale. Three different health parameters constituted the dependent variables. Bi- and multivariate analyses, including effect modification analyses, were performed. RESULTS: Of the participants, 81 (9.2%) had been exposed to physical or sexual violence during the past 12 months; of these, 26 (32.1%) had been subjected to one or more controlling behaviours by their partners. The risk of ill health associated with combined exposure was elevated eight to 15 times, compared to a two-fourfold risk increase after exposure to only one of the behaviours, i.e. violent acts or control tactics. CONCLUSION: Physical or sexual violence combined with control tactics acted synergistically to worsen health in rural Vietnamese women. The occurrence of such violence calls for altered policies, increased research and implementation of preventive and curative strategies. The unacceptability of intimate partner violence as a part of normal Vietnamese family life must be recognised in the general debate.

Intimate partner violence against women in rural Vietnam--different socio-demographic factors are associated with different forms of violence: need for new intervention guidelines?

BACKGROUND: This population-based study investigated the different forms, magnitude and risk factors of men's violence against women in intimate relationships in a rural part of northern Vietnam and whether a difference in risk factors were at hand for the different forms of violence. Vietnam has undergone a rapid transition in the last 20 years, moving towards a more equal situation for men and women however, Confucian doctrine is still strong and little is known about men's violence against women within the Vietnamese family. METHODS: This is a cross-sectional population-based study that used a questionnaire developed by the World Health Organisation for investigating women's health and violence against women in different settings. Face-to face structured interviewing was performed and 883 married women, aged 17 to 60 participated. Bi- and multivariate analyses was used for risk factor assessment. RESULTS: The lifetime prevalence of physical violence was 30.9 percent and past year prevalence was 8.3 per cent, while the corresponding figures for physical and sexual violence combined was 32.7 and 9.2 percent. The lifetime prevalence was highest for psychological abuse (27.9 percent) as a single entity. In most cases the violence was of a severe nature and exercised as repeated acts over time. Woman's low educational level, husband's low education, low household income and the husband having more than one wife/partner were risk factors for lifetime and past year physical/sexual violence. The pattern of factors associated with psychological abuse alone was however different. Husband's low professional status and women's intermediate level of education appeared as risk factors. CONCLUSION: Men's violence against women in intimate relationships is commonly occurring in rural Vietnam. There is an obvious need of preventive and treatment activities. Our findings point at that pure psychological abuse is different from physical/sexual violence in terms of differing characteristics of the perpetrators and it might be that also different strategies are needed to reduce and prevent this violence.
